Sustainable energy storage is in great demand. Researchers at Uppsala University have therefore developed an all-organic proton battery that can be charged in a matter of seconds. The battery can be charged and discharged over 500 times without any significant loss of capacity. Their work has been published in the scientific journal Angewandte Chemie.
New artificial proteins have been created to function as molecular logic gates. Like their electronic counterparts in computers, these biochemical tools can be used to program the behavior of complex systems, such as gene regulation inside human T-cells. This new advance might improve the durability of future cell-based therapies.
Houston Methodist nanomedicine researchers are studying a new drug delivery system that transports oral medication via triglycerides that could eliminate the need for injections or IV treatments of some biologic drugs for rheumatoid arthritis and other autoimmune diseases. They're doing this with a diabetes drug that resulted in approximately 25% absorption in mice models, considered very high for an oral drug. The research will appear in Science Advances April 1.
A paper in the journal Physical Review Applied outlines a way to teach an AI to make an interconnected set of adjustments to the quantum dots that could form the qubits in a quantum computer's processor. Precisely tweaking the dots is crucial for transforming them into properly functioning qubits, and until now the job had to be done painstakingly by human operators, requiring hours of work to create even a small handful of qubits for a single calculation.
Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently entangled two laser beams through bouncing them off the same mechanical resonator, a tensioned membrane. This provides a novel way of entangling disparate electromagnetic fields, from microwave radiation to optical beams. Creating entanglement between optical and microwave fields would be a key step towards solving the challenge of sharing entanglement between two distant quantum computers operating in the microwave regime.
Dr. Soon Moon Jeong's research team in the Division of Energy Technology at DGIST has developed a new structure of luminescence technology. This will enable the production of light-emitting elements that overcome the limitations of existing methods, expecting to greatly help improve the efficiency of light-emitting elements used in various ways such as billboards and banners.
UC Berkeley chemists have created a hybrid system of bacteria and nanowires that captures energy from sunlight and transfers it to the bacteria to turn carbon dioxide and water into organic molecules and oxygen. On Earth, such a biohybrid could remove carbon dioxide from the atmosphere. On Mars, it would provide colonists with raw material to manufacture organic compounds ranging from fuels to drugs. The efficiency is greater than the photosynthetic efficiency of most plants.
Researchers invented a microfluidic chip containing cardiac cells that is capable of mimicking hypoxic conditions following a heart attack - specifically when an artery is blocked in the heart and then unblocked after treatment. The chip can be used to monitor electrophysiological and molecular response of the cells to heart attack conditions in real time.
Rice University theorists find that flexoelectric effects in double-walled carbon nanotubes could be highly useful for photovoltaic applications.
An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.
