Determination of Resistance of Winter Wheat Varieties Against Root and Crown Rot Fusarium culmorum Under the Artificial Drought Conditions
Authors: Özdemir Fatih
Published: October 2023

This study was conducted to investigate the relationship between the recent increase in the frequency of drought conditions and Root-Crown Rot (Fusarium pseudograminearum, Fusarium culmorum) in rainfed wheat growing areas of Central Anatolia. In 2018, the experiment was established in the greenhouse of Konya Bahri Dağdaş International Agricultural Research Institute using 25 registered wheat varieties in a randomised block split-plot experimental design with 4 replications. Irrigation levels (100% field capacity and 50% field capacity) were designed as main plots, inoculation (+ and -) as subplots and varieties as sub-subplots. In the study, the response of the cultivars to inoculation under artificial drought conditions was evaluated by measuring Crown Score (CR), Lesion Length (LL), Number of Diseased Leaves from outside to inside (NDL) and Plant Height (PH) from five plants in each pot. Statistically, the differences between inoculation, irrigation, NDL and LL were found to be significant at P<0.0001 level, while the differences between varieties were found to be significant at P<0.001 level for the CR parameter. On the other hand, when the interactions were evaluated for the NDL parameter, the differences were found to be significant at P<0.0001 level for all three interactions of cultivar*inoculation, cultivar*irrigation and cultivar*inoculation*irrigation. When the effect of reduced water application intended to be used in resistance breeding was evaluated for 25 different varieties under Fusarium culmorum inoculation, there was an increase in CR from 41,7% (Gerek-79) to 487,5% (Altay-2000), NDL from 7,14% (Kirgiz-95) to 200% (Alpu-2001), LL from -36,84% (Karahan-99) to 283,33% (Altay-2000) and in PH reduction from 12,41% (Seval) to 32,22% (Kirgiz-95). The results showed that drought-stressed plants were already weakened and therefore more easily and severely infected by pathogens. According to these results, it has been determined that it is very important for the region to obtain resistance to drought and crown rot diseases, which have such an obvious relationship, in breeding studies.

Published: October 2023

The preparations of organometallic molecules have provided new philosophy in molecular science. The synthesis of these molecules featured in easy construction, modification and broad chemical space coverage comparing to the access of carbon centered compounds. The stereochemistry of these molecules have long been the great challenge due to the large atom radius therefore more outer sphere electrons give rise to more valency. Transition metals centered molecules in particular become the new summit for the studies of these molecules with respect to the design, synthesis and analysis. We herein report the construction and resolution of a number of ruthenium piano-stool shaped complexes, and stability studies of these complexes. Furthermore, 5 conformational isomers were detected in complex 16, the rotate barrier between the two conformations was around 3 kcal/mol. These results have provided new evidences for the design of molecules with specific fine stereochemical information for potential applications in medicinal and material chemistry.
High molecular weight crystalline PEO6 based polymer electrolytes for lithium-ion conduction– Effect of cellulose nano whiskers
Authors: C.V. Ram Shankar , Deo Shyam , Zhan Pengfei , Janik Michael , K. Maranas Janna
Published: October 2023

We explore the crystal structure and ionic conductivity of unfilled and cellulose nanowhisker-filled polymer electrolytes, based on high molecular weight PEO and LiClO4 at a concentration EO: Li = 6:1 (EO=ether oxygen). At this concentration, the polymer electrolyte forms crystalline PEO6 [PEOy - the crystal structure co-crystallizes ‘y’ PEO ether oxygens to one Li-anion pair]. While the diffraction patterns for PEO3 and PEO6 with LiClO4 are available, their structures are not. Thus, we optimize these structures using density functional theory and show agreement between simulated and experimental diffraction patterns. The PEO6 crystal shows insufficient Li-ion conductivity due to a lack of percolated conduction paths, and the crystal structure is unstable following two months after annealing. Cellulose nanowhiskers, with their patterned surface -OH groups, extend the length of PEO6 tunnels, stabilize these tunnels for as long as a year, and result in the percolation of crystals. Although the EO: Li = 6:1 stoichiometry should not favor PEO3 formation, we observe this crystal phase in some unfilled samples. But, with the addition of nanowhiskers, the patterned surface templates PEO6 formation rather than PEO3. Despite these advantages, nanowhiskers do not improve ionic conductivity as hypothesized. The tools developed in this work allow further mechanistic exploration of conduction through crystalline domains.
EPD-iSCAT: Electrophoretic Mass Photometry
Authors: Kowal Matthew , Seifried Teresa , Brouwer Carraugh , Tavakolizadeh Hooman , Grant Edward
Published: October 2023

