Article Abstract
Designing new materials for vibration and noise reduction that are lightweight is of great significance for industrial development. Magnesium (Mg) alloy is considered one of the best damping metal structural materials because of its low density, high specific strength, good energy storage characteristics and rich resources. Solution atoms have an important effect on the damping capacities of Mg alloys, but the relevant laws have not been completely clarified. In this work, two kinds of alloying elements (Ga and Er) with various atomic sizes were selected to study the metallographic structure and damping capacities of binary Mg-X (X = Ga and Er) alloys in the as-cast and solid solution states, respectively. Solution treatment can improve the damping capacities of binary Mg-X (X = Ga and Er) alloys, and the damping mechanisms of the two solid solution alloys are consistent with the G-L damping mechanism. The influence of alloy elements with different atomic sizes on damping capacities is also different. This influence is due to the various radii of solute atoms and Mg atoms which can result in different degrees of lattice distortion. This work provides a research basis for development and design of high-performance damping Mg alloy materials.

School of Aeronautics, Northwestern Polytechnical University, Xi'an 710072, China.
In this paper, we prepared carbon nanotube (CNT) epoxy composite films and conducted tensile experiments at various temperatures (-40 °C, -10 °C, 20 °C, and 50 °C) and frequencies (1 Hz, 10 Hz, and 20 Hz) using Dynamic Mechanical Analysis (DMA). This study reveals the effects of temperature and frequency on the mechanical properties of CNT films and CNT epoxy composite films. The results indicate that the energy storage modulus of the pure CNT film is approximately 13 times greater than that of the composite material at 20 °C.

The present study investigates the effect of ultrasonication (US) amplitude (30 %, 50 %, and 70 %, time- 45 min) followed by octenyl succinic anhydride (OSA, 3 %) esterification on morphological, structural, functional, and rheological properties of sorghum starch. The increase in US amplitudes significantly (p < 0.05) increased the degree of substitution (DS) of esterified starch (0.

Article Synopsis
- Flexible and wearable devices are proving useful for human-machine interactions (HMIs) and the Internet of Things, but there's a need for better communication storage and simpler designs.
- A new approach inspired by natural tendons uses magnetized strings to detect vibrations; the strings' unique frequencies send signals through a single channel, allowing for multiple commands.
- This method allows for customizable interactions by adjusting string tension, demonstrating potential use in areas like authentication, robotics, and other multifunctional applications.
The Effect of Protective Mat Thickness on the Upper Limb Strike Force Simulation in Combat Sports and Self Defense.

The strike force in combat sports strongly depends on the protective material's mechanical properties and energy absorption capacity. Therefore, this study aimed to estimate the effect of the protective layer thickness and repeated loading on the net force in a falling weight impact test. A falling 8-kg weight dropped from 15 cm, 25 cm, and 50 cm was used to simulate impact peak forces in an upper limb strike.

The effects of severe plastic deformation on NiTi alloys' structure and properties have been extensively studied over the past decades. However, there is a notable lack of systematic data regarding the impact of industrial hot deformation techniques on these alloys. This gap arises from challenges in manufacturing processes related to the unevenness of ingots produced by casting technologies.
