Through adsorption to metal surfaces while in solution, benzotriazole and tolyltriazole are able to inhibit corrosion on metal surfaces. Tolyltriazole is especially adept at creating this bond with copper and its alloys. Tolyltriazole is produced from ortho-toluenediamine (oDTA), which is a side stream in the production of toluene diisocyanate (TDI). In the recent weeks we... Read more »
Methane is produced by decomposing trash that can be used to produce electricity or heat. Currently, most landfills do not make enough methane for energy production to make it worthwhile. Therefore, these landfills burn (flare) the methane away. Russell Chinelli, Ph. D., a professor at The University of Texas at El Paso, invented a process... Read more »
Polyurethane, as many of you might already know, is extremely tough and corrosion-and-wear-resistant, which makes it a popular choice for a wide variety of applications. The only real downside is that the petroleum-based product isn’t as environmentally friendly as one would hope. But a new development from Washington State University is sure to change that....

An explosion and major fire erupted in China’s Fujian province Monday night, sending six people to the hospital, officials reported. State news agency Xinhua said 177 fire engines and more than 800 firefighters were sent to the scene. The plant, in the city of Zhangzhou, produces the chemical paraxylene (PX), which is the basic raw... Read more »
Superhydrophobic surfaces are found on duck feathers and lotus leaves that repels water. A Chinese group, led by Junqi Sun, from Jilin University has achieved the same superhydrophobicity. The surface heals itself. If the surface gets nicked, it allows water from the air to cause the molecules to fill back in and bring back the... Read more »
It’s called Continuous Liquid Interface Production (CLIP), and it could revolutionize 3D printing. Carbon3D, a privately-held Redwood City, California based company has created a process which can print three-dimensional objects as one piece instead of the layer by layer approach used now. Carbon3D uses photosensitive monomers which will polymerize when exposed to UV light, and... Read more »
