In the next decade, separation science will be an important research topic in addressing complex challenges like reducing carbon footprint, lowering energy cost, and making industrial processes simpler. In industrial chemical processes, particularly in petrochemical operations, separation and product refining steps are responsible for up to 30% of energy use and 30% of the capital cost. Membranes and adsorption technologies are being actively studied as alternative and partial replacement opportunities for the state-of-the-art cryogenic distillation systems. This paper provides an industrial perspective on the application of membranes in industrial petrochemical cracker operations. A gas separation performance figure of merit for propylene/propane separation for different classes of materials ranging from inorganic, carbon, polymeric, and facilitated transport membranes is also reported. An in-house-developed model provided insights into the importance of operational parameters on the overall membrane design.

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.

The contributions of academic drug discovery are well characterised in the US context but less well understood elsewhere. This paper provides a UK perspective, focusing on the activities of Drug Discovery Units (DDUs). These units have established themselves as coordinators of translational research, working at the early stages of the drug pipeline to link up the academic and industry capabilities needed to take drug candidates towards the market.

Changes in water, energy, and food (WEF) trade patterns may reshape water circulation patterns, leading to potential water supply and demand risks. Analysis of virtual water risk transmission characteristics and driving factors from the perspective of WEF trade is highly important for alleviating the risk of water shortages and promoting the efficient use of resources. In this paper, a set of methods for quantifying risk transmission values is constructed on the basis of China's interregional input-output model, and the key paths of interregional virtual water risk transmission caused by WEF trade are identified using innovative methods.

Person-centered planning has been shown to benefit people with disabilities and their quality of life. However, we have little knowledge of how person-centered planning can benefit staff and administration within a group home organization, as well as the extent to which it results in changes to organizational practices and procedures, as well as perceptions of people with disabilities. In this qualitative study, we explored the perspectives of organizational employees, an affiliating behavioral consultant, and residents with intellectual and developmental disabilities, taking into consideration key insights from person-centered planning consultant-coaches, to understand the effects of a person-centered planning initiative on the group home organization.

Microkinetic modeling of heterogeneous catalysis serves as an efficient tool bridging atom-scale first-principles calculations and macroscale industrial reactor simulations. Fundamental understanding of the microkinetic mechanism relies on a combination of experimental and theoretical studies. This Perspective presents an overview of the latest progress of experimental and microkinetic modeling approaches applied to gas-solid catalytic kinetics.
