Element Neodymium (Nd), Group 19, Atomic Nuer 60, f-block, Mass 144.242. Sources, facts, uses, scarcity (SRI), podcasts, alchemical syols, videos and images. Neodymium was discovered in Vienna in 1885 by Karl Auer. Its story began with the discovery
Proteins are a substantial nitrogen source in soils provided that they can be hydrolyzed into bioavailable small peptides or amino acids. However, the strong associations between proteins and soil minerals restrict such proteolytic reactions. This study focused on how an extracellular fungal protease (Rhizopus sp.) hydrolyzed iron oxide-associated bovine serum albumin (BSA) and the factors
2019/9/7· Calcium (Ca) Strontium (Sr) Barium (Ba) Radium (Ra) If element 120 is produced, it will most likely be a new alkaline earth metal. Presently, radium is the only one of these elements that is radioactive with no stable isotopes. Element 120 would be radioactive

Cesium Cs 137 is a radioactive isotope of cesium with an atomic mass of 139 and potential appliion in radiotherapy. Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and plutonium..
But we can just see as nature using human’s assistance to add calcium and minerals from the sea to the land in piles, because corals and clams can’t cli up shore! Most Japanese think too, that shell mounds are mere garbage deposits, since the conventional understandings of ancient Jomon natives are that they were primitive stupid people.
2017/9/10· Hydrochloric acid on limestone: This video demonstrates what happens when one drop of dilute (10%) hydrochloric acid is placed on a piece of limestone. Protective glasses and gloves are recommended when doing the acid test. Magnesite: The mineral magnesite, which has a chemical composition of MgCO 3, will effervesce weakly with warm hydrochloric acid and very weakly with cold …
A liquid metal battery is a new type of molten salt battery designed for grid storage appliions. First proposed by Donald Sadoway, a Massachusetts Institute of Technology (MIT) materials professor, in 2009, the liquid metal battery consisted of a current collecting container filled a molten antimony hode at the bottom, a salt electrolyte for the middle layer, and liquid magnesium metal
The marine dissolved organic carbon (DOC) pool is an important player in the functioning of marine ecosystems. DOC is at the interface between the chemical and the biological worlds, it fuels marine food webs, and is a major component of the Earth’s carbon system. Here, we review the research showing impacts of global change stressors on the DOC cycling, specifically: ocean warming and
