Summary: This study investigated a new method for accurately estimating hydrogen content within specimen in atom probe tomography experiments. The research showed a highly correlated relationship between field evaporation rate and hydrogen content, leading to a new method for measuring hydrogen content. By combining extrapolation technique with continuous cycling of the evaporation rate during APT experiments, spatially resolved imaging of hydrogen concentrations could be achieved without the need for deuteration.

Summary: This study demonstrates the applicability of image analysis in analyzing and defining reservoir rock properties. Digital image techniques reveal the micro and macro-pore types and their connectivity across multiple scales. The study shows that porosity and permeability can be accurately evaluated using digital image analysis and statistical equations can be developed to understand the relationship between these parameters. The study highlights the importance of thresholding in evaluating porosity using digital images. The developed methodology can accurately characterize reservoirs based on pore networks using high-resolution imaging techniques.

Summary: A major aim in structural cell biology is to analyze intact cells in three dimensions, visualize subcellular structures, and even localize proteins at the best possible resolution in three dimensions. Recently developed electron microscopy tools offer great resolution in three dimensions, but the challenge is to investigate smaller volumes. Different approaches, including array tomography, batch tomography, and scanning transmission electron tomography, were presented at the Microscopy Conference in Vienna in 2021 to overcome this challenge and provide increased 3D information.

Summary: Farnesol showed concentration-dependent effects on cancer cell lines, reducing proliferation at certain doses while inducing growth at higher concentrations. However, it did not suppress cellular growth in healthy cell lines. TEM analysis revealed autophagic and apoptotic findings in cancer cell lines treated with farnesol, while healthy cell lines exhibited normal findings. This study provides valuable information regarding farnesol's potential as an anti-cancer agent.

Summary: This study investigated the effect of different dose concentrations of PEGylated nanomaterials on the accelerated blood clearance (ABC) phenomenon. It showed that a higher dose concentration of PEG reduced the occurrence of ABC, and PEG-coated AuNPs mainly accumulated in the liver and spleen. Furthermore, the study found that the number of B lymphocytes in the spleen was affected by repeated doses of PEG-coated AuNPs. Therefore, dose optimization of PEG molecules is crucial for the development of effective nanomaterial-based drug delivery systems and to control the ABC phenomenon.

Summary: A primo node was observed on the lymph vessel of the vagina, surrounded by mesothelial cells providing positive immunoreactivity to NSE and VEGF. Different sized sinuses, floating cells, telocyte-like cell, and primo microcells were detected as the main constituents of the primo node, with migratory cells passing from the node to the lymph vessel.

Summary: Sub-sampling during image acquisition in STEM can increase the acquisition speed and control the dose effectively. Optimizing control parameters can improve the resolution, precision, and sensitivity of inpainted images. When combined with hardware for rapidly sub-sampling images in STEM, this approach has significant implications for imaging beam-sensitive materials and dynamic processes.
