Activated carbons (ACs) are a versatile group of adsorbents for water pollution control, especially organic dyes. Harsh chemicals and high temperatures are required for the activation process of ACs, which becomes a significant concern due to their toxicity and harmful effects on human health and the environment. Gamma irradiation, an alternative green technique, is a promising strategy for pretreatment and escalates the nitrogen or oxygen functional group of ACs. The current study provides the modification of ACs by the gamma irradiation in the various pH (5-11) of urea solution. The modified ACs were characterized by scanning electron microscopy (SEM), nitrogen gas adsorption-desorption analysts (BET), temperature program desorption (TPD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, and X-ray diffraction spectroscopy (XRD). The point of zero charges and dye adsorption capacities were determined. This finding demonstrates that the ACs can be modified by gamma irradiation at 25 kGy in the urea solution media. The degree of graphitization enhanced significantly at pH 11(AC-pH11). The oxygen-rich functional groups created by radiation assists could enhance the electrostatic attraction between acid gases or cationic dyes. AC-pH11 also was able to adsorb methylene blue (160.73 ± 1.70 mg/g) greater than methyl orange (127.57 ± 2.22 mg/g).

Published: November 2021

The present study evaluated the engineering properties and microstructure of an alternative binder composed of calcium carbide residue and silica fume. The cementitious mechanisms of this alternative binder based on the pozzolanic reaction in raw materials. The ratio of calcium carbide residue and silica fume was decided based on the chemical composition of raw materials and their chemical reaction. The calcium carbide residue-silica fume mortar was prepared and tested for its compressive strength at several curing periods, with results then compared to conventional mortar made with ordinary Portland cement. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) were used to investigate the microstructure of hardened mortars. The test results suggest that the compressive strength of calcium carbide residue-silica fume mortar continuously developed throughout the curing period. The relative compressive strength of calcium carbide residue-silica fume mortar reached 72.78% of the ordinary Portland cement mortar strength at 28 days curing age.

Published: November 2021

Ongoing studies show that an effective demand for using natural fibers as a substitution of an artificial fiber in fiber-reinforced composites formation has increased their applicability in an industrial area worldwide. The hydrophobic nature of natural fiber makes week adhesion among the cellulose fiber and matrix components; these problems are usually encountered in fiber-reinforced composites production. To overcome such a limitation of a cellulose fiber, specific physical and chemical treatment strategies were advised by researchers around the world for surface modification of natural cellulose fibers. One of the most basic and efficient surface modification approaches adopted today by the researchers was alkali treatment, widely used in natural fiber composites formation. This technique effectively improved the Mechanical property of natural cellulose fiber, such as tensile strength and flexural properties, while the impact strength result was reduced.

Authors: Zong Nan Fu , Sun Wei Zhao , Liang Xing Hong , Jing Tao
Published: November 2021

Coarse columnar dendrite greatly reduced the mechanical performance of GH3039 nickel-based alloy in the additive manufactured parts, which limited its application in the engineering fields. This study provides a comparison of overgrowth behaviors at diverging grain boundaries through two-dimensional phase field simulation, and the effect of dendrite orientation on overgrowth behavior was analyzed. Moreover, our results show that the primary spacing becomes larger as the increasing of dendrite orientation. The columnar dendrites branch new dendrites near grain boundaries to refine the primary arm spacing in the process of wire and laser additive manufacturing (WLAM).

Published: November 2021

The dilution ratio of the Ni coating prepared by the laser cladding under the assistance of the follow-up feeding pulsed current was optimized by combining back propagation (BP) neural network and genetic algorithm. The model was trained according to the results of the 6-factor 3-level orthogonal experiments. A BP genetic neural network forecast model between cladding parameters (laser power, scanning speed, powder feeding rate, pulsed current, pulse frequency and pulse width) and dilution ratio of coating was constructed. On this basis, technological parameters under the target dilution ratio of the coating were optimized by a genetic algorithm. Results demonstrated that the predicted results of the model are very close to the experimental results in term of dilution ratio of the coating, with a relative error no higher than 2.63%. This demonstrates that the model is reliable and effective. The optimal technological parameters are gained when the dilution ratio of the coating is 17.5%, including laser power=1926.3 W, laser scanning speed =·s-1, powder feeding rate= ·min-1, average pulsed current =, pulse frequency=445.6 Hz, pulse width= 108.4 μs.

