Albumin-based drug delivery has been demonstrated to be useful for achieving improved cancer therapy, largely due to its passive target toward tumor via the enhanced permeability and retention effect and the increased demand for albumin by tumor cells as source of energy and amino acids. However, albumin lacks not onl…
Antifouling nanofibers with zwitterionic materials on surfaces that can prevent the nonspecific adhesion of biomolecules and microorganism are in demand for high efficiency biosensors and affinity membranes. The functionalization of zwitterionic sulfobetaine on surfaces of PVA-co-PE nanofiber membrane via click chemis…
Dysfunctional intracellular enzymatic activity is believed to be an underlying cause of a myriad of diseases. We present the first use of surface enhanced Raman scattering (SERS) as a detection technique capable of reporting intracellular activity of a specific enzyme. Careful choice of reagents allowed the preparatio…
The incorporation of amphiphilic tetrapyrrole macrocycles in organized media is of great value for a variety of fundamental photochemical studies, yet work to date has chiefly employed porphyrins rather than chlorins or bacteriochlorins. The latter absorb strongly in the red or near-infrared spectral region, respectiv…
A series of substituted 1,4-benzenediboronic acids (BDBA) was synthesized and their thermal properties investigated. Two diboronic acids were studied as building-blocks for covalent organic framework (COF) formation, namely 2,5-dimethoxy-1,4-benzenediboronic acid and 2-nitro-1,4-benzeneboronic acid. Interestingly, sub…
Molecular aspects of nanoparticle adsorption to the interface between two immiscible liquids are investigated using molecular dynamics simulations. The effect of particle amphiphilicity on the adsorption and desorption processes is examined by comparing the simulation results of a Janus particle to a plain particle. T…
A series of Au/CuOx-TiO2 with various Cu/Ti ratios were prepared. CuOx/TiO2 was prepared by incipient-wetness im- pregnation with aqueous solution of copper nitrate. Au catalysts were prepared by deposition-precipitation method at pH 7 and 338 K. The catalysts were characterized by inductively-coupled plasma-mass spec…
A biomolecular system representing the first realization of associative memory based on enzymatic reactions in vitro has been designed. The system demonstrated "training" and "forgetting" features characteristic of memory in biological systems, but presently realized in simple biocatalytic cascades.
An azobenzene-linked symmetrical gemini α-helical peptide was designed and prepared to realize the light-switched self-assembly. With the reversible molecular structure transition between Z- and U-structures, the morphology of the self-assembled gemini α-helical peptide can reversibly change between nanofibers and nan…
Carboxylated SiO2-coated α-Fe nanoparticles have been successfully prepared via CaH2-mediated reduction of SiO2-coated Fe3O4 nanoparticles followed by surface carboxylation. These α-Fe-based nanoparticles, which are characterized by ease of coating with additional functional groups, a large magnetization of 154 emu pe…
CuO nanowires were synthesized by in situ thermal oxidation of Cu2O for the first time in the temperature range of 300–750 °C in air. In this process, the effects of annealing temperature and growth time on the growth of CuO nanowires were investigated by SEM, XRD, EDS mapping and line-scan profile measurements. We fo…
A novel solid acid material, magnetically separable and SO3H-functionalized porous carbon nanosphere, was facilely synthesized by a simple activation route. The SiO2 layer protected the magnetic core from dissolving during the process of activation with ZnCl2, and retained the highly magnetic property. The obtained ma…
The discrimination of ferrous and ferric states in the human body is one of the basic issues for disease control and prevention because Fe(II) and Fe(III) are a crucial redox pair during the process of material and energy metabolism. Herein, aqueous CdTe quantum dots (QDs) with diversified surface functionalities are…
The aim of this study was to relate the combustion rate of solid fuel for iron ore sintering process to its physical and chemical properties. In this study, we used 23 carbon materials including cokes, anthracites, charcoals, and so on. The physical and chemical properties of the carbon materials such as proximate and…
Novel Na3Li3Sc2F12 microcrystals with cubic-phase structure, (110)-truncated cubooctahedral morphologies, as well as self-activated white-light luminescence are reported for the first time. Doping of this cubic polymorph with optically active lanthanide ions or ion-pairs illustrates its suitability as a host lattice f…
As a function of packing fraction at zero temperature and applied stress, an amorphous packing of spheres exhibits a jamming transition where the system is sensitive to boundary conditions even in the thermodynamic limit. Upon further compression, the system should become insensitive to boundary conditions provided it…
A series of symmetric and asymmetric 1,6,7,12-tetrachloroperylene bisimides (PBICls) were synthesized and modified by siloxane substituents at the imide nitrogen atom. Siloxane substitutions do not apparently affect the electronic properties of PBICIs as demonstrated by CV experiments. They display both thermotropic a…
The geometries of phosphorus-doped gold clusters, AunP− (n = 1–8), have been investigated using different density functionals and basis sets. B3LYP and PBE functionals with 4 basis sets (aug-cc-pVDZ, 6-311++G**, CRENBL ECP and LANL2DZ ECP) are chosen for geometry optimisation. Many low-lying structures are obtained fo…
Uniform M3PMo12O40·nH2O (M = NH(4+), K(+), Cs(+)) rhombic dodecahedral nanocrystals are successfully obtained using mild hydrothermal conditions or room temperature chemical precipitation method for their self-organization. The reaction temperatures and times play important roles in the possible growth proceeding of t…
The high surface area of multi-walled carbon nanotubes (MWCNTs) tends to adsorb a large variety of toxic chemicals, which may enhance the toxicity of both MWCNTs and chemicals to organisms. In order to evaluate the combined toxicity of nonylphenol (NP) and MWCNTs to the earthworm Eisenia fetida in soil, artificial soi…
