Programming Defects and Cavities into Colloidal Crystals Engineered With DNA

open access: yesAdvanced Materials, EarlyView.
Seed‐mediated crystallization is adapted for colloidal crystals to design cavities and defect architectures through chemically programmed DNA sequences and appropriate seed particle geometry. This synthetic approach combines tenets from both atomic and colloidal crystallization to deliberately control defect formation in superlattices and enables the ...

Photothermally Powered 3D Microgels Mechanically Regulate Mesenchymal Stem Cells Under Anisotropic Force

open access: yesAdvanced Materials, EarlyView.
The photothermally powered microgel is designed to mechanically train mesenchymal stem cells using spatially patterned exogenous forces in three‐dimensional (3D) workspaces. When microgels are activated selectively via photothermal actuation, locally confined tens of nN forces are exerted on cells, triggering osteogenic differentiation in encapsulated ...

Magnetically “Programming” Cobalt‐Doped Iron Oxide Nanoparticles for Localized Induction Heating: Triggering a Collective Effect of Magnetic Moment Alignment on Demand

open access: yesAdvanced Materials, EarlyView.
This study demonstrates enhanced induction heating in cobalt‐doped iron oxide nanoparticles via specific pre‐magnetization, induced by the pre‐alignment of magnetic moments. By correlating Co content with magnetic properties, the research highlights how magnetic pre‐programming enables localized, on‐demand debonding in composites.

Stylistics and Persuasion

open access: yesStylistyka, 2008
The paper deals with stylistics and persuasion but, in order to be able to speak about them, we started first with the presentation of rhetoric that represents the core for both the study of style and the study of argumentation. Stylistics and persuasion

Imagining the Behavioural Scenarios in the Discourse of Publicity Bank Brochures- a Persuasion Mechanism

open access: yesEIRP Proceedings, 2020
Our research aims at arguing that the presence of behavioural scenarios in the discourse of publicity bank brochures can be validated in a mechanism of persuasion.

Dual Vacancy Engineering in Alloyed Ga‐Zn‐Cu‐Se Quantum Dots for Photocatalytic 5‐Hydroxymethylfurfural to 2,5‐Diformylfuran Conversion

open access: yesAdvanced Materials, EarlyView.
A dual‐vacancy‐engineered strategy is developed to construct Ga‐Zn co‐doped CuSe quantum dots (GZC QDs) via cation exchange using CuSe as a template. By precisely introducing Cu and Se vacancies, the optimized sample efficiently facilitates the selective photocatalytic oxidation of 5‐hydroxymethylfurfural (HMF) to 2,5‐diformylfuran (DFF), achieving an ...
