Published AI system can generate novel proteins that meet structural design targets



A new machine-learning system can generate protein designs with certain structural features, and which do not exist in nature. These proteins could be utilized to make materials that have similar mechanical properties to existing materials, like polymers, but which would have a much smaller carbon footprint.
Published Quantum entanglement could make accelerometers and dark matter sensors more accurate



The 'spooky action at a distance' that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones.
Published Stab-resistant fabric gains strength from carbon nanotubes, polyacrylate



Fabrics that resist knife cuts can help prevent injuries and save lives. But a sharp enough knife or a very forceful jab can get through some of these materials. Now, researchers report that carbon nanotubes and polyacrylate strengthen conventional aramid to produce lightweight, soft fabrics that provide better protection. Applications include anti-stabbing clothing, helmets and insoles, as well as cut-resistant packaging.
Published Rock, paper, scissors: Searching for stronger nonlocality using quantum computers



In the quantum world particles can instantaneously know about each other's state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.
Published Novel nanocages for delivery of small interfering RNAs



Small interfering RNAs (siRNAs) are novel therapeutics that can be used to treat a wide range of diseases. This has led to a growing demand for selective, efficient, and safe ways of delivering siRNA in cells. Now, in a cooperation between the Universities of Amsterdam and Leiden, researchers have developed dedicated molecular nanocages for siRNA delivery. In a paper just out in the Journal Chem they present nanocages that are easy to prepare and display tuneable siRNA delivery characteristics.
Published Long-distance quantum teleportation enabled by multiplexed quantum memories



Researchers report having achieved quantum teleportation from a photon to a solid-state qubit over a distance of 1km, with a novel approach using multiplexed quantum memories.
Published Chemists propose ultrathin material for doubling solar cell efficiency



Researchers are studying radical new ways to improve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly available natural material called molybdenum disulfide. Using a creative combination of photoelectrochemical and spectroscopic techniques, the researchers conducted a series of experiments showing that extremely thin films of molybdenum disulfide display unprecedented charge carrier properties that could someday drastically improve solar technologies.
Published Physicists discover transformable nano-scale electronic devices



The nano-scale electronic parts in devices like smartphones are solid, static objects that once designed and built cannot transform into anything else. But physicists have reported the discovery of nano-scale devices that can transform into many different shapes and sizes even though they exist in solid states.
Published Team designs four-legged robotic system that can walk a balance beam



Researchers have designed a system that makes an off-the-shelf quadruped robot nimble enough to walk a narrow balance beam -- a feat that is likely the first of its kind.
Published A novel platinum nanocluster for improved oxygen reduction reaction in fuel cells



Hydrogen, derived from polymer electrolyte fuel cells (PEFCs), is an excellent source of clean energy. However, PEFCs require platinum (Pt), which is a limited resource. Some studies have shown that Pt nanoclusters (NCs) have higher activity than conventionally used Pt nanoparticles, however the origin of their higher activity is unclear. Now, researchers have synthesized a novel Pt NC catalyst with unprecedented activity and identified the reason for its high performance.
Published Processing data at the speed of light



Scientists have developed an extremely small and fast nano-excitonic transistor.
Published Implantable device shrinks pancreatic tumors



Nanomedicine researchers have found a way to tame pancreatic cancer -- one of the most aggressive and difficult to treat cancers -- by delivering immunotherapy directly into the tumor with a device that is smaller than a grain of rice.
Published It's all in the wrist: Energy-efficient robot hand learns how not to drop the ball



Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects -- and not drop them -- using just the movement of its wrist and the feeling in its 'skin'.
Published Pollution monitoring through precise detection of gold nanoparticles in woodlice



Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light flashes again and the subsequent scattering reveals the nanoparticles' locations. With information about the quantity, location, and impact of gold nanoparticles within the organism, scientists can better understand the potential harm other metals may have on nature.
Published Table tennis brain teaser: Playing against robots makes our brains work harder



Brain scans taken during table tennis reveal differences in how we respond to human versus machine opponents.
Published New atomic-scale understanding of catalysis could unlock massive energy savings



In an advance they consider a breakthrough in computational chemistry research, chemical engineers have developed a model of how catalytic reactions work at the atomic scale. This understanding could allow engineers and chemists to develop more efficient catalysts and tune industrial processes -- potentially with enormous energy savings, given that 90% of the products we encounter in our lives are produced, at least partially, via catalysis.
Published Fully recyclable printed electronics ditch toxic chemicals for water



Engineers have produced fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process. By bypassing the need for hazardous chemicals, the demonstration points down a path industry could follow to reduce its environmental footprint and human health risks.
Published Two-dimensional nanoparticles with great potential



A research team has discovered how catalysts and many other nanoplatelets can be produced in an environmentally friendly way from readily available materials and in sufficient quantities.
Published Technology advance paves way to more realistic 3D holograms for virtual reality and more



Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.
Published Super-sized nanocage could deliver bigger drug cargoes



Nanocages are tiny artificial containers that can be used to deliver therapeutics to a target destination in the body. But some drug molecules are like gifts that are too big for a standard-sized nanocage 'box'. Now researchers describe how they have built a super-sized nanocage that could be used to deliver larger drug cargoes. They have built a bigger box.
