Deep Learning Network‐Tailored Microenvironment Matching of 4D Bioprinting Bioactive Scaffolds for Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

Redox Complexity in Sodium Manganese Hexacyanomanganate and Its Influence on Sodium‐Ion Storage Performance

open access: yesAdvanced Energy Materials, EarlyView.
The role of each Mn site in the Na3‐xMn[Mn(CN)6]·zH2O compounds’ redox activity was investigated using a combined experimental–computational approach, which shows that only the low‐spin Mn‐C site undergoes redox changes (Mn1+ to Mn4+), while high‐spin Mn‐N remains unchanged. The study confirms the presence of the Mn1+ intermediate and newly reveals its

ON THE PARTICLE CRUSHING FEATURES OF SANDY SOILS

open access: yesProceedings of International Structural Engineering and Construction, 2020
Previous studies have investigated particle crushing of sandy soils in high-pressure conditions. In practice, the volume shrinkage and decreasing shear strength due to particle crushing around the pile-foundation tip in crushable sandy soils may be more important.

Guideline for High‐Performance Liquid Chromatography Detection of Anthocyanins

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
ABSTRACT Anthocyanins, as water‐soluble natural pigments widely present in plants, have various biological activities such as antioxidation and anti‐inflammatory, and are widely used in the fields of food, cosmetics, and medicine. However, because of the presence of unstable phenolic hydroxyl groups in their structure, they are prone to degradation due
