The critical minerals industries in Indonesia may pose possible environmental and human health risks due to the release of pollutants into soil, water, and air, as well as the use of materials and energy. This study investigates the possible environmental and human health impacts of Indonesia's nickel, gold, copper, tin, and bauxite mining and processing industries. This study utilizes the latest version of the OpenLCA software, version 2.0, in combination with the Ecoinvent 3.8 database. To evaluate potential environmental consequences and health effects on humans, CML-IA Baseline and Environmental Priority Strategies (EPS) are employed in product development. The EPS system was developed utilizing a hierarchical methodology with the objective of furnishing the product developer with data regarding the financial impact of human health impairment resulting from a particular product development. The production of one tonne of gold, nickel, bauxite, tin, and copper results in the emission of 7.34.E+07, 4.61.E+04, 3.10.E+04, 1.02.E+04, 8.01.E+03 kg CO₂ eq/t, respectively, contributing to global warming. This production is associated with asthma cases of 7.79.E+01 (gold industry), 2.21.E−03 (copper industry), 1.81.E−03 (tin industry), 9.21.E−04 (nickel industry), and 4.71.E−06 (bauxite industry) Personyears/t. Electricity consumption and the release of carbon dioxide are the main factors contributing to global warming. The primary cause of asthma cases is the utilization of fuel oil and electricity. Power plant chimneys can employ various technologies, such as cyclones, bag filters, and scrubbers, to mitigate the release of polluting gas emissions. The critical mineral industry must prioritize handling and governing of steam power facilities to minimize their negative effects on the environment and human health. © 2024 The Authors

The goal of the current research is to identify the possible usage of biosorbent, Gracilaria Corticata (Red Algae), used as an edible seaweed mostly in India is now used in abatement of lead & chromium from an aqueous solution. Batch scale experimental study was conducted to know equilibrium studies, kinetics & thermodynamics behavior of biosorption. The impact of several constraints like agitated time, biosorbent size, pH and dosage, initial concentration of metals, temperature of an aqueous solution were studied. The statistical optimization analysis was also done to generate response surfaces for the sample showing highest uptake capacity using response surface methodology by applying central composite design technique. It is observed that biosorption studies follow pseudo 2nd order kinetic model. The thermodynamic constraints showed biosorption of lead & chromium on the biomass was a spontaneous & endothermic process. As a result of the work showed the suggested bio sorbent could be an actual biomaterial for the elimination of lead ions rather than chromium from contaminated solutions.

Making the nanocomposites of metal oxides or metal sulfides with carbon source materials has a huge impact on the electrochemical determination of toxic chemicals. To determine the adverse side effects of the antibiotics, electrochemical sensors have been used as they can peek into the sensitivity of the drug sample. This work has done the sensitive amperometric evaluation of a chloramphenicol antibiotic by modifying the electrode of tungsten disulfide decorated boron carbide. Here, tungsten disulfide (WS₂) nanosheets and boron carbide (B₄C) materials were synthesized by conventional methods which give a good amount of yield. The composite was prepared by the green and cost-effective sonochemical approach with good morphology. The conductivity of the nanocomposite and the response to chloramphenicol were determined by cyclic voltammetry. The sensitivity, limit of detection (LOD), and the linear range were observed by the highly sensitive amperometric technique. From the amperometric analysis, the prepared nanocomposite shows nominal LOD as a 17.4 nM, a broad linear range (0.025–1134.6 µM), and good sensitivity of 1.52 µA µM⁻¹ cm⁻². Practicability of the modified sensor was studied in food and pharmaceutical samples with adequate recovery performances. Moreover, the modified electrode shows good stability, repeatability, reproducibility, and anti-interfering properties against the array of food and biological interferences. © 2024 Elsevier B.V.

Angewandte Chemie 2023年第27期135卷

Organocatalyzed reversible-deactivation radical polymerizations (RDRPs) are attractive for many applications. Here, we developed photoredox-mediated RDRP by activating (hetero)aryl sulfonyl chloride (ArSO 2 Cl) initiators with pyridines and designing a novel bis(phenothiazine)arene catalyst. The in situ formed sulfonyl pyridinium intermediates effectively promote controlled chain-growth from ArSO 2 Cl, enabling access to various well-defined polymers with high initiation efficiencies and controlled dispersities under mild conditions. This versatile method allows “ON/OFF” temporal control, chain-extension, facile synthesis of different polymer brushes via organocatalyzed grafting reactions from linear chains. Time-resolved fluorescence decay studies and calculations support the reaction mechanism. This work provides a transition-metal-free RDRP to tailor polymers with readily available aromatic initiators, and will promote the design of polymerization leveraged from photoredox catalysis.

