Bicyclo[1.1.0]butane Carboxamides to N-Heterocycles via a Strain Release-Enabled Nickel(II)–Carbene Intermediate

Abstract We report the conversion of bicyclo[1.1.0]butane carboxamides into N-heterocycles via strain release, enabling the generation of a novel class of Ni(II)–carbene intermediate and utilizing it for Ni(II)–carbene alkyne metathesis reactions for cyclopropanation and [4+2] cy...

Investigation on the combined effect of thermal cycling and corrosion behavior on pulsed laser spot-welded Al-Cu joints for battery applications

Laser spot-welded Al Cu joints are widely used in battery interconnects, but their long-term reliability under severe service conditions is less understood. Therefore, this study investigates the combined effects of thermal cycling and corrosion on pulsed laser spot-welded Al Cu...

Modeling of wetting-state evolution in polypropylene-stearic acid functionalized nanostructured superhydrophobic coatings

Superhydrophobic coatings often lose their water-repellent properties after repeated abrasion and environmental exposure, creating a need for reliable methods to predict coating durability. This study developed a machine learning-based framework to predict the water contact angle...

Strain‐centric approach for design of confined core concrete in the columns of short and regular RC frames under cyclic tests

Abstract The cyclic testing of two full scale regular and short column irregular frames has been carried out under large deformations. The load‐deformation hysteresis behavior of the frames has been obtained along‐with strain‐deformation profile of the core concrete at the plasti...

KJac: Constraint-Aware NAS for Learned Optimization

This preprint presents KJac, a zero-training neural architecture search proxy for learned optimization in constrained optimization settings. The study evaluates Jacobian-based architecture scoring across linear projection, convex quadratic programming, QCQP-style constraints, and...

Microstructural Evaluation of Cement Mortar Modified with Treated Wastewater under Varying Mixing and Curing Conditions

ABSTRACT Water scarcity impedes access to safe drinking water for billions and hampers global development initiatives. Conservation and reuse of potable water in concrete or mortar production is of great interest to fostering sustainable resource management in the construction in...

Employing 4‐Amino‐3,5‐bis(aminomethyl)‐1,2,4‐triazole for the Development of Thermally Stable Energetic Salts With Reduced Sensitivity

ABSTRACT Achieving an optimal balance between energy and stability remains a fundamental challenge in high‐energy‐density materials (HEDMs). Additionally, from a practical perspective, it is highly desirable to develop energetic materials via fewer and more efficient synthetic st...

Intelligent Purchase Order Generation with AI

This white paper presents a comprehensive functional and technical framework for applying artificial intelligence to purchase order generation and lifecycle management. It explains how AI, natural language processing, retrieval-augmented generation, business rules, enterprise dat...

Phosphine‐Free NNN Bis‐Iminopyridine Supported Zinc(II) Catalysts: A Sustainable Platform for C─C Bond Formation Reactions via Borrowing Hydrogen Approach of Primary Alcohols

ABSTRACT In this study, we present a methodology for direct C─C bond formation using renewable primary alcohols as alkylating agents, catalyzed by base metal‐derived Zn(II) complexes. We utilized two well‐defined phosphine‐free NNN bis‐iminopyridine pincer ligands (L1 and L2) for...

Between Lipstick and Widow’s White: Female desire and gendered ageism in contemporary Bollywood

Aging women in Bollywood have long been confined within a narrow repertoire of archetypes, among them the suffering widow, the stern matriarch, and the self-effacing grandmother, figures defined not by individuality or desire but by moral authority, self-sacrifice, and patriarcha...

Causal Pathways of Agricultural Drought Development in Semi-Arid Regions using NDVI-based Vegetation Stress Proxies

Climate change is increasing the frequency and intensity of extreme events, including droughts, floods, and compound events. Agricultural drought remains difficult because it is shaped by multivariate interactions among climatic, hydrological, and vegetation-related variables. Al...

Unloaded wires-based simple biasing circuit for varactor-controlled metasurfaces

This paper introduces a varactor-loaded reconfigurable metasurface designed for discrete beam steering, a feature crucial for many applications such as smart radio environments. Initially, MATLAB is used to determine the meta-atom impedances that yield the desired reflection unde...

Seismic Risk Assessment of Dry‐Jointed Concrete Voussoir Arch in Highway Bridge

Topologically interconnected dry‐jointed concrete voussoir arch (CVA) bridge is an emerging bridge typology in India for the construction of highway bridges. This study focuses on seismic risk assessment of a CVA bridge to evaluate its viability across various seismic zones in In...

Impact of the Perform, Achieve, and Trade scheme on decarbonizing Indian industrial production: a PSM DiD approach

Bureau of Energy Efficiency (BEE) of India launched the Perform, Achieve, and Trade (PAT) scheme in 2012 to improve energy efficiency in key energy-intensive industrial sectors. These efficiency improvements were expected to save between 11% to 16% of industrial energy consumptio...

Hydrationas a Structural Switch: Controlling MagneticCoupling and CO2 Photoreduction in Transition-Metal HalidePerovskites

Abstract Transition-metal halides are of particular interest because their partially filled d-orbitals, containing unpaired electrons, give rise to distinctive magnetic and electronic properties. Notably, hydration can act as a structural switch, inducing substantial modification...
