The purpose of this study was to determine the reducing power, metal chelating, and radical scavenging capabilities of water and ethanol extracts of sumac (Rhus coriaria L.), comparatively. The water and ethanol extracts of sumac were evaluated for their radical scavenging activities by means of the DPPH and DMPD assays. Water extract of sumac (R. coriaria L.) scavenged radicals effectively with EC50 values of 36.4μg/ml for DPPH free radical and 44.7μg/ml for DMPD cation radical. Similarly, the total reducing power of water extract was found higher than ethanol extract in both potassium ferricyanide reduction (FRAP) and cupric ions reduction capacity methods (CUPRAC). 2,2'-Bipyridine was used to determine the metal chelating activity and the result of water extract was found higher than ethanol extract. Total phenolic and total flavonoid contents of both extracts were studied as well. The values of water extract were found to be higher than that of ethanol extract. The present study found that water extracts of sumac (R. coriaria L.) have effective antioxidant and radical scavenging activities as compared to ethanol extracts. © 2010 Elsevier Ltd. Source

A novel kaolinite-nicotinamide composite was prepared utilizing a kaolinite/N-methylformamide intercalation compound as a precursor material and examined the structural properties of the intercalated species. The X-ray powder diffraction pattern illustrated that intercalation of nicotinamide molecules between the layers of kaolinite caused an emergence of new peaks at 6.87 and 13.63(2θ) with the distance of 12.86 and 6.49 Å, respectively, belonging to the d001 and d002 planes of kaolinite-nicotinamide. The expansion of the d001 basal spacing (5.68 Å) point out the existence of nicotinamide species in the layers of kaolinite which are located as a monolayer arrangement. The aromatic rings of the nicotinamide molecules are perpendicular to the aluminum layers of kaolinite and also both top hydrogen atom of pyridine ring and oxygen atom of carbonyl is keyed into the ditrigonal holes in the silicate layers. The appearance of the peaks at 3630, 3533, 1596 and 1441 cm-1 and decrease of intensity of the inner-surface hydroxyls peak at 3696 cm-1 prove that nicotinamide molecules intercalated into kaolinite layers through forming H-bonds via pyridine ring nitrogen with inner-surface hydroxyls of kaolinite. The thermal stability of intercalated NAM molecules is up to 238°C. The organic molecules located in the interlayer spacing led to an appreciable decrease of particle size and differences in the morphology. The specific and mesoporous surface areas of intercalated composites increased whereas the average pore width of these species decreased with respect to that of pure kaolinite. © 2012 Elsevier B.V.

A Trombe wall that uses a phase change material (PCM) as the heat storage medium is usually called a PCM Trombe wall or PCM wall. A research project was conducted to investigate the performance of coupled novel triple glass (NTG) and PCM wall, which is simply called PCM wall in this paper, as a solar space heater. The south façade of a test room was constructed using PCM walls. Rubitherm® GR35 and GR41 were incorporated into the plaster of the walls as PCM. The ratio of the solar energy gain provided by the PCM walls to the heat load of the test room per month varied from 4% to 70%; daily overall efficiency of the PCM walls varied from 20% to 36%; and solar transmittance of the NTG varied from 0.45 to 0.55 during the heating period. The overall efficiency of the PCM wall including GR35 was higher than that of the PCM wall including GR41. © 2012 Elsevier Ltd. Source

In this study; an experiment was carried out to examine the effects of LPG-ethanol fuel blends on the emission performance of a four cylinder SI engine. Such a type of research could not be reached in the literature. The modifications to the engine were minimal and a dual throat carburetor was used to mix LPG and ethanol before being fed into the carburetor. Using engine cooling water temperature, ethanol was evaporated before entering the carburetor. Performance tests were conducted to determine the correct air/fuel ratio (lambda = 1). Exhaust emissions were analyzed for CO, CO 2, NO x, HC, O 2 using LPG-ethanol blends with different percentages of fuel blends at variable engine speeds ranging between 1000 and 5000 rpm. It was observed that depending on the rate of ethanol increase in mixture, the CO 2, CO, NO x and HC emission concentrations in the engine exhaust gases decreased. © Sila Science. Source
