Background: Antimicrobial resistance (AMR) is among the most pressing challenges in modern infectious medicine, driving progressive failure of standard antibacterial therapy and rising mortality from infections caused by multidrug-resistant (MDR) pathogens. Antibiotic potentiation through adjuvant compounds capable of…
O-rings made from graphene-enhanced fluoroelastomer (FE/GE) nanocomposites were tested in mechanical seals of centrifugal pumps in high-pressure sour condensates. After 18 months of service, the O-rings remained intact, with no cracks, swelling, or visible damage, demonstrating exceptional durability. Post-field-testi…
The high entropy alloys (HEAs) with body-centered cubic (BCC) structure have been widely demonstrated to exhibit excellent irradiation resistance and hold great promise for nuclear structural applications. By integrating the concept of HEAs with the design of low-activation materials, a novel series of Ti 2 ZrTa x V 0…
Abstract We report the emergence of a weak topological insulator phase in the thin films of the R3m phase of Bi₂Te₃, observed from electrical transport measurements. Conventional Bi₂Te₃ is a strong topological insulator. In contrast, the R3m phase breaks inversion symmetry, thereby inducing anisotropic spin-orbit coup…
This paper introduces the Quantum Matter Rule Emergence (QMRE) framework, a novel approach to understanding the formation of complex material properties, particularly in the context of artificial quantum materials. The central hypothesis of QMRE posits that self-organizing rules can arise spontaneously within the intr…
Abstract The thermoelectric optimization of metallic heavy-fermion systems, such as the YbAl3 Kondo lattice, is fundamentally constrained by an excessively high electronic thermal conductivity (κE) that stems from an inherently high carrier concentration. Herein, we propose an approach to decouple electrothermal trans…
This computational study proposes a novel titanium production process using a quaternary MgCl₂-CaCl₂-NaCl-KCl molten salt for in-situ electrolytic co-deposition of Mg and Ca for complementary reduction of TiO₂. Thermodynamic calculations (ΔG° = -231.0 to -307.5 kJ/mol at 600°C) show Ca deoxidation reaches 20.2 ppm ver…
Abstract The aim of this study was to determine the source of ozone yellowing observed in denim trousers and to identify the most appropriate process flow to minimise it. For this purpose, standard pre‐washing, stone washing, and hypochlorite bleaching processes were applied to denim trousers. Subsequently, the effect…
Abstract There is increasing interest in multifunctional materials for energy conversion devices worldwide. Chalcogenides remain at the center of attraction due to their significant applications in optoelectronics and photovoltaics. In this study, density functional theory is employed to investigate the structural, op…
Abstract Cancer remains a critical global health challenge, leading to millions of deaths worldwide due to its rapid progression and complex resistance mechanisms. However, conventional therapeutic modalities are frequently constrained by tumor hypoxia, heterogeneity, therapeutic resistance, and off-target toxicity, e…
This paper presents a compact, high-performance microstrip tri-band bandpass filter (BPF) based on a cross-coupling structure. By virtue of the structural symmetry, the evenodd mode analytical method based on the ABCD matrix theory is applied to characterize the transmission mechanisms and resonance conditions. Benefi…
Abstract A comprehensive approach is presented for estimating the complete material coefficient matrices of 1-3 piezocomposites. The standard methods usually implemented for piezoceramics can’t be applied directly to 1-3 piezocomposites as there are practical limitations in preparing 1-3 piezocomposite specimens with…
This paper introduces the Dark Matter Information Structure (DMIS) concept, proposing that dark matter possesses not only a mass distribution, represented by ρm, but also an underlying information structure, denoted as IDM. This framework aims to provide a novel perspective on the nature of dark matter, potentially re…
This paper introduces the Local Spacetime Elastic Gradient (LSEG) framework, a novel approach to understanding gravity and spacetime dynamics. The core concept posits that spacetime is not uniformly elastic but exhibits spatially varying elasticity, denoted as [Es(x)]. This gradient in elasticity allows for the compar…
The woodworking internet preaches that bombproof joinery like mortise-and-tenon and through-dovetails are always superior. But this hierarchy ignores a crucial truth: the right joint depends on your application, not just raw strength. Full article: https://david-ohnstad.com/woodworking-joints-strength-myth/
Abstract Nature’s biological machines employ signaling molecules to regulate complex functions, but replicating these functions in artificial systems remains challenging. Here, we report an artificial molecular transducer whose operation is driven by the molecular recognition of exogenous signaling molecules. The tran…

Wounds damage the skin, mucosal membranes, or underlying tissues, disrupting normal structure and function. Natural therapeutic agents, particularly plant extracts, have been widely used in wound management due to their antimicrobial and regenerative properties. Here, we report a novel multifunctional wound dressing b…
Variational Quantum Eigensolvers (VQE) require hundreds to thousands of quantum circuit evaluations to converge from random parameter initialization, severely limiting practical application on near-term NISQ hardware. We investigate whether a 13,156-parameter transformer encoder trained on Hamiltonian-to-optimal-param…
Chemical-looping oxidative dehydrogenation of propane (CL-ODHP) separates hydrocarbon conversion from gas-phase oxygen and uses a redox-active solid as the oxygen source. Here, Ce₁₋ᵧZrᵧOₓ (y = 0–0.50) oxygen carriers were prepared by co-precipitation to examine how moderate Zr doping changes fluorite-lattice structure…
