Summary: In this study, n-Type ZnO nanorods were successfully grown on a p-type Si substrate using the hydrothermal technique, and ZnO-based UV photodiodes were fabricated. The structural properties of the ZnO nanorod arrays were found to be influenced by the solution volume in the hydrothermal process, with well-aligned arrays observed on all substrates. Increasing the growth solution volume resulted in higher responsivity of the ZnO-based photodiodes, and the optical properties of the samples were also affected by this volume change.

Summary: In this study, suspended micro-mechanical structures were successfully fabricated from nanometer-thick ETO films, and their mechanical properties were characterized. Temperature-dependent measurements revealed a non-monotonic and hysteretic mechanical response in the ETO films. Additionally, the influence of oxygen vacancies on the mechanical properties was investigated by comparing stoichiometric and oxygen-deficient samples.

Summary: Zinc oxide arrays with various microscopic morphologies are grown on fluorine-doped tin oxide substrates using a hydrothermal method, with the relationship between microscopic morphologies and reaction conditions studied in depth. The concentration of free Zn2+ ions in the solution is found to be the key factor affecting microstructures. The competition between kinetic control and thermodynamic control during crystal growth is determined by the concentration of the free Zn2+ ions, leading to the formation of different microscopic morphologies.

Summary: The morphological properties of ZnO nanostructures such as nanorods, nanowires, and nanotubes can significantly affect their photocatalytic performance. In this study, the physical properties (optical and shape) of different 1-D ZnO nanostructures were evaluated in relation to their photocatalytic efficiency. ZnO nanorods transformed into nanowires under reduced seeding precursor concentration and into nanotubes with prolonged incubation time. The highest photocatalytic efficiency was observed in ZnO nanotubes, followed by ZnO nanowires and nanorods. The enhanced efficiency of ZnO nanotubes was attributed to their large polar face, high UV absorption, and large photocurrent density.

Summary: A strategy called elasto-plastic design of an ultrathin interlayer is proposed to enhance the strain tolerance of flexible electronics. By inserting an ultrathin, stiff, and elastic interlayer between a rigid film/device and a soft substrate, the actual strain applied on the film/device can be significantly reduced when the substrate is bent.

Summary: Elemental doping of In in ZnO thin films showed improved performance with higher photocurrent density and enhanced light absorption, leading to smaller charge transfer resistance. This indicates that In-doped ZnO could be a potential photoelectrode for light-harvesting and water splitting applications.

Summary: In this study, it was found that the addition of chitosan can decrease the mechanical stability of soils and generally increase soil porosity. However, for acidic soils, the mechanical stability increased and porosity decreased with the appropriate addition of chitosan. Furthermore, chitosan also affected the wettability and stability of the soils.

Summary: The longitudinal elastic modulus of glasses (GeS4)x(AsS3)1-x was determined based on experimentally measured density and ultrasound velocity relative to the first sharp diffraction peak (FSDP) of XRD halos. The study found a strong correlation between middle range ordering parameters and elastic modulus, indicating the significant impact of middle range ordered domains on the physical properties of the glass.

Summary: The usage and demand of wood plastic composite (WPC) have increased due to its unique chemical and mechanical properties compared to other plastic materials. However, exposure to the external environment can cause structural and mechanical changes to the material. More research is needed, especially when the fiber content is low. In this study, composite materials composed of high-density polyethylene (HDPE) reinforced with yellow birch fibers were made and treated with dissolved zinc oxide (ZnO) powder in sodium oxide (NaOH) solution. The material was exposed to fungal rot, and the mechanical properties were assessed. The results showed that ZnO treatment prevented fungal growth but resulted in decreased mechanical properties.

Summary: Twist-spun carbon nanotube (CNT) yarns consist of numerous CNTs and their bundles which have entangled and twisted structures. While individual CNTs have high mechanical strength, CNT yarns are flexible and can change shape, making them suitable for wearable device design. By adjusting the geometrical structure, a wide range of Young's modulus can be achieved, allowing for various applications requiring different stresses.

Summary: In this critical review, we address the issue of the vast disagreement in reported elastic moduli values for nanostructures made of the same material. As a case study, we focus on ZnO nanowires, which have been extensively studied due to their remarkable physical properties and potential applications. Despite considering the same growth direction and crystal structure, there is a significant variation in reported Young's modulus values, ranging from 20 to 800 GPa. This work provides a critical overview and thorough analysis of existing experimental and theoretical studies in order to identify the most significant sources of errors and reliable results.

Summary: The physical and chemical properties of quaternary copper-barium-thiostannate (Cu2BaSnS4) compound were investigated in this study. Cu2BaSnS4 (CBTS) thin films were synthesized using a cost-effective sol-gel spin-coating technique, revealing a significant enhancement in photocurrent density under AM 1.5G condition. The p-type nature of CBTS was confirmed, and its suitability for harvesting solar energy was demonstrated through the fabrication of Pt free photoelectrochemical cells with ZnO nanorods as counter electrodes.
