AbstractThe study demonstrates a scalable and reproducible method for synthesising graphene oxide (GO) nanosheets from commercial carbon fibres derived from carbonised polyacrylonitrile (PAN) polymer. An exfoliation route with nitric acid allows for the preparation of monolayer GO nanosheets with a consistent thickness of 0.9 ± 0.2 nm, identical to the commercially available GO from mined graphite. The GO nanosheets exhibit distinct circular and elliptical shapes, in contrast to the polygonal and sharp‐edged morphology of commercial GO. An extensive evaluation of acidic solutions and electrical potentials identified a narrow processing window critical for obtaining GO nanosheets sized 0.1–1 µm. An unexpectedly low 5% acid concentration was found to be the most effective, providing a balance between efficient exfoliation through synergistic acidic and electrochemical oxidation. The process provides a high yield of 200 mg of GO per gram of carbon fibre. Advanced characterisation using high‐resolution electron and atomic force microscopy (HR‐TEM/SEM/AFM), Raman spectroscopy, X‐ray photoelectron spectroscopy (XPS), and infrared spectroscopy (FTIR) provided detailed insights into the morphology, thickness, surface functionalisation, and chemical composition of the nanosheets. With its high yield, environmentally sound production, and versatility, the synthesised GO offers transformative potential for large‐scale applications, including energy storage, advanced coatings, high‐performance composites, water purification, and electronic devices.

AbstractSelf‐powered biosensors (SPBs) based on biofuel cells (BFCs) use electrical output as a sensing signal without the need of external power supplies, providing a feasible approach to constructing miniaturized implantable or portable devices. In this work, a novel nanozyme of gold nanoclusters/palladium nanocubes (AuNCs/PdNCs) heterostructure is successfully fabricated to develop an innovatively self‐powered and non‐enzymatic glucose sensing system. The AuNCs/PdNCs with glucose oxidase (GOD)‐like activity exhibits superior electrocatalytic and non‐enzymatic sensing performance toward glucose. The non‐enzymatic BFCs‐based SPBs system, established on the AuNCs/PdNCs (anodic catalyst) and single atomic Fe sites coupled with carbon‐encapsulated Fe3C crystals (Fe3C@C‐Fe SACs as a cathodic catalyst) platform, exhibits an exceptional sensitivity to glucose with 0.151 µW cm−2 mm−1 (3.4 times higher than the PdNCs), outstanding selectivity and robust stability. The outstanding performance of the BFCs‐based SPBs system can be attributed to the synergistic cooperation between the PdNCs and AuNCs.

AbstractTin monochalcogenides SnS and SnSe, belonging to a family of Van der Waals crystals isoelectronic to black phosphorus, are known as environmentally friendly materials promising for thermoelectric conversion applications. However, they exhibit other desired functionalities, such as intrinsic linear dichroism of the optical and electronic properties originating from strongly anisotropic orthorhombic crystal structures. This property makes them perfect candidates for polarization‐sensitive photodetectors working in near‐infrared spectral range. A comprehensive study of the SnS and SnSe crystals is presented, performed by means of optical spectroscopy and photoemission spectroscopy, supported by ab initio calculations. The studies reveal the high sensitivity of the optical response of both materials to the incident light polarization, which is interpreted in terms of the electronic band dispersion and orbital composition of the electronic bands, dictating the selection rules. From the photoemission investigation the ionization potential, electron affinity and work function are determined, which are parameters crucial for the design of devices based on semiconductor heterostructures.

AbstractFerroelectric polymers have drawn tremendous attention in film capacitors owing to their high permittivity and ease of processing. Nevertheless, the energy density of such materials is severely constrained due to inferior breakdown strength. To address this dilemma, a double‐gradient multilayered all‐organic dielectric composite film is proposed, fabricated via a simple layer‐by‐layer solution‐casting process. The experimental results demonstrate that the composite film significantly suppresses the leakage current compared to the pristine films, resulting in remarkable enhancement of the insulation properties. The finite element simulation results further reveal that the optimized electric field distribution induced by the gradient structure and the carrier traps at the interfaces between the adjacent layers play a crucial role in impeding the propagation of the breakdown path. As a result, the developed dielectric film reaches an unexpected breakdown strength of 712 MV m−1 along with a high energy density of 19.68 J cm−3, surpassing the bench‐mark biaxially oriented polypropylene as well as the existing ferroelectric‐based composites reported in the recent works. The synergy of gradient and multilayered structure presented in this work offers a novel perspective and approach for the scalable fabrication of dielectric films with eminent capacitive performance.

