One of the key requirements of future optical communications technologies is a nanoscale light source capable of emitting ultrafast light pulses. In a new study, researchers have shown that graphene may be an ideal candidate ...
Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. The different colors are emitted from different parts of the quantum dot—red from the core, green from ...
As a hard and brittle material, silicon has practically no natural elasticity. But in a new study, researchers have demonstrated that amorphous silicon can be grown into superelastic horseshoe-shaped nanowires that can undergo ...
(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)—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)—Egg white—also known as egg albumen—is not only good-tasting, it also has very good dielectric properties, along with a high transparency and high elasticity, that make it a promising material for fabricating ...
(Phys.org)—In a new study, scientists have developed the microscale version of self-driving vehicles: a 5-μm spherical micromotor that autonomously navigates its way through micro-traffic along a micro-maze to reach its ...
(Phys.org)—Researchers have fabricated rechargeable batteries by using highly conductive yarns that have a diameter and flexibility similar to that of a piece of cotton yarn. The new yarn battery can be woven into fabric ...
(Phys.org)—One of the most promising microscale power sources for portable and wearable electronics is a micro-supercapacitor—they can be made thin, lightweight, highly flexible, and with a high power density. Normally, ...
(Phys.org)—Researchers have built a new type of "neuron transistor"—a transistor that behaves like a neuron in a living brain. These devices could form the building blocks of neuromorphic hardware that may offer unprecedented ...
