Films and patterns of 3D-oriented metal-organic frameworks (MOFs) afford well-ordered pore structures extending across centimeter-scale areas. These macroscopic domains aligned pores are pivotal to enhance diffusion along specific pathways orient functional guests. The anisotropic properties emerging from this alignment beneficial for applications in ion conductivity photonics. However, the structure MOF films can rapidly degrade under humid acidic conditions. Thus, more durable 3D-ordered...
In this work, in-plane and through-plane thermal diffusivities conductivities of a freestanding sheet graphene nanoplatelets are determined using photothermal beam deflection spectrometry. Two experimental methods were employed in order to observe the effect load pressures on diffusivity conductivity materials. The was by use slope method supported new theoretical model, whereas frequency scan which obtained data processed with specifically developed least-squares processing algorithm. On...
Measurement of absorption coefficients transparent samples is important for their characterization and identification; however, it challenging to measure low values, e.g., 10−3–10−4 cm−1 with high accuracy. Here, we report a compact photothermal lateral shearing digital holographic device. It based on the thermal lens effect common-path, self-referencing microscope comprising glass plate, probe beam, CMOS camera. The change in phase distribution caused by temperature due light measured from...
A mode-mismatched thermal lens spectrometry (TLS) technique, in a pump–probe two-laser-beam configuration, was employed for the experimental determination of properties four selected well-characterized polyolefin homopolymer films. We investigated diffusivity (D) and conductivity (κ) high-density polyethylene, low-density linear polypropylene. also measured structural (i.e., average molecular weight, polydispersity index, branching number), along with rheological melting point, specific heat...

Co-doped Zinc selenide (ZnSe) is a promising material because of high photoluminescence efficiency and wide spectral range emission in the visible region. In this work, ZnSe Eu3+/Yb3+ co-doped crystals were grown by chemical vapour transport method. Photoluminescence optical measurements revealed effect trivalent rare earth ions on new lines with enhancement intensity. spectrum, some sharp intense observed that allow for possibility covering broad range. Moreover, measurement showed lower...
Photothermal lens spectrometry is a powerful optical detection technique that can be used to investigate biomolecules. In this work, for the first time our knowledge, photothermal was determination of nanomolar concentrations three distinct deoxyribonucleic acid (DNA) strands using methylene blue as labeling dye. Methylene interacts with phosphate groups DNA in lower concentrations. It observed phosphate-methylene interaction had no obvious effect on absorption and fluorescence spectra, but...
