We have exfoliated hexagonal boron nitride by ultrasonication in solutions of polyvinylalcohol in water. The resultant nanosheets are sterically stabilised by adsorbed polymer chains. Centrifugation-based sizeselection was used to give dispersions of nanosheets with aspect ratio (length/thickness) of 1400. Such dispersions can be used to produce polyvinylalcohol–BN composite films. Helium ion m...

Most proteins must fold into precise three-dimensional conformations to fulfill their biological functions. Here we review recent concepts emerging from studies of protein folding in vitro and in vivo, with a focus on how proteins navigate the complex folding energy landscape inside cells with the aid of molecular chaperones. Understanding these reactions is also of considerable medical relevan...

Janus kinase (JAK) 2 plays a pivotal role in the tumorigenesis of signal transducers and activators of transcription (STAT) 3 constitutively activated solid tumors. JAK2mutations are involved in the pathogenesis of various types of hematopoietic disorders, such as myeloproliferative disorders, polycythemia vera, essential thrombocythemia, and primary myelofibrosis. Thus, small-molecular inhibit...

NATURE | VOL 411 | 31 MAY 2001 | www.nature.com 577 The circle shown in Fig. 3 shows an area where all three phases have been identi®ed in different runs. The centre of this circle is in excellent agreement with the g±b±perovskite+MgO triple point reported at 22.9 GPa and 2,260 K. The present data strongly support earlier estimates of the phaseboundary temperature between ringwoodite and perovs...
متن کاملHabitable planets around the star Gl 581 ?
Context. Thanks to remarkable progress, radial velocity surveys are now able to detect terrestrial planets at habitable distance from low-mass stars. Recently, two planets with minimum masses below 10 M⊕ were reported in a triple system around the M-type star Gliese 581. These planets are found at orbital distances comparable with the location of the boundaries of the habitable zone of their st...
