Ternary III−As Antimonide
During the last few years, there has been renewed interest in the monolithic integration of gold-free, Ternary III–As Antimonide (III–As–Sb) compound semiconductor materials on complementary metal-oxide-semiconductor (CMOS)—compatible silicon substrate to exploit its scalability, and relative abundance in high-performance and cost-effective integrated circuits based on the well-established technology. Ternary III–As–Sb nanowires (NWs) hold enormous promise for the fabrication of high-performance optoelectronic nanodevices with tunable bandgap. However, the direct epitaxial growth of gold-free ternary III–As–Sb NWs on silicon is extremely challenging, due to the surfactant effect of Sb.

Ternary Al–Ni–Er System
Al–Ni–Er is an essential system in heat-resistant Al alloys. The aluminum-rich corner of this system, which has the most practical application significance. The phase equilibria of the Al–Ni–Er system are investigated via experiments and thermodynamic modeling. The isothermal sections of the Al-rich corner of this ternary system at 600 and 700 °C were determined through equilibrated alloys combined with scanning electron microscopy (SEM), electron probe microanalysis (EPMA) and X-ray diffractometry (XRD).

Templated Twist Structure Liquid Crystals and Photonic Applications
Twist structure liquid crystals (TSLCs) have attracted increasing attention in photonic applications due to their distinct properties: Bragg reflection, scattering, and optical rotation. However, there exist some issues due to the defects of TSLCs: weak thermal stability, narrow bandwidth, and complicated fabrication. The templating technique which includes device structure, templating process, and photonic properties of templated TSLCs to improve the issues was introduced. Furthermore, a variety of photonic applications including lasing, optical filters and gratings based on TSLCs with polymer templates are presented. Additionally, other applications of TSLCs are briefly introduced. Finally, the remaining challenges and future perspectives of templated TSLCs are proposed.

Temperature Sensors for Thermoregulation in Personal Protective Equipment
The exposure to extreme temperatures in workplaces involves physical hazards for workers. A poorly acclimated worker may have lower performance and vigilance and therefore may be more exposed to accidents and injuries. Due to the incompatibility of the existing standards implemented in some workplaces and the lack of thermoregulation in many types of protective equipment, thermal stress remains one of the most frequent physical hazards in many work sectors. In order to provide a better protection of individuals against thermal aggressors, the scientific community has been interested in the development of the textile-based or flexible temperature sensors that can be integrated into personal protective equipment. These sensors can measure the skin temperature and monitor the microclimate temperature between the body and the clothing or the outside temperature during exposure to thermal aggressors.

Tellurium Nanotubes and Chemical Analogues
Tellurium (Te), the most metallic semiconductor, has been widely explored in recent decades owing to its fantastic properties such as a tunable bandgap, high carrier mobility, high thermal conductivity, and in-plane anisotropy. Many references have witnessed the rapid development of synthesizing diverse Te geometries with controllable shapes, sizes, and structures in different strategies. In all types of Te nanostructures, Te with one-dimensional (1D) hollow internal structures, especially nanotubes (NTs), have attracted extensive attention and been utilized in various fields of applications.

Technologies for Detecting Oxygen Vacancies
A perovskite catalyst combined with various advanced oxidation processes (AOPs) to treat organic wastewater attracted extensive attention. The physical and chemical catalytic properties of perovskite were largely related to oxygen vacancies (OVs). OVs were able to alter the chemical, physical, and electronic properties of materials, so they became one of the most important research subjects. It was usually necessary to observe and analyze the phenomenon caused by OVs; however, due to their low concentration and short existence time, OVs were normally not visible to the naked eye. The relative concentration of OVs ranged from PPM to tens of atomic percent, a condition that was difficult to find a fitting experimental plan to characterize and distinguish OVs.

Technological Uses of Thioketal in Drug Delivery Systems
To take advantage of ROS-specific cleavage, different technological uses of Thioketal (TK) functional group have been proposed in the design of selective and improved “smart” nanosystems, including as linker to connect a drug on the surface of nanoparticles, form prodrugs, as a core component of the Drug Delivery System (DDS) to directly control its structure, to control the opening of drug-releasing gates or to change the conformation of the nano-systems. This allows to overcome the major limitations of conventional DDS counterparts, including uncontrolled drug release and off-target effects, by controlling the degradation kinetics, drug release kinetics, or even increasing potential administration routes.

Techniques for the Analysis of Trace Tin Concentrations
Tin determination allows for the monitoring of pollution and assessment of the impact of human activities on the environment. The determination of tin in the environment is crucial for the protection of human health and ecosystems, and for maintaining sustainability. Tin can be released into the environment from various sources, such as industry, transportation, and electronic waste. The concentration of tin in the environment can be determined by different analytical methods, depending on the form of tin present and the purpose of the analysis. The choice of an appropriate method depends on the type of sample, concentration levels, and the available instrumentation.
