Body of Knowledge: Renaissance Armor and the Engineering of Mind = Cuerpos del conocimiento: armaduras del Renacimiento y la ingeniería de la mente

open access: yesEspacio, Tiempo y Forma. Serie VII, Historia del Arte, 2018
This essay charts the role of armor in Renaissance practices of knowledge. Since the advent of gunpowder warfare, armor was largely unfit for combat, yet still became a centerpiece of princely representation and was prominently displayed in early ...

Synchronized Electro‐Chromo‐Emissive Devices Using a Mixed Ionic‐Electronic Conductive Layer for XR Applications

open access: yesAdvanced Functional Materials, EarlyView.
A single cell type Electro‐chromo‐emissive (ECECL) device integrating synchronized electrochromic (EC) and electrochemiluminescent (ECL) functions is developed using a mixed ionic‐electronic conductor (MIEC). A MIEC layer reduces ionic/electronic resistance, enabling ultrafast switching and enhanced optical contrast.

Atomic‐Level Dual‐Cation Engineering Enables High‐Performance Na4VMn(PO4)3 Cathodes for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Dual‐cation site engineering unlocks stable and fast sodium storage in Na4VMn(PO4)3 cathodes. Li+ at Na2 suppresses Jahn‐Teller distortion, while K+ at Na1 expands ion channels, enabling synchronized V/Mn redox and quasi‐single‐phase kinetics. This atomic‐level strategy achieves ultralong cycling stability, high‐rate capability, and full cell viability

PTFE‐Activated Graphene Overcomes Dispersion Challenges for Scalable Solvent‐Free Fabrication of Ultra‐Thick, High‐Performance Cathodes in Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
PTFE nanoparticle–anchored rGO (rGO@PTFE) for scalable solvent‐free fabrication of ultra‐thick, high‐density cathodes, achieving high conductivity (9.55 S cm−1), lithium transference (0.73), and improved wettability, is developed. The resulting cathode delivers 15.2 mAh cm−2 areal and 563 mAh cm−3 volumetric capacities, with full cells exhibiting 637 ...

Artificial Amorphous Interface Matters for Boosting High‐Voltage Stable LiCoO2 Cathode

open access: yesAdvanced Functional Materials, EarlyView.
The amorphization of phosphate‐based surface layer with favorable Li‐ion conducting kinetics is realized by precisely tailored atomic‐level fabrication. This amorphous coating enables the lithium cobalt oxide (LCO) cathode superior high‐voltage rate capability and cycling performance, owing to the fast interfacial ionic transport and maintained ...

Microprocessor Activity Controls Differential miRNA Biogenesis In Vivo

open access: yesCell Reports, 2014
In miRNA biogenesis, pri-miRNA transcripts are converted into pre-miRNA hairpins. The in vivo properties of this process remain enigmatic. Here, we determine in vivo transcriptome-wide pri-miRNA processing using next-generation sequencing of chromatin ...
