APPROACHES TO INNOVATION: The need for consistency
(Elsevier, 2021)
The term “innovation” is core to modern science and society with respect to novelty, creation and added value, yet it is also a source of misunderstandings. We aim herein at the clarification of the different approaches ...
Insight into the role of guanidinium and cesium in triple cation lead halide perovskites
(Wiley, 2021)
The overall impact of the partial replacement (5–15%) of methylammonium (MA)in the MAPbI3perovskite by cesium or guanidinium (Gua) cations to fabricatethinfilms of triple cation CsxGuayMA1–x–yPbI3perovskites is studied.The ...
Characterization of a self-assembled monolayer of O-(2-Mercaptoethyl)-O′-methyl-hexa(ethylene glycol) (EG7-SAM) on gold electrodes
(Elsevier, 2021)
The modification of surfaces by polyethylene glycol (EGn) is an approach used to reduce the antifouling effects of these materials in a biological medium. It has been found that the packing density and conformational order ...
Distinct thermoresponsive behaviour of oligo- and poly-ethylene glycol protected gold nanoparticles in concentrated salt solutions
(Royal Society of Chemistry, 2021)
In this work, the methoxy terminated oligo- and polyethylene glycol of different chain lengths (EGn, n ¼ 7,
18, 45 and 136) is grafted on AuNP surfaces under conditions where they attain maximum grafting densities.
These ...
Effective replacement of cetyltrimethylammonium bromide (CTAB) by mercaptoalkanoic acids on gold nanorod (AuNR) surfaces in aqueous solutions
(Royal Society of Chemistry, 2020)
The highly packed cetyltrimethylammonium bromide (CTAB) bilayer built up on the surface of gold nanorods (AuNRs) when
synthetized by the seed-mediated procedure hampers the complete ligand exchange under experimental ...
