A novel inexpensive method for preparation of silk nanofibers from cocoons

AbstractIn the present study , a novel method for the production of silk nano fibers are presented . In this way , a mechanical and easy technique is used instead of toxic and costly chemical methods . Also , the separation of silk nano fibers from the cocoon was carried out by mechanical homogenizer and probe ultrasonic homogenizer . After the preparation of silk nanofibers , the product was c...

Influence of Salinity, Surfactants and Power of Ultrasonic Homogenizer on Droplet Size Distribution of Crude Oil/Water Emulsions

روش ساده اسپکتروفتومتری برای اندازه گیری فعالیت آنزیم پکتین استراز پوست پرتغال

The objective of this investigation is to measure pectinesterase activity by a simple method. The assay is done at 25°C. Oranges were obtained at a local supermarket in winter. They were peeled and 5 gr sections of the peeled tissue were homogenized in 10% NaCl and 0.5 M phosphate buffer in a homogenizer. The homogenates were centrifuged at 3500 rpm for 20 min. The supernatants were collected, ...

Evaluation of a constructed head phantom response in comparison with RANDO head phantom in the same gamma field

Human tissue equivalent phantoms are widely used in medicine. They are used for dosimetry, calibration of medical devices, and quality control of radiotherapy equipment, as well as training students. Regarding to development of radiotherapy techniques for treatment of cancers and also development of educational centers in the country, the human equivalent phantoms are needed. Several phantoms h...
