An experimental study of a hemi-spherical solar collector under Egyptian climate
Case Studies in Thermal Engineering, 2021 Traditional flat plate collectors have shown, under many investigations, low system operating efficiency, which prompted the idea of designing new solar collectors operating with higher efficiency.

Metal-Free Polymer-Based Current Collector for High Energy Density Lithium-Metal Batteries. [PDF]
SmallThe energy density of lithium-metal batteries (LMBs) relies substantially on the thickness of the lithium-metal anode. However, a bare, thin lithium foil electrode is vulnerable to fragmentation due to the inhomogeneity of the lithium stripping/plating ...

Flexible and Lightweight Lithium-Ion Batteries Based on Cellulose Nanofibrils and Carbon Fibers
Batteries, 2018 Flexible, low-weight electrodes with integrated current collectors based on chopped polyacrylonitrile carbon fibers (CF) were produced using an easy, aqueous fabrication process, where only 4 wt% of TEMPO-oxidized cellulose nanofibrils (CNF) were used as

Contact interaction “brush – collector” and working efficiency of locomotive traction electric motor
MATEC Web of Conferences, 2018 The working efficiency of locomotive traction electric motors of direct current is largely determined by the reliability of the collector-brush assembly. The paper presents the results of simulation of the contact interaction “brush-collector” in the

Analytical Base-Collector Heterojunction Capacitance Model Including Collector Current Effects
, 1989 The base‐collector heterojunction space‐charge‐region capacitance of double heterojunction bipolar transistors is treated. This capacitance cannot be modeled as the conventional heterojunction depletion capacitance because it is heavily influenced by the

Sulfur cathodes with carbon current collector for Li-S cells
, 2022 S.A996-A1002Li-S cells have a low voltage (about 2.1 V), but their potentially high energy density (200-500 Wh/kg) makes them a promising system for next generation batteries. To obtain high energy densities on cell level, the weight fraction and load of

Current-dependent collector resistance of the bipolar transistor in quasi-saturation
, 1998 The current-dependent collector resistance of the bipolar transistor in quasi-saturation has been modelled. The analytical collector resistance model is derived from device physics. The MEDICI simulation is employed to justify the assumptions used in the
