Abstract

Application of the nanofiltration (NF) and ultrafiltration (UF) processes is applied in the handling of water that is produced raw. The application has been investigated in the current day through various studies (Wang 14). The experiment of the processes of both nanofiltration and ultrafiltration is conducted in the laboratory unit which is operated in a pattern of cross flow (Ashaghi, Ebrahimi, & Czermak, 46). The study that was conducted in Oilfield of North Sea using the process of membranes of ultrafiltration (UF) and microfiltration (MF) indicated that the content of hydrocarbon decreased from 50 mg/l to 2 mg/l which recorded ...

This document is a project proposal for the development of starch-based hemostatic products. Acknowledgement. Much thanks to the project supervisor who offered guidance in every step of the development of this proposal. Developing starch based hemostatic products Project summary. Purpose: This proposal is envisioned to develop a hemostatic agent from purified plant starch. In this case, the product of the reaction should be developed by the formation of microporous hemosphere particles after etherification, esterification and crosslinking of glucose molecules to form ethyl propanetriol (glycerol-ether links (1-3 deoxy propanol)). The second intention of this study is to investigate the properties ...

Introduction

The Anti-Markovnikov process in organic chemistry generally involves addition reaction method of an electrophilic substituent, HX to an alkene or alkyne compounds, in such a way that the Hydrogen atom in the HX electrophile are chemically bonded to the carbon atom containing the least amount of Hydrogen attached to it. This addition process commonly uses catalysts or additive compounds in order to hasten the reaction since the process is quite expensive and toxic in nature. Furthermore, there is also a limited number of reactions involved in using the Anti-Markovnikov addition, making its research more difficult to expand and develop.

2. The nano carrier needs to remain in suspension in H2O, PBS, human serum, etc. What type of polymer do you need to use to decorate the surface of the nanocarrier to achieve this goal? In order to maintain the nanocarrier in suspension in water, Phosphate-Buffered Saline (PBS), human serum a suitable solution a polymer is needed on its surface. The polymer used needs to accomplish three goals. The polymer needs to decorate the nanocarrier surface to enhance suspension and secondly, to prevent protein absorption. Another characteristic is that the polymer evades the immune system. PLGA poly(lactic-co-)glycolic ...

Abstract

The experiment conducted is a palladium catalyzed coupling of a terminal alkyne to 4-Iodonitrobenzene. 1.25 mL of 95% ethanol was added along with 93mg of 4-Iodonitrobenzene, 80mg piperazine hexahydrate and 4 mg CuI, in a 5mL clean and dry conical vial plus spinvane. 80 µL (density 0.898 g/mL) of tetrahydro-2-(2-propynyloxy)-2H-pyran was added to the solution through an automatic pipette. To this add 3 mg of Pd(OAc)2, refluxed and stirred under a water cooled condenser for half an hour until it turned dark brown. The reaction mixture was then poured into a clean and dry evaporating dish and heated gently with a ...
