    The Coulomb drag effect describes long-range electronic interactions between the charge carriers of two conducting channels separated by an insulating layer. Here, the authors report a graphene/MoS2 heterostructure which operates using the Coulomb drag effect with energy barrier and exhibits high carrier mobility and on/off current ratio at room temperature

    Refracting light waves can split at two different angles, a phenomenon called birefringence, whereas for reflected waves the incident and reflected angle are usually the same. Here, using time-resolved magneto-optical microscopy the authors report the bi-reflection of magnetic spin waves when hybridising with elastic waves.

    Spin-orbit torque driven oscillators, such as spin Hall oscillators, form a class of devices that are intensively studied due to potential practical applications in spintronics. Here, the authors modify the conventional ferromagnetic/nonmagnetic stack to include an additional ferromagnetic layer and leverage the giant magnetoresistance effect to enhance the direct conversion of an in-plane driving current into the microwave output signal.

    Optical clocks have many applications, from improved GNSS measurements to fundamental tests of general relativity, but their frequency stability is limited by quantum noise and the Dick effect. The authors present and demonstrate a method to estimate the phase of an optical clock laser beyond the laser coherence time that can be used to improve the stability of these devices for applications in metrology and the search for new physics.

    Controlling the positioning of spheroids in 3D during bioprinting is one of the main challenges hindering the scaffold-free fabrication of biologically-relevant tissues and organs. Here, the authors combine cutting edge aspiration-assisted freeform bioprinting of spheroids with self-healing yield-stress gels, obtaining precise positioning and self-assembly into 3D complex configurations.

    Optical methods are extensively used for tissue imaging in the biomedical sector but they are limited for deep tissue analysis due to massive losses by strong light scattering, which can be mitigated with the use of ultrasound. The authors present proof-of-concept experiments showing transient ultrasound waves transversal to the direction of propagation of laser light that can be used to waveguide in the bulk of the scattering medium to a depth of 90 mean free paths.

    Extensive theoretical and experimental efforts have been devoted to the effect of quantum criticality in our understanding of the physics of high-temperature superconductors and strongly correlated electron materials, yet it remains a puzzle in condensed matter physics. The authors report observations of a quantum criticality by investigating the non-Fermi liquid thermodynamics and transport behaviour in a non-superconducting iron pnictide.

    The lack of widely tunable single-mode lasers in the long-wavelength part of the mid-infrared region has hindered optical metrology of bending vibrational modes. Here, a continuous-wave nonlinear laser source with tunability from 12.1 to 14.8 μm, coupled with a frequency comb, is used to measure bending modes frequencies of carbon dioxide and benzene with accuracy down to 30 kHz.
