This paper presents a formal computational methodology to explain how the oxide in semiconductors degrades over time and the dependence of oxide degradation on voltage and temperature stresses. The effects of aging are modeled and quantified by modification of the gate-source capacitance value. The model output is validated using experimental results of a thermally aged power semiconductor device.

Direct heating of a metal-organic framework provides a simple, controllable way of effecting a covalent post-synthetic modification. Herein we report that an allyloxy-tagged zinc metal-organic framework undergoes a thermally-promoted aromatic Claisen rearrangement through which the framework connectivity and porosity are maintained.

Nitrate-containing compounds are considered as groundwater contaminants, the concentration of whichhas been growing in these resources during recent years. As a result, it seems necessary to use effectivemethods to remove nitrate from water and wastewater. Adsorption is generally considered moreeconomical in water treatment compared to other feasible a...

The paper presents a modification of capillary optical fibers fabrication method from an assembled glass preform. A change of dimensional proportions in the capillary optical fiber drawn from a single preform is allowed on-line via the control of overpressure and thermal conditions in the outflow meniscus which essentially lowers the manufacturing costs. These conditions are among the solutions...

The cr-polypeptides of Escherichia coli RNA polymerase are known to be chemically modified within 4 min after infection by bacteriophage Tq. This paper reports a crude system derived from T1-infected E. coli which will modify the cr-polypeptides of purified E. coli RNA polymerase in vitro. The product of this in vitro reaction is identical with the modified (Y found in viva ; it differs chemica...
