AbstractIn Florida, multiple counties restrict the application of N to turfgrass and landscapes during the summer rainy season. These summer fertilizer blackout periods could impact turfgrass quality and the functionality of warm‐season turfgrass species. A 2‐year study was conducted at the University of Florida's Fort Lauderdale Research and Education Center (FLREC) and West Florida Research and Education Center (WFREC) to assess turfgrass performance of ‘Floratam’ and ‘Classic’ St. Augustinegrass [Stenotaphrum secundatum (Walter) Kuntze] as well as ‘Empire’ and ‘Palisades’ zoysiagrass (Zoysia japonica Steud.), respectively, receiving no N fertilization during summer blackout period using eight fertilization programs compared to an unfertilized control. Visual quality, normalized difference vegetation index, percentage green cover, and dark green color index were assessed biweekly. Roots were collected before and after the fertilizer blackout period to determine root dry weight. While no differences were detected in St. Augustinegrass at the FLREC and zoysiagrass at the WFREC, all fertilized treatments except urea reached and maintained an acceptable turfgrass quality (≥6) throughout the blackout period, suggesting that urea by itself was not sufficient to support an optimal turfgrass performance during a fertilizer blackout period. The addition of P to nutrition programs did not influence turfgrass quality. Results indicate that N source is the most important factor to sustain turfgrass quality year‐round in Florida.

AbstractHerein, we report two distinct octaphyrins obtained by the condensation of new dithieno[3,2‐b:2’,3’‐d]pyrrole based tetrapyrrane under two different acidic conditions. Fourfold meso‐substituted octaphyrin was the major product when the reaction was performed in the presence of an aryl aldehyde using trifluoroacetic acid. Whereas, the sixfold meso‐substituted octaphyrin was obtained when the precursor was condensed with pentafluorobenzaldehyde using para‐toluenesulfonic acid. Such a template effect of aryl aldehydes in oxidative coupling reactions is realized for the first time in literature. Experimental and theoretical studies suggested that the oxidized form of fourfold meso‐substituted octaphyrin is 32π antiaromatic and undergoes proton‐coupled electron transfer (PCET) to the protonated form of 34π aromatic congener upon treatment with protic acids. Furthermore, small organic molecules such as alcohols and amines were also found to promote chemical reduction. Single crystal X‐ray structure revealed that the aromatic counterpart is highly planar and stabilized by several intermolecular H‐bonding and F−F interactions, leading to a large 3D supramolecular arrangement and exhibited colorimetric sensing for fluoride and hydroxide anions. On the other hand, sixfold meso‐substituted octaphyrin did not show (anti)aromatic features, PCET or anion sensing, but its intriguing absorption features associated with protonation could make it an ideal candidate for pH‐dependent bioimaging.

Published: December 2023

AbstractIn recent decades, many efforts have been devoted to studying reactions catalyzed in nanoconfined spaces. The most impressive aspect of catalysis in nanoconfined spaces is that the reactivity of the molecules can be smartly driven to disobey classical behavior. A green and efficient three‐component aza‐Darzens (TCAD) reaction using a catalytic amount of γ‐cyclodextrins (CDs) in water has been developed to synthesize N‐phenylaziridines. CDs effectively performed this reaction in an environmentally friendly setting, achieving good yields. The same reaction was then performed using polymeric γ‐CD such as a γ‐cyclodextrin polymer crosslinked (GCDPC) with epichlorohydrin, a sponge‐like macroporous γ‐cyclodextrin‐based cryogel (GCDC), and a γ‐cyclodextrin‐based hydrogel (GCDH). The homogeneous and heterogeneous catalyst recovery was then studied, and it was proved to be easily recycled several times without relevant activity loss. Water, as a unique and eco‐friendly reaction medium, has been utilized for the first time, to the best of our knowledge, in this reaction. The inclusion of the reagents in CDs has been studied and rationalized by NMR spectroscopy experiments and molecular modeling calculations. The credit of the presented protocol includes good yields and catalyst reusability and precludes the use of organic solvents.

Published: December 2023

AbstractIn the present work, a transition metal‐based ternary oxide of NiMoO4 nanomaterials is prepared by both hydrothermal and solvothermal methods with various synthesis conditions. Structural evolution as a function of increase in calcination temperature is also discussed. Scanning electron microscope (SEM) analysis presents the surface morphology of as‐prepared samples with an apparent change in the particle size under different synthesis conditions. Energy Dispersive X‐ray spectroscopy (EDAX) analysis confirms the chemical composition of the nanomaterials. Structural analysis by X‐Ray powder Diffraction (XRD) exhibits the formation of 𝛼 and β‐phase of NiMoO4 and further pure 𝛼‐phase is observed at calcination temperature of 650 °C. Fourier Transform Infrared spectroscopy (FTIR) indicates various functional groups present in NiMoO4 sample. UV–vis absorption spectra present a broad peak around 220–450 nm. A direct and indirect energy band gap of ≈2.2 and ≈1.9 eV, respectively is calculated for NiMoO4 nanomaterials synthesized at 180 and 220 °C for 24 h and calcinated at 650 °C. NiMoO4 nanomaterials and their composites find an application as electrode materials in supercapacitor.