Interferometric scattering microscopy (iSCAT) has rapidly developed as a quantitative tool for the label-free detection of single macromolecules and nanoparticles. In practice, this measurement records the interferometric scattering signal of individual nanoparticles in solution as they land and stick on a coverslip, exhibiting an intensity that varies linearly with particle volume, and an adsorption rate that reflects the solution-phase transport kinetics of the system. Together, such measurements provide a multidimensional gauge of particle size and concentration in solution over time. However, the landing kinetics of particles in solution also manifest a measurement frequency limitation imposed by the slow long-range mobility of particle diffusion to the measurement interface. Here we introduce a new technique that offers a novel means to overcome the inherent diffusion-controlled sampling limitation of spontaneous mass photometry. We term this methodology, electrophoretic deposition interferometric scattering microscopy (EPD-iSCAT). This approach uses a coverslip supporting a conductive thin film of indium tin oxide (ITO). Charging this ITO film to a potential of around 1 V electrophoretically draws charged nanoparticles from solution and binds them in the focal plane of the microscope. Regulating this potential offers a direct means to control particle deposition. Thus, we find for a 0.1 nM solution of 50 nm polystyrene nanoparticles that the application of +1 V to an EPD-iSCAT coverslip assembly drives a electrophoetic deposition rate constant of 1.7 s−1 μm−2 nM−1. Removal of the potential causes deposition to cease. This user control of EPD-iSCAT affords a means to apply single-molecule mass photometery to monitor long-term changes in solution owing to slow kinetic processes. In contrast with conventional coverslips chemically derivatized with charged thin films, EPD-iSCAT maintains a deposition rate that varies linearly with bulk concentration.

Published: October 2023

Data science is assuming a pivotal role in guiding reaction optimization and streamlining experimental workloads in the evolving landscape of synthetic chemistry. A discipline-wide goal is the development of workflows that integrate computational chemistry and data science tools with high-throughput experimentation as it provides experimentalists the ability to maximize success in expensive synthetic campaigns. Herein, we report an end-to-end data driven process to effectively predict how structural features of coupling partners and ligands impact Cu-catalyzed C–N coupling reactions. The established workflow underscores the limitations posed by substrates and ligands, while also providing a systematic ligand prediction tool that uses probability to assess when a ligand will be successful. This platform is strategically designed to confront the intrinsic unpredictability frequently encountered in synthetic reaction deployment.
Taming The Third Order Cumulant Approximation to Linear Optical Spectroscopy
Authors: Allan Luke , Zuehlsdorff Tim
Published: October 2023

The second order cumulant method offers a promising pathway to predicting optical properties in condensed phase systems. It allows for the computation of linear absorption spectra from excitation energy fluctuations sampled along molecular dynamics (MD) trajectories, fully accounting for vibronic effects, direct solute-solvent interactions, and environmental polarization effects. However, the second order cumulant approximation only guarantees accurate lineshapes for energy gap fluctuations obeying Gaussian statistics. A third order correction has been derived recently [J. Chem. Phys. {151}, 074111 (2019)], but often yields unphysical spectra or divergent lineshapes for moderately non-Gaussian fluctuations, due to the neglect of higher order terms in the cumulant expansion. In this work, we develop a corrected cumulant approach, where the collective effect of neglected higher order contributions is approximately accounted for through a dampening factor applied to the third order cumulant term. We show that this dampening factor can be expressed as a function of the skewness and kurtosis of the energy gap fluctuations and can be parameterized from a large set of randomly sampled model Hamiltonians for which exact spectral lineshapes are known. The approach is shown to systematically remove unphysical contributions in the form of negative absorbances from cumulant spectra in both model Hamiltonians and condensed phase systems sampled from MD, and dramatically improves over the second order cumulant method in describing systems exhibiting Duschinsky mode mixing effects. We successfully apply the approach to the coumarin-153 dye in toluene, obtaining an

Published: October 2023

Isotopes are at the foundation of applications in life science such as nuclear imaging and are essential tools for the determination of pharmacokinetic and dynamic profiles of new pharmaceuticals. However, the insertion of an isotope into an organic molecule remains challenging and current technologies are element-specific. Despite the ubiquitous presence of sulfur in many biologically active molecules, sulfur isotope labeling is an underexplored field and sulfur isotope exchange has been overlooked. In this work, we explore a nickel-catalyzed reversible carbon-sulfur (C-S) bond activation strategy to achieve selective sulfur isotope exchange. This approach enables to move beyond standardized element-specific procedures and was applied to multiple isotopes, including deuterium, carbon-13, sulfur-34 and radioactive carbon-14. These results provide a unique platform for multiple isotope labeling and are compatible with a wide range of substrates, including pharmaceuticals. In addition, this technology proved its potential as isotopic encryption device of organic molecules.
Size Matters: Computational Insights into the Crowning of Noble Gas Trioxides
Authors: Dash Soumya Ranjan , Sharma Himanshu , Tiwari Mrityunjay K , Greb Lutz , Vanka Kumar
Published: October 2023

