AbstractExploring cost‐efficient/durability bifunctional electrocatalysts are of upmost importance for the practical application of metal–air batteries. However, preparing bifunctional electrocatalysts with the above three advantages remains conceptually challenging. This work reports the preparation of N‐doped carbon confined NiCo alloy hollow spheres (NiCo@N−C HS) as bifunctional oxygen electrocatalyst for Zn‐air battery with a higher energy density (788.7 mWh gZn−1) and outstanding cycling stability (over 200 h), which are more durable than the commercialized Pt/C+RuO2‐based device. Electrochemical results and theoretical calculation demonstrate that the synergy in the NiCo@N−C accelerates the electronic transmission for improving activation of O2* and OH* intermediates and optimizing reacted free energy pathways, while the hollow structures exposure more active sites for improving the reaction kinetics and enhancing the activity of ORR/OER reaction. This work provides crucial understanding for constructing low‐cost transition metal‐based catalyst to overcome the efficiency and durability barriers of metal‐air batteries for widespread applications.
Mammalian D‐Cysteine: A new addition to the growing family of biologically relevant D‐amino acids
Authors: Roychaudhuri Robin 
Published: March 2023

AbstractMammalian D‐Cysteine is racemized from L‐cysteine by serine racemase, a pyridoxal phosphate (PLP)‐dependent enzyme. Endogenous D‐Cysteine plays a role in neural development by inhibiting proliferation of neural progenitor cells (NPCs) via protein kinase B (AKT) signaling mediated by the FoxO family of transcription factors. D‐Cysteine binds to Myristoylated Alanine Rich C Kinase Substrate (MARCKS) and alters phosphorylation at Ser 159/163 and its translocation from the membrane. By racemizing serine and cysteine, mammalian serine racemase may play important roles in neural development highlighting its importance in psychiatric disorders.

AbstractBackgroundAcute myeloid leukemia (AML) with rearrangement of lysine methyltransferase 2a gene (KMT2Ar) is characterized by chemotherapy resistance and high rates of relapse. However, additional causes of treatment failure or early mortality have not been well‐defined in this entity.MethodsIn a retrospective analysis, causes and rates of early mortality following induction treatment were compared between a cohort of adults with KMT2Ar AML (N = 172) and an age‐matched cohort of patients with normal karyotype AML (N = 522).ResultsThe 60‐day mortality in patients with KMT2Ar AML was 15% compared with 7% with normal karyotype (p = .04). We found a significantly higher occurrence of major bleeding events (p = .005) and total bleeding events (p = .001) in KMT2Ar AML compared with diploid AML. Among evaluable patients with KMT2Ar AML, 93% exhibited overt disseminated intravascular coagulopathy compared with 54% of patients with a normal karyotype before death (p = .03). In a multivariate analysis, KMT2Ar and a monocytic phenotypic were the only independent predictors of any bleeding event in patients who died within 60 days (odds ratio, 3.5; 95% CI, 1.4–10.4; p = .03; odds ratio, 3.2; 95% CI, 1–1‐9.4; p = .04, respectively).ConclusionIn conclusion, early recognition and aggressive management of disseminated intravascular coagulopathy and coagulopathy are important considerations that could mitigate the risk of death during induction treatment in KMT2Ar AML.Plain Language Summary

Acute myeloid leukemia (AML) with rearrangement of KMT2A is characterized by chemotherapy resistance and high rates of relapse. However, additional causes of treatment failure or early mortality have not been well‐defined in this entity.

In this article, that KMT2A‐rearranged AML is demonstrably associated with higher early mortality and an increased risk of bleeding and coagulopathy, specifically, disseminated intravascular coagulation, compared with normal karyotype AML.

These findings emphasize the importance of monitoring and mitigating coagulopathy in KMT2A‐rearranged leukemia similar to what is done in acute promyelocytic leukemia.

