Summary: This paper develops a novel continuum mechanics model to investigate the influence of surface effects on the bending and free vibration behaviors of Kirchhoff rectangular nano laminates. The results show that the influences of surface effects on bending deflections and natural frequencies are related to the aspect ratio of the nano laminates and the value of residual surface stress. Moreover, the influence of surface effects can be ignored when the thickness of the nano laminate is large enough.

Summary: Elliptical vibration cutting (EVC) is a promising technique for fabricating microstructures on brittle materials. This study investigates the effects of EVC on surface quality and energy consumption in ultra-precision machining. Experimental and theoretical analyses reveal that EVC significantly improves machining quality and reduces energy consumption compared to ordinary cutting. Increasing vibration amplitude in the cutting direction can further save energy, but care must be taken to minimize subsurface damage.

Summary: This paper proposes a new analytical model for elastic vibrations of thin-walled box-like long cylindrical structures commonly seen in railway vehicle carbodies, aircraft, and buses. The model considers the three-dimensional elastic vibrations of the carbody, which is composed of elastic plates and beams connected with artificial springs. By introducing curved elastic beams as pillars in the side structures, the authors simplify the expression of the three-dimensional deformation and name the model the curved box model. The paper investigates the free vibration of the model using the Ritz method and calculates the modal characteristics of elastic vibrations.

Summary: This study utilized a one-step KOH activation method to produce ultra-high mesoporous activated carbons with a surface area of 3207 m2 g-1 and a mesopore ratio of 76%. These activated carbons were used for supercapacitors and methylene blue adsorption, showing promising results in terms of capacitance and adsorption capacity. By adjusting the process conditions, the mesopore ratio of the activated carbons could be controlled. A two-step method was also explored, resulting in different properties but with potential advantages in electrochemical performance. Techno-economic analysis demonstrated the economic viability of the one-step activation-based process.

Summary: The formation and accumulation of ice have negative effects on commercial surfaces and human lives. Increasing surface hydrophobicity decreases ice adhesion strength, and superhydrophobic surfaces can be created by combining low surface free energy and high surface roughness. Inspired by bio-mimetic studies on biological surfaces, artificial bio-inspired superhydrophobic surfaces have been widely designed and constructed, with both superhydrophobic and anti-icing/icephobic properties.

Summary: This study investigates the effects of ultrasonic vibration on the vibration-assisted nanogrinding process of single-crystal iron using a molecular dynamics model. The results show that vibration changes the distribution of dislocations in the plastic zone, leading to fluctuations in material accumulation, temperature, dislocation formation, and subsurface damage. The details of plastic deformation, such as dislocation movement and phase transformation, vary with different vibration frequencies. The reduction in the projected contact area is the main cause for the decrease in grinding force.

Summary: This study presents a novel approach using femtosecond laser technology to fabricate nano cones-like structures of rutile titanium oxides (NCS-TiO2) on the surface of titanium. Molecular dynamic simulation reveals that the growth of rutile titanium oxides and the formation of nano cones-like structures are attributed to the interplay between femtosecond laser ablation and the accumulation of thermal energy. The proposed method offers a versatile and straightforward approach for creating functional surfaces on metal substrates, enabling broad applicability and ease of implementation, specifically in titanium and its alloys.

Summary: This paper discusses the influence of multiple impacts on the compression strength of honeycomb sandwich structures with composite face sheets. It is found that the size of the impactor affects the turning point of the compression strength. Additionally, high impact energy leads to damage in the bottom face sheet and reduces the overall compression strength.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
