Temporal differentiation of biophilic elements and architectural forms in classroom built environments: evidence from mass-univariate ERP analyses

Purpose Biophilic design has been proposed as a cognitively supportive strategy in educational built environments (BEs); however, its neural mechanisms remain understudied. This study examined event-related potentials (ERPs), providing robust sub-second temporal cognitive dissoci...

Functionalized WS2 Electronic Nose for Volatile Organic Compound Mixture Recognition via Chemically Informed Transformer Learning

Abstract Accurate detection and discrimination of volatile organic compounds (VOCs) in complex environments using chemiresistive sensors remains a major challenge, mainly due to overlapping responses (cross-sensitivity) and environmental interferences. In this study, we have deve...

Basal Plane Passivation of Ti 3 C 2 T x MXenes Through Prussian Blue Analogue Nanoparticles Anchoring for Efficient and Selective Electrochemical Ammonia Synthesis

ABSTRACT Two‐dimensional (2D) MXene‐based materials have emerged as promising electrocatalysts for aqueous nitrogen fixation. However, their performance is limited by inactive basal planes, weak N 2 adsorption, and hydrophilic surface terminations that hinder N 2 binding and prom...

Magneto‐Photoactivated Gold Plasmonic Nano‐Islands and Quantum Dot Assemblies for ppt‐Level NO 2 Detection

ABSTRACT The intrinsic instability and limited chemical reactivity of metal nanoparticles have long restricted their direct integration in chemiresistive gas sensing. Here, we present a highly selective, tunable, ultra‐stable, and ultra‐sensitive NO 2 sensor derived from gold nan...

Biomimicking Mechanical Properties of Human Skin: A State-of-the-Art Review

Artificial skin simulants that reproduce the mechanical response of human skin are important for surgical training, device evaluation, impact assessment, and ballistic testing. Although in vivo and ex vivo characterisation methods for human native skin are physiologically relevan...

Concealment and Consumption: Rethinking Menstrual Products Through Social Marketing

Background Menstrual product use is a routine part of women’s lives, yet it continues to be shaped by silence, stigma, and affordability pressures. Much of the existing literature treats menstruation primarily as a question of hygiene and access, health inclination and adolescent...

Diagnosing Data Quality Gaps across Decision Levels: A Semiotic Framework for Highway Pavement Management

Abstract The rapid digitalization of highway infrastructure has created large volumes of data, yet it remains unclear how effectively this information supports decisions across organizational levels. This paper develops a multidimensional, semiotic-based framework for assessing d...

Interfacial Engineering with Amphiphilic Cationic Polymers: Role of Alkyl Chain Length in Biofilm Suppression and Corrosion Protection

Abstract Biofilm formation promotes microbiologically influenced corrosion (MIC) in marine environments, demanding coatings that can resist bacterial adhesion and corrosion simultaneously. Herein, we report amphiphilic cationic polymer coatings based on quaternized poly(2-(dimeth...

Waste Textile-Derived Carbon Integrated with Mixed Metal Oxides for Flexible Supercapacitor Electrodes

Abstract With the rapid growth of electronic and wearable devices, sustainable energy-storage solutions based on waste-derived materials have attracted significant attention. However, high recycling cost and limited energy-storage performance of many waste resources hinder their...

Heavy metal induced cellular proteostasis failure promotes neurodegeneration and therapeutic opportunities

Exposure to heavy metals is a significant environmental risk factor for neurodegenerative diseases. Persistent exposure to heavy metals including lead, mercury, cadmium, manganese, copper, and arsenic are all examples of non-biodegradable, bioaccumulative toxicants that can cross...

First-Principles Insights into Surface and Ligand Effects in Stoichiometric HgTe Quantum Dots

Abstract HgTe quantum dots are promising colloidal infrared semiconductors for photodetection, imaging, and optoelectronics because their electronic structure can be tuned from the short-wave to mid-infrared. Despite this technological promise, how the electronic structure of ult...

Entropy stable numerical schemes for divergence diminishing Chew, Goldberger & low equations for plasma flows

Chew, Goldberger & Low (CGL) equations are a set of hyperbolic PDEs with non-conservative products used to model the plasma flows, when the assumption of local thermodynamic equilibrium is not valid, and the pressure tensor is assumed to be rotated by the magnetic field. This res...
