Complete monotonicity and inequalities related to generalized k-gamma and k-polygamma functions
Journal of Inequalities and Applications, 2020 In this paper, we prove new complete monotonicity properties of some functions related to generalized k-gamma and k-polygamma functions. Applications of the results yield various new inequalities. In the end, double inequalities are constructed involving

Advanced Materials, EarlyView.The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Adsorption and Separation by Flexible MOFs
Advanced Materials, EarlyView.Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,

Current Control of Spin Helicity and Nonreciprocal Charge Transport in a Multiferroic Conductor
Advanced Materials, EarlyView.A conducting multiferroic state of spin origin with both electronic polarity (P) and magnetization (M) can be controlled and detected by electric current in a high‐temperature helimagnet YMn6Sn6. The underlying concept is the coupling of the electric current with the toroidal moment T∼P×M$\bm{T}\sim \bm{P}\ensuremath{\times{}}\bm{M}$.

Advanced Materials, EarlyView.Organic photodiodes (OPDs) with low dark current and stable detectivity under light irradiation, air exposure, and heating are realized using a nanoparticle‐based Zn‐chelated PEIE (PEI‐Zn NP) electron transport layer. This formulation effectively suppresses photocurrent degradation and dark current increase, ensuring enhanced environmental stability ...
