In today's era, nanoparticles (NPs) have become an integral part of human life, finding extensive applications in various fields of science, pharmacy, medicine, industry, electronics, and communication. The increasing popularity of NP usage worldwide is a testament to their tremendous potential. However, the widespread deployment of NPs unavoidably leads to their release into the environmental matrices, resulting in persistence in ecosystems and bioaccumulation in organisms. Understanding the environmental behavior of NPs poses a significant challenge due to their nanoscale size. Given the current environmental releases of NPs, known negative consequences, and the limited knowledge available for risk management, comprehending the toxicity of NPs in ecosystems is both awaiting and crucial. The present review aims to unravel the potential environmental influences of nano-scaled materials, and provides in-depth inferences of the current knowledge and understanding in this field. The review comprehensively summarizes the sources, fate, transport, toxicity, health risks, and remediation solutions associated with NP pollution in aquatic and soil ecosystems. Furthermore, it addresses the knowledge gaps and outlines further investigation priorities for the sustainable control of NP pollution in these environments. By gaining a holistic understanding of these aspects, we can work toward ensuring the responsible and sustainable use of NPs in today's fast-growing world.

Gas bubble evolution is an important phenomenon in many electrochemical processes and it is highly sensitive to the surface properties. Here we visualize the gas bubble dynamics on the surface of different graphene substrates during hydrogen evolution reaction (HER) using atomic force microscopy combined with scanning electrochemical microscopy. The low overpotential and low surface hydrophobicity of few-layer graphene formed on C-phase SiC causes the uniform distribution of hydrogen nanobubbles, which easily depart from the surface during the reaction. Conversely, the high overpotential and more hydrophobic surface of HOPG induces hydrogen bubbles to linger on the surface for an extended duration, leading to its accumulation and the subsequent formation of microbubbles. This in-situ nanoscale electrochemical mapping of hydrogen bubble dynamics provides new insight into electrocatalytic HER that occurs on non-metal electrodes. © 2024 Elsevier Ltd

Based on its functional aspects, the area is divided into two, namely urban and rural areas. Problems related to solid waste are not spared from that areas. However, problem-solving solutions cannot be generalized between the two areas because of the different characteristics of the community. This study took place in Boyolali District, Central-Java, consisting of 192 rural areas and 75 urban areas. Judging from the characteristics of the population, most people in rural areas do not consider the waste management system that is already important. The main reason is the mindset of the community and applicable waste retribution. Rural communities prefer to burn all their waste on their own land rather than having to pay for waste transportation or recycle their waste. Unlike the case with people in urban areas who have followed the pattern of solid waste management carried out by the government. In addition, there are several community groups in urban areas that have begun to actively recycle waste even its still use conventional technology. Therefore, the application of smart waste management, especially smart waste recycling were already applied in districts which closed to the capital region. © 2019 IOP Publishing Ltd.

Dynamic optimization of nonlinear chemical systems - such as batch reactors - should be applied online, and the suitable control taken should be according to the current state of the system rather than the current time instant. The recent state of the art methods applies the control based on the current time instant only. This is not suitable for most cases, as it is not robust to possible changes in the system. This paper proposes a Deterministic Q-Learning method to conduct robust online optimization of batch reactors. In this paper, the Q-Learning method is applied on simple batch reactor models;and in order to show the effectiveness of the proposed method the results are compared to other dynamic optimization methods. The main advantage of the Q-learning method or the proposed method is that it can accommodate unplanned changes during the process via changing the control action;i.e. the main advantage of the proposed method that it can overcome sudden changes during the reaction. In general, we try to maximize the final product obtained or meet certain specifications of the products (e.g. minimize side products). Copyright © 2019, The Authors. All rights reserved.

