Molecularly Imprinted Polymer-Based Luminescent Chemosensors
Molecularly imprinted polymer (MIP)-based luminescent chemosensors combine the advantages of the highly specific molecular recognition of the imprinting sites and the high sensitivity with the luminescence detection. Luminescent molecularly imprinted polymers (luminescent MIPs) towards different targeted analytes are constructed with different strategies, such as the incorporation of luminescent functional monomers, physical entrapment, covalent attachment of luminescent signaling elements on the MIPs, and surface-imprinting polymerization on the luminescent nanomaterials.

Degradation of Rubber and Plastics by Oxidative Metalloenzymes
Biomass wastes are produced daily by different sources, such as residues from forestry, agriculture, and food industry or animal, food, and municipal solid wastes. Bioconversion of this non-edible biomass using microorganisms emerged as a promising green strategy to valorize the non-starch polymers that not only plants but crustaceans as well use to support and protect themselves.

Nuclear Waste Disposal
Nuclear waste (like radioactive waste) is waste that contains, or is contaminated with, radionuclides, at activity concentrations greater than clearance levels set by the regulators, beyond which no further use is foreseen. Disposal is the emplacement of waste in an appropriate facility without the intention to retrieve it.

Au(III) Cyclometallated Compounds with 2-Arylpyridines
A large numbers of reports (>100) described molecules (>500) and single crystal X-ray structures (>200) indicated that the Au(III) compounds with 2-arylpyridines* and their derivatives or analogues are interesting from the chemical, spectroscopic, and structural viewpoints. The most popular Au(III)-2PPY* species are those with 2-phenylpyridine* and 2-(4-methylphenyl)pyridine*, while among Au(III)-2ArPY* molecules-those containing 2-benzylpyridine* ring system.

Mechanochemical Synthesis of Nanoparticles
Various solvent-based approaches have been already used to synthesize porous materials. Mechanochemical synthesis is one of the effective eco-friendly alternatives to the conventional synthesis. It adopts the efficient mixing of reactants using ball milling without or with a very small volume of solvents, gives smaller size nanoparticles (NPs) and larger surface area, and facilitates their functionalization, which is highly beneficial for antimicrobial applications.

Organogermanium Analogues
One of the most fundamental topics in modern organogermanium chemistry is the study of low-coordinate species, and within this realm, the field of multiply bonded compounds is now one of the mainstreams. It therefore comes as no surprise that the literature covering the latter field is vast. Heteronuclear multiply bonded combinations of germanium with the Main Group elements of groups 13, 15, and 16, >Ge=E13–, >Ge=E15–, and >Ge=E16, respectively, are excluded from the consideration. Moreover, numerous compounds, in which the low-coordinate Ge center is intramolecularly (by n-donor substituents) or intermolecularly (through external donor ligands) coordinated, thus experiencing remarkable electronic perturbation, are also not considered, except for silagermenylidenes >Si=Ge(NHC): and digermanium(0) complexes :Ge0(NHC/or NHSi)=Ge0(NHC/or NHSi):, which otherwise cannot be stabilized for their isolation.

Materials Design for N2O/CO2 Capture and Separation
The adsorption of greenhouse gases (GHG) as a method to reduce their emissions into the atmosphere is an alternative that is easier to implement industrially and cheaper than other existing technologies, such as chemical capture, cryogenic separation, or membrane separation. The vast majority of works found in the literature have focused their efforts on capturing CO2 as it is the largest GHG.

Insights into Si-Si and Si-H Bond
During the last decades, the search for new methodologies for the synthesis of organosilicon compounds have increased due to the multiple applications in industry, in academy, among other areas. Silicon-hydrogen and silicon-silicon bond activation by d-block metals still represent the most important pathways for obtaining molecular entities that contain, witihin their structures, silane motifs. Although the chemistry of Si-H bond activation is under continue development, Si-Si bonds are poorly characterized and less used and thus, disilanes represent good starting precursors because of their stability towards ambient conditions. The present entry will focus on the physicochemical properties of Si-H and Si-Si bonds, some trends and finally highlighting their impact on the synthesis of metal complexes.

All-d-Metal Heusler Alloys
A promising strategy, resulting in novel compounds with better mechanical properties and substantial magnetocaloric effects, is favoring the d–d hybridization with transition-metal elements to replace p–d hybridization. The term given to these materials is “all-d-metal”.

Homotrimeric P2X7 Receptor Imaging Tracers
The homotrimeric P2X7 receptor (P2X7R) is expressed by virtually all cells of the innate and adaptive immune system and plays a crucial role in various pathophysiological processes such as autoimmune and neurodegenerative diseases, inflammation, neuropathic pain and cancer. Consequently, the P2X7R is considered a promising target for therapy and diagnosis. As the development of tracers comes hand-in-hand with the development of potent and selective receptor ligands, there is a rising number of PET tracers available in preclinical and clinical studies. P2X7R antagonists can be broadly subdivided into two categories: those able to penetrate the blood-brain barrier (BBB) and enter the central nervous system, or those remaining peripherally. Commonly linked central nervous system (CNS) P2X7R applications are diseases like Alzheimer’s disease (AD), Parkinson’s disease (PD) or multiple sclerosis (MS), as well as the formation of different types of cancer, i.e., glioblastoma multiforme (GBM). On the other hand, peripherally bioavailable P2X7R antagonists that are not BBB-permeable are attractive candidates for the treatment/diagnosis of lung and breast cancer.
