Interlinked and integrated research support services
Authors: Ikonen Arto 
Published: November 2022

This poster introduces the efficient set of research support services available in University of Jyväskylä’s (JYU) Open Science Centre (OSC). The set includes several essential services for researchers to help them execute an open and responsible research process.
The continuous improvement of research support services has led to an interlinked, integrated and harmonious set of technical solutions, processes and workflows which meet the needs of researchers and help them implement open science and FAIR policies in practice. They also save time and enable better working processes for the researchers but also for the experts conducting these services.
The poster describes two main services which are interlinked and which both aim to make processes and workflows effortless.
One of the main services is when metadata from research information system Converis is utilized using API in the self-archiving process of research articles to the institutional repository. OSC’s experts record the publication metadata on behalf of researchers and the same metadata of the publications is used in the self-archiving process.
Also, data harvesting is used to get notification of new publications of researchers affiliated to JYU. Often the researchers don’t even have to inform OSC when their new publication is out. This effortless process combines two different systems (CRIS and institutional repository) and connects workflows regarding them.
The poster also introduces a dynamic research data management tool which enables a fluent data management process. The goal of the development of this tool has been to free the researchers of having to learn the use of several different systems. The tool helps the researchers to track the handling process of their data and guides through all the necessary phases of the data management process. Again, the data once recorded is being utilized in other systems and in other phases of the whole process. Both the tool and the data management process it enables are integrated to other systems which are needed for example in storing and sharing the research data.

Aims: To refix the critical limit of Cu in the soils of the major rice-growing tracts of Tamil Nadu.
Study Design: Completely Randomized Design and Randomized Block Design.
Place and Duration of Study: Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University between 2015 to 2018.
Methodology: The pot culture study was conducted in the laboratory followed by the field trials in the selected farmers'plot itself. The soil and plant samples are analyzed for soil copper and the data were statistically analyzed by following the standard procedures.
Results: The Cu deficient soils showed a significant response to the application of graded levels of Cu. For obtaining higher rice production in severely Cu-deficient soils (L1 to L9: 0.33 to 0.95 mg kg-1), the Cu fertilizers may be applied @ 1.50 kg ha-1 i.e. 6.0 kg CuSO4 ha-1 (+ NPK) while in moderately Cu deficient soils (L10 to L13: 1.28 mg kg-1), the Cu level @ 1.00 kg ha-1 i.e. 4.0 kg CuSO4 ha-1 (+ NPK) increased significantly the grain and straw yields and in soils having high initial Cu status (L14, L15: 1.91, 2.12 mg kg-1), the Cu level @ 0.50 kg ha-1 i.e. 2.0 kg CuSO4 ha-1 (+ NPK) showed a significant increase in grain and straw yields.
Conclusion: The present investigation was carried out with the objective of re-fixing the critical limit in wetland soils and accordingly the critical limit for DTPA - Cu in wetland soils and rice crops at the panicle initiation stage was re-fixed as 0.93 and 4.82 mg kg-1, respectively. Based on this, it is possible that a graded dose of micronutrient fertilizers (Cu) may be prescribed to rice crops for the major rice-growing soils.

Background: The objective of this study was to analyse the clinical characteristics of HIV+ and HIV- tuberculosis patients followed and treated at the Oyem Regional Hospital Centre (ORHC).
Materials and Methods: During this study conducted between January 2019 and December 2021, data collection was based on the exploitation of medical records and registers of results from the medical analysis laboratory of the regional hospital of Oyem, in which there were personal data (gender and age) of the patients, the status of HIV infection, clinical characteristics (pulmonary or extra pulmonary TB), and finally, the therapeutic outcomes of the patients after anti-tuberculosis and antiretroviral treatment. Binomial test following the Normal distribution was used to find an association between the percentages of extrapulmonary TB and TB+/HIV+ co-infection.
Results: In this study, 128 confirmed TB cases were selected. While 54 (42.19%) were co-infected with TB+/HIV+, 74 patients (57.81%) were monoinfected with TB+/HIV+. Among all these patients, 93 (72.66%) were reported to have extra pulmonary TB and 35 (27.34%) had pulmonary TB. A normal binomial test showed that TB+/HIV+ co-infection was significantly associated with extrapulmonary TB (p=0.04). Patients were put on anti-tuberculosis treatment according to the manufacturers' indications. Despite a total of 15 deaths (8.93%) in both mono- and co-infected patients, there was a favourable outcome, with 35 patients (27.34%) declared cured. With 8 deaths, mortality was higher in the co-infected than in the non-HIV infected TB patients who recorded 7 deaths.
Conclusion: By indicating a relatively high prevalence of HIV infection in TB patients, this study showed that TB+/HIV+ co-infection was associated with extra pulmonary TB, the severe form of the disease, and increased mortality in patients, hence the need to strengthen joint activities to control this co-infection.
Nonlinear filtering‐based output tracking error constraint control for permanent magnet synchronous motors with complete unknown coefficients
Authors: Wang Jinying , Wang Yanping 
Published: November 2022

