Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

Advanced Physics Research, EarlyView.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

Spectral Response Modelling of Multilayer Graphene/Quantum Dot Heterostructures

Advanced Physics Research, EarlyView.
The spectral response of a multilayer heterostructure device with multiple layers of graphene and photosensitizers of different bandgaps (ZnO and quantum dots) is simulated and validated with experimental data. Our simulation incorporates photon absorption by the photosensitizers and charge collection by graphene, capturing the photoresponse dependence

Continuous Purification of mRNA Produced by In Vitro Transcription Using High Performance Countercurrent Membrane Purification

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Messenger ribonucleic acid (mRNA) therapeutics produced by in vitro transcription must be purified to remove residual enzymes and free nucleotides. This study examines the use of high‐performance countercurrent membrane purification (HPCMP) for the purification of mRNA therapeutics based on differences in the rate of diffusion across ...

Synthesis of Ligands Containing N-oxide Donor Atoms and Their Assembly into Metallosupramolecular Structures.

, 2013
A series of ligands that contain both N-donor and N-oxide donor atoms have been synthesised and ligands L5, L6, L7 and L8 contain, 4, 6, 5, and 6 donor atoms respectively. The smallest ligand L5 forms a mononuclear complex with Cu2+ ([Cu(L5)(ClO4)2(MeCN)]

From brush conformation to 3D Supraparticles: Programmable self‐assembly of polymer‐grafted nanoparticles in emulsion confinement

Bulletin of the Korean Chemical Society, EarlyView.
This review highlights how the conformational adaptability of polymer‐grafted nanoparticles drives their programmable self‐assembly within 3D emulsion droplets. By coupling brush thermodynamics with soft confinement, these dynamic building blocks form hierarchical supraparticles tailored for advanced plasmonics, compartmentalized catalysis, and stimuli‐
