Abstract Perylene-based organic semiconductors are attractive photoactive materials due to their broad visible-light absorption, large extinction coefficients, high photostability, and relatively low cost. However, the fabrication of perylene-based organic thin films often suffers from complicated and tedious procedur…
Abstract Photochemical control of the hardness and fluidity of polymeric materials is applicable to the development of photoreversible adhesives. Here, we report that common polymers show photoplasticization behavior, which is the photoinduced reduction of the glass transition temperature, just by adding an azobenzene…
A hierarchical superhydrophobic surface is prepared via a two-step boiling water immersion process and anodization of the treated aluminum substrate in a novel hydrophobic electrolyte of aluminum nitrate and stearic acid mixture at room temperature. The immersion time in boiling water had a significant influence on th…
On-demand switchable “additive/subtractive” patterning of two-dimensional (2D) nanomaterials is an essential capability for developing new concepts of functional nanomaterials and their device realizations. Traditionally, this is performed via a multistep process using photoresist coating and patterning by conventiona…

Abstract Semiconducting 2D materials, such as SnS2, hold great promise in a variety of applications including electronics, optoelectronics, and catalysis. However, their use is hindered by the scarcity of deposition methods offering necessary levels of thickness control and large‐area uniformity. Herein, a low‐tempera…
Cotton fibres have been used in many absorbent products. A porous structure is most conducive to absorbing liquid. More is the porosity better would be the absorbent capacity. However, a porous fibrous structure is structurally fragile and can easily collapse during the absorbing process leading to changes in porosity…
Hydrogen is considered an ideal energy carrier. However, the use of fossil fuels to produce hydrogen depletes natural resources and causes environmental problems. Therefore, there is an urgent need to find alternative raw materials and technologies for the production of hydrogen. Waste cooking oil (WCO) is a renewable…
Hydrogen is yet to be widely accepted as a fuel for everyday operation due to stringent safety regulations involved around it. In the meanwhile, methanol could be a potential fuel of the future. In this work, an extensive thermodynamic investigation on an energy storage system with a reversible solid oxide stack at it…
Abstract Polyelectrolyte multilayers are usually prepared from polydisperse polyelectrolytes. It is desirable to measure and control multilayer composition when it deviates from the deposition solution. With neutron reflectivity, multilayers prepared from PDADMA and binary mixtures of long deuterated PSSdlong (80.8 kD…
In this work, cerium-doped LaF3 nanoparticles (Ce NPs) were successfully synthesized and characterized. Its chemiluminescence (CL) property was studied and amazedly found that it intensely enhanced the ultraweak CL of NaNO2-H2O2 system. The CL mechanism was systematically investigated and suggested to be the recombina…
OBJECTIVE: Glioma stem cells (GSCs) are responsible for tumor initiation, therapeutic resistance, and recurrence. CD146 is mainly expressed in dividing GSCs and regulates cell cycle progression. However, the evaluation of the efficacy of targeted therapy against CD146 in vivo remains to be investigated. In this study,…
This study explored the impact of gold nanoparticles on the metabolic activity and morphology of human pulmonary endothelial cell monolayers. We developed a gold nanoparticle library of three different sizes and two surface chemistries that include anionic citrate and the cationic polyelectrolyte poly(allylamine hydro…
Aggregation-induced emission (AIE) behavior of water-soluble tetraphenylethene (TPE) derivatives bearing carboxy and sulfo groups was studied at polarized liquid|liquid interfaces. The aggregation behavior of TPE derivatives in solution and at the water|1,2-dichloroethane (DCE) interface was highly dependent on their…
Electron spin resonance (ESR) thermochronometry can in principle be used for reconstructing thermal histories of the upper ~ 2 km of the Earth's crust . We have analysed the ESR ages of Al and Ti centres in quartz from Fergusons Hill-1 borehole in the Otway Basin, Australia, to assess their trap parameters under natur…
Dealloying typically occurs via the chemical dissolution of an alloy component through a corrosion process. In contrast, here we report an atomic-scale nonchemical dealloying process that results in the clustering of solute atoms. We show that the disparity in the adatom-substrate exchange barriers separate Cu adatoms…
OBJECTIVES: Gadolinium deposition is widely believed to occur, but questions regarding accumulation pattern and permanence remain. We conducted a retrospective study of intracranial signal changes on monthly triple-dose contrast-enhanced magnetic resonance imaging (MRI) examinations from the previously published Betas…
Abstract Advanced polycrystalline ceramics are gaining importance on development of light‐emitting diodes, infrared detectors, solid‐state lasers, etc. The physical properties of these materials are dependent on variety of dopant concentrations. In this manuscript, we have synthesized Yb‐doped Y 2 O 3 (Y 2‐x Yb x O 3…
Abstract The shrinkage of an oxygen single‐bubble is investigated in a cerium‐doped borosilicate glass melt at 1150°C. Nine glass samples are synthesized and investigated, utilizing three different amounts of Ce 2 O 3 and three different redox ratios (Ce‐(III)/Ce total ). Employing in‐situ observation, the single‐bubb…
Nanodiamonds have outstanding mechanical properties, chemical inertness, and biocompatibility, which give them potential in various applications. Current methods for preparing nanodiamonds often lead to products with impurities and uneven morphologies. We report a two-step high-pressure high-temperature (HPHT) method…
