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.

To investigate alleviative effect of selenium (Se) on lead (Pb)-induced apoptosis in chicken nervous tissues, 7-day-old chickens were randomly divided into four groups. The control group was fed a standard diet and drinking water. In the Pb and Se/Pb groups, (CH3OO)2Pb was dissolved in drinking water. In the Se and Se/Pb groups, Na2SeO3 was put into the standard diet. Embryonic neurocytes were ...
