Biodegradable Blown Film Composites from Bioplastic and Talc: Effect of Uniaxial Stretching on Mechanical and Barrier Properties

Macromolecular Materials and Engineering, 2023
As public awareness about climate change grows, there is an increase in the research on bioplastic packaging films. This is the first‐ever scientific report on uniaxially stretched biobased‐polybutylene succinate‐co‐adipate (BioPBSA) and talc (15 and 25 ...

Photocatalytic Degradation of 2,4-Dichlorophenol by TiO2 Intercalated Talc Nanocomposite

International Journal of Photoenergy, 2019
Novel nanocomposites have been prepared by intercalating TiO2 nanoparticles into talc. The nanocomposites have been verified by X-ray diffraction (XRD) from the appearance of a characteristic diffraction peak of TiO2.

3D Printed Polypropylene‐Based Multifunctional Skin‐Core Structures for Thermal Conductivity

Polymer Composites, EarlyView.
SKin‐core structure highlights the thermal conduction properties. ABSTRACT In this work, polypropylene (PP)‐based filaments for Fused Filament Fabrication (FFF) containing boron nitride (BN) and talc (T) were developed, aiming at formulating multi‐material 3D printed parts showing thermal conductivity and balanced mechanical properties.

Synergistic Effects of Carbon Additives and Supercritical CO2 on Cell Morphology and Thermal Insulation of Extruded Polystyrene Composite Foam

Polymer Engineering &Science, EarlyView.
This study demonstrates how sc‐CO2‐assisted extrusion foaming of PS with GNP and FG additives enhances thermal insulation performance through controlled dispersion and cell morphology. Improved thermal insulation is achieved by controlling the additive loading and pressure conditions to optimize nucleation and CO2 diffusion.

Serous Ovarian Cancer Caused by Exposure to Asbestos and Fibrous Talc in Cosmetic Talc Powders - A Case Series.

Journal of Occupational and Environmental Medicine, 2019
OBJECTIVE Asbestos is a known cause of ovarian cancer. We report 10 cases of serous ovarian cancer among users of Johnson & Johnson (J&J) asbestos-containing "cosmetic" talc products.

Nucleation and Clarification of Polyamides With Supramolecular Additives

Journal of Polymer Science, EarlyView.
We demonstrate the synthesis and use of a novel class of supramolecular additives based on bisurea derivatives, which act as efficient nucleating and clarifying agents for semicrystalline thermoplastic polyamide 6 (PA6). These additives are able to induce the crystallization of PA6 already at a concentration of 0.02 wt.%.

Polymer‐clay nanocomposite hydrogels with multiple responses to multiple stimuli

Responsive Materials, EarlyView.
Multistimuli‐responsive polymer‐smectite nanocomposite hydrogels designed by the polymer network design using functionalized polymer networks, copolymer nanocomposite hydrogel and functionalized smectite are summarized. Abstract Hydrogels are widely studied for their stimuli‐responsive properties.

Effect of Biochar on the Thermal and Dimensional Stability of Poly(Vinyl Chloride) (PVC) Composites

Journal of Vinyl and Additive Technology, EarlyView.
Biochar filler enhances the thermal and dimensional stability of PVC. ABSTRACT This study investigated the employment of biomass‐derived biochar as performance‐enhancing filler of PVC. Mechanical, thermal, rheological, and morphological properties were examined, with calcium carbonate (CaCO3) used for comparison.

An Experimental Study of the Formation of Talc through CaMg(CO3)2–SiO2–H2O Interaction at 100–200°C and Vapor-Saturation Pressures

Geofluids, 2017
The metamorphic interaction between carbonate and silica-rich fluid is common in geological environments. The formation of talc from dolomite and silica-rich fluid occurs at low temperatures in the metamorphism of the CaO–MgO–SiO2–CO2–H2O system and ...

Tracing the origin of Roman mosaic tiles in Aquileia: Petrographic analysis of specimens from the suburbium

Archaeometry, EarlyView.
Abstract This research represents the most extensive characterisation of Roman mosaic tesserae (tiles) from Aquileia, Italy, to date, examining 153 specimens. The study aimed to identify the lithotypes used in mosaics production through a multi‐analytical approach, which included colorimetric analysis, polarised light microscopy and scanning electron ...