SummaryThis article investigates the problem of the output tracking error constraint performance for permanent magnet synchronous motors with complete unknown coefficients. First, to achieve the output tracking error constraint performance, an improved barrier Lyapunov function combined with exponent‐type performance is given. Then, to erase the effects of unknown coefficients, adaptive compensation strategy, fuzzy logic systems, and Nussbaum‐type function are utilized, which relax the assumption requirement that the partial coefficients must be known in the related results. Further, to simplify the control design, a novel nonlinear filters‐based dynamic surface control method is presented. Unlike the previous linear filters‐based ones, it can achieve better control performance. It is proved that by utilizing the proposed method, all the signals in the closed‐loop systems are bounded, and also the prescribed output tracking error constraint condition does not violate. Final, simulation example verify the effectiveness of our proposed method.

AbstractThe success of using 2D Ruddlesden‐Popper metal halide perovskites (MHPs) in optoelectronic devices has ignited great interest as means for energy level tuning at the interface with 3D MHPs. Inter alia, the application of 2D phenylethylammonium lead quaternary iodide (PEA2PbI4)/3D MHPs interfaces has improved various optoelectronic devices, where a staggered type‐II energy level alignment is often assumed. However, a type‐II heterojunction seems to contradict the enhanced photoluminescence observed for 2D PEA2PbI4/3D MHP interfaces, which raises fundamental questions about the electronic properties of such junctions. In this study, using direct and inverse photoelectron spectroscopy, it is revealed that a straddling type‐I energy level alignment is present at 2D PEA2PbI4/3D methylammonium lead triiodide (MAPbI3) interfaces, thus explaining that the photoluminescence enhancement of the 3D perovskite is induced by energy transfer from the 2D perovskite. These results provide a reliable fundamental understanding of the electronic properties at the investigated 2D/3D MHP interfaces and suggest careful (re)consideration of the electronic properties of other 2D/3D MHP heterostructures.

AbstractQuasi‐2D Ruddlesden‐Popper perovskites receive tremendous attention for application in light‐emitting diodes (LEDs). However, the role of organic ammonium spacers on perovskite film has not been fully‐understood. Herein, a spacer cation assisted perovskite nucleation and growth strategy, where guanidinium (GA+) spacer is introduced into the perovskite precursor and at the interface between the hole transport layer (HTL) and the perovskite, to achieve dense and uniform perovskite films with enhanced optical and electrical performance is developed. A thin GABr interface pre‐formed on HTL provides more nucleation sites for perovskite crystal; while the added GA+ in perovskite reduces the crystallization rate due to strong hydrogen bonding interacts with intermediates, which promotes the growth of enhanced‐quality quasi‐2D perovskite films. The ionized ammonium group (NH3+) of GA+ also favors formation of polydisperse domain distribution, and amine or imine (NH2 or NH) group interact with perovskite defects through coordination bonding. The spacer cation assisted nucleation and growth strategy is advantageous for producing efficient and high‐luminance perovskite LEDs, with a peak external quantum efficiency of over 20% and a luminance up to 100 000 cd m−2. This work can inform and underpin future development of high‐performance perovskite LEDs with concurrent high efficiency and brightness.

Published: November 2022

AbstractEffective therapy of infection impaired tissue defects has long been an important but challenging topic, and alternative antibiotic‐free solutions are greatly demanded to tackle bacterial infections and promote tissue repair. Herein, the use of supercharged gold nanoclusters (AuNCs) with enhanced enzyme mimic activity as novel interface modulator of bioactive glass nanoparticles (BGN) for infected wound treatment is reported. The supercharged AuNCs exhibit extraordinary affinity toward BGN, leading to the robust immobilization of AuNCs on BGN (BGN‐AuNCs). Functional AuNCs endow BGN with superior peroxidase‐like activity for catalytic antibacterial action, which can kill bacteria with a concentration down to 75 µg mL−1 within 6 h due to the production of highly toxic ·OH. Moreover, expression level of COL‐1, TGF‐β, and FGF‐2 in fibroblasts is actively up‐regulated to 2.9, 3.1, and 1.6 times higher than that of control group due to the positive effect of BGN‐AuNCs on cell proliferation. Meanwhile, intrinsic photoluminescent property of AuNCs enables the direct visualization of BGN at both in vitro and in vivo levels for potentially bioimaging‐guided therapy. Further in vivo results demonstrate that BGN‐AuNCs hold enormous promise for infectious disease therapy and pro‐regeneration, and the proposed supercharged interface engineering strategy is attractive for developing advanced functional nanomedicines.

