Bacteria-Fighting Polymers Created with Light
Hundreds of polymers that could kill drug-resistant superbugs in novel ways can be produced and tested using light. The new method may help identify antimicrobials for a range of applications from personal care to coatings.
Briefs: Electronics & Computers
Current density is the amount of electrical current per cross-sectional area at a given point. As transistors in integrated circuits become smaller and smaller, they need higher and higher...
Briefs: Materials
Researchers have 3D-printed an array of light receptors on a hemispherical surface. This discovery could lead to a “bionic eye” that could someday help blind people see or sighted...
Briefs: Manufacturing & Prototyping
Plastics are often derived from petroleum, contributing to reliance on fossil fuels, and driving harmful greenhouse gas emissions.
Briefs: Lighting
Computer processors have continued to shrink down to nanometer sizes where there can be billions of transistors on a single chip. This phenomenon is described under Moore's Law, which...
Briefs: Electronics & Computers
Additive manufacturing (3D printing) can be used to manufacture porous electrodes for lithium-ion batteries, but because of the nature of the manufacturing process, the design of these 3D-printed...
Briefs: Manufacturing & Prototyping
Researchers have demonstrated the ability to create amorphous metal (metallic glass) alloys on large scales using 3D printing technology. Metallic glasses lack the crystalline...
Briefs: Test & Measurement
Wearable technologies are exploding in popularity in both the consumer and research spaces, but most of the electronic sensors that detect and transmit data from wearables are made of hard,...
