Thermal-economic performance assessment of heat recovery-oriented design of integrated CCHP-H₂ system; multi-objective optimization with LCA and AdaBoost decision-making

Combined cooling, heating, power systems integrated with hydrogen production (CCHP–H₂) can simultaneously supply useful outputs while improving the utilization of fuel and recoverable thermal energy. The present project proposes a methane-fueled CCHP–H₂ configuration integrating...

Multistep synthesis of novel indole–benzimidazole hydrazone hybrids as xanthine oxidase inhibitors: In-Vitro evaluation, molecular docking, MD simulations and DFT studies

This work reports the synthesis of a focused library of indole-benzimidazole hydrazone hybrids ( 17 - 35 ) via a multistep procedure involving thiolation, hydrazination, and Schiff base condensation. The final structures were confirmed using 1 H-NMR, 13 C-NMR, and FT-IR spectrosc...

In situ antibacterial thermosensitive hydrogel as a versatile platform for diabetic wound therapy and molecular monitoring

Chronic diabetic wounds are difficult to manage because of persistent inflammation, impaired tissue regeneration, and high infection risk under hyperglycemic conditions. Microbial colonization further aggravates inflammatory responses and disrupts the normal progression of wound...

Innovation adoption across regions: psychological openness and the early diffusion of digital platforms

Early regional adoption is crucial for platform-enabled innovations because their viability depends on enough people within a region adopting them to generate network effects. Existing research on regional innovation diffusion explains early adoption largely through demographic,...

The first three Kaluza–Klein masses do not uniquely determine the one-loop Wilson-line curvature

We study whether three low-lying fermion masses determine a finite Wilson-line response in a five-dimensional Abelian theory on a circle. A neutral angular field generates a periodic fermion mass profile on a winding minimum of a local energy with two cosine couplings. Together w...

Perspectives on Community-Based Pediatric Obesity Prevention and Management Programs in South Korea: A Qualitative Interview Study of School and Local Public Health Center Providers

Background: Pediatric obesity has increased globally, and South Korea has reported the highest prevalence in East Asia. Despite national policies addressing children's nutrition and health, fragmented governance and overlapping programs may limit their effectiveness. We compared...

Fungal frontiers for sustainability: unlocking the hidden kingdom

Fungi have repeatedly delivered transformative advances across industries, from medicine to food to materials, yet these breakthroughs have emerged from a narrow base of organisms and well-studied systems. Although mycology has taken a big leap forward in the past decades because...

Harnessing Photoexcited-State Pathways in Boron Dipyrromethene for Phototheranostics and Photopolymerization

Abstract Boron dipyrromethene (BODIPY) dyes are widely recognized for their strong visible-light absorption, high fluorescence, and structural modularity. Beyond fluorescence, molecular engineering can redirect their photoexcited states toward distinct photochemical pathways, exp...

Nonlinear Electro‐Optic Visible Photonic Circuits for Solid‐State Quantum Defects

Integrated visible photonic engines for solid-state quantum defects provide a foundation for scalable quantum networks. While miniaturization is advancing, active manipulation remains limited by the difficulty of achieving simultaneous milliwatt-scale visible light generation and...

Income Dynamics and Incident Esophageal Cancer: A Retrospective Cohort Study

BACKGROUND: Although socioeconomic status is a recognized risk factor for esophageal cancer (EC), most studies have examined socioeconomic status at a single time point. We investigated the association between income dynamics and incident EC. METHODS: We analyzed 3,361,091 Korean...

Metabolomic profiling and biomedical potential of adventitious roots derived from a 150-year-old mountain ginseng

Panax ginseng Meyer, sometimes known as Asian ginseng or Korean ginseng, is an important medicinal herb used in traditional medicine and health foods in Korea, China, and Japan. Ginsenosides, also known as saponins, are found in ginseng roots along with polysaccharides, peptides,...

Spatially Complementary In‐Plane Lattice Strain Engineering for Reduced Contact Resistance and Enhanced Ferroelectric Switching in Van Der Waals α‐In 2 Se 3 Ferroelectric Semiconductor Field‐Effect Transistors

ABSTRACT α‐In 2 Se 3 ferroelectric semiconductor field‐effect transistors (FeS‐FETs) offer attractive non‐volatile memory characteristics but are limited by high source/drain (S/D) contact resistance and inefficient ferroelectric polarization switching. Here, we demonstrate a low...

CNT-Mediated Integration of Pd and In2O3 Circumvents Activity–Stability Trade-Off in CO2 Hydrogenation to Methanol

Abstract Metal promotion is a widely adopted strategy to enhance the activity of indium oxide (In2O3) catalysts for CO2 hydrogenation to methanol. However, intimately contacted metal promoters on In2O3 often result in rapid catalyst deactivation, as excessive local H2 supply indu...

When Premium Product Strategy Meets Sustainability: Environmental–Economic Trade‐Offs in Japanese Manufacturing

ABSTRACT Corporate sustainability has become a central concern for business stakeholders, yet little is known about how premium product strategies shape firms' sustainability orientations and performance. Drawing on stakeholder theory, this study examines whether pursuing premium...

Volatile eutectics to tailor crystallization for perovskite optoelectronics

Improvements to the radiative efficiency of halide perovskite thin films are necessary to approach fundamental solar cell performance limits. We tailored perovskite crystallization by leveraging the eutectic interaction between zinc bromide and methylammonium chloride additives....

Circadian misalignment and low-grade inflammation: Failure of temporal gating by the molecular clock

Circadian misalignment, from shift work, recurrent sleep-wake disruption, or mistimed behavioral rhythms, tracks with cardiometabolic disease and low-grade systemic inflammation, yet no single account ties the molecular, animal, and human evidence together. This narrative review...

Not all debt is equal: Debt type, burden, and life satisfaction among urban young adults in Seoul

Young adults in rapidly growing cities face mounting financial pressures from escalating housing costs and limited access to stable employment. This study examines how different debt types and perceived debt burden are associated with life satisfaction among young adults in Seoul...

Stable and efficient n-type scaffolded semiconductor for photocatalytic hydrogen production under tungsten light irradiation

Abstract The production of green hydrogen (H 2 ) is a sustainable strategy to address the current energy crisis without contributing to long-term greenhouse gas emissions. Many powder-based photocatalysts have shown great promise for light-driven H 2 generation; however, in eithe...

School-age Children as the Dominant Source of Inter-seasonal Influenza Circulation in the Republic of Korea, 2022–2025

Background: Influenza circulates at low levels during summer inter-seasonal periods, potentially bridging consecutive epidemics. Which age groups contribute most to this residual circulation is not well characterized. Methods: We analyzed weekly influenza detection rates from the...

SLC39-driven zinc influx orchestrates pleiotropic tumor–immune system cross-talk to establish immune suppression in colorectal cancer

Tumor metabolic programs shape immune evasion; however, the mechanism by which nutrient-transport systems rewire tumor-immune cell interactions remains unknown. We integrated bulk multi-omics, single-cell transcriptomics, spatial profiling, and functional assays for colorectal ca...
