Tuning friction force and reducing wear by applying alternating electric current in conductive AFM experiments

Friction and wear cause widespread energy loss and damage. Here, the authors propose a strategy to reduce friction and wear through inducing dynamic electronic density redistribution via alternating electric current.

Spontaneous droplets gyrating via asymmetric self-splitting on heterogeneous surfaces

Controlling droplet impact and rebound behaviour can have applications in inkjet printing and self-cleaning. Here the authors show how a chemically-patterned surface with high-adhesive spirals surrounded by hydrophobic, low-adhesive regions leads to gyration behaviour of impacting droplets.

Robust ultra-low-friction state of graphene via moiré superlattice confinement

Two-dimensional materials show remarkable lubrication properties, yet chemical modifications may hinder such capabilities. Here, the authors show that when graphene is aligned on a Ge(111) substrate, ultra-low friction can be preserved even after graphene fluorination or oxidation.

Evolution of the flat band and the role of lattice relaxations in twisted bilayer graphene

By combining nano-spot angle-resolved photoemission spectroscopy and atomic force microscopy, the authors resolve the fine electronic structure of the flat band and remote bands of twisted bilayer graphene as the twist angle varies, revealing a spectral weight transfer between remote bands that is attributed to lattice relaxations.

The evolving quality of frictional contact with graphene

Atomistic simulations reproduce experimental observations of transient frictional strengthening of graphene on an amorphous silicon substrate, an effect which diminishes as the number of graphene layers increases.

Adhesion-dependent negative friction coefficient on chemically modified graphite at the nanoscale

Classically, friction is known to increase with increasing normal load. Scanning probe experiments now show that reversible local delamination of chemically modified graphite can lead to an enhancement in friction as the applied load decreases, resulting in an effectively negative friction coefficient.

Domino-like stacking order switching in twisted monolayer–multilayer graphene

The interface stacking order of twisted graphene can be actively flipped between locally stable states using a mechanical impulse, and this flipping propagates spontaneously through the network in a domino-like fashion.

Iced photochemical reduction to synthesize atomically dispersed metals by suppressing nanocrystal growth

Photochemical synthesis is a popular approach to fabricate metallic nanoparticles, however stabilizing individually-dispersed atoms by this method remains challenging. Here, the authors freeze their precursor solution prior to UV irradiation to obtain atomically-dispersed platinum catalysts with high electrocatalytic performance.

Optocapillarity-driven assembly and reconfiguration of liquid crystal polymer actuators

When floating at the air water interface, the shape of objects determines their capillary menisci and mutual interaction. Hu et al. show how dynamically changing shapes of liquid-crystal polymer actuators can be used to achieve optically controlled and reconfigurable assembly.

Dispersal from the Qinghai-Tibet plateau by a high-altitude butterfly is associated with rapid expansion and reorganization of its genome

The butterfly Parnassius glacialis experienced vast environmental transition when it dispersed out of the Qinghai-Tibet plateau. Here, the authors find that P. glacialis has an unusually large genome with rapid accumulation of transposable elements possibly facilitating its evolutionary adaptation.