AbstractCurrent DES pretreatment is often performed under relatively severe conditions with high temperature, long time, and high DES usage. This work studied a short‐time diol DES (deep eutectic solvent) pretreatment under mild conditions to fractionate the bamboo, facilitate enzymatic hydrolysis, and obtain high‐quality lignin. At an optimized condition of 130 °C for only 10 min, lignin and xylan removal reached 61.34 % and 84.15 %, with residual glucan showing a ~90 % enzymatic hydrolysis yield. Equally important, the dissolved lignin could be readily recovered with 97.51 % yield, exhibiting 96.65 % β‐O‐4 preservation. The fractionation and lignin protection mechanisms were unveiled by XRD, FTIR, cellulose‐DP, 2D HSQC NMR, 31P NMR and GPC analysis. This study highlighted that short‐time fractionation of bamboo can be achieved by a diol‐based DES which is an ideal strategy to upgrade the lignocellulose biomass for high enzymatic hydrolysis yields and high‐quality lignin stream.

AbstractHaving in mind the remarkable economic and environmental issues involved in the presence of nickel and cobalt metals in electrode compositions, new Na0.67Mg0.05Fe0.1NixMn0.85‐xO2 (x=0.0, 0.05, 0.1, 0.15) with a P2 type layered structure, are synthesized to be essayed as positive electrodes in sodium‐ion batteries. The sol‐gel route here proposed favors the obtention of highly pure and crystalline samples with a homogeneous distribution of the constituting elements. Both galvanostatic and voltammetric tests reveal a superior electrochemical behavior for the Ni‐free sample, which delivers 94 mA h g−1 at 5C. This excellent performance is associated with a good kinetic response in terms of low charge and discharge hysteresis, high Na+ diffusivity, and low cell resistance. Ex‐situ measurements evidenced the combined contribution of both the reversible electrolyte insertion and the formation of peroxo species. These advantageous properties allow this electrode to reach a remarkable behavior when is cycled either to low temperatures or high rates.

SummaryThe placenta plays a pivotal role in the maintenance of normal pregnancy, but how it forms, matures, and performs its function remains poorly understood. Here, we describe a novel mouse line (Prl3d1‐iCre) that expresses iCre recombinase under the control of the endogenous prl3d1 promoter. Prl3d1 has been proposed as a marker for distinguishing trophoblast giant cells (TGCs) from other trophoblast cells in the placenta. The in vivo efficiency and specificity of the Cre line were analyzed by interbreeding Prl3d1‐iCre mice with B6‐G/R reporter mice. Through anatomical studies of the placenta and other tissues of Prl3d1‐iCre/+; B6‐G/R mouse mice, we found that the tdTomato signal was expressed in parietal trophoblast giant cells (P‐TGCs). Thus, we report a mouse line with ectopic Cre expression in P‐TGCs, which provides a valuable tool for studying human pathological pregnancies caused by implantation failure or abnormal trophoblast secretion due to aberrant gene regulation.

AbstractDetailed information about the historical range of variability in wildfire activity informs adaptation to future climate and disturbance regimes. Here, we describe one of the first annually resolved reconstructions of historical (1500–1900 ce) fire occurrence in coast Douglas‐fir dominated forests of the west slope of the Cascade Range in western Oregon. Mean fire return intervals (MFRIs) across 16 sites within our study area ranged from 6 to 165 years. Variability in MFRIs was strongly associated with average maximum summer vapor pressure deficit. Fire occurred infrequently in Douglas‐fir forest stands seral to mountain hemlock or silver fir, but fire frequency was much shorter than predicted by theory in other forest types. MFRIs within Douglas‐fir stands seral to western hemlock or grand fir ranged from 19 to 45 years, and MFRIs in stands seral to Douglas‐fir ranged from 6 to 11 years. There was little synchrony in fire occurrence or tree establishment across 16 sites separated by 4 km. The lack of synchrony in fire suggests that large, wind‐driven fire events that are often considered to be characteristic of coast Douglas‐fir forests were not an important driver of succession in our study area during the last ~400–500 years. Climate was more arid than normal during fire years in most forest types, but historical fire in stands seral to Douglas‐fir was strongly associated with antecedent moisture and less strongly associated with drought. We interpret the extraordinary tempo of fire we observed in stands seral to Douglas‐fir and the unique climate pattern associated with fire in these stands to be indicative of Indigenous fire stewardship. This study provides evidence of far more frequent historical fire in coast Douglas‐fir forests than assumed by managers or scientists—including some of the most frequent fire return intervals documented in the Pacific Northwest. We recommend additional research across the western Cascades to create a comprehensive account of historical fire in highly productive forests with significant cultural, economic, and ecological importance.

