Soft self-assembly of Weyl materials for light and sound [PDF]
, 2018 Soft materials can self-assemble into highly structured phases which replicate at the mesoscopic scale the symmetry of atomic crystals. As such, they offer an unparalleled platform to design mesostructured materials for light and sound.

Absorption-Dominant Electromagnetic Interference Shielding of Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> MXene-Coated and Fe<sub>3</sub>O<sub>4</sub>-Integrated TPMS Composites with Coupled Gradient Conductivity and Size-Graded Structure. [PDF]
Adv Sci (Weinh)A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

Generalized Gilat-Raubenheimer method for density-of-states calculation in photonic crystals [PDF]
, 2018 Efficient numeric algorithm is the key for accurate evaluation of density of states (DOS) in band theory. Gilat-Raubenheimer (GR) method proposed in 1966 is an efficient linear extrapolation method which was limited in specific lattices.

Monolithic Gyroidal Mesoporous Mixed Titanium–Niobium Nitrides [PDF]
ACS Nano, 2014 Mesoporous transition metal nitrides are interesting materials for energy conversion and storage applications due to their conductivity and durability. We present ordered mixed titanium-niobium (8:2, 1:1) nitrides with gyroidal network structures synthesized from triblock terpolymer structure-directed mixed oxides. The materials retain both macroscopic
