ChemPhotoChem, EarlyView.Herein, we carried out an in‐depth study into the synthesis, optoelectronic characterisation, and charge carrier dynamics of the bismuth oxobromide/ copper phthalocyanine (BiOBr/CuPc) composite system for UV and visible light photocatalytic nitrogen oxide (NOx) removal on air purification filters.

Solutions of Quantum Gravity Coupled to the Scalar Field [PDF]
Phys.Lett. B406 (1997) 33-36, 1997 We consider the Wheeler-De Witt equation for canonical quantum gravity coupled to massless scalar field. After regularizing and renormalizing this equation, we find a one-parameter class of its solutions.

Holographic signatures of resolved cosmological singularities
Journal of High Energy Physics, 2019 The classical gravity approximation is often employed in AdS/CFT to study the dual field theory, as it allows for many computations. A drawback is however the generic presence of singularities in classical gravity, which limits the applicability of AdS ...

Noûs, EarlyView.Abstract The active/passive distinction, once a hallmark of classical metaphysics, has largely been discarded from contemporary thought. The revival of powers theory has not seen an equally vigorous rehabilitation of the real distinction between active and passive powers. I begin an analysis and vindication with a critique of E.J. Lowe's discussion.

Artificial Gold Enzymes Using a Genetically Encoded Thiophenol‐Based Noble‐Metal‐Binding Ligand
Angewandte Chemie, Volume 137, Issue 12, March 17, 2025.A new class of artificial metalloenzymes containing genetically encoded noble‐metal‐binding sites featuring a non‐canonical thiophenol‐based amino acid, which serves as an excellent soft ligand for binding various noble metals, was developed. The corresponding gold(I) enzyme was characterised, confirming gold binding to the thiophenol, and successfully

The simplicity of physical laws
Noûs, EarlyView.Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

Potential tests of the generalized uncertainty principle in the advanced LIGO experiment
Physics Letters B, 2018 The generalized uncertainty principle and a minimum measurable length arise in various theories of gravity and predict Planck-scale modifications of the canonical position-momentum commutation relation.

4D spherically symmetric time-dependent quantum gravity amplitudes
European Physical Journal C: Particles and FieldsIn these short notes, we compute non-perturbatively the time-dependent quantum gravity amplitudes for a four-dimensional spherically symmetric space-time with space-like and time-like boundaries.

Quantum Cosmology and Black Hole Interiors in Nonsupersymmetric String Theory and Canonical Gravity [PDF]
arXiv, 2023 In this paper we study black hole interior solutions and cosmologies in different dimensions using tools from canonical gravity and nonsupersymmetric string quantum cosmology. We find that the quantum wave functions associated with these solutions can be related to each other by a specific choice of variables.

Latticing quantum gravity [PDF]
Nucl.Phys.Proc.Suppl. 57 (1997) 255-258, 1997 I discuss some aspects of a lattice approach to canonical quantum gravity in a connection formulation, discuss how it differs from the continuum construction, and compare the spectra of geometric operators - encoding information about components of the spatial metric - for some simple lattice quantum states.
