Insight into the Internal Structure of Biogenic, Synthetic and Geological Apatite by Electron Microscopy and X‐Ray Scattering

open access: yesAdvanced Functional Materials, EarlyView.
Apatite occurs in many forms in nature, e.g. in teeth and geological minerals. Internally, biological apatite contains nanocrystals that are also found in synthetically prepared calcium phosphate nanoparticles which are used in biomedicine, e.g. for gene and drug delivery and for bone regeneration. Abstract Calcium phosphate is the inorganic component (

A Study on Austenite Dynamic Recrystallization of Non-Quenching-Tempering Steel 38MnVS

open access: yesTeshugang, 2012
The austenite dynamic recrystallization process of V-Ti microalloying non-quenching- tempering steel 38MnVS (/% : 0.42C, 0.76Si, 1.33Mn, 0.011S, 0.013P, 0.10V, 0.02Ti) has been studied. The effect of deformation temperature (950-1150 °C ) and strain rate

3D Digital Light Processing of Redox‐Active Polymers for Electrochemical Applications

open access: yesAdvanced Functional Materials, EarlyView.
3D printing of electrochemically switchable conducting polymers is achieved by Digital Light Processing of redox‐active carbazole‐based polymer materials. Complex 2D and 3D architectures including dot arrays and pyramids clearly show the potential for novel 3D switchable electrochemical devices for sensors, electrochromic displays as well as 3D printed

Mechanisms of Dynamic Recrystallization in Aluminum Alloys

open access: yesMaterials Science Forum, 2014
Mechanisms of dynamic recrystallization operating at severe plastic deformation in a wide temperature range are reviewed for aluminum alloys. The main mechanism of grain refinement in all aluminum alloys is continuous dynamic recrystallization (CDRX).

4D Mapping of ZIF Biocomposites for High Protein Loading and Tunable Release Profiles

open access: yesAdvanced Functional Materials, EarlyView.
Systematic four‐dimensional mapping of zeolitic imidazolate framework biocomposites reveals how precursor ratios, total concentration, and washing define crystalline phase, protein loading, and release kinetics. This comprehensive study identifies conditions yielding record loading (∼85%) and precise phase–property correlations.
