Open AccessExponentially selective molecular sieving through angstrom pores
Two-dimensional crystals with angstrom-scale pores are widely considered as candidates for a next generation of molecular separation technologies aiming to provide extreme, exponentially large selectivity comb...

Capillary condensation under atomic-scale confinement
Capillary condensation of water is ubiquitous in nature and technology. It routinely occurs in granular and porous media, can strongly alter such properties as adhesion, lubrication, friction and corrosion, an...

Limits on gas impermeability of graphene
Despite being only one-atom thick, defect-free graphene is considered to be completely impermeable to all gases and liquids1–10. This conclusion is based on theory3–8 and supported by experiments1,9,10 that could...

Ballistic molecular transport through two-dimensional channels
Gas permeation through nanoscale pores is ubiquitous in nature and has an important role in many technologies1,2. Because the pore size is typically smaller than the mean free path of gas molecules, the flow of t...

Molecular transport through capillaries made with atomic-scale precision
Nanometre-scale graphitic capillaries with atomically flat walls are engineered and studied, revealing unexpectedly fast transport of liquid water through channels that accommodate only a few layers of water.

Open AccessTemperature-Dependent Asymmetry of Anisotropic Magnetoresistance in Silicon p-n Junctions
We report a large but asymmetric magnetoresistance in silicon p-n junctions, which contrasts with the fact of magnetoresistance being symmetric in magnetic metals and semiconductors. With temperature decreasing f...

Square ice in graphene nanocapillaries
The structure of the low-dimensional water confined in hydrophobic pores is shown, using electron microscopy and supported by molecular dynamics simulations, to be ‘square ice’, which does not have the convent...

Proton transport through one-atom-thick crystals
Measurements show that monolayers of graphene and hexagonal boron nitride are unexpectedly highly permeable to thermal protons and that their conductivity rapidly increases with temperature, but that no proton...

Glycogen Production from Glucose with Desoxycorticosterone and 11-Dehydro- 17-hydroxycorticosterone
IT is often said that the different corticosteroids have qualitatively different activities. Desoxycorticosterone is believed to act only on electrolyte metabolism, while 11-dehydro-17-hydroxycorticosterone (c...

Reversal of Glycogenetic to Glycogenolytic Action of Desoxycorticosterone in Rats
IT was shown in a series of papers from this Laboratory that desoxycorticosterone has in vitro, in the concentration of 1–5 mgm. per cent, an inhibitory effect on glycogen formation1– 4 of the isolated muscle, wh...
