Maskless Fabrication of Film-Patterned-Retarder (FPR) Using Wedged Liquid Crystal Cell by Doyeon Lee, Keumcheol Kwak, Chul Gyu Jhun, Hyun Seok Choi, Jang-kun Song

“…When the polarized monochromatic laser beam (450 nm) passes through the cell, periodically undulated polarization pattern of light is obtained, and can be used to produce FPR by combining with the photo-alignment method. The method does not require the expensive photomask and nano-wire grid polarizer, and the pitch of FPR can be simply controllable by changing the birefringence of LC material with temperature or using a light source of different wavelengths. …”

Numerical simulation of flow fields and permeability evolution in real fractures under continuous loading stress by LIANG Yunpei, ZHANG Huaijun, WANG Lichun, QIN Chaozhong, TIAN Jian, CHEN Qiang, SHI Bowen

“…The findings are significant: ① The 25 mm×50 mm real fracture in Brazilian splitting shows obvious heterogeneity in the microstructure of the original aperture and surface roughness, which is obviously different from the fracture that reaches the average scale directly generated by numerical method. ② In the process of stress loading, the fracture aperture, contact area and spatial correlation length show different evolution characteristics in the x direction and y direction due to the fracture heterogeneity, and the control mechanism of permeability change is different; ③ When the traditional empirical formula is used to fit the stress-sensitive permeability evolution of fracture, the deviation of the fitting degree increases with the increase of the heterogeneity of fracture samples. …”

Controlled biopolymer roughness induced by plasma and excimer laser treatment by P. Slepicka, I. Michaljanicova, V. Svorcik

“…The ablation loss and morphology of PLLA was induced by excimer laser exposure of plasma pre-treated PLLA with different laser fluencies and number of pulses. The combination of a certain input parameters of plasma pre-treatment together with laser exposure induces extensive physico-chemical changes (morphology, contact angle, optical properties) on polymer surface with dramatic roughness increase. …”
