New hybrid material simplifies organic transistor design
Two teams pave way for advances in 2D materials
Highly efficient nanoparticles could bring down the cost of fuel cells
(Phys.org) —Fuel cells are a promising, non-polluting way to power cars, but their platinum catalysts are so expensive that there's no way current technology could be economically scaled up for widespread ...
Deep within spinach leaves, vibrations enhance efficiency of photosynthesis
Biophysics researchers at the University of Michigan have used short pulses of light to peer into the mechanics of photosynthesis and illuminate the role that molecule vibrations play in the energy conversion ...
Boron 'buckyball' discovered
The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a new ball on the pitch.
Rare byproduct of marine bacteria kills cancer cells by snipping their DNA
(Phys.org) —Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.
Getting more electricity out of solar cells
(Phys.org) —When sunlight shines on today's solar cells, much of the incoming energy is given off as waste heat rather than electrical current. In a few materials, however, extra energy produces extra electrons—behavior ...
Switchable material could harness the power of the sun—even when it's not shining
It's an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn't shine.
(Phys.org) —Using water as fuel has been a recurrent theme of science fiction since the days of Jules Verne. A recent discovery, however, may bring it one step closer to science fact by mimicking the very ...
Study shows short peptides can self-assemble into catalysts
Researchers identify key intermediate steps in artificial photosynthesis reaction
(Phys.org) —Artificial photosynthesis, in which we emulate the process used by nature to capture energy from the sun and convert it into electrochemical energy, is expected to be a major asset in any sustainable ...
Artificial leaf jumps developmental hurdle
In a recent early online edition of Nature Chemistry, ASU scientists, along with colleagues at Argonne National Laboratory, have reported advances toward perfecting a functional artificial leaf.
Researchers teach old chemical new tricks to make cleaner fuels, fertilizers
University researchers from two continents have engineered an efficient and environmentally friendly catalyst for the production of molecular hydrogen (H2), a compound used extensively in modern industry ...
New simple, inexpensive graphene treatment method could unleash new uses
Graphene, a two-dimensional array of carbon atoms, has shown great promise for a variety of applications, but for many suggested uses the material requires treatments that can be expensive and difficult to ...
