industrial production of thermoset composite components involves the application of a vacuum bagging and autoclave pressure to minimize void percentage, usually to less than 5%. phenolic resin systems generate water as a reaction byproduct via condensation reactions during curing at elevated temperatures. in this paper, vacuum bagging and simple manufactured autoclave curing systems are used fo...
The lack of readily available sterilization processes for medicine and dentistry practices in the developing world is a major risk factor for the propagation of disease. Modern medical facilities in the developed world often use autoclave systems to sterilize medical instruments and equipment and process waste that could contain harmful contagions. Here, we show the use of broadband light-absor...
background and aim: the purpose of this study was to evaluate the effect of autoclave sterilization on the fracture rate of protaper instruments (ex vivo). materials and methods: one hundred shaping and finishing protaper instruments were used in a crown – down technique for cleaning and shaping the mesial canals of extracted mandibular molars using 5.25% naocl for irrigation. in the experiment...

The counter-immunoelectrophoresis (CIE) method of grouping streptococci was more sensitive than the capillary precipitin method. The precipitate was easier to read, and the test was simple to perform and required fewer reagents. An autoclave-Pronase-B extraction procedure is described and was found superior to either acid, Pronase-B, or the autoclave extraction procedures for recovering groupab...
Experiment Section Synthesis of spiral ultrathin-nanosheets with overgrew edge (SUNOE): For NiFe SUNOE, 0.114g NiCl24H2O and 0.060g (NH4)2Fe(SO4)26H2O were weighed and transferred into a 40mLpolytetrafluoroethene autoclave. Then 8 mL ethanol were added to dissolve the salts by sonication. Though the sulfate seemed not fully dissolved, 2mL oleylamine (OAm) was injected into the autoclave, some p...
Introduction: Dental burs are one of the most commonly used materials in dental offices and have, therefore, the highest risk of cross-contamination. Accordingly, sterilization of dental burs is highly recommended. Using the electron microscopy, this study aimed to evaluate the results of different sterilization methods on the uniformity of diamond dental burs and the change in the cutting edge...
Carbonation of magnesiumand calcium-silicate minerals to form their respective carbonates is one method to sequester carbon dioxide. Process development studies have identified reactor design as a key component affecting both the capital and operating costs of ex-situ mineral sequestration. Results from mineral carbonation studies conducted in a batch autoclave were utilized to design and const...
