It is assumed that the resistance to transverse flow comes from the narrow gaps formed between the fibers. As f→fc=π4, one would simply have the following expression, (7.4)Kl′(f)≃16(π4−f)5/29π7/2, which matches the general critical form with the critical index for permeabili...
For example, when graphene sheets are used as conductive channel, cracks represent a reduction of the effective area through which the current can flow and, therefore, an increase of the electronica resistance. Despite this defect may alter the performance of the device, unless the channel is ...
Intermetallic alloys possess exceptional strength, thermal stability, and creep resistance, making them promising for structural applications at high temperatures, such as in the aerospace and nuclear industries1. However, the poor plasticity of traditional intermetallic alloys at low temperatures due to a...
The geometry of the device is the same as the experiments and the material of the channel is set to metallic material with similar conductivity as CGT. b Angle-dependent channel resistance (Rch) and Rnl as the magnetic field rotated in xz plane (γ). The inset shows the relevance between...
Since in fuel cells (FCs) the multifunctional layers play an important role during the energy conversion process, and such layers consist of porous material, the ohmic resistance of porous materials represents a crucial characteristic to be studied to predict the internal ohmic losses. The purpose ...
His research interests mainly focus on high-performance steels, metallic glasses, high-entropy materials and computational material science, etc. Suihe Jiang is now a full professor of the State Key Laboratory for Advanced Metals and Materials, USTB and specializes in ultrahigh strength steels and ...
In the present context, however, we have in mind solid junctions of intersecting fibers that offer elastic resistance to relative fiber shear and rotation. This seems to us to furnish a faithful representation of the actual situation in a manufactured fibrous metamaterial [1, 4]. In this case ...

Transistors in series are slower than transistors in parallel, just as resistors in series have more resistance than resistors in parallel. Moreover, pMOS transistors are slower than nMOS transistors because holes cannot move around the silicon lattice as fast as electrons. Therefore, the parallel ...
The perovskite/CIGS losses were attributed to the reduced shunt resistance from the CIGS bottom cell and contact layers, as well as modest decrease in luminescence from the CIGS. Additionally, it appeared to have negligible effects on the perovskite bulk, with an increase in photoluminescence due ...
