Coupled Solar Battery with 6.9 % Efficiency

Angewandte Chemie, 2023
AbstractSolar‐to‐electrochemical energy storage in solar batteries is an important solar utilization technology comparable to solar‐to‐electricity (solar cells) and solar‐to‐fuel (photocatalytic cells) conversion. Unlike the indirect approach of integrated solar flow batteries combining photoelectrodes with redox‐electrodes, coupled solar batteries ...

Efficient Simulation via Coupling

Probability in the Engineering and Informational Sciences, 1996
This paper is concerned with how coupling can be used to enhance the efficiency of a certain class of terminating simulations, in Markov process settings in which the stationary distribution is known. We are able to theoretically establish that our coupling-based estimator is often more efficient than the naive estimator.

Efficient solution of linearly coupled Lyapunov equations

Proceedings of 1994 American Control Conference - ACC '94, 1997
The authors develop a numerical algorithm for the efficient solution of sets of linearly coupled Lyapunov matrix equations which arise in numerical continuation methods for the design of robust and/or lower order control systems. This algorithm is a refinement of the algorithm due to \textit{S. Richter}, \textit{L. D. Davis} and \textit{E. G.

Efficient Coupling into Polymer Waveguides by Gratings

Applied Optics, 1997
Investigations of highly efficient grating couplers for polymer slab and strip waveguides fabricated by electron-beam lithography are reported. A maximum input efficiency of 67% is achieved. The electron-beam direct-writing technique allows one to replicate the original gratings into polymer substrates by embossing.

Coupling Efficiency of Helical Coil Hyperthermia Applications

IEEE Transactions on Biomedical Engineering, 1985
Experimental measurements have been made of the coupling efficiency of helical coil applicators operating under conditions simulating the regional hyperthermic heating of human extremities. We have found that for both saline and layered fat-muscle arm-size phantoms, the coupling efficiency ranged from 56 to 86 percent depending upon the specific coil ...

Energy Coupling Efficiency of Symbiotic Nitrogen Fixation

1977
The early evidence of a relationship between H2 metabolism and N2 fixation was reviewed by Wilson and Burris in 1947 (31). Phelps and Wilson in 1941 (20) reported the presence of a hydrogenase in the nodules of garden peas (Pisum sativum) that were inoculated with Rhizobium leguminosarum strain ONA 311. In 1956, however, Shug et al.

Increased coupling efficiency of fiber coupled modules by smile compensation

High-Power Diode Laser Technology XVII, 2019
A technique is experimentally demonstrated which allows for the compensation of the smile of a laser diode bar using a beam transformation system and a telescope array. The beam transformation system consists of a fast-axis collimator and an array of biconvex cylindrical lenses, which rotates each collimated beam by 90°.
