Pressure‐Assisted Drug Delivery Using High‐Pressure Balloon Platform Improves Vascular Drug Penetration and Anti‐Restenotic Effects

open access: yesAdvanced Healthcare Materials, EarlyView.
A dual‐layer high‐pressure drug‐coated balloon (HP@DCB) increased balloon‐wall contact and promoted deeper paclitaxel (PTX) penetration than a conventional noncompliant DCB. In in vivo study, HP@DCB treatment improved luminal patency and reduced neointimal hyperplasia, supporting pressure‐assisted drug delivery as a promising strategy for enhancing the

Application of liquid chromatography to the determination of emerging pollutants in environmental samples

open access: yes, 2013
Emerging contaminants are compounds that are not currently covered by existing regulations, that have not been previously studied, and that are thought to be a possible threat to environmental health and safety.

Purification Of The Seven Tetranortriterpenoids In Neem (azadirachta Indica) Seed By Counter-current Chromatography Sequentially Followed By Isocratic Preparative Reversed-phase High-performance Liquid Chromatography.

open access: yes, 2007
Counter-current chromatography (CCC) sequentially followed by isocratic preparative reversed-phase high-performance liquid chromatography was used to isolate the seven bio-actives (azadirachtin A, azadirachtin B, azadirachtin H, desacetylnimbin ...

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

open access: yesAdvanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Determination of trace levels of phenol and cresols in rain by continuous liquid-liquid extraction and high-performance liquid chromatography

open access: yes, 1987
Trace levels of phenol and methylphenols (cresols) in aqueous samples were determined by continuous liquid-liquid extraction and normal-phase high-performance liquid chromatography with UV-fluorescence detection.

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

open access: yesAdvanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

open access: yesAdvanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Gas‐liquid chromatography of hexosamines

open access: yesFEBS Letters, 1971
The analysis of hexosamines is usually performed by calorimetric methods [ 1,2] that do not differentiate between individual amino sugars. It is therefore necessary to separate the hexosamines prior to analysis [3-S] ; this is laborious and requires large quantities of materials. The analysis of carbohydrates, as their trimethylsilyl (TMS) derivatives,

Coordination Bridges in Confined‐Water Domains Enable Partially Desolvated Zn2+ Transport in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
A multifunctional polymer layer with amide and imidazolium groups simultaneously suppresses dendrite growth and hydrogen evolution in Zn‐ion batteries. By providing Zn2+ binding sites and forming a confined‐water domain that acts as a coordination bridge, it boosts single‐ion conductivity and stability, enabling 4000 stable cycles in Zn‐I2 full cells ...
