AbstractThe microbial priming effect—the decomposition of soil organic carbon (SOC) induced by plant inputs—has long been considered an important driver of SOC dynamics, yet we have limited understanding about the direction, intensity, and drivers of priming across ecosystem types and biomes. This gap hinders our ability to predict how shifts in litter inputs under global change can affect climate feedbacks. Here, we synthesized 18,919 observations of CO2 effluxes in 802 soils across the globe to test the relative effects (i.e., log response ratio [RR]) of litter additions on native SOC decomposition and identified the dominant environmental drivers in natural ecosystems and agricultural lands. Globally, litter additions enhanced native SOC decomposition (RR = 0.35, 95% CI: 0.32–0.38), with greater priming effects occurring with decreasing latitude and more in agricultural soils (RR = 0.43) than in uncultivated soils (RR = 0.28). In natural ecosystems, soil pH and microbial community composition (e.g., bacteria: fungi ratio) were the best predictors of priming, with greater effects occurring in acidic, bacteria‐dominated sandy soils. In contrast, the substrate properties of plant litter and soils were the most important drivers of priming in agricultural systems since soils with high C:N ratios and those receiving large inputs of low‐quality litter had the highest priming effects. Collectively, our results suggest that, though different factors may control priming effects, the ubiquitous nature of priming means that alterations of litter quality and quantity owing to global changes will likely have consequences for global C cycling and climate forcing.
Experimental warming reduces body mass but not reproductive investment
Authors: Lackey Alycia C. R. , Whiteman Howard H. 
Published: June 2022

AbstractClimate change has already had wide‐ranging effects on populations, including shifts in species' ranges, phenology, and body size. Whereas some common patterns have emerged, the direction and magnitude of responses vary extensively among populations as well as across life stages within populations. Understanding the consequences of climate change and predicting future responses at the population level require experimental tests of how warmer temperatures affect life history traits, including growth rate, development time, and reproductive output. Here, we tested how experimental warming affected life history from larval development and survival to adult reproductive maturity and investment in mole salamanders, Ambystoma talpoideum. We found that a small temperature increase (~1°C) experienced during larval development had complex consequences: density‐dependent effects on growth and body mass, density‐independent effects on fat storage, and no effects on survival and reproductive investment. Although warming reduced growth rates, size at maturity, and fat storage, salamanders in both warmed and control conditions had similar survival and reproductive investment in their first year. However, costs of smaller body size and lower fat reserves may limit overwintering survival and/or future reproduction. Our study highlights the differential effects of warming across life history traits and multifaceted population responses to climate change. This work motivates future studies to examine variation in response to climate change across life stages and life history traits.

AbstractThe efficient preparation of catalyst is an important topic for its industrial application. The Sn‐containing zeolite is one kind of important catalysts for many catalytic conversions of oxygenated chemicals. In this work, an efficient strategy for preparation of Sn‐MFI zeolite was developed, of which space‐time yield can reach 62.58 kg/m3⋅h, which is 120 times higher than that of typical hydrothermal route (0.53 kg/m3⋅h). Combining XRD, TEM, XPS, FT‐IR, 29Si NMR and other characterization methods, the framework tin sites were confirmed, and key role of ethylenediamine (EDA) for formation of which was revealed. Additionally, the framework tin sites content and catalytic activity of the Sn‐MFI prepared by this strategy is comparable to that of Sn‐MFI‐hy prepared by typical route in the conversion of dihydroxypropanone (DHA) to methyl lactate (ML), which gives ML yield of 80.64 % under optimized conditions. The proposed methodology can be extended to other types of Sn‐containing zeolite, which will certainly promote its industrial application.

Published: June 2022

AbstractThe reactivity of low‐valent alkyl‐substituted metallacyclobutadienes towards electron‐rich alkynes was studied. Treatment of the alkyl‐substituted rhenacyclobutadiene complexes Re{−C(R)=C(CO2Et)C(OEt)=}(CO)4 (R=Me, Et) with HC≡COEt produced a mixture of the cyclopentadienyl complexes Re{η5‐C5H(R)(CO2Et)(OEt)2}(CO)3 and the new rhenacyclobutadienes Re{−C(OEt)=C[C(R)=CH(CO2Et)]C(OEt)=}(CO)4 bearing a pendant vinyl substituent C(R)=CH(CO2Et) at the β‐carbon. The reactions proceed through initial nucleophilic attack of the terminal carbon of HC≡COEt on the ReC(R) carbon of the starting rhenacyclobutadienes. The rhenacyclobutadiene complex Re{−C(Me)=C(CO2Et)C(OEt)=}(CO)4 reacted with aminoalkynes RC≡CNEt2 (R=Ph, Me) to produce the unusual coupling products Re{−C(OEt)=C(CO2Et)C[CH=C(NEt2)CH2R]=}(CO)4, metallacyclobutadiene complexes bearing the vinyl substituent CH=C(NEt2)CH2R at an α‐carbon. The mechanisms of the reactions are discussed.

