Supramolecular Modification of a Metal-Organic Framework Increases Flexibility and Switchability: Experimental Insights into Structural Deformation of ZIF-8
Authors: Tiba Al , Perman Jason , MacGillivray Leonard , Tivanski Alexei
Published: March 2022

Use of chemical modulators during the synthesis of a coordination framework is an important strategy to affect and tune properties of porous materials. Herein, we introduce an approach to understanding structural modulation and deformation of soft, porous crystals in the context of gas adsorption by using atomic force microscopy (AFM) nanoindentation and physisorption analysis. Modified nanocrystals of the prototypical zeolitic-imidazolate framework-8 (ZIF-8) were generated in triethylamine (Et3N) via an in-situ supramolecular modulation method. We demonstrate that using triethylamine as a modulator results in a conspicuous decrease in elastic modulus (0.7 ± 0.2 GPa) compared to the unmodified nanocrystals of ZIF-8 (2.1 ± 0.8 GPa). Argon gas adsorption analysis also reveals that the more flexible, amine-modified framework exhibited gradual and cooperative gate-opening structural transitions (P/P0 = 0.33 ± 0.02) compared to the steep and stepwise characteristics of unmodified samples of ZIF-8 (P/P0 = 0.45 ± 0.02). The differences in Argon gas pressure-induced structural deformations correspond to the decrease in elastic modulus of base-modified nanocrystals of ZIF-8, likely a consequence of the impact of Et3N on the relative number of point defects and hydrogen bonds in the framework. Our study demonstrates how a combination of AFM nanoindentation, gas uptake, and spectroscopic characterization can be applied to understand structural and energetic changes upon adsorption in flexible framework materials.

Published: March 2022

Understanding crystalline structures based on their chemical bonding is growing in importance. In this context, chemical bonding can be studied with the Crystal Orbital Hamilton Population (COHP), allowing to quantify interatomic bond strength. Here we present a new set of tools to automate the calculation of COHP and analyze the results. We use the program packages VASP and LOBSTER and the Python packages atomate and pymatgen. The analysis produced by our tools includes plots, a textual description, and key data in machine-readable format. To illustrate those capabilities, we have selected simple test compounds (NaCl, GaN), the oxynitrides BaTaO2N, CaTaO2N, and SrTaO2N, and the thermoelectric material Yb14Mn1Sb11. We show correlations between bond strengths and stabilities in the oxynitrides, as well as the influence of the Mn-Sb bonds on the magnetism in Yb14Mn1Sb11. Our contribution enables high-throughput bonding analysis and will facilitate the use of bonding information for machine learning studies.
Manganese-Porphyrin-Catalyzed C-H Fluorination: Hydrocarbons, But Not Drugs?
Authors: Vennelakanti Vyshnavi , Reilly Usa , Sinitskiy Anton
Published: March 2022

Transformation of C-H to C-F bonds in organic compounds can be used in drug design to easily diversify molecular series under exploration. A particularly attractive fluorination reaction is the recently discovered aliphatic C-H bonds fluorination catalyzed by manganese(Mn)-containing porphyrins, which proceeds under mild conditions and with high yields. However, this fluorination technique has been applied so far only to a narrow range of carbon rich organic substrates. In this preliminary study, based on quantum chemical modeling of several key stages in the presumed mechanism of this reaction, we put forward a hypothesis to explain difficulties of extending the Mn-porphyrin-catalyzed fluorination to nitrogen rich drug-like molecules, namely, a significant growth of the height of the activation barrier for drug-like substrates. Specifically, we demonstrate that reaction energies are comparable for various substrates, including those for which Mn-porphyrin-catalyzed fluorination occurs and those for which it does not occur, and hence, thermodynamic factors are unlikely to control the observed differences in the reactivity. Next, we carry out a first-pass modeling of fluorination reaction paths for two substrates, cyclohexane versus piperidine, as a representative of the type of nitrogen rich compound that can and cannot be fluorinated under recommended conditions, and found a significant difference in activation energies (~7 kcal/mol vs ~40 kcal/mol), which might point at the reason for the difference in the reactivity. Further computational modeling is required to reveal the limitations of the Mn-porphyrin-catalyzed fluorination, and, if possible, possible ways to overcome such limitations.
Site-Selective Hydrogenation of Electron-Poor Alkenes and Dienes Enabled by a Rh-Catalyzed Hydride Addition/Protonolysis Mechanism