AbstractSodium–glucose cotransporter‐2 inhibitors (SGLT2is) reduce morbidity and mortality for heart failure (HF) patients and are recommended as cornerstones for their medical therapy. Utilization in clinical practice remains low for multiple reasons, one of which may be adverse events. We investigated the incidence of these events to see if they are associated with SGLT2i use. A systematic search was performed in databases, including PubMed, Embase, Cochrane Library, Clinicaltrials.gov, and WHO's International Clinical Trials Registry Platform. Relevant randomized controlled trial studies assessing the safety outcomes of SGLT2i in HF patients were included in this study. We conducted the common‐effect meta‐analysis to estimate the relative risk (RR) and 95% confidence interval (CI) of safety outcomes in SGLT2i compared with placebo. Eighteen studies were included in the meta‐analysis composed of 12 925 HF patients taking an SGLT2i and 12 747 taking a placebo. The meta‐analysis indicated that the all‐cause mortality and serious adverse events (SAEs) were lower in the SGLT2i group (RR, 0.91; 95% CI, 0.85–0.97; P = 0.005, I2 = 0%; and RR, 0.92; 95% CI, 0.90–0.95; P < 0.001, I2 = 43%, respectively). Volume depletion and genitourinary infections were more prevalent in the SGLT2i group (RR, 1.17; 95% CI, 1.06–1.28; P = 0.001, I2 = 0%; and RR, 1.27; 95% CI, 1.13–1.43; P < 0.001, I2 = 17%, respectively). Our meta‐analysis demonstrated that using SGLT2is in HF patients was correlated with reduced mortality and SAEs, with a more prominent effect in HF with reduced ejection fraction patients and those taking dapagliflozin.

AimBlood urea nitrogen (BUN) to creatinine ratio is associated with worse outcomes in acute heart failure (HF) but little is known about its importance in chronic HF.Methods and resultsWe combined individual patient data from clinical trials (HF with reduced ejection fraction [HFrEF]: PARADIGM‐HF, ATMOSPHERE and DAPA‐HF, and HF with preserved ejection fraction [HFpEF]: PARAGON‐HF and I‐PRESERVE). The primary outcome examined was a composite time to first HF hospitalization or cardiovascular death; its components and all‐cause death were also examined. Each HF phenotype was categorized according to median BUN/creatinine ratio, generating four groups that is, HFpEF ≤ and >median BUN/creatinine ratio and HFrEF ≤ and >median BUN/creatinine ratio. The association between BUN/creatinine ratio and outcomes was evaluated using the Kaplan–Meier estimator and Cox proportional hazard models. Overall, 28 820 patients were analysed. The median (IQR) BUN/creatinine ratio was 20.1 (Q1–Q3 16.7–24.7) in HFpEF and 18.7 (15.2–22.8) in HFrEF. In both HFpEF and HFrEF, higher BUN/creatinine ratio was associated with older age, female sex, and diabetes, but similar estimated glomerular filtration rate (eGFR). The risk of each outcome examined was significantly higher in patients with BUN/creatinine ratio ≥median, compared to <median, even after adjustment for other prognostic variables, including N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) and eGFR.ConclusionHigher BUN/creatinine ratio was associated with worse outcomes in patients with chronic HF across the spectrum of left ventricular ejection fraction, independently of eGFR and NT‐proBNP. BUN/creatinine ratio may reflect neurohumoral activation (especially increased arginine vasopressin), altered renal blood flow or other pathophysiologic mechanisms not incorporated in conventional prognostic variables.

