We show for the first time that hydrophilic molecules undergo to highly structured confinements as compared to hydrophobic ones. We also observe that while the latter promotes dehydration, slowly expelling water molecules from the single-wall carbon nanotubes (SWCNT) cavity, the hydrophilic confinement reveals a well ordered organization of water molecules and enhances water mobility.

An enormous positive diamagnetic effect is observed in magneto-photoluminescence spectra when an electron in a wetting layer combines with a hole in a quantum dot, whereas the recombination of electrons and holes in a quantum dot of the coupled system results in an unusual negative diamagnetic effect. The electron wavefunction extent-dependent properties of emitted photons in the wetting layer indicate the coupling between systems of different dimensionality.

Two-dimensional materials are promising for near-future applications in flexible devices; however, defects, i.e., grain structures in materials grown by chemical vapor deposition, are a problematic issue that hinders the industrial application. We suggest an innovative technique to discern the exact location of the grain boundaries and fabricate devices based on such information. As a result, by avoiding grain boundaries, high-quality photodetectors can be produced.

We report a method for synthesizing composite inks of silver nanowires and tin oxide nanoparticles that allows for conductive nanowire networks to be deposited directly from solution without the need for any annealing steps or network formation treatments. Coordination between individual nanowires and nanoparticles appears to be mediated by dilute concentrations of ammonia in the solution, which allows for partially conductive ligands such as oxide nanoparticles to replace the insulating polyvinylpyrrolidone layer that initially coats silver nanowires after synthesis.

DNA has the capability to recover after absorbing ultraviolet (UV) radiation, for example, by autoionization (AI). Single-wall carbon nanotube (SWNT) two-color photoluminescence spectroscopy was combined with quantum mechanical calculations to explain the AI in self-assembled complexes of DNA wrapped around SWNT.

Onion-like Pt每Cu alloy nanocrystals were synthesized by a ※low-temperature interface-induced assembly§ approach. A bending mechanism is proposed to elucidate the appearance of twin defects and lattice expanding (contraction) based on aberration corrected scanning transmission electron microscopy analysis.
