Hace 2 días · List of radioactive nuclides by half-life. This is a list of radioactive nuclides (sometimes also called isotopes ), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds. [1]
Hace 9 horas · I believe that even three decades after the Chernobyl disaster, the situation hasn't changed enough to allow for safe living and agricultural activities in these territories. Yes, the radiation levels of cesium-137 and strontium-90, which have a half-life of about 30 years, have indeed decreased.
Hace 1 día · Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that, even if it had been running since the dawn of time around 13.8 billion years ago, the clock still wouldn't have lost or gained a full second.
Hace 5 días · Moreover, the biological functions of ZnCu remain to be corroborated. Herein, the teriparatide (PTH)-mediated strontium–zinc phosphate (SrZnP) organic–inorganic hybrid coating was fabricated on the surface of ZnCu substrate via a chemical conversion method to contain the release of Zn ions and improve biofunctionality in osteogenesis.
Hace 5 días · ConspectusThe manipulation of functional oxide materials’ properties through energy-efficient means is of great importance in materials science. Electric field-driven ionic control of functional oxides presents a versatile and effective approach for tailoring material properties, including insulator–metal transitions, superconductivity, magnetism, and optical characteristics, through spin ...
I am starting to take Pure Encapsulations Strontium Citrate supplement as well as a combined Vitamin D3/ Vitamin K2 tablet, and Red Mineral Algae ( calcium). However, I have read that K2 is a blood clotting agent and Strontium Citrate can cause blood clots. Is there anyone who can give me more information about this?
Came with documents, supposedly been in storage since 1979, never used. Still has the strontium-90 check source in the probe, no idea how hot it is since I don't have a decekt beta-detector. I have not been able to get it to work tho. Made some AA adapters and also tried cells from a 4.5V 3r12 battery.
