It is very important to use the green synthesis approach that uses living things and plants. Using the biogenic reduction technique, silver nanoparticles were synthesized from the R. aculeatus plant for this research. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy, X-ray diffraction (XRD), and UV-vis spectroscopy was used to characterize the produced AgNPs (FT-IR). After the In this study, R. aculeatus plant extract and biogenically formed AgNPs were investigated for their potential antibacterial, antibiofilm and anticancer abilities. AgNPs were characterised using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and UV-vis spectroscopy (UV-VIS). According to the Debye Scherrer formula, the particle size was found to be 32.56 nm. Disc diffusion and microdilution methods were used to investigate the antibacterial activity. In the disc diffusion study, the best results were obtained from the extract and AgNP. In the tests using plant extracts, Staphylococcus aureus ATCC 25923 showed the lowest antibiofilm activity, while Bacillus subtilis and Enterobacter aerogenes ATCC 13048 showed the highest activity. Salmonella infantis was most affected by AgNP, while Escherichia coli CFAI ATCC 25922 was least affected. Biogenically synthesised AgNPs were also investigated in cytotoxic activity studies. It was found to have the lowest concentration value on MCF-7 and HUVEC cell lines at the determined concentrations. The extract did not have any cytotoxic effect on MCF-7 cell line. HUVEC cell line showed the lowest cytotoxic activity of 10-3 g/mL. The antibacterial, antibiofilm and anticancer properties of R. aculeatus plant extract and biogenically produced AgNPs have been the subject of an important study. Furthermore, the comparison of the effects of plant extract and AgNPs on breast cancer cell lines and healthy cell lines provides a rich scientific material.

Published: May 2023

Se realizó un estudio etnoictiológico de los peces conocidos como ruyac bagri, (Pseudoplatystoma punctifer y P. tigrinum) con el pueblo Kichwa de la cuenca del Rio Curaray en la provincia de Pastaza (Amazonía central del Ecuador) con el objetivo de documentar aspectos de la topografía corporal, taxonomía, ecología y pesca de ambas especies. Se aplicaron entrevistas estructuradas y se hicieron representaciones gráficas con la participación de 23 personas. Los principales resultados obtenidos fueron que, de acuerdo con los conceptos taxonónomicos indígenas, hay dos especies de ruyac bagri con características morfológicas específicas. La topografía corporal de estos peces presentó 14 principales estructuras morfológicas externas. Estos bagres pertenecen al ayllu bagriguna, como grupo integrante de los yacu aycha o peces. Las dos especies son más abundantes en el Río Curaray y sus lagunas adyacentes en enero y septiembre. Ambas realizan migraciones desde Perú hasta las cabeceras del Curaray y del Río Villano. Los entrevistados reportaron 23 presas y 9 predadores para ambas especies. Estos peces son capturados principalmente con redes y líneas de anzuelos. Su tamaño de captura en el área de estudio oscila entre 60-150 cm de longitud. Estos resultados son concordantes con estudios ictiológicos realizados desde otros enfoques científicos, lo cual sugiere urgentemente la vinculación del conocimiento indígena en el manejo de las pesquerías y la conservación de la biodiversidad amazónica.

Published: May 2023

Using classical breeding, plant breeders envision a plant type whose yield they aim to enhance by selecting for individual traits to create model/ideal plants or ideotypes. The experiment was carried out as a randomized complete blocks design with four replications and 15 local rice cultivars, required were collected for using path coefficient analysis and mahalanobis distance analysis. The results revealed that the higher positive effect on paddy yield was determined by panicle weight and number of spikelet per panicle. The higher negative effect on paddy yield was determined by DFM and FT. The highest genetic distance was observed between cv. ‘Langroudi’ and cv. ‘Tarom Hashemi’ and the least one was between cv. ‘Gharib Reihani’ and ‘Ahlami Tarom’. Totally, all local cultivars were close to each other in terms of the genetic distance. This result shows that ideotype, this ideotype yield gap can be compensated. According to the findings, the high level of paddy-yield changes and contribution of each factor affecting it shows that with proper management, a significant part of this change can be compensated and lead to potential yield.

