  1. 1. Comparing different methods of measuring particle size for pharmaceutical excipients

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Jiawen Wang; [2022]
    Keywords : particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

    Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

    Abstract : Att välja rätt strömaterial till mjölkproduktionen är aldrig lätt. Det finns både för och nackdelar med alla typer av strömaterial. Många lantbrukare i Sverige har hälsa och välmående i fokus då det gäller liggkomfort och minskning av skador hos kor. Gödselfiber är ett relativt nytt material som kommit på marknaden. READ MORE

  5. 4. Comparison of in-situ bioremediation of soil contaminated with chlorinated hydrocarbons

    University essay from Högskolan i Halmstad

    Author : Tianyu Qin; [2020]
    Keywords : bioremediation; biostimulation; bioaugmentation; product; chlorinated hydrocarbon;

    Abstract : In recent years, due to the continuous development of machinery, electronics, leather, chemical companies and dry-cleaning industry, more and more chlorinated hydrocarbons accumulate in the soil, causing serious harm to the environment. The accumulation of chlorinated hydrocarbons and the teratogenic, carcinogenic, and mutagenic hazards seriously threaten human health. READ MORE
