Flotation Separation of Cassiterite from Calcite Using Low-Molecular-Weight Citrus Pectin as Depressant

open access: yesSeparations
This paper presents the development of an environmentally friendly, small molecular depressant citrus pectin for improving the recovery of cassiterite resources. Citrus pectin extracted from citrus peel was utilized as the depressant, and it demonstrated

Biomaterial-based platforms for cancer stem cell enrichment and study

open access: yesCancer Biology & Medicine, 2021
Cancer stem cells (CSCs) are a relatively rare subpopulation of tumor cell with self-renewal and tumorigenesis capabilities. CSCs are associated with cancer recurrence, progression, and chemoradiotherapy resistance.

Feedback and metal enrichment in cosmological SPH simulations I. A model for chemical enrichment [PDF]

open access: yes, 2005
We discuss a model for treating chemical enrichment by SNII and SNIa explosions in simulations of cosmological structure formation. Our model includes metal-dependent radiative cooling and star formation in dense collapsed gas clumps. Metals are returned

Chemical enrichment from massive stars in starbursts [PDF]

open access: yesSymposium - International Astronomical Union, 1999
The warm ionized gas in low-mass, metal-poor star forming galaxies is chemically homogeneous despite the prevalence of large H II regions which contain hundreds of evolved massive stars, supernovae, and Wolf-Rayet stars with chemically-enriched winds.

A novel molybdenite depressant for efficient selective flotation separation of chalcopyrite and molybdenite

open access: yesInternational Journal of Mining Science and Technology
A novel small molecule depressant (M-DEP) was used to separate chalcopyrite and molybdenite via flotation. The results showed that M-DEP had an excellent selective depression on molybdenite, while had little effect on the flotation of chalcopyrite.

Huff-n-puff experiments of mixed CO2 and formation water for enhanced oil recovery of shale oil in the Subei Basin

open access: yesMeitian dizhi yu kantan
ObjectiveIn the Subei Basin, the depletion-drive development of shale oil following reservoir volume fracturing faces challenges such as rapid production decline and low oil recovery. To address these issues, this study explored an experimental method of

Erratum: The chemistry of transient molecular cloud cores [PDF]

open access: yes, 2005
We assume that some, but not all, of the structure observed in molecular clouds is associated with transient features which are not bound by self-gravity.

Nonstationary-enrichment analysis in uranium enrichment caused by chemical equilibrium.

open access: yesJournal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1988
Linearization of the nonlinear differential equation which describes the motion of uranium isotopes in the enrichment by redox chromatography was attempted. It was attained by change of variables, resulting in the analytical solution. Re-expression of this solution with the original variables, which are physically meaningful, enabled us to be exactly ...
