Phthalocyanine covalent organic frameworks with different central metals are synthesized, and the AA-stacking structure of the 2D polymer sheets results in periodic phthalocyanine π-columns. The central metals control the π-electronic functions, including the improvement of light absorbance, the ease of carrier transp…
The current fabrication methods of pristine graphene are not feasible for bulk production. The closest approach, which is through chemical reduction of graphene oxide to chemically reduced graphene oxide that resembles pristine graphene, has been widely adopted instead. Herein, we report a new methodology for the redu…
Inspired by the promising thermoelectric properties in the Zintl compounds Ca3AlSb3 and Ca5Al2Sb6, we investigate here the closely related compound Sr3GaSb3. Although the crystal structure of Sr3GaSb3 contains infinite chains of corner-linked tetrahedra, in common with Ca3AlSb3 and Ca5Al2Sb6, it has twice as many atom…
Pebbles is a user-friendly software program which implements an accurate, unbiased, and fast method to measure the morphology of a population of nanoparticles (NPs) from TEM micrographs. The morphological parameters of the projected NP shape are obtained by fitting intensity models to the TEM micrograph. Pebbles can b…
A novel blue-emitting phosphor, Ca5.45Li3.55(SiO4)3O0.45F1.55:Ce3+, was synthesized by a solid-state reaction, and the phase formation, crystal structure and luminescence properties were investigated in detail. The Ca5.45Li3.55(SiO4)3O0.45F1.55:Ce3+ phosphor shows a highly intense blue emission peaking at about 470 nm…
Programmed molecular assemblies with molecular-level precision have always intrigued mankind in the quest to master the art of molecular engineering. In this regard, our review seeks to highlight the state of the art in supramolecular engineering. Herein we describe two-dimensional (2D) nanoarchitectonics of organic a…
Fluorescent polymeric assemblies and nanoparticles (NPs) of nanoscale dimensions have become a focus of intensive investigations during the past few decades due to combined advantages such as improved biocompatibility, water dispersibility, stimuli-responsiveness, facile integration into optical detection devices, and…
In this review article, we present the features and properties of 9,10-di(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene (exTTF) in molecular electronics. Due to its strong donor character accompanied by a geometrical conformational change upon the formation of the oxidized di-cation species, exTTF has found remarkable…
Recently, a novel colloidal hard-rod-like model system was developed which consists of silica rods [Kuijk et al., JACS, 2011, 133, 2346]. Here, we present a study of the phase behavior of these rods, for aspect ratios ranging from 3.7 to 8.0. By combining real-space confocal laser scanning microscopy with small angle…
Herein, we report new nanocomposite materials based on poly(p-phenylenediamine) (PpPD) and hydrogen exfoliated graphene (HEG) sheets as efficient binder-free electrode materials for supercapacitors. The nanocomposites are synthesized via chemical oxidative polymerization of a para-phenyldiamine monomer in the presence…
Here we demonstrate a facile synthesis of 3D mesoporous carbon nitride with Ia3d symmetry (MCN-6) using mesoporous silica KIT-6 with 3D porous structure and different pore diameters as hard templates, and ethylenediamine and carbon tetrachloride as the sources for N and C, and C, respectively. The obtained materials p…
Graphene supported Pd@Co core–shell nanocatalysts with magnetically recyclability were synthesized via the in situ synthesis strategy utilizing the distinction in reduction potentials of the two precursors with appropriate reductant. The as-synthesized catalysts exerted satisfied catalytic activity (916 L mol−1 min−1)…
A simple method has been implemented to prepare a stable and effective redox-active alkaline electrolyte by doping m-phenylenediamine into a conventional KOH electrolyte for a carbon-based supercapacitor. The quick electron transfer and reversible Faradic process in the new electrolyte system results in additional pse…
Here, we report the fabrication of self-organized titania (TiO(2)) nanotube array supercapacitor electrodes through controlled phase transformation of TiO(2), with aerial capacitances as high as 2.6 mF cm(-2), which far exceeds the values so far reported in the literature. The role of phase transformation in the elect…
Noble gold nanoparticles (AuNps) are generally nontoxic due to their inert nature. The gold nanoparticles are easily tagged with various proteins and biomolecules rich in aminoacid leading to important biomedical applications including targeted drug delivery, cellular imaging, and biosensing. In this study, three cyto…
Image guided technique is playing an increasingly important role in the investigation of the biodistribution and pharmacokinetics of drugs or drug delivery systems in various diseases, especially cancers. Besides anatomical imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI), molecula…
Different techniques for encapsulating self-healing materials (liquid monomers) inside polymer fibers [polyacrylonitrile (PAN)] and amorphous turbostratic carbon nanotubes (CNTs) were explored. Two types of healing materials were used: dicyclopentadiene (DCPD) and isophorone diisocyanate. To encapsulate the self-heali…
This tutorial review highlights the methods for the preparation of metal modified precursor derived ceramics (PDCs) and concentrates on the rare non-oxide systems enhanced with late transition metals. In addition to the main synthetic strategies for modified SiC and SiCN ceramics, an overview of the morphologies, stru…
In this paper, fluorescent and magnetic bi-functional NaLuF4:Ln (Ln = Gd3+, Yb3+, Tm3+) nanocrystals were synthesized via a simple hydrothermal method using oleic acid as capping ligand. The crystal phase, size, upconversion (UC) properties, and magnetization of the nanocrystals can be readily modified by doping with…
