Glycerol, a non-biodegradable by-product during biodiesel production is a major concern to the emerging biodiesel industry. Many microbes in natural environments have the ability to utilize glycerol as a sole carbon and energy source. The focus of this study was to screen for microorganisms from soil, capable of glycerol utilization and its conversion to value added products such as ethanol and...

Electrospun filaments represent a new generation of medical textiles with promising applications in soft tissue repair. A potential strategy to improve their design is to combine them with bioactive molecules. Curcumin, a natural compound found in turmeric, is particularly attractive for its antioxidant, anti-inflammatory, and antimicrobial properties. However, investigating the range of releva...

[1] Significant variations in interannual and decadal recharge rates are likely in alluvial basins of the semiarid southwestern United States on the basis of decadal variations in climate and precipitation and correlation of El Niño with high rates of winter precipitation and streamflow. A better understanding of the magnitude of recharge variations in semiarid and arid regions would reduce wat...

The year 2015 was, at the time, the warmest since 1880, and many regions in the Northern Hemisphere (NH) registered record breaking annual temperatures. Simultaneously, a remarkable and widespread growing season greening was observed over most of the NH in the record from the Moderate Resolution Imaging Spectroradiometer (MODIS) normalized difference vegetation index (NDVI). While the response ...

We inferred climate drivers of 20th-century years with regionally synchronous forest fires in the U.S. northern Rockies. We derived annual fire extent from an existing fire atlas that includes 5038 fire polygons recorded from 12,070,086 ha, or 71% of the forested land in Idaho and Montana west of the Continental Divide. The 11 regional-fire years, those exceeding the 90th percentile in annual f...

Aim of study: Cava is Spain’s largest wine exporter. However, in the last 20 years, growth exports from protected designation origin (PDO) wineries has been lower than that other Spanish PDO wines, and Cava’s domestic market share fallen. From point view strategic management, it could be said seems are losing their competitive advantage. It therefore fundamental to perform an analysis maintain ...

In general, aqueous phase reforming (APR) is used to convert glycerol into 1,3-propanediol (1,3-PDO), nonetheless, studies have shown a low selectivity of 1,3-PDO. Therefore, this study aims optimize the 1,3-PDO by varying ultrasound (Us) irradiation process time between 10 and 50 ?min during catalyst preparation. This investigate effect on physiochemical properties activity catalyst. Ni–Mo/Al2...

Introduction Conclusions References

PdO, widely used in catalysis powder form for decades, has been predicted recently to be a Dirac semimetal. Synthesis of high-quality single crystals this material is thus great interest. Here, by using ozone-assisted molecular beam epitaxy, PdO thin films were grown on MgO (001) substrate. X-ray diffraction and transmission electron microscopy indicate the film $a/b$ axis oriented, with $c$ ly...
