Gas check prevention during calendering of poly(vinyl chloride) films using poly(caprolactone)‐based additives

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.
Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

Ultra‐processed food supply in hospitals: A cross‐sectional analysis of Australian hospitals using cook fresh foodservices

Nutrition &Dietetics, EarlyView.
Abstract Aim Ultra‐processed foods have been associated with a range of adverse health and environmental impacts, yet their supply in health‐promoting settings like hospitals remains largely unexamined. This study aimed to assess and quantify the proportion of ultra‐processed foods utilised in a sample of Australian hospitals using cook fresh ...

Perception of Dry Air: Links to the Indoor Environment and Respiratory and Allergic Symptoms Among Occupants

Atmosphere
Perceived dry air is a common complaint in indoor environments, yet its health associations and environmental factors related to this perception are unclear. We surveyed 7865 families and measured the indoor environment in 399 dwellings in Tianjin, China,

Emollient Formulations and Skin Barrier Practices in the Context of Eczema and Food Allergy Prevention

Allergy, EarlyView.
ABSTRACT The skin is far from a passive shield; it functions as a dynamic “living barrier” whose structural and immunological integrity is paramount in preventing atopic dermatitis (AD) and the subsequent progression of the atopic march toward food allergy (FA).

The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...
