Scientists develop mesh that captures oil - but lets water through

Nano-coated mesh could clean oil spills for less than $1 per square foot


The unassuming piece of stainless steel mesh in a lab at The Ohio State University doesn't look like a very big deal, but it could make a big difference for future environmental cleanups. Water passes through the mesh but oil doesn't, thanks to a nearly invisible oil-repelling coating on its ...


Not candy crush: The nature of candy sculpture


A team of scientists has identified the complex process by which materials are shaped and ultimately dissolved by surrounding water currents. The study, conducted by researchers at NYU's Courant Institute of Mathematical Sciences and Florida State University, appears in the Journal of Fluid ...

Berkeley Lab study reveals molecular structure of water at gold electrodes


When a solid material is immersed in a liquid, the liquid immediately next to its surface differs from that of the bulk liquid at the molecular level. This interfacial layer is critical to our understanding of a diverse set of phenomena from biology to materials science. When the solid surface is ...


Professors' super waterproof surfaces cause water to bounce like a ball


In a basement lab on BYU's campus, mechanical engineering professor Julie Crockett analyzes water as it bounces like a ball and rolls down a ramp. This phenomenon occurs because Crockett and her colleague Dan Maynes have created a sloped channel that is super-hydrophobic. Engineers like Crockett ...

Novel technique enables air-stable water droplet networks


A simple new technique to form interlocking beads of water in ambient conditions could prove valuable for applications in biological sensing, membrane research and harvesting water from fog. Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a method to create ...


How to avoid water wars between 'fracking' industry and residents


The shale gas boom has transformed the energy landscape in the U.S., but in some drier locations, it could cause conflict among the energy industry, residents and agricultural interests over already-scarce water resources, say researchers. They add that degraded water quality is a potential risk ...


Researchers question emergency water treatment guidelines


The Environmental Protection Agency's (EPA's) recommendations for treating water after a natural disaster or other emergencies call for more chlorine bleach than is necessary to kill disease-causing pathogens and are often impractical to carry out, a new study has found. The authors of the ...


Meeting the 'grand challenge' of a sustainable water supply


Scientists and engineers must join together in a major new effort to educate the public and decision makers on a crisis in providing Earth's people with clean water that looms ahead in the 21st century. That's the focus of a comment article in the current edition of Chemical & Engineering ...


Driving magnesium micromotors with seawater


Scientists in the California have developed magnesium-based Janus micromotors that self-propel in seawater. Research shows how the micromotors can be used to capture and transport oil droplets from contaminated seawater, presenting a possible environmental application for the removal of oil ...


Stanford ultraresponsive magnetic nanoscavengers for next generation water purification

New synthetic cored nanoparticle could decontaminate tainted water and then be cleared with a magnet


Among its many talents, silver is an antibiotic. Titanium dioxide is known to glom on to certain heavy metals and pollutants. Yet other materials do the same for salt. In recent years, environmental engineers have sought to disinfect, depollute, and desalinate contaminated water using nanoscale ...