In pursuit of enhancing the stability of the highly explosive and shock-sensitive compound XeO3, we performed quantum chemical calculations to investigate its possible complexation with electron-rich crown ethers, including 9-Crown-3, 12-Crown-4, 15-Crown-5, 18-Crown-6, and 21-Crown-7, as well as their thio analogues. Furthermore, we expanded our study to other noble gas trioxides (NgO3), namely KrO3 and ArO3. The basis set superposition error (BSSE) corrected binding energies for these adducts range from -13.0 kcal/mol to -48.2 kcal/mol, which is notably high for σ-hole mediated non-covalent interactions. The formation of these adducts was observed to be more favorable with the increase in the ring size of the crowns and less favorable while going from XeO3 to ArO¬3. A comprehensive analysis by various computational tools such as the mapping of the electrostatic potential (ESP), Wiberg bond indices (WBIs), Bader’s theory of atoms-in-molecules (AIM), natural bond orbital (NBO) analysis, non-covalent interaction (NCI) plots, and the energy decomposition analysis (EDA) analysis revealed that the C-H….O interactions, as well as dispersion interactions play a pivotal role in stabilizing adducts involving larger crowns. A noteworthy outcome of our study is the revelation of a coordination number of 9 for xenon in the complex formed between XeO3 and the thio analogue of 18-Crown-6, which is higher than the largest number reported to date.

Published: October 2023

Applications in health diagnostics, community safety and environmental monitoring require selective and quantitatively accurate active viral load assessment. Herein, we report a microfluidic enrichment strategy to separate intact SARS-CoV-2 particles by the AND logic gate with the inputs of cholesterol oligonucleotides for the envelope and aptamers for the spike. Considering the unequal quantity of endogenous spike and lipid membrane on SARS-CoV-2, a dual-domain binding strate-gy based on two aptamers targeting two spike domains was applied to balance the spike-envelope stoichiometric ratio. With the stoichiometric balanced DNA computation and the promoted microscale mass transfer of herringbone chip, the devel-oped strategy enables sensitively detection of pseudotyped SARS-CoV-2 with a limit of detection as low as 34 active virion/μL, but also distinguishes from their inactive counterparts, other nontarget viruses and free spike. Moreover, the captured viral particles can be released through DNase I treatment with up to 90 % efficiency, which is fully compatible with virus culture and sequencing. Overall, the developed strategy not only 100% identifies healthy donors (n = 8) and patients (n = 14) with SARS-CoV-2 infection, but also provides a novel perspective on regulating of stoichiometric ratio to achieve a more biologically appropriate DNA computation.
Reversible C=N Bond Formation Controls Charge-Separation in an Aza-Diarylethene Photoswitch
Authors: Sacherer Maximilian , Gracheva Sofia , Maid Harald , Placht Christian , Hampel Frank , Dube Henry
Published: October 2023

Diarylethene belong to the most eminent photoswitches and have been studied for many decades. They are found in virtually every field of applications and have become highly valuable molecular tools for instilling light-responsiveness into materials, catalysts, biological systems, or pharmacology. In this work we present a novel and distinct type of pyrimidine-based aza-diarylethene, which undergoes a highly unusual zwitterion-forming photoreaction. During this fully reversible process a CN double bond is established under concomitant aromatization and thiophene-ring opening. The metastable zwitterion thus possesses a positively charged extended aromatic structure and an appendant conjugated thiolate function. It can further photoisomerize between a more stable Z and a less stable E isomer, resulting in effective three-state photoswitching. Unusual for diarylethenes, the metastable isomers show negative solvatochromism and redshifted absorption in apolar solvents. Thermal stability of the zwitterions can be modulated from a dissipative to a highly stable behavior in response to pH, again in a fully reversible manner. Pyrimidine-based aza-diarylethene thus establishes a unique photoreaction mechanism for diarylethenes allowing to control charge separation, thermal stability, and color generation in a different way than hitherto possible.

This research highlights the role played by the media in the formation of inflation expectations among various respondents in Ukraine. Using a large news corpus and machine-learning techniques, I have constructed newsbased metrics that produce quantitative indicators for texts, which show if the news topics are relevant to inflation expectations. I have found evidence that various news topics may have an impact on inflation expectations, and can explain part of their variance. Thus, my results could help in the analysis of inflation expectations – which is of value, given that anchoring inflation expectations remains a key challenge for central banks.