Published: November 2022

AbstractTumor‐specific combination therapy has shown great promise in cancer theranostics. However, the therapeutic efficacy is usually suppressed because most of the therapeutic systems are not able to synchronously activate their different therapeutic approaches and the local concentration of tumor‐associated stimulus is generally insufficient to fully activate the combination therapy process. Herein, a MnO2‐doped CeO2 nanozyme‐based nanomedicine (Ce6@CMNRs) is reported for tumor‐specific synchronously activated chemodynamic/photodynamic combination therapy. The tumor‐overexpressed H2O2 substitutes the Ce6 on Ce6@CMNRs surfaces via competitive coordination and then decomposes into •OH under acidic condition, achieving the chemodynamic therapy (CDT). Meanwhile, the substituted Ce6 triggers photodynamic therapy (PDT) under laser irradiation that is suppressed before the substitution occurs. Thus, H2O2 can synchronously activate both CDT and PDT of Ce6@CMNRs with a similar level in tumor sites. Moreover, the activated PDT‐induced oxygen starvation further triggers the generation of H2O2 to continuously replace the residual Ce6 coordinated on the nanorod surface, thereby leading to the full activation of PDT and CDT. Also, the doped MnO2 enhances the generation of •OH and provides high contrast for magnetic resonance imaging (MRI) with the help of glutathione. Therefore, Ce6@CMNRs are promising candidates for MRI‐guided CDT/PDT combination therapy with minimized side effects and high efficiency.

AbstractThe present work is designed to discover new perovskite‐based materials, which are expected to show high mechanical stability during their applications, using machine learning (ML) techniques, and based on the Pugh's criterion for distinguishing brittle and ductile behaviors. For this purpose, ML models to predict the moduli of materials, bulk (B) and shear (G), are built using their crystal structure and composition information. The ML process is initiated with the information of 5663 compounds, including composition, crystal structure and moduli, as listed in AFLOW database. Following a procedure of data characteristics, feature generation, feature processing, training, and testing, the ML models are constructed with acceptable accuracy (tenfold cross‐validation R2score of 0.90 and 0.89 for B and G, respectively). The validation process of the models, which is conducted using the corresponding density functional theory calculations, reveals that these models are reliable to be employed in a large‐scale screening process. Indeed, the B‐ and G‐based ML models are incorporated in a screening process, and this is also conjugated with other screening criterions, to find out thermodynamically stable and formable perovskite‐based materials with improved mechanical performance.

AbstractTrigonal planar units with large polarizability anisotropy and high physicochemical stability are ideal structural units for exploring nonlinear optical (NLO) materials. Integrating the merits of two types of triangular‐like moieties, a family of second‐order NLO‐active hybrid halides, MATX (X = Cl (1), Br (2), and I (3)), are achieved. MATX crystallizes in a nonpolar space group of 2c but exhibits the optimal spatial arrangement and superior NLO performance. The low coordination planar trigonal AgX3 units enable segregation in layers of the three‐winged propeller‐like Me3TPA units. All of the layers are packed in a perfect parallel fashion, making the functional materials exhibit superior NLO performances, including the phase matchable behavior with strong SHG responses (6.2/1, 6.5/2, and 7.6/3 times that of potassium dihydrogen phosphate), large birefringence (0.232/1, 0.252/2 and 0.260/3 at 1064 nm), high laser damage threshold, wide transparent window, and easiness of crystal growth. The first‐principles calculations reveal that the coexistence of strong linear and nonlinear optical properties are ascribed to the synergistic effect of the trigonal moieties. This study points out a useful path for the rational design of excellent NLO materials.

AbstractCancer heterogeneity plays a vital part in cancer resistance and metastasis. To provide a reliable approach to exert a therapy action and evaluate its efficiency in heterogeneous cancer cells, a multiple targeting delivery vector composed of histone encapsulating the therapeutic or diagnostic agent, hyaluronic acid targeting CD44 overexpressed in stem tumor cells, SYL3C aptamer targeting epithelial cell adhesion molecule (EpCAM) overexpressed in epithelial cancer cells, and CL4 aptamer targeting epidermal growth factor receptor (EGFR) overexpressed in mesenchymal cancer cells, is developed. The vector can efficiently target different cancer cells and circulating tumor cells (CTCs) in the peripheral blood of patients for mucin 1 (MUC1) knockout. Furthermore, the multiple targeting vector can be used to co‐encapsulate three types of molecular beacons for probing various mRNA biomarkers at single‐cell resolution after genome editing. This study provides an efficient approach for exerting therapeutic actions in heterogeneous cancer cells and assessing the therapeutic efficacy by detection of cancer biomarkers via liquid biopsy.

AbstractThe ability to perform nanometer‐scale optical imaging and spectroscopy is key to deciphering the low‐energy effects in quantum materials, as well as vibrational fingerprints in planetary and extraterrestrial particles, catalytic substances, and aqueous biological samples. These tasks can be accomplished by the scattering‐type scanning near‐field optical microscopy (s‐SNOM) technique that has recently spread to many research fields and enabled notable discoveries. Herein, it is shown that the s‐SNOM, together with scanning probe research in general, can benefit in many ways from artificial‐intelligence (AI) and machine‐learning (ML) algorithms. Augmented with AI‐ and ML‐enhanced data acquisition and analysis, scanning probe optical nanoscopy is poised to become more efficient, accurate, and intelligent.
