Compounds of Lead
Compounds of lead exist in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions.

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.

Biography
John Fenn
John Bennett Fenn (June 15, 1917 – December 10, 2010) was an American professor of analytical chemistry who was awarded a share of the Nobel Prize in Chemistry in 2002. Fenn shared half of the award with Koichi Tanaka for their work in mass spectrometry. The other half of the 2002 award went to Kurt Wüthrich. Fenn's contributions specifically related to the development of electrospray ioniza

Hot Electrons in Plasmon-Sensitized TiO2
Hot carriers are electron-hole pairs formed by Landau damping or chemical interface damping of particle plasmons. The term “hot electrons” not only describes the individual electrons themselves, but also describes the Fermi–Dirac distribution of electrons in a solid albeit with an elevated effective temperature—the effective temperatures involved when considering the carrier kinetic energies and carrier densities in the solid, and not that of the solid itself- as opposed to thermal equilibrium. Typically, hot carriers lose their excess energy and relax to thermal equilibrium within a few picoseconds of formation due to a variety of scattering processes. Therefore, it is very difficult to extract useful work from hot carriers with thermodynamic efficiencies that are of interest for practical devices. However, heterojunctions of TiO2 with coinage metals have been consistently shown to be effective in utilizing hot carriers to perform useful work, such as driving a chemical reaction or generating an electric current. A secondary benefit of such TiO2-coinage metal heterojunctions is the "visible light sensitization" effect which allows broader harvesting of visible light.

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.

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.

Applications of Polyvinyl Alcohol-Chitosan Hydrogel
Tissue engineering and regenerative medicine (TERM) holds great promise for addressing the growing need for innovative therapies to treat disease conditions. To achieve this, TERM relies on various strategies and techniques. The most prominent strategy is the development of a scaffold. Polyvinyl alcohol-chitosan (PVA-CS) scaffold emerged as a promising material in this field due to its biocompatibility, versatility, and ability to support cell growth and tissue regeneration.
