Towards Bioleaching of a Vanadium Containing Magnetite for Metal Recovery

open access: yesFrontiers in Microbiology, 2021
Vanadium – a transition metal – is found in the ferrous-ferric mineral, magnetite. Vanadium has many industrial applications, such as in the production of high-strength low-alloy steels, and its increasing global industrial consumption requires new ...

De re metallica: the cosmic chemical evolution of galaxies [PDF]

open access: yesThe Astronomy and Astrophysics Review, 2018
The evolution of the content of heavy elements in galaxies, the relative chemical abundances, their spatial distribution, and how these scale with various galactic properties, provide unique information on the galactic evolutionary processes across the ...

The chemical evolution of oligonucleotide therapies of clinical utility

open access: yesNature Biotechnology, 2017
After nearly 40 years of development, oligonucleotide therapeutics are nearing meaningful clinical productivity. One of the key advantages of oligonucleotide drugs is that their delivery and potency are derived primarily from the chemical structure of ...

CHEMICAL EVOLUTION IN ALGOLS

open access: yesOdessa Astronomical Publications, 2012
We discuss the chemical abundance in Algol-type systems produced by different authors. Till this time most evolutionary changes in the chemical abundance of the components of Algols were studied by carbon depletion.

High-throughput library transgenesis in Caenorhabditis elegans via Transgenic Arrays Resulting in Diversity of Integrated Sequences (TARDIS)

open access: yeseLife, 2023
High-throughput transgenesis using synthetic DNA libraries is a powerful method for systematically exploring genetic function. Diverse synthesized libraries have been used for protein engineering, identification of protein–protein interactions ...

Refueling the Magic Furnace: Kilonova 2017 Rewrites the Story of Element Origins

open access: yesJournal of Big History, 2018
For more than half a century, we have understood element creation in the stars—described in Marcus Chown’s colorful image as “the magic furnace.” From 1958 until 2017, supernova explosions were thought to be the primary site of element creation above ...

Four terpene synthases contribute to the generation of chemotypes in tea tree (Melaleuca alternifolia)

open access: yesBMC Plant Biology, 2017
Background Terpene rich leaves are a characteristic of Myrtaceae. There is significant qualitative variation in the terpene profile of plants within a single species, which is observable as “chemotypes”.

Transcriptional and proteomic analysis of the innate immune response to microbial stimuli in a model invertebrate chordate

open access: yesFrontiers in Immunology, 2023
Inflammatory response triggered by innate immunity can act to protect against microorganisms that behave as pathogens, with the aim to restore the homeostatic state between host and beneficial microbes.

A review on fundamentals for designing oxygen evolution electrocatalysts.

open access: yesChemical Society Reviews, 2020
Electricity-driven water splitting can facilitate the storage of electrical energy in the form of hydrogen gas. As a half-reaction of electricity-driven water splitting, the oxygen evolution reaction (OER) is the major bottleneck due to the sluggish ...
