Critical-Point-Dried, Porous, and Safer Aramid Nanofiber Separator for High-Performance Durable Lithium-Ion Batteries

open access: yes
Ionically conducting, porous separator membranes with submicrometer size pores play an important role in governing the outcome of lithium-ion batteries (LIBs) in terms of life, safety, and effective transport of ions. Though the polyolefin membranes have

The Assessment of Level of Flash Floods Threat of Urbanised Areas

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Flash floods (or torrential rain flooding) is another type of flood hazard which has caused casualties and significant property damages. A methodology for identification of urban areas, which can potentially be burdened by that type of flood hazard, was ...

Relative Critical Points [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
Relative equilibria of Lagrangian and Hamiltonian systems with symmetry are critical points of appropriate scalar functions parametrized by the Lie algebra (or its dual) of the symmetry group. Setting aside the structures - symplectic, Poisson, or variational - generating dynamical systems from such functions highlights the common features of their ...

Critical point drying of suspended structures after wet etch

open access: yes, 2020
In this report I monitor a full successful cycle of critical point drying (CPD) run for drying MEMS sensors after wet release using KOH etching. The pressure and temperature of the CPD tool (Tousimis) is monitored during the process and plotted in a P-T ...

Existence results for a sublinear second order Dirichlet boundary value problem on the half-line [PDF]

open access: yesOpuscula Mathematica, 2020
In this paper we study the existence of nontrivial solutions for a boundary value problem on the half-line, where the nonlinear term is sublinear, by using Ekeland's variational principle and critical point theory.

Spectrum Curves for Sturm–Liouville Problem with Integral Boundary Condition

open access: yesMathematical Modelling and Analysis, 2015
We consider Sturm–Liouville problem with one integral type nonlocal boundary condition depending on three parameters γ (multiplier in nonlocal condition), ξ1, ξ2 ([ξ1, ξ2] is a domain of integration).

Fractional Calculus Extension of the Kinetic Theory of Fluids: Molecular Models of Transport within and between Phases

open access: yesMathematics, 2022
The application of fractional calculus in the field of kinetic theory begins with questions raised by Bernoulli, Clausius, and Maxwell about the motion of molecules in gases and liquids.

On the existence of three solutions for quasilinear elliptic problem [PDF]

open access: yesOpuscula Mathematica, 2012
We consider a quasilinear elliptic problem of the type \(-\Delta_p u = \lambda (f(u)+\mu g(u))\) in \(\Omega\), \(u|_{\partial \Omega} =0\), where \(\Omega \in \mathbb{R}^N\) is an open and bounded set, \(f\), \(g\) are continuous real functions on ...

Locating the QCD Critical Point Using Holographic Black Holes

open access: yesProceedings, 2019
It has been shown that holographic black holes, constructed to mimic the equation of state of QCD computed on the lattice at finite temperature and zero density, display critical behavior at large baryonic chemical potential.

Existence and nonexistence of solutions for elliptic problems with multiple critical exponents

open access: yesOpen Mathematics, 2023
In this article, the existence and nonexistence of solutions for the quasilinear elliptic equations involving multiple critical terms under Dirichlet boundary conditions on bounded smooth domains Ω⊂RN(N≥3)\Omega \subset {R}^{N}(N\ge 3) are proved by ...
