Evaluation of adhesion forces of calcium carbonate scalle formation on stainless steel AISI 304 through tribological tests

Abstract: This study aims to evaluate the adhesive forces of calcium carbonate encrusted on the metallic surface of AISI 304 stainless steel through linear scratch tribological tests. The formation of mineral scale on metallic surfaces is a relevant phenomenon in several industrial sectors, such as the oil industry, heat exchanger Leia mais…

Predicitng calcium carbonate scaling in tubular reaztors: a thermodynamic and kinetic model with experimental data validation

Abstract: This paper presents a thermodynamic and kinetic model for simulating calcium carbonate scaling in a tubularreactor under varying saline composition, temperature, and flow rate. Simulation results are compared withexperimental data obtained from a tubular reactor developed by the IPT and Petrobras. A mathematicalmodel based on thermodynamics and crystallization kinetics Leia mais…

Synthesis and characterization of chrominum-free black pigment from the SrO-Fe2O3-Mn2-O3 system via combustion method

Abstract: Chromium-free black pigments are promising candidates for use in enamels for ceramic glazes and for heat-absorbing applications, such as the black bands on automotive windshields and rear windows. In this work, a black pigment from the SrO–Fe₂O₃–Mn₂O₃ system was synthesized by combustion reaction. The powders were heat-treated at 600 Leia mais…

rBCG-LTAK63 enchances protection aginst tuberculosis by inducing autophagy and circadian gene regulation

Abstract: Tuberculosis (TB) remains a global public health challenge, with the current BCG vaccine providing limited efficacy in adults, and available treatments being lengthy and debilitating. To overcome these challenges, we have previously developed a recombinant BCG strain expressing the detoxified E. coli Heat-Labile Toxin (LTAK63), providing increased protection in Leia mais…
