An Implanted Tooth That Can Feel

Advanced Science, EarlyView.
To endow the implanted tooth with masticatory perception, herein we demonstrate that a 3D‐printed piezoelectric‐core/robust‐sheath implanted tooth can rebuild the sensing feedback, serving as “mechanoreceptors” in converting the mechanical chewing force to electrical signals, and up to brain through surrounding alveolar nerve system.

Development of Coatings for Tantalum Alloy Nozzle Vanes [PDF]

A group of silicide coatings developed for the T222 tantalum-base alloy have afforded over 600 hours of protection at 1600 and 2400 F during cyclic exposure in air. These coatings were applied in two steps.

Dysregulation of the PATZ1/CTCF Balance Silences ZBTB20 to Drive Melanoma Progression

Advanced Science, EarlyView.
This study uncovers a new oncogenic mechanism in melanoma. The transcription factor PATZ1 competes with the architectural protein CTCF for DNA binding, thereby disrupting a specific chromatin loop and silencing the tumor suppressor ZBTB20. This event unleashes the pro‐tumorigenic PMEPA1‐p38‐STAT1 signaling axis, promoting cancer progression.

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology

Advanced Science, EarlyView.
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...

From liquid to solid bonding in cohesive granular media

, 2010
We study the transition of a granular packing from liquid to solid bonding in the course of drying. The particles are initially wetted by a liquid brine and the cohesion of the packing is ensured by capillary forces, but the crystallization of the solute

Fabrication of High‐Density Multimodal Neural Probes Based on Heterogeneously Integrated CMOS

Advanced Science, EarlyView.
A chiplet‐based methodology democratizes active neural probe development on standard bulk CMOS services. This yields the first probe combining high‐density electrophysiology (416 electrodes) with calcium imaging (832 photodiodes) and complete on‐chip signal processing across 13 shanks.

Adhesive cements and cementation.

Journal of the California Dental Association, 1993
Luting cements are a critical, but weak, link between fixed prostheses and their supporting tooth structures. Luting cements have relatively poor physical properties compared to bulk restorative filling materials, but they must fulfill an additional series of requirements such as low film thickness.
