Programmable Multi‐Axially Aligned Aerogels via Sequential Freeze‐Casting for Tailored Anisotropy and Tunable Mechanics

Advanced Science, EarlyView.
Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.

A Pathology‐Instructed Theranostic Platform with Mechanoadaptive and ROS‐Powered Nanobreathing Functions for Precision Myocardial Repair

Advanced Science, EarlyView.
We developed a pH responsive theranostic serum albumin hydrogel named BST, functionalized with MRI and CT probes and loaded with mitochondria targeted CAT‐SOD nanogels, that rapidly self repairs and mechanically stabilizes the infarcted myocardium, releases therapeutic nanogels and albumin under hypoxia induced acidosis to clear mitochondrial ROS ...

Gelation of silk fibroin.

Sen'i Gakkaishi, 1990
Refined silk fibroin obtained from waste cocoons was dissolved in a mixture of ethanol and neutral salt (calcium chloride) solution and the solution thus obtained was centrifuged and then acidified with an organic acid after dialysis. The pH of the resulting solution was in the acid side of the isoelectric point (pl=3.8-3.9).

Current Collector Engineering for New Efficient Bioresorbable Sodium‐Ion Batteries

Advanced Science, EarlyView.
A bioresorbable Na‐ion battery is proposed with Mo or Mg thin‐film current collectors for temporary implants. Mo‐based batteries exhibit superior electrochemical performance and stable cycling compared with Mg counterparts. XPS was used to investigate the Mo/Mg surface oxidation.

CRYSTALLIZATION OF SILK FIBROIN

Sen'i Gakkaishi, 1969
A transparent solution was obtained by treating silk fibroin with dichloroacetic acid for one day at room temperature. The 1% solution gave cloudy precipitates by diluting with the same volume of water.Needle-shaped crystals could be observed under optical microscope in the precipitates dried up on a slide glass at about 60°C.The particles have sizes ...

ON THE SPHERULITES OF SILK FIBROIN

Sen'i Gakkaishi, 1968
On the formation of spherulites in silk fibroin gel obtained from fresh silk gland, the conditions for crystallization such as pH and temperature and the structure of the spherulites resulted under these conditions were examined.1. Spherulites of silk fibroin were observed at temperatures lower than 50°C and the range of pH from 3.0 to 10 except in pH ...

Unraveling Bone‐Skin Crosstalk Enables miRNA Nanoformulation for Cutaneous Neurovascular Reconstruction in Diabetic Mice

Advanced Science, EarlyView.
This study unravels that bone fracture accelerates diabetic wound healing by releasing exosomal microRNA (miR‐130b‐3p). To mimic this bone‐skin crosstalk, we engineered a self‐assembling agomir‐130b‐3p nanocomplex. Delivered via a photocrosslinkable hydrogel, this bio‐inspired therapy provides sustained localized agomir release.
