High resolution imaging by secondary ion mass spectrometry and atom probe tomography have been employed to investigate boron segregation at austenite grain boundaries (γ GBs) after soaking in a high-strength low-carbon steel. The combined use of these two analytical techniques is shown to be powerful for quantifying solute and segregated boron leve...
This dissertation details the utilization of anionic, nucleophilic iron complexes supported by m-terphenyl isocyanide and carbonyl ligands to address longstanding questions in organometallic and inorganic chemistry. Chapter 1 offers a brief account of the development of low valent transition-metal chemistry with carbon monoxide (CO) and isocyanides...
In this study, the powder-pack boriding process on low-carbon stainless steel was carried out at 1273 K for 4 h of exposure to obtain a layer around ~57 μm conformed by FeB, Fe2B, and others alloying elements. Firstly, the presence of iron borides formed on the surface of borided AISI 316L alloy was confirmed by optical microscopy combined with the...

As highly efficient non-precious metal-based catalysts for the hydrogen evolution reaction (HER), the molybdenum carbides have attracted much attention over the phase and structure modification for the improvement of HER performances. In this work, a novel strategy is proposed to modulate phases of molybdenum carbides by boron doping, so that the H...

A series of Be3B3+ and its rare gas (Rg) containing complexes RgnBe3B3+ (Rg = He–Rn, n = 1–6) have been predicted theoretically using the B3LYP, MP2, and CCSD(T) methods to explore structures, stability, charge distributions, and nature of bonding. Both Be3B3+ and RgBe3B3+ are the global minima on the potential energy surfaces. In the RgnBe3B3+ com...

The amino acid derivative 4-borono- L -phenylalanine (BPA) has been used in the radiation medicine technique boron neutron capture therapy (BNCT). Here we have characterized its interaction with DNA when incorporated into a positively charged hexa- L -arginine peptide. This ligand binds strongly to DNA and induces its condensation, an effect which ...

In the present article we describe the creation of a small carboranylcarboxamide compound library followed by a screening campaign at the soluble epoxide hydrolase (sEH). We identified meta-carboranyl alkylamides, -anilides, and -benzylamides as potent sEH inhibitors. Furthermore, we optimized the scaffolds and we derived structure-activity relatio...
The RNA World hypothesis requires the synthesis of RNA to allow the emergence of life on Earth. Hydrothermal systems have been proposed as potential candidates for constructing complex biomolecules. However, in order to successfully form RNA, it is necessary to stabilize ribose, a RNA carbohydrate component. Borate has been found to stabilize ribos...

The contamination risks by naturally derived toxic elements must be assessed to achieve a sustainable geo-environment when utilizing excavated surplus soils. To estimate the controlling factors and risks of groundwater pollution associating with the application of recycled excavated surplus soils, the sequentially extracted fractions of major and t...
