Abstract
Die Induktionsphase der Hydrochlorierung von metallurgischem Silicium wurde mittels einer oszillieren Mikrowaage untersucht. Es konnte gezeigt werden, dass während dieser Phase neben der Adsorption von HCl auf der Silicium‐Oberfläche die Diffusion des Chlors in die Bulk‐Phase stattfindet. Die Dauer der Induktionsphase kann mittels der Temperatur und HCl‐Konzentration beeinflusst werden.
The induction phase of hydrochlorination of metallurgical silicon has been investigated with an oscillating microbalance. It could be shown that in addition to the adsorption of HCl on the silicon surface during this phase the diffusion of chlorine in the bulk phase occurred. The duration of the induction phase can be influenced by the temperature and concentration of HCl.
Das Phänomen der Induktionsphase bei der Hydrochlorierung von Silicium ist bisher nur unzureichend charakterisiert worden. Mithilfe einer oszillierenden Mikrowaage wurde diese Reaktion untersucht. Mit den gewonnen Ergebnissen können neue Rückschlüsse über das Zündverhalten gewonnen werden.

Vesicle‐Mediated Growth of Tubular Branches and Centimeter‐Long Microtubes from a Single Molecule
Abstract The mechanism by which small molecules assemble into microscale tubular structures in aqueous solution remains poorly understood, particularly when the initial building blocks are non‐amphiphilic molecules and no surfactant is used. It is here shown how a subnanometric molecule ... more
The image illustrates a natural phenomenon of droplet formation caused by the condensation of vapor on a nonwettable surface at temperature below the dew point. Real‐time observing the light scattered from the droplets may lead to a new mechanism for vapor sensing. However, the dew point ... more
NO is a key vasodilator in mammalian cardiovascular systems and has been shown to sensitize tissue to γ‐radiation. However, photochemical NO precursors that can be activated by these NIR wavelengths are extremely limited. G. D. Stucky, D. Zhao, P. C. Ford, F. Zhang and co‐workers have ad ... more
Bioengineers Succeed in Producing Plastic Without the use of Fossil Fuels
A team of pioneering South Korean scientists have succeeded in producing the polymers used for everyday plastics through bioengineering, rather than through the use of fossil fuel based chemicals. This groundbreaking research, which may now allow for the production of environmentally consci ... more
In the past, restoration of paintings and other old artwork often involved application of acrylic resins to consolidate and protect them. One of the most important tasks for modern restorers is thus to remove these layers, because it turns out that acrylic resins not only drastically change ... more
Is trash the solution to tackling climate change?
Converting the trash that fills the world's landfills into biofuel may be the answer to both the growing energy crisis and to tackling carbon emissions, claim scientists in Singapore and Switzerland. New research published in Global Change Biology: Bioenergy, reveals how replacing gasoline ... more
