Pseudo + quasi SU(3): Towards a shell-model description of heavy deformed nuclei

, 2003
The pseudo-SU(3) model has been extensively used to study normal parity bands in even-even and odd-mass heavy deformed nuclei. The use of a realistic Hamiltonian that mixes many SU(3) irreps has allowed for a successful description of energy spectra and ...

3D Nano‐architected Polymer Shell Enables Reconfigurable Stabilized Blue Phase Soft Crystals

Advanced Functional Materials, EarlyView.
Spherical polymer shells featuring nanostructure of blue phase (BP) disclinations form via in situ photo‐polymerization within BP liquid crystals, providing controlled anchoring for BP nucleation and growth at room temperature and beyond. This architected confinement enhances BP thermal stability over a broad temperature range while enabling dynamic ...

Spin‐Selective Anisotropic Magnetoresistance Driven by Chirality in DNA

Advanced Functional Materials, EarlyView.
It is shown that magnetoresistance (MR) measurements carried out as a function of angular dependence between the magnetic field and a chiral (DNA) interface provide a valuable new insight into the charge transport mechanism associated with the chiral‐induced spin selectivity (CISS) effect.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

Advanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Empirical distributions of galactic $\lambda$ spin parameters from the SDSS

, 2006
Using simple dimensional arguments for both spiral and elliptical galaxies, we present formulas to derive an estimate of the halo spin parameter $\lambda$ for any real galaxy, in terms of common observational parameters. This allows a rough estimate of $\
