Professor Kenichoro Itami and his group at Nagoya University (synth.chem. nagoya-u.ac.jp) have synthesized a cage-type carbon nano-molecule, Carbon Nano-cage, composed of 20 condensed benzene rings — C120H78. The group used a procedure it developed four years ago to synthesize carbon…
Several drug delivery systems have been studied involving the encapsulation of molecules in a suitable structure and their transport through the human body. In particular, polymersomes — tiny hollow spheres that enclose a solution — formed using synthetic block copolymers…
Fans and blowers are common in air-handling and movement systems used in the chemical process industries (CPI). Two major uses of fans and blowers are in pneumatic conveying systems and in ventilation and air-pollution-control systems. Powering fans and blowers can…
Inorganic acids play a major role in the chemical process industries (CPI). They are used as raw materials, catalysts or finishing and pH control agents in the manufacture of a wide range of chemical products, from fertilizers to detergents, and…
Small chemical reactors offer a number of benefits compared to large reactors, such as better heat transfer and mixing. While small batch vessels are impractical at the industrial scale, continuous flow reactors can provide the benefits of small physical size…
The QVF Supra-Line is compatible with two proven flange systems — the QVF/WPR2002 and the Schott/KF systems — and thus reduces the number of technically equivalent components required while providing the user with increased safety. The Supra-Line extends the allowable…
Two new diameters extend the diversity of this company’s modular-pipework system for handling bulk goods, dust extraction and exhaust air. Introducing these two new nominal diameters of 280 and 315 mm adds an extra 250 products to the range, which…
The new E-Series Plastic AODD (air-operated double diaphragm) pumps feature no mechanical seals or packing, thereby eliminating a critical leak point. Instead, these pumps have a stainless-steel containment ring that creates consistent high-torque compression all the way around the ring,…
Though times are changing, many of the traditional challenges associated with running a chemical processing plant remain the same. For years processors have been asking for leak-proof, high-performance valves, but it is only recently that valve manufacturers are employing new…
Sparging refers to the process of injecting a gas through a diffuser into a liquid phase. It is used in both physical and chemical process applications. In physical process applications, the gas is used to either dissolve gas into liquid…
