Open AccessMemristive and neuromorphic behavior in a LixCoO2 nanobattery
The phenomenon of resistive switching (RS), which was initially linked to non-volatile resistive memory applications, has recently also been associated with the concept of memristors, whose adjustable multilev...

Time-resolved in-situ X-ray diffraction study of the formation of 3D-hexagonal mesoporous silica films
Highly oriented 3D-hexagonal silica thin films have been produced on silicon substrates by dip-coating technique, using cetyltrimethylammonium (CTAB) bromide as structuring agent. For the first time, time-reso...

Chain orientation in natural rubber, Part II: 2H-NMR study
Stress-induced crystallisation (SIC) and stress-induced melting (SIM) in natural rubbers (NR), unfilled and filled with carbon black (CB) have been studied by 2H-NMR measurements. Various materials have been swol...

Vibrational coherence of self-organized silver nanocrystals in f.c.c. supra-crystals
Fabrication of devices from inorganic nanocrystals normally requires that they are self-organized into ordered structures. It has now been demonstrated that nanocrystals are able to self-organize in a 'supra'-...

A First Insight in the Mechanisms Involved in the Self-Assembly of 2D-Hexagonal Templated SiO2 and TiO2 Mesostructured Films During Dip-Coating
Since mesoporous materials can be prepared by combining the sol-gel chemistry and the structuring effect of surfactants, they have attracted attention for application in various high technology fields. The pre...

Disorder in Solids Studied on an Ultrashort Timescale using Femtosecond X-Ray Diffraction
We’ve studied the sub-picosecond response of an organometallic Langmuir-Blodgett film to an ultrashort laser excitation using ultrafast time-resolved x-ray diffraction. The ultrafast and monochromatic Kα x-ray so...

Structural Study of the Topochemical Polymerization of Two Diacetylenes
Some structural features of the mechanism of thermal polymerization of two diacetylenes, PTS and DNP, are reviewed. It is shown that the reaction proceeds homogeneously with polymer chains growing randomly in ...
