Memory Of Chirality

<p>Many chiral compounds have become of great interest to the pharmaceutical industry as they possess various biological activities. Concurrently, the concept of “memory of chirality” has been proven as a powerful tool in asymmetric synthesis, while flow chemistry has begun its rise as a new enabling technology to add to the ever increasing arsenal of techniques available to the modern day chemist. Here, we have employed a new simple electrochemical microreactor design to oxidise an L-proline derivative at room temperature in continuous flow. Flow performed in microreactors offers up a number of benefits allowing reactions to be performed in a more convenient and safer manner, and even allow electrochemical reactions to take place without a supporting electrolyte due to a very short interelectrode distance. By the comparison of electrochemical oxidations in batch and flow we have found that continuous flow is able to outperform its batch counterpart, producing a good yield (71%) and a better enantiomeric excess (64%) than batch with a 98% conversion. We have, therefore, provided evidence that continuous flow chemistry has the potential to act as a new enabling technology to replace some aspects of conventional batch processes. </p>

Electrical Characterizations

This work presents a nanodamascene process for a CMOS back-end-of-line fabrication of metallic single electron transistor(SET), together with the use of simulation tools for the development of a SET SRAM memory cell. We show room temperature electrical characterizations of SETs fabricated on CMOS with relaxed dimensions, and simulations of a SET SRAM memory cell. Using their physical characteristics achievable through the use of atomic layer deposition, it will be demonstrated that it has the potential to operate at temperature up to 398 K, and that power consumption is less than that of equivalent circuit in advanced CMOS technologies. In order to take advantage of both low power SETs and high CMOS drive efficiency, a hybrid 3D SET CMOS circuit is proposed.

Major Progress

TSV is one of the key technologies for 3D integration . TSVs co-integrated with passives including high density capacitors enable highly integrated heterogeneous solutions required because of the smaller size of the electronic modules . Even if there is still a lot to do , significant progress has already been done on the process , on the testability , on the performances of these smart interposers .The major progress is in the adoption of the technology .In this paper we'll expose some examples where the adoption was driven by cost, performances & miniaturization. Emphasis will be placed on the performances of the new generation of 3D Silicon capacitors, using key enabling technology like ALD and amazing architecture that allow impressive capacitance density increase.

Here, we have employed a new simple electrochemical microreactor design to oxidise an L-proline derivative at room temperature in continuous flow. Electrochemical methods are inherently green and environmentally benign. However, organic electrosynthesis via microflow reactor has number of advantages such as fast reaction’s time, optimization and scale up, safer environment, high selectivities and reduce chances of overoxidation. Flow electrochemical reactor provides high surface-to-volume ratio and reactions are possible to perform in the reactor without a supporting electrolyte due to a very short interelectrode distance. By the comparison of Hofer Moest type electrochemical oxidations at room temperature in batch and flow, we have achieved that continuous flow electrolysis is better than batch electrolysis, producing a good yield (71%) and a better enantiomeric excess (64%).