Published: March 2022

The transition metal catalyzed hydrogenation of alkenes is a well-developed technology used on a lab scale as well as on large scales in the chemical industry. Site- and chemoselective mono-hydrogenations of polarized conjugated dienes remain challenging. Instead, stoichiometric main-group hydrides are used rather than H2. As part of an effort to develop a scalable route to prepare geranylacetone, we discovered that Rh(CO)2acac/xantphos based catalysts enable the selective monohydrogenation of electron-poor 1,3-dienes, enones, and other polyunsaturated substrates. D-labeling and DFT studies support a mechanism where a nucleophilic Rh(I)-hydride selectively adds to electron-poor alkenes and the resulting Rh-enolate undergoes subsequent inner-sphere protonation by alcohol solvent. The finding that (Ln)Rh(H)(CO) type catalysts can enable selective mono-hydrogenation of electron-poor (poly)enes provides a valuable tool in the design of related chemoselective reduction processes of unsaturated substrates.
Deciphering Distinct Overpotential Dependent Pathways for Electrochemical CO2 Reduction Catalyzed by an Iron-Terpyridine Complex
Authors: Loipersberger Matthias , Derrick Jeffrey , Chang Christopher , Head-Gordon Martin
Published: March 2022

[Fe(tpyPY2Me)]2+ ([Fe]2+) is a homogeneous electrocatalyst for converting CO2 into CO featuring low overpotentials of <100 mV, near-unity selectivity, and high activity with turnover frequencies faster than 100,000 s–1. To identify the origins of its exceptional performance and inform future catalyst design, we report a combined computational and experimental study that establishes two distinct mechanistic pathways for electrochemical CO2 reduction catalyzed by [Fe]2+ as a function of applied overpotential. Electrochemical data shows the formation of two catalytic regimes at low (hTOF/2 of 160 mV) and high (hTOF/2 of 590 mV) overpotential plateaus. We propose that at low overpotentials [Fe]2+ undergoes a two-electron reduction, two-proton transfer mechanism (electrochemical-electrochemical-chemical-chemical, EECC), where turnover occurs through the dicationic iron complex, [Fe]2+. Computational analysis supports the importance of the singlet ground state electronic structure for CO2 binding and that the rate-limiting step is the second protonation in this low-overpotential regime. When more negative potentials are applied, an additional electron transfer event occurs through either a stepwise or proton-coupled electron transfer (PCET) pathway, enabling catalytic turnover from the monocationic iron complex ([Fe]+) via an electrochemical-chemical-electrochemical-chemical (ECEC) mechanism. Comparison of experimental kinetic data obtained from variable controlled potential electrolysis (CPE) experiments with direct product detection with calculated rates obtained from the energetic span model support the PCET pathway as the most likely mechanism. Moreover, we build upon this mechanistic understanding to propose the design of an improved ligand framework that is predicted to stabilize the key transition states identified from our study and explore their electronic structures using an energy decomposition analysis. Taken together, this work highlights the value of synergistic computational/experimental approaches to decipher mechanisms of new electrocatalysts and direct the rational design of improved platforms