Published: November 2021

Hard coatings applied by the Physical Vapor Deposition method often provide very good mechanical properties, especially when applied to metal parts that are mentioned to withstand certain level of wear. In this study, TiN coating combined with deep rolling were applied to the investigated steel samples, prepared by powder metallurgy and subjected to contact-fatigue stress. Computational analysis of stress states in samples by the finite element method helped to reveal the behavior and formation of fatigue failures when loading samples. The results, processed in the form of fatigue curves, probabilistic Weibull curves using metallography and electron microscopy, showed a positive effect of the used coatings and their combination with other surface treatments on the contact-fatigue strength of the examined samples. Microscopic study also showed the different mechanisms of crack formation and of crack propagation rate due to contact loading of material with a laser hardened surface, which has an obvious impact on material lifetime.

Published: November 2021

In this paper, the physical and chemical analysis method was used to analyze the leakage of a regeneration gas heater device accident. The result shows that this device was heated seriously at local area, and oxidized severely. The carbon content around the leakage is obviously lower than the limit of standard, and the grain deformation at crack tip of the leakage is obvious.It shows that reason of device failure is caused by typical plastic Instability, and low carbon content leads to insufficient mechanical properties at high temperature. According to data from manufacturer, the unreasonable arrangement of thermo-couples may be the root cause of this leakage.It can be considered that replace the higher grade materials conservatively, while optimizing the arrangement of thermo-couples.
Microstructure Evolution of AS41 Magnesium Alloy in ECAP
Authors: Pi Zong Li , Zhang Xiao Feng , Ling Zhang , Li Ying Long
Published: November 2021

ECAP is a continuous multi-pass extrusion process that enables the specimen to obtain considerable cumulative deformation to refine the grain. In this paper, ECAP was used to deform AS41 magnesium alloy at 350°C, and the microstructure was observed and analyzed. The results show that the ECAP process has excellent effect on grain refinement and uniform microstructure. The grain size of AS41 decreases from 200μm to 20μm, and the microstructure is more uniform than that of as-cast sample. The reason is that the original grain is broken and refined under the action of shear force, and dynamic recrystallization occurs at the same time, resulting in small recrystallized grains. The Mg2Si particles were redistributed during ECAP and uniformly distributed in the crystal in rod shape.

Published: November 2021

In order to study the influence of different initial topography on the molten pool flow under a moving heat source, the finite element analysis method was used to establish a two-dimensional transient model of laser polishing to simulate the evolution of the surface topography of the material during laser polishing. In the simulation process, a moving laser beam was used as the heat source, and the free surface of the actual material was profiled through a three-dimensional profiler. A very similar simulation model surface was constructed, coupled with the flow field and temperature field in the laser polishing process, and the capillary force was considered comprehensively. Combined with thermocapillary force. The results show that under the combined action of capillary force and thermocapillary force, the surface of the polished material has a peak-filling effect, which makes the surface of the material achieve a good polishing effect. The initial shape will affect the polishing effect, the greater the curvature, the faster the flow rate of the molten pool. In molten pools with large spatial curvatures, capillary forces dominate.

