A Look at Generalized Trigonometric Functions as Functions of Their Two Parameters and Further New Properties

Mathematics
Investigation of the generalized trigonometric and hyperbolic functions containing two parameters has been a very active research area over the last decade.

Fast and Furious: A study on Monotonicity and Speed in Cops-and-Robber Games [PDF]

arXiv
In this paper, we study different variants of the Cops-and-Robber game with respect to cop- and robber\-/monotonicity. We study a visible and invisible robber and variants where the robber is lazy, thus can only move when the cops announce to move on top of him.

Supramolecular Nanoarchitectonics of PNIPAAM‐co‐MA and Imogolite to Obtain Thermoresponsive Clay Nanotubes Through Complexation Mechanism

Advanced Materials Interfaces, EarlyView.
The selective adsorption of anionic poly(N‐isopropylacrylamide)‐co‐methacrylic (PNIPAAM‐co‐MA) onto the external surface of imogolite nanotubes is driven by electrostatic attractions. The copolymer coating affects the surface charge, aqueous diffusion and self‐assembling of imogolite.

Unraveling the Effects of Improved Cooling and Bias Force in the Actuation of a Shape‐Memory Soft Multimaterial Gripper

Advanced Materials Technologies, EarlyView.
This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.

Dynamic Excitonic Beam Switching with Atomically‐Thin Binary Blazed Gratings

Advanced Optical Materials, EarlyView.
Two mirrored and interleaved blazed gratings are patterned into a monolayer WS2, contacted with gold electrodes inside an electrochemical cell. Applying a gate voltage to one of the grating electrode suppresses the exciton in that grating, enabling selective beam switching between diffractive orders.

Enhancing Amplified Spontaneous Emission in Perovskite Thin Films by Thickness Regulation: Insights into Carrier Distribution and Optical Confinement

Advanced Optical Materials, EarlyView.
This study reveals the critical influence of film thickness and excitation wavelength on the ASE threshold in metal halide perovskites. By optimizing these factors, the ASE threshold is significantly reduced, providing key insights into optical confinement and carrier distribution for advancing electrically pumped perovskite lasers.
