Chemobrionic Sponge-Mimetic Tubules for Probing the Template-Assisted Evolution of Ocean Sponges and Bioengineering Applications

This work expands the scope of chemobrionic chemistry to produce biopolymer-intercalated inorganic tubes that structurally and chemically resemble both oceanic hydrothermal vent tubules and the scaffolds of tubular sponges. The sponge-mimetic tubules (SMTs) are formed by seeding calcium chloride into a solution of concentrated sodium silicate-potassium phosphate containing solubilized biopolymers of the cyanobacterial origin. A carbonation step to increase the calcium carbonate content in the SMTs was optimized. Incorporation of biopolymers into the fabric of the SMTs was confirmed by energy-dispersive Xray microanalysis and infrared spectroscopy and the mineral components identified by X-ray diffraction. SMT morphology was characterized by scanning electron microscopy. Experiments testing the hypothesis that biohybrid hydrothermal tubules in Paleoproterozoic oceans served as sites where unicellular eukaryotes colonized and evolved into early ocean sponges were performed: the compatibility of the SMTs with marine cells was demonstrated by live cell imaging of Pyrocystis lunula seeded onto alginate-incorporated SMTs. The choanoflagellate cell line Salpingocea rosetta, considered the ancestor of sponge choanocytes, was seeded onto alginate SMTs. Live cell imaging and confocal laser scanning microscopy confirmed the viability of the cells and actively feeding choanoflagellate cell assemblies on the SMTs were captured by video microscopy. The findings suggest that these hydrothermal vent models can support diverse eukaryotic life and validate the theory of a chemobrionic-linked origin of ocean sponges. The potential of using SMTs for tissue engineering was explored by using them as scaffolds for 3D cell culture of human fibroblasts.

Application of deep eutectic solvents as a green and biodegradable media for extraction of anthocyanin from black carrots

Deep eutectic solvents (DESs) not only could keep a high extraction efficiency, but also could easily be applied to pharmaceutical and food products. This study aimed to set out an eco-friendly technique for the anthocyanin extraction from natural sources. In this study, DESs coupled with ultrasound-assisted extraction (UAE) were considered as an alternative green method to classical applications. The choline chloride-based DESs was prepared with the hydrogen bond donor. The conventional, UAE and DES extraction methods were studied and compared. Citric acid was selected as the most promising hydrogen bond donor for the preparation of DES. The results showed that the biodegradability of all tested DESs was >80% after 28 days. Based on the analyses, it could therefore be assumed that all of the analysed DESs were biodegradable green solvents. The results of FT-IR revealed that pure choline chloride demonstrated several functional groups and many of these functional groups coexisted after DES formation. Thermogravimetric analysis (TGA) showed that all the DESs and their components were degraded in a single stage and the polymeric colour ratio was lower if acid was present in the DES composition. The results indicated that the developed method could be regarded as a sustainable, effective, and green approach for anthocyanin extraction.

Fate of typical organic halogen compounds during electrodialysis process and improvement of their recoveries

According to an earlier study, electrodialysis (ED) can efficiently separate most organic halogenated micro pollutants from inorganic halogens (i.e., halides and oxyhalides) in water, with only a few micropollutants being poorly-recovered. To optimize the ED process and to gain in-depth knowledge of the mechanisms responsible for their low recoveries, this study designed some experiments to examine the fates and transports of three hard-to separate organic halogen compounds. Results show that the dominant mechanism responsible for the loss of trichlorophenol (TCP) is migration and retention in the ion exchange membrane (IEM), the dominant mechanism for the loss of trichloroacetic acid (TCAA) is ion exchange with the IEM, and the dominant mechanism for the loss of trichloroacetonitrile (TCAN) is volatilization and chemical decomposition during the ED process. Optimizing specific operating conditions (e.g., sealing, voltage, and membrane type, etc.) can improve recovery of these micropollutants to 70.4-95.8% while maintaining 90.4-99.5% removal of chloride. Even though TCAN underwent hydrolysis, we recovered 82.0% chlorine from TCAN and its hydrolytic products. These results may help not only better understand the fates and transports of organic micropollutants during the ED process, but also help facilitate application of electrodialysis technique for measuring total organic halogen.

