Terahertz Spectroscopic Analysis of Lactose in Infant Formula: Implications for Detection and Quantification.

Lactose plays a significant role in daily lives as a constituent of various food and pharmaceutical products. Yet, lactose intolerance conditions demand low-lactose and lactose-free products in the market. These increasing nutritional claims and labels on food products entail simple and reliable methods of analysis that can be used for meeting quality standards, nutritional claims and legal requirements.

Influence of swift heavy ion irradiation on the photoluminescence of Si-nanoparticles and defects in SiO.

The influence of swift heavy ion (SHI) irradiation on the photoluminescence (PL) of silicon nanoparticles (SiNPs) and defects in SiO-film is investigated. SiNPs were formed by implantation of 70 keV Si and subsequent thermal annealing to produce optically active SiNPs and to remove implantation-induced defects. Seven different ion species with energy between 3-36 MeV and fluence from 10-10 cm were employed for irradiation of the implanted samples prior to the thermal annealing.
