Phys.org / Team develops modulator for compact photonic integrated circuits
Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics that enables high-efficiency optical signal control within a small device footprint. The development ...
Phys.org / Why stars spin down, or up, before they die
From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down." The sun's total angular momentum has declined as material is gradually blown off at the surface ...
Medical Xpress / New scoring tool shows radiation can reprogram pancreatic tumor environment
A new study by researchers at Fox Chase Cancer Center focusing on pancreatic cancer has shown that a new scoring system can provide a single numerical value that reflects whether the tumor microenvironment, the biological ...
Medical Xpress / Smart implants: How robotic micro-actuators are enhancing bone healing
Smart implants that not only stabilize a fracture but also monitor the healing process from day one—and deliver targeted support when required—are currently being developed at Saarland University by a team of engineers, medical ...
Tech Xplore / Thin polymer films—the material behind a new generation of pumps
An ultrathin silicone film being developed at Saarland University enables pumps to operate without motors, without compressed air and without lubricants or external sensors. These film-based pumps can be switched on and off ...
Phys.org / Alternating atomic layers enable rare electron pairing mechanism in new unconventional superconductor
Superconductors, materials that can conduct electricity with a resistance of zero, have proved to be highly promising for the development of quantum technologies, medical imaging devices, particle accelerators and other advanced ...
Phys.org / Pressure-tuned quantum spin liquid-like behavior observed in material Y-kapellasite
A quantum spin liquid is a phase of matter in which the magnetic moments in a material do not align or freeze, even at temperatures close to absolute zero (i.e., at 0 K). The experimental realization of this highly dynamic ...
Tech Xplore / Energy-efficient cooling elements developed from a 3D printer
Visitors to this year's Hannover Messe can experience a sudden drop in temperature at first hand—all brought about by simply stretching a metal alloy and then releasing it again. The underlying elastocaloric technology offers ...
Phys.org / Water simulation of famous quantum effect reveals unexpected wave patterns
In the quirky quantum world, particles can be affected by forces that they never directly encounter. A classic example is the Aharonov–Bohm (AB) effect, where electrons are affected by a magnetic field, despite not passing ...
Tech Xplore / Engineered wood provides solar power even after the sun goes down
While sustainable solar energy can potentially meet our global power needs, it has one major flaw. When sunlight disappears, solar panels stop generating electricity. The problem is that while they do an excellent job of ...
Tech Xplore / Electric vehicles pass tipping point, breaking the link with oil prices
When the Strait of Hormuz first closed in March and oil hit US$120 a barrel, a very old question came back: is this finally the moment electric vehicles take off for good—or just another false start?
Phys.org / Zirconia thin films unlock new reversible nonpolar-to-polar mechanism
Researchers from National Taiwan University break traditional frameworks by unveiling a new symmetry-transition mechanism in ZrO2 thin films, achieving ultra-stable antiferroelectric behavior for up to 108 cycles.
