The title com pound was prepared by the reaction of the elem ental com ponents in a tan ta ­ lum tube. EuA gG e (single crystal. X-ray, Imma, a = 467.0(1), b = 740.0(1), c = 798.1(1) pm, V = 0.2758(1) nm3, Z = 4, wR2 = 0.0371, 474 F2 values and 13 variables) crystallizes with the orthorhom bic structure of C eC u2. The europium atom s occupy the cerium positions, while the silver and germ anium...

The rare-earth borate Sc3B5O12 was synthesized under high-pressure / high-temperature conditions of 6 GPa and 1100 ◦C in a Walker-type multianvil apparatus. The single-crystal structure determination revealed an isotypy to RE3B5O12 (RE = Er–Lu). Sc3B5O12 crystallizes in the rare space group Pmna (Z = 4) with the parameters a = 1245.4(3), b = 443.46(9), c = 1222.1(2) pm, V = 0.675(1) nm3, R1 = 0...

Shape changes of Ag and Au nanoparticles supported on single crystal reconstructed SrTiO3(001) (111) substrates were investigated using scanning tunneling microscopy. Both metals nucleate as multiply twinned particles (MTPs) transform into face-centered-cubic crystals (SCs) beyond a critical volume. On SrTiO3(001)-c(4 × 2) the volumes are measured 141 ± 51 nm3 for 107 23 Au, whereas SrTiO3(111)...

Biological biogas upgrading with H2 derived from excess renewable electricity was modeled and simulated in PROII® (AVEVA Group plc, Cambridge, UK). An economic analysis performed for a plant processing 100,000 tons of biomass (substrate) per year. The biomethane production simulation results were validated laboratory experimental data, as well full-scale data obtained plants. A cost 0.47 €/Nm3 ...

The integration of mixed ionic electronic conducting (MIEC) membranes for air separation in a small-to-medium scale unit for H2 production (in the range of 650-850 Nm3/h) via auto-thermal reforming of methane has been investigated in the present study. Membranes based on mixed ionic electronic conducting oxides such as Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) give sufficiently high oxygen fluxes at temp...

Korea produced cattle manure has high energy potential due to its solids content, including sawdust. However, it is difficult use sawdust as a raw material for anaerobic digestion content of non-degradable organic materials. This study used hydrothermal carbonization, one the hydrolysis processes, analyze effect improving methane production efficiency through carbonization using livestock sludg...

Ultrabright fluorescent nanoparticles (NPs) hold great promise for demanding bioimaging applications. Recently, extremely bright molecular crystals of cationic fluorophores were obtained by hierarchical coassembly with cyanostar anion-receptor complexes. These small-molecule ionic isolation lattices (SMILES) ensure spatial and electronic to prohibit aggregation quenching dyes. We report a simpl...

Co-firing is the efforts to reduce use of fossil fuel (coal) form steam power plant. Adding biomass as a partial boiler coal consumption thereby reducing carbon dioxide emissions which can have an impact on greenhouse effect. This co-firing study implemented 5-20% palm kernel shells. The emission has decreased very significantly in by 20%, Carbon (CO2) from 7% 0.9% and monoxide (CO) 759 Mg/Nm3 ...

This work is devoted to the study of R2T2In1-xGax (R = La, Ce; T Ni, Cu) systems at 870 K, namely solubility fourth component in compounds with composition 2:2:1 and structural characteristics solid solutions. Samples for investigation were synthesized by arc-melting metals (purities better than 0.998) subsequent annealing K one month electric muffle furnace SNOL automatic temperature control. ...

Contaminants as particulate matter, sulfur, chlorine and tar should be removed from biosyngas to avoid damaging solid oxide fuel cells. However, there is no sufficient information on effect since they might potentially used a fuel, or cause performance losses irreversible damages. Therefore, this study aims assess whether can reformed inside the SOFC fuel. Short-duration experiments were conduc...
