Cosmological effective Hamiltonian from full loop quantum gravity dynamics
Physics Letters B, 2018 The concept of effective dynamics has proven successful in LQC, a loop-inspired quantization of cosmological spacetimes. We apply the same idea of its derivation in LQC to the full theory, by computing the expectation value of the scalar constraint with ...

Advanced Materials, EarlyView.A new embedded 3D printing (EMB3D) strategy enables in situ polymerization of DCPD/COD‐based inks within a fugitive reactive matrix where the activator in the matrix cures the printed filament. Cured ink properties are tunable through DCPD‐COD comonomer ratios, yielding materials from stiff thermosets to soft elastomers.

Elucidating the Friction Catalytic Lubrication Mechanism of Ag Nanoparticles Loaded on MOFs
Advanced Materials Interfaces, EarlyView.A novel Ag@Co‐BDC nanocomposite lubricating additive is successfully synthesized, which effectively promoted interfacial tribochemical reactions to form a protective tribofilm during friction, resulting in a 16.7% reduction in friction coefficient and a 61.5% decrease in wear rate for base oil.

High Aspect Ratio, Superconducting Vacuum Gap Capacitor NEMS with Plate Distances Down to 32 nm
Advanced Materials Technologies, EarlyView.Fabrication of aluminium vacuum gap capacitor based NEMS is investigated with a free to move top electrode. To avoid collapse of the top electrode vertical stress gradient is controlled through sputter parameters. The result is wafer‐level high‐yield fabrication of vacuum gap capacitors with radii between 7 µm and 30 µm and integrated piezoactuators. A

The Hall Effects of Vortex Light in Optical Materials
Advanced Photonics Research, EarlyView.This article models optical materials as curved spacetime to investigate light propagation, finding that the deflection angle for light with spin σ and intrinsic orbital angular momentum ℓ follows ϑ ∝ 2σ + ℓ$\vartheta \propto 2 \text{&sgr; } + ℓ$.
