On-Site Detection of Volatile Organic Compounds
Volatile organic compounds (VOCs) are of interest in many different fields. Among them are food and fragrance analysis, environmental and atmospheric research, industrial applications, security or medical and life science. In the past, the characterization of these compounds was mostly performed via sample collection and off-site analysis with gas chromatography coupled to mass spectrometry (GC-MS) as the gold standard. While powerful, this method also has several drawbacks such as being slow, expensive, and demanding on the user. For decades, intense research has been dedicated to find methods for fast VOC analysis on-site with time and spatial resolution. The working principles of the most important, utilized are presented, and researched technologies for this purpose and highlight important publications from the last five years.

Functionalization and Applications
Microcrystalline Cellulose (MCC) is an isolated, colloidal crystalline portion of cellulose fibers, and it is a valuable alternative to non-renewable fossil-based materials. It is used for a large plethora of different fields, such as composites, food applications, pharmaceutical and medical developments, and cosmetic and material industries. The interest of MCC has also been driven by its economic value. In the last decade, particular attention has been driven to the functionalization of its hydroxyl groups to expand the field of applications of such biopolymer.

Metal–Support Interaction Effect
Metal–support interaction (MSI) is considered a key effect of electronic and geometric structures of catalysts on tuning catalytic performance. The oxygen evolution reaction (OER) is a crucial process during energy conversion and storage. MSI describes the influence of the interaction of metals and their compounds on carriers on the catalytic reaction process, especially OER mechanism.

Chitosan-Containing Composite Materials for Adsorption and Catalysis
Composite materials including organic–inorganic systems have drawn special attention due to their enhanced properties such as adsorbents and heterogeneous catalysts. At the same time, large-scale production of environmentally benign functionalized biopolymers, such as chitosan (CS), allows for constantly developing new materials, since CS reveals remarkable properties as a stabilizing agent for metal-containing compounds and enzymes and as an adsorbent of organic molecules.

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.

Thermal Stability of Layered LTMO2
Layered lithium transition metal (TM) oxides LiTMO2 (TM = Ni, Co, Mn, Al, etc.) are the most promising cathode materials for lithium-ion batteries because of their high energy density, good rate capability and moderate cost. However, the safety issue arising from the intrinsic thermal instability of nickel-based cathode materials is still a critical challenge for further applications in electric vehicles and energy storage power stations.

Wall Materials of Peptide Microcapsules
Microencapsulation technology can improve the utilization rate of the active peptides. Microencapsulation technology is a kind of encapsulation technology based on nanocarriers. The microencapsulation of peptides refers to the selection of appropriate wall materials and the use of physical, chemical, or physicochemical methods to embed the active peptides, in order to give play to the advantages of isolating the interaction between the active peptide and the external environment.

Anticancer Small-Molecule Agents Targeting Eukaryotic Elongation Factor 1A
Eukaryotic elongation factor 1A (eEF1A) canonically delivers amino acyl tRNA to the ribosomal A site during the elongation stage of protein biosynthesis. Yet paradoxically, the oncogenic nature of this instrumental protein has long been recognized. Consistently, eEF1A has proven to be targeted by a wide assortment of small molecules with excellent anticancer activity, among which plitidepsin has been granted approval for the treatment of multiple myeloma. Meanwhile, metarrestin is under clinical development for metastatic cancers.
