Nano fabricated silicon nanorod array with titanium nitride coating for on-chip supercapacitors
(Journal article; Peer reviewed, 2016)We demonstrate high aspect ratio silicon nanorod arrays by cyclic deep reactive ion etching (DRIE) process as a scaffold to enhance the energy density of a Si-based supercapacitor. By unique atomic layer deposition (ALD) ... -
Nano-Power Monostable-Based Wake-Up Mechanism for Wireless Sensor Networks
(Chapter, 2022)Wireless sensor networks (WSNs) generally consist of thousands of sensor nodes, each one supplied by a battery or harvested energy. To prolong the lifetime of wireless sensor networks, wake-up receivers (WuRxs) are typically ... -
Nanoscale hetero-structured Co-Co(OH)2 composite/amorphous carbon core/shell bi-functional electrocatalysts electrochemically evolved from metastable hexagonal-phase cobalt for overall water splitting
(Peer reviewed; Journal article, 2021)Bi-functional electrocatalysts suited to alkaline water splitting systems are highly pursued, towards the most realistic application enabled by simplified electrolyzer design and cost-effective operation. Herein, a novel ... -
Nanoscale imaging of shale fragments with coherent X-ray diffraction
(Peer reviewed; Journal article, 2020)Despite the abundance of shales in the Earth's crust and their industrial and environmental importance, their microscale physical properties are poorly understood, owing to the presence of many structurally related mineral ... -
National Parks in Northern Sweden as Refuges for Illegal Killing of Large Carnivores
(Journal article; Peer reviewed, 2016)Large protected areas are often considered to be as important as population size in reducing extinction risk for large carnivores. However, the effectiveness of protected areas for large carnivore survival has rarely been ... -
Naturally changing reference conditions: Evidence of isostatic uplift being the main cause of changes in ecological status in a SW Norwegian fjord system
(Peer reviewed; Journal article, 2021)According to the European Water Framework Directive (WFD), restoration actions are needed if the present-day ecological quality status (EcoQS) is worse than good. However, less stringent environmental objectives may be ... -
A nature-based solution to a landfill-leachate contamination of a confined aquifer
(Peer reviewed; Journal article, 2021)Remediation of groundwater from landfill contamination presents a serious challenge due to the complex mixture of contaminants discharged from landfills. Here, we show the significance of a nature-based solution to a ... -

Near Well CFD Simulation of SAGD Extra Heavy Oil Production
(Journal article; Peer reviewed, 2015-11-25)Near well computational fluid dynamic simulation for extra heavy oil production using steam assisted gravity drainage was studied with ANSYS Fluent software. Computational fluid dynamic simulation can predict the multiphase ... -
Near Well Simulation and Modelling of Oil Production From Heavy Oil Reservoirs
(Conference object; Peer reviewed, 2015-11-25)Heavy oil reservoirs cover up two third of the world's hydrocarbon reservoirs. Even though it is vast energy resource, heavy oil recovery is not considered economical due to its high viscous properties. Generally horizontal ... -
Near Well Simulation of CO2 Injection for Enhanced Oil Recovery (EOR)
(Journal article; Peer reviewed, 2015-11-25)A major challenge in oil industry is the declining oil production and the relatively low recovery rate. Estimates show that although the oil is localized and mobile, more than half of the oil is remaining in the reservoir ... -
Near Well Simulation of Extra-Heavy Oil Production Using SAGD
(Conference object; Peer reviewed, 2015-11-25)Heavy oil and bitumen represent a massive world resource more than twice the size of global reserves of light or conventional oil. In reservoirs with extra heavy oil and bitumen, thermal methods are used to reduce the oil ... -
Near-well simulation of oil production from a horizontal well with ICD and AICD completions in the Johan Sverdrup field using OLGA/ROCX
(Journal article; Peer reviewed, 2020)One of the main principles of improving oil recovery is maximizing the contact area between the well and the reservoir. To achieve this purpose especially in reservoirs with a thin oil column, long horizontal wells are ... -
Nearwell Simulation of a horizontal well in Atlanta Field in Brazil with AICV® completion using OLGA/Rocx
(Journal article; Peer reviewed, 2015-11-25)Brazil has special attention in the world oil scenario due its recent findings of oil reservoirs. Most of these reservoirs are heavy oil. The increasing energy consumption and discovery of heavy oil reservoirs require more ... -
The Need for Systems Awareness to Support Early-Phase Decision-Making—A Study from the Norwegian Energy Industry
(Peer reviewed; Journal article, 2021)In this paper, we explore the need to improve systems awareness to support early-phase decision-making. This research uses the Norwegian energy industry as context. This industry deals with highly complex engineering systems ... -
NEQ rate based modeling of an absorption column for post combustion CO2 capturing
(Journal article; Peer reviewed, 2011-04-01)Post combustion CO2 capture via absorption into aqueous alkanolamine systems is considered to be the most mature and potential technique for CO2 removal from the power plants' exhaust gases. Modeling and simulation of such ... -
