Laser-Induced Breakdown Spectroscopy for Food Quality Evaluation
Laser-induced Breakdown Spectroscopy (LIBS) is becoming an increasingly popular analytical technique for characterizing and identifying various products; its multi-element analysis, fast response, remote sensing, and sample preparation is minimal or nonexistent, and low running costs can significantly accelerate the analysis of foods with medicinal properties (FMPs).

UV-A Photocatalysis in Livestock and Poultry Farming
As the scale of the livestock industry has grown with the increase in the demand for livestock and poultry products, gaseous emissions, an unwanted side effect of livestock and poultry production, are also increasing. Various mitigation technologies have been developed to reduce such air pollution, and the mitigation technologies are divided mainly into “source-based type” (meant to fundamentally reduce the emissions) and “end-of-pipe type” (physicochemical and biological treatment of the output from barns to reduce the release into the environment). Ultraviolet light (UV) can be considered as both end-of-pipe (treating exhaust air from barns) and source-based type (treating air inside the barn).

Iron(II) Mediated Supramolecular Architectures
Supramolecular architectures, which are formed through the combination of inorganic metal cations and organic ligands by self-assembly, are one of the techniques in modern chemical science. This kind of multi-nuclear system in various dimensionalities can be implemented in various applications such as sensing, storage/cargo, display and molecular switching. Iron(II) mediated spin-crossover (SCO) supramolecular architectures with Schiff bases have attracted the attention of many investigators due to their structural novelty as well as their potential application possibilities.

Lanthanoid-containing anilato complexes and lattices
Coordination polymers (CPS) and metal organic frameworks (MOFs) with lanthanide compounds (LN) have attracted more and more attention in the past decade, because they may exhibit gas and solvent exchange and adsorption / absorption, and exhibit interesting magnetic and luminescent properties, so they can be used to prepare optical and magnetic sensors for gases.

Chitosan-Based Particles for Biomedical Applications
Marine-derived chitosan (CS) is a cationic polysaccharide widely studied for its bioactivity, which is mostly attached to its primary amine groups. CS is able to neutralize reactive oxygen species (ROS) from the microenvironments in which it is integrated, consequently reducing cell-induced oxidative stress. It also acts as a bacterial peripheral layer hindering nutrient intake and interacting with negatively charged outer cellular components, which lead to an increase in the cell permeability or to its lysis. Its biocompatibility, biodegradability, ease of processability (particularly in mild conditions), and chemical versatility has fueled CS study as a valuable matrix component of bioactive small-scaled organic drug-delivery systems, with current research also showcasing CS’s potential within tridimensional sponges, hydrogels and sutures, blended films, nanofiber sheets and fabric coatings.

Alpha-Amanitin
alpha-Amanitin or α-amanitin is a cyclic peptide of eight amino acids. It is possibly the most deadly of all the amatoxins, toxins found in several species of the mushroom genus Amanita, one being the death cap (Amanita phalloides) as well as the destroying angel, a complex of similar species, principally A. virosa and A. bisporigera. It is also found in the mushrooms Galerina marginata and Conocybe filaris. The oral -1">50 of amanitin is 100 μg/kg for rats. Unlike most cyclic peptides, amatoxins (and phallotoxins) are synthesized on ribosomes. The genes encoding the proprotein for α-amanitin belong to the same family as those that encode for phallacidin (a phallotoxin).

Non-Road Mobile Machinery Emission Studies
The term Non-Road Mobile Machinery (NRMM) covers a broad range of machinery, with or without bodywork and wheels, that are installed with a combustion engine, either a spark ignition (SI) petrol engine or a combustion ignition (CI) diesel engine, and that are not intended for carrying passengers or goods on the road. The study of NRMM emissions in the literature has largely been overshadowed by their on-road counter parts due to data on NRMM not being as freely available.

Semiconductor Metal Oxide Sensors in Reducing Gases Detection
The sensitivity of semiconductor metal oxide sensors can be significantly increased by using nanostructured sensitive layers based on two-component materials, consisting of metal oxides with different electronic characteristics and chemical properties.

Sphingolipid Pathway in IDH1mut Glioma
The presence of the IDH mutation in glioma raises the possibility that these CNS malignancies could be targeted with metabolic-based therapeutics. Exploration of the role that regulatory lipids, such as sphingolipids serve within the IDH1mut gliomas is limited. Our study incorporates LC/MS lipidomic discovery with an aim to identify vulnerabilities within the sphingolipid metabolism that could be exploited therapeutically. We reveal elevation in certain lipids produced along the sphingolipid degradation pathway for IDH1 mutated glioma cells. Our review of TCGA data from clinical patients reveal a parallel trend for enzymes associated with sphingolipid degradation that correlates to increased survivability in glioma patients. We demonstrate the biostatic effects of treatments which target this pathway via inhibiting sphingosine kinase and exacerbating the imbalance between sphingosine and sphingosine 1-phosphate.

Enhancing Weathering Resistance of Wood
Although weathering is primarily a surface phenomenon, it is an important issue for wood products as it affects their appearance, service life, and wood-coating performance. To encourage the use of wood as a material for joinery and other building components, the results of research into increasing the weathering resistance of wood are extremely significant. The development of weathering protection methods is of great importance to reduce the maintenance requirements for wood exposed outdoors and can have a major environmental impact.
