IN-SITU REACTIVE SYNTHESIS OF FULL DENSE SI2N2O BY INCORPORATING OF AMOURPHOUS NANOSIZED SI3N4;EFFECT OF MGO AND Y2O3

In-situ reactive synthesis of full dense Si2N2O by incorporating of Amourphous nanosized Si3N4;effect of MgO and Y2O3

Si2N2O is considered as a new great potential structural/functional candidate in place of Si3N4.The amorphous Si3N4 nanopowder was incorporated into silica sol by adding of MgO and Y2O3 as sintering aid.Synthesized powders were heated by spark plasma sintering at a heating rate of 100 oC/min yielded fully dense compacts at 1550 and 1750 oC for 40 m

Comparison of Spermophilus dauricus gastrointestinal phenotypic flexibility between hibernating and non-hibernating seasons

Traits of the gastrointestinal (GI) tract are phenotypically flexible and seem to reflect the ecological features of animals.The Daurian ground squirrel (Spermophilus dauricus) is a typical fat-storing, hibernating animal.However, information on seasonal GI plasticity in this species is limited.The aim of the present study was to characterize the m
