Porous Structures and Phase Separation in Semiconductor Nanoparticles Induced by Low-energy-electronic Excitation

Electronic excitation of H2O by low-energy electron impact.

Hybrid porous material produced by polymerization-induced phase separation.

Herein we demonstrate a new, straightforward method for the synthesis of macroporous hybrid polymers coated with gold nanorods, which are strongly and uniformly attached to the surface of pores.

Janus Supraparticles by Induced Phase Separation of Nanoparticles in Droplets

Adv. Mater. 2009, 21, 1949–1953 2009 WILEY-VCH Verlag G IO N Janus particles are non-centrosymmetric particles with two distinct sides. The two sides may differ in surface wettability or in optical, electrical, or magnetic properties. Depending upon the anisotropic properties, these particles can be used as emulsion stabilizers, analogous to surfactant molecules, optical probes for chemical, bi...

Structural phase transition of aluminum induced by electronic excitation

The dynamics of a structural phase transition induced by interband electronic excitation in aluminum is studied by determining the time evolution of the dielectric constant at 1.55 eV through the measurement of the transient reflectivity induced by an ultrafast pump pulse. The threshold fluence and the time scale for this transition are significantly less than the values necessary for ultrafast...

Spin–orbit induced electronic spin separation in semiconductor nanostructures

The demonstration of quantized spin splitting by Stern and Gerlach is one of the most important experiments in modern physics. Their discovery was the precursor of recent developments in spin-based technologies. Although electrical spin separation of charged particles is fundamental in spintronics, in non-uniform magnetic fields it has been difficult to separate the spin states of charged parti...