Calcium oxalate minerals of general formula CaC2O4.xH2O are widely present in nature and usually associated with pathological calcifications, constituting up to 70 – 80% of the mineral component of renal calculi. The monohydrate phase (CaC2O4.H2O, COM) is the most stable form, accounting for the majority of the hydrated calcium oxalates found. These mineral phases have been studied extensively via X-ray diffraction, IR spectroscopy and, to a lesser extent, using 1H, 13C and 43Ca solid-state NMR spectroscopy. However, several aspects of their structure and reactivity are still unclear, such as the evolution from low- to high-temperature COM structures (LT-COM and HT-COM, respectively), and the involvement of water molecules in this phase transition. Here, we report for the first time a 17O and 2H solid-state NMR investigation of the local structure and dynamics of water in the COM phase. A new procedure for the selective 17O- and 2H-isotopic enrichment of water molecules within the COM mineral is presented using mechanochemistry, which employs only microliter quantities of enriched water, and leads to exchange yields up to ~30%. 17O NMR allows both crystallographically inequivalent water molecules in the LT-COM structure to be resolved, while 2H NMR studies provide unambiguous evidence that these water molecules are undergoing different types of motions at high temperatures without exchanging with one another. Dynamics appear to be essential for water molecules in these structures, which have not been accounted for in previous structural studies on the HT-COM structure due to lack of available tools — highlighting the importance of such NMR investigations for refining the crystallographic data of biologically relevant minerals like calcium oxalates.
A polymer-based chemical tongue for the non-invasive monitoring of osteogenic stem-cell differentiation by pattern recognition of serum-supplemented spent media

Published: March 2022

The development of non-invasive techniques to characterize cultured cells is invaluable not only to ensure the reproducibility of cell research, but also for quality assurance of industrial cell products for purposes such as regenerative medicine. Here, we present a polymer-based ‘chemical tongue’, i.e., a biosensing technique that mimics the human taste system, that is capable of non-invasively generating fluorescence response patterns that reflect the proteins secreted, and also partially consumed, by cultured cells, even from serum-supplemented media containing abundant interferants. Analysis of the spent media collected during cell culture using our chemical tongue, which consists of cationic polymers of different scaffolds appended with environmentally responsive dansyl fluorophores, led to the successful (i) identification of human-derived cell lines, (ii) monitoring of the differentiation process of stem cells, even at the stage when conventional staining was negative, and (iii) detection of cancer-cell contamination in stem cells. Since the characterization of cultured cells is usually performed via invasive methods that result in cell death, our chemical-tongue approach, which is of high practical utility, will offer a new means of addressing the growing demand for highly controlled cell production in the medical and environmental fields.
The Intermolecular Interactions of Pyrene and its Oxides in Vacuum and in Toluene Solution
Authors: King Nathanael J. , Brown Alex
Published: March 2022

In this work, the Conformer-Rotamer Ensemble Sampling Tool, (CREST) with the underlying semi-empirical GFN2-xtb method was used for automated geometry exploration of the homodimers of pyrene, pyrene-4,5-dione, and pyrene-4,5,9,10- tetraone, along with the heterodimer of pyrene and pyrene-4,5,9,10-tetraone. Geometries and energies of the dimers were further refined at the ωB97X-D4/def2-TZVP level of theory, both in gas phase, and in toluene solution. Computations in solu- tions were handled using the CPCM (Conductor-like Polarizible Continuum Model) and SMD (Solvation Model based on Density) models. Two previously unidentified pyrene-homodimer conformations are identified, and the effects of oxidation on the geometries and energies of dimerization are explored; in general, oxidation leads to stronger intermolecular interactions, and decreased solubility in toluene. For selected dimers, DLPNO-CCSD(T)/cc-pVTZ/SMD(Toluene) energies are determined at the DFT geometries, and illustrate the accuracy of the ωB97X-D4 approach, with an MAD of 1.47 kJ/mol.

Published: March 2022

New heterometallic hydride complexes that involve the addition of {Mg–H} and {Zn–H} bonds to group 10 transition metals (Pd, Pt) are reported. The side-on coordination of a single {Mg–H} to Pd forms a well-defined σ-complex. In contrast, addition of three {Mg–H} or {Zn–H} bonds to Pd or Pt results in the formation of planar complexes with subtly different geometries. We compare their structures through experiment (X-ray diffraction, neutron diffraction, multinuclear NMR), computational methods (DFT, QTAIM, NCIPlot), and theoretical analysis (MO diagram, Walsh diagram). These species can be described as snapshots along a continuum of bonding between ideal trigonal planar and hexagonal planar geometries.

