Advanced Materials, EarlyView.A molecular motor with four‐state dynamic chirality is integrated into liquid crystals, enabling quadruple sequential helix inversions and high helical twisting power. Due to high motor efficiency, the supramolecular helicity can be controlled by near‐infrared light via upconversion nanoparticles, resulting in a robust, multistate, photoresponsive soft

The complete spectrum of the area from recoupling theory in loop quantum gravity
, 1996 We compute the complete spectrum of the area operator in the loop representation of quantum gravity, using recoupling theory. This result extends previous derivations, which did not include the ``degenerate'' sector, and agrees with the recently computed

Smooth Quantum Gravity: Exotic Smoothness and Quantum Gravity [PDF]
, 2016 Over the last two decades, many unexpected relations between exotic smoothness, e.g. exotic $\mathbb{R}^{4}$, and quantum field theory were found. Some of these relations are rooted in a relation to superstring theory and quantum gravity. Therefore one would expect that exotic smoothness is directly related to the quantization of general relativity. In

Aqueously Upcycled Lignin with Emergent Tribonegativity for Skin‐Integrated Triboelectronics
Advanced Materials, EarlyView.Aqueously upcycled lignin is transformed into a printable ink that self‐assembles into a nanotextured surface during printing with the highest reported biopolymer‐based tribonegativity. The resulting skin‐integrated triboelectric sensor enables high‐fidelity cardiovascular monitoring and objective mental workload classification, demonstrating a ...

Quantum isolated horizons and black hole entropy
, 2012 We give a short introduction to the approaches currently used to describe black holes in loop quantum gravity. We will concentrate on the classical issues related to the modeling of black holes as isolated horizons, give a short discussion of their ...

BARRIERS IN QUANTUM GRAVITY [PDF]
, 1994 I discuss recent progress in our understanding of two barriers in quantum gravity: $c > 1$ in the case of 2d quantum gravity and $D > 2$ in the case of Euclidean Einstein-Hilbert gravity formulated in space-time dimensions $D >2$.

Nuclear Physics B, 2020 We define a three-dimensional quantum theory of gravity as the holographic dual of the Liouville conformal field theory. The theory is consistent and unitary by definition. The corresponding theory of gravity with negative cosmological constant has peculiar properties. The quantum theory has no normalisable AdS3 vacuum. The model contains primary black

Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions
Advanced Materials Interfaces, EarlyView.Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...
