The loss of eyesight, often caused by retinal degeneration, is a life-altering health issue for many people, especially as they age. But a new development toward a prosthetic retina could help counter conditions that result from problems with this crucial part of the eye.
Chemists have succeeded in twisting a molecule by combining molecular strands of differing lengths. The longer strand winds around a central axis like a staircase banister, creating a helical structure that exhibits special physical properties.
Researchers showed it is possible to create an electrical channel a few atoms wide within two-dimensional insulating materials. Their simulations open new perspectives for the production of new electronic and photovoltaic devices.
Designkriterien für nachhaltige Nanomaterialien (DENANA) - so heisst das neue Verbundprojekt, das das Bundesministerium für Bildung und Forschung in den kommenden drei Jahren mit über 3,2 Millionen Euro foerdert.
Scientists unveiled an unprecedented spin relaxation mechanism unique to graphene, and related with entanglement of spin and pseudospin quantum degrees of freedom in presence of weak spin-orbit coupling effects. This phenomenon revisits years of controversies and opens a new window into the challenge of manipulating spin degree of freedom in future information-processing technologies.
Researchers have determined the microscopic origin of an unusual form of magnetic heat transport. The team reports on how magnetic 'quasi-particles', known as magnons, propagate in Lu2V2O7, the first material to exhibit the thermal magnon Hall effect: the magnetic transport of heat perpendicular to a temperature gradient.
Tiny, thin microtubes could provide a scaffold for neuron cultures to grow so that researchers can study neural networks, their growth and repair, yielding insights into treatment for degenerative neurological conditions or restoring nerve connections after injury.
