Increasing performance scaling with packageless processors Demand for increasing performance is far outpacing the capability of traditional methods for performance scaling. Disruptive solutions are needed to advance beyond incremental improvements. Traditionally, processors reside inside packages to enable PCB-based integration. However, a team of researchers from the Department of Electrical ... » read more

Optical communication on silicon chips With the huge increase in computing performance in recent decades achieved by squeezing ever more transistors into a tighter space on microchips, at the same time this downsizing has also meant packing the wiring within microprocessors ever more tightly together. This has led to effects such as signal leakage between components, which can slow down commun... » read more

Asphalt anode Scientists at Rice University developed an anode for lithium metal batteries enabling them to charge 10 to 20 times faster than commercial lithium-ion batteries. The anodes are a porous carbon made from asphalt mixed with conductive graphene nanoribbons and coated with composite with lithium metal through electrochemical deposition. The lab combined the anode with a sulfurized... » read more

Slowing down photonics Researchers at the University of Sydney developed a chip capable of optical data into sound waves, slowing data transfer enough to process the information. While speed is a major bonus with photonic systems, it's not as advantageous when processing data. By turning optical signals into acoustic, data can be briefly stored and managed inside the chip for processing, re... » read more

Could video goggles, and a tiny implant cure blindness? Incredibly, the world of medical research is on the verge of curing blindness. Similar to cochlear implants for deaf people, Stanford University scientists and engineers are developing new devices to this end, including a bionic vision system based on photovoltaic implants, which is awaiting approval for human clinical trials in Europe. A... » read more

USB data leakage Researchers from the University of Adelaide found that USB connections are vulnerable to information leakage. In testing more than 50 different computers and external USB hubs, they found that over 90% of them leaked information to an external USB device. "USB-connected devices include keyboards, cardswipers and fingerprint readers which often send sensitive information to ... » read more

Brain microscopes Rice University is developing a tiny and flat microscope for a special application--it will be able to decode and trigger neurons on the surface of the brain. The microscope technology, dubbed FlatScope, is part of a $65 million program announced by the U.S.-based Defense Advanced Research Projects Agency (DARPA). The DARPA project, dubbed Neural Engineering System Design ... » read more

Batteries from scrap metal Scientists at the Chinese Academy of Sciences and Jilin University found a method to transform rusty stainless steel mesh into electrodes with outstanding electrochemical properties that make them ideal for potassium-ion batteries. The rust is converted directly into a compact layer with a grid structure that can store potassium ions. A coating of reduced graphite... » read more
