Pot-economy autooxidative condensation of 2-Aryl-2-lithio-1,3-dithianes
(2018-02-16)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
The autoxidative condensation of 2-aryl-2-lithio-1,3-dithianes is here reported. Treatment of 2-aryl-1,3-dithianes with n-BuLi in the absence of any electrophile leads to condensation of three molecules of 1,3-dithianes ...
Resonant Absorption in GaAs-Based Nanowires by Means of Photo-Acoustic Spectroscopy
(2018-03-01)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
Semiconductor nanowires made of high refractive index materials can couple the incoming light to specific waveguide modes that offer resonant absorption enhancement under the bandgap wavelength, essential for light harvesting, ...
Directions in QPPR development to complement the predictive models used in risk assessment of nanomaterials
(2018-07-01)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
There is an increasing need for predictive risk assessment of nanomaterials (NMs) using methods that are rapid, accurate and resource efficient. To fulfill this need, the development and use of Quantitative Property Property ...
Program integration in multi-project change programs : agency in integration practice
(2018-05-01)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
Multi-project change programs pursue challenging goals and may suffer from uncertainty and conflicting interests. To achieve their goals, such programs need integration both with the parent organization and between projects. ...
Thermophilic versus mesophilic dark fermentation in xylose-fed fluidised bed reactors : Biohydrogen production and active microbial community
(2018)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
Dark fermentative biohydrogen production in a thermophilic, xylose-fed (50 mM) fluidised bed reactor (FBR) was evaluated in the temperature range 55-70 °C with 5-degree increments and compared with a mesophilic FBR operated ...
Damped Posterior Linearization Filter
(2018)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
In this letter, we propose an iterative Kalman type algorithm based on posterior linearization. The proposed algorithm uses a nested loop structure to optimize the mean of the estimate in the inner loop and update the ...
Standoff alpha radiation detection for hot cell imaging and crime scene investigation
(2018)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
This paper presents the remote detection of alpha contamination in a nuclear facility. Alpha-active material in a shielded nuclear radiation containment chamber has been localized by optical means. Furthermore, sources of ...
GaSb superluminescent diodes with broadband emission at 2.55 μ m
(2018-01)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
We report the development of superluminescent diodes (SLDs) emitting mW-level output power in a broad spectrum centered at a wavelength of 2.55 μm. The emitting structure consists of two compressively strained GaInAsSb/G ...
Composition and role of the attached and planktonic microbial communities in mesophilic and thermophilic xylose-fed microbial fuel cells
(2018)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
A mesophilic (37 °C) and a thermophilic (55 °C) two-chamber microbial fuel cell (MFC) were studied and compared for their power production from xylose and the microbial communities involved. The anode-Attached, membrane-Attached, ...
Formal resource and capability models supporting re-use of manufacturing resources
(2018-02)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
In the field of manufacturing the responsiveness has become a new strategic goal for the enterprises alongside with quality and costs. Efficient responsiveness requires production reconfiguration ranging from layout to ...
