Higher reactivity
Did you know?
Reactivity is a somewhat vague concept in chemistry. It appears to embody both thermodynamic factors and kinetic factors—i.e., whether or not a substance reacts, and how fast it reacts. Both factors are actually distinct, and both commonly depend on temperature. For example, it is commonly asserted that the reactivity of group one metals (Na, K, etc.) increases down the group in the periodic table, or that hydrogen's reactivity is evidenced by its reaction with oxygen. In fac… WebHigh-reactivity metakaolin (HRM) is a highly processed reactive aluminosilicate pozzolan, a finely-divided material that reacts with slaked lime at ordinary temperature and in the presence of moisture to form a strong slow-hardening cement. It is formed by calcining purified kaolinite, generally between 650–700 °C in an externally fired ...

Web12 de dez. de 2024 · Platelet reactivity was measured using the PFA-100 platelet analyser, multiple electrode aggregometry, and was expressed as a novel platelet reactivity score (PRS). Patients were divided using their PRS scores into high platelet relativity or low platelet reactivity subgroups (HPR or LPR).

WebPlatelet reactivity reflected by P-selectin expression as markers of platelet degranulation was determined by flow cytometry. 13 Platelet reactivity was measured in unstimulated samples and after ex vivo platelet stimulation by ADP (low dose: 7.8 µM and high dose: 31.2 µM; Sigma-Aldrich, St Louis, MO, USA).
A substance reacts when the products formed from a chemical reaction have lower energy (higher stability) than the reactants. The energy difference can be predicted using valence bond theory, atomic orbital theory, and molecular orbital theory. Basically, it boils down to the stability of electrons in their orbitals. … Ver mais The organization of elements on the periodic table allows for predictions concerning reactivity.
