The lightest shielding material in the world
The lightest shielding material in the world
Researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range - and they are unrivalled in terms of weight. Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components or the transmission of signals.

New technique may enable all-optical data-centre networks
A new technique that synchronises the clocks of computers in under a billionth of a second can eliminate one of the hurdles for the deployment of all-optical networks, potentially leading to more efficient data centres, according to a new study led by UCL and Microsoft. Data centres, comprising tens or hundreds of thousands connected servers, are the underlying technology empowering everything we do online, from storing films and photos to serving up webpages and online services.

Critical communications component made on a flexible wooden film
In the not-too-distant future, flexible electronics will open the door to new products like foldable phones, tablets that can be rolled, paper-thin displays and wearable sensors that monitor health data. Developing these new bendy products, however, means using materials like new plastics and thin films to replace the rigid circuit boards and bulky electronic components that currently occupy the interiors of cell phones and other gadgets.

Electricity for All
Organizations like the World Bank imply that equality is an important aspect of their goals for expanding electricity access in developing countries. Yet few studies have actually addressed how to ensure equality in developing areas like sub-Saharan Africa, and many have even used methods that further inequality.

Using electrical stimulus to regulate genes
Using electrical stimulus to regulate genes
A team of researchers has succeeded in using an electric current to directly control gene expression for the first time. Their work provides the basis for medical implants that can be switched on and off using electronic devices outside the body. This is how it works. A device containing insulin-producing cells and an electronic control unit is implanted in the body of a diabetic.

Novel Electric Impulses Relieve the Pain
Novel Electric Impulses Relieve the Pain
Stimulating the vagus nerve in the ear can help relieving chronic pain. TU Wien and MedUni Vienna have developed novel, sophisticated methods for electric stimulation of the vagus nerve. The vagus nerve plays an important role in our body. It consists of various fibres, some of which connect to the internal organs, but the vagus nerve can also be found in the ear.

Wirelessly charging electric cars as they drive
Wirelessly charging electric cars as they drive
Engineers have demonstrated a practical way to use magnetism to transmit electricity wirelessly to recharge electric cars, robots or even drones. The technology could be scaled up to power electric cars as they drive over highways, robots on factory floors and drones hovering over rooftops. Stanford engineers have taken a big step toward making it practical for electric cars to recharge as they speed along futuristic highways built to "refuel" vehicles wirelessly.

Researchers solve ’link discovery’ problem for terahertz data networks
Leaky waveguide could help devices find one another on future, high-speed data networks By Kevin Stacey Special to Rice News When you open a laptop, a router can quickly locate it and connect it to the local Wi-Fi network. That ability, known as link discovery, is a basic element of any wireless network, and now a team of engineering researchers from Rice University and Brown University has developed a way to do that with terahertz radiation, the high-frequency waves that could one day make for ultrafast wireless data transmission.

Bose-Einstein condensate: magnetic particles behave repulsively
Bose-Einstein condensate: magnetic particles behave repulsively
Data transmission that works by means of magnetic waves instead of electric currents - for many scientists, this is the basis of future technologies that will make transmission faster and individual components smaller and more energy-efficient. Magnons, the particles of magnetism, serve as moving information carriers.

Fine-Tuning Magnetic Spin for Faster, Smaller Memory Devices
Fine-Tuning Magnetic Spin for Faster, Smaller Memory Devices
Unlike the magnetic materials used to make a typical memory device, antiferromagnets won't stick to your fridge. That's because the magnetic spins in antiferromagnets are oppositely aligned and cancel each other out. Scientists have long theorized that antiferromagnets have potential as materials for ultrafast stable memories.

Energy-harvesting design aims to turn Wi-Fi signals into usable power
Device for harnessing terahertz radiation might enable self-powering implants, cellphones, other portable electronics. Any device that sends out a Wi-Fi signal also emits terahertz waves -electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as "T-rays," are also produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.
