Glasses along the composition line 0.5Al2O3–xSiO2 (1 ≤ x ≤ 6) were prepared via a novel sol-gel route using tetraethylorthosilicate and aluminum lactate as precursors. The structural evolution from solution to gel to glass ...

Al is a ubiquitous element on the earth crust and is considered a non-essential element for humans since it is not involved in any biochemical process. Aluminum may act as a toxic species when it is introduced directly ...

Sepsis is the disease that kills the most worldwide and affects millions of people every year, it also has high mortality rates that are associated with delayed diagnosis due to the centralization and complexity of laboratory ...

Refractory materials are used as linings in most equipment of heavy industries. As the latter are continuously seeking to reduce expenses in order to increase their energy efficiency and productivity, the evaluation of ...

The medium-range order of 0.5Al2O3-xSiO2 glasses (1 ≤ x ≤ 6) prepared via a new sol-gel route from the Al lactate precursor has been studied by 29Si and 27Al single- and double-resonance solid-state NMR techniques. For ...

The drying step of hydraulic-bonded refractory castables is usually carried using conservative and long heating schedules, in order to preserve the microstructure of dense ceramic linings and inhibit explosive spalling ...

Twenty-eight Holstein cows (4 with ruminal cannulas) were blocked by days in milk into 7 groups and then randomly assigned to 1 of 7 balanced 4 4 Latin square diet sequences. The diets contained [dry matter (DM) basis] ...
