The objective of the present study was to determine the composition in mineral elements, the antisickling activity and the osmotic brittleness test, of the twenty three extracts of two plants Cyttaranthus congolensis, Hypoxis angustifolia used in the management of sickle cell disease by the traditional healers in Kwilu province. Mineral composition analyses of these two plants were performed using X-ray fluorescence spectrometric method. Twenty three( 23) mineral elements were identified in each of these two plants among others: Potassium (K), Phosphorus (P), Calcium (Ca), Sodium (Na), Magnesium (Mg), Sulfur (S), Chlorine (Cl) and trace elements such as: Aluminum (Al), Silicon (Si), Vanadium (V), Chromium (Cr), Manganese (Mn), Iron (Fe), Nickel (Ni), Copper (Cu), Zinc (Zn), Selenium (Se), Bromine (Br), Molybdenum (Mo), Tin (Sn), Iodine (I), Barium (Ba) and Lead (Pb). Mineral elements related to sickle cell disease are: Iron (Fe), Zinc (Zn), Selenium (Se), Copper (Cu), Calcium (Ca), Magnesium (Mg) and Manganese (Mn). Of all these elements, Potassium and Calcium are in higher content while Lead, Tin, Bromine, Copper and Nickel are in trace amounts. The antisickling activity of Cyttaranthus congolensis and Hypoxis angustifolia extracts, was tested using the Emmel test. The results obtained showed a significant in vitro antisickling activity for both plants. The osmotic fragility test used to confirm the Emmel test showed that the hemolysis rate decreased with increasing NaCl concentration. In the presence of anthocyanins, the antihemolytic activity at different NaCl concentrations was higher than the control. This indicates the action of the extracts of these plants on the osmotic fragility of red blood cell membrane.

AbstractThe forecasting of crop yield is one of the most critical research areas in crop science, which allows for the development of decision support systems, optimization of nitrogen fertilization, and food safety. Many tested modeling approaches can be differentiated according to the models and data used. The models used are traditional crop models that require data that are often difficult to measure. New modeling approaches based on artificial intelligence algorithms have proven to be of high performance, flexible, and can be tested based on available data. In this study, four independent field experiments conducted onTriticum turgidumsubsp.durumDesf. in central–southern Italy were used to train a set of machine learning (ML) algorithms to predict the yield using 16 variables: fertilization, nitrogen management, pedoclimatic, and remote sensing data. Four ML algorithms were calibrated and validated over two independent sites, and a linear regression model was used as a control. The calibrated models can predict the grain yield in the two regions by using ancillary data, topsoil physical and chemical properties, multispectral drone imagery, climatic data, and nitrogen fertilizer applied at the site. Among the four ML algorithms, stochastic gradient boosting (root‐mean‐square error = 0.58 t ha−1) outperformed others during calibration and transferability. Nitrogen application rate, seasonal precipitation, and temperature are the most important features for predicting wheat yield.
Improved vapor pressure prediction from PR + COSMOSAC EOS using normal boiling temperature
Authors: Tsai Chang‐Che , Lin Shiang‐Tai 
Published: December 2022

AbstractWe evaluate the predictive power of the PR + COSMOSAC Equation of State (EOS) for vapor pressure using a large dataset of 19,081 compounds. The PR + COSMOSAC EOS uses results of quantum mechanical solvation calculations to determine the energy and molecular volume parameters in the Peng‐Robinson EOS and thus does not require experimental critical temperature (Tc), pressure (Pc), and acentric factor (ω) as in the conventional approach. The prediction accuracy (average absolute relative deviation) is 141%, about seven times that of the PR EOS. A new approach is developed to improve the prediction accuracy from PR + COSMOSAC EOS by incorporating experimental normal boiling temperature. The prediction accuracy improves to 58%, about three times that of the PR EOS. The PR + COSMOSAC EOS is an effective method for vapor pressure prediction when no or just some experimental data is available.

AbstractRegulating the microenvironment of active sites is crucial to boost the performance of direct propene epoxidation with H2 and O2. Herein, the enhanced surface transfer of H2O2 intermediates was first achieved by sodium‐decorated Au‐Ti bifunctional active sites. Combined with multi‐techniques (e.g., operando UV–vis–NIR system, DFT studies and quantitative model calculations), it is found that the sodium‐decorated silanols (Si‐ONa species) on the TS‐1 support enhance the formation of Ti‐OOH intermediates by restraining H2O2 decomposition. In addition, sodium‐decorated silanols improves the desorption of propylene oxide, suppressing its ring‐opening and formation for the carbonaceous deposits. Moreover, the sodium‐decorated Au nanoparticles with smaller diameter and higher electron density further strengthen O2 adsorption and boost the H2O2 formation. This work not only provides fundamental understandings on the microenvironment of Au‐Ti bifunctional catalysts but also sheds new light on enhancing the performance by boosting the surface molecular transfer.

