Aug 04,  · Hi Alberto, First of all, thank you for your help. Right now, I have the “standard” driver. The one the computer returns to after uninstalling the current one: version from 17/07/ May 18,  · This is the latest driver version for intel 4th Generation Processors (your processor) and Intel HD Graphics (integrated in your processor). The driver version you can see in Device Manager (DM) as well. Open DM, click on Display adapters, then right click on Intel HD Graphics > Properties and finally Driver tab. Leon. This driver was provided by Intel Corporation for support of Intel HD Graphics In order to manually update your driver, follow the steps below (the next steps): 1. Go to Device Manager (right.

Nanotechnology can significantly accelerate the arrival of fuel cells

The growing need for compact and high-capacity power sources for portable devices prompts researchers to intensify the search for new solutions: fuel cells occupy a prominent place among promising candidates for the role of the “battery of the future”.

In terms of energy consumption, they already exceed the best examples of traditional batteries by an order of magnitude. If a lithium ion battery provides 300 Wh per liter of volume, a methanol fuel cell can theoretically “deliver” 4800 Wh per liter of volume! In simple terms, this means that laptops with new batteries could work for days without recharging, and the battery life of a cell phone would exceed a month. That’s why leading companies in the industry such as Toshiba, IBM and NEC are researching fuel cells.

In general terms, the principle of operation of a fuel cell is that hydrogen atoms are extracted from a chemical source, which, when interacting with a catalyst (for example, platinum), give up electrons (the current required to power the electronics is generated). The hydrogen ions generated by the process are separated from the fuel using an electrolyte and form water molecules, reacting with atmospheric oxygen. Obviously, the more fuel can be brought into contact with the catalyst, the greater the current generated by the element. So the catalyst surface is the key to battery efficiency.

So far, techniques borrowed from semiconductor manufacturing have been tried to increase surface area, such as etching or evaporating layers of material. Unfortunately, this approach turned out to be not only expensive, but also limited in effectiveness.

Researchers at the University of Wisconsin take a new approach. As a result, they managed not only to increase the efficiency of the elements, but also to completely move away from the need for complex and expensive technologies.

A porous alumina filter costing less than $ 100 was used as a material for the fuel channels. The filter is riddled with remarkable cylindrical holes with a diameter of only 200 nm, and is used in laboratories as a template for growing nanowires. Scientists created nanowires in the filter from an alloy of platinum and copper, and then dissolved the copper by impregnating the filter with nitric acid. Now, instead of solid nanowires, each hole in the filter was filled with a porous platinum electrode. Partially dissolved conductors have a very complex structure and a huge surface area.

To build a fuel cell, it remains to fill the pores with NaBH4 solution. A sheet of electrolytic filter paper was placed between arrays of nanotubes to allow the efflux of hydrogen ions. Any part of the outer surface of the “sandwich” is suitable for supplying electrodes, which simplifies the connection of the resulting power source. Cells can be connected in parallel and in series, increasing the battery current and voltage, respectively.

While still at the prototype stage, the new cell surpassed fuel cells made using lithographic technologies by an order of magnitude in terms of efficiency! Moreover, it turned out to be cheaper than them in manufacturing. Despite the impressive result, the developers believe that there is room for improvement, since, according to their own estimates, only about a third of the electrodes formed from the alloy are active in the battery.
