Novel Functional Materials via 3D Printing by Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Prenucleation Species Dictate Foreign Ion Incorporation in the Biomineral Precursor Amorphous Calcium Carbonate

open access: yesAdvanced Functional Materials, EarlyView.
ACC forms via aggregating prenucleation clusters that gatekeep its chemical composition. Ion identity steers the path: Ba and Sr substitute Ca in clusters, thereby inhibiting nucleation, with a dose‐dependent switch of Sr to induction. Mg partitions into Mg‐rich and Mg‐poor clusters; the latter form ACC, expelling Mg.

Autonomous generator based on Ni-Mn-Ga microactuator as a frequency selective element

open access: yesEPJ Web of Conferences, 2013
In this work, we suggest the temperature-induced resistivity change at the martensitic transformation in the Ni-Mn-Ga ferromagnetic shape memory alloy as a driving mechanism enabling periodic signal generation. We demonstrated its practical importance by

On magnetic shape memory alloy actuator characteristics

open access: yesJournal of Vibroengineering, 2009
Magnetic shape memory alloys (MSMA) are adaptive materials controlled with a magnetic field. A fast response, large magnetic field induced strain and high damping make MSMAs attractive materials for actuators. The aim of this study was to define the characteristics of a MSMA actuator and evaluate its suitability for vibration control.

A three‐dimensional phenomenological model for Magnetic Shape Memory Alloys

open access: yesGAMM-Mitteilungen, 2011
AbstractWe present a three‐dimensional thermodynamically‐consistent phenomenological model for the magneto‐mechanical behavior of magnetic shape memory materials featuring a cubic‐totetragonal martensitic transformation. Existence of energetic solutions for both the constitutive relation problem and the three‐dimensional quasi‐static evolution problem ...

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

open access: yesAdvanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...
