Focused ion beam (FIB) techniques have been frequently used to section metal-halide perovskites for microstructural investigations. However, the beams directly irradiated sample surface may alter properties far different from pristine, potentially leading modified deterioration mechanisms under aging stressors. Here, we combine complementary approaches measure subsurface characteristics of poli...

The “Selva Central” of Peru is characterized by its forest species richness that produces quality wood for countless uses. Therefore, it necessary to identify the and macroscopic anatomy, which an important tool botanical identification tree species. For this purpose, 13 sawmills located in 3 provinces were selected exploit several Central”. Sampling representative woods was carried out, identi...

apart expressing the cause of the reflection of light from the surface of polished objects, ibn al-haytham in his al-manāẓir claims that the acceptance or rejection of light by these objects is only due to their polished surfaces and have nothing to do with their solidity, because the reflection of light from the surface of soft polished objects such as water is also possible. kamāl al-dīn al-f...

Introduction: Trapped noble gases were discovered in chon-drules by laser microprobe noble gas analysis [1-3]. The observed noble gases were explained by solar gas acquisition in dust grains before the chondrule formation [1-3]. These results show importance of trapped noble gases in chondrites to understand environment and formation processes of chondrules. We performed the laser microprobe no...