AbstractDeveloping an understanding of the interactions between an antibiotic and its binding site in a pathogen cell is the key to antibiotic design—an important cost‐saving methodology compared to the costly and time‐consuming random trial‐and‐error approach. The rapid development of antibiotic resistance provides an impetus for such studies. Recent years have witnessed the beginning of the use of combined computational techniques, including computer simulations and quantum mechanical computations, to understand how antibiotics bind at the active site of aminoacyl tRNA synthetases (aaRSs) from pathogens. Such computational protocols assist the knowledge‐based design of antibiotics targeting aaRSs, which are their validated targets. After the ideas behind the protocols and their strategic planning are discussed, the protocols are described along with their major outcomes. This is followed by an integration of results from the different basic protocols. © 2023 Wiley Periodicals LLC.Basic Protocol 1: Analysis of active‐site residues from primary sequence of synthetase and transfer RNAsBasic Protocol 2: Molecular dynamics simulation‐based protocol to study the structure and dynamics of the aaRS active site:antibiotic complexBasic Protocol 3: Quantum mechanical method‐based protocol to study the structure and dynamics of the aaRS active site:antibiotic complex

AbstractCotton (Gossypium hirsutumL.) is not only the dominant fiber crop grown worldwide, but it is also an important source of plant‐based oil and protein. Previous research has documented a significant effect of cotton cultivar and nitrogen application individually on lint yield and seed composition, but very limited studies have evaluated the lint, seed, oil, and protein yield responses of cultivars with different seed mass and composition to a broad range of N application rates. The objective of this study was to evaluate the lint, seed, oil, and protein yield responses of cultivars with different seed mass and composition to N application rates (0–168 kg N ha−1) for field‐grown cotton. A field experiment was conducted in Tifton, GA, USA during the 2019 and 2020 growing seasons that included six cultivars and six N application rates. Cultivar significantly affected seedcotton, lint, seed, and seed reserve yields in both growing seasons. Lint yield did not follow identical trends as seed yield mainly due to cultivar variation in lint percent. Similarly, protein and oil yield were influenced by cultivar variation in seed composition. Seedcotton, seed, protein, and oil yields continually increased with increases in N application from 0 to 168 kg N ha−1, whereas for lint yield, all fertilized treatments produced comparable yields that were significantly higher (68%) than the 0 kg N ha−1treatment. We conclude that variability in the distribution of photosynthates to fiber and seed as well as seed oil and protein composition can significantly alter trends in fiber, seed, and seed component yields in response to cultivar or N application rates for field‐grown cotton.

SummaryIn wireless sensor networks (WSNs), the data must reach a processing node with less energy consumption and delay rate. However, with the specific consideration of the unique properties of sensor networks such as limited power, stringent bandwidth, dynamic topology due to node failures, adding/removing nodes, or even physical mobility, high network density and large‐scale deployments have posed many challenges in the design and management of sensor networks. These challenges have demanded energy awareness and robust protocol design. Efficient utilization of the sensor's energy resources and maximizing the network lifetime were the primary design considerations for the proposed work. As a result, the new interior gateway routing with particle swarm optimization (IGRPSO) is presented with minimal latency and a higher packet delivery ratio in WSN; optimum link weights are calculated in a fraction of the original data to the new protocol. Network entropy maximization is a conceptual framework that guides the development of the protocol and the computational techniques required to determine which traffic distributions are not only best but also realizable through link‐state routing. Therefore, a routing algorithm provides the optimal and economically optimal route. We used the MATLAB simulation environment to compare and contrast the performance of the dynamic source routing (DSR) protocol and enhanced interior gateway routing protocol, DSR protocol with particle swarm optimization with that of the IGRPSO protocol, which has the maximum packet delivery ratio of 75.74% and less packet drop of 25.37%, less energy consumption of 0.3674 J.

AbstractBackgroundClinical interventions aim to improve the daily life experiences of patients. However, past research has highlighted important discrepancies between commonly used assessments (e.g. retrospective questionnaires) and patients' daily life experiences of pain. These gaps may contribute to flawed clinical decision‐making and ineffective care. Recent work suggests that real‐time, task‐based clinical assessments may help reduce these discrepancies by adding predictive value in explaining daily life pain experiences. This study aimed to investigate these relationships by evaluating whether task‐based measures of sensitivity to physical activity (SPA) predict daily life pain and mood, beyond traditional pain‐related questionnaires.MethodsAdults with back pain (<6‐month onset) answered pain‐related questionnaires and completed a standardized lifting task. SPA‐Pain, SPA‐Sensory and SPA‐Mood were, respectively, assessed as task‐evoked changes in pain intensity, pressure pain threshold (back, hands), situational catastrophizing. Over the next 9 days, daily life pain and mood were assessed using smartphone‐based ecological momentary assessment (EMA‐Pain and EMA‐Mood, respectively) with stratified random sampling. Data analyses estimated fixed effects (b) using multilevel linear modelling with random intercepts.ResultsMedian EMA completion per participant was 66.67% (n = 67 participants). After controlling for covariates, SPA‐Pain was associated with EMA‐Pain (b = 0.235, p = 0.002) and SPA‐Psych approached significance with EMA‐Mood (b = −0.159, p = 0.052).ConclusionsTask‐based assessment of SPA helps explain daily life pain and mood among adults with back pain, beyond traditional questionnaires. Adding task‐based assessment of SPA may achieve a more complete picture of pain and mood in daily life, offering clinicians better guidance when prescribing activity‐based interventions that are designed to modify daily life behaviour, such as graded activity.SignificanceThis study found that, among people with back pain, task‐based measures of sensitivity to physical activity contribute additional predictive value for daily life pain and mood beyond self‐report questionnaires. Findings suggest that real‐time, task‐based measures may help mitigate some of the shortcomings that are commonly associated with retrospective questionnaires.

