In an advance toward glass that remains clear under the harshest of conditions, scientists are reporting development of a new water-repellant coating that resists both fogging and frosting. Their research on the coating, which could have uses ranging from automobile windshields to camera lenses, appears in the journal ACS Nano.
Michael F. Rubner, Robert E. Cohen and colleagues point out that anti-fogging coatings that absorb water have been the focus of attention lately because of their ability to reduce light scattering and the resultant distortion caused by condensation. However, under extreme fogging conditions, these surfaces may frost and become foggy. They set out to make a better coating to withstand the aggressive conditions.
Their report describes development and testing of a new coating that rapidly absorbs water molecules that cannot freeze in the coating. At the same time, the coating has a water-repelling or hydrophobic effect to larger water droplets. The hydrophobic character means that water droplets do not spread extensively on the coating but essentially remain as flattened droplets.
A method smartphones use to simplify images when storage space is limited could help answer tough chemistry problems. In a report appearing in ACS Central Science, researchers apply this technique, called compressed, or compressive sensing, to quickly and efficiently address central questio ... more
Lithium-ion batteries have enabled many of today's electronics, from portable gadgets to electric cars. But much to the frustration of consumers, none of these batteries last long without a recharge. Now scientists report in the journal ACS Nano the development of a new, "green" way to boos ... more
The versatility of palm oil has led to its use in not just food products but also in everyday goods from lipstick to laundry detergent. But its utility has resulted in the destruction of Southeast Asian rain forests that are the primary source of the oil. An article in Chemical & Engineerin ... more
