Geological Features and C-H-O-S-Pb Isotopes at the Zhazixi Sb-W Deposit

Chemical Engineering Transactions, 2017
The Zhazixi Sb–W deposit in the Xuefeng arc metallogenic belt, South China, is one of the Sb deposits in Precambrian strata. The sources of the ore-forming fluid and the metallogenic material, as the bone of contention in geochemical field, are ...

Redox State of the Neoarchean Earth Environment [PDF]

, 2011
A Titan-like organic haze has been hypothesized for Earth's atmosphere prior to widespread surface oxygenation approx.2.45 billion years ago (Ga). We present a high-resolution record of quadruple sulfur isotopes, carbon isotopes, and Fe speciation from ...

Stable isotopes to study sulfur amino acid utilization in broilers

Animal, 2020
Nutritionists have been discussing whether the dietary supplementation of cyst(e)ine is required as a part of the dietary methionine (Met) in the total sulfur amino acid (TSAA) requirement to achieve optimum performance in broilers.

Exotic Nuclei and Matter in a Chirally Effective Approach

, 2015
A relativistic approach to describe nuclear and in general strongly interacting matter is introduced and discussed. Here, not only the nuclear forces but also the masses of the nucleons are generated through meson fields.

Fusion of radioactive $^{132}$Sn with $^{64}$Ni

, 2007
Evaporation residue and fission cross sections of radioactive $^{132}$Sn on $^{64}$Ni were measured near the Coulomb barrier. A large sub-barrier fusion enhancement was observed.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...
