Jelly-like atmospheric particles resist chemical aging

(Phys.org)—Atmospheric chemists at the Harvard School of Engineering and Applied Sciences (SEAS) have found that when it comes to secondary organic material in the atmosphere, there are two distinct breeds: liquids and ...

Sunflowers inspire more efficient solar power system

(Phys.org) -- A field of young sunflowers will slowly rotate from east to west during the course of a sunny day, each leaf seeking out as much sunlight as possible as the sun moves across the sky through an adaptation called ...

Tiny airborne pollutants lead double life: study

University of British Columbia and Harvard researchers have provided visual evidence that atmospheric particles -- which are ubiquitous in the atmosphere, especially above densely populated areas -- separate into distinct ...

Putting the squeeze on planets outside our solar system

(PhysOrg.com) -- Using high-powered lasers, scientists at Lawrence Livermore National Laboratory and collaborators discovered that molten magnesium silicate undergoes a phase change in the liquid state, abruptly transforming ...

Cheap beads offer alternative solar-heating storage

A cheap material that can store heat energy collected from the sun during the day that can be released slowly over night has been developed by researchers in the India. The material based on paraffin wax and stearic acid ...

Better batteries through nanoscale 3D chemical imaging

Concerns over the finite availability of oil and the effect of greenhouse gases on climate have spurred intense efforts to develop electric-drive vehicles; the major barrier to successful commercialization being battery technology. ...

IBM scientists demonstrate computer memory breakthrough

(PhysOrg.com) -- For the first time, scientists at IBM Research have demonstrated that a relatively new memory technology, known as phase-change memory (PCM), can reliably store multiple data bits per cell over extended periods ...
