Advanced Characterization of Materials for Superconducting Radiofrequency Accelerator Cavities
… Both are pursued by materials modification: nitrogen doping/infusion in the first instance and coating with Nb3Sn in the second. Materials characterization is key to achieving understanding and directing RandD. However, very little has been done. This present work aims to fill the knowledge …

RECYCLING OF WASTE BLOOD INTO FUNCTIONAL CARBON NANOPARTICLES
… confirmed HDs’ carbon-based structure, nitrogen-doping, and size distribution (average diameter of 8 nm), with properties resembling commercial carbon dots. In vitro tests demonstrated HDs’ dose-dependent anticoagulant effects, reducing clot formation with minimal impact on blood …

Defect engineering of cuprous oxide thin-films for photovoltaic applications
… of Cu 20-based solar cells. First, nitrogen doping is proposed as an effective p-type doping method to control optical and electrical properties of Cu₂O thin-films. The film's p-type conductivity is elucidated by temperature-dependent Hall effect measurements and a compensated …

Trace Level Impurity Quantitation and the Reduction of Calibration Uncertainty for Secondary Ion Mass Spectrometry Analysis of Niobium Superconducting Radio Frequency Materials
… high accelerating gradients. The discovery of "nitrogen doping" was the first readily accessible avenue of interstitial alloying in which researchers saw an increase in cavity performance. However, the serendipitous nature of the discovery led to additional research to fundamentally understand …

Highly Conductive Ultrananocrystalline Diamond Thin Films via Nitrogen Incorporation
… a highly conductive, n-type diamond film via nitrogen doping. Ultrananocrystalline diamond (UNCD) films with up to 0.2% total nitrogen content were synthesized by a microwave plasma-enhanced chemical-vapordeposition method using a CH4/Ar gas mixture with added nitrogen gas. The electrical …

Nanostructured Metal Oxide Coatings for Electrochemical Energy Conversion and Storage Electrodes
… a better understanding of how the effects of nitrogen doping via NH3 annealing treatments, used to reduce TiO2’s bandgap, can have a strong dependence on TiO2’s thickness and crystalline quality. In addition, it was found that some of the negative effects on the PEC performance typically …

Non-Precious Metal-Based Electrocatalysts from Prussian Blue Analogues for Energy-Related Reaction
… to Ir/C. Detailed studies prove that the nitrogen doping, a discrete graphitic shell, and a mesoporous structure work in harmony to enhance the OER performance. Exploring efficient bifunctional electrocatalysts for ORR and OER remains significant for metal-air battery progress. At second …

Heteroatom-Doped Graphitic Materials for Energy Storage
… material. In Chapter 2, investigations into nitrogen-doping are made. Alterations to the synthetic procedure in combination with thorough structural and compositional analysis helps in understanding what factors make nitrogen-doped graphite effective as an anode. Notably, it was found that …

Correlation of Photocatalytic Activity with Band Structure of Low-dimensional Semiconductor Nanostructures
… by dopants, these results give insight into why doping is not always beneficial to the overall photocatalytic performance despite increases in absorption. Second, we improved the photocatalytic performance of two-dimensional lanthanum titanate (La2Ti2 O7) nanosheets, which are widely studied as …
