Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Frechet differentiability of the metric projection operator in Banach spaces [PDF]

open access: yesarXiv
In this paper, we prove Frechet differentiability of the metric projection operator onto closed balls, closed and convex cylinders and positives cones in uniformly convex and uniformly smooth Banach spaces. With respect to these closed and convex subsets, we find the exact expressions for Frechet derivatives and Gateaux directional derivatives of the ...

Revisiting Membrane‐Free Zn–Mn Redox Flow Batteries: An Innovative Universal Aspartic Acid Additive for Superior Stability

open access: yesAdvanced Energy Materials, EarlyView.
An all‐aqueous, membrane‐free Zn–Mn redox flow battery utilizing deposition chemistry can be a promising alternative to conventional aqueous redox flow systems. Since it uses a combined electrolyte in which the catholyte and anolyte are mixed, issues affecting both the cathode and anode can be addressed simultaneously with the simple addition of an ...

Coal rock image recognition method based on improved CLBP and receptive field theory

open access: yesDeep Underground Science and Engineering, Volume 1, Issue 2, Page 165-173, December 2022., 2022
In view of the evident differences between coal and rock in visual attributes such as color, gloss, and texture, the complete local binary pattern (CLBP) image feature descriptor is introduced for coal and rock image recognition, and the original algorithm oversimplifies local texture features by ignoring imaging information from higher‐order pixels ...

Regularization proximal point algorithm for finding a common fixed point of a finite family of nonexpansive mappings in Banach spaces

open access: yesFixed Point Theory and Applications, 2011
We study the strong convergence of a regularization proximal point algorithm for finding a common fixed point of a finite family of nonexpansive mappings in a uniformly convex and uniformly smooth Banach space.

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

Boosting Ambient Hydrogen Storage in Graphene via Structural and Functional Designs: A Review

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The advanced progress of graphene‐based hydrogen storage via structural engineering, functional modification, and their synergy is systematically reviewed. Each strategy is further classified based on the function mechanism difference, with representative works introduced.

BERGMANN AND HARDY SPACES AND CONJUGATE OF THEM

open access: yesAdvanced Engineering Research, 2012
It is proved that  space is strongly notmed, and  is neither strongly notmed, nor uniformly convex. A standard form of the linear functionals over  space and over metric spaces of  0 < p £ 1, is determined.
