A Comprehensive Evaluation of Mechanical, Thermal, and Antibacterial Properties of PLA/ZnO Nanoflower Biocomposite Filaments for 3D Printing Application.

Functionalities of 3D printing filaments have gained much attention owing to their properties for various applications in the last few years. Innovative biocomposite 3D printing filaments based on polylactic acid (PLA) composited with ZnO nanoflowers at varying contents were successfully fabricated via a single-screw extrusion technique. The effects of the varying ZnO nanoflower contents on their chemical, thermal, mechanical, and antibacterial properties were investigated using Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and tensile testing, as well as qualitative and quantitative antibacterial tests, respectively.

Poly[tris-(μ-4,4'-bi-pyridine-κ(2) N:N')bis(dimethyl sulfoxide-κO)tetra-kis-(thiocyanato-κN)dicobalt(II)].

The asymmetric unit of the title compound, [Co2(NCS)4(C10H8N2)3(C2H6OS)2] n , consists of one Co(II) atom, two thio-cyanate anions, one dimethyl sulfoxide mol-ecule and one and a half 4,4'-bi-pyridine mol-ecules. The half-molecule is completed by inversion symmetry. The Co(II) atom is coordin-ated in a distorted octa-hedral geometry by two N atoms from two thio-cyanate anions, one O atom from dimethyl sulfoxide as a terminal ligand and three N atoms from three 4,4'-bi-pyridine mol-ecules as bridging ligands linking the cations, with a Co⋯Co separation of 11.

Catalytic properties of a series of coordination networks: cyanosilylation of aldehydes catalyzed by Zn(II)-4,4'-bpy-carboxylato complexes.

Three porous crystalline coordination polymers, i.e. the three-dimensional framework {[Zn(3)(4,4'-bpy)(3.

Five-coordinate copper(II) complexes: crystal structures, spectroscopic properties and new extended structural pathways of [Cu(chelate)2X]Y, where chelate = dpyam, phen and bipy; X = pseudohalide ligands.

The crystal structures of four distortion isomers of the [Cu(chelate)(2)X](+) cation, where chelate = 2,2-bipyridine (bipy), 1,10-phenanthroline (phen) and di-2-pyridylamine (dpyam), X = a pseudohalide ligand (NCO, NCS, N(3) and C(2)N(3)), have been compared by scatterplot analysis with 25 [Cu(chelate)(2)X]Y complexes of known crystal structure. The four new complexes [Cu(phen)(2)NCO]Br (1), [Cu(phen)(2)N(3)]BPh(4).H(2)O (2), [Cu(dpyam)(2)(N(3))]NO(3).