Comparing desorption properties of pollutants on bentonite particles and in compacted bentonite

Desorption is one of the main factors causing groundwater and soil pollution. Therefore, the study of clay desorption characteristics is important for the prediction of groundwater and soil pollution. In previous studies, batch tests and column tests were used to study the desorption characteristics of pollutants on clay. However, the desorption parameters obtained via the two test methods were often quite different. To investigate differences in the desorption characteristics of different pollutants on clay particles and in compacted clay, batch and column desorption tests were conducted using cadmium chloride, fulvic acid, and sodium phosphate as the adsorbates and bentonite as the adsorbent. It was found that the unit particle surface area desorption distribution coefficients of pollutants on bentonite particles were approximately equal to the unit pore surface area distribution coefficients of pollutants in compacted bentonite. This indicates that the desorbed amount per unit of surface area is basically consistent, regardless of whether they are sorbed on particles or in compacted bentonite. A simple formula for determining the desorption retardation factor of pollutants in compacted bentonite is presented. The results of this study provide a reference for the prediction and evaluation of groundwater and soil pollution.

Sustainable application of processed TBM excavated rock material as green structural concrete aggregate

In this study, we investigate the potential use of the material excavated by tunnel boring machines (TBMs) as structural concrete aggregate. Accordingly, several experimental and statistical investigations on the mechanically and thermally processed material were carried out. The raw TBM excavated material contained a considerable amount of macro-micro quartz sand. Additionally, the poor-grain size distribution of the TBM material and its weak interface bonding demonstrated the impracticality of using it as a sand filler. Microstructural investigations of the crushed limestone material revealed that around 20% of it was composed of calcium carbonate, whereas no pozzolanic compounds were observed. The results indicate that the TBM excavated material can be used as a structural concrete aggregate. The properties of the fresh TBM-aggregate-based concrete were well within the acceptable range. The porosity and chloride diffusivity of the TBM-aggregate-based concrete mixtures were slightly higher than those of the control mixture. The aggregate processing method had a negligible influence on the strength and durability of the concrete. Furthermore, the concrete porosity and permeability exhibited a decreasing trend with the increase in the TBM aggregate content. The compressive strength of the TBM aggregate concrete was less than that of the control mixture. However, thermal treatment of the TBM aggregate can reduce this loss in strength. In addition, reasonably reliable isoresponse models were developed to predict the strength and durability of the TBM-aggregate-based concrete. (C) 2020 Elsevier Ltd. All rights reserved.

High-throughput thin-film composite membrane via interfacial polymerization using monomers of ultra-low concentration on tannic acid – Copper interlayer for organic solvent nanofiltration

In this work, a novel organic solvent nanofiltration (OSN) membrane was engineered precisely via interfacial polymerization on the surface of an interlayer which was in-situ constructed using tannic acid – copper (TA-Cu) complex on the surface of a polyimide substrate membrane, and then was followed by crosslinking and activation procedures. The most promising aspect of this work is the high separation and solvent permeation performances due to the ultrathin film obtained in the interfacial polymerization reaction using ultra-low concentration monomers, 0.025 wt% aqueous m-phenylenediamine (MPD) and 0.0050 wt% trimesoyl chloride (TMC) in organic solution, respectively The optimized interlayered thin film composite (TFC) OSN membrane achieved a rejection of 98.36% for Rose Bengal (RB, 1017 Da) and a DMF permeance of 150.05 L m(-2)h(-1) MPa-1 for 100 mg L-1 RB-DMF solution, much higher than most of the state-of-the-art literature works. Furthermore, after a 75 h’ filtration, it remained a 98.7% rejection for RB of the RB-DMF solution, proving a high resistance to strong polar solvent. Meanwhile, it has an average surface roughness of less than 4.5 nm, a thickness of about 15 nm for the PA skin layer. This OSN membrane fabrication strategy is much economical and much environmentally friendly, and shows great potential for the application in the separation of organic solvent systems.

Reliable Method for Fabricating Tissue-Mimicking Materials With Designated Relative Permittivity and Conductivity at 128 MHz

Artificial materials that can simultaneously mimic the relative permittivity and conductivity of various human tissues are usually used in medical applications. However, the method of precisely designing these materials with designated values of both relative permittivity and conductivity at 3 T MRI resonance frequency is lacking. In this study, a reliable method is established to determine the compositions of artificial dielectric materials with designated relative permittivity and conductivity at 128 MHz. Sixty dielectric materials were produced using oil, sodium chloride, gelatin, and deionized water as the main raw materials. The dielectric properties of these dielectric materials were measured using the open-ended coaxial line method at 128 MHz. Nonlinear least-squares Marquardt-Levenberg algorithm was used to obtain the formula, establishing the relationship between the compositions of the dielectric materials and their dielectric properties at 128 MHz. The dielectric properties of the blood, gall bladder, muscle, skin, lung, and bone at 128 MHz were selected to verify the reliability of the obtained formula. For the obtained formula, the coefficient of determination and the expanded uncertainties with a coverage factor of k = 2 were 0.991% and 4.9% for relative permittivity and 0.992% and 6.4% for conductivity. For the obtained artificial materials measured using the open-ended coaxial line method, the maximal difference of relative permittivity and conductivity were 1.0 and 0.02 S/m, respectively, with respect to the designated values. In conclusion, the compositions of tissue-mimicking material can be quickly determined after the establishment of the formulas with the expanded uncertainties of less than 10%.

