Correlating synthesis, microstructural engineering and thermoelectric performance in BiCuSeO

Layered BiCuSeO chalcogenides have attracted attention as potential oxide thermoelectric material due to inherently low thermal conductivity values, however, accomplishment of simultaneous enhancement in electronic and thermal transport properties remains challenging. In this wor...

Data-Driven Engineering of MnCoMo Electrocatalysts: Predictive Modeling and Experimental Validation for the Oxygen Evolution Reaction

Abstract The development of sustainable green hydrogen through the use of catalytic processes demands a very active and earth-abundant electrocatalyst capable of facilitating the kinetic difficulties of the oxygen evolution reaction. Conventional trial-and-error and solely comput...

Unveiling the Role of Mo in MnCoMo Oxide for Efficient Hydrogen Production via Alkaline Seawater Electrolysis

Abstract Direct seawater electrolysis is a promising strategy for large-scale green hydrogen production, yet it remains hindered by the poor selectivity and durability of earth-abundant electrocatalysts under chloride-rich conditions. Here, we report a systematic investigation of...

Multiscale Computational Insights into Bergenin Encapsulation by Modified γ-Cyclodextrins: Conformational and Energetic Investigations via QM/MM and Molecular Dynamics

Despite bergenin (BER) having significant therapeutic benefits, its medicinal potential is hindered by its low natural abundance and poor aqueous solubility. Through host-guest complexation with cyclodextrins (CDs), this work offers an economical molecular approach to increase th...

Investigation of flow dynamics across transonic compressor stage and inter-stage duct

Abstract The approaching threshold in the design and optimisation of rotating components in gas-turbine engines has drawn attention to the inter-spool duct (ISD) due to its potential to enhance the aerodynamic efficiency of compression systems. The ISD is a crucial passage to del...

Skeletal Modification of Tryptophan Using Cyclic Diaryliodonium Salts via Palladium-Catalyzed Cascade π-Extended Annulative Dual C2–H/N–H Arylation

Abstract We have demonstrated an efficient Pd-catalyzed annulative dual C2–H/N–H arylation reaction involving modification of the tryptophan indole skeleton to phenanthridinyl indole. This is an operationally simple and ligand-free strategy that was extended to biologically impor...

Synthesis of Novel 6-N-Aryl/heteroarylethylimidazo[2,1-b]thiazole-3-carboxamides: Bioisosteric Development of Bacillamide Analogues

Marine microorganisms constitute a prolific source of structurally unique secondary metabolites with diverse biological activities. Bacillamide A (1), a thiazole-containing tryptamide alkaloid, was...

Angular Dependence of Magnetoresistance with Twofold and Fourfold Symmetries and a Large Topological Hall Effect in a Ferrimagnetic Mn2SbBe0.1 Single Crystal

Abstract Ferrimagnetic intermetallics with inequivalent magnetic sublattices host rich magneto-transport properties arising from competing interactions and anisotropy. We report on a Mn2SbBe0.1 single crystal, where interstitial Be tunes the anisotropic response under strong in-p...

Reactive molecular dynamic simulation of water induced iron corrosion and its prevention mechanism

Corrosion of iron and mild steel in water and in chloride media is a costly problem for industry, and it also raises safety concerns. Organic molecules containing heteroatoms are commonly used to control it. In most of the reported work, though, the electronic structure of the in...

Evaluation of mass dog vaccination campaign in Techiman, Ghana

Background Across Sub-Saharan Africa, implementation of mass dog vaccination programmes is frequently constrained by inconsistent vaccine procurement, financing limitations, cold-chain requirements, and weaknesses in distribution systems, rather than complete vaccine unavailabili...

Metamaterial assisted hybrid response from frequency selective surface roll off and leaky wave resonator integrated antenna for underground applications

Abstract In emerging era of wireless technologies such as cognitive radio, wireless sensor networks etc., designing effective low frequency antennas < 1000 MHz and specifically < 700 remains a significant challenge due to its poor (often negative) gain and severely limited bandwi...

Sustainable Irrigated Agriculture Pathways for Ghana

This study applied Ghana’s Climate, Land, Energy and Water systems (CLEWs) modelling framework, underpinned by the Open-Source Energy Modelling System (OSeMOSYS), to assess irrigated-agriculture pathways over 2022–2063. Specifically, it examined how the most irrigated agriculture...

Role of Aromatic Topology in Hyper-Crosslinked Polymers on CO2 Adsorption and CO2/N2 Selectivity

Abstract Despite extensive studies of hyper-crosslinked polymers (HCPs) for carbon dioxide adsorption and separation, the fundamental role of aromatic precursor topology in governing localized gas confinement and molecular recognition has remained poorly understood. Herein, we de...

Urine-based detection of Leishmania donovani antibodies using recombinant aurora kinase and otubain cysteine peptidase for noninvasive diagnosis of visceral leishmaniasis

ABSTRACT Visceral leishmaniasis (VL) is a fatal neglected tropical disease that requires early and accurate diagnosis to reduce mortality and interrupt transmission. Although parasitological confirmation using splenic aspirates is the gold standard, it is invasive and hazardous,...

Controlled electro-alignment molecular dynamics in a high tilt angle ferroelectric liquid crystal cell

In a high tilt angle ferroelectric liquid crystal (HTAFLC), spontaneous polarization (Ps) minimization leads to the stripe domain formation with respect to the rubbing direction, arising from the smectic layer bending, limiting uniform alignment and hence practicality. A strategy...

RGMEC — Mathematical Structure: Zero-Parameter Structural Interpretation

Relative Gravitational Matter–Energy Confinement (RGMEC) provides a complementary structural interpretation of gravitational time dilation while remaining mathematically identical to the Schwarzschild limit of General Relativity. Compactness C = GM/(Rc²) is identified as the prim...

IL-35 produced by dendritic cells via TIM-3-STAT3 signaling contributes to the development of visceral leishmaniasis

Visceral leishmaniasis (VL), a life-threatening parasitic disease caused by Leishmania donovani (LD), progresses primarily due to profound immunosuppression. However, the molecular and cellular mechanisms underlying this immune dysfunction remain poorly defined. In this study, we...
