Metal Corrosion Compounds Induced by Heritage Glass
Many heritage objects consist of glass in contact with metals. By ion exchange with absorbed water, alkaline aqueous films are formed on the glass surface. They contain sodium and/or potassium, hydroxide, and carbonate (uptake of carbon dioxide) ions. These electrolytes induce corrosion while in contact with metal and cause unusual corrosion products.

Green Synthesis of Carbon Nanoparticles from Biomass
Carbon nanoparticles (CNPs) have demonstrated utility in a wide range of biological applications such as imaging, sensing and as surface-coatings. Biomass waste can be derived from either plant or animal matter as a result of processing higher-value materials, for instance leaves from trees as by product from processed wood or paper production. Biomass is abundant: trees, agriculture crops, energy crops, fruits, vegetation, wood, aquatic plants and algae, general municipal waste and animal waste.

Metal-Organic Frameworks in Phototherapy
The use of metal-organic frameworks (MOFs) in the biomedical field has grown significantly in recent years. Due to their distinct properties, including their porous structure, large surface area, and inherent photo-responsive properties, MOFs can be particularly useful in the fields of cancer phototherapy and immunotherapy. MOF nanoplatforms have successfully demonstrated their ability to address several drawbacks associated with cancer phototherapy and immunotherapy, enabling an effective and low-side-effect combinatorial synergistical treatment for cancer.

Surface Functionalization of Magnetic Nanoparticles
The surface functionalization of magnetic nanoparticles (MNPs) has witnessed significant progress recently, revolutionizing their utility in multimodal imaging, drug delivery, and catalysis. This progression, spanning over the last decade, has unfolded in discernible phases, each marked by distinct advancements and paradigm shifts. In the early stage, emphasis was placed on foundational techniques, such as ligand exchange and organic coatings, establishing the groundwork for innovations to come.

Organochloride
An organochloride, organochlorine compound, chlorocarbon, or chlorinated hydrocarbon is an organic compound containing at least one covalently bonded atom of chlorine. The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) provides common examples. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with TCDD being one of the most notorious.

Nitrogen Heterocycles and NRF2 Activation
Several nitrogen heterocyclic analogues have been applied to clinical practice, and about 75% of drugs approved by the FDA contain at least a heterocyclic moiety. Thus, nitrogen heterocycles are beneficial scaffolds that occupy a central position in the development of new drugs. The fact that certain nitrogen heterocyclic compounds significantly activate the NRF2/ARE signaling pathway and upregulate the expression of NRF2-dependent genes, especially HO-1 and NQO1, underscores the need to study the roles and pharmacological effects of N-based heterocyclic moieties in NRF2 activation. Furthermore, nitrogen heterocycles exhibit significant antioxidant and anti-inflammatory activities. NRF2-activating molecules have been of tremendous research interest due to their therapeutic roles in neuroinflammation and oxidative stress-mediated diseases.

Phytocannabinoids, Endocannabinoids and Synthetic Cannabinoids
Generally, the term ‘cannabinoids’ refers to a heterogeneous family of compounds that exhibit activity upon particular human cannabinoid receptors, namely CB1 and CB2. They encompass the natural compounds present in the Cannabis plants, lipid mediators called ECs naturally produced by human cells, as well as by all vertebrates on planet Earth, and the synthetic analogs of both groups designed by scientist, called SCs.

The Lifetime of Organic Light-Emitting Diodes
Organic light-emitting diodes (OLEDs) have emerged as a promising technology for various applications owing to their advantages, including low-cost fabrication, flexibility, and compatibility. However, a limited lifetime hinders the practical application of OLEDs in electronic devices. OLEDs are prone to degradation effects during operation, resulting in a decrease in device lifetime and performance.

Plant Extracts-Based Nanocarriers for anticancer therapy
Nanocarriers enhance the dissolution and bioavailability of drugs and facilitate their targeting effect. Taking the potential toxicity into consideration, the incorporation of natural “green” materials, derived from plants, in the nanocarriers fabrication, improve their safety and biocompatibility. These green components can be used as mechanical platforms, targeting ligands or can play be involved in the synthesis of nanoparticles.
