Laboratory and greenhouse evaluation of four iron fertilizer sources
Authors: Goos R. Jay 
Published: October 2021

AbstractA relatively new iron fertilizer in the United States is FeHBED [Fe‐N,N′‐bis(2‐hydroxybenzyl)ethylenediamine‐N,N′‐diacetate], a chelate with a stability constant for ferric iron greater than FeEDDHA [Fe‐ethylenediamine‐N,N′‐bis(o‐hydroxyphenylacetate]. This study compared response of soybean [Glycine max (L.) Merr.] over two greenhouse cropping periods to FeHBED, FeEDDHA‐1 (∼80% ortho‐ortho isomer), FeEDDHA‐2 (∼50% ortho‐ortho isomer), and FeEDDHSA [Fe‐ethylenediamine‐N,N‐di([2‐hydroxy 5‐sulfophenyl])acetate]. FeHBED and FeEDDHA‐1 gave positive responses to all measured parameters (chlorophyll level, dry matter production, Fe uptake) that were not significantly different (.05 level) from each other for the two cropping periods. The two products were similar in performance. FeEDDHA‐2 and FeEDDHSA generally gave lesser responses than FeHBED or FeEDDHA‐1. The relative effectiveness of the four materials to increase dry matter or Fe uptake was predicted by a simple laboratory test, which measures the proportion of applied Fe remaining soluble after a 1‐wk incubation with soil.

AbstractThree‐dimensional ordered porous materials known as inverse opal films (IOFs) were synthesized using nanocrystals with precisely defined morphologies. Comprehensive theoretical and experimental studies of the volume fraction ratio and electrostatic interactions between nanocrystals and polystyrene templating particles enabled the formation of highly ordered crack‐free photonic structures. The synthetic strategy was first demonstrated using titanium dioxide (TiO2) nanocrystals of different shapes and then generalized to assemble nanocrystals of other functional materials, such as indium tin oxide and zinc‐doped ferrite. Tunable photocatalytic activity of the TiO2 IOFs, modulated through the choice of the shape of TiO2 nanocrystals in conjunction with selecting desired macroscopic features of the IOF, was further explored. In particular, enhanced activity is observed for crack‐free, highly ordered IOFs whose photonic properties can improve light absorption via the slow light effect. This study opens new opportunities in designing multi‐length‐scale porous nanoarchitectures having enhanced performance in a variety of applications.

Published: October 2021

AbstractUstYa family proteins (DUF3328) are widely and specifically distributed in fungi. They are known to be involved in the biosynthesis of ribosomally synthesized and posttranslationally modified peptides (RiPPs) and nonribosomal peptides, and possibly catalyze various reactions, including oxidative cyclization and chlorination. In this study, we focused on phomopsin A, a fungal RiPP consisting of unique nonproteinogenic amino acids. Gene knockout experiments demonstrated that three UstYa homologues, phomYc, phomYd, and phomYe, are essential for the desaturation of amino acid moieties, showing unprecedented function among UstYa family proteins. Sequence similarity network analysis indicated that their amino acid sequences are highly diverged and that most remain uncharacterized, paving the way for genome mining of fungal metabolites with unique modifications.

AbstractChiroptical nanomaterials have generated significant levels of interest for generating strong circularly polarized luminescence (CPL) signals. We used the Langmuir–Schaeffer technique to generate the continuous and compact assembly of CdSe/CdS chiral film. We assembled achiral CdSe/CdS nanorods by controlling the number of layers and angles between different layers. This allowed us to tailor chiroptical properties to achieve high CPL signals. The chiral film was symmetrical and had the highest circular dichroism (CD) response and CPL signals with ten layers (RH (right‐handed)‐/LH (left‐handed)‐5 + 5 layers) and a 45° inter‐angle. Specifically, RH‐5+5 of the chiral film exhibited 1431 mdeg of CD activity and strong CPL signals with a dissymmetry factor (glum) of 0.0997. The helical stacked crystal plates with linear birefringence resulted in strong circular birefringence, as determined by the Reusch model. Electromagnetic simulations indicated that such remarkable optical activity was attributed to the birefringence and dichroism of the well‐aligned CdSe/CdS nanorod layers in the chiral films. Under right/left circular polarized (RCP/LCP) light excitation, the well aligned semiconductor nanorods exhibited differences in the coupling efficiencies to RCP and LCP light. Our CdSe/CdS chiral films, which exhibit ultra‐strong CPL activity, will provide a novel strategy for the fabrication of chiroptical devices.

