Researchers design and patent graphene biosensors

17-Nov-2015 - Label-free biosensors are relatively new in biochemical and pharmaceutical laboratories, and have made work much easier. The sensors enable researchers to detect low concentrations of biologically significant molecular substances (RNA, DNA, proteins, including antibodies and antigens, viruses and ...

Imitating synapses of the human brain could lead to smarter electronics

13-Nov-2015 - Making a computer that learns and remembers like a human brain is a daunting challenge. The complex organ has 86 billion neurons and trillions of connections - or synapses - that can grow stronger or weaker over time. But now scientists report the development of a first-of-its-kind synthetic ...

Advance could bring commercial applications for silver nanowires

11-Nov-2015 - Silver nanowires hold promise for applications such as flexible displays and solar cells, but their susceptibility to damage from highly energetic UV radiation and harsh environmental conditions has limited their commercialization. New research suggests wrapping the nanowires with an ultrathin ...

Using hydrogen to enhance lithium ion batteries

Lithium ion batteries operate longer and faster when treated with hydrogen.

09-Nov-2015 - Lithium ion batteries (LIBs) are a class of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. The growing demand for energy storage emphasizes the urgent need for higher-performance batteries. ...

Graphene could take night-vision technology beyond 'Predator'

06-Nov-2015 - Movies such as 1987's "Predator," in which an alien who sees in the infrared hunts down Arnold Schwarzenegger and his team, introduced a generation of sci-fi fans to thermal imaging. Since then, heat-sensing devices have found many real-word applications but have remained relatively expensive and ...

Ultrasensitive sensors made from boron-doped graphene

04-Nov-2015 - Ultrasensitive gas sensors based on the infusion of boron atoms into graphene -- a tightly bound matrix of carbon atoms -- may soon be possible, according to an international team of researchers from six countries. Graphene is known for its remarkable strength and ability to transport electrons ...
