Corn stalk is a renewable natural resource that currently has limited industrial utilization. The objective of this study was to examine some chemical properties of corn stalk (holocellulose, \alpha-cellulose, lignin and ash content, alcohol-benzene, hot and cold water solubility, and solubility in dilute alkali [1% N…
The synthesis, physico-chemical behavior, and in vitro intracellular degradation of new biodegradable graft, diblock or multiblock polymer carriers that were designed to deliver bioactive compounds by passive tumor targeting were investigated. The graft polymer carriers consisted of the N-(2-hydroxypropyl)methacrylami…
Chitin fiber (CHF) and chitosan (CS) 3D composite rods with layer-by-layer structure were constructed by in situ precipitation method. CHF could not be dissolved in acetic acid aqueous solution, but CS could be dissolved due to the different deacetylation degree (D.D) between CHF and CS. CHF with undulate surfaces cou…
The difference in electrostatics and reduction potentials between manganese ortho-tetrakis(N-ethylpyridinium-2-yl)porphyrin (MnTE-2-PyP) and manganese meta-tetrakis(N-ethylpyridinium-3-yl)porphyrin (MnTE-3-PyP) is a challenging topic, particularly because of the high likelihood for their clinical development. Hence, a…
Medicinal carbon (MC) films, which can be taken more easily than other dosage forms, were prepared using sodium carboxymethyl cellulose (CMC), hydroxypropylmethyl cellulose (HPMC) and alginic acid sodium (ALG) as film base materials. Brilliant blue FCF (BB) was used as a model drug. The films containing MC had suffici…
Al-doped ZnO thin films were prepared on the (0001) sapphire (c-Al2O3) substrates by atomic layer deposition (ALD) using alternating pulses of Zn(C2H5)2, Al(CH3)3 and H2O precursors and post-deposition high-temperature annealing. Photoluminescence (PL) spectroscopy showed that the threshold of stimulated emission decr…
Free-standing TiO2 nanotubes with both their ends open are required in many applications. This article reports the authors’ latest progress in meeting these requirements. Elevating the voltage at the end of an anodization process can break the adhesion of the TiO2 nanotube layer to the underlying Ti substrate and simu…
Fabrication and property of c-axis-oriented KSr2Nb5O15 (KSN) ceramics were examined. Particle-oriented KSN was fabricated by using a rotating magnetic field and subsequent sintering. KSN fine powder was prepared by conventional solid-state reaction and grinding processing. C-axis-oriented KSN green compact was fabrica…
Homologous compound In2−xGaxO3(ZnO)3 (x ≈ 0.18) nanobelts were successfully synthesized in high yield by a simple thermal vapour method for the first time. Two sets of peaks appear in X-ray diffraction pattern. One is attributed to wurtzite ZnO, while the other is indexed to rhombohedral In2−xGaxO3(ZnO)3 (x ≈ 0.18) wi…
Layered-antiferromagnetic compound CuCrS 2 has been prepared by different methods. The analysis of X-ray diffraction patterns of different samples gave significant amount of vacancy-disorder of Cr-atoms within the layers. Extended period of sintering above 900 °C increases the transfer of Cr-atoms to the interstitial…
Fine grained samples with a nominal composition of Bi0.5Sb1.5Tex (x=3.0 to 3.4) were prepared by mechanical alloying (MA). Average grain sizes were found to range from 1.0 to 2.1 μm. Tellurium precipitation at x=3.1 was observed by scanning electron microscopy (SEM), X-ray diffraction and differential thermal analysis…
This paper describes the synthesis and physical properties of an uniquely asymmetric heptanickel string complex exhibiting a charge disproportionate model along the linear nickel framework.
The effect of 2‐phenyl‐3‐nitroso‐imidazo[1,2‐a]pyridine (PNIP) on the corrosion inhibition of carbon‐steel in 0.5 M HCl was studied by weight loss and different electrochemical techniques such as electrochemical impedance spectroscopy (EIS), potentiodynamic polarization. The obtained results showed that PNIP effective…
With especial regard to hydrogen electrode, the theoretical fundamentals of electrode potential, the most important reference electrodes and the electrode potential measurement have been discussed. In the case of the hydrogen electrode, it have been emphasised that there is no equilibrium between the hydrogen molecule…
Cd(OH)(2) nanorings were synthesized in high yield via a one-step solution phase synthesis process at room temperature, in which the co-existence of ethanol and ammonia is the key factor for the formation of such a ring structure. Further calcination of the Cd(OH)(2) nanorings results in the formation of CdO nanorings.
A tripod zinc porphyrin (TPZn(3)) forms a stable 1:1 complex with gold(III) tetra(4-pyridyl)porphyrin (AuTPyP(+)) and free-base tris(4-pyridyl)porphyrin (2H-Py(3)P) in nonpolar solvents. The strong binding of TPZn(3) with AuTPyP(+) or 2H-Py(3)P results from the encapsulation of AuTPyP(+) or 2H-Py(3)P inside the cavity…
A nanotoroidal open-ended tubule structure could be formed by the self-assembly of an eight substituted oxacalix[4]arene in the solid state, and THF molecules were accommodated in the hole.

Iron carburization is one of the most important reactions in iron making process. If the rate and efficiency of carburization reaction are increased, energy consumption of the process will be reduced to a large extent. The purpose of this study is to clarify the effect of carbon structure on initial iron carburization…
Gold nanoparticles immobilized on gold surfaces (AuNPs/Au) function as an excellent SERS substrate for the detection of bacteria biomarkers. The possibility of the reactivity of bacteria biomarkers on such a nanoparticle-based substrate poses complications for the spectroscopic identification and quantification. This…
