Multi-Layered Branched Surface Fluorination on PVDF Membrane for Anti-Scaling Membrane Distillation.

Membrane distillation (MD) has emerged as a promising technology for hypersaline wastewater treatment. However, membrane scaling is still a critical issue for common hydrophobic MD membranes. Herein, we report a multi-layered surface modification strategy on the commercial polyvinylidene fluoride (PVDF) membrane via plasma treatment and surface fluorination cycles.

Improved Efficiency and Stability of Red Phosphorescent Organic Light-Emitting Diodes via Selective Deuteration.

The secondary kinetic isotope effects (KIEs) of red phosphorescent Ir(III) complexes and the corresponding devices have been investigated. The selective deuterated red emitters show negligible influence on the luminescent spectra, but have positive effects on the quantum efficiencies and stabilities in the devices. As secondary KIEs predicted, the photolysis coinciding with the electrolysis of the deuterated complexes in the devices, measured via decreasing of luminescent intensity, are reduced in rate.

Clinical impact of Fn-induced high expression of KIR2DL1 in CD8 T lymphocytes in oesophageal squamous cell carcinoma.

Background: To analyze the correlation between the inducing effect of (Fn) on the surface expression of the inhibitory receptor KIR2DL1 on CD8 T cells in oesophageal squamous cell carcinoma (ESCC) and the clinicopathological features and survival prognosis and to explore its clinical significance.

Methods: The inducing effect of Fn on CD8 T cell surface inhibitory receptor KIR2DL1 expression was analyzed in a coculture system of human CD8 T cells and ESCC cells infected with Fn. Fn infection and the expression of KIR2DL1 on CD8 T cells were detected by RNAscope and immunohistochemistry in ESCC tissues, and the correlations between the inducing effect of Fn on KIR2DL1 expression on CD8 T cells and clinicopathological features were analyzed.

Low-Threshold Amplified Spontaneous Emission from Air-Stable CsPbBr Perovskite Films Containing Trace Amounts of Polyethylene Oxide.

Organic additives can enhance the amplified spontaneous emission (ASE) performance of inorganic cesium lead halide perovskites (CsPbBr ) but volatility, potential hygroscopicity and oxidative degradation of these additives jeopardizes the thermal stability and shelf-life of blended CsPbBr films. To address this problem, we have fabricated perovskite films in a two-step solution protocol involving as little added polyethylene oxide (PEO) as possible. These films exhibited enhanced crystallization, improved photoluminescence (PL) intensity and prolonged lifetimes.

Structural modulation induced by cobalt-based ionic liquids for enhanced thermoelectric transport in PEDOT:PSS.

Poly(3,4ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) has been intensively studied for its thermoelectric applications. Structural modulation to improve crystalline ordering, chain conformation and film morphology is a promising way to decouple the trade-off between conductivity and Seebeck coefficient and thus improve the thermoelectric power factor. Post treatment with ionic liquid ([CoCl  ⋅ 6H O]:[ChCl]) bearing cobalt-containing anions resulted in a remarkable enhancement of the power factor to 76.

Coordination polymers for n-type thermoelectric applications.

Coordination polymers (CPs) are potential thermoelectric (TE) materials to replace the sometimes costly, brittle and toxic heavy metal inorganic TEs for near-ambient-temperature applications. Air-stable and highly conductive p-type thermoelectric CPs are relatively well known, but the their n-type counterparts are only now emerging and both are needed for most practical applications. This perspective reviews recent advances in the development of n-type thermoelectric CPs, particularly the 1D and 2D metal bisdithiolenes, and introduces a relatively new class of guest@metal-organic framework(MOF)-based composites.
