Properties of Hybrid Perovskite and Polymer Materials
The aim of this work is to investigate the preparation, the optical properties and the stability over time of a colloidal oraganic-inorganic hybrid perovskite (CH3NH3PbBr3)/random copolymer P(MMA-co-DMAEMA) system. Different ratios of perovskite to copolymer were used to study its effect on stability and properties. The optical properties were investigated by UV-Vis and Fluorescence Spectroscopy. Dynamic light scattering was used to determine the size, and the polydispersity of the colloidal hybrid particles; while morphology was investigated by transmission electron microscopy. Photoluminescence decay studies revealed the interaction of the random copolymer with the perovskite. Finally, thin-films were prepared to investigate the optical properties of thin hybrid films was observed under certain conditions.

Dynamic Crosslinking Hydrogel Dressings
One of the most advanced, promising and commercially feasible research issues in the field of hydrogel dressings is to obtain functions to achieve improved therapeutic effects and even intelligent wound repair. In addition to the advantages of ordinary hydrogel dressings, functional hydrogel dressings can also adjust their chemical/physical properties to meet different wound types, respond accordingly, actively create a healing environment conducive to wound repair, and control drug release to provide lasting benefits.

NLC and SLN Nasal Administration
The nasal route has been used for many years for the local treatment of nasal diseases. More recently, this route has been gaining momentum, due to the possibility of targeting the central nervous system (CNS) from the nasal cavity, avoiding the blood−brain barrier (BBB). In this area, the use of lipid nanoparticles, such as nanostructured lipid carriers (NLC) and solid lipid nanoparticles (SLN), in nasal formulations has shown promising outcomes on a wide array of indications such as brain diseases, including epilepsy, multiple sclerosis, Alzheimer’s disease, Parkinson’s disease and gliomas.

Biomedical Application of Carbon Dots
Carbon dots (CDs), which are a new category of carbon nanoparticles that consist of quasi-spherical, discrete fluorescent carbon nanomaterials with a diameter of less than 10 nm, have multiple advantages over semiconductor quantum dots (QDs), including high water solubility, low cost, excellent biocompatibility, chemically inertness, highly tunable photoluminescence and electrochemical luminescence. Because of their unique properties, carbon quantum dots (CQDs) have acquired significance in nano-chemistry, which has resulted in the discovery of CDD applications, especially in biomedical applications.

Date Rape Drug
A date rape drug is any drug that incapacitates another person and renders that person vulnerable to sexual assault, including rape. The substances are associated with date rape because of reported incidents of their use in the context of two people dating, during which the victim is sexually assaulted or raped or suffers other harm. The substances are not exclusively used to perpetrate sexual assault or rape, but are the properties or side-effects of substances normally used for legitimate medical purposes. One of the most common incapacitating agents for date rape is alcohol, administered either surreptitiously or consumed voluntarily, rendering the victim unable to make informed decisions or give consent.

Design and Preparation of Chitosan Hydrogels
Flexible wearable sensors show great potential for applications in wearable devices, remote health monitoring, artificial intelligence, soft robotics, and artificial skin due to their stretchability, bendability, thinness and portability, and excellent electrical properties. Chitosan (CS) is the only alkaline polysaccharide present in nature, which is deacetylated from chitin, and has attracted great interest in the biomedical field due to biocompatibility, non-toxicity, biodegradability, antimicrobial ability and safety. Tremendous efforts have focused on the advancement of chitosan-based hydrogels (CS-Gels) to realize multifunctional wearable sensing by modifying hydrogel networks with additives/nanofillers/functional groups.

SmCo5 Transition Metal Substitution
SmCo5 constitutes one of the strongest classes of permanent magnets, which exhibit magnetocrystalline anisotropy with uniaxial character and enormous energy and possess high Curie temperature. The group of transition metals are sometimes mentioned as the d-block elements due to the fact that d electrons are the external unfilled shells. They are contained within the middle area of the periodic table and are most important for magnetic materials belonging in the fourth period (Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn), with the exception of Nb, which belongs to the fifth. The electron configuration in is (n−1)d1–10 ns2; however, in some cases in intermetallics, the electrons are distributed in a different manner and subshells or partially filled orbitals may arise. Most common cations have a valence of +2 or +3, but there are some that may provide only one electron forming +1 cations or in some cases higher.
