Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.

Screening Surface Modifications to Benzene to Improve Solubility in Hydroxyl‐Terminated Polybutadiene (HTPB)—A DFT Demonstration

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The objective of this paper is to demonstrate the advantage of computationally pre‐screening surface‐modifying material candidates, using density functional theory (DFT), to inform experimental synthesis and formulation efforts. This demonstration focuses on improving the solubility of benzene‐based materials in hydroxyl‐terminated ...

Urban Housing Markets and Sustainability Risk: Empirical Evidence From South African Cities

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite the global shift toward sustainability and rising expectations for socially and environmentally responsible housing, evidence from South Africa's urban markets remains limited and underexplored. This study examines how sustainability‐related vulnerabilities shape downside housing risk across 60 cities between 2002 and 2021.

The association between red blood cell distribution width‐to‐albumin ratio and risk of insomnia: A cross‐sectional analysis of National Health and Nutrition Examination Survey and Chinese clinical data

open access: yesSleep Research, EarlyView.
Abstract Background The red blood cell distribution width‐to‐albumin ratio (RAR) is a novel composite biomarker of inflammation and nutritional status, yet its association with insomnia and underlying mechanisms remain poorly understood. Objective To investigate the association between the RAR and insomnia in two independent cohorts, comprising a ...

Impacts of Change‐Type and State‐Type System Qualities on Complex System Architectures

open access: yesSystems Engineering, EarlyView.
ABSTRACT System qualities, such as scalability, expandability, and reconfigurability, are key requirements of complex systems. Requirements associated with system qualities are important factors in design trade space analyses, but systems engineering design methodologies make only limited use of these qualities, hindering a holistic understanding of ...

Comorbidity Patterns Between Hearing Loss and Symptomatic Dizziness in Middle‐Aged and Older Adults

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To explore the comorbidity patterns between hearing loss and symptomatic dizziness (HL‐SD) in middle‐aged and older adults. Methods This cross‐sectional study used data from the 1999 to 2004 National Health and Nutrition Examination Survey (NHANES). After excluding incomplete data, 2961 participants aged 40–69 were analyzed. Logistic

Toward Silica‐Free Compliance: A Low‐Viscosity Sample Pretreatment Methodology for Crystalline Quartz Quantification in Viscous Pastes

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Crystalline quartz, the most common crystalline silica polymorph, is widely found in industrial products. It is of high regulatory relevance, because its fine fraction, a form of respirable crystalline silica, is classified as an occupational carcinogen, with product‐content thresholds (e.g., 0.1% (w/w) in the European Union) and stringent ...
