Improving methods in X-ray nanotomography of fibre bonds
X-ray nanotomography has proven to be a useful yet challenging method in the study of cellulose fibre bonds. The challenges encountered in previous researches are related to lengthy imaging times and low success rate per sample. To counter these obstacles, fibre staining in order to enhance contrast in radiographic images and an alternative method for marker particle placement were examined in this study. Cesium iodide proved to be a suitable staining material, and the alternative method for particle placement may increase success rate by reducing microfibril structure fracturing during the marker placement process.

Measuring the contact area in cellulose fibre bonds using X-ray nanotomography
Sormunen, Tuomas (2018)Paperi on stokastinen verkosto toisiinsa eri vuorovaikutusten, tärkeimpänä vetysidosten, avulla sitoutuneita sellukuituja. Paperin lujuus riippuu yksittäisten kuitusidosten lujuudesta ja sidospinta-alasta. Todellista ... -
Improved Reactivity and Derivatization of Cellulose after Pre-Hydrolysis with Commercial Enzymes
Willberg-Keyriläinen, Pia; Ropponen, Jarmo; Lahtinen, Manu; Pere, Jaakko (North Carolina State University, 2019)Reactivity is an important parameter when considering the chemical modification or dissolution of cellulose. Different pretreatment methods affect cellulose reactivity by decreasing its degree of polymerization (DP) and ... -
Teachers and upper secondary school students' views on the role of teacher feedback in motivating Finnish EFL students to improve their written skills
Vornanen, Katariina (2021)Opettajapalaute on merkittävä osa niin opettajien työtä kuin oppilaiden oppimisprosessia. Samalla tavalla myös oppilaiden motivaatio voi olla merkittävä tekijä oppimisen edistymisessä. Tässä tutkimuksessa kartoitetaan ... -
A post-exercise infrared sauna session improves recovery of neuromuscular performance and muscle soreness after resistance exercise training
Ahokas, Essi K.; Ihalainen, Johanna; Hanstock, Helen G.; Savolainen, Eero; Kyröläinen, Heikki (Termedia Sp. z.o.o., 2023)The aim of this study was to investigate effects of a single infrared sauna (IRS) session on postexercise recovery of neuromuscular performance, autonomic nervous system function, subjective sleep quality, and muscle ... -
Improved Radio-Cesium Detection Using Quantitative Real-Time Autoradiography
Ang, Joyce W. L.; Bongrand, Arthur; Duval, Samuel; Donnard, Jérôme; Parkkonen, Joni; Utsunomiya, Satoshi; Koivula, Risto; Siitari-Kauppi, Marja; Law, Gareth T. W. (American Chemical Society (ACS), 2023)Cesium-134 and -137 are prevalent, long-lived, radio-toxic contaminants released into the environment during nuclear accidents. Large quantities of insoluble, respirable Cs-bearing microparticles (CsMPs) were released into ...
