  1. 1. Computational Studies on Homogeneous Water Oxidation Catalysts

    Författare :Ge Li; Mårten S. G. Ahlquist; Moyses Araujo; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Computational studies; homogeneous; water oxidation catalysts; ruthenium; iron; mechanisms; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. LÄS MER

  2. 2. Women's call for caring care : perspectives of Chinese women with gestational diabetes mellitus about beliefs, self-care behavior, quality of care and lived experience

  3. 3. Development and Application of Laser-Induced Emission Techniques for Combustion Diagnostics -High-Resolution Visualization of Turbulent Reacting Flows

    Författare :Bo Li; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PLIF; LIF; Laser-Induced Fluorescence; Rayleigh scattering; Laser Diagnostics; flame font; Combustion; Turbulence; Photofragmentation LIF; PF-LIF; Laser-induced Phosphorescence; LIP; Fysicumarkivet A:2012:Li;

    Sammanfattning : Nowadays, more than 90% of our energy comes from combustion processes. Hence, it is very important to perform combustion research to reduce emissions, improve efficiency, find clean and renewable fuels, strengthen safety, etc. LÄS MER

  4. 4. Time-resolved laser spectroscopic studies of atoms, ions and Molecules

    Författare :Zhongshan Li; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:2000:Li;

    Sammanfattning : Time-resolved laser spectroscopy has been performed to study the radiative properties of various microscopic systems. Using Laser-Induced Fluorescence (LIF) techniques, natural radiative lifetimes have been studied not only in neutral B, S, Ge, Ce, Pb, and in singly ionized V, Fe, Zr, Mo, La, Ce, Eu, Gd and Yb, but also in doubly ionized La, Ce, Pr, Eu, Er, Gd, Tm, Lu, and W.

  5. 5. Numerical simulations of flow discharge and behaviours in spillways

    Författare :Shicheng Li; Anders Ansell; James Yang; Sébastien Erpicum; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Spillway; step geometry; discharge prediction; flow behaviour; machine learning; computational fluid dynamics; Utskov; steggeometri; avbördningsuppskattning; flödesbeteende strömningsegenskap; maskininlärning; flödesdynamisk beräkningsanalys numerisk simulering; Betongbyggnad; Concrete Structures;

    Sammanfattning : A spillway is an important component of a dam and serves as a flood release structure. It achieves controlled discharge of water and protects the dam from overtopping. The majority of the hydropower dams were built before the 1980s, and many spillways are undersized in light of the present design flood guidelines. LÄS MER
