In this report, we present a synthetic method for the formation of cuprous sulfide (Cu2S) and lead sulfide (PbS) nanomaterials directly on substrates from the thermolysis of single-source precursors. We find that the final morphology and arrangement of the nanomaterials may be controlled through the concentration of t…
A novel (3,4)-connected 3D self-penetrating metal-organic framework with a nanometre-scale cavity constructed from metallacalix[4]arene building blocks and Keggin-type polyanions has been obtained by using a 1,3-bis(1-methyl-5-mercapto-1,2,3,4-tetrazole)propane ligand.
For the first time, we provide evidence for both heterogeneous nucleation at the mesoscopic scale and the progression of the non-classical crystallization process during the microwave synthesis of cupric oxide (CuO) with sea urchin-like morphology. This work sheds light on the general mechanism of the growth of CuO ar…
Predicting the ability of low molecular weight molecules to form hydrogels is difficult. Here, we have examined the self-assembly behavior of two chemically and structurally similar functionalized dipeptides, one of which is found to form a meta-stable hydrogel (1) and the other forming a crystalline solid (2). To inv…
We report the synthesis of composite RuO(2)/poly(3,4-ethylenedioxythiophene) (PEDOT) nanotubes with high specific capacitance and fast charging/discharging capability as well as their potential application as electrode materials for a high-energy and high-power supercapacitor. RuO(2)/PEDOT nanotubes were synthesized i…
The unique properties of graphene and carbon nanotubes made them the most promising nanomaterials attracting enormous attention, due to the prospects for applications in various nanodevices, from nanoelectronics to sensors and energy conversion devices. Here we report on a novel deterministic, single-step approach to…
In this study, we report a simple method to coat mesoporous silica onto carbon nanotubes (CNTs) via a two-step procedure. Mesoporous CNTs@SiO2 composites have been obtained by extracting cetyltrimethylammonium bromide (CTAB) via an ion-exchange procedure after silica-coated carbon nanotubes were synthesized with the a…
Recently, ionic liquids have been studied as promising solvents for cellulose. Since ionic liquids can be combined freely from different cations and anions, possible candidates are numerous. Therefore, a time efficient method to screen ionic liquids with respect to their solvent power is mandatory to find an optimal c…
The main methods applied to clean plant material for radiocarbon dating are not compound-specific and generally remove only the easily exchangeable components by an acid-base-acid sequence and additional optional steps like Soxhlet extraction to remove resins and oxidative bleaching with NaClO 2 . The products are nor…
An alkaline phosphatase activity detection system was constructed based on the different quenching effect of the enzyme substrate and product on the β-CD-functionalized CdTe QDs.
In this report, we demonstrate the synthesis of binary sulfide Ag–In–S NPs using a Ag–In thiolate complex. Thermal decomposition of the thiolate complex provides Ag/AgInS2 heterostructured nanoparticles (NPs). A metathesis reaction between the thiolate complex and sulfur source leads to the formation of nearly monodis…
pH-responsive surfaces, reversibly switching between superhydrophilicity and superhydrophobicity/water repellency, are developed by "grafting from" a pH-sensitive polymer onto a hierarchically micro/nano-structured substrate. We quantify the water repellency by investigating the restitution coefficient of water drople…
Layered double hydroxides (LDHs) films with hierarchical morphologies have been fabricated on different templates via the sol-gel nanocopying and in situ growth process, which exhibit desirable mechanical properties and high adaptability in water treatment.
We attempt to elucidate the dynamics of multiarm star polymer solutions, which are representative of a large class of soft hairy colloids, over a wide range of concentrations. In addition to the usual β-relaxation (in-cage rattling) and α-relaxation (terminal cage escape), the relaxation of stars in the glassy state i…
In the last five years, several excellent reviews about oriented attachment (OA) have evidenced the advances achieved in this research area, detailing the growth mechanism and the kinetic models. The main focus of this review is to examine the dependence of the OA mechanism on the colloidal state and to demonstrate ho…
Microporous polyimide networks with BET surface areas up to 1407 m(2) g(-1) and pore size distribution of 4-8 Å were synthesized. The respective effect of surface area and affinity between hydrogen molecule and polyimides on hydrogen storage properties were investigated.
Woven and nonwoven flax fiber reinforced poly lactic acid (PLA) biocomposites were prepared with amphiphilic additives as accelerator for biodegradation. The prepared composites were buried in farmland soil for biodegradability studies. Loss in weight of the biodegraded composite samples was determined at different ti…
The application of a LaGaO3 based electrolyte for steam electrolysis was studied and it was found that the H2 formation rate obeys the Faraday's law suggesting unity of oxide ion conductivity in LaGaO3 perovskite oxide under an electrolysis condition up to 2.0 V applied potential. Among the examined metal catalysts, n…

The field of shape memory polymers (SMPs) has been dominated by polymeric network systems whose fixing mechanism is based on crystallization or vitrification of the constituent chains, rendering such systems stiff in comparison to elastomers, gels, and living tissues. In this report, we describe the synthesis and char…
