A special awareness has been given worldwide to clean the polluted environment. The environment is polluted mainly by greenhouse gases, emissions from transportation fuels, etc. Among them, sulfur compounds emitted from the emission of transported fuels significantly impact environmental pollution. It requires the removal of these sulfur compounds from transportation fuels. Refineries use the hydrodesulfurization (HDS) process to reduce these sulfur compounds from fuels. However, the HDS process requires high hydrogen pressure and temperature, making it cost-effective. An alternative to the HDS process is oxidative desulfurization via solvent extraction, which requires low-temperature operating conditions. In this regard, deep eutectic solvents (DESs) are attractive for researchers to desulfurize transportation fuels via solvent extraction due to their low-cost synthesis method. In our study, DESs were synthesized using phenylacetic acid and salicylic acid as hydrogen bond acceptors (HBAs) and tetraethylene glycol as hydrogen bond donor (HBD) in the mole ratio of 1:2. DESs were characterized by using FTIR spectra. Physico-chemical properties of DESs, such as density, viscosity, and refractive Index, were also measured. The synthesized DESs were performed to extract organosulfur compounds from model fuel and actual diesel. An oxidation study was carried out for model fuel and diesel, followed by solvent extraction using these synthesized DESs. The extraction efficiency for PAA/TTEG(1:2) and SAA/TTEG(1:2) was achieved as 50.16% and 38.89% for model fuel at a temperature of 30oC using a solvent to feed ratio of 1.0 while for diesel, it was 38% and 37%. However, it increased to 77%, 68%, and 54%, 73%, respectively, for PAA/TTEG(1:2) and SAA/TTEG(1:2) when the feedstocks were oxidized. These results showed better extraction performance of DES PAA/TTEG(1:2) than that of SAA/TTEG(1:2) at low-temperature 30oC using extractive combined oxidative desulfurization (ECODS). Hence, the DES synthesized using SAA and TTEG in the mole ratio of 1:2 works better as an extraction solvent for removing the organic sulfur compounds from fuels at low temperatures.
全世界都有一种特别的意识来清洁被污染的环境。环境污染主要是由温室气体、交通燃料排放等造成的。其中，运输燃料排放产生的含硫化合物对环境污染影响较大。它要求从运输燃料中去除这些含硫化合物。炼油厂使用加氢脱硫(HDS)工艺从燃料中减少这些含硫化合物。然而，HDS工艺需要高氢气压力和温度，这使得它具有成本效益。HDS法的另一种替代方法是通过溶剂萃取进行氧化脱硫，这需要低温操作条件。在这方面，深共晶溶剂(DESs)因其低成本的合成方法而受到研究人员的青睐，可以通过溶剂萃取法对运输燃料进行脱硫。本研究以苯基乙酸和水杨酸为氢键受体(HBAs)，四乙二醇为氢键供体(HBD)，摩尔比为1:2合成了DESs。用FTIR光谱对des进行了表征。测定了DESs的物理化学性质，如密度、粘度和折射率。利用合成的DESs从模型燃料和实际柴油中提取有机硫化合物。对模型燃料和柴油进行了氧化研究，然后用合成的DESs进行了溶剂萃取。在温度为30℃、料液比为1.0的条件下，模型燃料对PAA/TTEG(1:2)和SAA/TTEG(1:2)的萃取效率分别为50.16%和38.89%，对柴油的萃取效率分别为38%和37%。PAA/TTEG(1:2)和SAA/TTEG(1:2)经氧化处理后，分别提高到77%、68%和54%、73%。结果表明，在低温30℃条件下，采用萃取剂联合氧化脱硫法(ECODS)， DES PAA/TTEG(1:2)的萃取性能优于SAA/TTEG(1:2)。因此，以SAA和TTEG的摩尔比为1:2合成的DES作为低温脱除燃料中有机硫化合物的萃取溶剂效果较好。

Bushings made of platinum-rhodium alloys are a key component in glass fibre production. While bushings have grown in size and functionality since their introduction in the early 20th century, manufacturing constraints still limit their full potential. Both in terms of design and quality, traditional manufacturing methods such as milling, drilling and welding limit the potential of precious metal bushings. The technical feasibility of the use of additive manufacturing for the production of bushings is greatly dependent on the material properties. For the purpose of this work, an additively manufactured alloy consisting of 90 wt% platinum and 10 wt% rhodium (PtRh10) is investigated with regard to density, electrical resistivity, creep performance and the contact angle of E-glass on the PtRh10 samples.