Effects of Susceptor Geometry on Gan Growth on Si(111) with a New MOCVD Reactor

引用

MRS Internet Journal of Nitride Semiconductor Research 2020年第1期4卷 316-321页

作者： Gao, Yungeng Gulino, Daniel A. Higgins, Ryan Department of Chemical Engineering and Condensed Matter and Surface Science Program Ohio University Athens USA Condensed Matter and Surface Science Program Ohio University Athens USA

High quality GaN films on AlN buffer layers were grown on Si(111) with a new, commercial, two-injector vertical rotating disk MOCVD reactor (CVD, Inc.). It was found that the geometry of the susceptor greatly affected the structural quality of the epilayers on Si. For the original susceptor geometry, though single crystal GaN films could be obtained, the films were dark gray in appearance with a rough morphology, and the best x-ray rocking curve FWHM was 2.33°. After modifying the susceptor geometry, transparent, mirror-like single crystal GaN films were obtained with the best x-ray rocking curve FWHM being 0.24°. Photoluminescence (PL) and infrared reflectance (IR) spectra of the grown films were compared. The film growth rate was found to increase with decrease of the growth pressure. A 2-D simulation of the flow, heat transfer, and chemical species transport in the reactor showed a more symmetric flow, larger velocity gradient, and lower upward velocity with the modified susceptor, which may be the main reason for the improvement of the structural quality of the films.

Polydopamine (PDA) is a widely used anchoring layer for multiple purposes. While simple to prepare, PDA is characterized by high chemical and topological diversity, which can limit its versatility. Unraveling the formation mechanism and physicochemical properties of continuous confluent layer and adherent nanoparticles on the nanoscale is crucial to further extend the prospective applications of PDA. Utilizing nano-FTIR spectroscopy, we investigate layers of PDA on three different substrates (silicon/silicon dioxide, nitrogen-doped titanium oxide, and gold substrates) at varying times of deposition (ToD). We observed a good correlation between the nano-FTIR and macroscopic FTIR spectra that reflected the changes in the relative abundance of PDA and polymerization intermediates as ToD increased. To gain analytical power, we utilized the principal component analysis (PCA) and extracted additional information from the resulting loadings spectral curves and data distribution in the score plots. We revealed a higher variability of the spectra of ultrathin surface confluent layers compared to the adherent nanoparticles. While the spectra of nanoparticles showed no apparent dependency on either ToD or the substrate material, the spectra of layers were highly affected by the increasing ToD and exhibited a rise in the absorption of PDA. Concomitantly, the spectra of layers grouped according to the substrate material at the lowest ToD point to the fact that the substrate material affects the PDA's initial physicochemical structure. The observed separation gradually diminished with the increasing ToD as the PDA physicochemical structure became less influenced by the substrate material. © 2023, The Authors. All rights reserved.

Heat transfer operations are very common in the process industry to transfer a huge amount of thermal energy, i.e., heat, from one fluid to another for different purposes. Many fluids are used as heat transfer fluid (HTF), in which water is the most common HTF due to its high specific heat, availability, and affordability. However, conventional HTFs, including water, have a lower thermal conductivity, which is the most critical thermophysical property, hence decreased heat transfer efficiency. The addition of solid particles of highly thermally conductive material, specifically at nano-size, i.e., nanoparticles NPs, result in nanofluid NF, which has evolved over the last two decades as efficient HTF and have been investigated in a wide range of applications. Among NPs, graphene (Gr) based materials have shown very high potential as NF due to the very high thermal conductivity up to 5,000 W/m.K, hence higher thermal conductivity NF. This work aims to thoroughly discuss the thermophysical properties of Gr-based NFs, including thermal conductivity, heat capacity, density, and viscosity. The discussion focus on the thermophysical properties as it is the ultimate determinator of the heat transfer characteristics of the HTF, such as the convective and the overall heat transfer coefficient as well as the heat transfer capacity of the NF. The discussion expands to the relative enhancement in such thermophysical properties reaching up to a 40% increase in thermal conductivity, as the most critical thermophysical property. The discussion shows that Gr-based NF has a much higher thermal conductivity relative to widely studied metal oxide NF and at much lower content, and lower density and viscosity increase, which is critical for determining the pumping power requirements. Critical challenges facing the application of Gr-based NFs such as cost, stability, increased density and viscosity, and environmental impacts are thoroughly discussed with mitigation recommendations given.
