Formation of Hydroxyapatite via Transformation of Amorphous Calcium Phosphate in the Presence of Alginate Additives
(Journal article; Peer reviewed, 2019)Hydroxyapatite (HA) is the primary mineral of vertebral tooth and bone tissue; thus, it is often incorporated into synthetic composite materials designed for hard tissue engineering applications. Understanding the formation ... -
Fotokatalyse - Fotokatalytisk Hydrogen Produksjon Gjennom Foto-reforming av Hydrokarboner
(Master thesis, 2014)I løpet av det siste vårsemesteret på masterstudium i industriell kjemi, ble det kjørt en rekke eksperimenter i fotokatalyse, for å undersøke optimale driftsforhold ved ett skifte av alkohol til glyserol. Andre alkoholer ... -
Fotokatalystisk hydrogenproduksjon gjennom fotoreforming av hydrokarboner
(Master thesis, 2013)Hensikten med dette prosjektet var å undersøke Cu-TiO2 som fotokatalysator for fotoreforming av metanol. Dette er en prosess der hydrogen blir produsert fra metanol i vannløsning ved hjelp av UV-lys og en fotokatalysator. ... -
Fotokatalytisk drivstoff-produksjon gjennom fotoreforming av hydrokarboner
(Master thesis, 2011)The purpose of this study is to investigate the photoreforming of methanol for hydrogen production. Since the photocatalysis field needs a cheaper efficient photocatalyst than the more common Pt loaded TiO2, CuO loaded ... -
Fractionation of Transition Metals by Solvent Extraction and Precipitation from Tannic Acid-Acetic Acid Leachate as a Product of Lithium-Ion Battery Leaching
(Peer reviewed; Journal article, 2022)Solvent extraction and precipitation schemes are applied to isolate copper, cobalt, manganese and nickel from leachate, produced from spent lithium-ion battery leaching using tannic acid-acetic acid as lixiviant. The metal ... -
Framework for Combined Diagnostics, Prognostics and Optimal Operation of a Subsea Gas Compression System
(Journal article, 2017)The efficient and safe operation of subsea gas and oil production systems sets strict requirements to equipment reliability to avoid unplanned breakdowns and costly maintenance interventions. Because of this, condition ... -
A framework for predicting odor threshold values of perfumes by scientific machine learning and transfer learning
(Journal article; Peer reviewed, 2023)Knowledge of odor thresholds is very important for the perfume industry. Due to the difficulty associated with measuring odor thresholds, empirical models capable of estimating these values can be an invaluable contribution ... -
From hybrid solvents to water-lean solvents – A critical and historical review
(Journal article; Peer reviewed, 2020)Every year, a plethora of studies focused on developing water-lean solvents for CO2 capture is published in the scientific literature. More often than not, these studies lack a satisfactory contextualization with the ... -
From Nickel Ore to Ni Nanoparin the Extraction Process: Properties and Application
(Journal article; Peer reviewed, 2023)Laterite nickel ore is a mineral rock, which contains iron–nickel oxide compounds. One processing technology proposed to treat the ore is the Caron process. In general, the Caron process combines pyrometallurgical and ... -