Published: May 2023

The experiment was carried out in Agricultural University - Plovdiv in the period 2014-2016 to study the evapotranspiration of common beans crop under different irrigation levels. The used variety was Dobrudzhanski 7. The experiment was set up by the block method in four repetitions. Data from the following variants are used: 1) without irrigation; 2) 25% of the optimum irrigation rate (25%m); 3) 50%m; 4) 75%m; 5) with full irrigation rate (100%m). An optimum irrigated bean spends 385 mm (total) water on average in the layer 0-60 cm. The reduction of irrigation rates decreases the total evapotranspiration from 7% to 23% on average. For the variants with maximum irrigation and irrigation with 25% reduction of irrigation rate, the maximum values of evapotranspiration are registered at the beginning of grain filling phase, reaching 5-6 mm/day. The high values of evapotranspiration (over 4 mm/day) were observed from the first to the third decade of July. The increase of water stress induced by reduction of irrigation rates is a reason for reaching evapotranspiration maximum values earlier with 1-2 decades. In the same time, it has a negative effect on evapotranspiration values. Evapotranspiration is formed between 85-96% in layer 0-60 cm of the whole one-meter soil layer. From 50 to 60% of evapotranspiration are consumed by the soil layer 0-20 cm, depending on the year conditions. The annual irrigation rate forms over ⅓ (37%) of evapotranspiration for the optimum irrigated beans, as with the reduction of the irrigation norms its contribution decreases in favor of the precipitation and the initial water supply.

Authors: Sheykhzadeh Mehrdad , Mobasser Hamidreza , Petrodi Elyas Rahimi , Rezvani Mohammad
Published: May 2023

Silicon (Si) and zinc (Zn) has been recognized as beneficial elements to improve rice (Oryza sativa L.) grain yield. The present study was aimed at investigating the effects of silicon and zinc foliar application at different growth stages on yield components, grain yield, and concentration of silicon and zinc in rice grain. The experiment design was a factorial two-factor randomized complete block design (RCBD) with three replications. Treatments included the fertilizers foliar application at 3 levels (Potassium silicate, Silicon nanoparticles, Zinc Oxide nanoparticles) and rice growth stages at 5 levels (T1: early tillering + middle tillering + late tillering + full heading stage; T2: middle tillering + late tillering + full heading stage; T3: late tillering + full heading stage; T4: late tillering; T5: full heading stage). The results indicated that the application of Si and Zn nanoparticles was superior to potassium silicate in terms of improving the yield components, yield and nutrients concentration in rice grain. Application of Si and Zn nanoparticles increased the grain yield by 7.4 and 4.5%, respectively, above the potassium silicate. Foliar application of nutrients in both T1 and T2 stages led to improved grain yield (7716 and 7700 kg.ha-1 , respectively). The highest Si concentration in grain was obtained by foliar application of nano-Si at the T1 and T2 stages (3.97 and 3.83%, respectively), while the maximum Zn concentration in grain was observed with the nano-Zn application at the T2 stage (21.67 mg.kg-1 ). In general, we suggest applying Si and Zn nanoparticles at the middle tillering + late tillering + full heading stages to improve the yield and rice grain fortifying.

Published: May 2023

Soil compaction is one of the major problems of the agricultural sector affecting negatively the soil structure and impedes plant root growth. Soil penetration resistance should be measured from many points of the production land to determine the effects of plant growth problems. Collection of soil penetration values from huge lands is time-consuming, tiring, and tedious for researchers. Also, the number of measured points to what extent will be sufficient to evaluation on whole production area is not clear. To eliminate this ambiguity, soil penetration values of the unmeasured points should be estimated to evaluate the whole land. Artificial Neural Networks (ANN) are one of the most popular mathematical computing and modeling method used to estimate unknown data with the help of known data. In this study, we collected 1603 samples of geographical position and soil penetration value from 40 cm depth within the 20 ha field. From the 1603 values, 24% records were selected for testing and the remaining 76% records were used for training. Soil penetration values of the unmeasured points were estimated using Generalized Regression Neural Network (GRNN), Multi-Layer Perceptron (MLP) and Radial Bias Function (RBF) methods in MATLAB. In addition to mean squared error (MSE), root mean square error (RMSE) and mean absolute error (MAE) has been also used for evaluation of prediction accuracy on these methods. RBF results showed very good agreement between the predicted and the measured real values of soil resistance (MSE: 0.1608; RMSE: 0.3717; MAE: 0.3682).

