Colloidal Crack Sintering Lithography for Light‐Induced Patterning of Particle Assemblies

open access: yesAdvanced Functional Materials, EarlyView.
Colloidal crack sintering lithography (CCSL) is a microfabrication technique that uses light‐induced photothermal heating to trigger sintering and controlled cracking in polymer colloidal assemblies. Local structural changes generate microchannels and patterns, enabling direct writing of diverse topographic motifs.

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

open access: yesAdvanced Functional Materials, EarlyView.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

Multimodal Structural Color Graphics Based on Colloidal Photonic Microdome Arrays

open access: yesAdvanced Functional Materials, EarlyView.
A hybrid photonic system combining colloidal crystals and microscale domes is designed to achieve four switchable optical states via the interplay of Bragg reflection and TIR interference. The graphics composed of the photonic microdome arrays provide tunable, angle‐sensitive structural coloration and concealed‐to‐revealed transitions, offering a ...

Government Policies toward Information and Communication [PDF]

open access: yes
The development of what one might call 'modern' systems of information and communication began with the Gutenberg printing press in the 15th century, and progressed through the prepaid postal system, electric telegraph and telephone in the 19th century ...

A Survey of Perceived Job satisfaction Among School Nurses [PDF]

open access: yes, 2006
Many studies have examined job satisfaction of nurses in various clinical settings, but few have focused on school nurses. This project was a follow-up to the study by Foley, Wilson, Lee, Young Cureton, & Canham (2004), who used a written questionnaire ...

Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Speculative trading: the price multiplier effect

open access: yes, 1999
During a speculative episode the price of an item jumps from an initial level p_1 to a peak level p_2 before more or less returning to level p_1. The ratio p_2/p_1 is referred to as the amplitude A of the peak.
