Experimental Demonstration of Plasmon‐Enabled Monolithic Bragg Reflectors for Infrared Light via Inverse Design

ABSTRACT High‐reflectivity mirrors in the mid‐infrared (MIR) range are essential for next‐generation optoelectronic devices but are still constrained by strain accumulation, poor thermal conductivity, and growth instability of thick multi‐alloy stacks in conventional distributed...

Spin and orbital mixing of edge states in a quantum Hall system proximitized by a superconductor

We investigate the formation and transport properties of chiral Andreev edge states in a two-dimensional quantum Hall system proximitized by a superconductor. By numerically modeling the system using the Bogoliubov-de Gennes equations, we analyze the non-local conductance and tra...

Interface-controlled flexural and shear strengthening of reinforced concrete beams with prefabricated eco-designed ultra-high-performance fibre-reinforced concrete

This study investigates an ultra-high-performance fibre-reinforced concrete partially refined by industrial by-products (recycled steel fibres and spent refinery catalyst), denoted Eco-UHPFRC, as a material for strengthening RC beams. Twenty-four beams were examined in four setup...

Influence of Furfuryl Alcohol on the Cross-Linking Process of Selected Industrial Phenol-Formaldehyde Resins

Furfuryl alcohol (C5H6O2, FA) is commonly used as a modifier for phenol-formaldehyde (PF) resins and has been reported to influence their curing behavior and processing performance. Comparative analysis of commercial resin systems with and without FA suggested that the presence o...

Functionalization of Metal-Enriched Pleurotus Biomass with γ-Poly-Glutamic Acid for Cytoprotective and Antimicrobial Wound Care

Objectives: Chronic wound dressings require active components that support moisture management, biocompatibility, and local bioburden control. Therefore, in this study, freeze-dried biomass of Pleurotus ostreatus (Po) and Pleurotus djamor (Pdj) was cultivated in vitro under miner...

Turbocharging small and medium enterprises growth: Sustainable finance strategies for Indian entrepreneurs

Small and Medium Enterprises play a significant role in the development of a country's economic ecosystem through their contribution towards employment generation, industrial growth and innovation. In India, SMEs are central to the Viksit Bharat 2047 goal, and their long-term com...

Analysis of Inductor Model Sufficiency in High-Frequency Power Electronics

This paper presents a comprehensive analysis and optimization framework for power inductor models used in power electronics applications. A methodology is proposed to identify inductor models with the minimum number of elements sufficient to accurately reproduce current waveforms...

Annual Balance of Energy Biomass in Poland: Supply and Emissions from Combustion Versus CO2 Uptake During Biomass Growth

Climate change shifts governments’ focus to introducing policies that decrease the impacts of GHGs (among other emissions) generated by the energy production industry. Biomass is regarded as a net-zero emission source of renewable chemical energy, but analyses show that this is n...

Multi-Sensor Monitoring of Underground Heritage Sites: A Case Study of the Dragon’s Den Cave and St. Kinga’s Chapel in Poland

Long-term structural health monitoring of underground heritage sites is challenging because of high humidity, limited accessibility, complex geological conditions, and aggressive saline environments. This study presents the implementation and long-term assessment of an integrated...

The microstructure and some properties of the novel biomedical ZrTiFe alloy subjected to high-pressure torsion deformation

Abstract Zr- and Ti-based alloys, due to their excellent mechanical, physical, and biological properties, are increasingly used as biomaterials. Although these alloys have been used in medical applications for over 60 years, several issues remain associated with their use in this...

Impact of relative humidity and PIV seeding on the electro-aerodynamic performance of needle-to-ring ionic fans

Abstract Electrohydrodynamic (EHD) fans represent a viable solid-state alternative to conventional thermal management, addressing the demand for miniaturized, silent, and vibration-free cooling in modern electronics. While Particle Image Velocimetry (PIV) is widely utilized for a...

The Impact of Test Conditions and Lay-Up Configuration on SEA in Carbon–Epoxy Tubes

This article presents the effect of test velocity and the percentage of unidirectional (UD) and woven (WF) fibers on specific energy absorption (SEA). Composite tubes with an internal diameter of 20 mm were fabricated using five prepreg layers. Progressive crushing of the specime...

Digital Asset Adoption and Regional Digital Inequality: Descriptive Evidence from the United States, EU-10, V4, and IMT-GT

Background Digital asset adoption varies substantially across regions despite improvements in digital infrastructure. This study examines whether digital infrastructure, financial inclusion, and regulatory clarity are associated with regional differences in digital asset adoption...

Organ specific chrysanthemum biochar for circular waste reuse and sustainable plant production

Abstract Biochar (BC), a low-cost, carbon-rich material produced from a wide variety of biomass sources, is gaining increasing attention in horticultural practice. There is little research on the use of chrysanthemum residues in BC production, especially in the circular productio...

Direct loading of cylindrical WST specimens for Mode I rock fracture energy evaluation: a proof-of-concept study

This study presents a proof-of-concept assessment of an alternative loading configuration for evaluating Mode I rock fracture energy using cylindrical Wedge Splitting Test (WST) specimens subjected to direct tensile opening at the specimen groove. The system uses a simple shear-t...

Submultiplicative polynomials in combinatorics

Abstract For normalized sequences $$\left( g(n)\right) _{n\in \mathbb {N}}$$ g ( n ) n ∈ N we consider recursively defined polynomials $$P_n^g(x)$$ P n g ( x ) . In this paper we study their submultiplicative property, viewed as a Bessenrodt–Ono type inequality for the partition...

Association of the 5-item modified frailty index and chronological age with postoperative length of stay after CRS–HIPEC: a single-centre cohort study

Frailty assessment may inform selection for cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS–HIPEC), but its association with hospitalization in functionally selected patients remains uncertain. To evaluate the association of the 5-item modified frailty i...

Impact of R/NIR irradiation of blood on selected hemostatic parameters during and after cardiopulmonary bypass in pigs

Cardiopulmonary bypass (CPB) is associated with significant hemostatic disturbances. Red/near-infrared (R/NIR) light, also known as low-level light therapy (LLLT), may attenuate these effects. This study investigated the impact of R/NIR irradiation on selected hemostatic paramete...