Published: October 2021

AbstractThe undesirable loss of methane (CH4) at remote locations welcomes approaches that ambiently functionalize CH4 on‐site without intense infrastructure investment. Recently, we found that electrochemical oxidation of vanadium(V)‐oxo with bisulfate ligand leads to CH4 activation at ambient conditions. The key question is whether such an observation is a one‐off coincidence or a general strategy for electrocatalyst design. Here, a general scheme of electrocatalytic CH4 activation with d0 early transition metals is established. The pre‐catalysts’ molecular structure, electrocatalytic kinetics, and mechanism were detailed for titanium (IV), vanadium (V), and chromium (VI) species as model systems. After a turnover‐limiting one‐electron electrochemical oxidation, the yielded ligand‐centered cation radicals activate CH4 with low activation energy and high selectivity. The reactivities are universal among early transition metals from Period 4 to 6, and the reactivities trend for different early transition metals correlate with their d orbital energies across periodic table. Our results offer new chemical insights towards developing advanced ambient electrocatalysts of natural gas.

AbstractCyanine dyes are exceptionally useful probes for a range of fluorescence‐based applications, but their photon output can be limited by trans‐to‐cis photoisomerization. We recently demonstrated that appending a ring system to the pentamethine cyanine ring system improves the quantum yield and extends the fluorescence lifetime. Here, we report an optimized synthesis of persulfonated variants that enable efficient labeling of nucleic acids and proteins. We demonstrate that a bifunctional sulfonated tertiary amide significantly improves the optical properties of the resulting bioconjugates. These new conformationally restricted cyanines are compared to the parent cyanine derivatives in a range of contexts. These include their use in the plasmonic hotspot of a DNA‐nanoantenna, in single‐molecule Förster‐resonance energy transfer (FRET) applications, far‐red fluorescence‐lifetime imaging microscopy (FLIM), and single‐molecule localization microscopy (SMLM). These efforts define contexts in which eliminating cyanine isomerization provides meaningful benefits to imaging performance.

Published: October 2021

AbstractMelamine‐formaldehyde (MF) foam has wide applications due to good flame retardancy, excellent sound absorption, and high thermal stability. However, the recycling of MF foam wastes remains a challenge due to its thermosetting nature. Here, we demonstrate a new strategy for discarded foams as solid adsorbents for removing tin ions in simulated tin‐containing wastewater. Results showed that the removal rate of tin in simulated wastewater is as high as 99.996%. Moreover, after simple calcination, as‐obtained products can be used as high‐efficiency flame retardants for flexible poly(vinyl chloride) (PVC), reducing the peak of heat release rate and total smoke production of PVC by 51.8% and 45.8%, respectively, under the condition of 2.5 wt.% addition. In short, this strategy successfully converted MF foam and tin wastewater to valuable flame retardants, opening the way for the environmentally friendly recycling of MF waste and the simultaneous treatment of tin‐containing wastewater.

Published: October 2021

We searched the US National Library of Medicine's PubMed, Google Scholar and the American Psychological Association's Psychinfo databases during September 2019 for citations and abstracts on abusive head trauma (AHT) and shaken baby syndrome prevention dated 1 January 2000 to 31 August 2019. We identified 53 empirical studies and performed a structured review to identify the effects of prevention, if any, on AHT. We identified three lines of investigation that have focused on: (i) strategies which teach parents how to respond to newborn crying and the dangers of shaking babies; (ii) community and public health factors; and (iii) professional education and practice. Most studies were observational, although a small number used sophisticated designs such as prospective or randomised controlled trials. We note other strengths and weaknesses of these articles and suggest future directions for research in each of these areas based on the current level of scientific inquiry.‘Identified 53 empirical studies and performed a structured review to identify the effects of prevention… on AHT’Key Practitioner Messages

Research on AHT prevention is limited, although a growing research base supports teaching parents how to respond to newborn crying and about the dangers of shaking babies.
Social care systems addressing provision of material and other support have positive effects on AHT rates.
Professional education should improve practitioners' identification of families with increased risk and enhance AHT identification and treatment.
Those wishing to prevent AHT should consider multilevel approaches and their own community needs, practice setting, and patient/client risk profiles when designing strategies.

