Cryopreservation would potentially very much facilitate the inventory control and distribution of laboratory-produced organs and tissues. Although simple freezing methods are effective for many simple tissues, bioartificial organs and complex tissue constructs may be unacceptably altered by ice formation and dissolution. Vitrification, in which the liquids in a living system are converted into ...

Development of metallic glasses is hindered by the difficulties in manufacturing bulk parts large enough for practical applications. Spark plasma sintering (SPS) has emerged as an effective consolidation technique formation (BMGs) from melt-spun ribbons. In this study, Mg65Zn30Ca5 ribbons were sintered at prolonged times (15 min to 180 min) via SPS under a pressure 90 MPa and temperature 150 °C...

mold powders are fluxing agents used as raw materials in the steel industry, which play very important role inprocessing stability and final surface quality of a product. surface quality depends particularly on the viscosity and the heat transfer of infiltrated mold flux between the mold wall and the solidified steel shell. heat flux across the interfacial gap depends on thermal properties of s...

Abstract Crystallization, mechanical properties, and workability are all important for the commercialization optimization of silicate glass compositions. However, inter‐relations these properties as a function composition have received little investigation. Soda‐lime‐silica glasses with Na 2 O‐MgO‐CaO‐Al O 3 ‐SiO compositions relevant to commercial manufacture were experimentally studied multip...
