Localization of metabolites using multiplexed mass spectrometry imaging (MSI) provides important chemical information for biological research. In contrast to matrix-assisted laser desorption/ionization (MALDI), TiO2-assisted laser desorption/ionization (LDI) for MSI improves detection of low molecular mass metabolites (<500 Da) by reducing matrix background. However, the low UV absorption of Ti...

In the laser cutting process some well-known parameters, e.g. laser power and cutting speed, play major roles in the performance of the process. Each parameter or a combination of parameters can affect the material removal volume and cutting volume efficiency. The purpose of this research is to study the effect of power and maximum cutting speed on the material removal rate (MRR) and cutting vo...

Thermally-assisted ultra-fast magnetization reversal in a DC magnetic field for magnetic multilayer thin films with perpendicular anisotropy has been investigated in the time domain using femtosecond laser heating. The experiment is set-up as an optically pumped stroboscopic Time Resolved Magneto-Optical Kerr Effect magnetometer. It is observed that a modest laser fluence of about 0.3 mJ/cm ind...

Abstract We have investigated photon-assisted trapping and detrapping of electrons injected from the gate under negative bias in a heterostructure field-effect transistor (HFET). The electron injection rate was found to be dramatically affected by sub-bandgap laser illumination. trapped reduced two-dimensional gas (2DEG) density at AlGaN/GaN heterointerface but could also emitted their trap sta...

In this article, we present our study on surface plasmon SP assisted contact scheme nanoscale photolithography technique. Sub-100-nm features on a metallic mask, fabricated by e-beam lithography, were successfully transferred to a resist pattern in a setup close to traditional photolithography. Our previous work based on finite difference time domain simulation reveals the mechanism of SP-light...

ABSTRACT The performance of porous silicon and cobalt glancing angle deposited (GLAD) thin films for matrix-free laser desorption/ionization-MS analysis of carbohydrates, peptides and drugs with molecular weights < 2,500 Dalton is presented. The performance of these films for selected peptides and small drugs detection is similar to the best reported for desorption/ionization on electrochemical...

in this review collected from the literature on usage of laser in oral minor surgery based on a medline search in the time period between the years: 2008 and 2013, the most current evidence on laser-assisted oral minor surgery is going to be surveyed.
