High-entropy alloys (HEAs) have revolutionized alloy design by integrating multiple principal elements in equimolar or near-equimolar ratios to form solid solutions, vastly expanding the compositional space beyond traditional alloys based on a primary element. However, the immense compositional complexity presents significant challenges in designing alloys with targeted properties, as billions of new alloy systems emerge. High-throughput approaches, which allow the parallel execution of numerous experiments, are essential for accelerated HEA design to navigate this extensive compositional space and fully exploit their potential. Here, we reviewed how advancements in high-throughput synthesis tools have accelerated HEA database development. We also discussed the advantages and limitations of each high-throughput fabrication methodology, as understanding these is vital for achieving precise HEA design.

Short-term exposure (typically ranging from a few hours to 7 days) to particulate matter (PM) elicits acute inflammatory responses with significant activation of complement component C5. However, the relationship between PM-induced complement system activation, acute inflammation, and the contributing factors remains unclear. In this study, we aimed to investigate the intensity of acute inflammatory responses, as well as the activation levels of complement C5 and its related products, C5aR1 and C5b-9, following exposure to different types of PM. Acute inflammatory responses and complement activation were assessed in mice intratracheally administered four types of PM: titanium dioxide (TiO₂), diesel exhaust particles (DEP), Asian sand dust (ASD), and ambient PM with an aerodynamic diameter ≤ 2.5 μm (PM2.5). Complement system and inflammatory markers were evaluated by analyzing increased C5 protein levels, C5b-9 deposition, and C5aR1 expression. Additionally, dark-field microscopy and Raman microscopy were used to detect PM components adjacent to infiltrating neutrophils, and elemental composition was quantified using ICP-MS and EDXRF. ASD, DEP, and PM2.5 exposure significantly increased C5b-9 deposition in lung tissues. All PM-exposed groups exhibited substantial upregulation of C5aR1 expression, primarily in neutrophils. Raman spectroscopic analysis revealed Si, K, Mg, Al, and Fe adjacent to infiltrating neutrophils in ASD-exposed lungs. Furthermore, elemental analysis identified Si, Mg, Al, and K as the most potent contributors to complement activation and inflammatory responses. Of the four types of PM, ASD induced the most severe acute inflammatory response and complement system activation. Therefore, ASD-induced complement system activation, driven at least partly by its mineral components, may play a critical role in neutrophil activation and acute pulmonary inflammation. These findings highlight the differential impact of PM types on complement system activati

Liquid metals are commonly used in chemical industries and nuclear reactors. Since liquid metals may be hazardous, they should be handled very carefully. Careless handling might cause an adverse effect and even disasters. Corrosion and pressure can deteriorate the structure that handles the liquid metals. Leakage of liquid metals can result in ecological disasters and can lead to a humanitarian crisis. Early warning systems, detection of the accident, and prompt steps taken after the incident are the three important phases of monitoring. Continuous monitoring and timely detection of risk reduce the impact caused by the leakage of liquid metal. At present, industries have sensors-based detection. This paper proposes an enhanced version of the existing system. Here, continuous monitoring uses sensors, the Internet of things (IoT), and an artificial intelligence-based system. In this paper, the conventional system is integrated with AI to identify indoor and open-air fire situations. This paper discusses different data collected and investigated data from the videos, sensors, other monitoring systems. And the false-positive results are reduced by using the proposed methodology. © 2021 Bharati Vidyapeeth, New Delhi. Copy Right in Bulk will be transferred to IEEE by Bharati Vidyapeeth.

Field electron emission (FEE) has significant applications in high-gradient accelerators, cold cathode electron sources, and high-power electronic devices. However, its microscopic mechanisms and the evolution of material microstructure remain unclear. This research focuses on pure titanium (TA2) with different preferred orientations, combining FEE experimental tests, multi-scale Microstructural characterization, and first-principles calculations to systematically investigate the influence of grain orientation on field emission performance and microstructural evolution. FEE tests show that radial samples with preferential growth along the (0002) plane exhibit higher emission thresholds (240 kV/cm) and maximum sustainable voltages (460 kV/cm). Multi-scale characterization and first-principles calculations reveal that electrons preferentially emit from low work function crystal planes rather than grain boundaries or defects. Based on these findings, a “crystal orientation − phase transformation” model for FEE is proposed, elucidating the corrosion mechanism of titanium microstructure under FEE current, explaining processes such as dislocation generation and migration, phase transformation, and surface craters evolution. This crystal orientation dominated mechanism can be extended to other metallic materials, providing new insights for designing high-performance FEE materials.

In October 2021, Korea announced its mid-century carbon mitigation target of achieving carbon neutrality by 2050, reaffirming its commitment by enhancing its 2030 Nationally Determined Contribution (NDC). This study employs six energy-economic and integrated assessment models to explore net-zero emission pathways and strategies for Korea's power sector, while assessing the associated costs and challenges. The findings underscore the complexity and urgency of this transition, with the power sector playing a pivotal role in balancing the dual challenges of rapidly growing electricity demand and full decarbonization. A shift toward a renewable-dominated power sector emerges as a robust strategy, though it poses unprecedented technological and economic challenges. Large-scale low-carbon technologies, such as carbon capture and storage (CCS) and nuclear power, are identified as crucial solutions to reduce reliance on variable renewable energy sources and mitigate associated costs. Additionally, the study finds that current energy and climate policies are insufficient to meet the mid-century mitigation target, highlighting the urgent need for policy enhancements to bridge the gap and ensure the feasibility of Korea's carbon neutrality goal. © 2025

Deep excavations are necessary in the urban areas to meet the increasing requirements of additional space for housing, recreation amenities, utilities, parking and infrastructure facilities etc. Also, due to space limitations, excavations are often located near existing buildings. Significant unearthing is maintained by structures like traditionally maintaining barriers, sheet load barriers, propped barriers, diaphragm barriers and vertical impermeable barriers, and so on. Diaphragm walls are profound maintenance structures used in basements and very common in deep unearthing in the recent trends. All the above mentioned barriers help to build in significant building's storm cellar, overcrowded urban areas, basement frames of metro rails, hydraulic, and marine frames. Diaphragm barriers can be categorized like versatile frames and firmness is given through an inclusion of the barrier in the basement used like a beam framing. Diaphragm barriers are subjected to large horizontal forces due to earth pressures thereby causing heavy overturning movement at the foundation. Also, these are used as impervious cutoffs in excavations with relatively high levels of water table. Indian code guides plan and improvement for diaphragm barriers, IS 9556-1980 provides proposals for architectural strategy as well as tools. To assess and plan framework, it implies guidelines for fortification strong structures IS 456-2000. The purpose of this article can be an assessment of the design and construction aspects of diaphragm barrier for Underground metro projects. © 2020 Elsevier Ltd. All rights reserved.
