Making Photoresponsive Metal–Organic Frameworks an Effective Class of Heterogeneous Photocatalyst

Advanced Functional Materials, EarlyView.
This review summarizes photoresponsive MOFs for photocatalytic applications, focusing on their capacity to enhance light harvesting, charge transfer, and surface reactions. While existing studies provide foundational insights, emerging characterization techniques enable a deeper understanding of photoresponsive MOFs.

Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level

Advanced Functional Materials, EarlyView.
High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...

Higher group Weyl symmetry

Physics Letters B
We study a higher group analog of the Weyl symmetry in four-dimensional quantum field theories. A typical example is that the modified transformation of the 2-form background gauge field replaces the operator-valued Weyl anomaly associated with gauging ...

Improving the Capacity Retention of Poly(vinylphenothiazine) as Battery Electrode Material by Pore Size Engineering of Porous N‐Doped Carbon Nanospheres as Conductive Additive

Advanced Functional Materials, EarlyView.
By using (meso)porous N‐doped carbon nanospheres with tailored intraparticle porosity and constant particle size as conductive carbon in PVMPT‐based organic battery electrodes, the complete volume of the carbon is accessible for the immobilization of PVMPT, resulting in high accessible specific capacities while maintaining a good rate capability and ...

Anomalies and gauge symmetry

Nuclear Physics B, 1984
Abstract Anomalies are known to have an intrinsic geometrical meaning. Using a formalism where the gauge condition is never made explicit we reanalyze the gauge theory anomaly problem. By requiring simultaneously the BRS and anti-BRS invariances, we do not need to use in our study the gauge dependent anti-ghost equation of motion.

Protecting the axion with local baryon number

Physics Letters B, 2018
The Peccei–Quinn (PQ) solution to the Strong CP Problem is expected to fail unless the global symmetry U(1)PQ is protected from Planck-scale operators up to high mass dimension.

Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States

Advanced Functional Materials, EarlyView.
The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.
