Published: August 2021

AbstractSeparating distinct nanoparticles from a cluster by applying simple nonstructured light can be a novel approach for future industrial development. Understanding the type of distinct particles from a three‐particle cluster (i.e., chiral, plasmonic, and dielectric) based on different near‐field optical forces has not been reported so far. In most of the set ups, optical sorting is reported for radius‐based sorting of Mie‐ranged single object. Here, three different optical setups are proposed, illuminated by a linearly polarized plane wave (propagating along angle) in a particle cluster constructed with chiral, plasmonic, and dielectric nanoparticles in an air medium (case 1), half immersed in water (case 2), and fully immersed in water (case 3). All of those have supported the near‐field optical sorting from the cluster of three Rayleigh sized particles. It is observed that the dielectric object experiences counter‐intuitive optical pulling force mainly due to the effect of induced magnetic‐type resonance created on nearby plasmonic object. In contrast, plasmonic objects experience optical pushing force due to the transferred momentum of photon and chiral objects experience lateral force mainly due to the induced magnetic dipole on the chiral object.

Published: August 2021

AbstractThe dopaminergic system has been suggested to serve as a functional target for ketamine, especially with its addictive and antidepressant effects. In this work, intracellular vesicle impact electrochemical cytometry and single cell amperometry were applied to a model cell line to show that the intravesicular contents and number of exocytotic events increased and the fraction of release decreased after treatment by subanesthetic ketamine (1 μM for 15 min). In addition, time‐of‐flight secondary ion mass spectrometry was used to show that cellular lipids change following acute ketamine administration relative to control cells with an increased proportion of low‐curvature lipids and a decreased proportion of high‐curvature lipids. We propose that ketamine modulates dopaminergic function with a dose‐dependent pharmacologic action by dominantly interacting with different proteins and changing lipid composition. It might be helpful to better understand the relationship of the dopaminergic system and drug abuse, as well as anesthetic and antidepressant effects.

Published: August 2021

AbstractIn recent years, the continuous and uncontrollable presence of drug contaminants and their destructive effects on the environment has been raised as an environmental problem. A large proportion of drug contaminants are related to sedatives. Paracetamol is one of the most widely used sedatives in the world. In this study, the photocatalytic degradation of paracetamol under visible light in the presence of poly(glycidylmethacrylate)@polyaniline/CuO nanocomposite as a photocatalyst was investigated. This prepared nanocomposite was characterized by different techniques such as Fourier transform infrared (FT‐IR), scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy (EDX), thermogravimetric analysis (TGA), X‐ray diffraction (XRD), and transmission electron microscopy (TEM). The effect of various parameters such as the amount of photocatalyst, irradiation time, temperature, and pH of the solution was studied on drug degradation. The degradation of paracetamol (PA) was assessed by adding a number of radical scavengers to the solution. More than 99% of paracetamol (10 mg L−1) was degraded under operating conditions in 90 min.

Published: August 2021

AbstractA novel SA‐f‐MWCNTs/PAN composite membrane, sodium alginate‐ functionalized multi‐walled carbon nanotubes/polyacrylonitrile, was prepared to enhance the esterification conversion rate with a pervaporation membrane reactor. The SA‐f‐MWCNTs/PAN membrane was investigated by Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and scanning electron microscope. The hydrophilicity, mechanical properties, and separation performance of the composite membrane have been significantly improved. The flux of the composite membrane was 4374 g·m−2·h−1, and the separation factor was 1249 (the water content in the feed was 10 wt%, at 75°C). The composite membrane the trade‐off effect between flux and separation factor. The acid conversion rate of SA‐f‐MWCNTs/PAN membrane was up to 98.3% in 5 h at 75°C, which was a great increase of 18.3% compared with the equilibrium conversion rate of the batch reactor. In addition, SA‐f‐MWCNTs/PAN membrane exhibited good swelling resistance and reusability. The conversion rate of acetic acid was stable above 95.0% after 8 repetitive tests.

