Advanced Engineering Materials, EarlyView.Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Advanced Engineering Materials, EarlyView.Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

A Modulus of Continuity for a Class of Quasi-Smooth Functions [PDF]
Proceedings of the American Mathematical Society, 1985 Let Z be the Zygmund class of functions f on [-1,1] such that \(f(- 1)=f(1)=0\) and \(| \Delta^ 2_ hf| \leq 2h.\) Let \(\omega (h)=\sup_{f\in Z}\sup_{| x-y| \leq h}| f(x)-f(y)|.\) Theorem. \[ \omega (h)\leq h \log_ 2\{2eK/(h \log_ 2 e)\}; \] here \(K=\sup_{f\in Z}\sup_{x}| f(x)\).

Advanced Engineering Materials, EarlyView.This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

On the local H\"older boundary smoothness of an analytic function in the unit ball compared with the smoothness of its modulus [PDF]
, 2019 Local boundary smoothness of an analytic function f on the unit ball of C^n is compared to the smoothness of its modulus. We prove that different conditions imposed on the zeros of f imply different drops of the smoothness.

Design of a Multistable Finger Prosthesis with Programmable Metamaterials
Advanced Engineering Materials, EarlyView.This research article shows the development of a multistable programmble metamaterial for the use as a finger prosthesis. The material was designed on different hierarchical levels where the influence of geometrical parameters and combination of mechanical elements was explored.

A computational analysis of a family of Szász type operators based on Tricomi functions
Journal of Inequalities and ApplicationsThis paper introduces a novel family of integral operators incorporating Tricomi functions. We derive explicit estimates for test functions and central moments, alongside establishing uniform convergence via the Korovkin theorem and approximation order ...
