DIY hearing aid for the many costs just a few dollars

From Georgia Tech has emerged a hearing aid design that can be built for a few dollars from easily obtained parts. Worn around the neck in a 3d printed case, the ‘LoCHAid’ proof-of-concept is designed to be manufactured and repaired where conventional hearing aids are priced beyond the reach of most citizens, according to the ...

Russian scientists crack Mendeleev mystery

Russian scientists have created a chemical space mapping method and cracked the mystery of Mendeleev Numbers. Scientists had long tried to come up with a system for predicting the properties of materials based on their chemical composition until they set sights on the concept of a chemical space which places materials in a reference frame ...

Organic photodiodes challenge silicon over wide areas

Large-area organic photodiodes can now offer advantages over conventional silicon photodiodes, particularly noise advantages, according to Georgia Tech, which has solution-processed flexible organic devices in arbitrarily shapes. It claims performance comparable to that of rigid silicon photodiodes in the visible light spectrum, except their response time. “What we have achieved is the first demonstration that ...

Two dimensional semiconductor shows logic-in-memory promise

Hafnium oxide two-dimensional semiconductor can be used to build logic-in-memory processors using a fabrication process that can be scaled, according to the Laboratory of Nanoscale Electronics and Structures (LANES) at Swiss lab EPFL. The chip is based on floating-gate fets, similar to those used in flash memory. “The unique electrical proprieties of MoS2 make it particularly sensitive to ...
