Selenium and silica are minerals naturally found in the soil and absorbed in all living things, including human beings, through the diet. They are also used in manufacturing items such as computers, glass, paper, paints, foods and medicines. Your body receives selenium and silica from the plant and meat products you eat.
ACS Agricultural Science & Technology 2021, 1, 5, 443-448 (Article) Publication Date (Web): June 22, 2021. Abstract. Full text. PDF. ABSTRACT. Brachiaria brizantha is the most common forage plant used in cattle pastures.
In vitro antibactericidal tests indicated that the Se/MSNs could exhibit better antibacterial activity against S. aureus than pure Se nanoparticles after 6 and 24 h of culturing. In this work, different concentrations of Se-incorporated mesoporous silica nanospheres (MSNs) (5Se/MSNs and 10Se/MSNs) were successfully synthesized via an in-situ one-pot method.

A process comprising treating silica with at least one of selenium or tellurium under nonoxidizing conditions at a temperature of at least 370° C. and a subsequent second step wherein the thus-treated silica is contacted with an oxidizing ambient at a temperature within the range of 370°-900° C. The silica can contain a chromium compound in which case the resulting product is …

INNOVATIONS Nanovesicles are smart, food-grade nanocarriers engineered to tune the performance of the functional ingredients, both before consumption (i.e., production and shelf-life) and after consumption (i.e., in the digestive tract). Nulixir's smart nanocarriers can easily incorporate any functional ingredient (e.g., hydrophobic or hydrophilic) into food and beverage …
Sputtering: Process, Types, and Uses. Sputtering is a physical process in which atoms in a solid-state (target) are released and pass into the gas phase by bombardment with energetic ions (mainly noble gas ions). Sputtering is usually understood as the sputter deposition, a high vacuum-based coating technique belonging to the group of PVD ...

This study aims to investigate the selenium (Se) distribution in the soils of the vast cultivated areas of Aksu Prefecture in mid-Western Xinjiang of Northwest China. The study of the origin and enrichment mechanism of Se in the soils of alluvial fans of these areas (also known as oasis areas) are of great importance for the conservation and development of Se-rich resources.

Silica, as an anti aging agent, helps to retain moisture under the skin and maintain youthful skin tone devoid of wrinkles. It also helps to promote healthy hair, skin and nails. 4. …
The uniform selenium distribution sections, usually lie in the peripheral farming land and Xiyu Group loess highland, do not reveal a clear tendency of elemental vertical variation. These sections are far from the core farming land, suggesting that Se vertical migration would not occur in the absence of agricultural activities.
Flooding induces low oxygen (hypoxia) stress to plants, and this scenario is mounting due to hurricanes followed by heavy rains, especially in subtropical regions. Hypoxia stress results in the reduction of green pigments, gas exchange (stomatal conductance and internal CO2 concentration), and photosynthetic activity in the plant leaves.
Silica (SiO 2) in the form of sharp flints were among the first tools made by humans. The ancient civilizations used other forms of silica such as rock crystal, and knew how to turn sand into glass. Considering silicon's abundance, it is somewhat surprising that it …

Circu+Plus for Laminitis In October of 2016, my mare Chexy came up lame. Her feet were sore and she could barely walk. There were no signs at all on the days or weeks prior, so I called the vet who confirmed that she was in the early stages of laminitis. I tried her on Bute for only 3 days along with some ulcer paste, as she doesn't do well on non-steroidal anti-inflammatories.
During smelting of copper sulfide concentrate, selenium is distributed between silica-saturated iron-silicate slag and copper-iron sulfide matte. The recovery coefficients of selenium between slag and matte were determined as a function of the initial concentration of selenium at 1523 K (1250 °C) under an inert atmosphere in a vertical tubular furnace.
