The availability of two-dimensional (2-D) dopant profiling techniques to Silicon Carbide (SiC) pn junction is discussed. We compared the results of scanning capacitance microscopy (SCM), scanning spreading resistance microscopy (SSRM), and secondary electron microscopy (SEM), where the cross-sections of a SiC wafer with n-type epi-layers and highly-doped p and n regions were used. The SSRM curr...

Seven commercial titanium dioxide pigments and two other well-defined TiO2 materials (TiMs) were physicochemically characterised using asymmetric flow field flow fractionation (aF4) for separation, various techniques to determine size distribution and inductively coupled plasma mass spectrometry (ICPMS) for chemical characterization. The aF4-ICPMS conditions were optimised and validated for lin...

Palynologists use compound light microscopy (LM) for pollen identification and interpretation and scanning electron microscopy (SEM) for morphological comparisons and taxonomy. As we are unaware of any published reports comparing LM and SEM pollen counts and identifications of the same sample, we decided to examine a surface soil sample using both microscopes. Standard palynological extraction ...

Cell surfaces interface with a variety of environments and, as a consequence, cell surface properties are of considerable functional importance to the biological organism. SEM immunocytochemistry (SEM-IC) is one of a range of techniques used to analyse cell surface properties. A major goal of SEM-IC centres on extended survey or high-magnification morphological analysis of cell and tissue surfa...

Causal relations are present in many application domains. Causal Probabilistic Logic (CP-logic) is a probabilistic modeling language that is especially designed to express such relations. This paper investigates the learning of CP-logic theories (CP-theories) from training data. Its first contribution is SEM-CP-logic, an algorithm that learns CP-theories by leveraging Bayesian network (BN) lear...

Dental microwear analyses are among the most significant techniques though which a researcher can make dietary and ecological inferences from primate fossil specimens. Hard particles, such as plant phytoliths or silica-base sands, can scratch tooth enamel surfaces during food mastication producing a dietary specific pattern of microwear on the enamel surface. The density, axis length and orient...

Introduction “Second best no more” was the title of an article written by David C. Joy for Nature Materials [1]. The article was for highlighting a breakthrough made by a team formed between Brookhaven National Laboratory (BNL, USA) and Hitachi High Technologies Corporation (HHT, Japan). Sub-angstrom secondary electron (SE) images were obtained on a Hitachi HD-2700, which is a combined scanning...
