Chemical vapour deposition enables the synthesis of thin films of microporous metalorganic frameworks on a broad range of substrates and on high-aspect-ratio features.
This month marks ten years since the general principles of DNA origami were established, a technique that changed the field of DNA nanotechnology and that promises new physical and biomedical applications.
In the last few years, the advent of metal halide perovskite solar cells has revolutionized the prospects of next-generation photovoltaics. As this technology is maturing at an exceptional rate, research on its environmental impact is becoming increasingly relevant.
Analysis of the magnetic domain-wall motion in a nanostructured magnetic system with strong spin–orbit coupling shows that the energy dissipation can be chiral when the inversion symmetry is broken.
Optimizing the electronic functionality of a thermoelectric molecular junction depends on both the chemistry of the molecule and external environmental conditions.
Thin and continuous films of porous metal–organic frameworks can now be conformally deposited on various substrates using a vapour-phase synthesis approach that departs from conventional solution-based routes.
In atherosclerotic plaques, patterns of calcification — which have profound implications for plaque stability and vulnerability to rupture — are determined by the collagen's content and patterning throughout the plaque.
Biophysical factors in an optimized three-dimensional microenvironment enhance the reprogramming efficiency of human somatic cells into pluripotent stem cells when compared to traditional cell-culture substrates.
A review on toroidal excitations, from static toroidal moments in condensed matter, to dynamic toroidal multipoles demonstrated experimentally with metamaterials.
Structural inversion asymmetry in magnetic materials leads to a dissipative chiral damping mechanism. This mechanism is evidenced in the field-driven domain-wall motion in perpendicularly magnetized asymmetric Pt/Co/Pt trilayers.
The insertion of a few unit-cell-thick EuTiO3 layers at the interface between LaAlO3 and SrTiO3 leads to the formation of an electric-field-tunable quasi-two-dimensional electron system where ferromagnetism and superconductivity coexist.
The electronic interaction between deposited metal nanoparticles and their support material can influence their functionality. Here, a quantification of the charge transfer between platinum nanoparticles and a ceria support is presented.
The thermoelectric response of a fullerene–gold electrode single-molecule junction has been studied in a scanning tunnelling microscope. The junction exhibits positive and negative thermopower, dependent on molecule orientation and applied pressure.
In polymer-based nanocomposites the polymeric phase is often confined between stiff inorganic phases. The effect of this confinement on mechanical properties is assessed.
The critical concentration of dopants required to trigger an insulator-to-metal transition in films of semiconductor nanocrystals has been calculated, and experimentally verified with highly doped silicon nanocrystal films.
The authors show that thin films of microporous metal–organic frameworks can be deposited on a broad range of substrates and on high-aspect-ratio features by means of chemical vapour deposition.
The absorption and desorption mechanism of hydrogen in palladium nanoparticles is complex. Based on thermodynamic considerations a mechanism consistent with an interfacial model different from bulk Pd behaviour is now proposed.
The commitment and differentiation of human mesenchymal stem cells encapsulated in synthetic hydrogels that mimic the stiffness of adult-stem-cell niches can be switched by changing the hydrogel’s onset of stress stiffening.
The confinement imposed by the three-dimensional microenvironment promotes the induction of pluripotency in somatic cells through an accelerated mesenchymal-to-epithelial transition and increased epigenetic remodelling.
Tissue-adhesive scaffolds made by the conjugation of RNA triple helices to dendrimers lead to ∼90% shrinkage of tumours two weeks after implantation in a triple-negative breast cancer mouse model.