Published: November 2021

Hepatocyte transplant represents a treatment for metabolic disorders but is limited by immunogenicity. Our prior work identified the critical role of CD8+ T cells, with or without CD4+ T cell help, in mediating hepatocyte rejection. In this study, we evaluated the influence of invariant NKT (iNKT) cells, uniquely abundant in the liver, upon CD8-mediated immune responses in the presence and absence of CD4+ T cells. To investigate this, C57BL/6 (wild-type) and iNKT-deficient Jα18 knockout mice (cohorts CD4 depleted) were transplanted with allogeneic hepatocytes. Recipients were evaluated for alloprimed CD8+ T cell subset composition, allocytotoxicity, and hepatocyte rejection. We found that CD8-mediated allocytotoxicity was significantly decreased in iNKT-deficient recipients and was restored by adoptive transfer of iNKT cells. In the absence of both iNKT cells and CD4+ T cells, CD8-mediated allocytotoxicity and hepatocyte rejection was abrogated. iNKT cells enhance the proportion of a novel subset of multipotent, alloprimed CXCR3+CCR4+CD8+ cytolytic T cells that develop after hepatocyte transplant and are abundant in the liver. Alloprimed CXCR3+CCR4+CD8+ T cells express cytotoxic effector molecules (perforin/granzyme and Fas ligand) and are distinguished from alloprimed CXCR3+CCR4−CD8+ T cells by a higher proportion of cells expressing TNF-α and IFN-γ. Furthermore, alloprimed CXCR3+CCR4+CD8+ T cells mediate higher allocytotoxicity and more rapid allograft rejection. Our data demonstrate the important role of iNKT cells in promoting the development of highly cytotoxic, multipotent CXCR3+CCR4+CD8+ T cells that mediate rapid rejection of allogeneic hepatocytes engrafted in the liver. Targeting iNKT cells may be an efficacious therapy to prevent rejection of intrahepatic cellular transplants.

H2-O (human HLA-DO) is a relatively conserved nonclassical MHC class II (MHCII)–like molecule. H2-O interaction with human HLA-DM edits the repertoire of peptides presented to TCRs by MHCII. It was long hypothesized that human HLA-DM inhibition by H2-O provides protection from autoimmunity by preventing binding of the high-affinity self-peptides to MHCII. The available evidence supporting this hypothesis, however, was inconclusive. A possibility still remained that the effect of H2-O deficiency on autoimmunity could be better revealed by using H2-O–deficient mice that were already genetically predisposed to autoimmunity. In this study, we generated and used autoimmunity-prone mouse models for systemic lupus erythematosus and organ-specific autoimmunity (type 1 diabetes and multiple sclerosis) to definitively test whether H2-O prevents autoimmune pathology. Whereas our data failed to support any significance of H2-O in protection from autoimmunity, we found that it was critical for controlling a γ-herpesvirus, MHV68. Thus, we propose that H2-O editing of the MHCII peptide repertoire may have evolved as a safeguard against specific highly prevalent viral pathogens.

Metabolism and inflammation have been viewed as two separate processes with distinct but critical functions for our survival: metabolism regulates the utilization of nutrients, and inflammation is responsible for defense and repair. Both respond to an organism’s stressors to restore homeostasis. The interplay between metabolic status and immune response (immunometabolism) plays an important role in maintaining health or promoting disease development. Understanding these interactions is critical in developing tools for facilitating novel preventative and therapeutic approaches for diseases, including cancer. This trans–National Institutes of Health workshop brought together basic scientists, technology developers, and clinicians to discuss state-of-the-art, innovative approaches, challenges, and opportunities to understand and harness immunometabolism in modulating inflammation and its resolution.

Skin reactions after transarterial chemoembolization (TACE) with anthracyclines are rare and mostly limited to small areas. We describe a 56-year-old male with hepatocellular carcinoma treated with epirubicin chemoembolization. Immediately the procedure, pain on the right side and an extended livedo reticularis-like skin reaction appeared. Since dexrazoxane, a topoisomerase-II catalytic-cycle inhibitor, has been shown to be effective in preventing or reducing skin necrosis and ulceration following anthracycline extravasation, the drug was administered 8 h after TACE and repeated in the following 2 days. Due to marked extrahepatic diffusion of epirubicin as evidenced by computed tomography imaging, the patient showed signs of systemic organ involvement. The critically ill patient required close follow-up and intensified treatment including blood supply and pulmonary drainage of a pleural effusion. The patient presented a significant clinical improvement of the skin lesions and resolution of organ involvement with normalization of laboratory parameters after dexrazoxane. In conclusion, adverse extended skin reactions and severe systemic effects related to anthracyclines diffusion could be properly treated with dexrazoxane infusion.

