91 Peptide 46 preferentially interacts with Hg2 + by forming a complex in which two cyclopeptide rings bind to one metal ion. Complex formation is reported by the change of the fluorescence of the tryptophane residue. It should also be mentioned that the SH groups in cyclopeptides 47a,b ...
Naturaldiamonds are formeddeep underground — typically 100 miles or so below the Earth's surface in a layer called the upper mantle — and brought to the surface by volcanic eruptions. Certain conditions are required for diamonds to form, namely intense pressure and heat. Temperatures can range ...
When two rectifiers are combined in a back-to-back configuration, a transistor can be formed. The most common electrical rectifiers are based on the use of the junction. Its rectification can be explained by the diffusion and drift of two kinds of carriers at the interface of the junction. ...
correspond to the spontaneous creation and annihilation of a single-ion bound-state through a net change of two units of angular momentum, implying that the relevant interaction vertices are mediated by the anisotropic,spin-non-conservingtermJ±±Si+Sj+, see vertices with a gray background in Fi...
(purple region) is created by a RF antenna, and iodine ions (I+, I2+and I2+) are accelerated by a set of grids. A cathode emits electrons (e−) to neutralize the ion beam. Waste heat is conducted towards the iodine tank and structural frame (solid blue arrows) or radiated away ...
formed and destroyed through sandbuildup and erosion. They are home to over six million people, who face repeateddisplacement from flooding and erosion--which may be getting worse because ofclimate change-and a range of health risks, including poor nutrition, malaria (疟疾) andother water-borne...

Highly doped or emitter regions in silicon solar cells can be formed by thermal diffusion, laser doping or ion implantation. They are commonly characterized by a saturation current density parameter, Joe, that encompasses recombination within the bulk of the thin heavily doped region as well as the...
Prediction of the stereochemistry is of equal importance, since up to four new stereogenic centers can be formed of the cycloaddition. In numerous reactions, however, a sufficient control of stereoselectivity has proven to be quite difficult. For instance, the addition of acyclic alkenes to cyclopent...
