Research Papers / Solvent to anti-solvent precipitation method; Description of chem-engineering research [2]

Can anyone help me cut down the words

please provide a brief description of your research project:
(50-75 words)
Solvent to anti-solvent precipitation method is used to enhance the dissolution rate of Artemisinin, a poorly water-soluble antimalarial drug. Conditions such as drug concentration, solvent to anti-solvent ratio, stirring rate, flow rate, and temperature were varied to control the size and morphology of the particles produced. To further improve its dissolution properties, polymers-- Poly vinyl pyrrolidone and Polyethylene glycol, and surfactants--sodium dodecyl sulfate and Pluronic F38 were coprecipitated. Solubility test, dissolution test, High Performance Liquid Chromatography, and scanning electron microscopy were conducted to characterize the particles produced and the original particles.

Undergraduate / Letter to the Ministry of Education; Dartmouth:Extracurricular activities/Work experience [4]

Indonesia(a bit weird) just lost its college freshman for one more time, following so many cases that had happened. Freshmen were beaten, humiliated and treated inhumanely by their seniors. The students were frightened. They just knew that nothing was worth fighting for. Every letter to Ministry of Education will be hardly to read and every protest to university will be a future rejection; all they got was nothing but fear.

On laundry room's seat was me with my laptop , (you might want to say I sat in the laundry room with my laptop) writing 'those letters'. I got no fear about the rejection letters, no restlessness for the Ministry of Education, and even too many guts to start an op-ed for newspapers.

Here was(is) the solution I wrote: "How to Resolve Two Indonesian's Major Problems At Once: Violence and Environment". Many people might think that my suggestion was too odd, but I told them what the things they could simply do to solve this violence and the environmental issues at once. My recommendation was "one freshman plants one tree". I clicked the 'send' button and my e-mails were read by Ministry of Education, over a hundred PRs of universities to which I sent the letter, newspaper editors, and some Indians who(whom) I also wrote for after finding out this? country was facing the same thing. I might be too naïve, but I did what I should do. The reply about forwarding the email to national forum satisfied me, but the most important thing was that I had found the real meaning of my timeless work: writing.
