CO2‐Responsive Smart Wood Scaffold for Natural Organic Matter Removal without Secondary Pollution

Advanced Materials, EarlyView.
A CO2‐responsive smart wood scaffold is developed for sustainable water purification, achieving efficient natural organic matter (NOM) removal and microbial disinfection without secondary pollution. The CO2‐responsive polymer coating undergoes protonation upon CO2 exposure, enabling strong cation−π interactions with NOM.

Considerations on Quantum Gravity Phenomenology [PDF]

Universe 2021, 7(11), 439, 2021
I describe two phenomenological windows on quantum gravity that seem promising to me. I argue that we already have important empirical inputs that should orient research in quantum gravity.

KPZ Formulas for Weyl-Invariant Induced Gravity and Topologically Massive Gravity [PDF]

Nucl.Phys.Proc.Suppl. 57 (1997) 276-279, 1997
I discuss the applicability in Weyl-invariant induced gravity and topologically massive gravity of certain formulas originally derived by Knizhnik, Polyakov, and Zamolodchikov in the context of diffeomorphism-invariant induced gravity.

3D Printed Magnetic Origami Scaffolds for Guided Tissue Assembly

Advanced Materials Interfaces, EarlyView.
3D‐printed magnetic origami scaffolds enhance 3D coculture by directing cell proliferation pre‐folding, restricting expansion for controlled growth within the channel, and spatially and temporally promoting 3D multicellular dissemination post‐folding.

The information metric on the moduli space of instantons with global symmetries

Physics Letters B, 2016
In this note we revisit Hitchin's prescription [1] of the Fisher metric as a natural measure on the moduli space of instantons that encodes the space–time symmetries of a classical field theory. Motivated by the idea of the moduli space of supersymmetric

Efficient and Realistic Brain Simulation: A Review and Design Guide for Memristor‐Based Approaches

Advanced Materials Technologies, EarlyView.
Memristor‐based emulation of Hodgkin‐Huxley neuron models is investigated, by defining the ideal device characteristics needed for accurate ion‐channel representation and reviewing existing works targeting memristive replication of biological realistic neural behavior.

Mimicking Symmetry‐Breaking Einstein Ring by Optical Lens

Advanced Photonics Research, EarlyView.
This article uses an optical lens to emulate the gravitational lensing effect and observe the Einstein ring (ER) patterns. The symmetry‐breaking ER, i.e., Einstein cross, is observed utilizing a rotation‐symmetry‐breaking hemi‐ellipsoid lens. Deformed Einstein cross patterns induced by noncollinearly alignment of the light source–lens–observer are ...

Quantum state correction of relic gravitons from quantum gravity [PDF]

Phys.Rev.D55:4791-4794,1997, 1996
The semiclassical approach to quantum gravity would yield the Schroedinger formalism for the wave function of metric perturbations or gravitons plus quantum gravity correcting terms in pure gravity; thus, in the inflationary scenario, we should expect correcting effects to the relic graviton (Zel'dovich) spectrum of the order (H/mPl)^2.

Functional Optical Fibers with Tailored Side Emission from Modified Rod‐in‐Tube Preforms

Advanced Photonics Research, EarlyView.
A modified rod‐in‐tube method enables fabrication of functional optical fibers with tailored light‐diffusing properties. The approach incorporates optically active species at a well‐defined radial position within an otherwise homogeneous fiber core. Using lanthanide ions and noble metal nanoparticles as active species demonstrates wavelength conversion