Promoting cycling as a sustainable mode of transport necessitates understanding how individuals perceive the risks associated with bicycling based on age, gender, and riding experience. This study addresses a critical gap in the field of traffic by examining cyclists' perceptions of risk and safety on mixed-traffic roads. Despite increased interest in promoting cycling as a sustainable means of transportation, research on this topic is rare. Therefore, this study aims to contribute to existing literature on cyclist perceptions and cycling safety on roads with mixed traffic by examining the significant differences that may exist among age groups, genders, and individuals with varying riding experiences. The research focuses on roads lacking distinct bicycle paths and characterized by heterogeneous traffic streams. The study surveyed 120 cyclists on 13 roads in Pristina, the capital of Kosovo. Safety perception, measured using a Likert scale (1–5), was the dependent variable. Non-parametric methods, specifically the Mann-Whitney and Kruskal-Wallis tests, were employed to analyze the data and test the hypotheses. The results revealed statistically significant differences between genders (Mann-Whitney test: U = 720; Z = -5.887, p = 0.000 < 0.05; r = -0.537), between groups with and without riding experience (Mann-Whitney test: U = 1240.5; Z = -2.59; p = 0.01; r = -0.236), and among age groups (Kruskal Wallis test: df = 4; p = 0.022 < 0.05). With Bonferroni correction, post hoc analysis using the Mann-Whitney test demonstrated significant differences (adjusted p < 0.0125) between at least two age groups. The median perception of general safety was at Likert scale 3 (average safety), while the perception of comfort was at level 2 (uncomfortable). These findings provide valuable insights for policymakers involved in urban planning, offering targeted strategies to enhance cycling safety based on age, gender, and riding experience. The findings highlight the complicated interaction of these elements and their impact on riders' safety perceptions. By understanding these dynamics, policymakers and urban planners may build targeted interventions and infrastructure upgrades to promote safer and more inclusive riding environments. This work adds to the field by shining light on the elements that influence cyclists' risk perception, eventually guiding methods for improving cycling safety and boosting the use of bicycles as a sustainable transportation choice. Doi: 10.28991/CEJ-SP2023-09-011 Full Text: PDF

Published: October 2023

Among the political machines used by Prabowo's supporters is the hashtag #2019gantipresiden which has gone viral on sosial media, and has even become a news portal on an online site with the address www.2019gantipresiden.org. The researcher found three posts published by the portal raising political issues and basing opinions on the hadith of the prophet. One of these hadiths is "Muslims will experience a situation of being besieged and beaten up by other people like a tumpeng which is fought over by food champions" which is interpreted according to the condition of Muslims during the 2019 General Elections with political conditions castrated by people others through the government. Therefore, research on the meaning of political hadiths like this is very important to see whether shifts in the meaning of hadiths have been found since they were uttered or carried out by the prophet until the hadiths are voiced by parties who have political interests. In this research, the approach used to analyze the Prophet's hadith is Framing analysis by Robert N, Entman. The data analysis technique used by the author in this study is simantic framing analysis. In this case, simantic framing analysis is felt to be able to find out how the web www.2019gantipresiden.org carries out the process of framing news about the 2019 election using Robert N. Entman's analysis.Di antara mesin politik yang digunakan pendukung Prabowo adalah tagar #2019gantipresiden yang menjadi viral di media sosial, bahkan menjadi portal berita di situs online dengan alamat www.2019gantipresiden.org. Peneliti menemukan tiga postingan yang dimuat oleh portal tersebut dengan mengangkat isu politik dan melandasi opini dengan hadis nabi. Salah satu hadis tersebut adalah “umat Islam akan mengalami satu situasi dikepung dan dikeroyok oleh umat-umat lain seperti sebuah tumpeng yang diperebutkan oleh jago-jago makan” yang diinterpretasikan sesuai dengan kondisi umat Islam saat penyelenggaraan Pemilihan Umum 2019 dengan kondisi politik yang dikebiri oleh umat lain melalui pemerintah. Oleh karena itu, penelitian terhadap pemaknaan hadis-hadis politik seperti ini sangat penting untuk melihat apakah ditemukan pergeseran makna hadis sejak diucapkan atau dilakukan oleh nabi sampai hadis tersebut disuarakan oleh pihak yang memiliki kepentingan politik. Dalam penelitian ini model pendekatan yang akan digunakan menganalisa hadis Nabi adalah analisis Framing  Robert N, Entman. Teknik analisis data yang digunakan penulis dalam penelitian ini adalah analisis framing simantik.  Dalam hal ini, analisis Framing simantik dirasa mampu untuk mencari tahu bagaimana web www.2019gantipresiden.org melakukan proses pembingkaian berita seputar pemilu 2019 dengan menggunakan analisis Robert N. Entman.
