Sealed nanofluidic channels with cross sections of sub-100 nm * 100 nm were created in a polymer bilayer using the focused soft X-rays of a scanning transmission X-ray microscope and the direct write method. The width of the nanochannels can be controlled by the area patterned in X and Y, while the height can be controlled by tuning the layer thicknesses. Formation of the desired structures has...

X-Ray absorption spectromicroscopy provides rich information on the chemical organization of materials down to the nanoscale. However, interpretation of this information in studies of "natural" materials such as biological or environmental science specimens can be complicated by the complex mixtures of spectroscopically complicated materials present. We describe here the shortcomings that somet...

Abstract The Jahn–Teller (JT) effect, through geometric deformation of molecules or local ionic lattices, lowers the overall energy system by removing electron degeneracy from partially occupied orbitals. Crystal symmetry lowered JT distortion inevitably creates multiple variants elastic and orbital-anisotropic states. Visualization control domain/wall textures create a cornerstone to understan...

Chemical and structural modifications occurring in homogeneous crystalline Si nanoparticles (NPs) used as anode material Li cells are investigated. State‐of‐the‐art high‐resolution scanning transmission electron microscopy coupled with energy loss spectroscopy resolved at the nanoscale is exploited. It directly highlighted by spectromicroscopy that, above 0.1 V versus Li, electrochemical activi...

Scanning transmission X-ray microscopy (STXM) was utilized for analysing the bioremediation of Cr(VI) by Citrobacter freundii, a species gram-negative bacteria. The biosorption and bioreduction processes were analysed chemical mapping cells biosorbed at different concentrations Cr(VI). STXM spectromicroscopy images recorded O K-edge Cr L-edge. A thorough analysis absorption features correspondi...
