Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

Advanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Gestalt Theory and Morphology: Linking Points, Lines of Development, and Areas of Focus

Gestalt Theory
Gestalt theory and morphology are concepts of Gestalt psychology that were developed at different times in different places in Germany. Wilhelm Salber’s psychological morphology takes from Gestalt theory its focus on the significance of its questions for

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Use Media Richness Theory and Web Interactivity Theory to Explain Companies Social Media Use

, 2012
[[abstract]]台灣品牌社群的參與率逐漸超越其他網路媒體與企業網站。 多數消費者傾向從社群媒體尋求購買資訊或支持喜好的品牌。 社群媒體提供企業在品牌推廣與緊密顧客關係上的新傳播媒介，有助於增加消費者的忠誠行為與推薦行為。過去研究多針對網路用戶的社群媒體使用行為，探討企業使用行為則多由實務案例整合而來，缺乏整合媒體理論與網路傳播理論觀點的研究。鑑於實務界如火如荼的運用社群媒體，本論文整合媒體豐富理論與網路互動理論提出研究模型，探討企業使用新興媒體的行為，提供學術界與實務界參卓 ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Using Innovation Diffusion Theory to Guide Collaboration Technology Evaluation: Work in Progress

, 2001
Cost effective development of collaboration technology requires evaluation methods that consider group practices and can be used early in a system’s life-cycle. To address this challenge we developed a survey to evaluate collaboration technology based on

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

Advanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.
