Multilingualism in and out of Films and Stereotypes
Films serve to (re-)create a ‘world’ within the mind of the audience. Additionally, they introduce or reinforce stereotypes portrayed as a reality of the modern world through multiplexity and the strategic use of foreign languages, dialects, and non-native language use, among others. Various concepts of stereotypes can be explored in fiction feature films, especially as film characters are often based on different kinds of stereotypes. Audiovisual texts tend to operate as cultural constructs that reflect and convey certain ideologies within an industry that holds the power to marginalize or belittle voices. Multilingual films highlight the contrasts among and within cultures; hence, they can further exacerbate the marginalization and stereotyping of different cultures and nations, ultimately having damaging effects on society’s perception of different stereotypes, such as race and gender groups, which is shown with the examples from a multilingual film.

Microbial PolyHydroxyAlkanoate Biopolymers
PolyHydroxyAlkanoates (PHAs) fulfil every criterion set out in the definition of a natural polymer or a biopolymer. PHA biopolymers, a group of biopolyesters, are found in nature, and they are biosynthesized using renewable carbon in microbes. PHAs are biodegradable, because nature has the tools to convert them into CO2 and water and about 10% organic fertilizer or humus, the same as in the biodegradation of cellulose or cotton.

Nanostructured VO2 Materials and Modulation of Their Properties
The morphology of VO2 depends on synthesis methods, which are primarily categorized solution- and gas-phase-based synthesis methods. For example, sol-gel process and hydrothermal synthesis are representative solution-based chemical approaches, while pulsed laser deposition (PLD), sputtering method, and chemical vapor deposition (CVD) are gas- or vapor-phase synthesis techniques. In previous reports, various techniques for the fabrication of nanostructured VO2 materials have been described in detail.

Application of Boron Carbon Nitride in Supercapacitors
Supercapacitors are regarded as reliable energy storage devices to alleviate the energy crisis and environmental pollution. However, the relatively low capacitance and low energy density limit the practical application of supercapacitors. In this context, boron carbon nitride (BCN) nanomaterials have been extensively studied due to their chemical and thermal stability, high mechanical strength, as well as tunable bandgap. The specific capacitance and energy density of supercapacitors can be significantly improved by fabricating nanostructured BCN-based electrode materials.

Magnetic Catalysts in Ullmann-Type N-Arylation Reactions
Ullmann-type C–N heterocoupling reactions have been applied for the syntheses of N-arylated amines. Transition metal-catalyzed N-arylations have been recognized as particularly efficient procedures for the preparation of nitrogen-containing aromatic systems. These reactions typically carried out under optimized conditions, have also been found to be suitable for the synthesis of complex molecules with other functional groups, including natural products, drugs, or pharmaceuticals. Most importantly, copper-catalyzed N-arylations have been studied and employed in the total synthesis of biologically active compounds. The construction of fused N-heterocyclic compounds also remained the subject of extensive research because of their potential applications in drug discovery and the development of functional materials.

Metal–Organic Frameworks for Removal of Chemical Warfare Agents
The destruction of chemical warfare agents (CWAs) is a crucial area of research due to the ongoing evolution of toxic chemicals. Metal–organic frameworks (MOFs), a class of porous crystalline solids, have emerged as promising materials for this purpose. Their remarkable porosity and large surface areas enable superior adsorption, reactivity, and catalytic abilities, making them ideal for capturing and decomposing target species. Moreover, the tunable networks of MOFs allow customization of their chemical functionalities, making them practicable in personal protective equipment and adjustable to dynamic environments.
