Resistance of Alkali-Activated Slag Concrete to Chloride-Induced Corrosion

Advances in Materials Science and Engineering, 2015
The corrosion resistance of steel in alkali-activated slag (AAS) mortar was evaluated by a monitoring of the galvanic current and half-cell potential with time against a chloride-contaminated environment.

Influences of Fly Ash, Slag and Silica Fume on Electrochemical Chloride Removal Treatment with Simultaneous Migration of Silicate Ion

International Journal of Electrochemical Science, 2018
The paper aims to investigate the effects of fly ash (FA), slag (SL) and silica fume (SF) on the electrochemical chloride removal treatment with simultaneous migration of silicate ion, which was to alienate the Cl- from the reinforcement and inject SiO32-

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis

Advanced Science, EarlyView.
Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

Advanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Cross-sectional temperature analysis method of slab track based on detailed evaluation of solar radiation and long-wave radiation

Nihon Kikai Gakkai ronbunshu
In some slab tracks in cold regions, freeze-thaw cycle causes frost damage to the slab track filling layer. To evaluate this phenomenon, we proposed a weakly coupled analysis method of heat balance calculation on the slab track surface and heat ...

Copper Depletion Nanoparticles Potentiate Cancer Immunotherapy by Avoiding Innate and Adaptive Immune Resistance

Advanced Science, EarlyView.
A mitochondria‐targeted copper depletion nanoplatform (CYN‐CDA@Alb) was developed to selectively disrupt tumor mitochondria copper, which then reprogrammed the tumor immune microenvironment by depressing PD‐L1 and CD47 expression simultaneously. By doing this, CYN‐CDA@Alb reversed radiotherapy‐induced immune tolerance, showing the potential usage of ...
