Conversion of biomass into multi-products started several centuries ago. However, the idea to conceptualize portfolios of bioproducts and their associate interwoven processes as a biorefinery in reference to petroleum refinery dated only from few decades. ...
This manuscript covers two main topics. The first part dealt with the organocatalytic conjugate addition of Michael donors to phenyl vinyl selenone. The enantioselective Cinchona alkaloid-catalyzed Michael addition using a-substituted a-nitroacetates has b ...
In this paper, an analytical noise calculation is presented to derive the impact of process and design parameters on 1/f and thermal noise for a low-noise CMOS image sensor (CIS) readout chain. It is shown that dramatic noise reduction is obtained by using ...

While polymers are frequently used as membranes in industrial-scale sepns. due to their ease of synthesis and processing, their performance is limited by a well-documented permeability/selectivity tradeoff. A class of metal-org. frameworks known as zeoliti ...
Current study deals with the production of cellulases and xylanases from the Rhizopus oryzae SN5 isolated from composed soil of Himalayan pine forest, in order to meet the challenges of lignocellulosic biomass based biorefineries. Culture parameters for con ...
Transforming lignocellulosic biomass into fuels and chemicals has been intensely studied in recent years. A large amount of work has been dedicated to finding suitable solvent systems, which can improve the transformation of biomass into value-added chemic ...
A microstructured falling film reactor was applied to the dye-sensitized photochemical conversion of 1,5-dihydroxynaphthalene to juglone. This continuous-flow microreactor enables the efficient contacting of a gas and a liquid phase in combination with ext ...
Encapsulation of metal nanoclusters in porous solid polymer materials is a promising approach to combine the outstanding properties of both, heterogeneous and homogeneous catalysts. We report heterogeneous nano-engineered catalysts containing Pd-nanopartic ...
A novel Cinchona alkaloid-catalyzed enantioselective conjugate addition of alpha-alkyl substituted alpha-nitroacetates to phenyl vinyl selenone was developed. The resulting enantio-enriched alpha,alpha-dialkyl substituted alpha-nitroacetates were subsequen ...
This work is based on the assumption that it is possible to achieve sustainable development by preserving the twentieth century heritage. Modern European cinemas were especially vulnerable to the passing of time: in a few decades buildings with tremendous ...