Sustainability has been one of the main issues in the world in recent years. The decrease of resources in the world, along with the growing world population, and the resulting environmental waste, present a fairly significant problem. As an alternative solution to this problem, insects are put forward as an ideal resource. Due to the enzymes and microorganisms in their intestinal microbiota, the biotransformation processes of insects are capable of converting wastes, organic materials, and residues into valuable products that can be used for various industrial applications such as pharmaceuticals, cosmetics, functional food, etc. Some species of insects are in an advantageous position because of the simplicity of their life cycle and the ease of their production and feeding on organic materials to make them valuable products. Considering the sustainability perspective, utilization of the microorganisms or enzymes isolated from these microorganisms available in the microbiota of insects may allow novel insect-based biotransformation processes that promise a more sustainable world and novel green technologies.

Research in the group led by James Wilton‐Ely focuses on catalysis, imaging and sensing. All of this work involves d- and f-elements and is underpinned by the group’s wide-ranging expertise in synthesis. Collaborations with researchers in engineering, medicine and bioimaging allow these discoveries to be used to address major healthcare and sustainability challenges. Professor Wilton-Ely is the author of more than 100 publications and was the recipient of the 2021 Sir Geoffrey Wilkinson Award from the Royal Society of Chemistry for his work on metal-based carbon monoxide sensing. He has a strong interest in sustainability, having directed the MRes Green Chemistry course at Imperial College for over 12 years (2010–2022). He has published on the use of recovered metals in catalysis (1–5), the catalytic transformation of biomass to platform chemicals (6–11) and magnetically-recoverable nanoscale catalysts (12, 13). Elemental sustainability is a pressing concern for all researchers using precious metals and this has led Wilton-Ely to work with colleagues to explore the potential for using gold (3) and palladium (4, 5) complexes recovered from end-of-life products in catalysis.

Activated carbon (AC) is an effective material for its various environmental and industrial applications. The characteristics and performance of AC is a result of interaction between source and method of preparation. In the current work, AC has been prepared from date seed wastes using microwave heating under nitrogen using basic (i.e., KOH) / acidic (i.e., H2SO4) chemical activating agents. The AC was characterised using XRD, SEM-EDX, TEM and TGA/DSC. XRD patterns of the AC in both the cases exhibited 3 peaks corresponding to the crystalline graphite form of carbon. SEM images of the freshly prepared carbons showed that the samples contained particles of various sizes including both nanoparticles as well as mm-range particles. DSC analysis showed that the samples exhibited endothermic reaction in low temperature ranges until 300 ◦C and exothermic reaction above this temperature. SEM analysis of the AC, separated into three different size ranges, showed significant etching of the surface of the carbon to yield porous structures. The AC produced using H2SO4 showed better adsorption capacity (9.2 g/g) when compared to that produced using KOH (7.7 g/g). We conclude that the AC prepared from dates seeds can find potential application in water purification and oil spill clean-up.

Clean air. It should be a basic right for everyone, yet the World Health Organization estimates that in 2019, ambient air pollution in cities and rural areas caused 4.2 million premature deaths worldwide (1). Heart disease, stroke and pulmonary disease are the key causes of premature deaths related to poor air quality and this burden falls largely on people living in low- to middle-income countries.

Globally, transport is responsible for 23% of energy-related carbon dioxide emissions, and 80% of these emissions are attributable to road transport. Significant transformations - including extensive electrification of the sector - are necessary to achieve the climate change goals. To understand the new energy vehicle (NEV) policy research, we explore the status, knowledge base, and research frontiers of NEV policy research by studying 355 papers collected from the Web of Science Core Collection database. We map NEV policy research trends and knowledge structure development using knowledge domain technology and bibliometric techniques. The knowledge base analysis shows that (1) NEV policy formation and evaluation, (2) policy incentives and consumer adoption, and (3) consumer preferences towards NEV adoption are all essential knowledge foundations in NEV policy research and development. The efficiency of NEV policy, cost-effectiveness of alternative fuel vehicles (AFVs), consumer preferences for NEV adoption, hydrogen energy and fuel cell vehicles, climate policy and CO2 emissions are five main lines of research in NEV policy studies. With the highest publications from Tsinghua University, China is the most active country in NEV policy research. Energy Policy, Sustainability, and Journal of Cleaner Production are the core journals, and energy and fuels and environmental sciences are the core disciplines of NEV policy research. The findings of this analysis help policymakers and researchers to navigate the literature on NEV, provide a clear map of existing works, identify the gaps and recommend promising avenues for future studies.
