2D Nanofluids
The homogeneous dispersions of 2D nanomaterials in heat transfer base fluids—so-called 2D nanofluids. The data compilation emerged from the critical overview of the findings of the published scientific articles regarding 2D nanofluids. The applicability of such fluids as promising alternatives to the conventional heat transfer and thermal energy storage fluids is comprehensively investigated. These are fluids that simultaneously possess superior thermophysical properties and can be processed according to innovative environmentally friendly methods and techniques.

3D Printed Nonlinear Musculoskeletal Actuator
A nature-inspired musculoskeletal-actuator system is developed using 3d printing for robotic applications. The actuator resembles the rigid segments and the soft-rigid interaction architecture found in limbless vertebrates such as snakes. The rigid segments provide an increase in the range of motion while maintaining structural durability and stability. The soft-rigid interactions provided a remarkable increase in energy transmission and storage, which enhanced the reliability of the musculoskeletal-actuator. Additionally, passive structural stiffness and damping control are achieved. Similar to a muscular system, our musculoskeletal-actuator is capable of increasing its stiffness and damping up to 100% and 60%, respectively, upon load lifting.

3D Printing to Produce BioComposite
Current environmental concerns have led to a search of more environmentally friendly manufacturing methods, thus, natural fibers have gained attention in the 3D printing industry to be used as biofilters along with thermoplastics. The utilization of natural fibers is very convenient as they are easily available, cost-effective, eco-friendly, and biodegradable. Using natural fibers rather than synthetic fibers in the production of the 3D printing filaments will reduces gas emissions associated with the production of the synthetic fibers that would add to the current pollution problem. As a matter of fact, natural fibers have a reinforcing effect on plastics. This review analyzes how the properties of the different types of polymers vary when natural fibers processed to produce filaments for 3D Printing are added. The results of using natural fibers for 3D Printing are presented in this study and appeared to be satisfactory, while a limited number of studies have reported some issues.

A Novel Composited Electromagnetic Linear Actuator
Electromagnetic linear actuators, as key executive components, have a vital impact on the performance of fully flexible variable valve trains. The research results show that the maximum starting force of the composited electromagnetic linear actuator (CELA) with the end-passive self-holding ability is 574.92 N while the holding force can approach 229.25 N. Moreover, the CELA is proven to have excellent dynamic characteristics and control precision under different motion modes and to have an improved adaptability to the complex working conditions of internal combustion engines.

A Unified Treatment of Tribo-Components Degradation
According to the degradation-entropy generation (DEG) theorem, material degradation is irreversible and always accompanied by entropy generation. When applied to the degradation of a tribo-component, the DEG theorem relates the rate of change in wear volume to thermodynamic force via a parameter known as the degradation coefficient B. The efficacy of the B over the well-established Archard coefficient has been experimentally demonstrated for tribo-components that experience wear under running-in and steady-state operating conditions. The steady wear includes uni-directional, bi-directional, uniform, and variable operating conditions.

A Vision-Based Micro-Manipulation System
Micro-manipulation systems play a critical role in various scientific and industrial applications, enabling precise handling and control of microscopic objects. Precise micro-manipulation is essential, whether it involves the assembly of microelectronic components, the handling of biological samples, or the fabrication of micro-scale structures. However, achieving accurate manipulation at the micro-scale poses unique challenges, primarily due to the minuscule size of the objects involved.

AA 6061 Metal Matrix Composites
AA 6061 is an aluminium alloy that has extensive applications due to its superior material characteristics. It is a popular choice of matrix for aluminium matrix composite (AMC) fabrication. Stir casting method is widely for fabricating AA 6061 composites with reinforcements such as SiC, B4C, Al2O3, TiC, other inorganic, organic, hybrid and nanomaterials. An increase in reinforcement content enhances the mechanical and tribological properties of the composites. Hybrid composites show better material properties than single reinforcement composites.
