A set of donor–π-acceptor–π-donor type ferrocenyl substituted BODIPYs were designed and synthesized by the Sonogashira coupling reaction. These compounds exhibit red shifted absorption and poor fluorescence. The electrochemical properties of these compounds exhibit strong donor–acceptor interactions. The crystal struc…
The unique one dimensional structure and the positively charged external surface are the driving forces for imogolite clay nanotubes emerging as one of the most promising nano building blocks for various hybrid materials. This paper reviews the utility of imogolite in organic–inorganic nanohybrids, including polymer–i…
The influence of Al doped on work function of ZnO thin film with C-axis preferred orientation were analyzed both theoretically and experimentally. Pure ZnO and Al-doped ZnO(ZnO:Al) films were deposited on n-type Si substrate by radio frequency (RF) magnetron sputtering. Surface work function were calculated using the…
Silk produced by the silkworm Bombyx mori has gained a second youth as a sustainable material for high-technology applications. Here, we report a simple and cost-effective fabrication technique which allows the preparation of free-standing micropatterned pure protein films under ambient processing conditions. In this…
Nanostructured silicon hollow spheres with a thin shell have been synthesized by magnesium reduction of silica spheres, which possess a high BET surface area and are electrochemically active in capacitive energy storage with a maximum specific capacitance of 193 F g(-1) in the neutral Na(2)SO(4) aqueous solution.
Superparamagnetic iron oxide nanoparticles (SPIONs) and oxaliplatin (OHP) were in-situ encapsulated in pectin cross-linked with Ca(2+) forming 100-200 nm sized magnetically functionalized pectin nanocarriers, referred here as MP-OHP nanocarriers. The scanning electron microscopy (SEM) and transmission electron microsc…
The formation of helical self-assembled fibres by a C(3) symmetric molecule incorporating three tetrathiafulvalene units is shown to be influenced dramatically by the processing conditions, leading to a variety of different chiral forms, including unprecedented croissants.
A new kind of β-MnO2 nanorod (NR)–poly(vinylidene fluoride) (PVDF) functional composite with a high dielectric constant can be prepared by addition of β-MnO2 NRs to PVDF. The microwave absorption properties of β-MnO2 NRs, which were synthesized by a simple hydrothermal method on a large scale at low temperature, have…
A vital organizational feature of living cells is that of compartmentalization. This allows cells to run concurrently incompatible metabolic processes and to regulate these processes by selective trans-membrane transport. Although strategies that effectively mimic cell function in simple architectures have been resear…
Graphene materials with different characteristics in terms of sheet size and defects (structural and/or functional groups) were obtained by the reduction with hydrazine of two graphene oxides with similar oxygen content, but with functional groups of different type and location. The oxides were prepared from two synth…
The corrosion inhibition effect of 4-amino-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-thiol (APTT) was evaluated for mild steel in 1M HCl solution using gravimetric measurement, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Inhibition efficiencies obtained ranged between 54.3 to 95.7% in the…
There have been impressive developments in the field of nanotechnology in the recent past, with numerous methodologies formulated to synthesis bionanoparticles using plants. Currently, there is a growing need to develop environmentally benign nanoparticles synthesis processes that do not use toxic chemicals in the syn…
Abstract- Chitosan biopolymer represents an attractive alternative to other bio materials because of its significant physico– chemical behaviours. In order to improve chitosan’s performance, chemical modification has been carried out. Chemical modification that lead to the formation of chitosan derivatives, grafted ch…
Here we report the photocatalytic properties of semiconductor SnO2/CdS heterostructure nanocrystals. A type-II SnO2/CdS heterostructure has been synthesized from a single-source precursor and its structure was determined using XRD, HRTEM, elemental mapping and line scan EDAX analysis. A time resolved spectroscopic stu…
A novel 3,4,4a-trihydroxanthene-fused pyrrole 2 was synthesized by the reaction of 2,3,4,4a-tetrahydro-1H-xanthen-1-one with 3-phenyl-2H-azirine in the presence of LDA. Utilizing this pyrrole 2, a NIR BODIPY 1 (λ(abs) = 732 nm, λ(em) = 747 nm) has been prepared. The new BODIPY 1 was stable, non-cytotoxic, and suited t…
Recent developments in supramolecular strategies have enabled us to construct novel well-defined assemblies of dye molecules. These fundamental researches of such organic materials also entail the synthetic and photophysical processes of molecular aggregates at the nano- and micro-meter scale, since their optical prop…
Ionic liquids (ILs)-stabilized iron oxide (Fe(2)O(3)) nanoparticles were synthesized by the ultrasonic decomposition of iron carbonyl precursors in [EMIm][BF(4)] without any stabilizing or capping agents. The Fe(2)O(3) nanoparticles were isolated and characterized by X-ray powder diffraction, transmission electron mic…
A modern highway must be capable of proving traffic safety, comfort to passengers as well as efficient and economical transportation. In view of the increase in the number of traffic accidents due to the developments in automotive industry, the traffic safety has gathered too much consideration in recent years. Skid r…
Conductive polypyrrole (PPy)‐manganese ferrite (MnFe 2 O 4 ) nanocomposites with core‐shell structure were synthesized by in situ polymerization in the presence of dodecyl benzene sulfonic acid (DBSA) as the surfactant and dopant and iron chloride (FeCl 3 ) as the oxidant.
