Photocatalysis for Air Purification
Photocatalysis since a long time has been recognized  as a eco-technology to fight air pollution. It is focused  on the generation of reactive oxygen species (ROSs) under light on the surface of a photocatalytic material. It could be applied in different manners such as for the purification of industrial polluted air, photoconversion of toxic gas into valuable products, self-cleaning systems, photocatalytic filters, etc. However, it faces some technological issues limiting its wide application in real-world.

Extended Characteristic Polynomial
In the context of molecular topology it is well known the Characteristic Polynomial (ChP) for its important uses in relating the structure with molecular properties of hydrocarbons, as well as a high resolution discriminant for chemical structures. Also it is well known that, as any other topological based descriptor/function, the ChP is blind to the nature of the chemical element and of the chemical bond, both being treated as indistinguishable in the context of the chemical graphs theory. An extension of the Characteristic Polynomial (EChP) is proposed by relaxing the identity matrix and adjacency matrix to contain non-binary based values, by in the same time keeping the meaning of those matrices (identity as collecting information regarding the identity of the atoms in the molecule and adjacency as collecting information regarding the connectivity or bonds in the molecule) and their feature (of being symmetrical).

Chemical Composition on Heating Value of Biomass
Biomass has become an increasingly important resource for energy generation. It is well known that the heating value of lignin is significantly higher (23.26–25.58 MJ/kg) than that of polysaccharides (18.6 MJ/kg), while extractives often have higher heating values (HHVs) over 30 MJ/kg, depending on their oxidation levels. Therefore, the proportions of the chemical components in biomass determine its HHV.

Development of CDK4/6 Inhibitors
CDKs, a family of serine/threonine kinases, regulate cell cycle progression into the four distinct phases G1, S (DNA synthesis), G2 and M, and are crucially involved in the regulation of cell division and proliferation.

Types of Microneedle Arrays
Microneedle (MN) arrays are minimally-invasive devices that can penetrate the stratum corneum, one of the most important barriers for topically-applied drugs, thus creating a pathway for drug permeation to the dermal tissue below. MN arrays can be characterized as: (1) solid, (2) coated, (3) hollow and (4) dissolvable. They can be further categorized based on their mode of drug delivery, and the materials used for their manufacture.

Spins in Semiconductor Nanoparticles
- Spin-dependent phenomena in semiconductors are analyzed starting from a theory of the dynamic nuclear polarization via numerous insightful findings in the realm of characterization and control through the nuclear spin polarization in nanoparticles and their aggregates into microparticles as potential contrast agents for magnetic resonance imaging (MRI) applications.  - Electron spin-dependent process of the photosensitized generation of singlet oxygen in porous silicon (Si) for photodynamic therapy application and design of Si-based nanoparticles with electron spin centers for MRI contrasting for cancer theranostics are discussed.

Delivery Platforms for miRNA-Based Cancer Therapeutics
Restoration of microRNA (miRNA) expression or downregulation of aberrantly expressed miRNAs using miRNA mimics or anti-miRNA inhibitors (anti-miRs/antimiRs), respectively, continues to show therapeutic potential for the treatment of cancer. Although the manipulation of miRNA expression presents a promising therapeutic strategy for cancer treatment, it is predominantly reliant on nucleic acid-based molecules for their application, which introduces an array of hurdles, with respect to in vivo delivery. Because naked nucleic acids are quickly degraded and/or removed from the body, they require delivery vectors that can help overcome the many barriers presented upon their administration into the bloodstream.

Olive Biophenols Oleuropein and Hydroxytyrosol
Oleuropein (OLE) and hydroxytyrosol (HT) are olive-derived phenols recognised as health-promoting agents with antioxidant, anti-inflammatory, cardioprotective, antifungal, antimicrobial, and antitumor activities, providing a wide range of applications as functional food ingredients. HT is Generally Recognised as Safe (GRAS) by the European Food Safety Authority (EFSA) and the Food and Drug Administration (FDA), whereas OLE is included in EFSA daily consumptions recommendations, albeit there is no official GRAS status for its pure form.

Njangsa
The term Njangsa refers to an oily seeds tree, Ricinodendron heudelotii, found in tropical West Africa. It is also known as Munguella (Angola), Essessang (Cameroon), Bofeko (Zaire), Wama (Ghana), Okhuen (Nigeria), Kishongo (Uganda), Akpi (Côte d'Ivoire), Djansang, Essang, Ezezang and Njasang. Two varieties of the tree species are recognized R. heudelotii var. heudelotii in Ghana and R. heudelotii var. africanum in Nigeria and Westwards.
