A detailed statistical investigation was conducted in order to correlate some important biodiesel properties with the respective methyl ester weight composition in fatty acids. The examined properties were cetane number, density, kinematic viscosity and heating values (lower and higher). The cho...

ObjectivesTo investigate the ability of cis-2-decenoic acid (C2DA) to induce dispersion in single-species biofilms formed by Streptococcus mutans and Candida albicans, as well as to remove their bacterial-fungal dual-species biofilms when combined with low concentrations of chlorhexidine (CHX).

In the present work we report on the compounds characteristic of larval food (royal jelly, RJ) of the honeybee (Apis mellifera L.) that were identified in 34 different samples of genuine honey and in 3 sugar-adulterated “herbal honeys” by using solid-phase extraction and gas chromatography–ma...

This study describes the biosynthesis and thermal degradation of medium-chain-length polyhydroxyalkanoate (PHA), focusing on 2-alkenoic acids as a recyclable carbon source. Using metabolically engineered Escherichia coli, PHA consisting of 3-hydroxydecanoate (3HD) was synthesized from 2-decenoic...

AimsIn the present work we investigated the in vitro effect of cis-4-decenoic acid, the pathognomonic metabolite of medium-chain acyl-CoA dehydrogenase deficiency, on various parameters of bioenergetic homeostasis in rat brain mitochondria.

A protein fraction which cleaves linoleic acid into 1-octen-3-ol and 10-oxo-trans-8-decenoic acid was isolated from a mushroom extract by precipitation with poly(ethylene glycol). This fraction was incubated with linoleic acid in the presence of either gaseous oxygen-18 or water containing the i...

1-Octen-3-ol and 10-oxo-trans-8-decenoic acid (ODA) are the products of the enzymic breakdown of linoleic acid (LA) in mushrooms by a lipoxygenase and a hydroperoxide lyase. Based on this reaction, natural 1-octen-3-ol and ODA can be produced with a crude enzyme homogenate from mushrooms in a bi...

A series of octahedral phenanthroline cobalt chlorides, aqua and carbonates complexes have been prepared, characterized, and their antibacterial activity was studied in detail in terms of zone inhibition and minimum inhibitory concentrations. Their antioxidant activities were studied by measurin...

Cobalt super-microparticles anchored on nitrogen-doped graphene (Co–NG) were prepared using an inexpensive method and were tested for heterogeneous oxidation of aniline with peroxymonosulfate (PMS) in aqueous solutions. The crystal structure, morphology, and textural properties of Co–NG hybrid...

Single crystals of potassium magnesium chloride sulfate (KMCS) doped with cobalt ions were grown by slow cooling method. Powder XRD study confirmed the monoclinic structure of the grown crystals. The functional group vibrations were checked through FTIR spectroscopy measurements. In optical stud...

Efficient water remediation relies on robust and capable catalysts to drive the cutting-edge purification technologies. In this work, Prussian blue analogues (PBA) are engaged as the starting materials to fabricate various transition metal (TM)@carbon composites for water decontamination. The en...

Single crystals of K2Co(SO4)2·6H2O were grown from solution using the temperature reduction method enhanced by the axial low frequency vibration control technique (AVC-technique). Physical modeling of heat-mass transfer in solution under the AVC action was performed. The growth rate of the AVC ...

Samples of the empirical formula K2+Nix2+Co1−x2+SO42⋅6H2O were grown with a partial occupation of the cations Co and Ni. Mixed crystals with good optical quality were obtained by the slow evaporation growth method. In the decomposition process, these crystals suffer a mass loss of approximately ...

The positive effects of zirconium phosphate (ZrP)-modified highly ordered mesoporous KIT-6 support for an insignificant aggregation of the supported cobalt nanoparticles (CoZrP/KIT-6) were investigated by CO hydrogenation to hydrocarbons such as Fischer-Tropsch synthesis (FTS) reaction. The role...

Cobalt phosphide has been extensively studied as non-precious metal-based robust electrocatalyst for hydrogen evolution reaction. Innovation breakthrough is still highly desired to enhance its catalytic efficiency. In this work, through rational engineering strategy, a controlled inner-porous Co...

In the paper, conductive atomic force microscopy (CAFM) technique was used, for the first time, to obtain direct evidence of oxide-film removal during fluxing, via measuring the electrical conductivity of aluminum sample surfaces. The CAFM results show that the F− ions from the flux loosened the...

Aluminum (Al) is a toxic metal, and excessive Al accumulation causes immunosuppression. Deferiprone (DFP) is a well-known chelator and used in dialysis patients for removing Al from tissues. The present study aimed to investigate whether DFP treatment can attenuate immunotoxicity induced by alum...

Ultrasonic humidifier use is a potential source of human exposure to inhalable particulates.
