Chinese scientists unveil liquid phase 3-D printing method using low melting metal alloy ink (10/24/2014)

Chinese scientists unveil liquid phase 3-D printing method using low melting metal alloy inkConventional 3-D metal printing is generally restricted to metals that have a high melting point, and the process is rather time consuming. Scientists in the Chinese capital now present an alternative technique involving liquid-phase 3-D printing to manufacture conductive metal objects rapidly. Through introducing a printing ink consisting of a four-element metal alloy, Bi35In48.6Sn16Zn0.4, with a melting point slightly above room temperature, a series of three-dimensional structures are fabricated conveniently in a cooling liquid. ...> Full Article


Blades of grass inspire advance in organic solar cells (10/23/2014)

Blades of grass inspire advance in organic solar cellsBriseno's research group is one of very few in the world to design and grow organic single-crystal p-n junctions. He says, 'This work is a major advancement in the field of organic solar cells because we have developed what the field considers the 'Holy Grail' architecture for harvesting light and converting it to electricity.' The breakthrough in morphology control should have widespread use in solar cells, batteries and vertical transistors, he adds. ...> Full Article


Taking thin films to the extreme (10/23/2014)

Taking thin films to the extremeApplying a well-known optical phenomenon called thin-film interference, a group of researchers at Harvard University has demonstrated the ability to 'paint' ultra-thin coatings onto a rough surface -- work that holds promise for making future, flexible electronic devices, creating advanced solar cells and detailing the sides of next-gen rocket ships and spacecraft with extremely lightweight decorative logos -- work described in work the journal Applied Physics Letters, from AIP Publishing. ...> Full Article


New material steals oxygen from the air (10/22/2014)

New material steals oxygen from the airResearchers from the University of Southern Denmark have synthesized crystalline materials that can bind and store oxygen in high concentrations. Just one spoon of the substance is enough to absorb all the oxygen in a room. The stored oxygen can be released again when and where it is needed. ...> Full Article


Unexpected new mechanism reveals how molecules become trapped in ice (10/22/2014)

Unexpected new mechanism reveals how molecules become trapped in iceExpanding our knowledge of the way molecules interact with ice surfaces is a key goal not only for climate change but also a much wider range of other environmental, scientific and defense-related issues. Now, a team of researchers has discovered a new mechanism they call 'stable energetic embedding' of atoms and molecules within ice. The work is described in The Journal of Chemical Physics. ...> Full Article


Scientists make droplets move on their own (10/21/2014)

Droplets are simple spheres of fluid, not normally considered capable of doing anything on their own. But now researchers have made droplets of alcohol move through water. In the future, such moving droplets may deliver medicines. ...> Full Article


Research aims to develop new, more efficient catalytic materials (10/20/2014)

In order to support the world's needs to make cheaper and more effective fuels, chemicals, polymers and more, new and more efficient catalytic materials and processes must be developed. A team of researchers, including several from Wayne State University, is tackling this problem with the help of a new grant from the National Science Foundation. ...> Full Article


Smart, eco-friendly new battery to solve problems (10/20/2014)

Smart, eco-friendly new battery to solve problemsPresent-day lithium batteries are efficient but involve a range of resource and environmental problems. Using materials from alfalfa (lucerne seed) and pine resin and a clever recycling strategy, Uppsala researchers have now come up with a highly interesting alternative. Their study will be presented soon in the scientific journal ChemSusChem. ...> Full Article

How to make stronger, 'greener' cement (10/18/2014)

Concrete is the world's most-used construction material, and a leading contributor to global warming, producing as much as one-tenth of industry-generated greenhouse-gas emissions. Now a new study suggests a way in which those emissions could be reduced by more than half -- and the result would be a stronger, more durable material. ...> Full Article


Solar cell compound probed under pressure (10/17/2014)

Solar cell compound probed under pressureGallium arsenide a semiconductor composed of gallium and arsenic is well known to have properties that promise practical applications. In the form of nanowires it has particular potential for use in solar cell manufacture and optoelectronics in many of the same applications that silicon is commonly used. But its natural semiconducting ability requires tuning to make it more desirable for use in manufacturing. New work offers a novel approach to such tuning. ...> Full Article


Longstanding bottleneck in crystal structure prediction solved (10/16/2014)

Longstanding bottleneck in crystal structure prediction solvedThe various patterns that atoms of a solid material can adopt, called crystal structures, can have a huge impact on its properties. Being able to accurately predict the most stable crystal structure for a material has been a longstanding challenge for scientists. Researchers calculated the lattice energy of benzene, a simple yet important molecule in pharmaceutical and energy research, to sub-kilojoule per mole accuracy -- a level of certainty that allows polymorphism to be resolved. ...> Full Article


Harvesting hydrogen fuel from the Sun using Earth-abundant materials (10/15/2014)

Harvesting hydrogen fuel from the Sun using Earth-abundant materialsToday, the journal Science published the latest development in Michael Grätzel's laboratory at EPFL: producing hydrogen fuel from sunlight and water. By combining a pair of solar cells made with a mineral called perovskite and low cost electrodes, scientists have obtained a 12.3 percent conversion efficiency from solar energy to hydrogen, a record using Earth-abundant materials as opposed to rare metals. ...> Full Article


2-D materials' crystalline defects key to new properties (10/14/2014)

Understanding how atoms 'glide' and 'climb' on the surface of 2-D crystals like tungsten disulphide may pave the way for researchers to develop materials with unusual or unique characteristics, according to an international team of researchers. ...> Full Article


Pressure mounts on FDA and industry to ensure safety of food ingredients (10/13/2014)

Confusion over a 1997 Food and Drug Administration (FDA) rule that eases the way for food manufacturers to use ingredients 'generally regarded as safe,' or GRAS, has inspired a new initiative by food makers. Food safety advocates say the current GRAS process allows substances into the food supply that might pose a health risk, while industry defends its record. An article in Chemical & Engineering News (C&EN) details what changes are on the table. ...> Full Article
