A process from Dow Water & Process Solutions (DW&PS; Edina, Minn.; www.dowwaterandprocess.com) uses a unique adsorbent resin to improve the taste of orange juice. Amberlite FPX66 is a macroreticular, non-functionalized adsorbent resin with a pore structure designed to capture a variety of target molecules. In the case of orange juice, this resin...

Lactose has been widely used as a pharmaceutical excipient, where the size and morphology of the particles of lactose significantly affect the functionality of the resultant drug product. Lactose particles produced by various methods exhibit various morphologies, such as spherical amorphous particles, or lactose crystals with tomahawk or sharp and fine morphology. To date, however, there is no report in...

A continuous fermentation process for making biologically derived butanol from a variety of sugar feedstocks is operating at what developers call “lab-pilot” scale, producing 2.5 liters per day. Engineering studies conducted by the research team forecast that it could be produced for the same cost as existing sugar-based bioethanol processes. The technology developer, Optinol Inc. (San...

Cement manufacturing is a major source of greenhouse gas emissions due to two factors: carbon dioxide is released when calcium carbonate calcines to lime (CaO) in the cement manufacturing process; and cement kilns are operated at temperatures of 1,500°C, which requires significant fuel consumption. Cement is the agent that binds sand and crushed rock together to form concrete. Solidia Technologies...

The selective, one-step biocatalytic hydroxylation of benzene to phenol — at ambient pressure and temperature — has been demonstrated by professors Yoshihito Watanabe and Osamu Shoji at Nagoya University (Nagoya, Japan; bioinorg.chem.nagoya-u.ac.jp). The achievement was made using a wild-type of Cytochrome P450BM3 with the simple addition of perfluorinated compounds (PFCs) as decoy molecules...

Although the inactivation of bacteria by high-power ultrasound has been extensively studied, the relationship between the effectiveness of ultrasound to inactivate bacteria and their physico-chemical properties is not yet well understood, says Muthupandian Ashokkumar, professor at the University of Melbourne (Australia; www.unimelb.edu.au). Hence, a team from the University of Auckland (New Zealand...

Many investigations are ongoing to achieve ammonia synthesis at energy-saving mild conditions instead of the high temperatures and pressures (500°C, 300 atm) required by the commonly used Haber-Bosch process, which consumes more than 1% of the world’s power production. Now, Zhamin Hou, Takanori Shima and...

The petroleum refining sector in India plays a vital role in the country’s industrial development and provides a major source to meet India’s energy requirements. Today, the refining sector satisfies about 30% of the total energy demand of India [ 1]. As of April 1, 2013, the total installed capacity of Indian refineries was 215 million metric tons per year (million m.t./yr), of which 80...
