Repair of spinal cord injury will require enhanced recruitment endogenous neural stem cells (NSCs) from the central canal region to lesion site reestablish connectivity. The strategy toward this goal is provide directional cues, e.g., alignment topography and biological gradients rostral caudal ends center. This study demonstrates a facile method for fabrication continuous stromal-cell-derived factor-1α (SDF1α) embedded in radially aligned electrospun collagen/poly (ε-caprolactone) mats....

While single-atom catalysts (SACs) have been extensively studied as a type of high-atom-efficiency heterogeneous catalyst, their reaction stability under high temperature reductive atmosphere is yet to be addressed. In this work, we introduced Co–O moiety Co–N–C SACs by employing glutamic acid both N,O-bidentate ligand Co(II) and source for N-doped carbon. After undergoing pyrolysis in N2 at 900 °C, the complex transformed into CoN3O1–OH2 structure subsequently CoN3O1 upon being submitted...

The Compressible Micro Interconnects (CMIs) in the Replaceable Integrated Chiplet (PINCH) assembly are key electrical components that compensate for height differences and nonuniform forces. This study develops a stochastic finite element model (SFEM) combining Monte Carlo sampling with analysis to evaluate mechanical reliability of CMIs. Geometrical material parameters treated as variables within specified ranges. FEM results show good agreement reported stress distributions, maximum Von...

The stochastic distributed placement of vacancy defects has evident effects on graphene mechanical property, which is a crucial and challenged issue in the field nanomaterial. Different from molecular dynamic theory continuum mechanics theory, Monte Carlo based finite element method (MC-FEM) was proposed performed to simulate vibration behavior defected graphene. Based simulation, difficulties random location were well overcome. beam chosen represent exact atomic lattice results MC-FEM have...

Nitrous oxide (N2O) is a greenhouse gas mainly produced during the denitrification process in treatment of wastewater, especially saline wastewater. N2O production increases with salinity. In this study, Halomonas sp. 3H was isolated from eutrophic lake sediment. It exhibited high saline–alkaline tolerance. The strain possessed complete-denitrification-related gene clusters (narIJHGXLK, nirSBD, norEDQBC, and nosLYFDZR). Under shaking at 150 rpm, it could completely remove ammonium nitrogen...

A new concentration series is proposed for the construction of a two-dimensional (2D) synchronous spectrum orthogonal sample design analysis to probe intermolecular interaction between solutes dissolved in same solutions. The obtained 2D possesses following two properties: (1) cross peaks spectra can be used reflect reliably, since interference portions that have nothing do with are completely removed, and (2) produced effectively avoid accidental collinearity. Hence, correct number nonzero...
