Additively Manufactured Diamond for Energy Scavenging and Wireless Power Transfer in Implantable Devices

open access: yesAdvanced Functional Materials, EarlyView.
Additive manufacturing is expanding beyond mechanical prosthetics into microelectronic implants. This work presents a diamond‐titanium hybrid that enables wireless power transfer, localized heating, and flow sensing. The use of additive manufacturing combined with the biocompatibility of the diamond‐titanium hybrid material paves the way toward new ...

Radicular anatomy of permanent mandibular second molars in an Iranian population: A preliminary study

open access: yesDental Research Journal, 2016
Background: Root morphology is of utmost importance to endodontic sciences. Since there are a few studies on the morphology of mandibular second molars' roots, and some anatomical variables are not evaluated before, the aim of this study was to ...

Interaction Effects in a One-Dimensional Constriction

open access: yes, 1998
We have investigated the transport properties of one-dimensional (1D) constrictions defined by split-gates in high quality GaAs/AlGaAs heterostructures.

Apical domain polarization localizes actin-myosin activity to drive ratchet-like apical constriction

open access: yesNature Cell Biology, 2013
Apical constriction promotes epithelia folding, which changes tissue architecture. During Drosophila gastrulation, mesoderm cells exhibit repeated contractile pulses that are stabilized such that cells apically constrict like a ratchet. The transcription

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

open access: yesAdvanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Experimentally Validated Design Principles of D‐Block Transition Metal Single‐Atom Non‐Dissociative Chemisorption Solid‐State Hydrogen Storage Materials

open access: yesAdvanced Functional Materials, EarlyView.
A novel descriptor and a bottom‐up design principle are established to enable the rational design of hydrogen storage materials based on d‐block transition metal single‐atom COFs. By modulating H₂ adsorption through d‐orbital tuning, this approach achieves both high storage capacity and fast kinetics, while revealing a volcano‐type relationship between

Jamming, two-fluid behaviour and 'self-filtration' in concentrated particulate suspensions

open access: yes, 2003
We study the flow of model experimental hard sphere colloidal suspensions at high volume fraction $\Phi$ driven through a constriction by a pressure gradient.
