Environmentally Friendly Blowing Agents for Producing Polyisocyanurate (PIR) Foams: Study of the Thermal Conductivity Aging and Mechanical Properties

Nano Select, EarlyView.
HFO leads to PIR foams with the lowest thermal conductivity after 7 years (30 days), being maintained in the foam cells for longer times. HFO constitutes a non‐flammable and environmentally sustainable alternative to replace the hazardous conventional foaming agents in these foams.

Metasomatism and Slow Slip: Talc Production Along the Flat Subduction Plate Interface Beneath Mexico (Guerrero)

Geochemistry, Geophysics, Geosystems, 2023
Talc‐rich rocks are common in exhumed subduction zone terranes and may explain geophysical observations of the subduction zone interface, particularly beneath Guerrero, Mexico, where the Cocos plate subducts horizontally beneath North America and ...

Refractory Spontaneous Pneumothorax in Interstitial Lung Disease Under Pirfenidone Treatment. [PDF]

Respirol Case Rep
Our case illustrates that in the case of refractory pneumothorax in patients with ILD, other methods such as mechanical pleurodesis, in addition to chemical pleurodesis, should be considered, because antifibrotics such as pirfenidone might affect the effectiveness of pleurodesis. ABSTRACT Recurrent pneumothorax associated with interstitial lung disease

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.

Thermal, rheological and morphological properties of poly (Lactic Acid) (PLA) and talc composites

Polímeros, 2014
In this study, composites based on poly(lactic acid) (PLA)/talc were prepared at different compositions by melt mixing in a twin screw extruder. The effect of a nucleating agent, talc, on the crystallization behavior, rheological and morphological ...