Natural spawning of the leopard grouper (Mycteroperca rosacea) was studied in captivity from 2004 to 2008 under natural photoperiod conditions. Fish spawned naturally in 2006, but only 90,000 unfertilized eggs were collected. A total of 43 and 27 spawning days were observed in 2007 and 2008, respectively. Spawning season began in March and lasted until May–June and was related to an increase in water temperature from 21.1 to 23.8 °C. The mean (SE) number of eggs released each day was 101,705 (13,876) in 2007 and 40,510 (7,874) in 2008, and the total number of eggs collected in 2007 and 2008 was 4.37 × 106 and 1.07 × 106, respectively. The number of eggs collected per month was not significantly different within each year (P > 0.05), although a significant difference was observed between 2007 and 2008 (P < 0.05). The annual relative number of eggs released was 288,750 eggs·kg–1 in 2007 and 72,919 eggs·kg–1 in 2008, and viable egg production was 184,800 eggs kg–1 in 2007 and 25,375 eggs kg–1 in 2008. The fertilization rate (%) of the eggs collected daily differed significantly throughout the spawning season of 2007 (P < 0.05). The fertilization rate also differed (P < 0.05) between 2007 (61.10%) and 2008 (32.30%). Statistical analysis of the 2 consecutive spawning seasons indicated no correlation between the fertilization rate and fecundity. The effect of the moon phase on spawning was also considered. The fish spawned at dusk before total darkness. Mean (SD) egg diameter was 864.0 ± 22.0 μm.

В бухгалтерских книгах массарии Каффы на протяжении 1374–1426 гг. зафиксированы траты на организацию праздников и ритуалов, связывающих между собой городские сообщества, светскую и духовную власть. Преподнесение свечей латинским церквям в дни памяти святых было обязанностью генуэзских правителей города — консула, викария и двух массариев. Обычай находит свои аналогии в статутах городов и корпораций Северной Италии, где он оформился как часть культа святого покровителя и как благочестивый дар церкви. Ежедневные мессы во дворце консула, традиции празднования Рождества, Богоявления, Пасхи, Пятидесятницы, дня св. Георгия и дня св. Иоанна Крестителя не менялись на протяжении по меньшей мере 70 лет, оставаясь незафиксированными в нормативных документах до 1449 г. Неизменными оставались назначения выплат из казны, а в случае с Комиссией милосердия – даже номинальные суммы. Религиозные ритуалы воспроизводили привычный образ жизни переселенцев, устанавливали распорядок дня и года, определяли взаимное положение светских властей, церкви и городских сообществ посредством символических обязанностей.

Model reference adaptive control for nonlinear time‐varying hybrid dynamical systems
Authors: L'Afflitto Andrea
Published: May 2023

This paper presents the first model reference adaptive control system for nonlinear, time‐varying, hybrid dynamical plants affected by matched and parametric uncertainties, whose resetting events are unknown functions of time and the plant's state. In addition to a control law and an adaptive law, which resemble those of the classical model reference adaptive control framework for continuous‐time dynamical systems, the proposed framework allows imposing instantaneous variations in the reference model's trajectory to rapidly steer the trajectory tracking error to zero, while retaining the closed‐loop system's ability to follow a user‐defined signal. These results are enabled by the first extension of the classical LaSalle–Yoshizawa theorem to time‐varying hybrid dynamical systems, which is presented in this paper as well. A numerical simulation shows the key features of the proposed adaptive control system and highlights its ability to reduce both the control effort and the trajectory tracking error over a classical model reference adaptive control system applied to the same problem.
Shifting Oxygen Evolution Reaction Pathway via Activating Lattice Oxygen in Layered Perovskite Oxide

