(
Elsevier
, 2020 , Article)
Flexible membranes of poly(vinyl alcohol) (PVA) polymer and CuO nanoparticles for x-ray detection applications are reported in this work. PVA represents a polymer matrix for nanoparticles, and its flexibility and electrical ...
First principle investigation of H2Se, H2Te and PH3 sensing based on graphene oxide
(
Elsevier
, 2020 , Article)
Detecting toxic gases is of great importance to protect our health and preserve the quality of life. In this work, graphene (G) and graphene oxide with three different modifications (G–O, G–OH, and G–O–OH) have been used ...
DFT investigation of H2S adsorption on graphenenanosheets and nanoribbons: Comparative study
(
Elsevier
, 2020 , Article)
Graphenenanosheet (GNS), armchair graphenenanoribbon (AGNR), and zigzag graphenenanoribbon (ZGNR) systems were investigated by first principle calculations using the density functional theory (DFT). The DFT calculations ...

Laplace approximation, penalized quasi-likelihood, and adaptive Gauss-Hermite quadrature for generalized linear mixed models: Towards meta-analysis of binary outcome with sparse data
(
BMC
, 2020 , Article)
© 2020 The Author(s). Background: In meta-analyses of a binary outcome, double zero events in some studies cause a critical methodology problem. The generalized linear mixed model (GLMM) has been proposed as a valid ...
