Delft University of Technology ft]), also known as TU Delft, is the largest and oldest Dutch public technical university, located in Delft, Netherlands. With eight faculties and numerous research institutes it hosts over 19,000 students , more than 3,300 scientists and more than 2,200 people in the support and management staff.The university was established on January 8, 1842 by King William II of the Netherlands as a Royal Academy, with the main purpose of training civil servants for the Dutch East Indies. The school rapidly expanded its research and education curriculum, becoming first a Polytechnic School in 1864, Institute of Technology in 1905, gaining full university rights, and finally changing its name to Delft University of Technology in 1986.Dutch Nobel laureates Jacobus Henricus van 't Hoff, Heike Kamerlingh Onnes, and Simon van der Meer have been associated with TU Delft. TU Delft is a member of several university federations including the IDEA League, CESAER, UNITECH, and 3TU. Wikipedia.

A method of maneuvering a smaller ship which is located alongside a larger ship whereas both ships initially have the same course and the same speed. The smaller ship includes a bow rudder or a Magnus rotor at a bow thereof and is maneuvered away from the larger ship by means of changing the orientation of its bow rudder or activating its Magnus rotor, respectively.

A quadrature LC tank based digitally controlled ring oscillator (DCO). The oscillator structure incorporates a plurality of stages, each stage including a buffer and a series LC tank. Four stages are coupled together to create a 360 degree phase shift around a loop. The oscillation frequency of the oscillator is the same as the resonant frequency of each LC tank, therefore it avoids quality factor degradation of LC tanks found in the prior art. In one example embodiment, class-D amplifiers are used to drive each of the LC tanks. Capacitor banks before at the input and output of the buffers provide coarse and fine tuning of the frequency of oscillation. The high efficiency exhibited by these amplifiers results in very good phase noise performance of this oscillator. The oscillator utilizes a startup circuit to launch oscillation upon power on.

Transformation of biomass into commodity chemicals using enzymes or cells will be successful if the production process is more attractive than for alternative options to produce these chemicals. Sufficient second generation biomass should be available for a reasonable price, the price will not only be dictated by the biomass production but also by competitive uses of this biomass such as combustion for energy generation. All biomass components should be convertible into product, or otherwise into valuable coproduct. Too high bioreactor investments, due to high O2 requirements or too low productivities, should be avoided. Biochemical processes compete with chemical processes that aim at similar routes from biomass to product. The biochemical process should be more selective or should avoid production and isolation of intermediate chemicals. Scientific discoveries and method development have been very important to increase the rate of development of biochemical routes.

In this tutorial review, the fundamental concepts underlying the principles of green and sustainable chemistry - atom and step economy and the E factor - are presented, within the general context of efficiency in organic synthesis. The importance of waste minimisation through the widespread application of catalysis in all its forms - homogeneous, heterogeneous, organocatalysis and biocatalysis - is discussed. These general principles are illustrated with simple practical examples, such as alcohol oxidation and carbonylation and the asymmetric reduction of ketones. The latter reaction is exemplified by a three enzyme process for the production of a key intermediate in the synthesis of the cholesterol lowering agent, atorvastatin. The immobilisation of enzymes as cross-linked enzyme aggregates (CLEAs) as a means of optimizing operational performance is presented. The use of immobilised enzymes in catalytic cascade processes is illustrated with a trienzymatic process for the conversion of benzaldehyde to (S)-mandelic acid using a combi-CLEA containing three enzymes. Finally, the transition from fossil-based chemicals manufacture to a more sustainable biomass-based production is discussed. © 2012 The Royal Society of Chemistry.