Published: May 2023

Developing high‐performance oxygen evolution reaction (OER) catalysts are critical for the practical application of many electrochemical energy devices. In this study, taking layered perovskite oxide thin films as the model system, it is demonstrated that the OER pathway can be effectively shifted by activating lattice oxygen, leading to strongly enhanced intrinsic activity. The OER performance of Ruddlesden‐Popper (RP)‐phase cobaltite is significantly enhanced as Sr doping at the A site increases, which is attributed to the shift of the reaction pathway from adsorbate evolution mechanism (AEM) to lattice oxygen‐mediated mechanism (LOM). Advanced spectroscopic techniques and density functional theory calculations reveal that the Sr dopant effectively facilitates oxygen ligand hole formation, charge transfer from the oxygen sites, and the formation and migration of oxygen vacancy, hence promoting lattice oxygen to participate in surface reactions. The results provide critical insight into the role of oxygen activity and offer a potential way for constructing highly active electrocatalysts.
Azobenzene Functionalized Organic Covalent Frameworks: Controlled Morphologies and Photo‐Regulated Adsorption
Authors: Zhao Yanli , Tao Xinfeng , Lin Jiaping , Lin Shaoliang
Published: May 2023

Covalent organic frameworks (COFs) containing azobenzene building blocks carry great potential for use in intelligent storage, separation, chemical sensing, and catalysis due to their intriguing photo‐responsiveness. However, azobenzene units are often exploited as the linkers to form the framework of COFs, thereby restricting their molecular motion and photoisomerization. Herein, a simple yet robust template‐free solvothermal strategy is reported to yield azobenzene‐dangled COFs (Azo‐COFs) with their azobenzene moieties suspending within the pores. The crystallinity, specific surface area, and morphology of Azo‐COFs can be conveniently tailored by changing the ratio of amine to aldehyde monomers. Notably, the Azo‐COFs provide sufficient free space for the reversible trans‐to‐cis isomerization of the dangled azobenzene units inside the pores, thus reversibly regulating surface wettability of Azo‐COFs. The adsorption capacity of Azo‐COFs toward organic dye molecules is increased by 3.7‐fold when irradiated with ultraviolet light, which can be ascribed to the intelligent closing/opening of molecular gates rendered by photoisomerization of azobenzene moieties. As such, the ability to photoregulate the adsorption of Azo‐COFs highlights their significance in functioning as smart porous nanomaterials for applications in cargo release, molecular sieves, ion transport, energy conversion systems, and environmental remediation.

Conductive hydrogels (CHs) are regarded as one of the most promising materials for bioelectronic devices on human‐machine interfaces (HMIs). However, conventional CHs cannot conform well with complex skin surfaces, such as hairy or wrinkled skin, due to pre‐formation and insufficient adhesion; they also usually lack antibacterial abilities and require tissue‐harm and time‐consuming preparation (e.g., heating or ultraviolet irradiation), which limits their practical application on HMIs. Herein, an in situ forming CH is proposed by taking advantage of the PEDOT:PSS‐promoted self‐polymerization of zwitterionic [2‐(methacryloyloxy)ethyl]dimethyl‐(3‐sulfopropyl) (SBMA). The hydrogel is formed spontaneously after injection of the precursor solution onto the desired location without any additional treatments. The as‐prepared hydrogel possesses excellent elasticity (elastic recovery >96%), desirable adhesive strength (≈6.5 kPa), biocompatibility, and intrinsically antibacterial properties. Without apparent heat release (<5 °C) during gelation, the hydrogel can form in situ on skin. Additionally, the obtained hydrogel can establish tight contact with skin, forming highly conformal interfaces on hairy skin surfaces and irregular wounds. Finally, the in situ forming hydrogels are applied as conformal epidermal electrodes to record stable and reliable surface electromyogram signals from hairy skin (with high signal‐to‐noise ratio, SNR ≈ 32 dB) and accelerate diabetic wound healing under electrical stimulation.

