Neem mediated silver nanoparticles for reactive orange dye adsorption with statistical optimization and artificial neural network modeling

The uncontrolled discharge of synthetic dyes into aquatic systems poses serious environmental and health hazards to humans and animals. Therefore, green, reusable, and effective adsorbents must be developed for sustainable treatment. This study investigated biosynthesized AgNPs a...

Turbulent holomorphic foliations on compact complex tori and transversely holomorphic Cartan geometry

We define a class of nonsingular holomorphic foliations on compact complex tori which generalizes (in higher codimension) the turbulent foliations of codimension one constructed by Ghys in [12]. For those smooth turbulent foliations we prove that all transversely holomorphic Cart...

Detection of password reuse and credential stuffing: a server-side approach

Abstract The widespread adoption of password-based authentication across diverse digital platforms, has significantly heightened exposure to security threats. Due to memorability constraints, users often reuse passwords across multiple platforms, thereby increasing vulnerability...

Stability of multiple cartels in differentiated markets

Abstract We characterise stable market structures under price competition in differentiated markets when multiple cartels may form – this is a marked departure from the predominant assumption in the existing literature that supposes without further justification that at most one...

Tunable Porphyrin Cage Based on Designed Electric Field for Methane Capture and Oxidation

Abstract Methane is a generic chemical feedstock, and its conversion to methanol can provide an alternative fuel. We herein provide a first-principles-based strategy for designing a catalyst that operates in a synchronized catalytic cycle and efficiently converts methane into met...

Synchronized actuation strategy and study of clap-and-fling phenomenon in hummingbird inspired robot

This study presents the design and development of a hummingbird-inspired robot, engineered to mimic the flight dynamics of a real flapping bird through synchronized flapping. While prior flapping-wing robotic studies have primarily focused on mechanical design or open-loop actuat...

CMAdb: a structurally annotated database of chaperone-mediated autophagy substrates

Chaperone-Mediated Autophagy (CMA) is a highly selective pathway of protein degradation implicated in multiple diseases. The precise role of the pathway under pathological conditions is speculated to be largely governed by the nature of the substrate undergoing degradation. Altho...

Can Domestic Carbon Markets Buffer the Impact of EU Border Taxes? A Stochastic Frontier Analysis of Decarbonization Costs in India’s Energy-Intensive Industries

This study examines the vulnerability of India’s energy-intensive and trade-exposed (EITE) industries to the European Union’s Carbon Border Adjustment Mechanism (CBAM) and evaluates whether a domestic emissions trading system (ETS) can mitigate these risks. Using data from the An...

Time-ResolvedPolymorphism in a Cd-MOF with Dual Applicationsin Iodine Adsorption and One-Pot Tandem Knoevenagel–MichaelCyclocondensation Catalysis

Abstract Metal–organic frameworks (MOFs) are highly advanced porous materials with tunable structures, high surface areas, and multifunctional properties, making them attractive for applications in environmental remediation, gas storage, sensing, and catalysis. In this work, two...

Decoupling Electronic Activation and Pore Connectivity in Acidic Oxygen Reduction on Metal‐Free Biomass‐Derived Carbon Catalysts

Acidic oxygen reduction is often discussed as if catalytic activation and mass transport were inseparable. Here, biomass‐derived carbon was used to examine these contributions through oxidation, ammonia annealing, and KOH activation. The onset potential is associated primarily wi...
