N-Vacancy-Functionalized Carbon for High-Rate Li-Ion Storage.

Although heteroatom doping and pore management separately influence the Li adsorption and Li diffusion properties, respectively, merging their functions into a single unit is intriguing and has not been fully investigated. Herein, we have successfully incorporated both heteroatom doping and pore management within the same functional unit of N-vacancy motifs, which is realized via acid etching of formamide-derived Zn-N-functionalized carbon materials (ZnNC). The N-vacancy-rich porous carbon (V-NC) renders multiple merits: (1) a high N content of 13.

Formamide-derived "glue" for the hundred-gram scale synthesis of atomically dispersed iron-nitrogen-carbon electrocatalysts.

The distinct structure and maximum utilization of metal atoms on supported single-atom catalysts (SACs) represents a new frontier of heterogeneous catalysis, yet the low-cost mass production of high-performance SACs is still a key issue for practical applications. Herein, by coating a formamide-derived highly N-modified carbonaceous layer as a "glue" on commercially available activated carbon black (AC), a hundred-gram scale synthesis of atomically dispersed non-noble metal-nitrogen-carbon (MNC) materials was realized, including but not limited to Fe, Co, Ni, Mn, and Cu. The dispersion and coordination environments of Fe atoms on AC were initially revealed by XRD, HRTEM, and XPS, and further confirmed by HAADF-STEM and XANES analysis, presenting Fe atoms in a Fe-N structure.

Construction of high-density genetic map and QTL mapping of yield-related and two quality traits in soybean RILs population by RAD-sequencing.

Background: One of the overarching goals of soybean breeding is to develop lines that combine increased yield with improved quality characteristics. High-density-marker QTL mapping can serve as an effective strategy to identify novel genomic information to facilitate crop improvement. In this study, we genotyped a recombinant inbred line (RIL) population (Zhonghuang 24 × Huaxia 3) using a restriction-site associated DNA sequencing (RAD-seq) approach.

[Reconstruction of vertebral lamina with skull titanium plate and autograft in the treatment of thoracolumbar vertebral fracture].

Objective: To discuss the surgical skill, treatment effect and indications for reconstruction of vertebral lamina with skull titanium plate and autograft in the treatment of thoracolumbar vertebrae fracture.

Methods: From March 1999 to April 2007, 33 patients with thoracolumbar vertebrae fracture combined nerve injury were treated by reconstruction of vertebral lamina with skull titanium plate and autograft including 30 males and 3 females with an average age of 41 years ranging from 21 to 66. The fracture involved 3 cases in T11, 9 in T12, 16 in L1, 3 in L2 and 2 in L3.