Herein, we report the use of sterically invariant carborane-based chalcogenols, containing exopolyhedral B-Se or B-S bonds, as ligands for the formation of photoluminescent copper(I)-based metal-organic chalcogenolate assemblies (MOCHAs). We show that precise tuning of the carborane dipole by changing the carborane isomer from meta- to ortho- allows for control over the MOCHA morphology and regulation of the resulting photophysical properties. Furthermore, microcrystal electron diffraction (MicroED) has been demonstrated as a powerful tool for metal chalcogenide structure elucidation. Through the use of MicroED, one of the isolated materials is determined to consist of zero-dimensional Cu4(Se-C2B10H11)4 clusters with an unprecedented Cu4Se4 geometry.

This study aims to determine toxic effects of polyester-based polymers (polycarbonate (PC), polyethylene terephthalate (PET) and, polybutylene terephthalate (PBT)) depending on physiological change in life cycle of Daphnia magna Straus (1820) (Cladocera, Crustacea). As a result of acute toxicity test, it was observed that although the rates of immobilized/dead organisms were low, damage started occurring in organisms. According to the results of 72th, the median effective concentration (EC50) values of PC, PET and PBT were determined as 2.604 mg L-1, 4.694 mg L-1 and >100 mg L-1, respectively. In consequence of chronic toxicity test, in the experiment set in which the water where daphnids were cultivated was used, it was observed that there was a high rate of deformation on daphnids which were exposed to ester-based polymers. The possible effect of polyester-based polymers on the daphnids deformation might be consequence of reaction between urea and ester groups of PC, PET, and PBT. Especially in the sets where microalgae existed and the natural conditions were simulated, it was determined that the toxicity response of daphnids varied in accordance with different microplastic types in terms of their chemical structure.

In the context of increased urbanization, urban green infrastructure (UGI) is an important tool for preserving the structure and functions of natural ecosystems and providing diverse benefits to the human population. The study of benefits is of high importance for the spatial and administrative planning of urban green infrastructures. The present analysis aims to understand the benefits associated with green infrastructures and to develop new possibilities for integrating green infrastructures into urban planning, using the municipality of Buzău as case study. In order to assess the distribution of UGIs in Buzău and to identify the benefits and services associated with them, 227 questionnaires were applied to local population. The case studies offer the possibility to provide concrete examples of current urban green infrastructures management practices. For the municipality of Buzău, the most desired elements of green infrastructure in the city is: parks and public gardens (94.20%), outdoor sports facilities (84.58%), street alignments (79.29%) and flower arrangements (55.06%). The involvement of the local community in the UGI planning process is a strong point, which should be integrated in the practices of local authorities and implemented effectively.

Flash floods have been in the centre of attention for numerous hydrological studies recently and their magnitude and frequency are projected to increase due to the changing climate. This is especially important in small catchments where a local storm event can cause rapid increase in damage causing discharges. To estimate the possible impacts of a rainfall event, it is necessary to understand the precipitation/runoff conditions. Soil Conservation Service Curve Number (SCS CN) method is widely used and discussed to estimate the effect of land cover and soil moisture conditions on runoff. In this paper, we implement this standard method in the Tajovský brook catchment in Central Slovakia. The individual land cover classes were identified, and weighted CN numbers were established. Forest accounted for 67% of the entire area, grasslands for 19% and built-up areas for 10%. The final CNII number was computed as 60.8. Seven initial abstraction ratio values were tested on a monthly hydrograph data and optimal value was set to 0.01. This suggests the possible most suited regional value of the abstraction ratio that could be used for this type of small (<50 km) forested catchments, but further testing on other catchments and precipitation events would be beneficial.

Published: March 2022

The forms of Cd, Pb, and Zn compounds in alluvial soils were studied on the basis of sequential chemical fractionation according to the modified Tessier scheme. It is established that most of the studied elements are fixed in the composition of strongly bonded compounds. When lead is contaminated, the initial ratio of the forms of Cd, Zn elements changes slightly, and Pb - significantly. Their accumulation in the most mobile forms is noted. The different ability of the studied soils to fix lead is shown. It is revealed that the main mechanism of lead fixation in polluted soils is ion exchange absorption.

