Tech Xplore / Nanoscale cryptography method gains robustness from stiction
Most of the cryptographic methods that keep important data secure use complex encryption software, and as a result, consume large amounts of power. As more and more electronic devices are being connected to the internet, ...
Phys.org / 'Mayonnaise effect' explains breakdown of 1929 viscosity equation
Mayonnaise is a staple of almost every household, yet the reason why it's so thick and viscous is a long-standing unsolved problem in physical chemistry: why does adding egg yolk to a runny mixture of oil and water increase ...
Phys.org / Light-erasable memory promising for system-on-panel displays
Researchers have designed a memory device based on atomically thin semiconductors and demonstrated that, in addition to exhibiting a good performance in general, the memory can also be fully erased with light, without any ...
Phys.org / Graphene-based wearable e-textiles move closer to commercial production
The market for e-textile clothing is forecasted to reach $5 billion by 2027, according to the market research firm IDTechEX. And while graphene is expected to be one of the most prominent materials in wearable e-textiles, ...
Phys.org / Cheap, sustainable battery made from tree bark tannins
(Phys.org)—Tannins may be best known for their presence in red wine and tea, but in a new study researchers have demonstrated for the first time that tannins from tree bark can also serve as battery cathode materials. As ...
Phys.org / Physicists show feasibility of building a trapped Rydberg ion quantum computer
(Phys.org)—Physicists have built one of the first basic elements of a trapped Rydberg ion quantum computer: a single-qubit Rydberg gate. The achievement illustrates the feasibility of building this new type of quantum computer, ...
Phys.org / Grasshopper problem yields insight into quantum theory
(Phys.org)—Like many mathematical puzzles, the grasshopper problem is simple to state but difficult to solve: A grasshopper lands at a random point on a lawn of area 1, then jumps once, a fixed distance, in a random direction. ...
Phys.org / Negative piezoelectric effect is not so rare after all
(Phys.org)—The piezoelectric effect, which causes a material to expand along the direction of an applied electric field, is common in many materials and used in a variety of technologies, from medical ultrasound to vibration-powered ...
Phys.org / Physicists set new record with 10-qubit entanglement
(Phys.org)—Physicists have experimentally demonstrated quantum entanglement with 10 qubits on a superconducting circuit, surpassing the previous record of nine entangled superconducting qubits. The 10-qubit state is the largest ...
Phys.org / Researchers transform tomatoes into fluorescent carbon dots
(Phys.org)—Researchers have shown that tomato pulp dissolved in water can eventually be turned into a powder of nanoparticles containing carbon dots with diameters of less than 5 nm. Like all carbon dots, one of the main ...
Phys.org / Digitally printed cyanobacteria can power small electronic devices
(Phys.org)—Researchers have used a simple inkjet printer to print a "bio-ink" of cyanobacteria onto a conductive surface, creating a biophotovoltaic cell. Unlike conventional photovoltaic cells that operate only when exposed ...
Phys.org / Physicists unify quantum coherence with nonclassicality of light
(Phys.org)—Physicists have demonstrated that two independently developed concepts—quantum coherence and the nonclassicality of light—both arise from the same underlying resources. The ability to explain seemingly distinct ...
Phys.org / Clothing fabric keeps you cool in the heat
(Phys.org)—Researchers have designed a thermal regulation textile that has a 55% greater cooling effect than cotton, which translates to cooler skin temperatures when wearing clothes made of the new fabric. The material can ...
Phys.org / New mirror reflects light differently than conventional mirrors
(Phys.org)—Researchers have designed a new type of mirror that reflects light in a completely different way than conventional mirrors do. The new mirror, called a chiral meta-mirror, has potential applications for information ...
Phys.org / Hard computing problem might be solvable only by quantum computers
(Phys.org)—Researchers have introduced a new computing problem and shown that it would be extremely difficult, if not impossible, for a classical computer to solve, but in theory it could be efficiently solved using quantum ...
