Abstract Mechanoluminescent (ML) materials that directly convert mechanical energy into photon emission have emerged as promising candidates for various applications. Despite the recent advances in development of both novel and conventional ML materials, limited access to simultaneously attributes high brightness, low cost, self‐recovery, stability, lack appropriate designs constructing devices represent significant challenges remain be addressed boost practical application materials....
Abstract Mechanoluminescence is a smart light‐emitting phenomenon in which applied mechanical energy directly converted into photon emissions. In particular, mechanoluminescent materials have shown considerable potential for applications the fields of and sensing. This study thoroughly investigates mechanoluminescence long afterglow properties singly doped codoped Sr 2 MgSi O 7 (SMSO) with varying concentrations Eu 2+ Dy 3+ ions. Subsequently, comprehensive analysis its multimode...
In hydrothermal ores, gold is commonly hosted by sulfide minerals due to its affinity for reduced sulfur. contrast, the occurrence of in oxide remains poorly documented and incompletely understood. this contribution, we demonstrate that magnetite can be a significant host mineral gold. Skarn ores from giant Beiya Au deposit (323 t at 2.47 g/t), southwest China, contain abundant nanometer- micronsized magnetite. A range bismuth (e.g., native bismuth, maldonite, bismuthinite) occur within same...
Abstract Deep-sea sediments rich in rare earth elements and yttrium (REY) are promising mineral resources that believed to be associated with the burial of fish debris. However, nature REY enrichment is poorly understood, part due a lack robust age constraints. We report bioapatite U-Pb ages from an Ocean Drilling Program (Leg 199, Hole 1218A) core REY-rich sedimentary Pacific Ocean, which yielded ranging 22.8 18.2 Ma 6.5 2.2 Ma, respectively. The teeth 1218A consistent biostratigraphic...
A new electronic speckle pattern interferometry method is proposed to realize in situ deformation measurements. The feature of the combination a high-speed camera and multiple laser Doppler vibrometers (LDVs) for synchronous used record select effective interferograms, while LDVs are measure rigid body displacement caused by vibrations. series interferograms with known shifted phase values obtained calculate phase. experimental results show that performs well measuring static dynamic...
Deep-sea REY (lanthanides and yttrium) can be initially scavenged by nano ferromanganese (oxyhydr)oxides via ion adsorption lattice substitution, while subsequent aging partial recrystallization induced reduction during diagenesis usually cause release redistribution of REY. Previous studies find positive correlations among REY, goethite (α-FeOOH) phosphorus/phosphate in some marine (micro)nodules, but the mechanism responsible for these is yet unclear. The interaction between iron...
A method for whole-field noncontact measurement of displacement, velocity, and acceleration a vibrating object based on image-plane digital holography is presented. series holograms are captured by use high-speed CCD camera. The result the reconstruction three-dimensional complex-valued matrix with noise. We apply Fourier analysis windowed in both spatial temporal domains to extract acceleration. instantaneous displacement obtained unwrapping filtered phase map, whereas velocity evaluated...
A 20-point laser Doppler vibrometer with single photodetector is presented for noncontact dynamic measurement. 5×4 beam array various frequency shifts generated by a 1.55 μm distributed feedback and four acousto-optic devices, illuminating different points on vibrating objects. The reflected beams are coupled into single-mode fiber pigtailed collimator interfere reference beam. signal output from high-speed amplified then digitized analog-to-digital converter sampling rate of 1 gigasample...
Code virtualization is a highly sophisticated obfuscation technique adopted by malware authors to stay under the radar. However, increasing complexity of code also becomes "double-edged sword" for practical application. Due its performance limitations and compatibility problems, seldom used on an entire program. Rather, it mainly only safeguard key parts such as security checks encryption keys. Many techniques have been proposed reverse engineer virtualized code, but they share some common...
Digital Image Correlation (DIC) is a crucial noncontact full-field optical measurement method used in various fields. However, practical applications, DIC affected by systematic and random noises, leading to experimental resolutions lower than theoretical ones. In this study, we proposed laser Doppler vibrometer guided perform vibration measurements. 3D-DIC obtains sequence of out displacement field initially. A three-dimensional frequency domain collaborative filtering (3D-FDCF) that...
