Ultrafast compressed imaging is promising for capturing a large number of frames and providing single-shot observations various unknown important transient scenes. However, this technique often compromises spatial resolution in order to capture ultrafast phenomena with larger frame numbers. In paper, high-channel spectral-temporal active recording (H-STAR) proposed, which achieves both femtosecond-level speed high by substantially increasing the channels. H-STAR can realize highest 101.6...
Abstract How bright the Moon is forms a simple but fundamental and important question. Although numerous efforts have been made to answer this question such as use of sophisticated electro-optical measurements suggestions for calibration sites, still debated. An in situ measurement with panel on surface crucial obtaining accurate absolute reflectance resolving debate. China’s Chang’E-3 (CE-3) “Yutu” rover accomplished type using Visible-Near Infrared Spectrometer (VNIS). The VNIS, which were...
In this paper, the tunable optical trapping dependence on wavelength of incident beam is theoretically investigated based numerical simulations. The Monte Carlo method taken into account for exploring characteristics such as average deviation and number distribution histogram nanoparticles. It revealed that both width depth potential well particles can be flexibly adjusted by tuning beam. addition, wavelengths deepest strongest stiffness at bottom are separated. These phenomena explained...
Methacrylated hyperbranched poly(amine ester)s as oligomers in radiation curing resins have a lower viscosity and higher cure speed.

Aims . Studies on high-resolution and high-precision laboratory reflectance spectra of the Moon have historically been restricted to analysis old Apollo samples (>3.0 Ga). In contrast, studies young lunar soils exclusively relied remote sensing spectra. this study, we present results a spectral investigation (~2.0 Ga) obtained by Chang’E-5 (CE-5) mission. Methods We analyzed surficial subsurface collected through scooped drilled sampling methods. The CE-5 were compared with those orbital...
Chang'E lunar microwave sounder (CELMS) data provide a potential way to understand the thermophysical features of shallow crust. In this study, four typical Copernican craters, including Copernicus, Aristarchus, Tycho, and Jackson, have been selected their brightness temperature <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$(T_{B})$</tex-math></inline-formula> performances are evaluated with CE-2 CELMS...
Abstract Basaltic volcanism is one of the most important geologic processes Moon. Research on thickness and volume late‐stage basalts Mare Imbrium helps better understand source lunar eruption styles. Based whether apparent flow fronts exist or not, within were divided into two groups, namely, Upper Eratosthenian (UEm) Lower (LEm). Employing topographic profile analysis method for UEm crater excavation technique LEm, we studied distribution in Imbrium. For units, their thicknesses estimated...
Abstract We know very well the Moon’s appearance in visible wavelengths. What Moon midinfrared (MIR) looks like is still a mystery. present detailed of MIR observed by high‐resolution geostationary satellite and reveal essence behind its appearance. The opposite to normal shows limb darkening. Both absolute relative brightness distribution lunar disk changes with solar incidence angle i . signatures are controlled both reflection emission surface. center‐to‐limb temperature variation across...
Abstract The volume FeO and TiO 2 abundances (FTAs) of lunar regolith can be more important for understanding the geological evolution Moon compared to optical gamma-ray results. In this paper, FTAs are retrieved with microwave sounder (CELMS) data from Chang’E-2 satellite using back propagation neural network (BPNN) method. Firstly, a three-layered BPNN five-dimensional input is constructed by taking nonlinearity into account. Then, brightness temperature ( T B ) surface slope set as inputs...
Plasmonic optical tweezers with a symmetry-tunable potential well were investigated based on heterogeneous model of nano-bowtie antennas made different noble substances. The typical metals Au and Ag are considered as plasmonic supporters for excitation hybrid modes in bowtie dimers. It is proposed that the trapping force around quantum dot exhibits symmetry-broken characteristics becomes increasingly asymmetrical increasing applied laser electric field. Here, it explained by dominant plasmon...
Space weathering is an important surface process that occurs on the Moon and other airless bodies, especially those have no magnetic field. The optical effects of Moon's space largely been investigated in laboratory for lunar samples analogues. However, duplication pristine regolith Earth not possible. Here we report from unique perspective "Yutu" rover, which was part theChang'e-3 (CE-3) mission, building our previous work. Measurement visually undisturbed uppermost as well locations...
Major elements such as Fe, Ti, Mg, Al, Ca, and Si play very important roles in understanding the origin evolution of Moon. Previous maps these major derived from orbital data are based on mosaic images or low-resolution Gamma ray data. The hue variations gaps among boundaries not conducive to geological studies. This paper aims produce seamless homogenous distribution using single-exposure image whole lunar disk obtained by China's high-resolution geostationary satellite, Gaofen-4, with a...
Abstract The diurnal variation and distribution of lunar surficial hydration (OH/H 2 O) is great significance for understanding the solar wind implantation water cycle on Moon. Lunar south pole an ideal place to study due large number repeat observations same region, which very limited in mid‐ or low‐latitudes. Here we showed clear 0.5‐hr interval at pole. band depth with local time exactly opposite temperature, indicating that changes sufficiently temperature. This relationship indicates...
The mineralogy of mare basalts reflects the chemical composition magma source, as well physical and environment rock's formation. It is significant for understanding thermal evolution Moon. In this study, spatial distribution lunar northern nearside was mapped using Moon Mineralogy Mapper (M3) data. study area, which an elongated mare, Mare Frigoris Imbrium, characterized into 27 units based on multi-source data, including spectrum, terrain, element abundance. We extracted 177 M3 spectra...
We investigate the structural, static magnetic and damping properties in two Mn-deficient Weyl semimetal Co-Mn-Ga (CMG) alloy films, i.e., Co 55 Mn 18 Ga 27 (CMG1) 50 32 (CMG2), which were epitaxially grown on MgO (001) substrates. CMG1 has a mixing phase of B 2 L 1 , larger saturation magnetization ( M s ∼ 760 emu/cm 3 ), stronger in-plane anisotropy. CMG2 an almost pure phase, smaller (∼ 330 negligible Time-resolved magneto-optical Kerr effect results unambiguously demonstrate obvious...
