A synchrotron X-ray diffraction experiment demonstrates an unexpected accumulation of electron density in the interlayer region of TiS2, and provides a benchmark for theoretical models of weak interlayer bonding.
Electron density in TiS2 is determined by synchrotron X-ray diffraction, which reveals significant differences between experimental data and theory for interlayer van der Waals interactions.
A systematic investigation of the spin relaxation in nitrogen vacancy centres in diamonds, induced by phononic vacuum modes at low temperature, reveals an upper limit of eight hours.
Understanding the structural stability of platinum surfaces upon oxidation and reduction conditions has proved challenging. A correlation of surface site formation to nanoisland growth in the electrochemical roughening of Pt(111) is now identified.
Sub-micrometre MOF particles are incorporated into polymers to form mixed matrix membranes. Molecular sieving enables performance far beyond current limits for two applications, butane isomer separation and combined CO2/H2S removal from natural gas.
The mechanism by which cell geometry regulates cell signalling is reported to be modulated by lipid rafts within the plasma membrane, which are now shown to be responsible for geometry-dependent mesenchymal stem cell differentiation.
By combining electron energy-loss magnetic chiral dichroism and chromatic-aberration-corrected transmission electron microscopy, it becomes possible to achieve atomic-scale imaging of magnetic circular dichroism.
A p-type metallic sheet forms between two oxide insulators, LaAlO3 and SrTiO3. Suppression of oxygen vacancies in SrTiO3 plays a critical role in forming this sheet.
An ionogram based on a layer-free nanotransistor reveals the ability to selectively measure target ions in serum. Experimental and theoretical assessment of the mechanism of the surface–ion interaction is also revealed.
A SrTiO3/LaAlO3/SrTiO3 heterostructure is fabricated in high oxygen partial pressure to prevent oxygen vacancy formation. Electrical transport and electron holography directly observes a highly mobile two dimensional hole gas at the top interface.
Molecular simulations reveal the self-assembly of small molecules into nanoparticle drug carriers. Targeting of colon and liver cancer cells by the nanoparticles via kinase inhibitors is employed in anti-tumour therapy in vivo.
This work reports a quantitative investigation of the interaction parameter and miscibility of donor and acceptor organic molecules and their relationship with the fill factor and photovoltaic performance of bulk-heterojunction organic solar cells.
Reconfigurable electronic devices that can be shaped in two or more stable geometries modifying their functionalities have been realized by engineering the sequence in which the elastomeric substrates are mechanically buckled.
An effective adjuvant for the induction of humoural and cellular immunity is achieved by a Pickering emulsion formulation that allows pliability and mobility of loaded antigens.
Art historians have joined forces with material scientists in order to better understand the objects of interest but also develop better conservation treatments and preservation approaches.
Carl Heron and Joanne Dyer from the British Museum in London talk to Nature Materials about the research activities at the museum and how scientists can impact cultural heritage.
Dye molecules are shown to assemble into J-aggregate arrays by sequence-specific organization in the minor groove of DNA duplex sequences. Energy transfer through these structures displays the hallmarks of coherent coupling over distances that exceed those of conventional dipole-coupling processes.
