Experimental Research on Formation of Large Mass Debris Bed at Severe Nuclear Accident

Yuanzineng kexue jishu, 2023
In a severe accident, the molten core material enters the lower head with water or the reactor cavity is cooled and forms a debris bed. The types of the debris bed formed under different conditions are different, including loose granular, or agglomerated

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

Advanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.

A Kinetic Study on Combustible Coastal Debris Pyrolysis via Thermogravimetric Analysis

Energies, 2019
Coastal debris has recently emerged as a serious environmental pollution problem. Coastal debris can be treated using pyrolysis because it consists mainly of combustible materials like plastics (e.g., polyethylene (PE), polypropylene (PP), nylon) and ...

Combating VEGFA‐siRNA‐Induced Metabolic Reprogramming via Glucose Utilization Deprivation

Advanced Science, EarlyView.
An ionizable lipid nanoparticle co‐delivers VEGFA siRNA and glucose oxidase to tumors to counteract VEGFA knockdown‐induced, glutamine‐driven metabolic compensation. Enzymatic glucose consumption reverses the adaptive pathways and restores metabolism toward baseline, thereby sensitizing tumors to therapy.
