Study on Flame Retardancy and Mechanism of Talc Composite Foams

Frontiers in Materials, 2021
Under high temperature, aqueous film forming foam extinguishing agent has poor flame retardancy and low fire efficiency. In order to solve this problem, talc was introduced into foam to form composite foam.

Dislocation density and graphitization of diamond crystals [PDF]

, 2002
Two sets of diamond specimens compressed at 2 GPa at temperatures varying between 1060 K and 1760 K were prepared; one in which graphitization was promoted by the presence of water and another in which graphitization of diamond was practically absent.

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.

Upcycling Expired Bismuth‐Drugs as Low‐Cost Practical Precatalysts for Sustainable Multi‐Scenario Formate Electrosynthesis

EcoEnergy, EarlyView.
Expired bismuth‐drugs are innovatively purposed as efficient precatalysts, which enables the electro‐upcycling of CO2 into formate, followed by tandem conversion to benzimidazole, providing a critical proof‐of‐concept for sustainable waste‐to‐value conversion.

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.

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.

Dynamic characteristics and processing of fillers in polyurethane elastomers for vibration damping applications [PDF]

, 2011
Polyurethane elastomers have the potential of being used to reduce vibrational noise in many engineering applications. The performance of the elastomer is directly related to matching the nature of the mechanical loss characteristics to the frequency and

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 efficacy of hydrogel foams in talc Pleurodesis

Journal of Cardiothoracic Surgery, 2020
Background Malignant pleural effusions are a serious complication of many late stage cancers that adversely affect quality of life. Pleurodesis with talc slurry is a standard treatment option, but clinical failures occur, possible due to poor talc ...

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 ...
