A novel method for the conversion of diatom bio-silica structures into nano-porous 3D silicon/magnesium silicon nitride replicas utilising simultaneous metallothermic reduction and nitriding is described. Optical, chemical and structural characterization of the replicas is also presented.
studied by conventional scanning electron microscopy (SEM, JSM-6510LA). Nanocrystalline cellulose was extracted from the natural fibers by the chemical treatments of alkalization and bleaching followed by acid hydrolysis. Alkalization and bleaching resulted in microfibril cellulose, whereas a mix of micro and nanocrys…
In this study which was performed in order to determine the seasonal variations of water quality parameters and algal flora of Tundzha River, samplings were made monthly from 5 different stations along the river. A total of 138 taxa from Chlorophyceae (65 taxa), Bacillariophyceae (46 taxa), Euglenophyta (13 taxa) and…
Two novel Mg-Li-Al based alloys, namely Mg-9 wt% Li-7 wt% Al-1 wt% Sn (LAT971), and Mg-9 wt% Li- 5 wt% Al -3 wt% Sn- 1 wt% Zn (LATZ9531), were cast and hot rolled at 573K. Phase analysis revealed the presence of major Mg-rich (α) and Li- rich (β) phases along with precipitates. Nano-mechanical properties (via nanoinde…
A new mechanism for formation of TiO 2 nanotubes involving the growth of some nanopores and degeneration of others is proposed.
Active matter, whose motion is driven, and glasses, whose dynamics are arrested, seem to lie at opposite ends of the spectrum in nonequilibrium systems. In spite of this, both classes of systems exhibit a multitude of stable states that are dynamically isolated from one another. While this defining characteristic is h…
The corrosion inhibition characteristics of Garcinia indica extract (GIE) on the corrosion of aluminium and 6063 aluminium alloy in 1.0 M phosphoric acid solution were studied by using potentiodynamic polarization using Tafel extrapolation technique and electrochemical impedance spectroscopy (EIS) techniques at differ…
The copper complex of a polydentate non-symmetrical Schiff base ligand [LCu]2, prepared by template synthesis, has been reacted with the series of lanthanide ions. This complex used as a ligand possesses two functions (phenol and oxime) able to coordinate the Ln ions and, according to the Ln ion, three types of comple…
A superstructure was formed on form I of 6-chloro-2, 4-dinitroaniline crystals. It was observed using a slow evaporation solution growth technique and crystals grown from slow evaporation of the filtrate in anti-solvent precipitation. The thickness of 2D petals in the superstructure is about 100 nm.
Cuprobismutite group minerals have been discovered for the first time in Japan from the Obari mine, Yamagata Prefecture. Furthermore, many kinds of Bi–sulfosalts and Bi–tellurides have been found from this mine. Cuprobismutite occurs as irregular particles which are intergrown with makovickyite. The empirical formula…
According to developing technology and conditions of modern life, use of radiation is rapidly increased. Unwittingly, our organs and tissues are exposed to radiation continuously. In order to avoid exposure to this radiation, some studies were carried out on protective clothing. In this study, radiation keeping proper…
De novo synthesized amphiphilic peptides can be easily designed to form various nanostructures. Natural biomineralization creates the most intricately stunning inorganic structures, such as diatoms and shells, in which peptides play an important role. Here, we present the biomineralization of three designed amphiphili…
In this work, we show local laser-induced heating in fluids with gold nanodot arrays prepared by electron-beam lithography that cover resonances in the near infrared spectral range from 750 nm to 880 nm.
Three palladium atoms connect two π-expanded tetracene ligands to extend π-conjugation, realizing low energy absorption in the infrared region.
In this article, a nanoporous chitosan polymer membrane was successfully produced and applied as microdialysis membrane for in vitro sampling of biomolecules. With the use of nanoparticle leaching technique, porogenic gelatin nanoparticles formed nanopores in the chitosan‐based membrane to create a secure implantable…
We have demonstrated a microchannel-based, surface-enhanced Raman spectroscopy (SERS) sensing approach for integrated microfluidic analysis developed using standard micro-fabrication technology. Our approach allows high-sensitivity SERS sensing with a comparatively low-excitation optical power intensity and large cros…
Polyelectrolyte (PE) brush-like molecules are very useful in modifying the physical properties of surfaces in solution. Polyelectrolytes strongly influence the electrostatic potential of the PE-covered surface of nanoparticles and also the ion concentration near the surface. These parameters further affect the mobilit…
This work is an investigation of the electrografting of in situ generated 4-sulfonic acid phenyldiazonium salt (PD-SO 3 H) on Nitinol followed by layer-by-layer (LBL) deposition of polyelectrolyte (chitosan and alginate) multilayers (PEM). Nitinol is interesting for many biomedical applications. A great deal of attent…
Molecular magnetism is considered an area where magnetic phenomena that are usually difficult to demonstrate can emerge with particular clarity. Over the years, however, less understandable systems have appeared in the literature of molecular magnetic materials, in some cases showing features that hint at the spontane…
EPS off-grade is commonly known as waste in the manufacturing process of Expanded Polystyrene (EPS). It is worthwhile to recover such waste by improving its properties. However, blowing agent used in the EPS would be a drawback in the recovering process. Our research implemented the improvement by the addition of impa…
