Molding technology is widely used to manufacture optical components because of its high efficiency. Along with the quick development of miniaturization in industry, the detrimental effects of previously negligible burrs and defects on mold surfaces have become significant to the performance of components, so these problems should be minimized. In this study, a laser assisted micromachining method was developed to solve this problem during the fabrication of periodic microstructures on a molding material of electroless nickel-phosphorus (NiP) plating. The transient temperature distributions of the workpiece under laser irradiation and the change in the maximum shear stress during the laser assisted micromachining process were simulated to set appropriate experimental conditions. Then, periodic micropyramid structures were fabricated by both conventional cutting and the laser assisted cutting processes. Results show that defects largely decreased on machined structures with the assistance of laser irradiation. The decrease in specific cutting force and the change of chips’ morphology were also utilized to analyze the reasons for this improvement.

The Impact

Nowadays, due to the mass production of plastic products, the question of the negative impact of bisphenol A on the functioning of organs and systems is acute. However, the question of the effect of this xenobiotic on the functional state of the kidneys remains open. Currently, laser irradiation of various powers is intensively used to correct pathologies. However, its biochemical feathers of the impact on biological objects require detailed research. The work is aimed at the study of nephrotoxic effects of bisphenol A under the conditions of irradiation of animals with a diode laser. ВРА was administered per os daily for 3 days at a dose of 50 mg/kg body weight, which corresponded with LOAEL dose. Irradiation was performed for 2 min with a low-diode laser λ = 650 nm (50 mW, 1.5 J/cm2 and 12.5 mW/cm2). The functional state of the kidneys was performed based on the determination of urea and creatinine content in urine and serum. The content of primary and secondary products of the LP was determined in the kidneys. It is shown, that the administration of bisphenol A is accompanied by a decrease in urea in serum and urine, an increase in serum creatinine and a decrease in this metabolite in urine, which may indicate impaired renal and hepatic function due to the damage of this organ by contaminants due to induction lipid oxidation. This is expressed by an increase in the content of conjugated diene and TBA-active compounds in the kidneys. At the same time, under the irradiation of animals, the concentration of urea and creatinine in the serum decreases compared with the BPA group, and in the urine, these indicators increase. Such results may indicate the normalization of kidney function due to the corrective action of the laser. Thus, the introduction of BPA is accompanied by the induction of LPS processes, which leads to renal dysfunction, and irradiation of animals has a corrective effect of nephrotoxic effects of BPA.

Copper Plasma

In a recent paper, Desai et al. (1994) have reported the observed characteristics of the specularly reflected laser light from a copper plasma created by laser irradiation of a planar copper target. They have measured specular reflection, and attributed the observed diffusivity of specularly reflected radiation to the curved and rippled surface at the radiation turning point in the plasma. The aim of this comment is to reanalyse the possible causes for the diffusion of specular reflection relevant to their experimental conditions.
