The special mechanical properties of nanoparticles allow for novel applications in many fields, e.g., surface engineering, tribology and nanomanufacturing/nanofabrication. In this review, the basic physics relevant interfacial forces to main measuring techniques are briefly introduced first. Then, theories important results between or acting on a surface, hardness, elastic modulus, adhesion friction, as well movement laws surveyed. Afterwards, several result their properties, including...
We directly configured double-walled carbon nanotubes as energy conversion materials to fabricate thin-film solar cells, with serving both photogeneration sites and a charge carriers collecting/transport layer. The cells consist of semitransparent thin film conformally coated on n-type crystalline silicon substrate create high-density p−n heterojunctions between n-Si favor separation extract electrons (through n-Si) holes nanotubes). Initial tests have shown power efficiency >1%, proving...
Superlubricity of graphite and graphene has aroused increasing interest in recent years. Yet how to obtain a long-lasting superlubricity between layers, under high applied normal load ambient atmosphere still remains challenge but is highly desirable.

The exceptionally low...
Abstract Hydrogenated amorphous carbon (a-C:H) is capable of providing a near-frictionless lubrication state when rubbed in dry sliding contacts. Nevertheless, the mechanisms governing superlubricity a-C:H are still not well comprehended, mainly due to lack spatially resolved structural information buried contact surface. Here, we present analysis carbonaceous interfaces at atomic scale two superlubricious solid lubricants, and Si-doped (a-C:H:Si), by probing area using state-of-the-art...

Abstract In modern electric equipment, especially vehicles, inverter control systems can lead to complex shaft voltages and bearing currents. Within an motor, many parts have electrical failure problems, among which bearings are the most sensitive vulnerable components. recent years, failures in been frequently reported of has become a key issue that restricts lifetime all-electric motor-based power broader sense. The purpose this review is provide comprehensive overview premature mechanical...
Graphene has been recognized as an excellent lubrication material owing to its two-dimensional structure and weak interlayer interactions. However, most extant works concerning superlubricity involving graphene oxide have limited nanoscale or microscale dimensions (of the order of 1-10 μm). In present work, realization a robust macroscale state (μ = 0.0037), by taking advantage synergy effect graphene-oxide nanoflakes (GONFs) ethanediol (EDO) at Si3N4-SiO2 interfaces is reported. GONFs...
Though fluorescence-tag-based anti-counterfeiting technology has distinguished itself with cost-effective features and huge information loading capacity, the clonable decryption process of spatial-resolved cannot meet requirements for high-security-level anti-counterfeiting.
