Sheffield Engineers Discover Some Sugars are Good for You


Innovative Technique - Formation of Blood Vessel with Sugar

For years we have been cautioned to keep away from sugar. However a latest research has come up with some amazing discoveries which could in fact be very beneficial to all. A research carried out by the Department of Materials Science and Engineering and the School of Clinical Dentistry at the University of Sheffield together with the Interdisciplinary Research Centre in Biomedical Materials Research at COMSATS Institute of Information Technology, Lahore in Pakistan, has disclosed that sugar could be helpful in supporting new blood vessel formation which is also called as angiogenesis.

The formation of new blood vessel is vital in the process of wound healing since the blood vessels are inclined in carrying blood in every area of the body that tends to eventually supply the body with oxygen and the nutrients needed for the upkeep of health.

The latest technique of stimulating the formation of the blood vessel with sugar utilised a mixture of simple as well as economical sugar added to a hydrogel bandage. This method which has been effective tends to be much simpler as well as lucrative than the more traditional techniques like adding in expensive short-lived growth factors. This latest method considered as well as established by the research group, functions due to specific group of sugars has the capability of stimulating skin healing.

2 Deoxy-D-Ribose

Professor Sheila MacNeil from the Department of Materials Science and Engineering at the University of Sheffield stated that all over the world people tend to live longer and have been experiencing more non-healing skin wounds related to age, poor blood supply together with diabetes. This tends to be complex to treat and is also expensive for healthcare system to handle.

The latest skin healing method utilising simple sugars has the potentials to assist healing of the wound in a very simple manner which means that patients tend to need less treatment; clinicians can treat more number of patients with the possibilities of savings which can be achieved by national healthcare systems.

Preliminary discovery done by Dr Muhammed Yar from COMSATS Institute of Information Technology, Lahore at the time of his research to comprehend how tumours tend to stimulate new blood vessels and he observed that a naturally occurring sugar – 2-deoxy-D-ribose is said to increase when tumours encouraged new blood vessels to be prepared.

Ground-Breaking Discovery

The team working with Professor Sheila MacNeil together with professor Ian Douglas from the University of Sheffield then investigated the ability of this group of sugars in order to stimulate the formation of new blood vessels as well as the stimulation of wound healing with together produced amazing results.

This ground-breaking discovery is a significant step in developing simple robust as well as economical wound dressing which could be utilised in the treatment of poor-healing wounds like chronic ulcers in the case of the elderly and diabetic ulcers.

The research paper had been in print in Materials today Communications in a paper titled `Deoxy-sugar releasing biodegradable hydrogels promote angiogenesis and stimulate wound healing’, by Muhammad Yar, Lubna Shahzadi, Azra Mehmood, Muhammad Imran Raheen, Sabinian Roman, Aqif Anwar Chaudhry, Ihtesham ur Rehman, C.W. Ian Douglas together with Professor Sheila MacNeil.

Enormous growth had been envisaged by the Faculty of Engineering in the past four years which is a home to 5,400 students together with more than 1,000 staff which makes it one of the largest Institutes in the country.

BMW X3 2018: With a King Called X3 M40i

The third generation of the BMW X3 will debut in Frankfurt, but it has already been revealed The German SUV will be manufactured in the United States and promises to be a bestseller Its range part of a 2.0 diesel engine of 190 horses with a price of 51,000 euros

The BMW X3 M40i acts as top of the range thanks to its 360 horsepower

The 2017 edition of the Frankfurt Motor Show will witness the presentation of the new BMW X3. A premiere forced by the huge competition in the SUV segment and reinforced by the successes that are reaping the X1 and the X5. Like the latter, it is built on the CLAR platform. However, before its official debut the BMW X3 has been presented in California. The most German SUV is born in America and the BMW X3 M40i is its best example.

It will not be until the next Frankfurt Motor Show when the third generation of the BMW X3 arrives in Europe, but we already know all its details after its presentation at the factory in Spartanburg, South Carolina, where it will be manufactured. Based on the CLAR (Cluster Architecture) platform that already uses the X5, the new SUV of the Bavarian firm will be 100 kilos lighter than its predecessor, a figure that should be taken into account if we look at its new measures. Apart from this, its design is more elaborate and complex than in the BMW X1, following the line of the BMW 5 Series or the BMW 7 Series.

