Book Part Citation - Scopus: 12Green electrospinning(De Gruyter, 2019) Horzum,N.; Muñoz-Espí,R.; Hood,M.A.; Demir,M.M.; Crespy,D.In the last two decades, electrospinning has grown in popularity; however, the majority of the setups are based on solution processing from toxic organic solvents. As green processing and environmental stewardship have also become important in recent years, for political and economic reasons, the subsequent increase in demand for the scaling up of electrospinning requires that an environmentally toxin-free process be championed. This book comprehensively addresses clean and safe electrospinning for the fabrication of green nanofibers and evaluates their potential applications. © 2019 Walter de Gruyter GmbH, Berlin/Boston.

The increase in demand for scaling up electrospinning in recent years therefore requires an environmentally friendly process free of organic solvents. This book addresses techniques for clean and safe electrospinning in the fabrication of green nanofibers and their potential applications. © 2019 Walter de Gruyter GmbH, Berlin/Boston.

Green fibers are particularly interesting for biomedical applications such as tissue engineering, drug delivery, biocompatible scaffolds, biosensors, and for photovoltaics, supercapacitors, fuel cells, battery components as energy fields, and for filtration membranes as environmental applications. In this chapter, we classified green electrospinning into two groups: (i) green processes as polymer free, solvent free, solution, and colloid electrospinning, (ii) green fibers from natural polymers and blends. © 2019 Walter de Gruyter GmbH, Berlin/Boston.

One of the popular data structures used to represent large heterogeneous data in the field of data mining is graphs. So, graph mining is one of the most popular subdivisions of data mining. Subgraphs that are more frequently encountered than the user-defined threshold in a database are called frequent subgraphs. Frequent subgraphs in a database can give important information about this database. Using this information, data can be classified, clustered and indexed. The purpose of this survey is to examine frequent subgraph mining algorithms (i) in terms of frequent subgraph discovery process phases such as candidate generation and frequency calculation, (ii) categorize the algorithms according to their general attributes such as input type, dynamicity of graphs, result type, algorithmic approach they are based on, algorithmic design and graph representation as well as (iii) to discuss the performance of algorithms in comparison to each other and the challenges faced by the algorithms recently.Article A Quantitative Balian-Low Theorem for Higher Dimensions(De Gruyter, 2020) Temur, FarukWe extend the quantitative Balian-Low theorem of Nitzan and Olsen to higher dimensions. We use Zak transform methods and dimension reduction. The characterization of the Gabor-Riesz bases by the Zak transform allows us to reduce the problem to the quasiperiodicity and the boundedness from below of the Zak transforms of the Gabor-Riesz basis generators, two properties for which dimension reduction is possible. © 2018 Walter de Gruyter GmbH, Berlin/Boston 2018.Article Citation - WoS: 5Citation - Scopus: 6Oxo-Bridged (haloarylimido)[tris(3,5-Dimethylpyrazolyl)borato] Molybdenum(v) Complexes: Crystal Structures of Geometric Isomers of [motp*(o)cl](µ-O)[motp*(cl)(?nc6h 4br)](De Gruyter, 2005) Sözüer, Hikmet Işıl; Dülger İrdem, Seçkiner; Jeffery, John J.; Hamidov, Hayrullah; Şentürk, Ozan SanlıThe reaction between [MoTp*(O)Cl2], [Tp* = hydrotris(3,5-dimetylpyrazol-1-yl)borate] and 4-bromoaniline in refluxing toluene gave geometric isomers of [MoTp*(O)Cl](μ-O)[MoTp*(Cl) (≡NC6H4Br)] (1a, cis; 1b, trans), but a similar reaction between [MoTp*(O)Cl2] and 4-chloroaniline yielded only one product, [MoTp*(O)Cl](μ-O)[MoTp*(Cl)(≡NC 6H4Cl)] (2) as a red crystalline solid. The new compounds were characterized by microanalytical data, mass, IR and 1H NMR spectroscopy. The X-ray structure analysis of 1a and 1b revealed that the complexes are geometric isomers, the two chloro ligands being cis in 1a and trans in 1b. Both compounds have Mo-O-Mo linkages and nearly linear arylimido moieties.
