In world's first, atomic force microscope sees chemical bonds in individual molecules (w/ video)
(Phys.org)—IBM scientists have been able to differentiate the chemical bonds in individual molecules for the first time using a technique known as noncontact atomic force microscopy (AFM).
Wires turn salt water into freshwater
German researchers take a look inside molecules
Looking at individual molecules through a microscope is part of nanotechnologists' everyday lives. However, it has so far been difficult to observe atomic structures inside organic molecules. In the renowned ...
Carbon nanotubes could make efficient solar cells
(PhysOrg.com) -- Cornell researchers fabricated, tested and measured a simple solar cell called a photodiode, formed from an individual carbon nanotube.
Layered footballs: First two-dimensional organic metal made of fullerenes
(PhysOrg.com) -- Since their discovery in the mid 1980s, fullerenes have caused a sensation. The tiny hollow spheres made of 60 carbon atoms, constructed out of pentagons and hexagons like miniature soccer ...
Was life inevitable? New paper pieces together metabolism's beginnings
(Phys.org)—Describing how living organisms emerged from Earth's abiotic chemistry has remained a conundrum for scientists, in part because any credible explanation for such a complex process must draw from fields spanning ...
Researchers develop simple technique to visualize atomic-scale structures
Researchers at the California Institute of Technology (Caltech) have devised a new technique -- using a sheet of carbon just one atom thick -- to visualize the structure of molecules. The technique, which ...
Telescope Finds Elusive Buckyballs in Space for First Time
(PhysOrg.com) -- Astronomers using NASA's Spitzer Space Telescope have discovered carbon molecules, known as "buckyballs," in space for the first time.
Sunlight turns carbon dioxide to methane
Dual catalysts may be the key to efficiently turning carbon dioxide and water vapor into methane and other hydrocarbons using titania nanotubes and solar power, according to Penn State researchers.
First step toward electronic DNA sequencing: Translocation through graphene nanopores
Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.
Why silicon-based aliens would rather eat our cities than us: Thoughts on non-carbon astrobiology
Conventional wisdom has long had it that carbon-based life, so common here on earth, must surely be abundant elsewhere; both in our galaxy and the universe as a whole.
New method of measuring the mass of supermassive black holes
(Phys.org)—A new way of measuring the mass of supermassive black holes could revolutionise our understanding of how they form and help to shape galaxies.
Law of probabilities backs hopes for E.T., conference hears
The law of probabilities backs theories that we are not alone in the Universe, although an encounter with an advanced civilisation may shock our species, scientists at a conference said here on Monday.
