Advanced Science, 2021 It remains a daunting task to quantify the configurational entropy of a material from atom‐revolved electron microscopy images and correlate the results with the material's lattice thermal conductivity, which strides across statics, dynamics, and thermal

On Crossed Product Rings Over p.q.-Baer and Quasi-Baer Rings
International Journal of Analysis and Applications, 2023 In this paper, we consider a ring R and a monoid M equipped with a twisting map f: M×M -> U(R) and an action map ω: M -> Aut(R). The main objective of our study is to investigate the conditions under which the crossed product structure R⋊M is p.q.-Baer ...

Null-homotopic knots have Property R
Mathematical Proceedings of the Cambridge Philosophical Society, 2023 AbstractWe prove that if K is a nontrivial null-homotopic knot in a closed oriented 3–manfiold Y such that $Y-K$ does not have an $S^1\times S^2$ summand, then the zero surgery on K does not have an $S^1\times S^2$ summand. This generalises a result of Hom and Lidman, who proved the case when Y is an irreducible rational homology sphere.

A High-Performance Supercapacitor Based on Nitrogen-Doped Porous Carbon Derived from Cycas Leaves
International Journal of Electrochemical Science, 2019 In this work, we proposed a new way to synthesize nitrogen-doped porous carbon materials. Nitrogen-doped porous carbon materials were prepared using cycas leaves as the carbon source and urea as the nitrogen source.

A note on a generalization of injective modules
Karpatsʹkì Matematičnì Publìkacìï, 2020 As a proper generalization of injective modules in term of supplements, we say that a module $M$ has the property (ME) if, whenever $M\subseteq N$, $M$ has a supplement $K$ in $N$, where $K$ has a mutual supplement in $N$. In this study, we obtain that $(

Porous Carbon Electrode Derived from Waste Wine Industry for Supercapacitors
International Journal of Electrochemical Science, 2019 Using porous carbon derived from waste biomass as electrode material for supercapacitors is a hot topic. It reuses waste at low cost. In this work, JZn-850 is prepared from waste wine industry by treatment with ZnCl2.

Homology spheres and property R
Proceedings of the American Mathematical Society, 2020 We present infinitely many homology spheres which contain two distinct knots whose 0 0 -surgeries are S 1 × S 2 S^1 \times S^2 . This resolves a question posed by Kirby and Melvin in 1978 1978 .
