Application of Ibuprofen Sodium Dihydrate for Thermochemical Energy Storage
Advanced Functional Materials, EarlyView.Ibuprofen sodium dihydrate is introduced as a durable organic salt hydrate for low‐temperature thermochemical energy storage, operating within 60°C–110°C with high energy density. At the material level, it delivers ∼99.9% cycling efficiency over 150 cycles without deliquescence, enabled by a dual energy‐storage mechanism coupling dehydration and phase ...

Multi-part mirror for focusing diffuse light
Mechanical Engineering Journal, 2017 In the present study a multi-part mirror is developed for focusing only a scattered light effectively. The multipart mirror is composed from several elliptic mirrors. Several elliptic mirrors are installed on the surface of the multi-part mirror. Primary

Optics Express, 2008 A very general beam solution of the paraxial wave equation in elliptic cylindrical coordinates is presented. We call such a field an elliptic beam (EB). The complex amplitude of the EB is described by either the generalized Ince functions or the Whittaker-Hill functions and is characterized by four parameters that are complex in the most general ...

Twin Crystal Moiré Metasurfaces for Crossing Flat‐Band Transport
Advanced Functional Materials, EarlyView.This study introduces twin crystal moiré metasurfaces, breaking in‐plane symmetry to enable reconfigurable acoustic wave manipulation. By adjusting the twin angle and interlayer twist angle, various combinations of hyperbolic, flat bands, and elliptic states can be synthesized in the system.

Non-vanishing of Artin-twisted L-functions of elliptic curves [PDF]
, 2013 Let E be an elliptic curve and ρ an Artin representation, both defined over Q. Let p be a prime at which E has good reduction. We prove that there exists an infinite set of Dirichlet characters χ, ramified only at p, such that the Artin-twisted L-values ...

Preprint: Murmurations of Elliptic Curves
, 2022 We investigate the average value of the pth Dirichlet coefficients of elliptic curves for a prime p in a fixed conductor range with given rank. Plotting this average yields a striking oscillating pattern, the details of which vary with the rank. Based on

Existence of infinitely many solutions for nonlinear Neumann problems with indefinite coefficients
Electronic Journal of Differential Equations, 2014 We consider the nonlinear Neumann boundary-value problem $$\displaylines{ - \Delta u +u =a(x)| u | ^{p-2}u\quad \text{in }\Omega,\cr \frac{\partial u}{\partial \nu}=\lambda b(x)|u|^{q-2}u\quad \text{on } \partial\Omega, }$$ where $N\ge 3$ and ...
