Plastic Waste A Hazard For Subalpine Lakes
2013-10-07 13:42:37

Cell Press Many subalpine lakes may look beautiful and even pristine, but new evidence suggests they may also be contaminated with potentially hazardous plastics. Researchers say those tiny microplastics are likely finding their way into the food web through a wide range of freshwater invertebrates too. The findings, based on studies of Italy's Lake Garda and reported on October 7th in Current Biology, a Cell Press publication, suggest that the problem of plastic pollution isn't limited...

Simulations help North and South Dakota researchers decide which technology would make a better solar collector, quantum dot or nanowire A trio of researchers at North Dakota State University, Fargo, and the University of South Dakota have turned to computer modeling to help decide which of two competing materials should get its day in the sun as the nanoscale energy-harvesting technology of future solar panels -- quantum dots or nanowires. Andrei Kryjevski and his colleagues, Dimitri...

Plasmas attack bacterial cells on several levels RUB researchers analyse the mechanism of action of UV photons and radicals As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universität (RUB). Cold atmospheric-pressure plasmas attack the prokaryote’s cell envelope, proteins and DNA....

Microscopic, bottle-like structures with corks that melt at precisely-controlled temperatures could potentially release drugs inside the body or fragrances onto the skin, according to a recently published study. Typical drug delivery systems act more like sponges than bottles. For example, drugs are absorbed into polymer particles and then allowed to diffuse out over time. The researchers hope that the new system may allow for greater control of drug delivery. Cargo would stay inside the...

Material Properties Of Containers Affect The Viscosity Of Water At The Nanoscale
2013-09-19 14:25:06

Georgia Institute of Technology Water pours into a cup at about the same rate regardless of whether the water bottle is made of glass or plastic. But at nanometer-size scales for water and potentially other fluids, whether the container is made of glass or plastic does make a significant difference. A new study shows that in nanoscopic channels, the effective viscosity of water in channels made of glass can be twice as high as water in plastic channels. Nanoscopic glass channels can...

Motorized Microscopic Matchsticks Move In Water With Sense Of Direction
2013-09-10 12:11:39

University of Warwick Chemists, physicists and computer scientists at the University of Warwick have come together to devise a new powerful and very versatile way of controlling the speed and direction of motion of microscopic structures in water using what they have dubbed chemically ‘motorized microscopic matchsticks’. Before now most research seeking to influence the direction of motion of microscopic components have had to use outside influences such as a magnetic field or the...

Wildfires Change Climate Models
2013-08-30 13:45:15

Brett Smith for redOrbit.com - Your Universe Online While raging wildfires can consume property and even lives, the towering infernos could also be heavily influencing the forces of climate change. According to a new study from researchers at Michigan Technological University, forest fires emit massive quantities of two different kinds of particles – soot and tar balls. These particles remain in the atmosphere and should be taken into account when creating climate change models, the...
