This article reviews the general characterization of nano-objects, especially engineered nanoparticles (ENPs) and discusses analytical techniques commonly used for their determination. The main aspect of this review covers the use of the inductively coupled plasma (ICP) technique for the determination of ENPs itself o…
Symmetric oligothiophene derivatives containing hydrogen bond forming segments create self-supporting organogels consisting of self-assembled 1D nanostructures at low concentrations. Hydrogen bond formation and π-π stacking were both found to be crucial for the formation of conductive supramolecular networks of 1D nan…
Nickel cobalt (Ni-Co) oxides with various Ni/Co ratios are synthesized by using a sol-gel process. Electrochemical performance, microstructure, morphology and BET surface area are found strongly related to Ni and Co concentration. Increasing Co concentration changes the oxide microstructure from NiO crystal dominate s…
The different methods for modification of carbon nanotubes with dendrimers or hyperbranched polymers are summarized, and recent development is highlighted by discussing some representative examples in detail.
We report formation of nano-to-microscale satellite droplets in the geometrical shadow of high contact angle primary drops during dropwise water condensation on a nanostructured superhydrophobic surface (SHS). The primary drops contribute to the heat transfer process by sweeping up satellite droplets without covering…
Despite the superior bulk protonic conductivity combined with chemical stability in the temperature region in which intermediate-temperature solid oxide fuel cells (IT-SOFCs) are operated, the use of polycrystalline ceramics of yttrium-doped barium zirconates (BZY) as a solid electrolyte is still largely limited mainl…
Semiconductor quantum dots exhibit great potential for applications in next generation high efficiency, low cost solar cells because of their unique optoelectronic properties. Cu(2)ZnSnS(4) (CZTS) nanocrystals and graphene quantum dots (GQDs) have recently received much attention as building blocks for use in solar en…
Metal nanoparticles have been intensively studied within the past decade. Nanosized materials have been an important subject in basic and applied sciences. Zinc oxide nanoparticles have received considerable attention due to their unique antibacterial, antifungal, and UV filtering properties, high catalytic and photoc…
A rare paramagnetic organometallic nickel(I) olefin complex can be isolated using the ligand bis(5H-dibenzo[a,d]cyclohepten-5-yl)amine. This complex and related nickel(0) hydride complexes show very high catalytic activity in the dehydrogenation of dimethylamino borane with release of one equivalent of dihydrogen.
This contribution reviews the preparation, main characteristics and advantages of macroporous monolithic microreactors for the synthesis of fine chemicals by continuous flow catalytic processes. The review focuses on different types of monolith (polymers, polymer/glass, silica, zeolites) exhibiting macropores of typic…
In this work, we developed two novel strategies to attach metal nanoparticles (Au and Ag) to the surface of graphene nanosheets, in which graphene oxide was first modified by the linking molecule (3-mercaptopropyl)triethoxysilane and then subjected to different treatments including in situ and self-assembled technique…
The correlation between surface profiles of nanostructures and the behavior of scattered light, including specular and diffuse components, is demonstrated in detail. The nanorod arrays with large alignment variation exhibit broadband and omnidirectional anti-reflection properties due to the gradual index profile. This…
Recent reports have revealed that detonation nanodiamonds (NDs) can serve as efficient, biocompatible, and versatile drug delivery platforms. Consequently, further investigations exploring additional therapeutic applications are warranted. Current limitations associated with the non-specific nature of intravenous drug…
Three manganese(III) compounds, [Mn(III)(vanoph)(DMF)(H(2)O)]ClO(4) (1), [Mn(III)(vanoph)(N(3))(H(2)O)]·2H(2)O (2) and [Mn(III)(saloph)(μ(1,3)-N(3))](n) (3), where H(2)vanoph = N,N'-(1,2-phenylene)-bis(3-methoxysalicylideneimine), H(2)saloph = N,N'-(1,2-phenylene)-bis(salicylideneamine) are tetradentate N(2)O(2) ligan…
The creation of novel crown ether-paraquat polypseudorotaxane networks, constructed by bisparaquat monomers threading into the cavity of the crown ether units of linear supramolecular polymers that are formed based on the quadruple hydrogen bonded unit ureidopyrimidinone (Upy) in the concentrated solution, is describe…
In this study, polyvinyl alcohol (PVOH)/corn starch (CS) blend films were prepared using the solution casting method. The biodegradability of the films was investigated based on enzymatic absorbency in water and an acidic solution as well as by burial in soil and compost. The tensile properties were examined using a t…
A highly intense green-emitting phosphor BaY2Si2Al2O2N5 : Eu2+ (BYN : Eu2+) peaking at 511 nm was synthesized by a solid state reaction. The structure refinement, luminescence properties of BYN : Eu2+ phosphors as well as their thermal quenching and the fabrication of white-light-emitting diodes (W-LEDs) were firstly…
A new approach based on solvent and surface effects was developed for controlling the self-assembly of diphenylalanine peptide into microtubes and nanofibers. The HBD/HBA ability and surface tension may be major determinants in the formation of these peptide assemblies. Our results will lead to a better understanding…
Complete phase transition from hexagonal LnF(3) (Ln(3+) = La(3+), Ce(3+), Pr(3+)) to monodisperse ultrasmall (∼7 nm) cubic Ln(0.8)M(0.2)F(2.8) (M(2+) = Ca(2+), Sr(2+), Ba(2+)) disordered solid solution nanocubes was successfully achieved through alkaline-earth doping, which induced great intensification of the near-in…
Single crystals of Li3Cs2B5O10 have been synthesized and its structure determined by single-crystal X-ray diffraction. Li3Cs2B5O10 crystallizes in the non-centrosymmetric space groupC2221 (No. 20). The structure consists of isolated B5O10 groups that are bridged by LiOn (n = 4, 5) and CsOn (n = 8, 10) polyhedra throug…
