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, ...
Urbanisoituva yliopistokampus informaalin oppimisen mahdollistajana
(2018)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
Yliopistokampukset ovat monitoimijaisia ja alati muuttuvia opiskelu-, työ-, asuin- ja harrastusympäristöjä. Niiden muutosprosessi on sidoksissa yliopistojen yhteiskunnallisiin kytkentöihin sekä kaupungin laajenemiseen, ...
A portable live-cell imaging system with an invert-upright-convertible architecture and a mini-bioreactor for long-term simultaneous cell imaging, chemical sensing and electrophysiological recording
(2018)
- /dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
<p>Cell culture in-vitro is a well-known method to develop cell and disease models for studying physiologically relevant mechanisms and responses for various applications in life sciences. Conventional methods for instance, ...
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 ...