To speak of a clean design is to do it of an SUV that will have a fluid design in spite of having a muscled frontal and that transmits power. Its bumper and its traditional kidney-shaped grille (larger) mark the front, although optical groups with LED technology also exude a great personality thanks to its sharper design. The anti-fog lights contribute to this sensation, for the first time with hexagonal shape in an X model. The alloy wheels in black finish give a very sporty touch to its side image, although they are reserved for the BMW X3 M40i variant. Its lines are more sculpted and marked.

In his rear, the BMW X3 marks differences with the X5. However, the third generation of the medium-sized SUV of the brand maintains the tailgate of a piece despite its widened pilots, which is associated with the opening of the moon individually and the opening without hands with sensor. This will allow a much easier access to a large boot that will have different load levels depending on the position of the seats. Its rear is completed by a small spoiler, LED optical groups and a double exhaust outlet. BMW will offer the X3 under three variants: 'xLine', 'Luxury Line' with chrome accents and 'M Sport'. The front or the rims are the main elements that change between each version.

On a mechanical level, the BMW X3 will arrive in the fall with a complete range of propellers that have been revised and that improve the features offered in the outgoing model. The range of the BMW X3 will start with the sDrive20i and xDrive20i versions. The first will not be available in Europe, while the second will be available, but none will arrive before the spring of 2018. In both cases, it would mount a four-cylinder engine associated with a Steptronic 8-speed gearbox.

This propeller offers 185 horses and 290 Newton / meter. Its acceleration from 0 to 100 kilometers per hour is set at 8.3 seconds and reaches a maximum speed of 215 kilometers per hour. The combined consumption for the European variant is 7.2 liters per 100.

The BMW X3 xDrive30i will arrive at dealerships in December 2017 and will equip a four-cylinder petrol engine associated with a Steptronic 8-gear box. Its power is 252 horses and its torque of 350 Newton / meter.

Accelerates from 0 to 100 kilometers per hour in 6.3 seconds, while its maximum speed is set at 240 kilometers per hour. Top of the range is the BMW X3 M40i with a 3.0-liter inline six-cylinder engine with the aforementioned 8-speed Steptronic box. Its power is 360 horses and its torque of 500 Newton / meter. Accelerates from 0 to 100 in 4.8 seconds and its maximum speed is 250 kilometers per hour.

For its part, the Diesel range is defined by two models. The first is the BMW X3 xDrive20d with a 2.0-liter, four-cylinder engine associated with an 8-speed Steptronic gearbox. Its power is 190 horses and its torque of 400 Newton / meter. Accelerates in 8.0 seconds from 0 to 100 kilometers per hour, while its top speed is 213 kilometers per hour. Its consumption is 5.4 liters at 100. For its part, the BMW X3 xDrive30d equipped a diesel engine with six cylinders in line with identical transmission that the range of the range. This 3.0-liter engine offers 265 horsepower and 620 Newton / meter of torque. It accelerates from 0 to 100 in 5.8 seconds, its maximum speed is 240 kilometers per hour and its combined consumption of 6.0 liters at 100.

As regards its interior, the BMW X3 presents a total renovation. It presents new and more modern finishes under the trademark of the brand, as well as a wide technological endowment that begins with the infotainment system already equipped with the Series 5 and Series 7. The dashboard is completely digital, it has three areas of air conditioning and a touch screen of 10.2 inches with Air-Touch technology that becomes the protagonist in the center console.

The new X3 will feature Head-up Display with integrated browser information. As in the exterior, there are optional packages and different versions to create personalized spaces and everything from the hand of the most complete technological equipment. The third generation of the German SUV equips Adapatito Cruise Control with Driving Assistant Plus.

It also has a lane guidance assistant and the assistant to change lanes as a result of the incorporation of the first semiautonomous driving technologies. All these semi-autonomous systems are included in the so-called BMW Connected Drive and in the BMW Co-Pilot system with complete integration of mobile devices. Some navigation or infotainment functions can be controlled by gestures or by voice commands.

Finally, with regard to its cost, BMW Group has already made public the official prices that will have in Spain the first three versions of the new SAV -Sports Activity Vehicle- of the Bavarian house, all of them with integral traction and two of the which will be Diesel: access to the range will be available with the X3 20d of 190 horses from 51,000 euros, the first six-cylinder engine will be defined by the 30d of 265 horses from 59,500 euros and, finally, the top of the range will be personified in the M40i of 360 horses from 70,500 euros.

Already on the X3 20d there is an exceptional standard equipment among which we find 18-inch alloy wheels, electric tailgate, distance control in front and rear parking, automatic three-zone climate control, LED lights, multifunctional sports leather steering wheel, light and rain sensor, adaptive cruise control with emergency braking function, hands-free, several USB sockets and intelligent emergency call, among others.

