Counter-ion Dependent, LongitudinalUnzipping of Multi-Walled CarbonNanotubes to Highly Conductive andTransparent Graphene Nanoribbons
Here we report for the first time, a simple hydrothermal approach for the bulk production of highly conductive and transparent graphene nanoribbons (GNRs) using several counter ions from K2SO4, KNO3, KOH and H2SO4 in aqueous media, where, selective intercalation followed by exfoliation gives highly conducting GNRs wit…
Investigating quantum oscillations in the thermal coefficient of resistivity of ultra-thin Ag capping layers on Cu for ic interconnect applications
As the semiconductor industry continues to scale feature sizes, scattering from phonons, surfaces, and grain boundaries result in an increase of metal interconnect resistivity in state-of-the-art integrated circuits (ICs). The interconnect chapter of the 2011 International Technology Roadmap for Semiconductors (ITRS)…

A New Approach for Finite Element Analysis of SHCC Members
Strain hardening cementitious composites (SHCC) is often applied in practice for the control of surface cracking. For such applications, the crack opening, which depends on crack spacing, is an important design parameter. In conventional finite element analysis of members made with SHCC, elements are taken to follow a…

Functionomics of newly identified magnesiotropic genes
The recent improvements of next generation sequencing techniques allow relatively rapid and cheap identification of new gene mutations in patients with familial hypomagnesemia. Over the last years, many new genes are indentified that regulate Mg2+ reabsorption in the kidney. However, translating the genetic findings i…
GPa级超高压下Mg-6Zn-1Y合金凝固过程及准晶形成
采用FactSage热力学软件和镁基数据库计算了Mg-6Zn-1Y合金的凝固路径。利用SEM并配合EDS，XRD，DSC研究了超高压下Mg-6Zn-1Y合金的凝固过程和准晶形成。结果表明：常压下该合金凝固组织主要由粗大α-Mg枝晶和分布在枝晶间含准晶I-Mg3YZn6相的层片状组织等组成，合金凝固过程的实验分析与热力学计算结果吻合较好。Mg-6Zn-1Y合金在GPB级超高压下凝固不但可以获得超细的枝晶组织，还可改善枝晶间层片状组织的形态。随着凝固压力的增加，由常压下的晶间网状或带状逐渐过渡到超高压下的“长岛状”以及“粒状”。特别是提高了单位面积上晶间相（含准晶I-Mg3YZn6相）的含量，其体积分数约占40％，同时还形成了纳米级的…
Molecular and cellular basis of synovial joint formation
Synovial joints are the most common joints facilitating skeletal movement. Healthy articular cartilage in synovial joints provides a smooth, wear-resistant structure that reduces friction and absorbs impacts. These joints are encased in a joint capsule, with an outer layer of fibrous connective tissues and a synovial…