AbstractArgyrodites are among the most promising sulfide‐based solid electrolytes (SEs) due to their high ionic conductivity and ductility. However, the poor atmospheric stability of sulfide‐based SEs caused by the side reaction with moisture, which generates toxic H2S gas and degrades its high ionic conductivity and low electronic conductivity, has limited the commercialization of ASSBs. Herein, the preparation of sulfide‐based SEs consisting of a Li6PS5Cl (LPSCl) core and fluoride‐rich LPSCl shell are described using a facial fluorine treatment following an annealing process to improve atmospheric stability. Most importantly, with the benefit of a fluoride‐rich LPSCl shell, the prepared SE exhibits well‐kept low electronic conductivity even after exposure to an atmosphere with 20% relative humidity at 25 °C, resulting in an improvement in electrochemical properties without short‐circuiting. These results indicate that the fluoride‐rich LPSCl shell effectively suppresses side reactions with moisture and mitigates the extent of irreversible side reactions. These experimental results and associated first‐principles density functional theory (DFT) models profoundly understand the enhanced air stability of F‐LPSCl. Full cells employing an air‐exposed F‐LPSCl exhibit an enhanced initial discharge capacity of 168.5 mAh g−1 at 0.05 C, cycling stability at 0.3 C over 500 cycles, and rate capability.

AbstractRationally designing the electrolyte system toward improving the electrochemical performance, especially the rate capability, of sodium ion batteries (SIBs) is very important for accelerating their large‐scale commercialization. Herein, it is shown that by refining the molar ratio of two ether solvents, namely dimethoxyethane (DME) and 2‐methyl tetrahydrofuran (MeTHF), a binary solvent electrolyte system forms a sodium ion solvation structure that facilitates high rate charge/discharge of hard carbon (HC) electrodes. It is demonstrated that the boosted rate capability can be attributed to the enhanced sodium ion transportation and desolvation kinetics, resulting from the participation of weak‐coordinating MeTHF molecule with low steric hindrance in the sodium ion solvation sheath, which weakens the interaction between sodium ion and solvent molecules/anions through electron density regulation at the bond critical points (BCPs). The thin and uniform solid electrolyte interphase film on HC electrodes formed in such an ether‐based electrolyte is also beneficial for improving the rate performance and cycling stability. The results of the present study shed more light on how the electron density engineering at the BCPs in sodium ion solvation sheath affects the rate capability of HC electrodes and promote its practical application prospect in future sodium‐based battery chemistries.

AbstractRuthenium (Ru) –based catalysts have been considered a promising candidate for efficient sustainable hydrogen and chlor‐alkali co‐production. Theoretical calculations have disclosed that the hollow sites on the Ru surface have strong adsorption energies of H and Cl species, which inevitably leads to poor activity for cathodic hydrogen evolution reaction (HER) and anodic chlorine evolution reaction (CER), respectively. Furthermore, it have confirmed that anchoring Lewis acid oxide nanoparticles such as MgO on the Ru surface can induce the formation of the onion‐like charge distribution of Ru atoms around MgO nanoparticles, thereby exposing the Ru‐bridge sites at the interface as excellent H and Cl adsorption sites to accelerate both HER and CER. Under the guidance of theoretical calculations, a novel dispersed MgO nanoparticles on Ru (MgOx‐Ru) electrocatalyst is successfully prepared. In strongly alkaline and saline media, MgOx‐Ru recorded excellent HER and CER electrocatalytic activity with a very low overpotential of 19 mV and 74 mV at the current density of 10 mA cm−2, respectively. More stirringly, the electrochemical test with MgOx‐Ru as both anodic and cathodic electrodes under simulated chlor‐alkali electrolysis conditions demonstrated superior electrocatalytic performance to the industrial catalysts of commercial 20 wt% Pt/C and dimensionally stable anode (DSA).