Published: March 2023

AbstractIn this work, supercapacitor or ultra‐capacitor cells are composed of active carbon material (ACM) having BET specific surface area of 1133 m2 g−1. The ACM is prepared by carbonizing waste biomass (mango kernel) at 900°C. To develop high porosity in ACM, potassium hydroxide was used as an activating agent. Porous morphology of the synthesized ACM is explored through Scanning Electron Microcopy. Thereafter, two supercapacitor cells have been composed by using the mentioned ACM (electrode material) and KOH 6 M & NaOH 1 M (electrolytes). Applicability of the electrode material for supercapacitor has been tested electrochemically through the standard CV, EIS, and CD techniques. Observed capacitive assets from CV curve at 5 mV s−1was 151.5 F g−1(with KOH 6 M) and 133 F g−1(with NaOH 1 M). Experimentally obtained impedance data from EIS technique were compared and fitted theoretically by utilizing Randles fitting circuit. By taking frequency into consideration, it is found that the KOH 6 M based cell is providing lower time constant value and supporting better diffusion process than NaOH. Analysis of CD curve at 1.1 A g−1have given the capacitance of 136.5 F g−1and corresponding energy and power density of 12.1 Wh kg−1and 930 W kg−1. In addition to this, the small voltage drop and low ohmic resistance observed with KOH based system suggests its better capacitive assets than NaOH based supercapacitor system. Moreover, good capacitance retention of 85% is observed in a 2000 life cycle test.
Simultaneous effects of viscous and Darcy dissipation on mixed convection flow in an annulus partially filled with porous material: Analytical approach

Published: March 2023

AbstractThe effect of thermal dissipation on a steady, fully developed, mixed convection viscous, incompressible fluid in an annulus partially filled with porous materials has been thoroughly examined in this work. Fluid flow begins within the annulus when a pressure gradient is applied abruptly in the flow direction. The fluid flow in the porous zone is characterized by the Brinkmann‐extended Darcy model. The fluid is divided into transparent and porous parts by a minimal interface. By matching their velocities and considering the shear stress jump conditions at the interface, the clear fluid and the porous region are connected. Additionally, the viscous dissipation effect is considered while determining the energy equation in the clear fluid zone. However, in the porous area, the Darcy dissipation effects are considered in addition to the viscous dissipation influence. In the model, the results of various fluid parameters in the problem were addressed using line graphs and the homotopy perturbation method. The study found that when the porous region's thickness grows, heat transmission on the annular surface enclosing the clear fluid region increases while it decreases on the border surface close to the porous region. In addition, a thicker porous region requires a greater pressure gradient to propel the flow.

AbstractUnderstanding the spatiotemporal nitrate retention in streambed is essential for developing management practices in reducing nitrate enrichment. However，the process of nitrate change in the profile of streambed at an elevated nitrate across a watershed scale is still not sufficiently investigated. In this study, we used a combination of hydraulic and hydro‐geochemistry methods to quantify total nitrate retention in streambeds of an agriculture‐intensive watershed in Central China. To conduct surface and groundwater measurements, we collected 1440 water samples for nitrate analysis from 40 shallow drilled wells during the dry and wet seasons from 2018 to 2020. The results showed a clear spatiotemporal variation of nitrate retention in streambed in the watershed. Spatially, nitrate retention in the midstream and downstream reaches was higher than that of the upstream reach. The lowest point of nitrate retention in downstream both in dry and wet seasons was at the depth of 0.75 m. While the lowest nitrate retention was found in midstream and upstream reaches, both in the dry and wet seasons at the depth between 1.5 and 2.5 m. Temporally, nitrate retention was higher in the wet season (1.56 μg N m−2d−1) than in dry season (1.41 μg N m−2d−1). DO min at 3 mg/L was found to the nitrate retention zero threshold in up and midstream. Water change fluxes and nitrate retention both have positive and negative relationship at watershed scale. Nitrate retention at the watershed scale was strongly affected by streambed lithology, precipitation, surface water ‐ groundwater exchange, and human activities. Those findings can provide reference for nitrate removal in international important agricultural areas.

