Loading selenium (Se) into microporous carbon spheres (MPCS) for the use as a cathode material is an efficient method for reducing the volume expansion and dissolution of polyselenides in the lithium-selenium (Li–Se) batteries during cycling. In this study, we produced MPCSs from glucose using a simple and efficient hydrothermal synthesis ...
Which is Better – Selenide or Selenium? In this era, many people use the Selenide tool over the Selenium Web Driver tool because Selenide is specially developed for test automation using Selenium WebDriver. And, the other reason to use Selenide over Selenium is that it comes with good APIs that you can connect with Selenium WebDriver.
This is a systematic review of existing data on dietary selenium (Se) intake and status for various population groups in Europe (including the United Kingdom (UK)) and the Middle East.

Results indicated that Se was strongly retained by the processes such as precipitation reaction with ferrous ions in bentonite. Se K-edge X-ray absorption near-edge structure (XANES) measurements were performed at the BL-11 beamline at SAGA Light Source, and the results revealed that the oxidation state of Se in the bentonite remained Se(IV).

Urmatoarele alimente sunt considerate surse bune de seleniu: 1. Alunele braziliene. 2. Semintele de floarea soarelui. 3. Pestele (ton, halibut, sardine, cambula, somon)
A standard dose is around one teaspoon of powdered clay daily. The easiest way to consume the clay is to mix it with water. It is usually easiest to do this in a container with a lid so that you can shake the contents together. Bentonite clay is frequently used with Psyllium or other fiber supplements in a colon cleanse.

In primul si cel mai important rand, seleniul contribuie la reglarea unor enzime care controleaza activitatea hormonala din organism. Foarte important de stiut este ca in tiroida se gaseste cel mai mult seleniu. Acest mineral regleaza secretia de hormoni T3 si T4, hormoni responsabili cu buna functionare a metabolismului.
Bentonite clay normally comes as a clay powder you can mix with water. It's easy to make a paste and use it as a skin-soothing ointment, face and hair mask, or armpit detox. Plus, you can add it to your bath water or brush your teeth with the powder. Ready-to-use skincare products with the clay are also available.

The sorption behaviour of uranium(VI) and selenium(IV) on a purified bentonite sample has been investigated and the results compared with those for sorption onto the unpurified material and goethite. Batch sorption data for U(VI) on purified bentonite show strong sorption in the pH range 5 to 8 ( R d >10 4 cm 3 g −1 ).

10%Se is redox-sensitive, and its oxidation state varies from -2 to 6 depending on the redox conditions and pH of the solution. Large quantities of ferrous ions formed in bentonite due to corrosion of carbon steel overpack after the closure of a repository are expected to maintain a reducing environment near the repository.