The role of parent initiated motivational climate in athletes’ engagement and dispositional flow
Authors: Sarı İhsan , Bizan İlgim
Published: March 2022

The aim of this study was to investigate the role of parent-initiated motivational climate on athletes’ dispositional flow and sport engagement. For this purpose, a total of one hundred and eighty athletes (age, M=17.48, SD=3.39 years; sport experience, M=6.48, SD=3.75 years) voluntarily participated in this study. The participants were recruited voluntarily from team and individual sports. A personal information form, Parent-Initiated Motivational Climate Questionnaire-2, Athlete Engagement Questionnaire, and Short Dispositional Flow Scale 2 were used as the data collection tool. The data were analyzed by descriptive statistics, Pearson correlation analysis and stepwise multiple regression analysis. According to the Pearson correlation analysis, confidence, dedication, vigor, enthusiasm, global engagement, and dispositional flow were found to be positively and significantly correlated with parent-initiated task-involving climate. Parent-initiated ego-involving climate did not significantly correlate with any engagement or flow variables. According to the results of multiple regression analysis, parental task-involving climate significantly contributed to athletes’ confidence, dedication, vigor, enthusiasm, global engagement, and dispositional flow. Overall, the results showed that parents’ task-involving motivational climate contributed to athletes’ engagement and dispositional flow. In line with these findings some suggestions for parents are proposed.

Bryophytes are terrestrial plants and they contain many important medical aspects. In this study, six different bryophytes (Polytrichastrum formosum, Plagiomnium cuspidatum, Hypnum jutlandicum, Sphagnum palustre, Rhizomnium punctatum and Pellia epiphylla) were collected from Trabzon, Türkiye. The effect of the extract of these bryophytes on some human pathogenic microorganisms especially causing skin diseases (Staphylococcus aureus, Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus epidermidis, and Candida albicans) was investigated. The highest antimicrobial activity was obtained by P. formosum extract against S. aureus, B. cereus, E. coli, and S. epidermidis. P. epiphylla was also effective towards S. aureus, B. cereus, and S. epidermidis. No activity was obtained for C. albicans. MIC values of P. formosum, P. cuspidatum, R. punctatum, and P. epiphylla plant extracts were determined by using S. aureus, B. cereus, and S. epidermidis microorganisms. Because the plant with the lowest MIC values was P. epiphylla, soap and cream formulations were prepared using the extract of this plant. Antimicrobial properties of suspended soap/cream samples were determined against B. cereus, S. aureus, and S. epidermidis microorganisms. It was observed that both soap and cream samples containing plant extract inhibited bacterial growth more than control samples of soap and cream.

生化需氧量（BOD5）和化学需氧量（CODCr）是水环境监测中重要的指标，而在化验分析过程中，这两项指标又有相对应的关系，如果掌握不好其间的关系，会使我们得不到满意的结果。中国环境保护部发布HJ505—2009五日生化需氧量的测定稀释与接种法的标准中，对于二者之间的关系给予明确说明。在进行这两项指标实际分析时，生化需氧量往往不好确定稀释倍数，导致生化需氧量（BOD5）数据不准或无效，这时我们就参考一下化学需氧量（CODCr）的数值来确定BOD5的稀释倍数来做，这样就会提高BOD5数据准确度。为了确定二者之间的关系，这里做7组地表水的BOD5和CODCr7组废水的BOD5和CODCr来判断他们的系数关系。

Utility of the surgical Apgar score in predicting morbidity and mortality: A prospective study
Authors: Huliyappa Harsha , Ramachar Sreevathsa
Published: March 2022

Introduction

Optimization of postoperative care is often contingent upon the risk stratification tools such as surgical scores that are used to prognosticate potential complications.

Aim

This study evaluates the utility of surgical Apgar score (SAS) as a tool to predict morbidity and 30-day mortality among patients post general surgical procedures.

Material and methods

The study cohort comprised of 400 patients aged between 15 to 75 years, and prospectively undergoing emergency or elective general surgery. SAS of patients were extracted from the anesthesiologist’s records on estimated blood loss, lowest heart rate and lowest mean arterial pressure. Post-operative outcomes such as major complications and mortality within 30 days of surgery were monitored.

