The Structure and Mechanical Properties of the Surface Layer of Polypropylene Polymers with Talc Additions

Materials, 2020
In the presented work the influence of different 3MgO·4SiO2·H2O (talc) contents in polypropylene samples on the structure, hardness, elasticity, and friction of the surface layer was investigated.

Effect of Ammonium Polyphosphate/Silicate Content on the Postfire Mechanics of Epoxy Glass‐Fiber Composites Using Facile Chocolate Bar‐Inspired Structures

Fire and Materials, Volume 49, Issue 3, Page 329-346, April 2025.
ABSTRACT This study investigates the postfire mechanical properties of epoxy glass‐fiber reinforced composites (EP GFRCs) using increasing concentrations of ammonium polyphosphate (APP) and inorganic silicate (InSi) to modify the char and fire residue.

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

The Rhyming Peg Mnemonic Device Applied to Learning the Mohs Scale of Hardness [PDF]

, 2003
NOTE: This is a large file, 55.7mb in size! This article describes the use of the rhyming peg mnemonic device to teach Moh's scale of hardness. The "pegs" consist of a set of words, each rhyming with a number from one to ten, to which the mineral names ...

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

Geological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Seismic Fault Weakening Due To Thermal Pressurization of Comminution‐Induced Hydrophilic Talc

Geophysical Research Letters
Talc is generally considered to be frictionally stable, yet the mechanochemical effect of extensive comminution along the fault gouge remains poorly understood.

Ionic liquid-decorated Fe3O4@SiO2 nanocomposite coated on talc sheets: An efficient adsorbent for methylene blue in aqueous solution

, 2020
Ionic liquid-modified silica-coated magnetite (Fe3O4@SiO2-IL) nanoparticles were synthesized using co-precipitation, silylation, and substitution routes, and finally immobilized on talc sheets by electrostatic interactions.

Large‐Scale Evaluation of Traditional Chinese Medicines Reveals Potential PPARγ Modulators for Type 2 Diabetes Management

Journal of Clinical Laboratory Analysis, EarlyView.
Identifying novel treatments for diabetic management is always a competitive research topic all over the world. PPAR‐γ is one of the key regulators involved in glucose and lipid metabolism and improves insulin sensitivity and glucose homeostasis. This study investigated the impacts of 639 traditional Chinese medicine (TCM) on PPAR‐γ gene promoter ...