AbstractBACKGROUNDThe difficulty of separating fiber from polyolefin coatings of single‐use plastic (SUP) cups for cold (carbonated) or hot (coffee) drinks, has led us to investigate a recycling method to obtain new high‐performance materials. The present work relates to valorization of ICEE S.A. de C.V. cups into crystalline nanocellulose (CNC), while studying the effects on the structural, thermal, morphological and particle size properties in dependence of the acid hydrolysis concentration (40 and 64% v/v) employing sulfuric acid to remove amorphous cellulose.RESULTSOn the basis of results, optimal CNC was found at 64% v/v concentration obtaining ribbon‐like morphologies rich in cellulose types Iα (27%) and II (45.1%) of triclinic and monoclinic structures, respectively, high crystallinity percentage (91%) and nanosize scale (26.70 nm). CNC was successfully grafted through the C2 in cellulose onto the methyl methacrylate (MMA) monomer to obtain PMMA‐g‐CNC, considering different concentrations (5, 10, 20 and 30 wt%) of CNC. A reduction of crystallinity % was found when CNC is grafted onto MMA owing to the amorphous nature of the poly(methyl methacrylate) (PMMA). However, this is not a limitation.CONCLUSIONSPMMA‐g‐CNC samples displayed high thermal stability (345 °C) and nanometric scale (165–260 nm), which have potential to be studied as reinforcement agents for incompatible polymers such as PMMA and poly(urethane) (PU) through Interpenetrating Polymer Networks. Preliminary mechanical studies indicated that PMMA‐g‐CNC systems are able to reinforce the tensile properties becoming the PMMA/PU into ductile materials. Specially, the MMA90CNC10 system improved the strain four‐fold compared to the pure PMMA/PU IPN. © 2023 Society of Chemical Industry (SCI).

Published: March 2023

AbstractTunable broadband terahertz (THz) sources with power at the gigawatt level are desirable for many applications. A scheme to generate such THz emission by off‐axially injecting a weakly relativistic ultrashort laser into a parabolic plasma channel is presented. By utilizing two‐dimensional particle‐in‐cell simulation, it is demonstrated that there are two major physical mechanisms involved, i.e., linear mode conversion from laser wakefields and the electromagnetic waveguide mode excitation inside the plasma channel. The two radiation modes can lead to linearly polarized and radially polarized THz emissions, respectively, with distinct frequency spectra and spatial distributions. It is found that they predominate alternatively with the change of the plasma channel length. For a given plasma channel, one can switch the radiation modes by adjusting the injection position and the injection angle of the laser pulse. In particular, the radiation mode of the linear mode conversion can produce THz pulses with the peak amplitude of sub‐GV cm−1 with the energy conversion efficiency ≈10−3, even though the peak power of the incident laser is just at the terawatt level. The scheme provides a powerful THz source with tunable intensity, spatial distributions, spectra, and polarizations by simply adjusting the injection conditions of incident laser pulses.

AbstractSecret sharing, as a sophisticated cryptographic technique, is widely used to protect important messages in the information era. As an important evaluation criterion, being able to provide timely warning and judge the security of the secret once eavesdropping occurs is a highly practical way to minimize losses. Here, the concept of countersurveillance holographic secret sharing based on laser‐induced irreversible hologram reconfiguration of graphene oxides (GO) is demonstrated. The laser‐ and thermal diffusion‐induced reduced graphene oxides (rGO) form two regions with different transmittances, which are defined as rGO superpixels. The rGO superpixels enable synchronous two‐amplitude‐state modulation of the holographic pixels, resulting in hologram reconfiguration. As such, multisecret sharing is realized by introducing a deep‐learning gradient descent algorithm into hologram encoding, which broadens the functionality and information capacity. The results establish a high‐security information delivery platform based on GO and pave the way for an all‐optical on‐chip holographic cryptography strategy.
