Numerical Modeling of the Thermo‐Mechanical and Electrical Behavior of a Sensor‐Integrating Jaw Coupling

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Industry 4.0 requires more and more data from the production process, for example, on transmitted forces, torques and wear, in order to reduce expensive downtimes and to increase productivity. Direct or indirect methods can be used to collect this data.

Energy Decay of Solutions for a System of Higher-Order Kirchhoff Type Equations

open access: yesJournal of New Theory, 2019
In this work, we considered asystem of higher-order Kirchhoff type equations with initial and boundaryconditions in a bounded domain. Under suitable conditions, we proved an energydecay result by Nakao's inequality techniques.

Electrochemical Memristive Devices Toward Brain‐Inspired Computing and In‐Memory Communication: Mechanisms, Materials, and Device Engineering

open access: yesChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Electrochemical memristive devices, whose resistance is modulated by ion migration and redox reactions, offer a hardware pathway toward brain‐inspired computing. This review summarizes key switching mechanisms—electrochemical metallization (ECM), valence change mechanism (VCM), and thermochemical effects (TCM)—and discusses how materials and device ...

Deformation‐Induced Formation of Stray Grains in Additive Manufacturing of Single Crystals

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
Stray grain formation severely limits the additive manufacturing of single‐crystal alloys. By integrating in situ synchrotron techniques, ex situ characterization, and multi‐scale multi‐physics modeling, the authors reveal that stray grains originate from dislocations at the solid‐liquid interface, rather than thermal supercooling in conventional ...

Ground state solution of a nonlocal boundary-value problem

open access: yes, 2013
In this paper, we apply the method of the Nehari manifold to study the Kirchhoff type equation \begin{equation*} -\Big(a+b\int_\Omega|\nabla u|^2dx\Big)\Delta u=f(x,u) \end{equation*} submitted to Dirichlet boundary conditions.

Large‐Aperture Polarization‐Independent Broadband Achromatic All‐Dielectric Metalens for Terahertz Focusing

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
A large‐aperture, high focusing efficiency and polarization‐independent THz single‐layer achromatic metalens is reported via discrete multi‐wavelength achromatic design and global optimization algorithm. The fabricated metalens exhibits a largest diameter of 2.21 cm, excellent achromatic performance, extremely high average focusing efficiency (> 46 ...

Random attractors of Kirchhoff-type reaction–diffusion equations without uniqueness driven by nonlinear colored noise

open access: yesOpen Mathematics
In this article, we consider the asymptotic behavior of solutions for the Kirchhoff-type reaction–diffusion equations driven by a nonlinear colored noise defined on unbounded domains. We prove the existence and uniqueness of pullback random attractors by

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Bio‐Inspired Ordered WO3 Nano‐Helixes Enable Multi‐Band Electrochromic Smart Windows with Ultrafast Switching and Robust Cyclability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
Biomimetic ordered nano‐helix WO3 films enable multi‐band electrochromic photothermal management across the visible, near‐infrared, mid‐ and long‐wave infrared spectra, with ultrafast switching (<3 s) and robust durability (>10 000 cycles). These findings establish new paradigms for next‐generation photothermal management systems and energy‐efficient ...
