Determination of Site Occupancy in the M-Pd-Zn (M = Cu, Ag, and Au) γ-Brass Phase by CALculation of PHAse Diagrams Modeling and Rietveld Refinement.

The Pd-Zn γ-brass phase provides exciting opportunities for synthesizing site-isolated catalysts with precisely controlled Pd active site ensembles. Introducing a third metallic element into the γ-brass lattice further perturbs the catalytic active site ensembles. Here, we introduce coinage metallic elements M (M = Cu, Ag, and Au) into the Pd-Zn γ-brass phase and investigate the site occupation factors of each element in the γ-brass lattice.

Analysis of the Deterioration Mechanisms of Tools in the Process of Forging Elements for the Automotive Industry from Nickel-Chromium Steel in Order to Select a Wear-Limiting Coating.

This paper provides a detailed analysis of the operation of representative forging tools (in the context of using various surface engineering techniques) used in the process of the hot forging of nickel-chromium steel elements. The influence of the microstructure and hardness of the material on the durability of the tools is also discussed, which is important for understanding the mechanisms of their wear. The research showed that the standard tools used in the process (only after nitriding) as a reference point worked for the shortest period, making an average of about 1400 forgings.

Development of a new tool to simultaneously measure soil-gas permeability and CO concentration as important parameters for geogenic radon potential assessment.

This study assessed the geogenic radon potential using PECAME, an innovative tool designed to simultaneously measure soil-gas permeability and CO concentration - two key parameters for understanding radon transport in soil. Comparative field studies using the RADON-JOK device in various geological settings in Japan and Poland demonstrate the effectiveness of PECAME. These studies reveal a strong correlation between PECAME and RADON-JOK, with an R value of 0.

Association between vulvar lichen sclerosus and celiac disease in woman.

Objectives: Vulvar lichen sclerosus (VLS) is a chronic inflammatory condition involving mainly the genital area with an undetermined aetiology. Recent studies show that in up to 34% of cases in adult women, VLS coexists with allergies or autoimmune diseases like celiac disease (CD), among others. However, literature data relating strictly to the co-occurrence of celiac disease and Duhring's disease (DH) in patients with VLS are very limited.

Associations vulvar lichen sclerosus with autoimmune thyroid diseases.

Objectives: Vulvar lichen sclerosus (VLS) is defined as a chronic inflammatory skin disease that most often involves lesions on the mucous membranes of the vulva with a tendency to progress to the anal skin. The etiopathogenesis of VLS remains unknown and is likely multifactorial. Data emphasize the role of immunological factors - more than 25% of VLS cases coexist with autoimmune diseases.

This study aims to analyze the impact of examination parameters and patient characteristics on the radiation dose received during DSA to optimize safety and minimize exposure. A retrospective analysis of 251 DSA procedures using the GE Innova IGS 630 dual-plane instrument was conducted.

Negative Reaction Order for CO during CO Electroreduction on Au.

The potential-dependent negative fractional reaction orders with respect to the CO partial pressures were measured for CO electroreduction (COR) on Au under mass-transfer-controlled conditions using a rotating ring-disk electrode setup. At high overpotentials, the CO reaction order approaches -1 due to enhanced CO adsorption on Au, which is supported by kinetic analysis and density functional theory (DFT) simulations. This work illustrates that the CO site-blocking effect cannot be ignored, even on a weak CO-binding metal such as Au in the electrochemical environment.

A gate tunable transmon qubit in planar Ge.

Gate-tunable transmons (gatemons) employing semiconductor Josephson junctions have recently emerged as building blocks for hybrid quantum circuits. In this study, we present a gatemon fabricated in planar Germanium. We induce superconductivity in a two-dimensional hole gas by evaporating aluminum atop a thin spacer, which separates the superconductor from the Ge quantum well.

A novel developmental critical period of orexinergic signaling in the primary visual thalamus.

The orexinergic system of the lateral hypothalamus plays crucial roles in arousal, feeding behavior, and reward modulation. Most research has focused on adult rodents, overlooking orexins' potential role in the nervous system development. This study, using electrophysiological and molecular tools, highlights importance of orexinergic signaling in the postnatal development of the rodent dorsolateral geniculate nucleus (DLG), a primary visual thalamic center.

Nano-Photonic Crystal D-Shaped Fiber Devices for Label-Free Biosensing at the Attomolar Limit of Detection.

Maintaining both high sensitivity and large figure of merit (FoM) is crucial in regard to the performance of optical devices, particularly when they are intended for use as biosensors with extremely low limit of detection (LoD). Here, a stack of nano-assembled layers in the form of 1D photonic crystal, deposited on D-shaped single-mode fibers, is created to meet these criteria, resulting in the generation of Bloch surface wave resonances. The increase in the contrast between high and low refractive index (RI) nano-layers, along with the reduction of losses, enables not only to achieve high sensitivity, but also a narrowed resonance bandwidth, leading to a significant enhancement in the FoM.
