A new hybrid layered perovskite featuring elusive spontaneous defect ordering has been found, report scientists. By introducing specific concentrations of thiocyanate ions into FAPbI3 (FA = formamidinium), they observed that ordered columnar defects appeared in the stacked crystalline layers, taking up one-third of the lattice space. These findings could pave the way to an innovative strategy for adjusting the properties of hybrid perovskites, leading to practical advances in optoelectronics and energy generation.

Researchers have synthesized triarylborane (TAB) compounds that exhibit unusual optical responses upon binding to certain anions. They also synthesized thin polymer films that incorporate the TAB and retain the sensing as well as the light emission properties of the TAB. This work is an important advance in plastic research and has applications in analyte sensing as well as electronic display technologies.

While there's no regulation in the U.S. for what's in organic shampoos, they tend to contain ingredients perceived as safe or environmentally friendly. However, these 'clean' shampoos separate and spoil faster than those made with synthetic stabilizers and preservatives. Now, researchers demonstrate that a simple process -- spinning organic shampoo at high speeds -- improved the final products' shelf lives and ability to clean hair.

New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.

Voids, or empty spaces, exist within matter at all scales, from the astronomical to the microscopic. In a new study, researchers used high-powered microscopy and mathematical theory to unveil nanoscale voids in three dimensions. This advancement is poised to improve the performance of many materials used in the home and in the chemical, energy and medical industries -- particularly in the area of filtration.

Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
