The latest review of the Government Chemist (GC) presents an account of LGCs analytical, advisory and strategic work for the Department of Trade and Industry (DTI) during 2004. An overview of the years achievements, the review shows significant growth in the role of the GC and the subsequent benefits for government, businesses and consumers.
The review focuses on the GCs three main responsibilities: its statutory referee function to provide evidence to resolve differences arising from analytical measurements made by businesses and regulatory enforcement bodies; its advisory role to government and industry on matters of policy, standards and regulation; and LGCs analytical and technological capabilities required to support the GC function effectively.
Dr John Marriott, Government Chemist and LGC’s Director of Analytical Technology, said: "It has been a busy year for the Government Chemist. As the referee analyst, we experienced a 79% increase in samples received under food and agriculture legislation, associated with the safety, authenticity or labelling of food products. One of the issues investigated concerned the amount of viable bacteria in probiotic food supplements that led to the product being removed from the market to be reformulated. Other challenges included the identification of irradiated food, the determination of mycotoxins in feeds, and the understanding of the variability in the determination of calcium concentration in fortified soya milk. On the advisory side, we have taken a lead on regulatory guidance for UK businesses during industry preparations for the EUs REACH chemical testing scheme."

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
