Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

open access: yesAdvanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Dimensionality dependence of optical nonlinearity and relaxation dynamics in cuprates

open access: yes, 2001
Femtosecond pump-probe measurements find pronounced dimensionality dependence of the optical nonlinearity in cuprates. Although the coherent two-photon absorption (TPA) and linear absorption bands nearly overlap in both quasi-one and two-dimensional (1D ...

Two-photon-absorption-based OSNR monitor for NRZ-PSK transmission systems [PDF]

open access: yes, 2010
A two-photon absorption microcavity-based technique for monitoring in-band optical signal-to-noise ratio (OSNR) in nonreturn-to-zero phase-shift-keying systems is presented.

Plasma‐Polymerized Nanoparticles Presenting Fibrillin‐1 Drive Rapid Re‐Endothelialization of Vascular Grafts

open access: yesAdvanced Healthcare Materials, EarlyView.
Commercial vascular grafts are made from ePTFE, a highly hydrophobic, foreign material that fails at a high rate in small‐diameter applications. Plasma polymer nanoparticles (PPN) are a versatile material functionalisation tool, used here to present fibrillin‐1 fragment PF8 on the graft surface.

Ageing and amyloid-beta peptide deposition contribute to an impaired brain tissue plasminogen activator activity by different mechanisms

open access: yesNeurobiology of Disease, 2007
Alzheimer’s disease (AD) is the most common form of neurodegenerative disorder in the ageing population. It is characterized by the cerebral accumulation of toxic amyloid-beta peptide assemblies (Aβ).

Influence of cavity lifetime on high-finesse microcavity two-photon absorption photodetectors [PDF]

open access: yes, 2007
For optical pulse incidence as compared with continuous-wave incidence, the enhancement of two-photon absorption inside a high-finesse planar microcavity is reduced, the pulse inside the cavity and the cavity spectrum are broadened.

Progesterone Attenuates Hemorrhagic Transformation after Delayed tPA Treatment in an Experimental Model of Stroke in Rats: Involvement of the VEGF–MMP Pathway

open access: yesJournal of Cerebral Blood Flow and Metabolism, 2014
Tissue plasminogen activator (tPA) is the only FDA-approved treatment for acute stroke, but its use remains limited. Progesterone (PROG) has shown neuroprotection in ischemia, but before clinical testing, we must determine how it affects hemorrhagic ...

Crystal Engineering of Reticular Materials for Gas‐ and Liquid‐Phase Hydrocarbon Separation

open access: yesAdvanced Materials, EarlyView.
Crystal engineering enables systematic study of structure/function relationships as exemplified by pore engineering of reticular sorbents, including porous coordination networks and covalent organic frameworks. This review assesses such studies applied across the full scope of industrially relevant hydrocarbon separations to provide insight into how ...

The Influence of Fluorination on Nano-Scale Phase Separation and Photovoltaic Performance of Small Molecular/PC71BM Blends

open access: yesNanomaterials, 2016
To investigate the fluorination influence on the photovoltaic performance of small molecular based organic solar cells (OSCs), six small molecules based on 2,1,3-benzothiadiazole (BT), and diketopyrrolopyrrole (DPP) as core and fluorinated phenyl (DFP ...

Tumor promoter TPA activates Wnt/β-catenin signaling in a casein kinase 1-dependent manner. [PDF]

open access: yes, 2018
The tumor promoter 12-O-tetra-decanoylphorbol-13-acetate (TPA) has been defined by its ability to promote tumorigenesis on carcinogen-initiated mouse skin.
