The oxidation behavior of molybdenum dis.licide （Mos.2） powders.at 400, 500, and 600℃ for 12 h in air were inves.igated by us.ng X-ray diffraction （XRD） and trans.is.ion electron micros.opic （TEM） techniques. s.gnificant changes.were obs.rved in volume, mas., and color. Es.ecially at 500℃, the volume expans.on was.found to be as.high as.7-8 times. the color changed from black to yellow-white, and the mas. gain was.about 169.34% after 8 h, with s.O2 and MoO3 as.main reaction products. The gains.in volume and mas. were les. at 400 and 600℃ compared with thos. at 500℃, probably due to the les. reaction rate at 400℃ and the formation of s.lica glas. s.ale at 600℃, which would protect the matrix and res.rain the diffus.on of oxygen and molybdenum. Thus. the accelerated oxidation behavior of Mos.2 powder appeared at 500℃ and the volume expans.on was.the s.gn of accelerated oxidation.

The influence of four kinds.of binders.cons.s.ing of paraffin wax （PW）, random-polypropylene （RPP）, high-dens.ty polyethylene （HDPE）, and s.earic acid （s.） on the theological behavior of injection-molded s.C feeds.ocks.was.inves.igated over a temperature range of 150℃ to 180℃ and a s.ear rate range of 4 s.-1 to 1259 s.^-1. The res.lts.s.owed that all the feeds.ocks.exhibited ps.udoplas.ic flow behavior. The wax-bas.d binder of multipolymer components.（PW-RPP-HDPE） exhibited better comprehens.ve rheological properties.compared with the binder of monopolymer components.（PW-RPP or PW-HDPE）. The addition of 5wt% s. to the binder could reduce the vis.os.ty of the feeds.ock but enhance the rheological s.ability by improving the wettability between the binder and the s.C powder. The binder of 65wt% PW ＋ 15wt% HDPE ＋ 15wt% RPP ＋ 5wt% s. was.found to be a better binder for micros.zed s.C injection molding.

The objective of this.s.udy was.to offer a review of previous.works.on Tinos.ora cordifolia(TC) metabolomics.with a highlight on the us. of metabolomics.in comparative evaluations.between varieties.and s.lection of optimum cultivation, collection, and extraction procedures. providing ins.ghts.into pharmaceutical and food product quality monitoring. s.holarly databas.s.were s.arched to gather relevant information on TC's.therapeutic us.fulnes., phytocons.ituent s.udies. metabolomics. and applications. Pub Chem was.us.d to learn the s.ructures.of s.veral of the metabolites. The various.medicinal properties.of TC were extens.vely res.arched. The mos. es.ential portions.of the plant in Ayurvedic medicines.are the s.ems. Bioactive phytochemicals.s.ch as.s.eroidal lactones. alkaloids. diterpenoids. and phenolic compounds.are pres.nt in the roots.and leaves. Metabolomic analys.s.revealed that, in addition to the s.as.n and geographical region of the s.mple collected, the metabolite profiles.of TC als. depend on the parts.of the plant taken as.a s.mple and als. the plant's.s.age of growth. The amounts.of s.condary metabolites.differed between morpho/chemotypes.within the TC s.ecies. Des.ite the fact that res.arch on TC began s.veral decades.ago, the divers.ty of phytocons.ituents.was.not appreciated becaus. of a lack of reliable techniques.for phytochemical fingerprinting. The uncovering of s.veral novel metabolites.was.aided by advances.in chromatography combined with mas. s.ectrometry.
