Triple-responsive inorganic–organic hybrid microcapsules as a biocompatible smart platform for the delivery of small molecules
nanostructures which were in situ deposited into the polymer shell of microcapsules during sol-gel synthesis. This results in the formation of a composite hybrid shell with enhanced mechanical stability. Such sol-gel modification reduces the permeability of the capsule shell to allow for small molecule encapsulation.…
Luminescent Cu I thiocyanate complexes based on tris(2-pyridyl)phosphine and its oxide: from mono-, di- and trinuclear species to coordination polymers
The synthesis, structural and photophysical properties of the novel family of Cu( i ) thiocyanate complexes supported by tripodal ligands are presented.
Spin-state diversity in a series of Co( ii ) PNP pincer bromide complexes
We describe the structural and electronic impacts of modifying the bridging atom in a family of Co( ii ) pincer complexes with the formula Co( t -Bu) 2 P E Py E P( t -Bu) 2 Br 2 (Py = pyridine, E = CH 2 , NH, and O for compounds 1–3 , respectively).
Epitaxial growth of two-dimensional SnSe 2 /MoS 2 misfit heterostructures
van der Waals (vdWs) heterostructures, obtained by vertically stacking two-dimensional layered materials upon each other, appear particularly promising for future atomically thin electronic and optoelectronic devices and attract a great deal of attention due to their diverse functionalities.
Biosynthesis of silver nanoparticles using lavender leaf and their applications for catalytic, sensing, and antioxidant activities
Abstract The present report summarizes an eco-friendly approach for the biosynthesis of silver nanoparticles (AgNPs) using the leaf extract of lavender. Initially, the synthesis of AgNPs was visually observed by the appearance of a wine red color. The optical property, morphology, and structure of as-synthesized AgNPs…
Conjugated microporous polymer networks with adjustable microstructures for high CO 2 uptake capacity and selectivity
A series of phenylene-based conjugated microporous polymers (CMPs) of the A 6 + M x ( x = 2, 3, 4, 6) type were synthesized.
Point defects in lines in single crystalline phosphorene: directional migration and tunable band gaps
Extended line defects in two-dimensional (2D) materials can play an important role in modulating their electronic properties. During the experimental synthesis of 2D materials, line defects are commonly generated at grain boundaries between domains of different orientations. In this work, twelve types of line-defect s…
Design and synthesis of micro–meso–macroporous polymers with versatile active sites and excellent activities in the production of biofuels and fine chemicals
Micro–meso–macroporous polymers with versatile active sites were synthesized by hyper-cross-linking technology, which exhibit excellent activities for catalyzing production of biofuels and fine chemicals.
The surface tells it all: relationship between volume and surface fraction of liquid dispersions
The properties of liquid dispersions, such as foams or emulsions, depend strongly on the volume fraction ϕ of the continuous phase. Concentrating on the example of foams, we show experimentally and theoretically that ϕ may be related to the fraction ϕs of the surface at a wall which is wetted by the continuous phase –…
Cefuroxime derived copper nanoparticles and their application as a colorimetric sensor for trace level detection of picric acid
Picric acid is used as explosive material in destructive weapons and nuclear technology. Due to higher solubility in water it can create health issues and its monitoring is crucial for safer environment and health.
Effect of Al Composition on the Corrosion Resistance of Mg-14 mass% Li System Alloy
Mg-Li system alloys have poor corrosion properties, especially cold-rolled sheet leads to exfoliation corrosion as a result of long-term immersion test. Addition of aluminum element to Mg-14 mass% Li alloy could be suppressed the occurrence of exfoliation corrosion. However, excess addition of aluminum to Mg-14 mass%…
TM@gt-C 3 N 3 monolayers: high-temperature ferromagnetism and high anisotropy
High temperature ferromagnetic materials with planar surfaces are promising for spintronics applications.
“Smart poisoning” of Co/SiO 2 catalysts by sulfidation for chirality-selective synthesis of (9,8) single-walled carbon nanotubes
The chirality-selective synthesis of relatively large (diameter > 1 nm) single-walled carbon nanotubes (SWCNTs) is of great interest for a variety of practical applications, but only a few catalysts are available so far. Previous studies suggested that S (compounds) can enhance the chirality-selectivity of Co catalyst…
Insight into the mechanism about the initiation, growth and termination of the C–C chain in syngas conversion on the Co(0001) surface: a theoretical study
CH with hydrocarbons will depend strongly on the hydrogen coverage on the metal surface. The results of this work not only illustrate the initiation, growth and termination mechanism of the C-C chain involved in FTS on the Co(0001) surface, but also serve as a basis for the rational design of other Co surfaces toward…
