Digital Cement Integrity: A Methodology for 3D Visualization of Cracks and Microannuli in Well Cement
(Peer reviewed; Journal article, 2020)Leakages of greenhouse gases, such as methane and carbon dioxide from wells, may have considerable environmental consequences. Although much emphasis is currently put on understanding well barrier failures, and thus, ... -
Digital Image Correlation Technique to Aid Monotonic and Cyclic Testing in a Noisy Environment during In Situ Electrochemical Hydrogen Charging
(Peer reviewed; Journal article, 2022)Hydrogen is receiving growing interest as an energy carrier to facilitate the shift to a green economy. However, hydrogen may cause the significant degradation of mechanical properties of structural materials, premature ... -
Digitalization of Battery Manufacturing: Current Status, Challenges, and Opportunities
(Peer reviewed; Journal article, 2021)As the world races to respond to the diverse and expanding demands for electrochemical energy storage solutions, lithium-ion batteries (LIBs) remain the most advanced technology in the battery ecosystem. Even as unprecedented ... -
Dipentamethylene thiuram tetrasulfide-based cathodes for rechargeable magnesium batteries
(Peer reviewed; Journal article, 2020)Rechargeable Mg batteries (RMBs) represent a possible route for low-cost energy storage applications, but they are lacking a satisfactory cathode material. Conventional sulfur (S8) cathodes have shown promise, yet they ... -
Direct air capture (DAC) deployment: National context cannot be neglected. A case study applied to Norway
(Peer reviewed; Journal article, 2023)DAC deployment is still an open question. Recent publications focused on energy consumption and the relationship between the cost of captured CO2 and operating conditions. These works addressed a preliminary assessment of ... -
Direct dimethyl ether synthesis from synthesis gas: The influence of methanol dehydration on methanol synthesis reaction
(Peer reviewed; Journal article, 2016)Direct dimethyl ether (DME) synthesis from synthesis gas is studied with regard to potential effects of methanol dehydration on methanol formation and copper-based catalyst performance. For this, the influence of the ... -
Direct Method for Producing Scandium Metal and Scandium-Aluminium Intermetallic Compounds from the Oxides
(Journal article; Peer reviewed, 2018)The electrochemical de-oxidation process, also called FFC-Cambridge process, has been proposed previously to produce reactive metals and their alloys through reduction of their metal oxides. The process works by introducing ... -
Direct Observation of Charge Transfer between NOx and Monolayer MoS2 by Operando Scanning Photoelectron Microscopy
(Peer reviewed; Journal article, 2021)Atomically thin transition-metal dichalcogenides (MoS2, WSe2, etc.) have long been touted as promising materials for gas detection because of their tunable band gaps; however, the sensing mechanism, based on a charge-transfer ... -
Disagreements between space charge models and grain boundary impedance data in yttrium-substituted barium zirconate
(Peer reviewed; Journal article, 2020)Although the space charge model is commonly used to explain the high grain boundary resistance in proton conducting yttrium-substituted BaZrO3, it fails in its simplest forms with factors 10–40 to fit experimental data ... -
Discarded gems: Thermoelectric performance of materials with band gap emerging at the hybrid-functional level
(Peer reviewed; Journal article, 2021)A finite electronic band gap is a standard filter in high-throughput screening of materials using density functional theory (DFT). However, because of the systematic underestimation of band gaps in standard DFT approximations, ... -
