Biodegradable, perfusable scaffolds are able to generate both in vitro cardiac and hepatic vascularized tissue models and in vivo implants for direct surgical anastomosis.
Ultrashort pulses of X-rays from a free-electron laser capture the spatiotemporal evolution of spins in the different crystallographic directions of a complex magnetic material.
A regenerative cardiac patch with integrated freestanding electrodes allows the electrical stimulation and recording of cardiomyocyte growth and activity, with on-demand drug delivery.
Laser-generated exciton–polariton condensates in transition metal dichalcogenide heterostructures may trigger Cooper pairing of electrons and induce high-temperature superconductivity.
The dynamics of the magnetic correlations after photo-doping Sr2IrO4 are studied through ultrafast time-resolved resonant inelastic X-ray spectroscopy. The timescales are found to depend on the dimensionality of the correlations.
Photocatalytic water splitting using semiconductors is attractive for converting solar energy into hydrogen. An efficient and scalable system based on particulate photocatalyst sheets is now shown to exhibit energy conversion efficiency exceeding 1%.
Resonant soft X-ray scattering characterization of the cuprate superconductors La1.875Ba0.125CuO4 and YBa2Cu3O6.67 shows that the orbital symmetry of the charge density waves is a key feature determining their properties.
A highly sensitive plasmonic biosensor, based on hyperbolic metamaterials, can detect biomolecules of ultralow molecular weight at picomolar concentrations.
By diluting conjugated polymers in high-bandgap host matrices it is shown that electron trapping effects can be significantly reduced. This approach is used to fabricate polymer LEDs with enhanced efficiency and reduced fabrication costs.
One-dimensional linear carbon chains reaching a length close to 800 nm have been synthesized at high temperature and high vacuum using double-walled carbon nanotubes as nanoreactors.
Molybdenum sulfides are attractive electrocatalysts for the hydrogen evolution reaction. The polymeric structure of amorphous molybdenum sulfide can now be formulated as a coordination polymer based on [Mo3S132−] clusters sharing disulfide ligands.
Soft biomimetic microswimmers and microrobots made of photoactive liquid-crystal elastomers and whose body shape is controlled by structured light are able to self-propel and perform complex motion patterns on demand.
Designed DNA-based polyhedral frames, whose vertices are connected to nanoparticles, facilitate their self-assembly into predetermined crystalline and open three-dimensional lattices.