Published: June 2022

AbstractA vast variety of oxidation procedures is known to obtain 2,2,6,6‐tetramethylpiperidinyl‐4‐oxyl (TEMPO) moieties from its piperidinyl precursor. However, up to now no comprehensive study has been performed concerning the performance and feasibility for lab‐scale synthesis. With the focus on the ease of synthesis, occurring impurities, the reaction yield and the degree of oxidation (DoO), this study represents a thorough investigation of different oxidation processes yielding N‐oxyl radicals in a one‐step procedure. The resulting materials were investigated by redox titration and electron spin resonance spectroscopy to determine the DoO, which is the determining parameter for the yield of this oxidation reaction. The most promising procedures have been transferred to a polymeric material to evaluate the feasibility of the catalysts for more complex substrates.

Abstract2‐Nitroglycal is a widely used synthon for aminoglycosides synthesis. Herein, we report an efficient method for 2‐nitroglycals synthesis using nBu4NNO3/Tf2O/DTBMP. Using 3‐O‐acetyl‐2‐nitroglycals as donors, a novel method for the construction of challenging 1,2‐cis‐2,3‐diamino‐2,3‐dideoxyglycosidic linkages was established using 4‐pyrrolidinopyridine (PPY) mediated relay glycosylation reaction. The method enjoys many features, including very mild reaction condition, excellent regio‐ and stereoselectivity, good to excellent yields and broad substrate scope.

AbstractNew results, as reported in a forthcoming paper (Cacciari & Ranfagni, 2022), induced us to modify our point of view on the origin of the transfer of modulation between microwave beams. We believe that a commentary and addition of information to the paper published as Reference 1 appear appropriate.

Published: June 2022

AbstractIn this paper, a Random‐XFEM technology was employed to simulate hydraulic fracture interaction with the natural void in a random field of Young's modulus. The random distribution of Young's modulus is characterized by random field theory, while the stress and pressure fields fracturing were solved by the extended finite element method. And a Random‐XFEM iteration algorithm was proposed to solve the hydraulic fracture propagation problem. Then the proposed model was verified against the KGD model and numerical study. A series of numerical examples were presented to analyze the interaction mechanism of hydraulic fracture and void in a random field. The numerical results show that the random field of Young's modulus has a great impact on the hydraulic fracture propagation path. Under the random distribution of Young's modulus, the hydraulic fracture would deviate from the direction of maximum horizontal principal stress. And the random field parameters (Young's modulus mean and point variance) have different effects on the hydraulic fracture propagation path. Also, the interaction patterns of hydraulic fracture and void are greatly affected by random fields.

Published: June 2022

AbstractSolid‐state thermoelectric (TE) devices offer many interesting features compared with other methods of generation, such as no moving parts, high reliability, low maintenance, and straightforward integration with other heating equipment. In this study, a thermoelectric assembly was integrated into a residential heating boiler to convert a portion of combustion heat to electricity while meeting space and/or water heating needs. A prototype was developed, in which recently developed thermoelectric modules were incorporated into a gas‐fired boiler. The electricity generated by the thermoelectric assembly would be sufficient to power the electrical auxiliary components of the heating system. In this way, the heating system could operate entirely on fuel combustion and provide the consumer with heating system reliability and a reduction in power consumption. A model for the thermoelectric conversion system was established and the thermal resistance analysis was carried out to show the influence of heat transfer coefficients and other parameters on power output and efficiency, and thus improve the system design. In this study, the single‐module integrated assembly can produce a 22.5 W power output. However, each module of the four‐/eight‐module integrated assembly can only generate a power output of 7.85/9.175 W on average. The performance of a single module in a multimodule assembly is worse than that of a single module assembly. The number of modules placed on the furnace wall is not as many as possible but has an optimal value. In this experimental environment, the assembly of eight modules is the optimal choice. Furthermore, it is found that enhancing combustion‐side heat transfer capacity is an effective way to promote system performance. The power output of the assembly composed of four modules will increase by 70% from 7.85 to 13.5 W due to the installation of the fin on the hot end.