AbstractCopper hexacyanoferrate (Cu2Fe(CN)6) nanocubes with a homogeneous size under 100 nm are synthesized by self‐assembly from Cu2+ and Fe(CN)63− precursors. Similar to previous reports with catalysts containing Cu and Fe, the objective is to produce a nanoparticle catalyst that can promote glutathione (GSH) oxidation thanks to the Cu contribution, plus some ROS production through Fenton‐like processes fostered by Fe. Unexpectedly, the catalytic activity for GSH oxidation are much higher (≈50%) than those obtained with equal Cu amounts provided as CuCl2. Furthermore, in the presence of GSH concentrations characteristic of the tumor microenvironment, the nanocubes disassembled homogeneously, without a noticeably change of composition. These results suggest that this strong increase of catalytic activity arises from synergistic coordination of the released Cu2+ and Fe(CN)63− ions that facilitate GSH deprotonation, accelerating its oxidation. Given the role of GSH in the nanoparticle disassembly process, a selective action of the catalyst can be obtained: lethal doses as low as 18 ppm of Cu are obtained for U251‐MG cancer cells while healthy fibroblasts are largely spared.

Abstract3D fluorescence super‐resolution imaging technology can reconstruct the 3D structure of biological cells in space, which is crucial for observing the intricate internal structures of cells and studying the organization and function of tissues and organs. However, even with super‐resolution imaging techniques that surpass the diffraction limit, the axial resolution typically only reaches one‐third to one‐half of the lateral resolution. Achieving true axial or 3D super‐resolution imaging of samples remains a significant challenge. In light of this, this review summarizes the research progress in axial super‐resolution imaging techniques, with a focus on the principles, developments, and characteristics of these techniques, and provides an outlook on their future development directions. This paper aims to provide valuable reference material for researchers in the field.

ABSTRACTIn both beef and dairy farming, the water quality (WQ) is of utmost importance, as it can significantly influence various cattle performance indicators (PIs). This study, conducted in Egyptian cattle farms experiencing emerging epidemics, aimed to scrutinize the impact of WQ on PIs. A comprehensive survey, involving 132 farms, was carried out using a questionnaire to identify hygiene‐related risk factors (HRFs) that affect PIs. In parallel, 132 water samples were meticulously collected, subjected to analysis, and statistically evaluated to establish correlations between WQ parameters and PIs. Depending on the studied parameter (pH, total dissolved solids [TDS], hardness, chloride, nitrate, sulphate, total colony count [TCC] and total coliform count [TCFC]), the permissible limits were exceeded in a notable percentage of the water samples (from 13% to 86.3%). These parameters showed a significant correlation (ρ = 0.30–0.64) with feed conversion ratio (FCR) in the case of beef farming, the lowest being for pH (ρ = 0.23). Similarly, significant correlations (ρ = 0.34–0.69) were found with dairy‐fed efficiency, apart from pH, which showed no correlation (ρ = 0). Furthermore, specific WQ parameters statistically emerged as predictors for different PIs. High nitrate was the most influential predictor across all beef and dairy PIs, followed by TDS, hardness, sulphate and microbial count. HRFs such as housing system, bedding type, water source, water tank and pipe type, drinker lining, herd size and cattle breed, demonstrated weak to moderate significant correlation with PIs. To conclude, WQ exerts a considerable impact on cattle PIs with the potential influence of on‐farm HRFs. As a result, it is imperative to consider WQ when formulating rations, implementing alternative hygienic practices, and selecting appropriate water treatment methods for cattle farming.

Abstract

Purpose
To evaluate the safety and efficacy of retrievable scaffold therapy combined with sirolimus-coated balloon angioplasty for treating infrapopliteal artery lesions.

Methods
The DEEPER LIMUS study enrolled Rutherford class 3 to 5 patients with infrapopliteal artery disease. Patients underwent vessel preparation with retrievable scaffold therapy followed by sirolimus-coated balloon angioplasty. The primary safety outcome measure was a composite of all-cause mortality, major amputation, or clinically driven target lesion revascularization at 6 months. Secondary outcome measures included acute vessel recoil, perioperative death, angiographic late lumen loss between post-procedure and 6 months, as well as primary patency, major amputation, change in Rutherford class, and wound healing through 12 months.

