Fewstep synthesis, thermal purification and structural characterization of porous boron nitride nanoplatelets
(2016)Hexagonal boron nitride (hBN) nanoplatelets with 99 wt.% purity, 900 to 2000 nm particle width, 30 to 90 nm particle thickness, 213 m2/g specific surface area (SSA), 66% micropore SSA and 0.85 nm average pore size were ...

Article
Finite segment model complexity of an EulerBernoulli beam
(2015)A common approach for modeling the dynamic behavior of distributed parameter systems is the approximation through finitesegment models. These models are able to accurately predict the dynamic behavior of the system given ...
