a novel mixing approach for achieving a good dispersion of multi-walled carbon nanotubes (mwcnts) in ethylene- propylene diene monomer (epdm) matrix has been investigated. in this approach epdm was modified with vinyltrimethoxysilane (vtms) during melt mixing. in addition the effect of mwcnt concentration on mechanical and rheological properties of modified epdm has been studied. the formulated...

Chemical Modification of Oligonucleotides: A Novel Approach Towards Gene Targe...

Microbial biotransformation, one of the tools of green chemistry, is widely used in organic synthesis to cutshort number of organic intermediates in obtaining the final required compounds. In the present study, an approach was made for preparing substituted derivatives of coumarin as therapeutic agents. Nine biotransformation experiments were performed where random combination of four microorga...

Polymer-supported O(6)-(benzotriazol-1-yl)inosine derivatives (Pol-I and Pol-dI) have been synthesized reasonably effectively via reaction of nucleoside phosphonium salts with polymer-linked HOBt (Pol-HOBt). In constast to solution chemistry, use of polymer-supported BOP (Pol-BOP) did not lead to efficient nucleoside loading. Presence of the nucleosides on the support could be readily detected ...

in this study, removal of methylene blue (mb) and maxilon blue sl 200% (mb sl) dyes from aqueous solutions by using raw clay (rc) of nevsehir (turkey) vicinity and ultrasonic-acid modified clay (mc) was investigated. adsorption was carried out with 500 mg/l mb and 50 mg/l for mb sl in terms of different adsorbent dosages, contact time, solution ph, temperature and stirring speed. the fitting of...

This paper presents a novel Kalman-filter-based approach for approximately enforcing a linear constraint in adaptive control. One application is that this leads to alternative forms for well-known modification terms such as e modification. It is shown that employing this approach does not increase the theoretical guaranteed ultimate bounds for the closed-loop error signals of an existing adapti...
