Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The Innovations and Industrial Internet project was formed with partners from Luleå University of Technology, Sweden, Centria University of Applied Sciences, Finland, and University of Tromsø, campus Narvik, Norway. The work has addressed an increase in small and medium sized enterprises’ competences of applying modern digital technology to benefit product- and service development in the region. Almost 40 companies have been keenly involved in the project’s activities, which have included, for example, case studies, demonstrations, workshops and seminars. The close academia and company collaborations has resulted in SMEs’ test and evaluation of new technologies, in turn leading to the implementation of new methods that were new to 16 of those companies.The project collaborations have resulted in 9 products and services that were new to the companies. A number of cross-border collaborations among companies and universities across the program region have been finalized, for example a case on 3D printing and boat production which involved all partners competences. The cross-border added value does not only encompass the open accessible milieu bringing all partners expertise together to benefit SMEs in the region, but it also identified and mitigated barriers between knowledge domains, like the ones occurring in value chain collaborations where digital solutions often dissolve some aspects of a problem while simultaneously cause new ones.The project has had a fairly good representation of females in leading positions since the project leader and one country’s leader are females, but also the female representation in activities has been good.The project has been nominated to the Regio Stars Award 2017.

Integrating Cobalt-sites-rich Aza-fused Conjugated Microporous Polymers on BiVO4 for Efficient Photoelectrochemical Water Splitting
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Advanced surface and interface engineering has been demonstrated to be of critical importance for the development of photoanodes for highly efficient photoelectrochemical (PEC) water oxidation. In this study, cobalt-sites-rich aza-fused conjugated microporous polymer was integrated on the nanoporous bismuth vanadate electrode. The hybrid BiVO4/eCMP-Co photoanode exhibited a high photocurrent density of 4.3 mA cm-2 at 1.23 VRHE and a very low onset potential of ~ 0.2 VRHE with an applied bias photon to current efficiency of 1.62% at around 0.6 VRHE. Moreover, studies on charge carrier kinetics showed that eCMP-Co can not only accelerate water oxidation kinetics but also significantly suppress surface recombination, thereby dramatically increasing charge transfer efficiency. These results demonstrate the great potential of conjugated polymers combined with metal coordination as heterogenous catalysts on photoelectrodes in PEC devices.

Ultra-thin Nanolayers of Photodeposited Cobalt Phytate on BiVO4 for Efficient Photoelectrochemical Water Oxidation
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Strategical engineering of semiconducting films by loading co-catalysts is pivotal for optimizing the properties of photoelectrodes used for solar fuel production. In this study, an ultrathin layer of cobalt phytate (CoPhy) was integrated onto the nanoporous bismuth vanadate (BiVO4) photoanode by a simple photo-assisted electrodeposition method. The introduction of CoPhy significantly improved the PEC performance of BiVO4 photoanode, displaying a photocurrent density up to 4.3 mA cm-2 at 1.23 V (vs. reversible hydrogen electrode (RHE), AM 1.5G) and an impressive early onset of potential of ~0.2 VRHE as well as superior stability. Moreover, charge kinetics studies showed that the enhancement in PEC performance by CoPhy is primarily due to the suppression of surface recombination and acceleration of interfacial charge transfer.

Structure of SOQ1 lumenal domains identifies potential disulfide exchange for negative regulation of photoprotection, qH
- 2024

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Non-photochemical quenching (NPQ) plays an important role for phototrophs in decreasing photo-oxidative damage. qH is a sustained component of NPQ and depends on the plastid lipocalin (LCNP). A thylakoid membrane-anchored protein SUPPRESSOR OF QUENCHING1 (SOQ1) prevents qH formation by inhibiting LCNP. SOQ1 suppresses qH with its lumen-located C-terminal Trx-like and NHL domains. Here we report crystal structures and biochemical characterization of SOQ1 lumenal domains. Our results show that the Trx-like and NHL domains are stably associated, with the potential redox-active motif located at their interface. Residue E859 essential for SOQ1 function is pivotal for mediating the inter-domain interaction. Moreover, the C-terminal region of SOQ1 forms an independent β-stranded domain, which possibly interacts with the Trx-like domain through disulfide exchange. Furthermore, SOQ1 is susceptible to cleavage at the loops connecting the neighboring domains both in vitro and in vivo, which could be a regulatory process for its suppression function of qH.
