Thermal degradation of antibiotics has been studied for decades in a broad range of disciplines including food production, agriculture and analytical chemistry. Yet, there is a lack of thermal stability data for many antibiotics. Here we systematically investigated the thermal stability of ten commonly prescribed antibiotics applying a laborsaving automated inhouse pressurized dynamic flow-thro...
Thermal pastes play an important role in transmitting heat generated by an integrated circuit chip from its back side to a cooling cap or heat sink which transfers the heat to the environment. Most thermal pastes are formulations of solid, thermally conducting particles in a liquid matrix loaded to very high solids content. The mixing process for such pastes is complex but important, since it d...
This work aimed to evaluate the thermal and photo stability of the antioxidant potential (AP) of the Spirulina platensis biomass. Thermal stability was established at 25ºC, 40ºC and 50ºC for 60 days, in the dark, protected from light. Photo stability was evaluated using UV (15 W, λ = 265 nm) and fluorescent (20 W, 0.16 A, power factor FP > 0.5, 50/60 Hz, 60 lm/w, 1200 lm) light for 90 days in c...