Published: August 2021

AbstractLithium sulfur batteries (LSBs) have been seen as of considerable potential candidate for lithium‐ion batteries (LIBs) to satisfy high energy density demand. However, the application of LSBs until now has been stubbornly dragged by the “shuttle effect” of lithium polysulfides (LiPSs) due to dissolution of LiPSs in electrolyte and reaction with the lithium anode, incurring a severe capacity decay. Herein, the straightforward separator modification method that multiphase and multicomponent nickel‐iron oxide heterostructure grown on oxidized carbon nanotube (NiFe2O4−NiO/OCNT) composites directly coated on the polypropylene (PP) separator, has been implemented, which effectively inhibits the migration of LiPSs, enhances the electron and lithium‐ion transfer, and promotes the redox kinetics by virtue of the heterostructure interfaces between NiFe2O4, NiO, and OCNT. In conclusion, the synthesized NiFe2O4−NiO/OCNT/PP separator delivers good rate capacities and high stability up to 1000 cycles at 2 C with a low‐capacity decay rate of approximately 0.065 % per cycle.

Published: August 2021

The mental health problems of parents can negatively affect their whole family. The organisational and wider context may also influence the outcomes for all involved. The aims of this systematic review were: to develop a working definition of family‐focused practice (FFP); identify the types of outcomes that are measured with a focus on service user experiences; and explore how well interventions in the included studies fit with previously established components of FFP. A comprehensive literature search of 16 databases was conducted for peer‐reviewed, primary research studies related to FFP published between 1998 and 2016. In total, 3731 articles were identified and screened by four reviewers. Of those, 40 articles met all of the inclusion criteria. The review focused on family outcomes and, consistent with previous reviews, there was a reasonable degree of consistency about the core components of FFP. An additional component, identified by this review, which was part of some interventions, was work to improve access to and engagement with community supports and services. The review concludes that there is a need for: an agreed definition of FFP; clearer links to relevant theories; a more consistent approach to measuring outcomes, including economic perspectives; and an increased strategic promotion of whole family approaches.Key Practitioner Messages

Supported Vanadium Catalysts for Selective Sulfur‐Oxidative Dehydrogenation of Propane
Authors: Arinaga Allison M. , Alayoglu Selim , Zheng Ding , Marks Tobin J. 
Published: August 2021

AbstractThe catalytic oxidative dehydrogenation of propane (ODHP) is a challenging reaction due to facile competing overoxidation to COx. The gaseous disulfur molecule, S2, is isoelectronic with O2 and has been shown to act as an alternative, “soft oxidant” for the analogous process (SODHP) over bulk metal sulfide catalysts. However, these bulk catalysts suffer from low surface areas and ill‐defined active sites – issues that might be addressed with a supported catalyst. Here we investigate supported V/Al2O3 materials for SODHP. We show that these catalysts are highly selective for propylene, far surpassing the yields of the prior bulk systems. Isolated sulfided vanadium species are found to be more active and selective than crystalline vanadium sulfide. Additionally, we compare the S2 and O2 oxidants over sulfided and calcined V/Al2O3 materials, respectively, and find that the propylene selectivity is enhanced using S2 as the oxidant. These results suggest that sulfur is a promising soft oxidant that can be used to achieve high propylene selectivities over supported metal sulfides.

Published: August 2021

AbstractA wider use of the regional bioenergy resources for the development of environmentally friendly energy production providing microwave pretreatment of lignocellulosic biomass pellets (wood, straw, and peat) of different origin at a frequency of 2.45 GHz is promoted. A hypothesis is proposed and tested that microwave pretreatment of biomass pellets and blending of such pretreated pellets with raw pellets can be applied to enhance the thermochemical conversion of lignocellulosic biomass blends from different origin. The test results confirm that increased reactivity and heating value of pretreated biomass pellets enhances heat energy production and limits the formation of green house gases (GHG) emissions, thus advancing a more efficient usage of agricultural and forestry waste for energy production.