Chaetomium sp. is a mold, member of the phylum Ascomycota. Clinical disease in humans is rare, particularly in children, for which only five cases have been reported. We report a 7-months-old female patient with a diagnosis of visceral heterotaxy syndrome who was admitted to a private center in Mexico. After two episodes of focal myoclonic seizure, a brain magnetic resonance imaging (MRI) revealed a right porencephalic cyst and a right frontal abscess with ventriculitis. Seventy-two hours after temporal abscesses drainage procedure, the culture showed a rapidly growing pale white fungal colony. Sequencing of internal transcribed spacer (ITS) and D1/D2 led to the identification of Chaetomium strumarium. Although Chaetomium sp. is a rare fungal infection in humans, clinicians should consider it as a plausible etiologic agent that can form brain abscess.

IMPROVING PRODUCTION EFFICIENCY IN THE ICE CREAM INDUSTRY
Authors:   Institute for Information Technologies, University of Kragujevac, Veselinović Nevena , Nikolić Jelena
Published: November 2021

The food industry is a large consumer of energy that depends on fossil fuels, the combustion of which releases large amounts of CO2. The paper examines the possibility of reducing the use of non – renewable energy sources through a detailed energy audit and consideration of measures to increase energy efficiency and renewable energy sources in the ice cream craft industry. The cost-effectiveness of the proposed measures is observed for two scenarios. The first scenario covers the current situation in Serbia, in which there are no carbon taxes, and the price of energy is relatively low compared to other countries in Europe. The second „German scenario“ implies carbon taxes in the amount of 55€/tCO2, which is expected to, with the same energy prices, significantly reduce the repayment period and affect the ranking of measures. The analysis is performed to consider how the carbon tax reflects on the motivation of craft producers to improve energy efficiency.

In this study, HPLC-DAD rapid analysis of phenols in wine samples was performed. The recording was performed at different wavelengths: phenolic acid (254nm), flavan-3-ols and stilbene (280nm), flavonoids (340nm) and anthocyanins (520nm). In selected wines, the concentrations of the following compounds were determined and expressed in mg/l of wine. The isolated derivatives were: hydroxybenzoic acids, derivatives of caffeic, ferulic, syringic, and vanillic acids, catechin (flavanol), rutin, myricetin and quercetin (flavonols), and the stilbene derivative-resveratrol. The properties and quantities of phenolic compounds in organic wines were investigated. The results show the content of phenolic compounds in organic wines do not differ qualitatively and quantitatively from those in conventional wines. Wine samples have shown good antioxidative activity according to both DPPH and FRAP analysis, which indicates the good antioxidative potential and high antioxidant concentration in tested wines. Cabernet Sauvignon wines have shown better radical scavenging activity than Merlot, especially when the DPPH test was considered.
Die EU-Taxonomie als Webereiter für Nachhaltig(er)e Chemie?
Authors: Rittmeier Aaron
Published: November 2021

