Photocatalytic Desulfurization
Desulfurization of fuels such as diesel, gasoline, kerosene, and jet fuel has been a challenging operation and remains critical to the petrochemical industry. The main naturally occurring sulfur-containing organic compounds (SCCs) are sulfides, disulfides, mercaptans, thiophene (Th) and its derivatives (benzothiophene (BT), dibenzothiophenes (DBTs), 4-methylbenzothiophene (4-MBT), 4,6-dimethyldibenzothiophene (4,6-DMDBT), 3,7-dimethyldibenzothiophene (3,7-DMDBT), and 2,8-dimethyldibenzothiophene (2,8-DMDBT)). The presence of these SCCs in fuels is undesirable since they create problems during refining, namely deactivation of some catalysts and corrosion of equipment. Moreover, sulfur compounds release toxic SOx and cause severe environmental problems: water and air pollution, global warming, ecological instability, as well as the harmful impact on living organisms. Many countries (USA, European Union, Japan, China and so on) have introduced strict standards to limit the content of sulfur in fuels to 10 ppm.

Electrospun Polymer Materials with Fungicidal Activity
There has been special interest in innovative technologies such as polymer melt or solution electrospinning, electrospraying, centrifugal electrospinning, coaxial electrospinning, and others. Applying these electrokinetic methods, micro- or nanofibrous materials with high specific surface area, high porosity, and various designs for diverse applications could be created.

Antimicrobial Metallopharmaceuticals with Tridentate Schiff Bases
The azomethine group is the common structural feature of SBs, where the substituents can be alkyl, cycloalkyl, aryl, or heterocyclic groups. The carbon atom of the C=Nimine bond is prone to nucleophilic addition, while the nitrogen atom possesses a highly reactive free electron pair that can form stable complexes with metal ions. SBs are among the most widely used organic compounds, showing a wide range of applications as intermediates in organic synthesis, chemosensors, and polymeric stabilizers, in the food, dye, and pigment industry, as well as as catalysts and, in recent years, for their recognized biological properties. The use of tridentate SBs ligands in different organometallic and coordination complexes containing main-group metals and transition metals has been an option to study the biological activity of new possible metallopharmaceuticals that contribute to increase activity and to counteract the effect of microbial resistance.

Functionalized Carbon-Based Electrochemical Sensors for Food/Alcoholic Beverage Safety
Food is a necessity in people’s lives. Equally importantly, alcoholic beverages are also highly demanded globally due to the indispensable role they play in cultural, social, and ritual events. However, the production of food and alcoholic beverages suffers from a variety of contaminants, such as toxins, pesticides, antibiotic residues, and heavy metals, which are seriously harmful to human beings. These urgent threats have raised the awareness of the need to improve product quality and safety via developing effective, rapid, and economical monitoring and detecting methods. Fortunately, due to their numerous advantages, including high sensitivity, short response time, low cost, and easy portability, electrochemistry sensors have made huge contributions to ensuring the quality of food and alcoholic beverages.

Type I Photosensitizers Based on Aggregation-Induced Emission
Photodynamic therapy (PDT) is emerging as a minimally invasive therapeutic modality with precise controllability and high spatiotemporal accuracy in the field of diseases treatment. PDT mainly relies on the photosensitizers (PSs) to generate oxidative reactive oxygen species (ROS), to play the therapeutic role. Type I photosensitizers, that undergo hydrogen atom abstraction or electron transfer manner and subsequently produce superoxide radical (O2•−), hydroxyl radical (OH•), or hydrogen peroxide (H2O2), etc., is showing more and more prominent advantages, particularly in hypoxic tissues, since type I PSs-involved PDT usually exhibit distinctive hypoxia tolerance. Regarding the diverse type I PSs, aggregation-induced emission (AIE)-active type I PSs are currently arousing great research interest owing to their distinguished aggregation-induced emission and aggregation-induced generation of reactive oxygen species (AIE-ROS) features.

Polypodiopsida and Nanotechnology
The species belonging to the Polypodiopsida class have been part of human culture since the beginning of civilization, often being utilized due to the presence of antimicrobial substances (such as alkaloids, terpenes as tannins, saponins, anthraquinones, cardiac glycosides, etc.). Application of the ferns in nanotechnology is presented with practical examples.

Phytosynthesized Metallic Nanoparticles
Phytosynthesized nanoparticles represent a continuously increasing field of research, with numerous studies published each year. However, with the emerging interest in this area, the quality of the published works is also continuously increasing, switching from routine antioxidant or antimicrobial studies on trivial microbial lines to antibiotic-resistant strains or antitumoral studies. However, this increasing interest has not been not reflected in the studies regarding the toxicological effects of nanoparticles (NPs); this should be a subject of greatest interest, as the increasing administration of NPs in general (and phytosynthesized NPs in particular) could lead to their accumulation in the environment (soil, water and living organisms).