Published: August 2021

AbstractThe possibility of intensifying the separation of isothermal ternary gas mixtures containing carbon dioxide was studied experimentally. It was shown that the preferential transfer of carbon dioxide requires the system to be initially diffusively unstable, and the interdiffusion coefficients of mixing components can either differ significantly from each other or be close in value. A linear analysis of the stability of isothermal ternary gas mixtures containing carbon dioxide for a flat vertical channel and a cylindrical channel of finite height was performed. Comparison of the results of the numerical study with experimental data showed qualitative coherency.
Heating rate with regard to temperature release of UHPC under cyclic compressive loading
Authors: Deutscher Melchior , Scheerer Silke 
Published: August 2021

AbstractThe heating of high‐performance concrete during high‐frequency cyclic loading strongly influences the fatigue strength and has a negative influence on them. This is particularly noticeable in fatigue tests for the standardization of high‐performance concretes. In order to understand the causes and to be able to consider the strength change, effects of different parameters have to be investigated. Both the loading speed and the applied fatigue stress have a strong influence on the speed of heating up. However, from measurements during fatigue tests result curves that show not only the temperature generation but also the temperature release, making it difficult to assess the individual aspects. For this reason, a purely measurement‐based method is being developed with which the cooling can be calculated continuously over the temperature curve and thus the pure heating can be determined. This enables a better understanding of the experiments carried out so far. In this paper, the previous test results are presented, and the evaluation method is explained and applied. This partially corrects the previous understanding of the parameters. The new findings from the evaluation method on the frequency influence are verified and confirmed with three additional tests with thermal insulation.

Authors: Zeller Michael , Netsch Niklas , Richter Frank , Leibold Hans , Stapf Dieter 
Published: August 2021

AbstractChemical recycling of plastic wastes can be a useful complement to mechanical recycling to achieve the required plastics recycling rates and to establish a circular economy that is climate neutral and resource‐efficient. Different mixed plastic wastes that are subject to future recycling efforts are studied under uniform conditions of intermediate pyrolysis characterized by a medium heating rate and pyrolysis temperature. Product distributions and selected product properties are determined, and process mass and energy balances are derived. Product yields and compositions are highly dependent on the waste pyrolyzed. The results show that pyrolysis is a suitable process to recover chemical feedstock from various complex mixed plastic wastes.

Published: August 2021

AbstractThe tandem catalytic functionalization/carboxylation of double as well as triple carbon‐carbon bonds with CO2 represent an emerging research area in synthetic organic methodology. In particular, the combination of mild reaction conditions, stoichiometric acceptor/donorless conditions (visible light photoredox catalysis) and chiral catalysts contributed to a rapid development of this intriguing research area capable of creating chemical diversity/ complexity from readily available unsaturated hydrocarbons and CO2 as a C1‐buinding block. The most recent developments in the field have been collected in the present review article and organized, based on the different sets of π‐systems/intermediates/reactive partners employed (i.e., nickelalactones, organo‐halides) as well as synthetic strategies (i.e., visible‐light photo redox catalysis).

Main observation and conclusionA new cyclic thiopeptide, berninamycin F (3), three new linear thiopeptides, berninamycins G—I (4—6), and two known berninamycin derivatives, berninamycins C and D (1 and 2) were isolated from Streptomyces sp. CPCC 203702. Their structures were elucidated through HRESIMS and one‐ and two‐dimensional NMR data, and the absolute configurations were assigned using Marfey's method. Compounds 4—6 are the first examples of linear berninamycin analogs. Notably, compound 4 is the first example of linear thiopeptide with a 1‐(oxazol‐2‐yl)ethan‐1‐one group, compound 6 is the first linear thiopeptide derivative with methylated oxoacetate moiety. Compounds 1—6 exhibited excellent anti‐Zika virus activities with IC50 values in the range of 4.4—10.5 μmol/L, which were superior to that of the positive control ribavirin (IC50 = 49.2 μmol/L). Compounds 1 and 3 showed strong anti‐influenza A virus activities with the IC50 values of 15.6 and 3.2 μmol/L, respectively. Compound 1 exhibited good antibacterial activities against methicillin‐resistant Staphylococcus aureus and vancomycin‐resistant Enterococcus spp. pathogens.

