Targeted Metabolomics Induced by Microplastics
It has been reported that microplastics (MPs)  are present in several organs in different species, including the liver, intestines, kidney, and other organs, where they have the potential to cause detrimental effects such as disrupting endocrine regulation, neurotoxicity, and reproductive toxicity. Therefore, metabolomics studies have attracted considerable attention from researchers who are eager to reveal the mechanism behind the biomarkers that have been discovered by serum chemistry tests, histological tests, or polymerase chain reaction (PCR) analyses. Metabolomics studies can be achieved in two ways, namely targeted and untargeted. Targeted metabolomics detects defined groups of metabolites, providing quantitative results with a high degree of sensitivity and data quality. The advantage of targeted metabolomics is that a complicated data process is not required, but that relatively limited information can be obtained in a single analysis.

Orally Fast Disintegrating Tablets for Infants and Children
A significant number of current drug formulations are not suitable for children of different age groups because of heterogeneity of the pediatric population, immature Absorption, Distribution, Metabolism and Elimination (ADME) processes, rapid developmental changes, palatability issues, low drug adherence and ethical concerns. Improvements in flexibility of dose administration, tablet size, taste masking, bioavailability, excipient safety and acceptability, stability, manufacturing and affordability represent multiple opportunities at various scales of child-friendly formulations design to overcome clinical and technological challenges in pediatric drug development. Orally Dispersible Tablets (ODTs) are a promising child-friendly drug delivery strategy, offering a potential solution to address unique medical needs in infants and children while maintaining a favorable excipient safety and acceptability profile in these vulnerable patient populations.

Situation and Sorting of Textiles
The recovery and recycling of textile waste is becoming urgent since textiles are generating more and more waste. In one year, about 92 million tons of textile waste are produced and the fashion industry accounts for 58 million tons of plastic waste per year. Several different synthetic fibres are used in textiles, thanks to their excellent processability and mechanical properties, but on the other hand, the difficulties linked to their end of life and the release of microplastics from them during washing is currently a cause of great concern.

Nanotechnological Approaches for Solubility Enhancement
Nanotechnology has the potential to revitalize both poorly performing marketed drugs and many of those pre-clinically promising candidates that were “beached” due to inadequate water solubility, in addition to novel therapeutic developments using components in the 1–100 nanometer range. As a result of developments in nanotechnology, researchers have been tackling this problem by formulating drugs with the aid of nanocarriers.

Chemical and Physical Properties of Solid Salt Fluxes
Solid salt fluxes are inorganic compounds that are added during the treatment of molten aluminum to improve the final quality. An understanding of the chemical composition of the flux is essential for the assessment of the physical and chemical behavior of the flux. The chemical composition of the flux can be tailored to adjust properties such as density, viscosity, reactivity, and wettability. Such properties, in turn, will impart different functions to the flux.

Silver Nanoparticles for Waste Water Management
Rapidly increasing industrialisation has human needs, but the consequences have added to the environmental harm. The pollution caused by several industries, including the dye industries, generates a large volume of wastewater containing dyes and hazardous chemicals that drains industrial effluents. The growing demand for readily available water, as well as the problem of polluted organic waste in reservoirs and streams, is a critical challenge for proper and sustainable development. Remediation has resulted in the need for an appropriate alternative to clear up the implications. Nanotechnology is an efficient and effective path to improve wastewater treatment/remediation. The effective surface properties and chemical activity of nanoparticles give them a better chance to remove or degrade the dye material from wastewater treatment. AgNPs (silver nanoparticles) are an efficient nanoparticle for the treatment of dye effluent that have been explored in many studies. The antimicrobial activity of AgNPs against several pathogens is well-recognised in the health and agriculture sectors.

New Fenton Catalysts
It is needed found Fenton catalysts with higher reaction rates with catalitic activity similar to the conventional catalysts. The spinel ferrites have attracted increasing interest due to their low cost, excellent catalytic activity, and magnetic properties that allow a facile separation and reutilization, in addition the presence of two differents metals in an same structure can result in a better catalitic activity. Undwer the same idea the perovskites also result interesting for its use as Fenton catalysts due to the sinergic effect betwen the metals of its structure.

Benefits of Chemical Desalination
The ideal chemical desalination approach is undertaken (i) without specialist training, (ii) on a typical agricultural holding (1 to 100 ha−1), and (iii) using existing water tanks and/or impoundments. It reduces the overall feed water required to produce x m3 of water (relative to reverse osmosis). It produces minimal or no waste products that require disposal.

Sol-Gel Technology
The commercial availability of inorganic/organic precursors for sol-gel formulations is very high and increases day by day. In textile applications, the precursor-synthesized sol-gels along with functional chemicals can be deposited onto textile fabrics in one step by rolling, padding, dip-coating, spraying or spin coating. By using this technology, it is possible to provide fabrics with functional/multi-functional characteristics including flame retardant, anti-mosquito, water- repellent, oil-repellent, anti-bacterial, anti-wrinkle, ultraviolet (UV) protection and self-cleaning properties. These surface properties are discussed, describing the history, basic chemistry, factors affecting the sol-gel synthesis, progress in sol-gel technology along with various parameters controlling sol-gel technology. Additionally, this review deals with the recent progress of sol-gel technology in textiles in addressing fabric finishing, water repellent textiles, oil/water separation, flame retardant, UV protection and self-cleaning, self-sterilizing, wrinkle resistance, heat storage, photochromic and thermochromic color changes and the improvement of the durability and wear resistance properties.

Metal Oxide Semiconductor Gas Sensors with Different Morphologies
There is an increasing need for the development of low-cost and highly sensitive gas sensors for environmental, commercial, and industrial applications in various areas, such as hazardous gas monitoring, safety, and emission control in combustion processes. Considering this, resistive-based gas sensors using metal oxide semiconductors (MOSs) have gained special attention owing to their high sensing performance, high stability, and low cost of synthesis and fabrication. The relatively low final costs of these gas sensors allow their commercialization; consequently, they are widely used and available at low prices. Different morphologies of metal oxide gas sensors are discussed.
