Effective scintillation materials based on solid solutions ZnS1–xTex and perspectives of their application [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2011 The optimal technological regime of formation ZnS1–xTex solid solution at spacing 0,0≤х≤0,1 has been determined, and has been shown that fritting in hydrogen atmosphere results in more rapid reaction in comparison to argon due to chemical-thermal etching

Interpretation of the unprecedentedly long-lived high-energy emission of GRB 130427A
, 2013 High energy photons (>100 MeV) are detected by the Fermi/LAT from GRB 130427A up to almost one day after the burst, with an extra hard spectral component being discovered in the high-energy afterglow. We show that this hard spectral component arises from

GRB Spectral Hardness and Afterglow Properties [PDF]
, 2000 A possible relationship between the presence of a radio afterglow and gamma-ray burst spectral hardness is discussed. The correlation is marginally significant; the spectral hardness of the bursts with radio afterglows apparently results from a ...

Designing Physical Unclonable Functions From Optically Active Materials
Advanced Materials, EarlyView.Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Central engine afterglow of Gamma-ray Bursts
, 2007 Before 2004, nearly all GRB afterglow data could be understood in the context of the external shocks model. This situation has changed in the past two years, when it became clear that some afterglow components should be attributed to the activity of the ...