Authors: Zhao Haorui , Song Yingze , Sun Jingyu 
Published: December 2022

AbstractOn account of high energy density and low cost of sulfur, lithium‐sulfur (Li−S) battery has been regarded as an appealing energy storage system to date. Nevertheless, it has faced formidable challenges, mainly pertaining to the fatal shuttle effect and retarded sulfur redox kinetics. Single atom catalysts (SACs) have showcased great promise for addressing these issues owing to their maximum atom utilization efficiency, favorable catalytic activity as well as their good structural tunability at an atomic level, considerably contributing to the recent fruitful advancements in Li−S realm. In this review, we summarize the state‐of‐the‐art strategies in the coordination manipulations of SACs toward highly efficient and durable Li−S batteries. The recent advances, existing issues, and future outlooks are discussed accordingly, aiming to guide the synthetic design of SACs, propel the underlying mechanism understanding and ultimately boost the commercial viability of Li−S batteries.

AbstractThe conventional method for analyzing fatty acid is gas chromatography (GC) with polar capillary columns. However, owing to the high cost and the sensitivity of these columns to the presence of water and oxygen, these columns are not the best choice for separation. Also, analyzing long‐chain acids (>C28) with polar columns is impossible. On the other hand, complete separation with nonpolar columns is not possible for some saturated, unsaturated and long‐chain fatty acids. Therefore, in this study, with the help of chemometric methods, a method was developed using GC/mass spectrometry (MS) with a nonpolar column to resolve the peaks to completely separate and accurately identify and quantify fatty acids. Using this method, the fatty acid profiles of the seed oils of Sesamum indicum L, Nigella sativa, Pimpinella anisum, Linum asitatissimum L, Silybum marianum and Amygdalus communis L. var. Amara and var. Dulcis were identified. Through applying the multivariate curve resolution method after GC/MS, the C‐18 fatty acids such as α‐linolenic, linoleic, oleic and stearic acids were separated and quantified. Also, the total percentages of identified fatty acids increased by 1–6% after resolving overlapping peaks. Finally, the obtained percentages of saturated and unsaturated fatty acids were confirmed by reference reports.

AbstractBackgroundApoptin is derived from the chicken anemia virus and exhibits specific cytotoxic effects against tumor cells. Herein, we found that Apoptin induced a strong and lasting endoplasmic reticulum (ER) stress response, Ca2+imbalance, and triggered the mitochondrial apoptotic pathway. The aim of this study was to explore the mechanisms by which Apoptin exhibited anti‐tumor effects in HepG‐2 cells.MethodsThe intracellular levels of calcium (Ca2+) were induced by ER stress and determined by electron microscopy, flow cytometry, and fluorescence staining. The mitochondrial injury was determined by mitochondrial membrane potential and electron microscopy. Western blotting was used to investigate the levels of key proteins in ER stress and the apoptotic pathway in mitochondria. The relationship between Ca2+levels and apoptosis in Apoptin‐treated cells was analyzed using a Ca2+chelator (BAPTA‐AM), flow cytometry, and fluorescence staining. We also investigated the in vivo effects of Ca2+imbalance on the mitochondrial apoptotic pathway using tumor tissues xenografted on nude mice.ResultsThis study showed that Apoptin induced a strong and long‐ lasting ER stress and injury, which subsequently led to an imbalance of cellular Ca2+levels, a reduction in the mitochondrial membrane potential, a significant extent image in the mitochondrial structure, and an increase in the expression levels of Smac/Diablo and Cyto‐C.ConclusionsIn summary, Apoptin induced apoptosis in HepG‐2 cells via Ca2+imbalance and activation of the mitochondrial apoptotic pathway. This study provided a new direction for antitumor research in Apoptin.

Nature and Strength of Weak O⋅⋅⋅O Interactions in Nitryl Halide Dimers
Authors: Petelski Andre Nicolai , Duarte Darío Jorge Roberto , Peruchena Nélida María 
Published: December 2022

AbstractThe use of real space functions and molecular graphs has pushed some chemists to wonder: Are interactions between negatively charged oxygen atoms possible? In this contribution we analyze whether there is a real interaction between oxygen atoms in nitryl halide dimers (XNO2)2 (X=F, Cl, Br and I) and in tetranitromethane and derivatives. Based on ab‐initio and density functional theories (DFT) methods, we show these complexes are weakly stabilized. Energy decomposition analyses based on local molecular orbitals (LMOEDA) and interacting quantum atoms (IQA) reveal both dispersion and exchange play a crucial role in the stabilization of these complexes. Electron charge density and IQA analyses indicate that the oxygen atoms are connected by privileged exchange channels. In addition, electrostatic interactions between O and N atoms are also vital for the stabilization of the complexes. Finally, a reasonable explanation is given for the dynamic behavior of nitryl groups in tetranitromethane and derivatives.
