Two compounds were designed, synthesized, and characterized by 1H-nuclear magnetic resonance (1H-NMR), ultraviolet (UV)-visible, and matrix-assisted laser desorption/ionization (MALDI) mass spectra.
      
Restriction Enzyme Pattern Analysis of Mycobacteria DNA by Capillary Electrophoresis with Laser-Induced Fluorescence Detection
      
A new method for rapidly detecting restriction enzyme patterns of Mycobacterium DNA using capillary electrophoresis with laser-induced fluorescence detection (CE-LIFD) was developed.
      
The polymers were characterized by IR spectra, thermal-weight analysis, scanning electron microscope and laser particle size analysis.
      
Photoinduced intramolecular electron transfer process from C60 moiety to carbazole moiety has been studied by nanosecond laser flash photolysis.
      
Nanocarbon-poly(methyl methacrylate) sols were prepared by pulsed laser ablation at the interface of target submerged in flowing liquid (PLA-IT/SFL) method, and the corresponding composite films were prepared by solution-casting.
      
Affinity labeling coupled with matrix assistant laser desorption tandem time of flight mass spectrometry for quantitative proteo
      
A relative quantitative method for differential proteomics by cleavable isotope-coded affinity tag (cICAT) and matrix-assisted laser desorption/ionization tandem timeof-flight mass spectrometry (MALDI-TOF-MS) was established.
      
Laser Particle Size Analyzer measured the particle distributions in the dissolution of cinnabar.
      
The composite latex particles and composite materials were determined and characterized using a laser particle size analyzer, transmission electron microscopy or scanning electron microscopy.
      
Analysis and experiment on deformation of sheet metal by laser shock wave
      
The mechanism of laser shock deformation and the reason for the production of the shockwave are introduced.
      
An evaluation formula of the detonation wave pressure in the system of laser, energy transferring-medium and sheet metal is built according to the theory of detonation wave and blasting gas-dynamics.
      
The minimal energy of the laser pulse is evaluated on the basis of the formula of the laser shock pressure and evaluation of dynamic yielding strength.
      
The result shows that the quantity of sheet metal deforming is nonlinearly increased with laser energy, i.e., pressure of the laser shock wave.
      
Under a laser-induced ultra-high pressure and high strain rate, structural steels and composite materials undergo plastic deformation.
      
Laser vision sensing based on adaptive welding for aluminum alloy
      
A laser vision sensing based on the adaptive tungsten inert gas (TIG) welding system for large-scale aluminum alloy components was established to fit various weld groove conditions.
      
A new type of laser vision sensor was used to precisely measure the weld groove.
