Design of High‐Performance MnCo1.5Cu0.5O4 Spinel Contact Material with Optimized Electrical Conductivity and Thermal Stability for Solid Oxide Electrolysis Cells by Cu Doping

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cu‐doped spinel MnCo1.5Cu0.5O4 exhibits excellent conductivity and stability as SOC contact material. After 1000‐h aging at 850 °C, the contact layer maintains a 10 mΩ cm2 ASR value, and a single‐cell stack achieves a H2O/CO2 co‐electrolysis power density of 0.52 W cm−2.

Black phosphorus‐based photothermal disruption of cancer‐associated fibroblast barriers and tumor‐associated macrophage targeting to enhance anti‐PD‐L1 immunotherapy in triple‐negative breast cancer

open access: yesInterdisciplinary Medicine, EarlyView.
MBB modulates the TNBC tumor microenvironment by targeting TAM/CXCL1 and facilitates anti‐PD‐L1 therapy by disrupting CAF barriers via its photothermal effect. This combined strategy subsequently enhances the efficacy of PD‐L1 mAb and suppresses TNBC progression, metastasis, and recurrence.

Rheological Characterization and Multi‐Regime Viscosity Modeling of Diluted Polyethylene Mixtures

open access: yesPolymer Engineering &Science, EarlyView.
This study maps the flow behavior of low‐density polyethylene in a recycling solvent from dilute solutions to entangled melts. By integrating time–concentration and time–temperature superposition, and coupling three complementary rheometry methods, a unified semiempirical model accurately predicts steady‐shear viscosity over nine decades of viscosity ...

In Situ Alloying of H13 Tool Steel With TiC via PBF‐LB/M

open access: yessteel research international, EarlyView.
H13 tool steel is in situ alloyed with titanium carbides (TiC) in amounts up to 30 wt.%. This approach offers the advantage that the carbides melt only partially during processing, preventing excessive carbon enrichment of the steel matrix. The resulting microstructure consists of coarse, undissolved and fine, reprecipitated carbides, leading to grain ...