Characterisation and antioxidant activity of glycated casein hydrolysate with xylose: Impacts of zinc sulphate and cupric chloride

Impacts of zinc sulphate and cupric chloride on characteristics and antioxidant capacities of glycated products (GPs) derived from casein hydrolysate (CH) and xylose were studied. The browning degree of xylose-CH GPs was the largest at zinc sulphate addition of 15 mg L-1, while its browning degree increased with cupric chloride extended from 0 to 15 mg L-1. Loss of free amino groups, fluorescence intensity and the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging capacity of xylose-CH GPs increased with the increase of cupric chloride addition, but loss of amino groups, fluorescence intensity and DPPH radical scavenging capacity were largest at the zinc sulphate addition of 15 mg L-1. The addition of zinc sulphate and cupric chloride promoted production of higher and smaller molecular substances in xylose-CH GPs and CH. Therefore, zinc sulphate and cupric chloride promoted glycated reaction of xylose and CH and enhanced antioxidant activity of xylose-CH GPs. (C) 2020 Elsevier Ltd. All rights reserved.

Sodium alginate/bismuth (III) oxide composites for gamma-ray shielding applications

In the present work, we have explored the efficacy of bismuth (III) oxide (Bi2O3) loaded, calcium ion cross-linked solution cast sodium alginate composite films for radioprotective applications. Calcium ion cross-linking increased the water and chemical resistance, which further improved on introduction of Bi2O3 into the composites. The 40 wt% Bi2O3 loaded films showed good heat resistance with the peak degradation temperature reaching as high as 251 degrees C. The Bi2O3 loaded composites showed enhanced tensile strength (TS) and Youngs modulus (YM). Compared to high-modulus polymers like epoxy, high-density polyethylene (HDPE) and poly (vinyl chloride) (PVC), these exhibit relatively greater extent of stretching before breaking. The gamma-ray attenuation experiments showed that mass attenuation coefficients of the composites at various gamma-ray energies increased with filler loading. These composites are effective in shielding gamma-rays from radioactive sources like Cs-137, Na-22, Ba-133, and Co-60 that are widely employed in several medical and industrial applications. The overall enhancement in thermal, mechanical, and radiation shielding characteristics of the composites may be attributed to the uniform distribution of the fillers in alginate matrix. These nontoxic sodium alginate/Bi2O3 composites can be used as soft and biodegradable radiation shields, which may be processed to wearable forms.

Durability of recycled aggregate thermal insulation concrete under combined flexural loading and freeze-thaw cycles

A testing program including freeze-thaw cycles and flexural-loading combined action was designed to investigate the durability of recycled aggregate thermal insulation concrete (RATIC). The volume replacement ratios of recycled coarse aggregates (RCAs) were 0, 30, 50, 70, and 100%, and the flexural-load ratios were 0, 15, 30, 45%, and the glazed hollow bead particles (GHBs) with volume percentage of 130% were added. To evaluate the performance of RATIC, the relative dynamic modulus of elasticity (RDME) and mass loss rate (MLR) were estimated. The results show that the flexural-load stress exhibited an obvious negative effect on the freeze-thaw resistance of RATIC. With a 45% flexural-load ratio, RATIC fractured even before the load cycles reached 30. The decrease in the RDME was accelerated by the flexural-load stress, whereas this stress exhibited little effect on MLR. The durability performance of RATIC under combined actions decreases with the increase in the RCA replacement ratio, whereas the performance increased with the increment in the thermal insulation aggregate GHBs. Further to reveal the mechanism of RATIC under double actions, scanning electron microscopy, X-ray diffraction, and a new method of fluorescence analysis were employed. The results showed the existence of more micropores and microcracks in the tensile area. Further, compared to the new interfacial transition zones (ITZs), the microcracks in old ITZs caused by combined actions aggravated the damage caused in the freeze-thaw cycles.
