Abstract:
... Open-tubular capillary electrochromatography (OT-CEC) is an important tool in separation science due to its effective performance and reusability, and has attracted attention because the coating-process and the coating thickness can be controlled. Although dozens of OT-CEC reviews have been published recently, design of the smart polymer coatings, which can improve the separation efficiency of OT- ...

Abstract:
... Apart from the O releasing at a low rate, large polarization at a high rate is also a big challenge for Li-rich Mn-based oxide (LMO). Prussian blue (PB) with a specific redox potential is regarded as a suitable coating layer to overcome these drawbacks, while its stability is easily destroyed by the intrinsic Jahn–Teller effect after a long run. Herein, Mn vacancy (MV) is introduced into the PB co ...

Abstract:
... Diffusiophoresis is the spontaneous motion of particles under a concentration gradient of solutes. Since the first recognition by Derjaguin and colleagues in 1947 in the form of capillary osmosis, the phenomenon has been broadly investigated theoretically and experimentally. Early studies were mostly theoretical and were largely interested in surface coating applications, which considered the dire ...

Abstract:
... Herein, a novel chiral covalent organic framework, DA-TD COF, with good chemical/thermal stability was synthesized and used as a chiral stationary phase for open-tubular capillary electrochromatography enantioseparation. The DA-TD COF coated capillary exhibited excellent enantioseparation efficiency and its separation efficiency did not show an obvious decrease over 200 runs. Furthermore, the enan ...

Abstract:
... A frame-guided wetting strategy is reported to synthesize highly uniform but asymmetrical colloidal particles from rings to oblate ellipsoids through symmetrical discs, which can self-assemble into diversified highly open 2D superstructures. In particular, ring-shaped particle monolayers have a higher contact angle of water than similar spherical ones, suggesting an attractive particle material fo ...

A novel systematic fabrication approach, called Bi-modal Milling (BiM), is proposed to prepare the austenitic steel (SUS316L) with peculiar Bimodal grain size structure, called Harmonic Structured (HS), with precisely controlled microstructural features of the fine-grained Shell and coarse-grained Core zones. The proposed technique consists of controlled mechanical milling of coarse- and fine-size ...

The accent is on the self-assembling phenomena in aqueous solutions of four-antennary oligoglycines [Glyₙ-NHCH₂]₄C. The newly acquired knowledge regarding the fine-tuning options for the onset, stability, and properties of the ...

The binary blends were composed of nearly symmetric polystyrene-block-poly(methyl methacrylate), PS-b-PMMA, and homo-polystyrenes (PS) of three different molecular weights (hereafter hPS².⁸, hPS⁶, and hPS¹⁷). Films of two initia ...

The economically favored process comprises dip coating engineered support layer fibers to form a dense skin layer in a CMSCMS precursor. The coated fibers are then pyrolyzed to form a high-performance CMS ...

Abstract:
... Organosilane, with functional organic groups attached to inorganic silicon atoms, exhibits excellent passivation performance for pyrite. However, a considerable number of micro-cracks will gradually appear on the surface of passivation film under long-term corrosion of oxidizing medium, resulting in a significant decrease of passivation effect. To improve the stability and long-term performance of ...

However, poor toughness of the ZrB₂ coating is an important problem to be solved urgently. This study designed and prepared ZrO₂–B₄C–Al precursor and nano-ZrB₂-based composite coating were prepared in situ by reactive plasma spraying. The obtained toughness values of coating by ...

Abstract:
... Bismuth has been proved a promising lead-free element that can mitigate whisker growth on Sn coatings. It is generally believed that the formation of the equiaxed crystal structure of Sn–Bi coating helps to relax the compressive stress uniformly. In this study, the Sn–xBi coatings with the columnar structure were prepared on the Al substrate. The addition of Bi promoted the whisker nucleation on t ...

... A passivated Au/α-MoC catalyst, containing 2–4 layered Au clusters of 1.6 nm, was re-activated by CH₄/H₂ at 590 °C, during which the structure of the gold-carbide interface changed considerably. The partially-oxidized surface Mo species were carburized to MoC, while the Au clusters dispersed into smaller ones, accompanied by the coating of carbide thin layers on Au. This restructuring promoted cha ...

... Small-area metal–halide perovskite solar cells (PSCs) having power-conversion efficiencies (PCEs) of greater than 25% can be prepared by using a spin-coated perovskite layer, but this technique is not readily transferrable to large-scale manufacturing. Drop-casting is a simple alternative method for film formation that is more closely aligned to industry-relevant coating processes. In the present ...

Utilizing different phosphorescent materials as emitter guests, this work investigates the root causes of the lower electroluminescence (EL) stability of solution-coated (SOL) organic light-emitting devices (OLEDs) relative to their vacuum-deposited (VAC) counterparts. The results show that emitter guest molecules aggregate under electrical stress, leading to the emergence of new longer-wavelength ...