Mit der Chemikalienstrategie für Nachhaltigkeit visiert die EU einen grünen Transformationsprozess der Wertschöpfungsketten der chemischen Industrie an. Dieser Transformationsprozess erfordert jedoch große Mengen an finanziellen Ressourcen. Die EU hat diesbezüglich die (EU) 2020/852 Taxonomie-Verordnung (EU-Taxonomie) verabschiedet, welche unionsweit einheitliche Kriterien für „ökologisch nachhaltige“ Wirtschaftstätigkeiten definiert, um die Transparenz auf den Finanzmärkten zu erhöhen und somit ab 2022 massive private Kapitalströme in nachhaltigere Investitionen und Wirtschaftsaktivitäten umzulenken. Die Arbeit prognostiziert die Wirksamkeit und den potenziellen Beitrag dieses Instruments zu einer nachhaltig(er)en Entwicklung der chemischen Industrie. Unter Anwendung der transdisziplinären Delta-Analyse (TDA) nach Bizer & Führ schätzt die Abhandlung hierzu die potenziellen Auswirkungen des Instruments auf das Verhalten der Investoren sowie der Akteure der chemischen Wertschöpfungsketten ab. Darüber hinaus untersucht der Text die vorläufigen Technischen Regulierungsstandards der EU-Taxonomie zum Umweltziel Klimaschutz für die Herstellung von organischen Grundstoffen und Chemikalien (Stand März 2021) und analysiert diese mit Blick auf die Anforderungen an eine nachhaltig(er)e Chemie. Daraus ergeben sich strukturelle sowie inhaltliche Limitationen des Instruments in der aktuellen Form, welche zu Opti-mierungspotenzialen hinleiten, mit denen die EU-Taxonomie zukünftig stärker zum Transformationsprozess zu einer nachhaltig(er)en Chemie beitragen kann. Eine zentrale Erkenntnis ist jedoch, dass durch die EU-Taxonomie keine produktbezogenen Betrachtungen entlang der chemischen Wertschöpfungsketten gefördert wird, womit das Instrument schlussendlich nicht als alleiniger Wegbereiter für eine nachhaltig(er)e Chemie fungieren kann.

Published: November 2021

Global scale changes in land use affect biodiversity, global climate, and ecosystem services. Integrating a local and regional ecosystem service approach into plans and policies levels is essential for sustainable land management. In this study, land use/land cover differences in Adana-Karaisali district of Turkey were investigated using Normalized Difference Vegetation Index (NDVI). Landsat satellite images of the area from 2000 and 2016 were analyzed using ISODATA method and 16 land use were identified based on the third level of the CORINE classification framework. The results showed that the biggest changes occurred in agricultural areas, 2.57% decrease in non-irrigated arable land while a 7.14% increase was observed in permanently irrigated lands. In spite of the decrease in the number of inhabitants in the area, continuous urban fabric increased at the rate of 0.07% and 7.62% increase was observed in forest lands. The positive or negative effects of the identified changes on ecosystem services based on the Common International Classification of Ecosystem Services (CICES) framework were evaluated. In the case of Karaisalı, in spite of the decrease in water bodies and natural landscapes, it has been observed that increases in agricultural areas, forests, and artificial surfaces positively have affected ecosystem services valuation in the district.
EDITORIAL : A research priority for biodiversity conservation
Authors: Margules Chris
Published: November 2021

Conservation biology emerged as a scientific discipline in the mid-1980s with the explicit practical goal of conserving species and habitats. The term ‘biodiversity’ was coined soon after, apparently at some time during the organization of the September 1986 National Forum on Biodiversity held by the US National Academy of Sciences and the Smithsonian Institution. The science of conservation biology was quickly taken up. Journals proliferated and textbooks soon followed. Laboratories within university biology and ecology departments specialized in conservation biology. Along with a great many other young biologists and ecologists, I climbed the moral high ground and set about research to help change the future by discovering how to protect biodiversity.

The painted bat, Kerivoula picta (Pallas, 1767) is considered one of the most aesthetically appealing bats in Sri Lanka with bright orange fur and black wings. However, very little information is available with regard to the ecology of this species in both local and global contexts. Of its roosting habits, Phillips (1980) reports that in Sri Lanka the bat is usually found roosting among banana leaves while it has been observed utilising tall grass species and even an abandoned nest of a Baya Weaver (Plocius philippinus) for this purpose. Here we report an observation of the species using a man-made artefact for roosting during the day.