Published: June 2022

Abstract
Most regulatory ecological risk-assessment frameworks largely disregard discrepancies between the laboratory, where effects of single substances are assessed on individual organisms, and the real environment, where organisms live together in populations and are often exposed to multiple simultaneously occurring substances. We assessed the capability of individual-based models (IBMs) with a foundation in the dynamic energy budget (DEB) theory to predict combined effects of chemical mixtures on populations when they are calibrated on toxicity data of single substances at the individual level only. We calibrated a DEB-IBM for Daphnia magna for four compounds (pyrene, dicofol, α-hexachlorocyclohexane, and endosulfan), covering different physiological modes of action. We then performed a 17-week population experiment with D. magna (designed using the DEB-IBM), in which we tested mixture combinations of these chemicals at relevant concentrations, in a constant exposure phase (7-week exposure and recovery), followed by a pulsed exposure phase (3-day pulse exposure and recovery). The DEB-IBM was validated by comparing blind predictions of mixture toxicity effects with the population data. The DEB-IBM accurately predicted mixture toxicity effects on population abundance in both phases when assuming independent action at the effect mechanism level. The population recovery after the constant exposure was well predicted, but recovery after the pulse was not. The latter could be related to insufficient consideration of stochasticity in experimental design, model implementation, or both. Importantly, the mechanistic DEB-IBM performed better than conventional statistical mixture assessment methods. We conclude that the DEB-IBM, calibrated using only single-substance individual-level toxicity data, produces accurate predictions of population-level mixture effects and can therefore provide meaningful contributions to ecological risk assessment of environmentally realistic mixture exposure scenarios.

Published: June 2022

Abstract
Bisphenol AF (BPAF) is a structural counterpart of bisphenol A that is utilized in the food and beverage industry. The present study investigated the potential mechanisms in BPAF-induced neurotoxicity in zebrafish embryos. The BPAF concentrations (0.03, 0.1, 0.3, and 1.0 µM) had no obvious effect on hatching, mortality, and body length of zebrafish larvae, while curved tail and pericardial edema were observed in the 1.0 μM group at 72 and 96 h postfertilization (hpf). Locomotor activity of the larvae (at 120 hpf) significantly decreased from dark to light but increased from light to dark transitions in BPAF groups (0.1, 0.3, and 1.0 μM). Acridine orange showed that BPAF significantly increased green fluorescence protein intensity (22.6%) in the 1.0 μM group. Consistently, the induced apoptosis significantly up-regulated caspase 3 at 0.3 μM (1.95-fold) and 1.0 μM (2.26-fold) and bax at 0.3 μM (1.60-fold) and 1.0 μM (1.78-fold), whereas bcl-2 expression was significantly decreased at 0.3 μM (0.72-fold) and 1.0 μM (0.53-fold). In addition, increased reactive oxygen species concentrations at 0.3 μM (27%) and 1.0 μM (61.4%) resulted in suppressed superoxide dismutase and catalase activities. Moreover, quantitative polymerase chain reaction results showed that BPAF (0.3 and 1.0 μM) significantly altered normal dopaminergic signaling where dat was up-regulated, while drd2a and th1 were down-regulated, in a concentration-dependent manner. Aberrations in dopamine-related genes were congruous with the dysregulations in neurodevelopment genes (sox11b, pax6a, syn2a, and rob2). Our findings suggest that BPAF-evoked oxidative stress and apoptosis could translate into phenotypical behavioral and neurodevelopmental abnormalities. These highlights could provide theoretical reference for risk assessment and act as an early indicator to BPAF exposure. Environ Toxicol Chem 2022;41:2273–2284. © 2022 SETAC

