Featured Articles Ultrasound Generates Intense Mechanoluminescence, Researchers Report
Many people know that if you bite or break a Wint-O-Green Lifesaver in the dark, you will see a spark of green light. That light is called mechanoluminescence, also known as triboluminescence.
Typically, mechanoluminescence is generated by simply grinding, cleaving, biting, or scratching a material, and this process produces a very dim light.
Chemistry professor Kenneth S. Suslick and graduate student Nathan C. Eddingsaas at the University of Illinois at Urbana-Champaign have used high-intensity ultrasound in liquid slurries of sugar and other organic crystals to create mechanoluminescence up to 1,000 times more intense than from grinding. continue
CARON INTRODUCES HEATED INCUBATOR/ENVIRONMENTAL CHAMBER
CARON's new Heated Incubator/Environmental Chamber provides a high
volume solution for applications requiring precision temperature control,
such as elevated temperature studies, shelf life testing, and basic
clinical studies. Temperature range of 5°C above ambient to 60°C is
controlled with a drift-resistant RTD that maximizes temperature
stability over time.

Coal-to-Diesel Breakthrough Could Cut Oil Imports
Professor Alan Goldman and his Rutgers team in collaboration with researchers at the University of North Carolina at Chapel Hill have developed a way to convert carbon sources, such as coal, to diesel fuel.
Goldman explained that the breakthrough technology employs a pair of catalytic chemical reactions that operate in tandem, one of which captured the 2005 Nobel Prize in Chemistry. This dynamic chemical duo revamps the Fischer-Tropsch (FT) process for generating synthetic petroleum substitutes, invented in 1920 but never developed to the point of becoming commercially viable for coal conversion. continue Nature's Process for Nitrogen Fixation Caught in Action
Nitrogen gas is converted to ammonia fertilizer by a chemical process that involves high temperature and high pressure. Nature does the same thing at ambient temperature and pressure. The process, called nitrogen fixation, is essential to life as it provides nutrients to plant life.
A research team from Utah State University, Virginia Tech, and Northwestern University asked whether the biological process, carried out by microbes that contain the enzyme nitrogenase, follows the same pathway as recently reported chemical methods. Their research method resulted in the ability to witness steps in the biological process that enables some microorganisms to convert atmospheric nitrogen to nutrients.continue

New Technique Breaks Nanometer Barrier in X-Ray Microscopy A new X-ray microscopy technique that observes molecular-scale features less than a nanometer in height has been developed by scientists at the U.S. Department of Energy's Argonne National Laboratory in collaboration with Xradia, Inc. By combining X-ray reflection with high-resolution X-ray microscopy, scientists can now study interactions at the nanometer-scale, where materials often exhibit new properties. A better understanding of interactions at the nanoscale promises to help cure the sick, protect the environment and make the nation more secure. continue
NEW! White Paper on Best Practices for Managing Lab Chemical Inventory
ChemSW, Inc.’s latest white paper details best practices in chemical inventory management, providing insights to ensure system adoption and successful incorporation into lab processes. Reasons why systems fail and why they succeed are examined, as well as the true costs associated with chemical inventory management and cost savings that result when such a system is optimized for maximum effectiveness.

Fast & Convenient Rotavap Vacuum Control from BrandTech Scientific.
Vacuum control determines the speed and productivity of your rotary
evaporator. So why control vacuum conditions manually, instead of
with advanced electronics? Don’t you have more creative ways to use
all that education? VACUUBRAND® VARIO™ self-regulating vacuum
continually optimizes vacuum conditions in your rotary evaporator
without babysitting or programming. It dramatically reduces bumping
and foaming, and shortens process times by up to 30% compared with
conventional electronic controls.
