In the past 15 years, we've experienced an unprecedented series of crises, including financial (2008), health (2020), and most recently the supply chain disruptions and the energy emergency in Europe, caused by the war in Ukraine (2022). On top of that, climate change still poses a serious threat to our lives and our planet. These interconnected challenges create tremendous societal problems and compromise the viability of the chemical industry in an environment of price volatility and high inflation. Thus, the International Union of Pure and Applied Chemistry (IUPAC) has launched a series of actions to tackle this and raise awareness of the role of chemistry in solving our major threats. Since 2019, IUPAC has identified the "Top Ten Emerging Technologies in Chemistry" to connect chemical researchers with industry, bridging the gap between science and innovation, maintaining the current competitiveness of the chemical industry, as well as tackling our most pressing global challenges.

Grouping of chemicals has been proposed as a strategy to speed up the screening and identification of potential substances of concern among the broad chemical universe under REACH. Such grouping is usually based on shared structural features and should only be used for the prioritization objectives. However, additional considerations (as well as structural similarity) are needed, e.

Since its discovery, carbon quantum dots (CDs) have been widely applied in cell imaging, drug delivery, biosensing, and photocatalysis due to their excellent water solubility, chemical stability, fluorescence stability biocompatibility, low toxicity, and preparation cost. However, the low fluorescence yield and poor surface structure limit the application of CDs. Heteroatom doping is considered an ideal method to improve CDs' optical and electrical properties.

In this study, the role of a transition metal complex in improving hydrolysis efficiency during nanocellulose production was analysed. Cellulose nanocrystals (CNCs) were extracted from date seeds by incorporating a copper metal complex during HCl hydrolysis. In contrast to traditional HCl hydrolysis at moderate conditions, which yielded only microcrystalline cellulose (MCC), this approach resulted in the extraction of CNCs with a 10 % improved yield compared to MCC.

Since its emergence, porcine reproductive and respiratory syndrome (PRRS) has caused enormous economic losses to the global swine industry. The pathogenesis of PRRS remains under investigation. The porcine reproductive and respiratory syndrome virus (PRRSV) causes reproductive disorders in pigs and respiratory in piglets, which is a 15 kb RNA virus that encodes 16 viral proteins, most of which exhibit multiple functions during the virus lifecycle.

The powerful antioxidant properties of astaxanthin (AST) face two significant challenges: low water solubility and poor chemical stability. To overcome them, extensive research and development efforts have been directed toward creating effective delivery systems. Among them, the positive synergistic effect between biomaterials can be used to refine the design of delivery systems.