Results
The study included 26 patients (mean age 71 years, 62% male, 88% Rutherford 5) with 28 treated infrapopliteal lesions (36% occluded, 54% TASC B/C). Acute vessel recoil, measured in seven patients, was negligible (2.4 mm after treatment vs. 2.3 mm 15 minutes after deployment). A 6-month primary safety event occurred in 11.5% of patients (1 all-cause mortality, 1 major amputation, 1 clinically driven target lesion revascularization). Late lumen loss at 6 months was 0.7±0.7 mm. At 12 months, primary patency was 89.5%, improvement in Rutherford class was observed in 68.2% of patients, 90% of patients were deemed very low/low major limb amputation risk based on Wound, Ischemia, and foot Infection (WIfI) scores, and no additional major amputations or clinically driven target lesion revascularizations were reported.

Conclusions
Retrievable scaffold therapy combined with sirolimus-coated balloon angioplasty demonstrated promising safety and efficacy through 12 months in patients with infrapopliteal artery disease.

Authors: Widmann K. M. , Dawoud C. , Gidl D. , Riss S. 
Published: February 2025

Abstract

Background
Rectocele and intussusception are frequently observed during defecography as potential contributors to obstructed defecation syndrome (ODS). We aimed to describe our initial experience with transanal minimally invasive surgery (TAMIS) mucosectomy with muscular plication, as a novel surgical approach to treat patients with ODS.

Methods
Conducted between August 2021 and October 2023 at the Medical University of Vienna, 11 patients (8 female) were prospectively enrolled and underwent TAMIS mucosectomy with circular mucosectomy and longitudinal muscular plication (internal Delorme’s procedure). Functional outcome and quality of life were assessed by using standardized questionnaires pre- and postoperatively. The median follow up time was 16 months.

Results
In defecography rectal intussusception could be observed in all patients and rectocele was found in nine patients (81.8%). The median age at the time of surgical procedure was 56 years (range 28–76 years). Neither intraoperative nor postoperative complications occurred. The median ODS score decreased from 16 to 11 points (p = 0.171), and four out of five patients (80%) with preexistent fecal incontinence reported improvement of their symptoms postoperatively (80%), though one patient had new onset of fecal incontinence symptoms. No significant changes could be demonstrated in terms of quality life by using the Short-Form Health Survey 12 (SF-12) survey.

Conclusions
Our initial results showed that TAMIS mucosectomy is a safe technique, offering a viable alternative transanal approach for treating symptomatic ODS. Future studies with a larger sample size and a longer follow-up period should enhance the robustness of our preliminary findings.

Abstract
Ethical issues in family businesses become increasingly relevant for businesses, societies and, consequently, organization scholars which manifests in a growing number of publications in the field over the years. Considerable knowledge generated in the area needs to be systematically structured and synthesized. This study reviewed 162 articles published over the last three decades (1989–2023) to map the intellectual and conceptual structure, and future research opportunities in the family business ethics field. Co-citation analysis highlighted four main groups of scholars influencing the field. The bibliographic coupling distinguished five thematic clusters: succession, religion and goodwill, entrepreneurship and innovation, ethical dilemmas, and values and ethical behavior. Sentiment analysis revealed that scholars explored more positive than negative terms associated with family business ethics. Finally, co-occurrence network analysis suggested the emerging keywords and potential research questions, organized into five research themes, for further development of the family business ethics field.

Abstract
Climate change is one of the most complex and time-sensitive crises humanity is facing, thereby driving a quest for more sustainable product alternatives across all sectors. In hygiene-critical sectors like medicine, the development of sustainable materials is imperative because of the predominant use of single use plastics. Polylactic acid (PLA) has emerged as a bio-based alternative for clinical applications because of its degradation profile. To further enhance antibacterial properties and sustainability performance, a novel biocomposite based on PLA with hemp hurd filled with silver nanoparticles (AgNP) was developed. Here we present a life cycle assessment (LCA) based on ISO 14040 and 14044 to evaluate the added value of the antibacterial biocomposite compared to conventional antibacterial materials from an environmental perspective. The environmental impacts are analyzed in comparison to virgin PLA, fossil-based polypropylene (PP) and high-density polyethylene (HDPE) combined in a disinfecting wipes and sterilized application. Our results show that the novel biocomposite has in general higher environmental impacts than its counterparts. Notably, our findings suggest a significant impact derived from high energy demand required for AgNP synthesis. To be able to compete with other materials, the energy demand needs to be minimized, which should be the focus of further research.
