Single chambered microbial fuel cell (sMFC) could be used for wastewater treatment as well as to generate electricity. Bioelectrochemical treatment of synthetic acetate based wastewater with simultaneous power generation was studied in tubular type air cathode sMFC. In order to improve the efficacy of MFC, three diffe…
We have investigated the effect of nanorods on the symmetry breaking of a model diblock copolymer under cylindrical confinement using coarse-grained molecular dynamics. Unlike nanoparticles, nanorods can readily be interconnected with each other and also induce connection across self-assembly domains at much lower loa…
Rheological fluids belong to the group of smart materials which can also form a component of some textile products. In this study shear thickening fluids (STF) and magnetorheological fluids (MRF) were synthesised. STF is a colloidal suspension of silica nanoparticles in an organic liquid carrier. The viscosity of STFs…
Fowler and Pisanski showed that the Fries number for a fullerene on surface Σ is bounded above by |V|/3 , and fullerenes which attain this bound are exactly the class of leapfrog fullerenes on surface Σ. We showed that the Clar number of a fullerene on surface Σ is bounded above by (|V|/6)-χ(Σ) , where χ(Σ) stands for…
The chemical precipitation method was combined with the membrane separation to treat the simulated radioactive wastewater containing strontium in the paper. The calcium carbonate powder was used to prepare the seed and the sodium carbonate was selected as the precipitant. Sr2+ and CO32- constantly crystallized on the…
For the first time, galvanic deposition of Ti is reported from aqueous solutions containing 17 mM HF and 10 mM K 2 TiF 6 at pH 2.73 onto Al 6061 alloy. X-ray diffraction yields peaks consistent with a polycrystalline Ti deposit, and electrical resistivity measurements are also consistent with metallic Ti, not TiO 2 .…
Uniaxially p-n junction gallium nitride nanowires have been synthesized via metal‐organic chemical vapor deposition method. Nanowires prepared on Si(111) substrates were found to grow perpendicular to the substrate, and the transmission electron microscopy studies demonstrated that the nanowires had singlecrystalline…
Electromagnetic shielding (EMS) fabrics often need to design rectangular holes for application. However, there is not a mature approach to predict the shielding efiectiveness (SE) of the EMS fabric with rectangular hole. This paper proposes that there are a number of loose regions of conductive flbers on the hole edge…
Investigations focused on physico-chemical modifications of a polyethylene terephthalate (PET) nonwoven fabric fibre surface. To improve the adhesive properties of textile products towards TiO2, their surface was treated in low-temperature plasma (cold plasma). Plasma treatment of PET fabrics was performed in carbon d…
The application of two‐phase computational fluid dynamics (CFD) for simulating crater‐like Taylor cone formation dynamics in a viscous liquid is a challenging task. An interface coupled level set/volume‐of‐fluid (CLSVOF) method and the governing equations based on Navier‐Stokes equations were employed to simulate the…
An efficient and divergent one-pot synthesis of 2,3-dihydro-1H-pyrroles, 3-alkyl-1H-pyrroles and 3-alkenyl-1H-pyrroles from readily accessible 2,4-pentadienenitriles with isocyanide based on reaction condition selection has been described. The reaction of 2,4-pentadienenitriles with ethyl isocyanoacetate undergoes a f…
Design of a bio-inspired material, where a competition between copper ions and their triflate counterions to the grafted polyamine is evidenced.
Millimeter size high quality crystals of CuGaS2 were grown by chemical vapor transport. The highly ordered chalcopyrite structure is confirmed by X-ray diffraction and Raman spectroscopy. According to energy dispersive X-ray spectroscopy the composition of the crystals is very close to the formula CuGaS2. Room tempera…
The polygon-like resonant excitation of coupled skyrmions can be controlled in nanoscale magnets by a dual-frequency microwave field.
We present a robust two dimensional coordination polymer, [Ni2(L)2(N(CN)2)2]n (1) (LH = 2-((1-(pyridin-2-yl)ethylimino)methyl)phenol; N(CN)2(-) = dicyanamide ion) using a chiral Schiff base (LH), which shows diastereoselectivity in the structure via a chiral self-discrimination process, ferro- and antiferromagnetic in…
Objective(s): A simple and "green " method was developed for preparing zinc oxide nanoparticles (ZnO-NPs) in aqueous starch solutions. Starch was used as a stabilizer to control of the mobility of zinc cations and then control growth of ZnO-NPs prepared via a sol-gel method. Because of the special structure of the sta…
Polysulfone aramid fiber is one kind of high temperature fibers. In the paper, thermal degradation behavior and kinetics of polysulfone aramid fiber were investigated by thermogravimetric analysis and differential thermogravimetric at different heating rates under nitrogen and air, respectively. The experimental resul…
Invisibility cloaks have experienced a tremendous development in the past few years, but the current technologies to convert the cloaks into practical applications are still facing numerous bottlenecks. In this paper, we provide the review of the challenges and recent progress in the invisibility cloaks from a practic…
Zinc sulfide oxide Zn(O,S) buffer layers were prepared by a chemical bath deposition (CBD) method, and the effects of the deposition time on the structure and performance of the Cu(In,Ga)Se2 (CIGS) solar cells were investigated by structural, optical and electrical characterizations. The CBD deposition time affected t…
The problem of transient layer formation in given composition between inclusions and matrix can be solved using mathematical modeling. This paper suggests a suitable model taking into account multi staging of chemical conversion. Numerical realization of this model allows studying the dynamics of transient layer forma…
