Phase transitions in a glassy film of 4-((4-(dibutylamino)phenyl)diazenyl)-biphenyl-2,3′,4′-tricarbonitrile was initiated by a monochromatic X-ray microbeam with λ = 0.71 Å (MoKα). At the site of the film that was directly impacted by irradiation noticeable morphological changes immediately ...

6-(9-Anthryl)- and 6-(1-naphthyl)-9-(dibutylamino)benzo[a]phenoxazin-5-ones exhibited fluorescence maximum at around 700 nm in the crystalline form. Their fluorescence quantum yields were significantly higher than that of previously reported 6-perfluoro[4-methyl-3-(1-methylethyl)pent-2-en-2-oxy]...

Solution polycondensation of 2-N,N-dibutylamino-4,6-dichloro-1,3,5-triazine (BDCT) with various aromatic diamines, including 4,4′-oxydianiline (ODA), p-phenylenediamine (pPDA), m-phenylenediamine (mPDA), o-tolidine (oTD), 4,4′-(9-fluorenylidene)dianiline (BAFL), and 2,4-diamino-6-(N,N-dibutyla...

2-(Dibutylamino)ethanol (DBAE) is a highly effective coreactant for Ru(bpy)32+ electrochemiluminescence (ECL) and Ru(phen)32+ is a well-known ECL luminophore. In this study, ECL of Ru(phen)32+/DBAE has been investigated for the first time. This study has been carried out using cyclic voltametry ...

A method is described for separating and quantifying new cephalosporin derivatives by means of column chromatography on DEAE-Sephadex A-25. The procedure has been used to determine some breakdown products of cefacetril.

Nitrate contamination is increasingly becoming a global health and environmental issue, because nitrate concentration in ground and surface waters has exceeded the safe limit in many places of the world. Removal of such low levels of nitrate from water by conventional processes in an efficient a...

The present work explores the effect of aluminium (Al: 0, 3, 5, 10 & 15 wt%) addition on wear behaviour of copper (Cu). The Cu-Al alloys were fabricated via mechanical alloying and high-pressure hot press. In fact, high-pressure processes are beneficial as they result in obtaining fine microstru...

Cu-bearing Ti alloys could be used as structural biomedical materials where the releasing of Cu ions is beneficial to lower infection incidences associated with surgical implants. The manufacturing of these alloys via powder metallurgy techniques can lower the production costs. In this study thr...

The study investigated the effect of nickel content on the microstructure and mechanical properties of Cu–12Al-xNi alloys prepared using powder metallurgy. The results indicated that the alloys investigated consisted of α-Cu and γ2 (Al4Cu9), containing less than 4 wt% Ni content. The α-Cu ph...

In this study, microstructural and tribological analysis of Aluminium Alloy composites 2024 and 2900 is done. The composite with reinforcements SiC and Al2O3 from 0-20 wt% is prepared by powder metallurgy process. As microwave sintering is the process used the core is much denser than at the sur...

Electrosynthesized cadmium indium selenide (CdIn2Se4) thin films were (photo) electrochemically analyzed by current–voltage characteristics, photoresponse, speed response, electrochemical impedance study, and capacitance–voltage characteristics. The improved photoconversion efficiency of elect...

Non-toxic indium selenide (In2Se3) semiconducting nanoparticles as photosensitizers and an alloyed copper-zinc-tin-sulfide-selenide (Cu2ZnSnS2Se2) coated carbon-fabric as counter electrode are assembled into a solar cell configuration for the first time. In2Se3 nanoparticles with a band gap of 1...

The influence of renal impairment on the intravenous kinetics of aluminum (Al) lactate and the oral absorption of eight representative Al forms was determined. The serum protein binding of Al was assessed. Creatinine clearance in renally impaired rabbits was 23% of controls. Systemic clearance o...

Aluminum is the most abundant metal in the earth’s crust. The widespread occurrence of aluminum, both in the environment and in foodstuffs, makes it virtually impossible for man to avoid exposure to this metal ion. Attention was first drawn to the potential role of aluminum as a toxic metal ove...

Aluminium monitoring is of vital importance to patients with chronic renal failure being treated with intermittent hemodialysis. Aluminium sources in these patients are dialysate contamination and the ingestion of aluminium-containing medications. The development of unbiased and precise methods,...

Nickel(II), zinc(II) and cadmium(II) complexes of two hexapeptides ADAAAC-NH2 and AADAAC-NH2 containing terminal amino, separate aspartyl carboxylate and cysteinyl thiolate donor functions have been studied by potentiometric and spectroscopic techniques. For nickel(II), the amino terminus and th...

Nickel–cobalt hydroxide carbonate, a layered material was synthesized by the co-precipitation method using urea as precipitant agent. This anionic layered material with hexagonal structure is constructed from nickel and cobalt ions within the layers and carbonate anions between the layers. Nick...

A new non-isothermal method of kinetic analysis was employed to investigate the thermal decomposition kinetic modeling of the basic carbonate cobalt nanosheets (n-BCoC) synthesized from spent lithium-ion batteries (LIBs). Fraser–Suzuki function was applied to deconvoluting overlapping complex p...