Are still pending to be included in the range the basic 20i petrol engine of 185 horses, whose cost is expected to be below its petrol-fueled counterpart, the intermediate power 30i petrol engine of 252 horses, also a few thousand euros more cheap that the 30d and, finally, a powerful X3 M of approximately 430 horses that recently captured one of our collaborators rolling down a Spanish highway with its due dose of camouflage.

Although we have talked about it throughout the article, special mention deserves the BMW X3 M40i as top of the range of the new X3. It is the first M Performance model of the series waiting for the X3 M and as such marks notable differences. It has a 3.0-liter inline six-cylinder engine with a preparation that allows you to climb laps faster and have a great capacity for recovery. This propeller offers 360 horsepower and a torque of 500 Newton / meter. This propeller is associated with a 8-speed Steptronic gearbox with Launch Control. There is no lack of the xDrive all-wheel drive system.

The BMW X3 M40i is capable of accelerating from 0 to 100 kilometers per hour in 4.8 seconds and reaches a maximum speed of 250 kilometers per hour. Their combined consumption is 8.2 to 8.4 liters per 100 kilometers, while the CO2 emissions of this SUV are set at 188 to 193 grams per kilometer. Beyond these data, it should be noted that the X3 M40i additionally presents a special adjustment and several specific details that enhance and accentuate the performance and dynamic qualities of this SUV.

What do we mean? On the one hand is the specific M Performance kit that includes an aerodynamic kit 'M', an M sports exhaust system with outputs with dark chrome finish. This kit also includes specific brakes 'M' and an exclusive setting for the chassis (optionally adaptive), which is essential to take advantage of the variable sport steering. It also equips light tires of 20 inches, while technologically they emphasize the system 'Performance Control'. It should be remembered that the BMW X3 M40i arrives in autumn and has a price in Spain of 70,500 euros.

What is HDMI 2.1? Everything You Need to Know about It

HDMI 2.1

A new age begins with the adoption of the HDMI 2.1

Most of the people don’t think much about the HDMI cables until it is broken or needs to be fixed. It should be noted that HDMI cables are widely used to render video content from the Bluray player to the television, soundbar or projector and it has a dedicated community working towards enhancing its capability for better. A new version of this cable has been developed dubbed as HDMI 2.1 which happens to be future ready thereby allowing users to view 4K to 10K from any source to their screen like a magic wand.

HDMI 2.1 The new age cable for modern needs

The technological evolution is happening at a breakneck speed especially when to comes to computing and consumer electronics. It is worth noting that HDMI 2.0 was released way back in 2013 and it had maximum ability to offer video content in 4K at 60 frames per second and now the capability of the monitors, television and others devices has been increased significantly. The HDMI 2.1 will help in doubling the performance of the cables from its earlier iteration wherein it will allow overreaching the 4K up to the massive 10K at 120 frames per second.

More pixels means requirement of greater bandwidth and it is possible only with the new advanced HDMI 2.1. These cables can easily upload the task of channelling video content at the upper limit of 48 Gbps rather than the paltry 18 Gbps. It also supports the dynamic HDR which will allow the televisions to adjust video as per the frame information. This is almost similar to the way Dolby Vision and HDRR10+ operates now days. People who love consumer virtual reality and core gaming will love to have this advanced cable to get the best experience on their televisions and consoles.

Features of the new HDMI 2.1 cables

As put forward by the HDMI Forum the new Ultra High Speed HDMI cable with boast of the HDMI 2.1 support allowing them to handle higher data load efficiently. It has highly advanced high bandwidth depending features which can help in generating uncompressed 8K video with HDR without much hassle. The best thing about these new age cable will be the ‘backward compatibility’ thereby it will be able all the pre-existing devices with ease and grace.

Some other features to be seen new HDMI cable include Variable Refresh Rate which is designed to eliminate the lag, frame tearing and stuttering for bettering game play experience. It will also have Quick Frame Transport which will help in reducing the latency in order to offer highly interactive VR experience to the users with smoother and no lag content render. Another feature worth mentioning is the Quick Media Switching which will help in eliminating the delay which causes black screen before content is displayed as it usually happens when watching movies.

The HDMI Forum will be running extensive compliance tests in the varied during the first three quarters of the next. The availability and adoption of the HDMI 2.1 in the consumer market will depend upon on the manufacturers.

