Understanding Decoherence of the Boron Vacancy Center in Hexagonal Boron Nitride

open access: yesAdvanced Functional Materials, EarlyView.
State‐of‐the‐art computations unravel the intricate decoherence dynamics of the boron vacancy center in hexagonal boron nitride across magnetic fields from 0 to 3 T. Five distinct regimes emerge, dominated by nuclear spin interactions, revealing optimal coherence times of 1–20 µs in the 180–350 mT range for isotopically pure samples.

Measuring the complex behavior of the SO2 oxidation reaction [PDF]

open access: yesComputational Ecology and Software, 2015
The two step reversible chemical reaction involving five chemical species is investigated. The quasi equilibrium manifold (QEM) and spectral quasi equilibrium manifold (SQEM) are used for initial approximation to simplify the mechanisms, which we want to

An integrated population model to project viability of a northern bobwhite population in Ohio

open access: yesEcosphere, 2021
Increased variation in interannual weather due to climate change can exert a powerful influence on the population dynamics of a species. Understanding the influence of severe weather is important for managing weather‐sensitive species.

Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials

open access: yesAdvanced Functional Materials, EarlyView.
A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.

Trans-heteroclinic bifurcation: a novel type of catastrophic shift [PDF]

open access: yesRoyal Society Open Science, 2018
Global and local bifurcations are extremely important since they govern the transitions between different qualitative regimes in dynamical systems. These transitions or tipping points, which are ubiquitous in nature, can be smooth or catastrophic. Smooth

Defects Dynamic in Photo‐Excited CeO2 and their Influence on CO2 Photoreduction

open access: yesAdvanced Functional Materials, EarlyView.
X‐ray photoelectron spectroscopy study under light excitation is presented to track the defect dynamic (Ce4+ to Ce3+) in CeO2. Surface enhanced Raman spectroscopy confirmed the key role of Ce3+ states in controlling charge and energy transfer across the CeO2‐dye molecule interface.

Exploiting Two‐Photon Lithography, Deposition, and Processing to Realize Complex 3D Magnetic Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
Two‐photon lithography (TPL) enables 3D magnetic nanostructures with unmatched freedom in geometry and material choice. Advances in voxel control, deposition, and functionalization open pathways to artificial spin ices, racetracks, microrobots, and a number of additional technological applications.
