Drift-dominated conduction within an Ohmic medium

Abstract

Drift-dominated charge transport within an Ohmic medium is analyzed using the method of characteristics to convert the governing partial differential equations into a set of ordinary differential equations. As for earlier work within a lossless medium, the analysis is generalized to allow any initial and boundary conditions and any terminal constraint or excitation. For imposed currents the equations are exactly integrable, while for imposed voltages, the equations are easily integrated using the Runge-Kutta method of numerical integration. Special cases examined are the charging transients for space-charge-limited conduction for step current and step voltage excitations from rest and the discharging transients for systems in the dc steady state for which the excitation is instantaneously open or short circuited.

In Silico Search for Boron‐Beryllium Dative Bond

“…Thus, it is expected that the compound 1 may act as electron pair donor, or Lewis base . In recent years, stable singlet carbenes have proven to be powerful compounds to stabilize highly reactive main group species …”

“…Thus, we envisioned that a dative bond between B and Be may be possible to form where the B center in compound L will act like a donor (Scheme ) while the Be center in BeCl 2 will act like an acceptor. The choice of the compounds L is guided by the fact that different types of carbenes are now known experimentally which have proven to stabilize various main group elements in their lower oxidation states …”

Recent Advances in the Schiff Bases and N‐Heterocyclic Carbenes as Ligands in the Cross‐Coupling Reactions: A Comprehensive Review

“…In the last two decades, NHCs have been leading the world of catalysis in an unprecedented manner. NHC–transition metal complexes have been extensively used as catalysts for various organic reactions such as Suzuki, Heck, Stille, Sonogashira, Kumada, hydrogenation, alkene metathesis, trifluoromethylations, selective hydrodefluorination, cyclopropanation, and enantioselective synthesis of organofluorine compounds . Thus, for the researchers, NHC ligands have become of vital interest to understand the fundamental reasons behind their catalytic behavior.…”

Imidazol(in)ium‐2‐Carboxylates as Efficient Precursors to N‐Heterocyclic Carbene Complexes of Copper and Silver

“…To the best of our knowledge, the application of imidazol(in)ium‐2‐carboxylates as intermediates for the synthesis of [CuCl(NHC)] and [AgCl(NHC)] complexes is unknown . For the application of NHC‐CO 2 adducts as substrates in the synthesis of NHC complexes with Rh, Ir, Ru, Pd, and Ti, see a comprehensive review in .…”