The electron transport layer (ETL) plays a crucial role for efficiency and stability of perovskite solar cells (PSCs). As a promising low‐temperature ETL, tin oxide still requires complicated surface chemical decoration or heat‐treatments to further passivate the defects and adjust band energy level to improve the optoelectronic performance of the device. Herein, a novel and efficient strategy is developed for the solution prepared annealing‐free SnO2 ETL for PSCs. Through simple electrochemical regulation, the elemental composition, valence ratio of Sn, concentration of oxygen vacancies, hydroxyl groups, and dopant ions are precisely modified with the optimized the energy band, reduce the defect density, and enhance high carrier transport for PSCs. Thus, an increase of power conversion efficiency (PCE) from 21.6% to 24.7% and a high VOC of 1.19 V is obtained. The modified devices maintain 95% of the initial PCE after 2000 h of storage, and 80% of the initial PCE after 900 h of aging in an atmospheric environment at 75 °C and RH 20 ± 5%. Moreover, the perovskite solar module based on the as made SnO2 achieve a high PCE of 21.3%.

The growth of disordered lithium dendrite and the notorious reaction between Li and electrolyte hamper the practical application of Li metal batteries (LMBs). Herein, an artificial solid electrolyte interphase (ASEI) constructed by a nitro‐functionalized covalent organic framework (NO2‐COF) is designed to regulate Li+ deposition and stable Li anodes. Strong electron‐withdrawing nitro groups can gather the surrounding electrons of connected monomer by the donor‐acceptor (D‐A) effect, thus regulating the electron structure of the covalent organic framework (COF) and constructing a specific cation‐oriented channel. The uniform Li+ deposition and inhibition of Li dendrites are achieved under such a high‐selective Li+ transportation channel and regulated surface electric charge. In addition, the nitro can also be reduced to NO2− and further react with Li to produce high ionic‐conductivity Li3N and LiNxOy during the charging/discharging, which contributes to the migration of Li+. As a result, NO2‐COF‐modified symmetrical batteries realize an ultra‐long cycling life of more than 6000 h under a current density of 5 mA cm−2 compared to bare Li and TpBD‐COF/Li (without nitro). The full cells coupled with LiFePO4 stably cycle 1000 times with a capacity retention of 91%. Hence, effectively optimizing electron structure by the donor‐acceptor (D‐A) effect  provides a better platform to elevate the performance of LMB.
Multielectron Conversion: Peculiar Transition Metal Sulfides with Mixed Vulcanized States toward High‐Capacity Metal‐Ion Storage
Authors: Song Qianqian , Wu Ziyang , Wang Yun‐Xiao , Dou Shi Xue , Yang Jianping
Published: May 2023

Transition metal sulfides with mixed vulcanized states (TMS‐mVs) possess tremendous potential to realize highcapacity, superior redox reactions, and structural reversibility for metal‐ion (Mn+) storage owing to their multielectron reactions caused by the simultaneous participation of transition metal (TM) cations and S22−anions as well as multifarious TM or S valence states. Here, recent advances are systematically introduced regarding the mainstream TMS‐mVs that can be applied to Mn+storage. These TMS‐mVs can be divided into two categories of TMS, those with mixed sulfur‐valence states (TMS‐mSs) and those with mixed metal‐valence states (TMS‐mMs). It is found that TMS‐mV anodes mainly experience three reaction mechanisms, inculding insertion‐accompanied conversion, insertion, and conversion reactions. During the reversible charge process, Li2S is possibly oxidized into polysulfides or even S. TMS‐mVs have the ability to transfer more electrons than other homogeneous TMSs. TMS‐mS anodes usually present higher theoretical specific capacities than TMS‐mM anodes. In these TMS‐mV anodes, Mo‐based, V‐based, and Co‐based TMS‐mM anodes exhibit good electrochemical reversibility, Ni‐based TMS‐mM anodes exhibit moderate electrochemical reversibility, and Fe‐based TMS‐mM and TMS‐mS anodes exhibit poor electrochemical reversibility. The strategies for enhancement of their electrochemical performance are classified into composite, coating, nanostructure, heterointerface, and lattice engineering.

