A NiMgGa-layered double hydroxide (NMG-LDH) is synthesized as an efficient catalyst precursor for dry reforming of methane (DRM). NMG-LDH converted to intermetallic Ni3Ga/MgO upon reduction. Compared a monometallic Ni/MgO prepared from NiMg-LDH, the exhibits high CH4 (∼48%) and CO2 (∼52%) conversions well excellent stability against coking during DRM. The reversible phase transition between Ni3...

This study was aimed to evaluate the correlation between in vitro fermentation and in situ degradation parameters and to predict dry matter degradability and energy protein synchronization of roughage based diets. Different inclusion of roughage in diets [roughage 50% diet (R50D), roughage 60% diet (R60D), roughage 65% diet (R65D) and roughage ...

This paper investigates the origins of sub-threshold slope degradation in vertical MOSFETs (v-MOSFETs) due to dry etching of the polysilicon surround gate. Control v-MOSFETs exhibit a degradation of subthreshold slope as the channel length is reduced from 250 to 100 nm, with 100 nm transistors having a value of 125 mV/dec and a DIBL of 210 mV/V. The effect of the polysilicon gate etch is invest...

Low-loss waveguides constitute an important building block for integrated photonic systems. In this work, we investigated low-loss photonic device fabrication in Ge23Sb7S70 chalcogenide glass using electron beam lithography followed by plasma dry etching. High-index-contrast waveguides with a low propagation loss of 0.5 dB/cm and microdisk resonators with an int...

The Pantanal is a large savanna wetland (138,183 km2 in Brazil), important for its wildlife, fed by tributaries of the upper Paraguay River, center of South America (Brazil, touching Bolivia and Paraguay). Uplands are plateaus (250-1,200 m high, 215,000 km2 in Brazil) and flatland is the Pantanal (80-150 m high, 147,574 km2 in Brazil). Rivers are slow moving when they meet the flatland (slope 0...

Industrial-scale reforming of methane is typically carried out with an excess oxidant to suppress coking the catalyst. On other hand, many academic studies on dry employ a CO2/CH4 ratio unity quickly observe which can be reduced by adding catalyst promoter. In this work, Ni/Al2O3 catalysts were tested for (CO2/CH4=1) additional regeneration steps test resistance against oxidation treatment. The...

A pure Silicate host namely Sr2MgSi2O7 as a support for a long-lasting afterglow when dopped with rare-earth elements was sought after. To this end the process of obtaining firing temperatures of the above mentioned phase in normal condition was carried out using suggested wet and dry methods. The degree of purity obtained in these preparatory methods as wel...
