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.

Researchers have developed the first cardiac implant made from graphene, a two-dimensional super material with ultra-strong, lightweight and conductive properties. Similar in appearance to a child's temporary tattoo, the new graphene 'tattoo' implant is thinner than a single strand of hair yet still functions like a classical pacemaker.

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.

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.

The demand for battery-grade lithium, nickel, cobalt, manganese and platinum will climb steeply as vehicle electrification speeds up and nations work to reduce greenhouse gas emissions through mid-century. This surge in demand will also create a variety of economic and supply-chain problems, according to new research.

An environmentally friendlier solution to solar cell production with enhanced performance utilizes PEDOT:PSS/silicon heterojunction solar cells. This hybrid type is made of organic-inorganic material, which could potentially ease the production process compared to conventional silicon-only solar cells. It avoids manufacturing solar cells in vacuums and high-temperature processes, which require large and expensive equipment and a great amount of time.

An ancient biological enzyme known as nickel-iron hydrogenase may play a key role in producing hydrogen for a renewables-based energy economy, researchers said. Careful study of the enzyme has led chemists to design a synthetic molecule that mimics the hydrogen gas-producing chemical reaction performed by the enzyme.

Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu -- at much lower levels and much more quickly than conventional tests for either.
