We aim to provide a quasar sample that is more complete than any previous surveys by using a combined selection technique to reduce the selection ef.ects. Here we present the observational results f.r the X-ray candidates in the f.eld of.the Leo Cluster. We f.und 33 X-ray AGNs in this f.eld of.which 10 are new discoveries. The X-ray data and optical spectra of.these AGNs are given. We also study the near-IR properties of.the X-ray-selected AGNs by using the data f.om 2MASS. Most of.the AGNs in our sample span the color range 0.0〈B-J〈2.5,1.0〈 J-Ks 〈2.0 and 0.5〈H-Ks〈1.2.

This is the third paper in a series connected with our Multiwavelength Quasar Survey. The survey is aimed to provide a quasar sample more complete than any previous survey by using a combined selection technique to reduce selection ef.ects. We present the observational results f.r the X-ray candidates in f.eld f.36. We f.und 15 X-ray AGNs in this f.eld of.which eight are new discoveries. The X-ray data and optical spectra of.these AGNs are given. We give the X-ray candidate selection criteria, which proved to be highly ef.icient in isolating X-ray AGNs.

An eco-f.iendly chemical reduction method was successf.lly used f.r the preparation of.chitosan （CTS） composite f.lms loaded with silver nanoparticles （AgNPs） by self.assembly method using poly（ethylene glycol） as both reducing and stabilizing agent. UV-Vis spectra of.the prepared chitosan loaded silver nanoparticles （CTSLAg） f.lms reveal that f.ll reduction of.silver ions to silver nanoparticles takes place at 90 ℃. The ef.ect of.reaction conditions on the silver nanoparticles f.rmation was investigated using UV-Vis spectrophotometer. The morphology of.the f.lms was tested by scanning electron microscopy （SEM）. The DSC curves showed that the CTSLAg f.lm had a f.vorable compatibility and heat stability. AgNPs were conf.rmed by XRD and UV-Vis spectroscopy. The TEM f.ndings revealed that the silver nanoparticles synthesized were spherical in shape with unif.rm dispersal, and by increasing CTS：PEG ratio larger silver nanoparticles could be obtained. The results of.antibacterial study reveal that the prepared nanoeomposite f.lms exhibited potential inhibition.

The Alpe Arami garnet peridotite of.the Southern Swiss Alps is associated with eclogites and included within quartzof.ldspathic gneisses. Controversy has swirled around the depth of.origin of.this massif.since the 1970s when application of.the newly-developed technique of.thermobarometry suggested a depth of.last equilibration of.greater than 120 kin. Such controversy accelerated in 1996 when we reported microstructural evidence of.extensive precipitation of.ilmenite and spinel f.om olivine and proposed a much greater depth of.origin. Subsequent experiments showed that it was possible to dissolve the observed amount of.TiO2 in olivine, but only at depths in excess of.300 kin, agreeing with the earlier proposal. In 1999 we added new, independent, evidence concerning exsolution of.high-pressure clinoenstatite f.om diopside that in-and-of.itself.required a depth of.origin in excess of.250 km. Subsequently, we also added evidence f.om the surrounding eclogites of.very high pressures and experimental evidence that the pyroxenes included in the amoeboid garnets of.this rock had exsolved f.om a majoritic parent at perhaps even greater pressures. In ref.tation of.the f.rst two of.these observations, suggestions were made that （i） we had made a serious error in our estimate of.how much ilmenite was present in olivine （and theref.re how much TiO2 had been dissolved in olivine）; （ii） the ilmenite had not been exsolved f.om olivine but f.rmer titanian clinohumite had been present and broke down to yield the ilmenite; （iii） the pyroxene exsolved f.om diopside had been high-temperature clinoenstatite. In all three of.these cases, the alternatives of.ered were claimed to be accommodated at low pressures. Here we review the essence of.this controversy and show that the only scenario that can explain all of.the data is the one that we originally proposed; indeed, the more recent data have strongly supported that interpretation and pushed the minimum origin of.the massif.to depths ap
