Post-Functionalized Vinyl-Addition Polynorbornenes as Modular Platforms for Anion Exchange Membranes: Structure–Property Relationships

Abstract Fully hydrocarbon-based anion exchange membranes (AEMs) were developed through a facile post-polymerization strategy using vinyl-addition polynorbornene (VA-PNB) backbones. A high-molecular-weight poly(5-vinyl-2-norbornene) (PVNB) precursor was synthesized via chemoselec...

Self-Monitoring Theranostic Nanomaterials for Biomedical Imaging and Cancer Therapy: Real-Time Visualization of Biodistribution, Payload Release, and Therapeutic Response

Theranostic nanomedicines integrate therapeutic delivery with diagnostic imaging, but many conventional platforms primarily visualize nanocarrier localization and provide limited information on whether the therapeutic payload has been released, the intended treatment mechanism ha...

Third-Harmonic Generation in Crumpled Silicon Nanomembranes

Abstract Silicon nanomembranes provide mechanically compliant devices for strain engineering. Here, we investigate third-harmonic generation in flat and crumpled silicon nanomembranes of 15 and 35 nm using polarization-resolved third-harmonic generation microscopy with ab initio...

Structure-property relationships for catalyst design toward CO2 utilization via dry reforming of methane

Dry reforming of methane (DRM) utilizes CO 2 as a soft oxidant to convert CH 4 into synthesis gas, a versatile feedstock for downstream fuels and chemicals. However, practical CO 2 utilization through DRM is constrained by catalyst deactivation caused by metal sintering and carbo...

Application of LHC gas recuperation systems for methane emission control in livestock housing

Abstract The CH4rLiE (CH4 Livestock Emission) project presents a dry-gas laboratory proof-of-principle for mitigating methane (CH4) emissions in livestock housing. This work investigates the technical feasibility of capturing CH4 at low concentrations by adapting gas recovery sys...

Age-stratified prevalence and associated risk factors of hypertension, diabetes and hypercholesterolemia in Nepal: Insights from the STEPS survey 2019

Background Non-communicable diseases (NCDs) are a major global public health challenge, particularly in low- and middle-income countries such as Nepal. Despite the growing burden of hypertension, diabetes, and hypercholesterolemia, limited evidence exists on age-stratified patter...

Clinical Outcomes of Switching from Prostaglandin Analogs to Omidenepag Isopropyl in Primary Open-Angle Glaucoma and Glaucoma Suspect Patients with Prostaglandin-Associated Periorbitopathy: A Prospective, Multicenter Study

Background/Objectives: Prostaglandin-associated periorbitopathy (PAP) is a common treatment-related burden of prostaglandin analog (PGA) therapy that may compromise long-term glaucoma management. This study evaluated improvement in PAP and changes in intraocular pressure (IOP) af...

Composition-Driven Structural Regulation of Fe-Co Aerogels for High-Current-Density Hydrogen Evolution

Cost-effective alkaline water electrolysis requires non-precious-metal electrocatalysts that sustain the hydrogen evolution reaction (HER) at high current densities while maintaining favorable interfacial kinetics and an accessible electrode structure. Here, Co incorporation was...

Oxygen Vacancy Engineering for Enhanced Remanent Polarization and Memory Window in a-IGZO/HZO Ferroelectric Field-Effect Transistors

Abstract HfO2-derived ferroelectric field-effect transistors (FeFETs) are promising for nonvolatile memory and logic-in-memory applications owing to CMOS compatibility and low-voltage polarization switching. Amorphous InGaZnO (a-IGZO) is attractive for back-end-of-line compatible...

A practical guide to automated test assembly for educational evaluation in health professions: a demonstration using the R package ROI

Automated test assembly (ATA) using mixed-integer programming (MIP) is standard practice in international testing organizations, but detailed and accessible practical guidelines remain scarce for health professions assessment. This study introduces the mathematical foundations of...

Muscle- and Gland-Specific Dosing of Botulinum Toxin in Facial Aesthetics: Review of Dose Ranges, Target Depth, Muscle Thickness, and Neuromuscular or Glandular Anatomy

Botulinum neurotoxin type A (BoNT-A) dosing in facial aesthetics varies across anatomical targets, formulations, and treatment indications. This structured narrative review examined published dose ranges and the potential relevance of muscle thickness, target depth, functional an...

Sex determination through metric analysis of teeth crown

Teeth that are resistant to external stimuli and have little diversity for individuals can be an important identification factor. This study aimed to present a method that can be used easily and accurately to identify individuals using their teeth, specifically to determine their...

Diagnostic performance of the Korean oral frailty screening questionnaire and diagnostic criteria for physical frailty, sarcopenia, and malnutrition: a pilot study

The association between declining oral health and function and the development of frailty, disability, and mortality has been well documented. This study aimed to evaluate the diagnostic performance of the Korean oral frailty diagnostic criteria and screening questionnaire for id...

Microbial Network Signatures Associated With Outcomes of Peri‐Implantitis Therapy

ABSTRACT Aim To investigate the microbial network signatures associated with outcomes following surgical therapy of peri‐implantitis. Materials and Methods Microbiological data from a 1‐year randomised controlled trial of 28 patients (28 implants) were analysed. Based on a compos...

Ultrafast Magneto‐Geometric Control of Terahertz Helicity in Curved Ni Metasurfaces

ABSTRACT Dynamic helicity control in the terahertz (THz) regime is essential for ultrafast polarization optics, chiral spectroscopy, and polarization‐selective photonic devices, yet remains difficult because most THz chiral systems are structurally fixed or rely on slow external...

Dynamic surface reconstruction during oxygen evolution enabled by exsolution in Al-doped LaNiO3 for efficient AEM water electrolysis

Surface reconstruction during oxygen evolution reaction (OER) has been considered a key mechanism governing the catalytic activity and durability of perovskite oxides. However, effective materials design strategies to regulate surface reconstruction remain limited. In this study,...

Effect of Crestal Soft‐Tissue Augmentation Prior to or Simultaneously With Implant Placement on Peri‐Implant Tissue Dimensions: Histological Outcomes of an Experimental In Vivo Study

ABSTRACT Aim To histologically assess the effect of the timing of soft‐tissue augmentation (prior to or simultaneously with implant placement) and the type of grafting material on peri‐implant soft‐tissue dimensions. Materials and Methods Mandibular molars (M1, M2, M3) were bilat...
