Depressant behavior of tragacanth gum and its role in the flotation separation of chalcopyrite from talc

Journal of Materials Research and Technology, 2019
Guar gum is an effective depressant of talc, but it also has some depression effect on sulfide minerals. To find new selective depressants, the depression effects and mechanisms of tragacanth gum to talc were studied and its role in the flotation ...

Crystallization kinetics of poly(lactic acid)-talc composites

eXPRESS Polymer Letters, 2011
The crystallization kinetics of poly(lactic acid) / talc composites were determined over a range of 0 to 15 wt% of talc. Talc was found to change the crystallization kinetics.

Effects of talc particle size on the non-isothermal crystallization kinetics and activation energy of isotactic polypropylene-based composites

eXPRESS Polymer Letters
This study investigates the non-isothermal crystallization behavior of isotactic polypropylene (iPP) reinforced with two types of talc fillers: micrometric talc (μ-talc) and standard talc (S-talc).

Semi‐Brittle Deformation of Talc at the Base of the Seismogenic Zone

Geophysical Research Letters, 2023
Talc is commonly found in the cores of exhumed faults and may be important to the dynamics of slip in active fault zones. To understand the rheology of talc at conditions relevant to subduction zones, we conducted torsional deformation experiments at ...

Ac‐SDKP modulates apoptosis via HSP27 and the FAS/FASL and mitochondrial axes

Animal Models and Experimental Medicine, EarlyView.
Schematic diagram of Ac‐SDKP regulating the FAS/FASL and mitochondrial apoptosis pathways via HSP27. Ac‐SDKP inhibits HSP27 expression, activates the FAS/FASL pathway and Caspase‐3 signaling, increases Caspase‐8 and Caspase‐3 expression, and induces cell apoptosis.

Upcycling Real‐World Post‐Consumer Polyolefins Plastics Into Light Olefins Via Microwave‐Assisted Processing

Carbon Energy, EarlyView.
Microwave‐driven Ru@α‐Fe2O3 selectively upgrades real‐world post‐consumer mixed polyolefin waste into light olefins with high gas yields and olefin selectivity at markedly reduced temperatures compared with conventional thermal pyrolysis. Strong tolerance of additives and feed heterogeneity highlights an energy‐efficient and scalable route for circular
