Scientists have developed a molecular bonding method that could make flexible organic solar cells more efficient and durable, addressing two obstacles that have limited their wider use. The new design achieved 20.4% power conversion efficiency in small laboratory cells and 18.8% active-area…
Chemists have tracked the fleeting intermediates in the natural synthesis of penicillin using ultrashort x-ray pulses. The research could usher in improvements in ring-forming reactions on useful intermediates for the pharmaceutical industry or aid enzyme engineering. Animated molecular movie of…
A materials study found that hierarchically structured, silver-decorated polycarbonate combined a water contact angle of about 156.7° with an enhanced Rhodamine 6G SERS signal. A materials study reported in the Journal of Materials Science found that hierarchically structuring a commercially available polycarbonate…
Stainless steel is widely used for its impressive corrosion resistance, but it is not invincible. In environments containing chloride ions, such as seawater, pitting corrosion can occur. These pits often start at tiny particles called inclusions embedded in the steel.
University of Warwick physicists discover presence of a special ferroelectric texture that mirrors the spin crystal phase (checkerboard-like symmetry) in ferromagnets. Bulk ferroelectric crystals have been used for many years in a range of technologies including sonar, audio transducers, and…
By targeting vascular lesions, the newly developed nanomedicine offers a new method for healing the damage caused by vascular disease. Vascular diseases like atherosclerosis can lead to serious complications, like heart attack or stroke. But many treatments for these diseases…

A research team led by Tohoku University investigated 13 different silicate glass compositions to understand how their thermal properties influence heat conduction. Their findings revealed that the speed of sound through glass plays the dominant role in determining its thermal conductivity.
Organic molecules have produced an electronic behavior that researchers have struggled to engineer in molecular materials. Scientists assembled triptycene-based molecules into a rare two-dimensional lattice and detected quantum states confined to its edges. The finding could widen the options for…
