Methods for Reducing Water Absorption of Composite Materials
Plant fiber reinforced polymer matrix composites have attracted much attention in many industries due to their abundant resources, low cost, biodegradability, and lightweight properties. Compared with synthetic fibers, various plant fibers are easy to obtain and have different characteristics, making them a substitute for synthetic fiber composite materials. In order to address the adverse effects of natural fiber moisture absorption on the mechanical properties and dimensional stability of composite materials, researchers have modified fibers through various chemical and physical methods. The various methods to reduce the water absorption of composite materials such as fiber surface chemical treatment, the use of compatibilizers, fiber mixing, nanofillers, and polymer coatings.

Electrospun Polysaccharidic Textiles for Biomedicine
Recent developments in electrospinning technology have enabled the commercial-scale production of nonwoven fabrics from synthetic and natural polymers. Since the early 2000s, polysaccharides and their derivatives have been recognized as promising raw materials for electrospinning, and their electrospun textiles have attracted increasing attention for their diverse potential applications. In particular, their biomedical applications have been spotlighted thanks to their “green” aspects, e.g., abundance in nature, biocompatibility, and biodegradability. This review focuses on three main research topics in the biomedical applications of electrospun polysaccharidic textiles: (i) delivery of therapeutic molecules, (ii) tissue engineering, and (iii) wound healing, and discusses recent progress and prospects.

Effervescence-Assisted Microextraction
Effervescence-assisted microextraction emerged in 2011 as a new alternative in this context. The technique uses in situ-generated carbon dioxide as the disperser, and it has been successfully applied in the solid-phase and liquid-phase microextraction fields. This minireview explains the main fundamentals of the technique, its potential and the main developments reported.

Genus Mentha
Mint (Mentha species) exhibits multiple health beneficial properties, such as prevention from cancer development and anti-obesity, antimicrobial, anti-inflammatory, anti-diabetic, and cardioprotective effects, as a result of its antioxidant potential, combined with low toxicity and high efficacy. Mentha species are widely used in savory dishes, food, beverages, and confectionary products. Phytochemicals derived from mint also showed anticancer activity against different types of human cancers such as cervix, lung, breast and many others. Mint essential oils show a great cytotoxicity potential, by modulating MAPK and PI3k/Akt pathways; they also induce apoptosis, suppress invasion and migration potential of cancer cells lines along with cell cycle arrest, upregulation of Bax and p53 genes, modulation of TNF, IL-6, IFN-γ, IL-8, and induction of senescence phenotype. Essential oils from mint have also been found to exert antibacterial activities against Bacillus subtilis, Streptococcus aureus, Pseudomonas aeruginosa, and many others.

Quantum Dots for Optoelectronic Applications
Quantum dots (QDs) are tiny semiconductor particles that typically range in size from 2 to 10 nanometers. Because of their small size, they have unique optical and electrical properties, resulting in quantum confinement of electrons and holes within the material. This confinement results in discrete energy levels, and the energy of the confined particles is determined by the size of the QDs QDs could be used in a variety of applications, including displays, solar cells, medical imaging, and quantum computing.. They are typically only a few nanometers in size. QDs can be employed as a light-sensitive substance, also referred to as a photoconductive substance, in a photodetector.

Human Osteosarcoma
Osteosarcoma (OSA) (also called osteogenic sarcoma) is the most common type of cancer that starts in the bones. It is the most frequent pediatric primary bone tumor. OSA is a rare mesenchymal bone neoplasm derived from mesenchymal stem cells. Genome disorganization, chromosomal modifications, deregulation of tumor suppressor genes, and DNA repair defects are the factors most responsible for OSA development. Recent Progress in nanotechnology platforms in human OSA inspire new ideas to develop more effective therapeutic options.

Nanostructured Lipid Carriers-Hydrogels System for Drug Delivery
Nanostructured lipid carriers (NLC) are lipid nanoparticles of the second generation made up of solid lipid matrices mixed with liquid lipids (oils). The hybrid system between NLC and hydrogel may results in the enhancement of each component's synergistic properties in the mechanical strength of the hydrogel and concomitantly decrease aggregation of the NLC. Therefore, the advanced hybrid component development in nanotechnology provides superior functionality in the application of scientific knowledge for the drug delivery industry.

Glass Fiber Coated Sol–Gel Poly-Diphenylsiloxane
A novel simple and sensitive, time-based flow injection solid phase extraction system was developed for the automated determination of metals at low concentration. The potential of the proposed scheme, coupled with flame atomic absorption spectrometry (FAAS), was demonstrated for trace lead and chromium(VI) determination in environmental water samples. The new sorptive extraction system, consisted of an online microcolumn packed with glass fiber coated with sol–gel poly (diphenylsiloxane) (sol–gel PDPS), which is presented here for the first time.
