Determining the validity of cumulant expansions for central spin models

Physical Review Research, 2023
For a model with many-to-one connectivity it is widely expected that mean-field theory captures the exact many-particle N→∞ limit, and that higher-order cumulant expansions of the Heisenberg equations converge to this same limit whilst providing improved

Automation and Active Learning for the Multi‐Objective Optimization of Antibody Formulations

Advanced Science, EarlyView.
Successful antibody formulation necessitates balancing factors such as thermal stability, colloidal stability, and viscosity across a vast excipient design space. This work integrates robotic liquid handling, high‐throughput biophysical characterization, and multi‐objective Bayesian optimization in an iterative closed‐loop Design‐Build‐Test‐Learn cycle.

Process Optimization of Solution Blow Spinning for Poly (N‐Isopropylacrylamide) Fibers

Journal of Applied Polymer Science, EarlyView.
Solution blow spinning has emerged as a safe and scalable technique for fabricating thermoresponsive PNIPAM fibers. The influence of key parameters on jet stability and fiber uniformity is determined through both rheological analysis and statistical process optimization. A Box–Behnken design reveals an optimized window for producing PNIPAM fibers below

PERFECTA Loaded Lipid Cubosomes for 19F‐MRI: Physico‐Chemical Characterization

Chemistry – A European Journal, EarlyView.
Phytantriol‐based cubosomes loaded with PERFCTA, a fluorinated MRI probe, were developed as promising systems for imaging and drug delivery. The nanoparticles showed high PERFECTA encapsulation efficiency, strong fluorine MRI signals, and optimal colloidal stability in biological media.

Fibrilpaint: A Class of Amyloid‐Targeting Peptides

Chemistry – A European Journal, EarlyView.
FibrilPaints are modular peptides engineered to recognize amyloid fibrils. By systematically varying charge, sequence, and termini, their binding behavior can be tuned while retaining recognition. Successful binding ″paints″ fibrils for visualization and opens routes toward targeted degradation and diagnostic applications.

QCD θ-vacuum in a uniform magnetic field

Nuclear Physics B, 2022
We study the θ-vacuum of QCD using two-flavor chiral perturbation theory (χPT) in the presence of a uniform, background magnetic field calculating the magnetic field-dependent free energy density, the topological density, the topological susceptibility ...

Unprecedented Wall‐Atomically Thick Bi5O7Br Nanotubes Embedding Abundant Bi Nanodots Boosting Efficiently Photothermal Coupling Catalytic CO2 Conversion

EcoEnergy, EarlyView.
Atomically thin Bi5O7Br nanotubes embedded with abundant Bi nanodots were constructed as an efficient photothermal catalyst for CO2 conversion. The localized surface plasmon resonance and photothermal effect of Bi nanodots synergistically enhance light harvesting, charge utilization, and reaction kinetics, resulting in significantly improved CO2 to CO ...

Physical stability of RNA–lipid nanoparticles under agitation, freeze–thaw and accelerated stability testing

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The choice of excipient is important in enhancing stability of liquid formulations containing lipid nanoparticles (LNPs) used in RNA delivery where the ability to survive unplanned excursions to higher and lower temperature and vibration is an important attribute.

Topological susceptibility and fourth cumulant in a uniform magnetic field

Nuclear Physics B, 2022
We study the topological susceptibility and fourth cumulant of the QCD vacuum in a background magnetic field (H) using three-flavor chiral perturbation theory (χPT) for arbitrary quark masses and n-flavor χPT with degenerate quark masses.