Plastic/ductile inorganic van der Waals (vdW) thermoelectric semiconductors offer transformative advantages for high‐performance flexible thermoelectric devices, which can displace the self‐charge system of wearable electronics. However, the chemical origin of their plasticity remains unclear. Here, it is reported that the exceptionally large plastic strain of the bulk SnSe2 crystal results from its polytype conversion under an external force. The SnSe2 single crystal consists of a large‐period polytype with 18R low‐symmetry structure rather than the trigonal and hexagonal‐phase that are frequently observed in the polycrystalline specimen. In situ applied pressure to the specimen drives a phase transition from low to high‐symmetry, that is, from 18R to 4H, and finally to 2H‐SnSe2. First principle calculations corroborate that the dynamic phase transition is a pressure‐activated process and only 15 MPa pressure erases their energy gaps, consistent with experimentally measured strain–stress curves. This dynamic phase transition results in superior and near isotropic plasticity along the direction parallel and perpendicular to the cleavage plane.

P‐type organic electrode materials are known for their high redox voltages and fast kinetics. However, single‐electron p‐type organic materials generally exhibit low capacity despite high operating voltage and stability, while some multi‐electron p‐type organic materials have high theoretical capacity but low stability. To address this challenge, we explore the possibility of combining single‐electron and multi‐electron units to create high‐capacity and stable p‐type organic electrodes. We demonstrate the design of a new molecule, 4,4′‐(10H‐phenothiazine‐3,7‐diyl) bis (N,N‐diphenylaniline) (PTZAN), which is created by coupling the triphenylamine molecule and the phenothiazine molecule. The resulting PTZAN||Zn battery shows excellent stability (2000 cycles), high voltage (1.3 V), high capacity (145 mAh g−1), and energy density of 187.2 Wh kg−1. Theoretical calculations and in/ex situ analysis reveal that the charge storage of the PTZAN electrode is mainly driven by the redox of phenothiazine heterocycles and triphenylamine unit, accompanied by the combination/release of anions and Zn2+.

Published: May 2023

Tetraethyl p‐xylenediphosphate is used as the organic ligand to prepare the organodiphosphonate Zr‐based metal organic frameworks (ZrP‐MOF). The physicochemical characterizations of ZrP‐MOF under different hydrothermal and calcination conditions were performed by various analytical techniques. ZrP‐MOF was then employed as a catalyst for the catalytic transfer hydrogenation of furfural with alcohol as the hydrogen donor, and the preparation parameters and catalytic properties of ZrP‐MOF were investigated. Compared with fresh ZrP‐MOF, the furfural conversion of ZrP‐MOF calcined at 825 K increased from 43.5% to 95.1%. Calcination can significantly increase the Lewis/Brønsted acid ratio and enlarge the pore structure of ZrP‐MOF, which promote the furfural catalytic transfer hydrogenation reaction over Zr‐O based on the Meerwein–Ponndorf–Verley reduction.

Key Clinical Message

To date, the pathogenic mechanisms of the association between Crohn's disease and MALT lymphoma are ambiguous and yet remain to be elucidated. The publication of other cases illustrating this rare association would be interesting to properly plan therapeutic strategies and to better understand the pathogenesis and the prognosis of this association.

Crohn's disease is a progressive disease, with increasing incidence, that leads to bowel damage and disability. Primary colonic MALT lymphoma is a low‐grade B lymphoma, representing only 2.5% of all MALT lymphomas. The pathogenesis of these two cancers is still not clearly elucidated and their association is rare. To our knowledge, only two cases have illustrated synchronous Crohn's disease and MALT lymphoma. The possible role of Crohn's disease as a precursor of MALT lymphoma is still debated; some studies proposed that immunosuppressive drugs used in Crohn's disease are involved in the lymphomagenesis of MALT lymphoma. Other studies supposed no relation between these two neoplasms.

We present a rare case of association between Crohn's disease and primary colonic MALT lymphoma in an elderly female patient who had not received any immunosuppressive therapy. The patient presented with chronic diarrhea, epigastric pain, and weight loss. A colonoscopy with biopsies was performed. The histopathologic examination concluded with the diagnosis of not only Crohn's disease but also MALT lymphoma. This discovery of MALT lymphoma was incidental. We highlight the clinical and histopathological features, and we discuss the association between Crohn's disease and MALT lymphoma, which may provide additional information about pathogenic mechanisms.
