Electron beam radiation improves bond strength of UV adhesives
摘要： State-of-the-art adhesives are often a smart solution for bonding medical technology products. Certified medical grade adhesives are biocompatible, produce permanent, reliable and durable bonds and are resistant to the standard sterilisation methods. Causing additional polymerisation, electron beam (E-beam) sterilisation even improves the adhesion coefficients.

Novel in-situ radiation construction of thioglycollic acid capped CdS quantum dots functionalized g-C3N4 nanohybrids with superior photocatalytic activity under visible light
摘要： A novel type of thioglycollic acid (TGA) capped CdS QDs functionalized g-C3N4 nanohybrids was prepared successfully by in-situ electron beam radiation at room temperature. When the radiation dose was chosen to be 10 kGy, the concentration of CdCl2 was 0.5 mmol/L and the optimum ratio of TGA to CdCl2 was 3 : 1 at pH = 9.0, the TGA-CdS QDs/g-C3N4 nanohydrids had the highest degradation rate at the modified TGA-CdS QDs content of 3.0 wt % and the removal rate of TGA-CdS QDs/g-C3N4 on the dye of MO was reached 94.7% in less than 20 min. The introduction of TGA-CdS QDs was confirmed successfully by a series of morphologies and structures of characterization and analysis with UV–vis, FL, Inverted-FL, DRS, FTIR, XRD, XPS, FE-SEM and HR-TEM, etc. After the introduction of TGA-CdS QDs into the surfaces of g-C3N4, the recombination of photo-generated electron-hole pairs can be significantly reduced and the photocatalytic activity and photostability can be also improved. It is favorable to enhance the photocatalytic performance for the photo-generated holes are rapidly transferred to the solution and hindered the photo-corrosion of TGA-CdS QDs.

An Overview of the Synthesis of Gold Nanoparticles Using Radiation Technologies
摘要： At a nano-level, optical properties of gold are unique and gave birth to an emerging platform of nanogold-based systems for diverse applications, because gold nanoparticle properties are tunable as a function of size and shape. Within the available techniques for the synthesis of gold nanoparticles, the radiolytic synthesis allows proper control of the nucleation process without the need for reducing agents, in a single step, combined or not with simultaneous sterilization. This review details and summarizes the use of radiation technologies for the synthesis and preparation of gold nanoparticles concerning fundamental aspects, mechanism, current pathways for synthesis and radiation sources, as well as briefly outlines final applications and some toxicity aspects related to nanogold-based systems.
