Normally, only the ultraviolet (higher energy) component of the solar spectrum is usable for the photo-catalytic electrolysis of water into hydrogen and oxygen, which takes place in photochemical cells with an anode made of single-crystalline, rutile-type titanium oxide and a platinum electrode. Now, water can be photolyzed into H2 and O2...

Of all known materials, carbon nanotubes (CNTs) have the highest thermal conductivity and mechanical strength as well as the ability to withstand the highest electric-current density, making them an attractive material for electric wiring, heat dissipation, field electron emission, and other applications. And graphene — a two-dimensional hexagonal lattice of carbon atoms — has become attractive...

Polyglycolic acid (PGA) has good properties: a very high gas impermeability, even under 80% humidity; biodegrability; high mechanical strength; and good moldability, which makes it a promising polymer for applications such as medical devices and barrier films. But up to now, it has been difficult to make large quantities of the material. Kureha Corp. (Tokyo, Japan; edlinks.che.com/7371-536) has developed a...

The Seebeck effect — the direct conversion of a temperature difference to electricity — is responsible for the operation of thermocouples. But taking advantage of this phenomenon to make electricity from waste heat in so-called thermoelectric (TE) devices has been hindered by the high cost or toxicity of common TE materials, such as lead-tellurium or cobalt-antimony. And up to now, production...

A durable flowmeter for remote applications outdoors A thermal-dispersion, mass-flow sensing technology, the ST50 Flow Meter Series (photo) boasts ±1% accuracy (repeatability ±0.5%) for 2 – 24-in. line sizes and a built-in temperature compensation for reliable measurement over a 40 – 100°F temperature range. There is almost no pressure-drop, according to the firm. The ST50...

Hitachi Zosen Corp. (Hitz; Tokyo, Japan; edlinks.che.com/7369-531) is commercializing a new membrane for a hybrid-distillation system (HDS) that is especially suitable for dehydrating ethanol and isopropanol. The HDS can produce 99.7 vol.% ethanol from ethanol-water mixtures with 10 vol.% H2O at a dehydration rate of 50 kg/m2/h/atm (at 130°C), which is more than two times higher than conventional...

Daihatsu Motor Co., Ltd. (Osaka, Japan; edlinks.che.com/7369-532) has designed a fuel cell for powering automobiles, using nickel and cobalt for the electrodes (instead of conventional platinum and carbon), and hydrazine hydrate (N 2H4. H2O) as its fuel (instead of hydrogen). Although hydrazine is a hazardous material, the company says the hazard level is about the same as gasoline. And unlike H2, which...

The amount of crude oil remaining in depleted oil fields has been estimated to be about 50 – 80% of the total estimated oil reserves. In the past, CO2 has been injected into such wells for enhanced-oil recovery — a technique that displaces the oil and stores the greenhouse gas. Now, a completely different approach to monetizing the carbon is being considered by Inpex Holdings Inc. (Tokyo...

Technology to copolymerize carbon dioxide and propylene oxide (PO) was first discovered in 1960s, but has not been commercialized due to the formation of cyclic propylene carbonate (CPC) by a “back-biting” reaction, which leads to the formation of unstable, low-molecular-weight copolymers. This limitation has essentially been eliminated, thanks to a new catalyst developed by Professor Kyoko...
