HIDROGEOLOGIA DO ESTADO DO RIO DE JANEIRO

Revista Águas Subterrâneas, 2006
O Estado do Rio de Janeiro é constituído predominantemente por rochas cristalinas. Por este motivo, as águas subterrâneas estão espacialmente mais distribuídas em aqüíferos fissurais, uma vez que os aqüíferos porosos estão nas planícies litorâneas e ...

Fe–Mn Heterojunction Modulated Electronic Environment for Enhanced CO2 Capture and In Situ Conversion

Carbon Energy, EarlyView.
Fe–Mn heterojunctions in CaO‐based dual‐functional materials create a built‐in electric field that drives electron transfer. This process generates oxygen vacancies and facilitates CO2 activation, achieving superior conversion. Waste‐derived Fe/Ca oxides enable low‐cost, thermally stable materials, offering a strategy for sustainable carbon capture and

Impact of A‐Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL‐DRM)

Chemistry – A European Journal, EarlyView.
Sr doping regulates oxygen exchange and methane activation in LaFeO3, suppressing nonselective CH4 cracking and coke formation during CL‐DRM. La0.7Sr0.3FeO3 provides the optimal balance, delivering ∼40% CH4 conversion, an H2/CO ratio of 2, and >95% carbon balance.

DRM, Complexity, and Correctness

IEEE Security and Privacy Magazine, 2007
Steve Bellovin looks at the complex code behind Microsoft Vista and its DRM mechanisms. Increased amounts of code add to insecurity, but the real danger with DRM is with increased interaction among different pieces of code. A lot of new mechanisms have been introduced; more seriously, a lot of new communications paths and dependencies have been ...

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

Serial 1H-NMR Spectroscopy Study of Metabolic Impairment in Primates Chronically Treated with the Succinate Dehydrogenase Inhibitor 3-Nitropropionic Acid

Neurobiology of Disease, 1999
Previous studies in primates have shown that chronic systemic administration of the succinate dehydrogenase (SDH) inhibitor, 3-nitropropionic acid (3NP), replicates most of the motor, cognitive, and histopathological features of Huntington's disease.

Random forest regression for catalyst performance prediction and validation of tri‐reforming of methane (TRM)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Carbon dioxide‐reduced hydrogen can be synthesized through various methods such as dry‐reforming (DRM), steam reforming (SMR), and partial oxidation (POX). Tri‐reforming of methane (TRM) is a promising technology which combines all the above‐mentioned processes for the simultaneous production of hydrogen and syngas with high energy efficiency.

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...
