In this study, the evolution of the dislocation cell structure and variation of mechanical properties of structural steel under low-cycle fatigue were studied using the indentation experiment, optical microscope, and transmission electron microscope examinations. The results indicated that the dislocation cell structure was well-formed under cyclic loading.

Petrified wood samples are found within terrestrial sediments belonging to the Late Oligocene-Early Miocene Danişmen Formation in Malkara-Keşan located in the southwest of the Thrace Basin. The petrified wood in both regions is usually silicified and partly coalified. The silicification of the Tertiary wood in the Malkara-Keşan region is associated with volcanic activity and coeval sedimentation. Thin sections from petrified wood samples were taken as transverse, tangential, and radial sections.

In this study we extracted bioactive ingredients from fruiting bodies of Laetiporus sulphureus with different solvents and tested the antimicrobial and antitumor activities. The predominant lipid composition of the fruiting bodies was studied with GC–MS and revealed a high amount of oleic acid, octadecenoic acid and ergosterol derivatives.

In this paper "Nanostructured poly (3-octyl thiophene) films prepared by electrophoretic deposition", the preparation and properties of the nanoparticles of poly (3-octyl thiophene) (marked as P3OT) were presented. The EPD was adopted to prepare the polymer films. The properties of material were study by Raman, UV-Vis spectra, electron scanning microscopy (SEM), cyclic voltammetry (CV) and photocurrent measurements.

This study also showed comparatively higher solubility percentage in ‘BARI TPS-1’ tuber than the other local varieties, suggesting rapid disruption of swollen starch granule and faster starch degradation in TPS than the other local potato starches. Scanning Electron Microscope (SEM) images of starch granule showed rapidly ruptured and clumped starch granules in ‘BARI-TPS-1’ than the others, indicating TPS starch might obtain gelatinization temperature within a shorter period of microwave heating than that of the other varieties.

Though thermoelectric effect which enables to convert directly heat into electricity has been investigated long time ago, its practical applications have been still few due to the low efficiency. Material science focuses on developing the area to increase the performance is still under investigation.

In recent years, optical orthogonal frequency division multiplexing (OOFDM) has emerged as a dominant research and development area in the field of high-speed optical communications. OFDM is a potential candidate as the most promising next-generation optical networks such as passive optical networks and optical transport networks, due to their simple configuration based on low cost, high speed data rates, high spectral efficiency, high quality of service and robustness against narrow band interference, frequency selective fading, and chromatic dispersion.
