The morphogenetic relationship between early patterning and polarity formation is of fundamental interest and remains a controversial issue in preimplantation embryonic development. We use a label-free three-dimensional (3-D) imaging technique of full-field optical coherence tomography (FF-OCT) successfully for the first time to study the dynamics of developmental processes in mouse preimplanta...

Eggs from (C57B1 x A a G ^ mice were activated by treatment with hyaluronidase, which removed the follicle cells, and cultured in vitro. Observations were made 6-8 h after hyaluronidase treatment to determine the frequency of activation and the types of parthenogenones induced. Cumulus-free eggs resulting from hyaluronidase treatment were incubated for 2\ h in culture media of various osmolarit...

Few studies have combined molecular- and macroscopic-scale investigations with surface complexation model (SCM) development to predict trace metal speciation and partitioning in aqueous systems over a broad range of conditions. In this work, an extensive collection of new macroscopic and spectroscopic data was used to assess the ability of the modified triple-layer model (TLM) to predict single...

Sensitive and fast detection of neutrons gamma rays is vital for homeland security, high-energy physics, proton therapy. Fast-neutron detectors rely on light organic scintillators, γ-ray use heavy inorganic scintillators semiconductors. Efficient mixed-field using a single material highly challenging due to their contradictory requirements. Here we report hybrid perovskites (C8H12N)2Pb(Br1−xClx...

Compounds of the general formula (CH3NH3)„_i(CH3C6H4CH2NH3)2Pb„X3„+i, where X = I, Br, Cl and n= 1,2, 3,..., were prepared and characterized analytically and spectroscopically. Moreover, (CH3C6H4CH2NH3)2PbX4 and (C H ^N H jX C ^C e^C H zN H jhP b il? were charac­ terized by X-ray crystal structure analysis. Their optical absorption and photoluminescence spectra exhibit excitonic bands, even at ...

We report a novel cluster, [{Pt(C6F5)(bzq)}2Pb(Spy)2] 1, that displays reversible vapoluminescence to specific organic vapours; this behaviour can be related to the stereochemical activity of the lone pair around the Pb(II) in the ground state and to the distinct distortion of the coordination environment (1 and 1-solvent) upon photoexcitation.
