When organic chemists identify a useful chemical compound — a new drug, for instance — it’s up to chemical engineers to determine how to mass-produce it.

There could be 100 different sequences of reactions that yield the same end product. But some of them use cheaper reagents and lower temperatures than others, and perhaps most importantly, some are much easier to run continuously, with technicians occasionally topping up reagents in different reaction chambers.

The cellulose-based synthetic fiber viscose is a popular fabric of choice for countless apparel companies, and is often touted as a sustainable material. But this textile, often sourced from wood pulp, has generated more than its fair share of controversy over the years. Some high-profile designers, notably Stella McCartney, have pledged to source material that can only be traced to responsibly managed forests; McCartney herself has striven to raise awareness about the links viscose has to deforestation and pollution.

Dr. Ewa Burwicz-Galerne from the GEOMAR Helmholtz Center for Ocean Research Kiel has been awarded during the ninth International Gas Hydrate Conference (ICGH9) in Denver (Colorado, USA) for the world's best PhD thesis in the field of natural gas hydrate research in the past three years. For her thesis, the geologist has developed some of the most complex numerical models of gas hydrates and has gained new insights into their development. The latest study recently was published in the international journal Geochemistry Geophysics, Geosystems.

For upcoming climate model studies, scientists can use a new, significantly improved data set for solar forcing. An international science team led by the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Instituto de Astrofísica de Andalucía (CSIC) in Granada (Spain) has now published the details of the new reconstruction of this reference dataset in the journal Geoscientific Model Development. A significantly enhanced influence of solar cycle effects is expected, particularly in the stratosphere.
