A JEOL-JSM-7001F SEM and JEOL 2100 field emission gun TEM were used to examine the morphology. AC HAADF-STEM images and EDS elemental mappings were carried out by a Cs-corrected FEI Titan G2 60-300 equipped with a Super-X EDS detector and operated at 300 kV. Chemical compositions and elemental oxidation states were checked by XPS spectra (PHI-5702). X-ray absorption spectra (XANES and EXAFS) of W L3- and Mo K-edges were measured on VESPERS beamline at the Canadian Light Source, by scanning a double-crystal Si(111) monochromator and collecting emitted x-ray fluorescence.

Trophozoites treated with 100% C. sinensis were harvested, fixed, and dehydrated using a graded series of ethanol as described below for TEM. After dehydration, critical point drying was performed by infiltrating the samples in hexamethyldisilazane (HMDS) (Acros, Germany) for 5 min twice to further enhance drying of the samples. The samples were mounted on aluminium SEM stubs with a double-sided carbon sticker and sputter coated with gold prior to SEM imaging.

The starting sample used in this study was a typical MQW LED structure consisting of layers in the order from top to bottom: a 0.2 μm p-type GaN:Mg top layer, then 5 periods of In0.2Ga0.8N/GaN MQWs with barrier’s (well’s) thickness of 30 nm (3 nm), and a 3.0 μm n-type GaN:Si buffer bottom layer, which was grown on c-plane sapphire with metalorganic chemical vapor deposition. The nanowires were prepared with the “top-down” dry etching process using Ni self-assembled nanoislands as the etching mask. Other preparation details of the NWs can be referred to a publication24 .
A JEOL (JSM-7001F) SEM microscopy was employed to characterize the dimensions of the nanopillars. Micro-Raman scattering spectra were measured on an integrated WITec Alpha scanning confocal micro-Raman system with the back-scattering geometric configuration14 . In the Raman scattering measurements, the 514.5 nm line of an argon ion gas laser was used as the excitation source. Variable-temperature PL spectral measurements were carried out on a home-made PL system using a Kimmon 325 nm He-Cd laser as the excitation light source. The maximum output power of the He-Cd laser was 38 mW. In the PL measurements, the samples were mounted on the cold figure of a Janis closed cycle cryostat proving a varying temperature range of 3.6–300 K. A detailed description of the PL setup can be referred to a previous publication25 .

While Pelargonium endlicherianum Pelargonium quercetorum LM . The polar and equatorial axis, colpus length and width, and exine and intine thickness of the pollen were measured 30 times. The morphological characteristics under the LM were measured using an Olympus BX41 microscope. Microphotographs were taken from this microscope’s camera. During SEM , selected dry samples of pollens were placed on the aluminum stabs with the help of double-sided adhesive tape and coated in gold with a vacuum.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
