Employing two benzoate derivatives with different numbers of non-coordinated fluoro-substituents, 2-fluorobenzoic acid (2-Hfba) and 2,6-difluorobenzoic (2,6-Hdfba), new azido-copper coordination polymers, [Cu(2-fba)(N3)(CH3OH)]n (1) [Cu(2,6-dfba)(N3)(CH3OH)]n (2), have been successfully isolated, then structurally magnetically investigated. Single crystal structure analysis demonstrates that the metal cations in resulting compounds are connected by alternating triple-bridge μ-1,1-azido,...

This paper systematically discusses the influence of temperature and humidity on adhesion performance underfill material (epoxy cured with acid anhydride), which was evaluated by die shear test after exposure to various conditions. The inherent strength between passivation is not affected significantly thermal cycling -55/spl deg/C 125/spl for 1000 cycles. decreases increase in investigated range, due decrease modulus temperature. A sharp occurs as increases toward glass transition material....
By elaborately employing a rigid tetrazo macrocyclic ligand, both the designed Co(II) complexes [Co(12-TMC)Py](BF4)2 (1) and [Co(12-TMC)DMF](BF4)Cl (2) (12-TMC = 1,4,7,10-tetramethyl-1,4,7,10-tetraazacyclododecane; Py pyridine; DMF N,N-dimethylformamide) adopt distorted square pyramidal geometry with identical equatorial site but flexible axial ligand environment. Such molecular design enables realization of field-induced single-ion magnets. Importantly, single-molecule magnets display...
Conductive polymer composites showing large positive temperature coefficient (PTC) are made of semi-crystalline as an insulator and a conducting filler, whose concentration is close to the critical volume fraction. In this study, resistivity PTC behavior high density polyethylene (HDPE) filled with different carbon blacks were studied. Among those composites, N660 black PE showed greatest behavior. Carbon particle size, small surface area amount aggregated structure leads amplitude...

Two isomeric Co(II) complexes with the same general molecular formula of [Co(napy)2(NO3)2] (napy = 1,8-naphthyridine) have been synthesized. X-ray single crystal structural determination demonstrates that two compounds exhibit highly irregular six- (1) and seven-coordinate (2) geometries, respectively. The magnetic measurements, X-band EPR data theoretical calculations were thoroughly investigated. Both show field-induced slow relaxation, which relaxation in 2 is attributed to an easy-plane...
Lane detection is an important and fundamental task in autonomous driving. Modern convolutional neural network (CNN) methods have achieved high performance lane detection; however, the intrinsic locality of convolution operations makes these limited effectively modeling long-range dependencies that are vital to capture global information lanes. Additionally, numerous result considerable computational cost for complexity. To overcome difficulties, we propose efficient method by combining CNN...
