A bioprinting approach that utilizes organoid-forming stem cells as a living ink within hydrogels guides tissue-scale self-organization to generate more realistic gastrointestinal and vascular tissue constructs.
Colloidal structures and lattices made of patchy particles with chemically distinct lobes are formed by exploring site-specific depletion forces. This approach introduces a simple route to assemble colloidal superlattices.
A dose threshold of one trillion nanoparticles in mice has been discovered and is shown to be crucial for overwhelming the nanoparticle uptake kinetics of liver Kupffer cells and for ensuring efficient nanoparticle delivery into solid tumours upon intravenous administration.
Surface ledges of β-Ga2O3 (100) substrates guide the unidirectional nucleation and growth of transition metal dichalcogenides, achieving centimetre-long, single-crystalline and densely aligned nanoribbons in wafer scale.
Non-fullerene acceptors have successfully overcome energy losses that were thought to be unavoidable in organic solar cells based on fullerene derivatives. However, it is now shown that they have limits too.
Single crystals and thin films of metal–organic frameworks can now be directly patterned by lithography down to the sub-50-nm scale, enabling straightforward integration in solid-state devices.
In situ metabolic labelling and targeted modulation of dendritic cells has been achieved using a hydrogel system in combination with covalent capture of antigens and adjuvants, facilitating improved tumour-specific immune response.
Light is known to induce segregation of iodine and bromine in mixed-halide perovskites. Counterintuitively, it is now shown that irradiation at higher intensity reverses this process, leading to halide remixing.
Zeolitic catalyst particles are grown with nanosized fins that improve mass transport into the interior of the particle. This delays catalyst deactivation in the methanol-to-hydrocarbons process.
Polymeric glasses with significant thermodynamic and kinetic stability have been fabricated using physical vapour deposition, providing a mean to gather insight into the properties of glasses aged for millions of years.
Controlling nuclear spins coupled to an electron spin in silicon carbide has enabled development of a ‘quantum register’ interfaced with telecom photons, leading to the possibility of distant transport of quantum information.
Correlated real-space imaging and optical measurements of twisted MoSe2/WSe2 bilayers reveal strain-induced modulations of the moiré potential landscape, tuning arrays of 0D traps into 1D stripes and leading to substantial changes in the optical response of the heterostructures.
Carbon nanotubes with single-digit diameter embedded in a solid artificial membrane show pressure-sensitive ionic conductance that is similar to the mechanically activated currents of biological ion channels.
The discovery of intrinsic quantum confinement effects in the form of oscillations in the optical absorption of formamidinium lead triiodide thin films is a vivid example of the surprising physical properties of these hybrid organic–inorganic materials.
Functional single-cell liver hemi-canaliculi have been generated in a synthetic microenvironment using a reductionist approach. It is shown that the interaction between the extracellular matrix and static cadherin is sufficient to develop an apicobasal polarity independently of the contact with neighbouring cells.
