Electronic Modulation of K⁺‐Intercalated Polymeric Carbon Nitride via ─C≡N/─OH Functionalization for Efficient Photocatalytic H2O2 Production

open access: yesAdvanced Science, EarlyView.
K+ is successfully embedded in the PCN interlayers via a high‐temperature polymerization. The incorporation of K+ perturbs the local electronic structure via interaction with nitrogen lone pairs, narrowing the PCN bandgap, which exhibits superior photocatalytic performance, achieving a high H2O2 generation rate both in situ and under sunlight ...

Ultrahigh High‐temperature Capacitive Energy Storage Via Proton Irradiation

open access: yesAdvanced Science, EarlyView.
Proton irradiation concurrently induces enhanced dielectric constant and breakdown field in aromatic polymers with ether bonds, which enables an ultrahigh discharged energy density of 6.9 J cm−3 at above the efficiency of 95% at 150 °C, exceeding current dielectric polymers and nanocomposites.

Fe‐Based Nanocrystalline Magnetic Shielding Cylinder with Subfemtotesla‐Level Magnetic Noise

open access: yesAdvanced Science, EarlyView.
Shields with low magnetic noise are achieved by integrating Fe‐based nanocrystalline magnetic shielding cylinders into shielding systems based on μ‐metal. Benefiting from high permeability and low loss factor, Fe‐based nanocrystalline magnetic shielding cylinders effectively suppress magnetic noise. Notably, the magnetic shielding cylinder with the ten‐

Engineered TIGIT‐Blockade Membrane Vesicles Synergize with Microwave Ablation to Mediate Liver Metastases Eradication

open access: yesAdvanced Science, EarlyView.
Microwave ablation (MWA) represents a highly effective and clinically significant therapeutic modality for the treatment of liver metastases. This study develops engineered cell membrane vesicles to specifically target the transition zone of MWA for liver metastases. This strategy can inhibit VEGF‐mediated immunosuppression, block CD155/TIGIT signaling

Robust C–V Ratio Technique for Profiling Defects in Proton‐Irradiated 4H‐SiC

open access: yesAdvanced Electronic Materials, EarlyView.
A noise‐robust C–V ratio technique is introduced to profile radiation‐induced defects in proton‐irradiated 4H‐SiC Schottky diodes. By using analytical capacitance ratios instead of numerical differentiation, the method directly extracts trap‐density and effective trap‐energy profiles at room temperature.

Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

open access: yesAdvanced Energy Materials, EarlyView.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...

Resilience of Small Beef Packers and the USDA Meat Supply Chain Initiative

open access: yesAgribusiness, EarlyView.
ABSTRACT We focus on the plant‐size resilience relationship among small beef packers during COVID‐19. Defining resilience as the ability to maintain or increase slaughter and non‐resilience as otherwise, we use survey and secondary data to estimate a logit model where resilience is a function of a plant's capacity and age in addition to labor condition