Results and Discussion

Out of the 297 elective procedures, 22 (7.41%) cases had major complications. While among those undergoing emergency surgeries (103), 38 (36.86%) patients developed major complications. The odds of developing major complications in patients with the high-risk SAS scores (31; 51.67%) was 5.42 (CI: 3.03–9.70) times greater than in patients with low-risk SAS scores (29; 48.33%). The odds of expiring after a general surgery was 11.92 times higher in high-risk patients (9; 75%) when contrasted with low-risk patients (3; 25%). The sensitivity and specificity of SAS in predicting major complications is 51.67% and 83.53%, respectively. The sensitivity and specificity of SAS in predicting mortality are 75% and 79.9%, respectively.

Conclusions

SAS serves as a simple and dependable tool to predict morbidity and 30-day mortality in patients undergoing surgical procedures under anesthesia other than local, requiring intensive perioperative monitoring.

Authors: Horvath Andrea , Stróżyk Agata , Szajewska Hania , Dziechciarz Piotr
Published: March 2022

Introduction

A better understanding of current infant feeding practices and factors influencing them may improve the implementation of infant feeding guidelines in the future.

Aim

To assess the confidence in knowledge and knowledge of selected infant feeding statements, and to assess selected infant feeding practices among parents of infants aged 4 to 12 months.

Material and methods

A cross-sectional study was conducted in Poland. Self-selected parents were recruited through the Internet. Data from 6934 responders, almost exclusively (99.2%) mothers, were analysed.

Results and discussion

Almost 68.8% of mothers assessed their knowledge of infant complementary feeding practices as sufficient. In line with current recommendations, most mothers agreed that fruits are a good source of vitamins for infants (75.3%); and disagreed that fruit juices should be given to infants younger than age 1 year (61.1%); plant-based beverages are an appropriate alternative to breast-milk substitutes for infants (59.9%); potentially allergenic foods should be included into infant diet only after other complementary food had been introduced (68.4%), and, the introduction of other potentially allergenic foods should be delayed, if symptoms following the introduction of a new food occur (55.7%). However, some participants, albeit minority, reported the introduction of plant-based beverages (12.5%), cow’s milk (16.7%), and fruit juices to infants younger than 12 months (15.8%), thus, it was against the current recommendations.

Conclusions

A discrepancy exists between the confidence in knowledge and knowledge of selected infant feeding statements and feeding practices among Polish mothers of infants aged 4 to 12 months.

Published: March 2022

This study aim to observe a legal rationale regarding a legal-system implementation of Dayak Ngaju customary dispute reconciliation in Kuala Kurun, Gunung Mas Regency, Central Kalimantan Province. In practice, the researchers found a combination performed autonomously in the legal system. Such combination was a society’s belief in using both customary legal system and positive legal system. The idea of this combination was underlined by a reflection of legal rationale finding two legal systems (customary and positive) functioned respectively where suitability occurred between legal culture of living law and formal law. The principle of a combination of legal system was an evidence of a new insight or a new paradigm through factual and norm elaborations from Dayak Ngaju customary divorce reconciliation case. This study used descriptive and analytical qualitative research method on the phenomenon of Dayak Ngaju customary dispute reconciliation in Central Kalimantan. The result obtained was implementation of a legal combination (both customary and national), instead of only an effort of a harmonization. However, the result show that implementation was not practically able to replace a naturalist paradigm, yet both were believed by the society to be able to achieve philosophical goal of a law, a peace.

Asphalt is a material that has non-volatile properties and softens gradually when heated and functions as a binder for aggregates and as a surface covering material to make it impermeable to water. However, asphalt also has a weakness. Namely, it is easy to crack and be damaged when vehicles pass through the main road. To overcome cracked and worn roads, it is necessary to test the ductility of asphalt so that the road becomes flexible/plastic. This ductility test is very important because it greatly affects the pavement layer; Therefore, a ductility test is needed to determine the level of plasticity of an asphalt. The asphalt ductility test method refers to the specifications of ASTM D113 – 07 and SNI 2432:2011 with 3 samples of test objects and a test instrument called a ductilometer of type TAS – 250. Based on the ductility test, the asphalt ductility reaches an average elongation of 117.33 cm; This value indicates that the plasticity level of the asphalt has met the specifications and can be used in sustainable pavement construction layers because it has good plasticity.
