Interfaces are essential in electrochemical processes, providing a critical nanoscopic design feature for composite electrodes used in Li-ion batteries. Understanding the structure, wetting and mobility at nano-confined interfaces is important for improving the efficiency and lifetime of electrochemical devices. Here we use a Surface Forces Apparatus to quantify the initial wetting of nanometre...

Transparent glasses in a system of Li2O-MgO-SiO2-Al2O3-Fchemical constituents were prepared by melt quenching method. In the fabrication of nanocrystal glass-ceramics, controlled nucleation and subsequent crystal growth were necessary to avoid loss of transparency. It was therefore important to understand thermal properties and crystallization kinetic...

MHC-I type chain-related protein A (MICA) is a newly discovered transmembrane glycoprotein encoded by MHC genes. MICA mainly functions as natural killer (NK) cells, cytotoxic T lymphocytes (CTLs), and other immune effector cell activation receptor NKG2D ligands. These ligands can bind NKG2D-specific proteins, transmit activation signals, induce immune effector cells to clear rapidly the tumor c...

Abstract New experiments on the strongly peraluminous, Li-, P- and F-rich Beauvoir granite (Massif Central, France) provide a basis for understanding crystallization chemical fractionation in Variscan rare metal magmas. Crystallization were performed two natural compositions under H2O-saturated conditions at 100, 200, 300 MPa, from 540°C to 700°C between ~NNO + 3 NNO-1.4. Experimental charges e...

The W–Sn Panasqueira ore deposit is a magmatic-hydrothermal system, which includes high-grade quartz-vein type mineralization and disseminated greisen-type occurring in the upper part of two-mica granite. We investigated genetic chronological relationships between greisenization granite formation ore-bearing quartz veins by monitoring major trace elements variations quartz-white mica assemblage...

Major histocompatibility complex class I-related chain A (MICA) is located at 46 kb centromeric of HLA-B. It is highly polymorphic and interacts with NKG2D, its receptor on the surface of NK, Tgammadelta and T CD8 lymphocytes. Data on MICA polymorphism in different populations are still limited. Our aim was to establish allelic diversity of MICA gene and linkage disequilibrium with HLA-B in our...

Even when kidney allografts are well matched for human leukocyte antigen (HLA) and anti-HLA antibodies are not detected, graft rejection can still occur. There is evidence that some patients who lose their graft have antibodies specific for major histocompatibility complex (MHC) class I-related chain A (MICA) antigens. We investigated whether mismatching MICA alleles associates with MICA antibo...
