Two-dimensional poly(arylene vinylene) frameworks are promising polymer semiconductors, yet obtaining highly crystalline materials is a major challenge. Now a series of 11 highly crystalline or single-crystalline 2D poly(arylene vinylene)s have been prepared—from 2D imine-linked covalent organic frameworks through a Mannich-elimination strategy—with diverse lattices, enhanced conjugation and specific surface areas up to 2,000 m² g⁻¹.

Molecular doping is essential for optimizing carrier concentration, charge mobility, and energy levels of organic semiconductors, but efficient n(electron)-type doping remains challenging. Here, the authors present a catalysed n-doping strategy using air-stable, cost-effective, and commercially available soluble organometallic complexes.

A global research network monitoring the Amazon for 30 years reports in this study that tree size increased by 3% each decade.

The benchmark fullerene-based electron-transporting materials (ETMs) for inverted perovskite solar cells are often limited by thermal evaporation or stability issues. Here the authors report solution-processable non-fullerene ETMs with improved device stability and efficiency.

Pentagonal PdSe₂ induces anisotropic, gate-tunable spin–orbit coupling in graphene, enabling a tenfold modulation of in-plane spin lifetimes at room temperature and providing opportunities to control spin dynamics in van der Waals materials.

A genome-wide study by the Long COVID Host Genetics Initiative identifies an association between the FOXP4 locus and long COVID, implicating altered lung function in its pathophysiology.

The spin accumulation in graphene can be enhanced by a thermal gradient as a result of a thermoelectric spin voltage owing to an effective spin-dependent Seebeck coefficient.

Magnons are quanta of spin-wave excitations and are likely to play a major role in the physical mechanisms of combining spin and heat transport. Now, a new device that enables the properties of magnons to be measured independently of the thermoelectric contribution of electrons and phonons is shown, providing crucial information for understanding the physics of electron–magnon interactions, magnon dynamics and thermal spin transport.

Studying the spin lifetime anisotropy in graphene, which provides information on spin-orbit interaction and is relevant to spintronic applications, poses important experimental challenges. Here, the authors study the spin lifetime anisotropy using spin precession under oblique magnetic fields.

Enhanced spin-charge conversion in graphene is realized by proximity coupling to WS₂ and electric-field tunability is demonstrated.

Spin relaxation in graphene is much faster than theoretically expected. Now, a scenario based on a mixing of spin and pseudospin degrees of freedom and defect-induced spatial spin–orbit coupling variations predicts longer spin relaxation times.

The secretome from cancer and stromal cells contributes to the creation of a microenvironment, which in turn contributes to invasion and angiogenesis. Here, the authors compare the secretomes of immortalized normal fibroblasts and cancer-derived fibroblast and identify CLIC3 as a driver of cancer progression.

Large spin–orbit coupling can be induced when graphene interfaces with semiconducting transition metal dichalcogenides, leading to strongly anisotropic spin dynamics. As a result, orientation-dependent spin relaxation is observed.

Artificial atoms, quantum systems with atom-like energy structure, have been studied with frequency spectroscopic techniques. However, much information about the energy level spectrum has been hidden, as the technique is impractical for high frequencies. A complementary technique has been developed where the energy level of an artificial atom is not scanned by tuning frequency, but amplitude of the radiation, while the frequency is tuned to a specific feature in the spectrum.

The magnetic phase diagram of thin-layered antiferromagnets is revealed experimentally by investigating the tunnelling conductance as a function of magnetic field. A rich magnetic behaviour in CrCl₃ is uncovered, from which relevant magnetic information is extracted that is not easily available with other approaches.

Electron tunnelling through a two-dimensional magnetic insulator is assisted by magnon inelastic processes that provide spin-filtering.

The preparation of a diverse set of 2D materials and their co-integration in van der Waals heterostructures enable innovative material design and device engineering. This Review summarizes recent advances in 2D spintronics and opto-spintronics, the underlying physical concepts and future perspectives of the field.

Developments, challenges and opportunities in using two-dimensional materials for the next generation of non-volatile spin-based memory technologies are reviewed, and possible disruptive improvements are discussed.

This Review Article examines the potential of spintronics in four key areas of application —memories, sensors, microwave devices, and logic devices — and discusses the challenges that need be addressed in order to integrate spintronic materials and functionalities into mainstream microelectronic platforms.

Community microattribution review of the evidence for colon cancer risk conferred by constitutional variants in MLH1, MSH2, MSH6 and PMS2 has resulted in the reclassification of two-thirds of the variants reported in existing databases and led to clinical recommendations for the interpretation of 1,370 variants that do not result in obvious protein truncation.