AbstractNew coordination compounds made of two novel tetrazole and C,N‐bipyrazole ligands, 2‐(3,5,5′‐trimethyl‐1′H‐[1,3′‐bipyrazol]‐1′‐yl)acetonitrile (L1), and 1′‐((1H‐tetrazol‐5‐yl)methyl)‐3,5,5′‐trimethyl‐1′H‐1,3′‐bipyrazole (HL2), were prepared and fully characterized by spectroscopic techniques. Their crystal structures were identified by single‐crystal X‐ray diffraction revealing mononuclear complexes: [Ni(L1)3](ClO4)2 (1), [Cd(L1)2Cl2] (2), [Cu(HL2)(L2)]ClO4 (3), [Cu(L2)2] (4) and a dinuclear complex [Co2(HL2)(L2)Cl3] (5) comprising CoII ions in octahedral and tetrahedral surrounding within the same unit. Noticeably, 3 and 4 show different architectural structures due to ligand deprotonation as well as the effect of the counter anion. All compounds demonstrated antimicrobial activity against Gram (+) bacteria Listeria innocua and Staphylococcus aureus, as well as Gram (−) bacteria such as Escherichia coli and Pseudomonas aeruginosa, and antifungal activity against pathogenic fungi Geotrichum candidum, Aspergillus niger, and Penicillium crustosum. Interestingly, a high inhibition activity of 97 % was reached for 5 with a low concentration of only 81.1 μmol/L against Fusarium oxysporum f. sp. Albedinis, which is commonly damaging palm trees crops.
Advances in Nanohybrid Membranes for Dye Reduction: A Comprehensive Review
Authors: Taheri Mahsa 
Published: December 2023

AbstractSeparating valuable materials such as dyes from wastewater using membranes and returning them to the production line is a desirable environmental and economical procedure. However, sometimes, besides filtration, adsorption, and separation processes, pollutant destruction also can be suitable using photocatalytic membranes. The art of producing nanohybrid materials in contrast with nanocomposites encompasses nanomaterial synthesis as a new product with different properties from raw materials for nanohybrids versus the composition of nanomaterials for nanocomposites. According to the findings of this research, confirming proper synthesis of nanohybrid is one challenge that can be overcome by different analyses, other researchers' reports, and the theoretical assessment of physical or chemical reactions. The application of organic‐inorganic nanomaterials and frameworks is another challenge that is discussed in the present work. According to the findings, Nanohybrid Membranes (NHMs) can achieve 100% decolorization, but cannot eliminate salts and dyes, although the removal efficiency is notable for some salts, especially divalent salts. Hydrophilicity, antifouling properties, flux, pressure, costs, usage frequency, and mechanical, chemical, and thermal stabilities of NHMs should be considered.

Published: December 2023

AbstractClimate change no longer involves and affects just a few people or communities. However, most of them need climate change detection studies to adapt to the current and future climate conditions efficiently. The present research aimed to detect climate changes by considering the shift in climate conditions from one region to another over different periods based on a similarity index in the Carpathians basin using the new ClimShift toolbox, specially created for this purpose. Developed in R, based on the cosine similarity index and using a set of 32 climate indices (temperature and precipitation), ClimShift uses NC raster format (NetCDF files) as input data. The application is compatible with Microsoft and Unix/Linux environments. The toolbox allows the detection of forward and backward climate shifts. The results can be employed as a Climate Service and are extremely helpful for an efficient process of adaption to climate changes at a local/regional scale. A user‐friendly interface and a tutorial on how to use the toolbox are also available. The toolbox was tested for four locations in the Carpathians Basin (Vienna, Bekes, Cluj‐Napoca and Kosice) using 1961–1990 as a base period and 1991–2021 as an analysis period for the forward climate shift analysis. For Cluj‐Napoca, the application was also tested for the backward climate shift, using 1991–2021 as the base period and 1961–1990 as the analysis period, identifying the region where present climate conditions were specific during the older period. The scientific results indicated a significant shift towards the east and northeast from the older period to the most recent one and a low percentage (6%–10%) in the overlapping area with highly similar conditions between the two periods.

AbstractDecreased long‐range temporal correlations (LRTC) in brain signals can be used to measure cognitive effort during task execution. Here, we examined how learning a motor sequence affects long‐range temporal memory within resting‐state functional magnetic resonance imaging signal. Using the Hurst exponent (HE), we estimated voxel‐wise LRTC and assessed changes over 5 consecutive days of training, followed by a retention scan 12 days later. The experimental group learned a complex visuomotor sequence while a complementary control group performed tightly matched movements. An interaction analysis revealed that HE decreases were specific to the complex sequence and occurred in well‐known motor sequence learning associated regions including left supplementary motor area, left premotor cortex, left M1, left pars opercularis, bilateral thalamus, and right striatum. Five regions exhibited moderate to strong negative correlations with overall behavioral performance improvements. Following learning, HE values returned to pretraining levels in some regions, whereas in others, they remained decreased even 2 weeks after training. Our study presents new evidence of HE's possible relevance for functional plasticity during the resting‐state and suggests that a cortical subset of sequence‐specific regions may continue to represent a functional signature of learning reflected in decreased long‐range temporal dependence after a period of inactivity.
