Generator uses the human body as an electrode to power portable electronics
NIST revises key computer security publication on random number generation
In response to public concerns about cryptographic security, the National Institute of Standards and Technology (NIST) has formally revised its recommended methods for generating random numbers, a crucial ...
Dutch company launches new-generation urban wind turbines
Optimizing shale gas production from well to wire
"Hydraulic fracturing" (or fracking) and "environmentally friendly" often do not appear in the same sentence together. But as the United States teeters on the precipice of a shale gas boom, Northwestern University professor ...
DNA can't explain all inherited biological traits, research shows
Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows.
Electricity from biomass with carbon capture could make western US carbon-negative
Generating electricity from biomass, such as urban waste and sustainably-sourced forest and crop residues, is one strategy for reducing greenhouse gas emissions, because it is carbon-neutral: it produces ...
A nanosized hydrogen generator
(Phys.org) —Researchers at the US Department of Energy's (DOE) Argonne National Laboratory have created a small scale "hydrogen generator" that uses light and a two-dimensional graphene platform to boost ...
Researchers find a way to convert waste heat to electricity at nano-scale
Experiment opens the door to multi-party quantum communication (Update)
In the world of quantum science, Alice and Bob have been talking to one another for years. Charlie joined the conversation a few years ago, but now by enforcing the space-like separation of the three parties, ...
Nanoengineers develop basis for electronics that stretch at the molecular level
Nanoengineers at the University of California, San Diego are asking what might be possible if semiconductor materials were flexible and stretchable without sacrificing electronic function?
Power arm band for wearables harvests body heat
New method stabilizes common semiconductors for solar fuels generation
Researchers around the world are trying to develop solar-driven generators that can split water, yielding hydrogen gas that could be used as clean fuel. Such a device requires efficient light-absorbing materials ...
