Phosphorescence shows great potential for application in bioimaging and ion detection because of its long-lived luminescence high signal-to-noise ratio, but establishing phosphorescence emission aqueous environments remains a challenge. Herein, we present general design strategy that effectively promotes by utilising water molecules to construct hydrogen-bonded networks between carbon dots (CDs) cyanuric acid (CA). Interestingly, not only cause no quenching also greatly enhance the emission....
Carbon dots (CDs) have various attractive properties and potential applications, but there is much less attention paid to their phosphorescent phenomenon mechanism. Herein, we prepared a kind of highly efficient CD-based material by subtle design method that incorporated N-doped CDs (NCDs) into composite matrices (the melting recrystallization urea biuret from the heating urea) one-pot treatment for mixture NCDs. Through systematic investigation, C═N bonds on surface NCDs can create new...
The second near-infrared window emission (1.0-1.7 μm, NIR-II) has received extensive attention with the advantages of negligible tissue scattering, reduced autofluorescence, and less background noise. Here a novel analysis platform based on quantum dots (QDs) for highly selective detection Zn2+ Cd2+ an enhanced NIR-II fluorescence is reported first time. We have developed facile two-step route to synthesize water-soluble Ag2S QDs, constituting green hydrothermal process followed surface...
Developing advanced thermal interface materials (TIMs) to bridge heat-generating chip and heat sink for constructing an efficient transfer is the key technology solve management issue of high-power semiconductor devices. Based on ultra-high basal-plane conductivity, graphene ideal candidate preparing high-performance TIMs, preferably form a vertically aligned structure so that consistent with direction TIM. However, actual interfacial efficiency currently reported TIMs far from satisfactory....
This is part II of a two-part paper involving the development an asymmetrical flow control method to widen operating range turbocharger centrifugal compressor with high-pressure ratio. A nonaxisymmetrical self-recirculation casing treatment (SRCT) as instance presented. Experimental and numerical methods were used investigate impact SRCT on surge point compressor. First, influence geometry symmetric performance was studied by means simulation. The key parameter found be distance from main...
Engine downsizing is a proven method for CO2 reduction in Internal Combustion (ICE). A turbocharger, which reclaims the energy from exhaust gas to boost intake air, can effectively improve power density of engine thus one key enablers achieve downsizing. Acknowledging its importance, many research efforts have gone into improving turbocharger performance, includes turbine volute. The cross-section design volute usually compromise between level packaging and desired performance. Thus, it...
This is Part I of a two-part paper documenting the development novel asymmetric flow control method to improve stability high-pressure-ratio turbocharger centrifugal compressor. focuses on nonaxisymmetrical in compressor induced by geometry volute while II describes an avoid stall basis characteristic flow. To understand asymmetries, experimental measurements and corresponding numerical simulation were carried out. The static pressure was measured probes at different circumferential...
Once two-dimensional boron-based materials were forecasted, their excellent physical and chemical properties have realized attractive application value in the field of science. However, borophene could not exist independently stably nature. Molecular beam epitaxy is only way being used currently for preparation borophene, which has low yield harsh experimental installation conditions. Here, we propose theory that few-layer supported by silver nanoparticles can large-scale be performed...
Abstract The Nb 2 CT x prepared by hydrothermal-assisted in-situ HF generation etching was investigated in terms of its gas sensor performance. obtained mixing AlC with pure water, hydrochloric acid, and fluoride (LiF or NH 4 F) then hydrothermally treated at 180 °C for 24 h. This hydrothermal treatment more efficient safer the synthesis than direct etching. etched LiF had relatively wide interlayer spacing because hydration radius Li + larger that . results also suggest O 5 is formed during...
This study investigates the unsteady shear flow patterns and their relation with aerodynamic instability of a shrouded supercritical carbon dioxide (SCO2) centrifugal compressor impeller using dynamic mode decomposition method combined detached eddy simulation. The results demonstrate that discrete shedding vortex array in blade tip region is dominant SCO2 impeller, frequency 0.5 times passing frequency. In contrast, main structures identical ideal air consist small-scale vortices near...