Cortana now supports Google Calendar

The mere idea of a personal assistant is to do things for you with minimal effort. That is, you do not need to go to the application of time to see if it's going to rain or Google Maps to find the nearest coffee shop, but you can ask it out loud, with a mere interaction.

That's why Google responds to "Ok Google", Siri to "Hey Siri" and Cortana, in theory, should respond to "Hey Cortana". In Android it already did, but the permanent listening system caused incompatibilities with Google Now and has been deactivated since the end of 2015. Microsoft continues to expand the functionality of Cortana. After the Redmonder has already integrated its digital assistance system into Windows 10, Microsoft Edge and Office and even launched variants for the competitor platforms Android and iOS, the long overdue Google support follows. In addition to the in-house services Office 365, and LinkedIn Cortana can thus synonymous with the Google services dovetailed.

With the new support, the assistance system now has direct access to Gmail messages and Google Calendar entries. As a result, users of the service can be informed by voice command about incoming e-mails and upcoming appointments. Support expansion is also likely to increase the attractiveness of smart Cortana-based speakers such as the Harman Kardon Invoke.

Now, Cortana - the cross-platform personal assistant developed by Microsoft, is now compatible with Google Calendar. The Redmond giant has integrated a new Gmail connection to Cortana, which will allow the personal assistant to access the Google Calendar data. Thus, Windows 10 users, who frequently use their Gmail account, will now be able to directly access from Cortana calendar appointments and activate reminders.

The new Google Calendar support also allows the use of commands on speakers powered by Cortana, such as Harman Kardon's Evoke device, to access calendar information. In addition, the Cortana versions for iOS and Android will also be able to read and use Google Calendar information.

Microsoft's Google Calendar support for Cortana is now available for most PCs with Windows 10, and can be accessed by clicking, first, on the "Notebook" option of Cortana and then on "Adding a service".

In short, this new Cortana update allows quick access, through instructions or voice commands, not only to Microsoft services but also to those linked to Google. Thus, managing all our data and information will be easier from the personal computer with Windows 10 or another device that supports the Cortana personal assistant.

Ruthenium Monomers: Organic Electronics Beyond Cell Phone Screens

Ruthenium Monomers

Get ready for the age of Organic Electronics

When we think of future we assume of world of better machines, services and futuristic design and appeal taking care of our today’s problems. Organic electronics can help in achieving the very same future we think of with the help of the ruthenium monomers thereby we will get age of carbon based molecules rather than the silicon atoms.

The team behind this research

A team of researchers from the Princeton University, Georgia Institute of technology along with the Humbolt University of Berlin Germany has helped in creating such technology which will pave way for the organic electronics in the future. Their research has already published in the journal named Nature Materials wherein a piece was written on the feasibility in creation of the organic semiconductors.

Organic semiconductors created using this advanced technology backed with ruthenium monomers will help in creating a wide range of flexible electronics in near future. This will also usher an age of emerging technologies ranging from the solar energy conversion to the high quality colour displays which will be seen on the smartphones and other consumers electronics.

How organic semi-conductors are being made?

It is worth noting that the usual semiconductors are made out of silicon which has become a modern found of electronics. It allows engineers to take varied advantages associated with unique properties at controlling the electrical currents. Semiconductors are used across the devices and applications from the computing, switching to signal amplification. They can be found easily in the energy saving devices like the solar cells and the light emitting diodes. To tinker with the ability and functionality of the semiconductors researchers makes use of process called doping wherein a chemical makeup is modified in order to very small amount of impurities or chemical in it.

Organic semi-conductors are developed through using molecular dopants which ensures that it helps in creating highly efficient organic electronic devices. Scientists herein make use of very stable kind of molecular p-dopant which can be easily and successfully deployed in the devices. But so far they had been able to develop such molecular n-dopants which can work with the materials having low electron affinity than the others. The use of the n-doping on the semiconductors has helped in creating high efficiency organic light emitting diode which offers better conductivity than ever before.

What makes the new advanced technology best bet for future?

The best thing about the organic semiconductors is that it can be easily use in the fabrication of flexible devices which will help bringing energy saving products which can optimum functioning at the low temperatures. However the major disadvantage arising from the use of the organic semiconductor that it tends to have a relatively poor electrical conductivity. This disadvantage can result in causing unwanted difficulties in the processes and can even hamper the overall efficiency of the devices. However researchers have started working on improving the electrical properties of the organic semiconductors with ruthenium monomers in order to make them the best option available in the market.
