Electrochemically assisted photocatalysis on self-organized
investigate influence of an externally applied bias on the photocatalytic performance of self-organized TiO2 nanotubelayers. These layers were grown by anodization of titanium in fluoride containing electrolytes and have different geometric dimensions.
the working electrodes are irradiated by the UVlight with total duration of 1 h using He–Cd laser (intensity50 mW cm2, 325 nm, Kimmon Electric, Japan) with thelaser beam expanded by a lens to approx.
One-step holographic grating inscription in polymers
In this study severalcopolymers with MethylMethAcrylate as base material with different crosslinkers and initiators are compared.Unlike commercially available PMMA, the polymers have a glass transition temperature up to 155 ◦C, whichenables the use on hig
Gratings were inscribed using a Lloyd-mirror setup and the well-known phase mask method. For both inscriptionsetups a Kimmon HeCd-Laser Model 5552R-F emitting at 325 nm was used to modify the polymers. The UVbeamof the HeCd-Laser has 10 cm coherence len
Photoluminescence of Graphene Oxide Infiltrated into Mesoporous
aGO−porous silicon (GO−PSi) hybrid structure is realized in order to investigate theemission properties of GO infiltrated into a porous matrix. GO−PSi is characterized byFourier transform infrared spectroscopy, spectroscopic reflectometry, and steady-stat
Steady-statephotoluminescence (PL) spectra were excited by a continuouswave He−Cd laser at 442 nm (KIMMON Laser System). PLwas collected at normal incidence to the surface of samplesthrough a fiber, dispersed in a spectrometer (PrincetonInstruments, Spect
The Heme-Binding Component of the Microprocessor Complex
DGCR8 is the RNA binding partner of the nuclease Drosha. Their complex (the“Microprocessor”) is essential for processing of long, primary microRNAs (pri-miRNAs) in thenucleus. Heme binding to DGCR8 is essential for pri-miRNA processing.
The ferric DGCR8 samples weremeasured with the 441.6 nm excitation line from a He-Cd laser (IK Series He-Cd laser, KimmonKoha Co. Ltd., CO), while the ferrous DGCR8 sample was measured with the 415 nm lineprovided by a Kr+ laser (Coherent Innova Sabre Ion
Lloyd’s mirror interferometer using a single-mode fiber spatial filter
An ultraviolet single-mode fiber is used for beam transport, spatial filtering, and beam expansionfor a Lloyd’s mirror interferometer for laser interference lithography. Polarized laser light at325 nm from a HeCd laser was coupled to a nonpolarization-mai
The laser beam was produced by a 50-mW rated HeCd laser operating at a wavelength of325 nm (Kimmon Koha, IK3501R-G). The beam diameterwas approximately 1.2mm 1=e2 intensity.
