Leaching of rare earth elements with sulfuric acid from bastnasite ores / Выщелачивание редкоземельных металлов серной кислотой из пород, содержащих фторкарбонаты / Rastvaranje elemenata retkih zemalja sumpornom kiselinom iz ruda koje sadrže fluorokarbonatni mineral [PDF]

Vojnotehnički Glasnik, 2018
Dissolution of rare earth elements from bastnasite ores was studied using sulfuric acid at the atmospheric pressure. The one step strategy with sulfuric acid was studied further and the results showed that filtering difficulties do not happen for the ...

Formation and application of hydrogen in non-ferrous metallurgy

Vojnotehnički Glasnik, 2023
Introduction/purpose: Hydrogen is the most abundant element in the universe (75 % by mass) and the lightest element (with a density of 0.00082 g/cm3) which consists of only one proton and one electron. Because of its presence in many different forms such

The Potential of Deconstruction in Buffalo, New York [PDF]

, 2007
Building deconstruction is not a novel idea but represents an ancient practice reinvented for our modern era. Deconstruction is an environmentally friendly (yet fiscally remunerative) alternative to traditional building demolition.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Determinants of Trade in Recyclable Wastes between Developing and Developed Countries [PDF]

This paper examines the trade volume of recyclable wastes. In particular, we analyze the trade from developed countries to developing countries. The reason is that, when a recycling process is separated from the production process of final goods or/and ...

Concentration and Separation of Scandium from Ni Laterite Ore Processing Streams

Metals, 2017
The presence of a considerable amount of scandium in lateritic nickel-cobalt ores necessitates the investigation of possible processing alternatives to recover scandium as a byproduct during nickel and cobalt production.

Stochastic Approach to Enantiomeric Excess Amplification and Chiral Symmetry Breaking

, 2006
Stochastic aspects of chemical reaction models related to the Soai reactions as well as to the homochirality in life are studied analytically and numerically by the use of the master equation and random walk model. For systems with a recycling process, a

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...