Ultrathin Nickel‐doped ZnIn2S4 Nanosheets with Sulfur Vacancies for Efficient Photocatalytic Hydrogen Evolution
Authors: Liu Wangxi , Chen Jianmin , Pan Xueling , Wang Tingting , Li Yingwei 
Published: October 2021

AbstractIntroducing vacancies and element doping are effective approaches to boost photocatalytic activities of metal sulfides. In this work, sulfur vacancies and nickel dopants were simultaneously introduced into ultrathin ZnIn2S4 nanosheets (ZIS NSs) to explore their synergistic role in promoting photocatalytic hydrogen evolution. The S vacancies can trap the photo‐generated electrons, lower the conduction band minimum (CBM), improve the photo‐generated charge reduction capacity and prolong the carrier lifetime. Meanwhile, Ni dopants cause an increase in the Fermi level (EF), which ensures a higher charge density and an effective carrier separation efficiency. The optimum hydrogen evolution rate of sample Ni0.05−VS−ZIS reaches 8.91 mmol g−1 h−1 under visible light due to the synergistic effect of the S vacancies and Ni dopants.

Published: October 2021

AbstractThe specific chemical and physical evolutions of electrode materials under operating conditions should be understood to optimize their electrochemical performances. The in‐situ/operando techniques including Raman spectrum, transmission electron microscope, X‐ray diffraction, X‐ray absorption spectrum, and magnetization are powerful tools, which can provide the real‐time surficial/interfacial changes of electrodes, the transformation of crystal lattice structures, the adjustment of electronic states and even the influence of magnetic properties under operating conditions. In this Review, the advantages and limitations of these in‐situ/operando techniques in investigating the inner energy storage mechanisms of various type electrode materials are analyzed. The representative research results such as the ion dependent storage mechanism, step‐alloying processes and space charge storage theory are highlighted. In addition, the challenges and opportunities of in‐situ/operando characterizations are proposed as well.

AbstractAdequate immune response to vaccination remains a challenge in patients after solid organ transplantation. We report a case of a 61‐year‐old male patient who received a left ventricular assist device as a bridge to transplant therapy. Three months before transplantation, he suffered mild SARS‐CoV‐2 infection and was successfully discharged thereafter. Eight days before his successful heart transplantation, he received mRNA BNT 162b2 vaccination. Immediately after transplantation, we detected sufficient rise of nucleocapsid and spike antibodies despite immune suppression therapy. We suspect potential booster effects of the previous SARS‐CoV‐2 infection giving rise to adequate immune response following single vaccination.

Abstract
Pressures from anthropogenic activities are causing degradation of estuarine and coastal ecosystems around the world. Trace metals are key pollutants that are released and can partition in a range of environmental compartments, to be ultimately accumulated in exposed biota. The level of pressure varies with locations and the range and intensity of anthropogenic activities. The present study measured residues of trace metals in Mytilus mussel species collected from a range of locations around the world in areas experiencing a gradient of anthropogenic pressures that we classified as low, moderate, or high impact. The data showed no grouping/impact level when sampling sites in all countries were incorporated in the analysis, but there was significant clustering/impact level for most countries. Overall, high-impact areas were characterized by elevated concentrations of zinc, lead, nickel, and arsenic, whereas copper and silver were detected at higher concentrations in medium-impact areas. Finally, whereas most metals were found at lower concentrations in areas classified as low impact, cadmium was typically elevated in these areas. The present study provides a unique snapshot of worldwide levels of coastal metal contamination through the use of Mytilus species, a well-established marine biomonitoring tool.

Speculation or hedging?—Options trading prior to FOMC announcements
Authors: Jiang George J. , Pan Guanzhong 
Published: October 2021

AbstractThis paper investigates options trading activity before Federal Open Market Committee (FOMC) announcements. We find evidence that informed traders use options to speculate on their private information for the upcoming FOMC announcements. Specifically, abnormal trading volume of call options on S&P 500 index during the preannouncement window positively predicts postannouncement index returns, and this predictability mainly comes from near‐the‐money call options. Moreover, we further break down trading volume based on the direction of trades and show that buyer‐initiated call option trading volume positively predicts postannouncement index returns. We find no evidence that investors use options to hedge postannouncement market uncertainty.
