Biological and chemocatalytic processes are tailored in order to maximize the production of sustainable biodiesel from lignocellulosic sugar. Thus, the combination of hydrotalcite-supported copper(II) and palladium(0) catalysts with a modification of the fermentation from acetone-butanol-ethanol to isopropanol-butanol-ethanol predictably produces higher concentrations of diesel-range components in the alkylation reaction.


Hydroxyapatite-nanosphere supported ruthenium(0) nanoparticle catalyst for hydrogen generation from ammonia-borane solution: kinetic studies for nanoparticle formation and hydrogen evolution

The development of readily prepared effective heterogeneous catalysts for hydrogen generation from ammonia-borane (AB; NH3BH3) solution under mild conditions still remains a challenge in the field of "hydrogen economy". In this study, we report our finding of an in situ generated, highly active ruthenium nanocatalyst for the dehydrogenation of ammonia-borane in water at room temperature. The new catalyst system consists of ruthenium(0) nanoparticles supported on nanohydroxyapatite (RuNPs@nano-HAp), and can ...
Cytochrome P4501A and associated mixed-function oxidase induction in fish as a biomarker for toxic carcinogenic pollutants in the aquatic environment
Arinc, E; Sen, A; Bozcaarmutlu, A (Walter de Gruyter GmbH, 2000-06-01)
Polycyclic aromatic hydrocarbons (PAHs), dioxins, dibenzofurans, and polychlorinated biphenyls (PCBs) present in polluted environment induce cytochrome P4501A (CYP1A) isozyme in fish, which in turn results in a marked increased production of carcinogenic metabolites from PAHs. The induction of hepatic CYP1A in fish by certain classes of chemicals has been suggested as an early warning system, a "most sensitive biological response" for assessing environmental contamination conditions. This has implications f...
Development of a synthetic strategy for Water soluble tripodal receptors: Two novel fluorescent receptors for highly selective and sensitive detections of Fe3+ and Cu2+ ions and biological evaluation

A general synthetic strategy is developed to synthesize water soluble receptors by employing tripodal system based on a cyclotriphosphaze platform. The developed model is successfully synthesized and characterized by using elemental analysis, FT-IR, MALDI-TOF, H-1 NMR, C-13 NMR and P-31 NMR techniques. The fluorescence sensing performance of prepared water soluble tripodal systems were evaluated by UV/Vis and fluorescence spectroscopies. According to obtained results, two novel water-soluble sensing platfor...
Transformation pathways and fate of engineered nanoparticles (ENPs) in distinct interactive environmental compartments: A review
Abbas, Qumber; Yousaf, Balal; Amina, Amina; Ali, Muhammad Ubaid; Munir, Mehr Ahmed Mujtaba; El-Naggar, Ali; Rinklebe, Joerg; Naushad, Mu (Elsevier BV, 2020-05-01)
The ever increasing production and use of nano-enabled commercial products release the massive amount of engineered nanoparticles (ENPs) in the environment. An increasing number of recent studies have shown the toxic effects of ENPs on different organisms, raising concerns over the nano-pollutants behavior and fate in the various environmental compartments. After the release of ENPs in the environment, ENPs interact with various components of the environment and undergoes dynamic transformation processes. T...
Effect of d-psicose substitution on gelatin based soft candies: A TD-NMR study
Pocan, Pelin; İlhan, Esmanur; Öztop, Halil Mecit (Wiley, 2019-09-01)
Confectionary gels are considered as composite gel systems composed of high amount of sugar and gelling agent such as gelatin or starch. d-Psicose is classified as a type of rare sugar, which is a C-3 epimer of fructose and has 70% of the sweetness of sucrose with a caloric value of 0.39 kcal/g. Utilization of d-psicose in food products is gaining particular interest due to its low caloric value. In this study, gelatin-based soft candies were formulated, and the effect of d-psicose substitution was explored...