AbstractHuangjiu, a traditional Chinese wine with low alcoholic strength, can easily develop rancidification upon microbial contamination in the long‐term storage process. In order to analyze the changes in key indexes in the rancidification process during the storage of Huangjiu, a laboratory simulation of microbial contamination changes was carried out. Changes in microbiological indexes, physicochemical indexes, and volatile flavor compounds in the rancidification process of Huangjiu can be divided into two stages. Test results demonstrated that within the early stage of the rancidification process, multiplication of contaminating microorganisms was in the adaptation phase with a slow OD600 growth value of Huangjiu, while physicochemical indexes such as the pH and amino acid nitrogen content changed relatively slowly. The contents of aldehyde compounds in the volatile flavor components of Huangjiu declined quickly to be lower than 1.0 mg/L, while the conductivity index increased by 6%. In the late stage, the OD600 value of Huangjiu increased rapidly and microorganism multiplication entered the logarithmic phase. Furthermore, changes in the physicochemical indexes are accelerated. Specifically, the histamine content increased by 457% and the content of aldehydes remains lower than 1.0 mg/L. The conductivity index continued to rise by 25% in this stage. This indicates that the two rancidification stages have different influences on the quality of Huangjiu. The conductivity value can be used as a staged representative index throughout the rancidification of Huangjiu to distinguish between different batches and evaluate the degree of microbial contamination. Additionally, the conductivity index can be used for long‐term online monitoring of large tank storage of Huangjiu.
RETRACTED: Applying geoarchaeological principles to marine archaeology: A reappraisal of the “first marine” and “in situ” lithic scatters in the Dampier Archipelago, NW Australia
Authors: Ward Ingrid , Larcombe Piers , Ross Peter J. , Fandry Chris 
Published: June 2022

AbstractThe absence of known prehistoric underwater cultural heritage (UCH) sites on the Australian inner shelf stands in stark contrast to the thousands of sites revealed elsewhere in the world. Two recent claims—Dortch et al. (D2019) and Benjamin et al. (B2020)—put forward the first in situ (i.e., primary context) UCH sites in the shallow waters of the Dampier Archipelago, North West Australia, each arguing that the stone artefact scatters are at least 7000 years old and are now submerged because of postglacial sea‐level rise. We present new hydrodynamic modelling and data on coastal erosion and bathymetry, and reassess each site's sedimentary setting and archaeological site‐formation history. D2019 and B2020 clearly present lithic cultural artefacts, but the arguments for their sites being of primary context and reflecting early Holocene land surfaces are mistaken. Rather, these sites occur in the intertidal zone, and many or all artefacts are likely to have been reworked. Sites of secondary context, if treated appropriately, can inform our understanding of site‐formation process and change, and may support more powerful contributions to submerged archaeology than attempts to seek the first or the oldest.

AbstractIssues addressedUrgent action is required by all levels of government to create a food system capable of nourishing a rapidly growing population while remaining within planetary boundaries. This study investigated policies and programs implemented by Australian local governments (LGs) that aim to contribute to a healthy, sustainable and equitable food system.MethodsAn online survey was completed by LGs (n = 64) in New South Wales and Victoria, Australia. Questions focused on LGs' food system‐related policies and programs, barriers to and enablers of engaging in food system work and organisational responsibilities for food system work.ResultsPreventing food waste, organising food‐related social/cultural events and providing potable water were the most commonly reported activities. Few LGs reported policies/activities on market gardening or sustainable agricultural practices, or strengthening food system resilience. LGs implemented a wide range of initiatives, such as hosting food forums, using research to identify and address food access issues and providing healthy food and drink options within LG‐owned/managed facilities. Enablers of food system work included internal LG support, human resources, external funding and partnerships. Barriers included lack of community interest, short‐term and/or project‐based funding, internal governance issues and restrictive state government planning frameworks.ConclusionAustralian LGs undertake a wide range of actions addressing diverse food system issues; however, internal and external barriers constrain their involvement in creating a healthy, sustainable and equitable food system.So what?Legislative reform, combined with increased financial and human resource capacity, would support LGs to expand, strengthen and sustain their food system work.
A review of regulatory modeling frameworks supporting numeric water quality criteria development in the United States
Authors: Barnhart Brad , Flinders Camille 
Published: June 2022

Abstract
The US Environmental Protection Agency (USEPA) has a long history of leveraging environmental models and integrated modeling frameworks to support the regulatory development of numeric ambient water quality criteria for the protection of aquatic life and human health. Primary modeling types include conceptual, mechanistic, and data-driven empirical models; Bayesian and probabilistic models; and risk-based modeling frameworks. These models and modeling frameworks differ in their applicability to and suitability for various water quality criteria objectives. They require varying knowledge of system processes and stressor-response relationships, data availability, and expertise of stakeholders. In addition, models can be distinguished by their ability to characterize variability and uncertainty. In this work, we review USEPA recommendations for model use in existing regulatory frameworks, technical support documents, and peer-reviewed literature. We characterize key attributes, identify knowledge gaps and opportunities for future research, and highlight where renewed USEPA guidance is needed to promote the development and use of models in numeric criteria derivation. These outcomes then inform a decision-based framework for determining model suitability under particular scenarios of available knowledge, data, and access to technical resources.
