This study aims to use sweet sorghum juice (SSJ) to produce an environmentally friendly biopolymer of polyhydroxyalkanoates (PHAs) by bacteria isolated from soil. Among 18 isolates, only 3 isolates, coded as S4, S6, and S11, were chosen to produce PHA via batch fermentation compared to 3 strains of Alcaligenes eutroph…
To promote possible applications of graphene in molecular identification based on stacking effects, in particular in recognizing aromatic amino acids and even sequencing nucleobases in life sciences, we comprehensively study the interaction between graphene segments and different cyclic organic hydrocarbons including…
The traditional concept of the synthesis of semiconductor nanocrystals (NCs) by solvent routes usually performed under high temperatures, causes the semiconductor materials to nucleate and grow into various shaped NCs in solution. Therefore, these methods are named as “solvent-thermal approachs”. In this work, we desc…
porphyrin were synthesized in the 3 solvents mixture by Adler-Longo method. The porphyrin purification was carried out by ethyl acetate extraction.
Two 2D silver lamella frameworks, [Ag4(C5H4NS)2(NO3)2]n (1) and [Ag3(C5H4NS)2]n·nClO4 (2) based on binuclear units have been solvothermally synthesized. The C5H4NS ligand was in situ generated from the cleavage of bis(2,4,6-trimethyl-3,5-bis((pyridin-2-ylthio)methyl)phenyl)methane (bmpm). Furthermore, the formation of…
A solid phase preconcentration procedure using SBA‐3 nanosorbent for the fast separation and preconcentration of crystal violet (CV) in water samples by fiber optic‐linear array detection spectrophotometry (FO‐LADS) is presented. Experimental parameters including pH, sample volume, amount of sorbent, type, volume, and…
Issues of doing research, designing high performance concrete compositions, optimal application of this material as in the field of erecting unique buildings and constructions, so in large-scale construction, are discussed in the article. Requirements to high performance concrete are set; the existing practice of its…
Here we report on our investigations into the aggregation behaviour and optoelectronic properties of organic (semi)conductor-containing π-conjugated rod–coil–rod triblock materials. The facile synthesis of these rod-like tetra(aniline) (TANI) containing materials was achieved by a one-step condensation reaction of mon…
A versatile and effective method by which a wide range of nanoparticulate materials can be attached to a variety of oxidic surfaces is presented. After synthesizing the nanocrystals (PbS, CdSe, CdSe@CdS core–shell, Au) via standard hot injection routes, the stabilizing ligands are exchanged to 3-mercatopropyl-trimetho…
(1-x) BaTiO 3 -x Bi ( Mg 1/2 Ti 1/2 ) O 3 (BT-BMT, 0.3 ≤ x ≤ 0.6) ceramics were prepared by the conventional mixed oxide method. Dielectric measurements showed highly diffusive and dispersive relaxor-like characteristics for all compositions. For 0.3 ≤ x ≤ 0.4, all these compositions possess a stable dielectric permit…
Phase field modeling has become a widely used framework in the computational material science community. Its ability to model different problems by defining appropriate phase field parameters and relating it to a free energy functional makes it highly versatile. Thermodynamically consistent partial differential equati…
With recent advances in nanotechnology, carbon nanotubes (CNTs) have been extensively studied as substrates for cell culture, drug delivery systems, and medical implant materials. However, surprisingly little is known about the effect of CNTs on collective cellular processes (e.g., adhesion, proliferation, and differe…
Directed self-assembly (DSA) of block copolymers (BCPs) is a promising technology for advanced patterning at future technology nodes. We use Self-Consistent Field Theory (SCFT) to model directed self-assembly (DSA) of PS-PMMA block copolymers on chemically patterned surfaces (chemoepitaxy). We consider the scenario in…
Some findings in heterogeneous nucleation that the structural features of a growing crystal are usually inherited from the heterogeneous nucleus, although attracting more and more attention, are not yet well understood. Here we report numerical simulations of copper nucleation on bending graphene (BG) to explore the m…
We synthesized a spiropyran–cholesterol conjugate (1) and studied its gelation and photochromic properties. The compound 1, when dissolved in carbon disulfide (CS2), forms a homogeneous gel at −40 °C due to the van der Waals interaction between the cholesterol moieties. UV or visible light irradiation of the CS2 sol o…
In order to clarify the ultra low friction mechanism of Carbon Nitride (CNx) coatings under blowing dry Ar, thickness and area of transfer layers on mating surface were in-situ observed with an optical microscope during sliding against a sapphire hemisphere under blowing dry Ar. During sliding, thickness of transfer l…
The potential of surface self-propagating high-temperature synthesis (SSHS) for obtaining (CuO-CeO 2 )/glass cloth catalysts is demonstrated. The dependence of the structural and catalytic properties of the catalysts on their preparation conditions (nature of the fuel component) is considered. X-ray diffraction, elect…
Ultradisperse cubic silicon carbide (β-SiC) has been obtained by direct plasmadynamic synthesis in pulsed supersonic carbon-silicon plasma jet incident on a copper obstacle in argon atmosphere. The powdered product has a high content of β-SiC in the form of single crystals with average size of about 100 nm and nearly…
High-resolution multilayer plasmonic nanostructures are made in a single fabrication step by nanocutting a gold and parylene C bilayer.. A silicon stamp is used to cut the gold film and vertically displace the nanocut shapes into the polymer. Periodic Au nanopatterns in single and double-layer configurations are fabri…
We describe a convenient route to the alignment of cyclic peptide nanotubes (CPNs). The key lies in the use of nanostructured ionic liquids. An ionic liquid supported membrane with orientated domains is demonstrated, leading to aligned CPNs within a solid membrane.
