The most important factor affecting the microwave proper-ties of a snowcover is the liquid water content (snow wetness). An FM-CW(26.5-40 GHz) radar has been used to investigate the influence of snowwetness on the magnitude of radar backscatter from a snowcover. Theradar backscatter measurements from a wet snowcover on a windy daysuggest that evaporative cooling due to the w...

The effect of different active phases Fe/SiO2 catalyst on the physio-chemical properties and catalytic performance in CO2 hydrogenation under mild conditions (at 220 °C an ambient pressure) was comprehensively studied this work. prepared by incipient wetness impregnation method. Hematite (Fe2O3) calcined activated hydrogen, carbon monoxide, hydrogen followed to form a metallic iron (Fe/SiO2-h),...

Fischer-Tropsch catalyst preparation parameters, such as cobalt precursor and impregnation solvent, determine structure in fine catalytic performances of Co-based catalysts. Co particles 3–7 nm mean size were prepared by incipient wetness on surface-oxidized CNT. In this work, the crucial impact chemistry operating between support during properties is demonstrated, influence CNT surface charact...

The development of efficient strategies to recycle lithium-ion battery (LIB) electrode materials is an important yet challenging goal for the sustainable management waste. This work reports a facile and economically method convert spent cathode material, LiFePO4, into high-performance NiFe oxy/hydroxide catalyst oxygen evolution reaction (OER). Herein, Ni-LiFePO4 synthesized via wetness impregn...

Vacuum Impregnation in food industry is an interesting process particularly in semy-dry fruit processing. At the beginning of the process the pressure is reduced and the internal gas in the product pores is expanded and partially flows out, after that, when atmospheric pressure is restored and residual gas is compressed, the external liquid flows into the pores. Although vacuum impregnation pro...

The objective of this work was to develop and to evaluate adaptive neuro-fuzzy inference systems as methodology to describe the severity of soybean rust (Phakopsora pachyrhizi) monocyclic process in soybean [Glycine max (L.) Merr.], under effects of leaf wetness, temperature, and days after fungi inoculation. The experiment was conducted in growth chambers with mean air temperatures of 15, 20, ...

Recent advances in physically-based simulations have made it possible to generate realistic animations. However, in the case of solid-fluid coupling, wetting effects have rarely been noticed despite their visual importance especially in interactions between fluids and granular materials. This paper presents a simple particle-based method to model the physical mechanism of wetness propagating th...

Novel yttrium-doped CeO2, MnOx, and CeMnOx composites are investigated as catalysts for low-temperature NH3-SCR. The study involves the preparation of unmodified oxide supports using a citrate method followed by modification with Y (2 wt.%) two approaches, including one-pot incipient wetness impregnation undoped oxides. NH3-SCR reaction is studied in fixed-bed quartz reactor to test ability pre...

Co/TiO2–MgAl2O4 was investigated in a fixed bed reactor for the dry reforming of methane (DRM) process. prepared by modified co-precipitation, followed hydrothermal method. The active metal Co loaded via wetness impregnation catalyst characterized XRD, SEM, TGA, and FTIR. performance DRM process with temperature 750 °C, feed ratio (CO2/CH4) 1, loading 0.5 g, flow rate 20 mL min?1. effect suppor...