Published: August 2021

AbstractThe policy‐driven “Grain for Green Programme” (GGP) has resulted in large‐scale land conversion from agricultural land to natural land in the karst area. One research surrounding the GGP is focused on evaluating its ecological implications for total mercury (THg) enrichment in Yinjiang County, Guizhou Province, Southwest China. Results show that 1) THg content in agricultural land (201.85 ± 57.23 µg kg−1) is lower compared to the forest (1048.62 ± 306.19 µg kg−1) and shrub (2582.60 ± 614.76 µg kg−1). 2) The THg content shows a good correlation with Fe (agricultural land:R= 0.75,p< 0.01; shrub:R= 0.88,p< 0.01), pH (shrub:R= 0.87,p< 0.01), and sand proportion (forest:R= −0.65,p< 0.01), rather than soil organic carbon (SOC). In the shrub, the increased pH and iron (Fe) content correspond to THg content between 1804 and 3743 µg kg−1; below the depth of 80 cm of the forest soil, the increased sand proportion correlates to THg content between 1223 and 748 µg kg−1. 3) The risk index of the THg exceeds 320 in the soil and imposes a very high ecological risk to this area.
Linking environmental management and employees' organizational identification: The mediating role of environmental attitude
Authors: Jaich Hans 
Published: August 2021

AbstractThe fundamental research question in the present study is whether perceived environmental management practices relate to employees' organizational identification. Specifically, it is hypothesized that this relationship is mediated by employees' environmental attitudes. The corresponding research model adopts a multi‐theoretical approach that combines two different theoretical lenses. Goal‐framing theory is introduced to predict whether perceived environmental management practices affect employees' environmental attitudes, while green‐person‐organization fit is applied to explain the relationship between employees' environmental attitudes and organizational identification. The research model was tested using a cross‐sectional research design with data from 206 employees from tourist service companies in Germany. The results, which largely support the research model, shed light on a thus far unexplored mechanism that mediates individual reactions to organizational practices and contrasts the more established proposition that employees first identify with their organization before they develop attitudes that are in accordance with corresponding ingroup norms. Implications for both research and practice are discussed.
The prodigiosin change on the surface of Serratia marcescens detected by flow cytometry

Published: August 2021

AbstractThe potential of flow cytometry for the study of changes in prodigiosin on the cell surface of Serratia marcescens is of academic and practical interest. This is because S. marcescens can produce prodigiosin, a secondary metabolite, with potential use as a cancer‐cell inhibitor. In this study, three groups of bacterial cultures with different carbon sources were compared, and the effect of the addition of cAMP to the sucrose‐based culture was studied. Both cellular morphology and DNA content were detected by flow cytometry, rendering a broad description of the bacterial behavior. It is the first use of flow cytometry to investigate the dynamics of prodigiosin on the surface of S. marcescens during growth in different media. The fluorescence intensity is related to the DNA content, the forward‐scattered light is related to cell volume, and the side‐scattered light is related to the surface morphology, especially the surface prodigiosin. These may contribute to the potential development of a bacterial metabolic monitoring strategy using both DNA content analysis and bacterial morphology based on flow cytometry technique.
EETSP: Energy‐efficient two‐stage routing protocol for wireless sensor network‐assisted Internet of Things

Published: August 2021

SummaryWireless sensor network (WSN) is a key technology that can support Industrial Revolution 4.0. The sensor nodes (SNs) are the important component of WSN. Recharge or repair of batteries of SNs is impossible, and thus, energy is the most valuable resource of WSN. Over the years, many methods have been proposed to conserve the precious energy resource of WSN. The most important concern in WSN is how much of the energy of the SNs can be saved, which can contribute to the better network life of WSN. WSN‐assisted IoT output is reduced when a wide region of the network is deployed. Energy‐efficient routing is one of the ways to reduce power consumption in WSNs. Therefore, a novel energy‐efficient two‐stage routing protocol (EETSP) has been proposed to reduce the energy used in WSN and extend the stability period as well as the network lifetime of WSN. Through this protocol, the number of packets communicated to the base station (BS) is significantly improved, and the cluster heads (CHs) and secondary cluster heads (SCHs) reduce the energy utilization in the network. SCH works as a backup CH. EETSP consists of two stages. The selection of CH and SCH is made in the primary stage, based on the input parameters. Intercluster routing and intracluster routing are performed in the second stage. The improvements of EETSP are examined against LEACH and Z‐SEP, and obtained results indicate that the EETSP is better in terms of stability period, throughput and network lifetime.