Studying the real-time dynamics of strongly correlated systems poses significant challenges, which have recently become more manageable thanks to advances in density matrix renormalization group (DMRG) and tensor network methods. A notable development in this area is the introduction of a complex-time evolution scheme for tensor network states, originally suggested for solving Anderson impurity model and designed to suppress the growth of entanglement under time evolution. In this study, we employ the complex-time evolution scheme to investigate the dynamics of one-dimensional spin systems, specifically the transverse-field Ising model (TFIM) and the XXZ model. Our analysis revisits the dynamic critical exponent z of the TFIM and explores the dynamical structure factor in both gapped and gapless states of the XXZ model. Importantly, the complex-time evolution reproduces the results of real-time evolution while mitigating the rapid growth of quantum entanglement typically associated with the latter. These results demonstrate that the combination of complex-time evolution and extrapolation provides a robust and efficient framework for studying the dynamics of complex quantum systems, enabling more comprehensive insights into their behavior. © 2025, CC BY.

Indonesia is an archipelagic country that has a large population. This high population has increased the amount of waste produced every year. Kalimantan is one of the regions in Indonesia that has a small population. However, large amounts of waste were found in the area around the coast of the Karimata Islands. This research goal is to figure out the source of the waste along with the characteristics of the sea current in the vicinity area of the research location. The methodology is carried out in 2 ways, including collecting primary data with the support of citizen science research within the transect method and a hydrodynamic numerical model. This research is on undergoing project, then the initial outcomes prove that hydrodynamic numerical modeling can be used as a tool to determine the source of marine debris and most of the marine debris stranded on Buluh Kecil Island and Genting Island at Karimata Islands. The characteristic marine debris movement is dominated by the north direction sea current, including waste from Vietnam, Malaysia, and Thailand.

The prototype Large-Sized Telescope (LST-1) of the Cherenkov Telescope Array Observatory (CTAO) is in commissioning phase at the Observatorio del Roque de Los Muchachos at 2200 m a.s.l. in La Palma (Canary Islands, Spain). LST-1 is a 23-m diameter telescope and is the first of four that will compose the LST part of the CTAO Northern array. The LST subarray is optimized to provide the best sensitivity for gamma rays in the 20 GeV - 200 GeV energy range. The MAGIC telescopes, which are located approximately 100 m from the LST-1, is operating as a two 17-m telescope stereoscopic system for more than 14 years. LST-1 and MAGIC routinely perform joint observations of gamma-ray sources to exploit the potential of the three-telescope system. This contribution describes the analysis pipeline and evaluates the performance of the system using Monte Carlo simulations and data on the Crab Nebula. The sensitivity achieved during joint observations with MAGIC and LST-1 is about 30% higher than that of MAGIC alone. © Copyright owned by the author(s) under the terms of the Creative Commons.

An Analysis of Coal Post-Mining Land for Agricultivation Uses (A Case Study on PT ABK in Kutai Kartanegara District, East Kalimantan Province)

引用

IOP Conference Series: Earth and environmental science 2022年第1期950卷

作者： Ansahar S R P Sitorus H Hardjomidjojo E I K Putri Natural Resources and Environmental Management Science Study Program Graduate School of IPB University West Java Indonesia Department of Engineering Faculty of Mining Enginering Kutai Kartanegara University Kutai Kertanegara District Kalimantan Timur Province Indonesia IPB University West Java Indonesia

The characteristics of coal surface mining activity are vulnerable to environmental degradation due to soil excavation, although only causing a lower risk in worker's incidence and economically beneficial as requiring a lower cost than the underground mining method. This study aimed to analyze the types of post-mining land use worth developing for the local community's livelihood around the post-mining land on the concession of PT Anugerah Bara Kaltim (ABK) in Kutai Kertanegara District, Kalimantan Timur Province. The method used was a cost-benefit analysis (CBA). The analysis results indicate that the pepper plant cultivation on the post-mining land within six years produces Net Present Value (NPV) at Rp 49,484,637.00, Benefit/Cost (B/C) Ratio at 1.347, Net B/C Ratio at 2.56, and Internal Rate Return (IRR) at 39.20%. Meanwhile, rice plant cultivation stimulated within six years produces NPV at Rp 8,653,754.00, B/C Ratio at 1.035, Net B/C ratio at 1.3871, IRR at 8,50%. The economic analysis results based on all indicators: NPV, B/C, net B/C, and IRR, demonstrate that the pepper and rice plant cultivation activities are feasible in the coal post-mining land.
