The model of laser ablation driven by a bulk photothermal reaction is considered. Stationary wave solutions are obtained and analyzed. In the case of a simple photothermal bond-breaking reaction, it is possible to reduce this bulk ablation model to the surface evaporation model with some apparent activation energy. A more complicated model of laser ablation, taking into consideration a photothe...
Since malting process of barley is greatly affected by the seed endosperm structure, getting information about its anatomical characteristics along with physico-chemical properties would be very important. The aim of this study was to measure length, width, thickness, kernel density, bulk density, porosity, total nitrogen, reducing sugar, diastatic activity, pH and color changes during malting ...

We present a comparative study aiming at comprehending the effect of ultraviolet/ozone treatment on the modification of poly(dimethyl siloxane) (PDMS) and poly(vinylmethyl siloxane) (PVMS) silicone elastomers networks (SENs). Both PDMS and PVMS SENs undergo dramatic changes in their properties when exposed to UVO. The surface chemical composition of both PDMS and PVMS at long UVO treatment time...
Biodegradable porous polyurethanes scaffold have themselves opportunities in service, including controlled degradation rate, no-toxic degradation products. However, polyurethanes are lack of bioactive groups, which limits their application. This review gives the common modification methods, surface functionalization and blending modification. In finally, the review puts forward to the bulk modi...
To improve the biocompatibility of implants, surface medication is a common practice. Depending on the surface medication process, the physical and/or chemical properties of the surface are altered, keeping the bulk properties same. The flexibility and wide application potential of laser as a surface modification tool gives it certain advantages over the traditional physical and chemical proces...
