MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Microstructure and properties of ductile iron bars for plunger pump prepared by horizontal continuous casting process [PDF]

China Foundry, 2019
Ductile iron bars (DIBs) with a diameter of 145 mm, used for plunger pump production, were made by the horizontal continuous casting (HCC). The microstructure of the samples cut at three locations with different distances away from the surface (~20 mm ...

Nitric oxide synthase enzymology in the 20 years after the Nobel Prize

British Journal of Pharmacology, 2018
This review briefly summarizes what was known about NOS enzymology at the time of the Nobel Prize award in 1998 and then discusses from the author's perspective some of the advances in NOS enzymology over the subsequent 20 years, focused on five aspects:

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Novel Functional Materials via 3D Printing by Vat Photopolymerization

Advanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Perspective: OLED Displays Singing with the Blues

Advanced Materials, EarlyView.
While blue pixels consume approximately 50% of the energy of OLED display front planes, in the 25 years since their invention, 100% internal efficiency triplet‐controlled phosphorescent OLEDs have not met the stability standards necessary for their adoption.

Microcapsule‐Mediated Vibration‐Induced Emission for Real‐Time Visualization of Polymer Deformation

Advanced Optical Materials, EarlyView.
A mechanochromic microcapsule is reported that combines vibration‐induced luminescence (VIE) with mechanically controlled release functionality. By embedding the microcapsules into a polymer matrix, the conformational changes of VIE molecules can be precisely amplified into visual fluorescent color signals, enabling real‐time, high‐sensitivity ...
