Professor Fernando Uribe-Romo and his team of students created a way to trigger a chemical reaction in a synthetic material called metal-organic frameworks (MOF) that breaks down carbon dioxide into harmless organic materials. Think of it as an artificial photosynthesis process similar to the way plants convert carbon dioxide and sunlight into food. But instead of producing food, Uribe-Romo’s method produces solar fuel.

Process produces energy at the same time. A chemistry professor in Florida has just found a way to trigger the process of photosynthesis in a synthetic material, turning greenhouse gases into clean air and producing energy all at the same time...

Schematic representation of the monolithically integrated SiPV–LIB device and the electrochemical performance of the bipolar LIB.

A UNIST affiliated team has developed a single-unit, photo-rechargeable portable power source based on high-efficiency silicon solar cells and lithium-ion batteries (LIBs). This newly-developed power source is designed to work under sunlight and indoor lighting, allowing users to power their portable electronics anywhere with access to light. In addition, the new device could power electric devices even in the absence of light.

In this work, the team of Professor Sang-Young Lee and Professor Kwanyoung Seo of Energy and Chemical Engineering at UNIST presented a new class of monolithically integrated, portable PV-battery systems (denoted as ‘SiPV-LIBs’) based on...

HK researchers have developed a novel surgical robotic system that provides tactile feedback and is capable of single-incision and natural orifice (incision-free) robotic surgery. The system minimizes surgical trauma and is safer than currently available robotic systems...

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about 50X higher than copper films, currently used in electronics...
