Abstract Ultralong organic phosphorescence (UOP) has attracted increasing attention due to its potential applications in optoelectronics, bioelectronics, and security protection. However, achieving UOP with high quantum efficiency (QE) over 20 % is still full of challenges intersystem crossing (ISC) fast non‐radiative transitions molecules. Here, we present a novel strategy enhance the QE materials by modulating intramolecular halogen bonding via structural isomerism. The CzS2Br reaches up...
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...
Several ionic liquids (ILs) are formed in situ with monovalent metal salts and ethylene glycol (EG). The macroscale superlubricity antiwear properties of the ILs were studied between ceramic materials. Superlow coefficients friction less than 0.01 could be obtained for all at silicon nitride (Si3N4) interfaces induced by tribochemical reactions. Notably, IL ([Li(EG)]PF6) LiPF6 EG exhibited greatest properties. results film thickness calculations surface analysis showed that lubrication...
Introduction of graphene-family nanoflakes in liquid results a reduction friction and enhanced wear resistance. However, the high demand for dispersity stability largely restricted choice thus far. This study proposed new strategy to overcome this limitation, involving formation graphene coating with deposited nanoflakes, followed by lubrication glycerol solution. Pristine (PG), fluorinated (FG), oxide (GO) were chosen be on respective SiO2 substrates form coatings, then an aqueous solution...
As a new two-dimensional (2D) material, black phosphorus (BP) exhibits great potential for friction reduction. However, achieving macroscale superlubricity with BP coating remains challenge. In this study, we designed lubrication system to achieve at the macroscale, involving formation of deposited nanoflakes, followed by water lubrication. Robust coefficient 0.001 can be achieved on in pure environment. The mechanism is mainly attributed shear-induced interfacial structural conversion...
Impairment of the inner blood-retinal barrier (iBRB) leads to various blinding diseases including diabetic retinopathy (DR). The cGAS-STING pathway has emerged as a driving force cardiovascular destruction, but its impact on neurovascular system is unclear. Here, we show that cGAMP, endogenous STING agonist, causes iBRB breakdown and retinal degeneration thorough P2RX7-mediated transport into microglia. Extracellular cGAMP were determined in tissue samples from patients with proliferative DR...
Boric acid is a weak and has been used as lubrication additive because of its special structure. In this study, we report that boric could achieve robust superlubricity (μ < 0.01) an in polyethylene glycol (PEG) aqueous solution at the Si3N4/SiO2 interfaces. The superlow steady friction coefficient approximately 0.004-0.006 be achieved with under neutral conditions (pH 6.4), which different from acidic leading to superlubricity. influence various factors, including concentration, sliding...

In thin-film lubrication (TFL), generally, the viscosity of lubricant and its coefficient friction (CoF) increase. Finding a method to reduce CoF in TFL is significant challenge for tribologists. present work, we report robust superlubricity attained by using polyalkylene glycols (PAGs, polar molecules) poly-α-olefins (PAOs, nonpolar as lubricants on steel/steel pairs that have been pre-treated wearing-in with polyethylene glycol aqueous solution (PEG(aq)). A steady state 0.0045 PAG100 0.006...
The robust liquid superlubricity of a room-temperature ionic induced by tribochemical reactions is explored in this study. Here, 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([EMIM]TFS) could realize stable (μ < 0.01) with water at the interfaces Si3N4/SiO2. A superlow and steady friction coefficient 0.002-0.004 be achieved under neutral conditions (pH 6.9 ± 0.1) after 600 s running-in process. Various factors that affect were explored, including concentration [EMIM]TFS, sliding...
Developing highly efficient red/near-infrared thermally activated delayed fluorescence (TADF) materials is of great importance for organic light-emitting diodes (OLEDs). Here, we reported an asymmetric TADF emitter (TCPQ), which exhibits a high reverse intersystem crossing rate as well low non-radiative due to molecular symmetry breaking through multiple donor substitution. The coexistence donors endows TCPQ with not only near-infrared emission but also excellent device performances. As the...
Abstract Graphene-oxide (GO) has been recognized as an excellent lubrication material owing to its two-dimensional structure and weak interlayer interactions. However, the functional groups of GO that can contribute anti-friction, anti-wear, superlubricity are yet be elucidated. Hence, further improvement in GO-family materials tribology fields is impeded. In this study, macroscale with a coefficient friction less than 0.01 achieved by exploiting high adhesive force between amino within...
