Turning Nd‐Fe‐B Swarf Into High‐Value Bulk Feedstocks via Sustainable Hydrogen Plasma: From Rare‐Earth Oxides to Metals and Hydrides

ABSTRACT Rare‐earth permanent magnets (REPMs) are crucial for electric vehicles, wind turbines, and other high‐efficiency electric motor systems. However, their production is energy‐intensive, and global recycling rates are below 0.2%. Machining swarf is the main industrial waste...

Unraveling Condensation Frosting through Controlled Experiments and Complex Networks

Abstract Condensation frosting is ubiquitously observed in cold countries and various industrial applications, ranging from refrigeration to aerospace systems. In recent years, there has been growing interest in using superhydrophobic and other nanoengineered coatings to delay fr...

Simulating Chemical Reaction Dynamics Using Sample-Based Quantum Diagonalization: A Quantum-Centric Supercomputing Approach

Abstract Quantum computers offer the potential to simulate chemical systems beyond the capabilities of classical computers. However, current quantum computing approaches to ab initio molecular dynamics (AIMD) and vibrational analysis largely rely on the Variational Quantum Eigens...

Fluctuating diffuse-interface simulations of vapor nucleation: Effects of wall superheat, wettability, chemical heterogeneity, and nanoscale topography

Surface modification affects both vapor formation and the heat transferred from a heated wall. These effects must be considered together when assessing surfaces for boiling applications. This study compares the effects of wall superheat, uniform wettability, chemical patterning a...

Development and cyclic performance of a small-fastener connection for cold-formed steel framing

The use of cold-formed steel (CFS) sections as the primary load-carrying members in low-rise residential and industrial buildings is on the rise. The literature reports that the lateral strength and performance of commonly used CFS stud-wall frames are predominantly limited by fa...

Three-Dimensional Concrete Printing in the Construction Industry: Landscape, Challenges, and Future Opportunities

Abstract The adoption of three-dimensional concrete printing (3DCP) has been transforming the construction industry, offering unique design flexibility and efficiency that conventional methods struggle to match. Despite its potential, a critical lack of research exists for nonmat...

Motivation, work, and mobility: developing a process framework of employee turnover intentions in Indian nonprofits

Purpose This study aims to explore the mechanisms associated with employees’ turnover intentions in Indian non-profit organisations (NPOs). Existing employee turnover research provides limited understanding of how individual, organisational, and sector-level dynamics relate to tu...

Biopolymer Silica Hybrids as Superior Nanocarriers for Anticancer Drug Delivery

Abstract Liposomal carriers are widely used for anticancer drug delivery due to their biocompatible nature in the biological milieu. Liposome-based drugs often face premature leakage, uncontrolled release, and insufficient control over long-term drug availability. Here, we presen...

A residual weighted physics informed neural network for forward and inverse problems of reaction diffusion equations

Physics-Informed Neural Networks (PINNs) constitute an effective deep learning approach for solving partial differential equations (PDEs). In this work, we propose a Residual-Weighted Physics-Informed Neural Network (RW-PINN), a new method designed to enhance the accuracy of PINN...

Methodology for Modeling and Seismic Analysis of Four Buildings Representative of Bagan’s Monumental Heritage

This paper presents a comprehensive methodology for assessing the seismic vulnerability of four historic monuments in Bagan, including analysis of their architectural and structural characteristics, an evaluation of their behavior in past earthquakes, and finally finite element (...

An ″α-Methylsulfone″ Transfer Agent: Synthesis and Application of γ-Ketosulfones

Abstract An operationally simple, metal-free one-pot method for the synthesis of γ-ketosulfone from ketone has been developed using aryl/alkyl sulfonyl hydrazide-formaldehyde as an ″α-methylsulfone″ transfer agent. This one-carbon elongation method, promoted by a TFA-morpholine s...

Microbial communities on station and train surfaces in Chennai Metro: insights into urban transit microbiome

ABSTRACT Urban public transport systems, particularly metro networks, serve as key hubs for microbial transmission, yet the urban microbiome in densely populated regions like India remains poorly characterized. Understanding these environments is crucial for public health, especi...

Copper(II)/4‐Dimethylaminopyridine‐Mediated Oxidative Cyclization in Low‐Melting Mixtures: Access to Cyclopropane‐Fused Aza‐Heterocycles

A simple and efficient one‐pot approach has been developed for the stereoselective synthesis of 3‐azabicyclo[n.1.0]alkane derivatives, employing a low–melting mixture (LMM) composed of choline chloride (ChCl) and N , N ‐dimethylurea (DMU). This green and sustainable protocol faci...

Towards sustainable 3D concrete printing: influence of waste foundry sand on rheology and printability of OPC–LC2 systems
