Cellular uptake pathways of sepiolite nanofibers and DNA transfection improvement

open access: yesScientific Reports, 2017
Sepiolite is a nanofibrous natural silicate that can be used as a nanocarrier because it can be naturally internalized into mammalian cells, due to its nano-size dimension.

Recent Advances in Catalytic Conversion of Bioethanol to 1,3-Butadiene: Reaction Mechanism, Catalyst Design, and Process Scalability. [PDF]

open access: yesChemSusChem
Catalytic conversion of ethanol to 1,3‐butadiene (BD) can proceed via one‐step and two‐step routes. In the one‐step process, pure and metal‐modified MgO–SiO2 catalysts enable direct ethanol transformation to BD, while ZrO2‐based catalysts drive the two‐step pathway.

Effect of high temperature on sepiolite – hydraulic lime mortar [PDF]

open access: yes, 2015
Sepiolite is a natural clay mineral consisting of magnesium hydrosilicate. High surface area and micropores which form micro structure of sepiolite play an important role for the sepiolite to be used as a binder in the construction sector.
