Pt(η3–P1C2X1C2P2)(Y) Derivative Types
Structural data are classified and analyzed for almost seventy complexes of the general formula Pt(η3–P1X1P2)(Y) (X1 = O, N, C, S, Si) and (Y = various monodentate ligands), in which the respective η3–P1X1P2 ligand forms a pair of five-membered metallocyclic rings with a common X1 atom of the P1C2X1C2P2 type.

Lignin-Based Hydrogels for Biomedical Applications
Different techniques have been developed to overcome the recalcitrant nature of lignocellulosic biomass and extract lignin biopolymer. Lignin has gained considerable interest owing to its attractive properties. These properties may be more beneficial when including lignin in the preparation of highly desired value-added products, including hydrogels. Lignin biopolymer, as one of the three major components of lignocellulosic biomaterials, has attracted significant interest in the biomedical field due to its biocompatibility, biodegradability, and antioxidant and antimicrobial activities.

Types of Soil Contaminants and Their Harmful Effects
Soil can be understood as a 3D structure that is interconnected with components of the environment, such as air and water. Therefore, if the soil is contaminated, the contamination can easily spread, leading to great risks to human life, ecosystems, water sources, and other environmental receptors. Additionally, the pollutants can be transmitted to the bodies of people who eat crops produced from the soil. The constant contact between dirt that is polluted and the air and water can be hazardous to the environment and human health. Trace elements can lead to digestive problems such as intense pains, diarrhea, vomiting, ulcers, skin problems, lung cancer, changes in genetic material, and other human illnesses.

Phytocannabinoids, Endocannabinoids and Synthetic Cannabinoids
Generally, the term ‘cannabinoids’ refers to a heterogeneous family of compounds that exhibit activity upon particular human cannabinoid receptors, namely CB1 and CB2. They encompass the natural compounds present in the Cannabis plants, lipid mediators called ECs naturally produced by human cells, as well as by all vertebrates on planet Earth, and the synthetic analogs of both groups designed by scientist, called SCs.

Fluorinated Drugs Approved by the FDA (2016–2022)
Fluorine is characterized by high electronegativity and small atomic size, which provide this molecule with the unique property of augmenting the potency, selectivity, metabolic stability, and pharmacokinetics of drugs. Fluorine (F) substitution has been extensively explored in drug research as a means of improving biological activity and enhancing chemical or metabolic stability. Selective F substitution onto a therapeutic or diagnostic drug candidate can enhance several pharmacokinetic and physicochemical properties such as metabolic stability and membrane permeation. The increased binding ability of fluorinated drug target proteins has also been reported in some cases. An emerging line of research on F substitution has been addressed by using 18F as a radiolabel tracer atom in the extremely sensitive methodology of positron emission tomography (PET) imaging.

Applications of Two-Dimensional Transition Metal Dichalcogenides
Two-dimensional (2D) transition metal dichalcogenides (TMDCs) nanosheets have shown extensive applications due to their excellent physical and chemical properties. However, the low light absorption efficiency limits their application in optoelectronics. By rolling up 2D TMDCs nanosheets, the one-dimensional (1D) TMDCs nanoscrolls are formed with spiral tubular structure, tunable interlayer spacing, and opening ends. Due to the increased thickness of the scroll structure, the light absorption is enhanced. Meanwhile, the rapid electron transportation is confined along the 1D structure.
