Catilin Receives Renewable Energy Award for Pilot Plant

... biodiesel catalyst: Catilin's T300 Biodiesel Catalyst. Biodiesel is commonly produced using a homogeneous (liquid) catalyst, such as sodium hydroxide or sodium methylate. These catalysts require excessive amounts of water, energy, toxic chemicals, and equipment to produce the biodiesel and ...

New nanocluster to boost thin films for semiconductors

... semiconductor capabilities for large-area applications. The key to a "bottom-up" production of possibly the first heterometallic gallium-indium hydroxide nanocluster was the substitution of nitroso-butylamine as an additive in place of nitrosobenzene. The substitute was identified during a ...

Fundamentals of Fermentation: Techniques For Benchtop Fermentors

... clockwise rotation. Take note that silicon tubing should not be used with hydrochloric acid (HCL), sulfuric acid (H 2 SO 4 ) or sodium hydroxide solutions since this material deteriorates rapidly when in contact with these solutions another reason for avoiding HCL is that ...

High Yield Protein Production from Pichia pastoris Yeast: A Protocol for Benchtop Fermentation

... 2) plus 4.4 mL/L trace metal solution (4). The temperature was controlled at 30C. The dissolved oxygen was set at 30% and pH is at 5.0. Ammonium hydroxide solution (30%) was used as the base solution to adjust the pH. After 20 hours of batch culture, the optical density (OD) reaches 42. The glycerol ...
