Synthesis of DOPO‐Containing Melamine Flame Retardant and Its Effect on the Flame‐Retardant Properties of Waterborne Polyurethane

Journal of Applied Polymer Science, EarlyView.
DOPO‐containing melamine flame retardants improve the flame retardancy, droplet resistance and mechanical properties of WPU. ABSTRACT To improve the flame retardancy of waterborne polyurethane (WPU), two novel DOPO‐containing melamine‐based flame retardants were synthesized by combining Schiff bases (derived from p‐hydroxybenzaldehyde ...

Developing Calibration Reference Materials and Standardized Protocols for Reliable DSC of Polyolefins

Journal of Applied Polymer Science, EarlyView.
Standardized protocol for reducing Tm standard deviation. ABSTRACT Differential scanning calorimetry (DSC) serves as a critical analytical tool in the polyolefin industry for quality control and product differentiation. Between 2000 and 2025, 7574 global patent applications referenced DSC data, highlighting its ubiquitous role in the industry.

Comparison of Mechanical Properties of Lignin/High‐Density Polyethylene (HDPE) Composites and Wood/HDPE Composites

Journal of Applied Polymer Science, EarlyView.
Manufacturing process and mechanical testing of lignin polymer composites. ABSTRACT Lignin is a plant‐derived, the second most abundant natural polymer, and a waste byproduct of the pulp industry. Incorporation of lignin into plastic composites using scalable approaches is commercially favored and low carbon‐cost.

Dental fluorosis in the European roe deer (Capreolus capreolus): A review of the pathological changes in the enamel of fluorotic cheek teeth and the abnormal pattern of dental wear in affected dentitions

The Anatomical Record, EarlyView.
Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

The Anatomical Record, EarlyView.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...
