A method for simultaneous separation and determination of two coumarins,dicumarol and cyclocoumarol,in cosmetics by HPLC-diode-array detector(DAD) was developed.
Resonant absorption structure provides an effective method for designing and manufacturing microbridge resistor arrary with less power consumption and larger array.
The semiconductor laser arrays are applied almost in all photoelectronics fields, and becoming an important technique in optoelectronics science at present.
So the absorbing wavelength is selected,the operating condition optimized,and the quantitative and qualitative determination method on Polyoxin B by HPLC-DAD established.
To improve the robustness of the Minimum Variance Distortionless Response (MVDR) beamforming to the array steering vector, a quadratic constraint method is proposed.
A new fabrication method for hollow microneedle array is proposed with three times exposures in deep X-ray lithography of synchrotron radiation and the development procedure.
The microneedle array assembly can be mounted on planar or nonplanar surface or even on flexible objects,it also can be used for synthetic drugs,therapeutic proteins and vaccines.
Cynosural Generator Arrays provide a permanent cynosural beacon available to everyone in your alliance, which can be the target of capital ship jumps or jump portal links.
A hypercomplex model of acoustic vector sensor array is introduced.The hypercomplex number is used to model holistically the four output signal components of an acoustic vector sensor.
A minimally invasive reflective array, tool navigator, and a registered burr were used for localization and deroofing of the lesion, followed by curettage and highspeed burring of the cavity.
Incorporating array of metallic wires into the host media, such as ferrimagnet YIG under an external magnetic bias field, is a novel method to synthesize negative refractive index (NRI) material.
The coloring matter are separated by YWG-C18,the best wave is found by DAD detecter, the quantitative method is standard curve , the result is accurately ,the method are used simply.
