This article studies the particle temperature distribution depending on the laser radiation power and the particle’s trajectory and velocity. The uneven heating of particles moving in the laser radiation field is identified. The regimes of laser heating without melting, with partial melting, and with complete particle melting are considered.

The use of a conventional streak camera for subnanosecond timeresolved fluorimetry is extended to the single-photon counting regime by utilizing intensified readout of the phosphor. The system achieves the usual k e y advantages of photon counting, namely single-photon sensitivity, large dynamic range and shot noise limited statistics, but also permits measurements of lower repetition rate and ...

Development of sensitive enzymatic methods for hydrogen peroxide is key for the quantification of several bioconstituents such as glucose, triglycerides, creatinine, and uric acid and so on. Hydrogen peroxide released by the oxidase enzymes are quantified by peroxidase enzyme involving spectrophotometry, fluorimetry, chemiluminisence, potentiometric sensing, amperometric, coulometric and such o...

Differential scanning fluorimetry (DSF) is used to assess protein stability, transition states, or the Kd values of various ligands, drug molecules, and antibodies. All fluorescent probes published to date either are incompatible with hydrophobic proteins/ligands, precluding analyses of transmembrane or membrane-associated proteins, or have excitation and detection wavelengths outside the range...

Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...

Background and Aim: Previous studies revealed improved enamel caries resistance after laser irradiation. Present in vitro study evaluated the effect of Er,Cr:YSGG laser with or without topical fluoride application on microhardness of primary enamel after artificial demineralization. Materials and Methods: In this in vitro study, 35 primary molars with sound surfaces were bisected and randomly ...

Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to ...
