Calcium channels are cell membrane proteins that play an important role in control the Ca ion flux through the membrane. In this study, the effect of external constant electric field on the dynamics of calcium ions in a L-type channel, located within a stochastically fluctuating medium, is modeled via the application of the molecular dynamics (MD) simulation method. The obtained results show th...

Generally speaking, seismoelectric modeling is a prospecting method based on seismic and electromagnetic waves, in which waves generated by a seismic source at the boundary of the two environments generate a relative fluid-solid motion formed as a result of antagonism between the elastic properties of the environment with the saturated fluid. This research has as its objective, a study of the e...

Abstract: In this study, using density functional theory and the SIESTA computationalcode, we investigate the electronic and optical properties of the armchair graphenenanoribbons and the armchair boron nitride nanoribbons of width 25 in the presence of atransverse external electric field. We have observed that in the absence of the electricfield, these structures are se...

We demonstrate a method to tune the carrier concentration of a high temperature superconductor over a wide range, using an applied electric field. Thin film devices were made in an electrical double layer transistor configuration utilizing an ionic liquid. In this way, the surface carrier density in La2ÿxSrxCuO4 films can be varied between 0.01 and 0.14 carriers per Cu atom with a resulting cha...

Monolayer mixtures of dihydrocholesterol and phospholipids at the air-water interface are used to model membranes containing cholesterol and phospholipids. Specific, stoichiometric interactions between cholesterol and some but not all phospholipids have been proposed to lead to the formation of condensed complexes. It is reported here that an externally applied electric field of the appropriate...

با پیشرفت تکنولوژی و افزایش فرکانس و کاهش ابعاد در بردهای الکترونیکی، تاثیرگذاری و تاثیرپذیری خطوط انتقال درون برد بر هم افزایش یافته است. برای اطلاع از میزان این تاثیر نیاز به محاسبه همشنوایی بین خطوط جدی می شود. همچنین برای اطلاع یافتن از اینکه برد حاصل استانداردهای emc را بر آورده می کند، باید میزان ولتاژ و جریان القایی در انتهای خطوط هنگامی که این برددر حضور میدان الکترومغناطیس خارجی قرار گ...

By varying the external electric field in density functional theory (DFT) calculations we have estimated the impact of the local electric field in the electric double layer on the oxygen reduction reaction (ORR). Potentially, including the local electric field could change adsorption energies and barriers substantially, thereby affecting the reaction mechanism predicted for ORR on different met...
