Calcium-silicate-hydrate seeds as an accelerator for saving energy in cold weather concreting

Cold weather concreting is well-known for its high energy consumption and carbon emissions because it needs to take various measurements to prevent the frost damage of concrete. Effectively promoting the strength of concrete developed rapidly in cold weather is a crucial way to solve this problem. In this study, the chloride-free and green calcium-silicate-hydrate (C-S-H) seeds were used to modify the performance of Portland cement (PC) at the negative temperature. The results showed that the strength of PC adjusted by C-S-H seeds developed rapidly at negative temperature (-5 degrees C) within 28 d after several hours pre-curing; its strength value at 28 d (74.2 MPa) was comparable with that of PC cured at room temperature for 28 d (75.3 MPa). The addition of C-S-H seeds significantly accelerated the early hydration of PC during pre-curing and the subsequent hydration at negative temperature. The freezing point and the frozen water of cement paste were significantly reduced by C-S-H seeds and pre-curing, which can help to prevent the cement matrix from frost damage at -5 degrees C. This advantage was further demonstrated by the improvement of the microstructure caused by ice. The easy-operate and green method can significantly decrease energy consumption and CO2 emissions in cold weather concreting. (C) 2020 Elsevier Ltd. All rights reserved.

Blue Perovskite Light-Emitting Diodes: Opportunities and Challenges

Metal halide perovskites are considered as promising candidates for lighting applications owing to their excellent optoelectronic properties, such as high electron/hole mobility, high photoluminescence quantum yield, high color purity, and facile color tunability. In recent years, perovskite light-emitting diodes (LEDs) have developed rapidly, and their external quantum efficiencies (EQEs) have exceeded 20% for green and red emissions. However, the EQEs and stabilities of blue (particularly deep-blue) perovskite LEDs are still inferior to the green and red counterparts, which severely restricts the application of perovskite LEDs in high-performance and wide color gamut displays as well as white light illumination. Therefore, summarizing the development of blue perovskite LEDs and discussing the opportunities and challenges associated with their future applications will help to guide the further development of the entire perovskite LED field. In this review, according to the emission color, we divide the blue perovskite LEDs into three parts for a better discussion, i.e., the emissions in the sky-blue, pure-blue, and deep-blue regions. We introduce their developed history and discuss the basic strategies to achieve blue emission. There are three typical methods to obtain perovskite emitters with blue emission, i.e., (1) composition engineering, (2) dimensional engineering, and (3) synthesis of perovskite nanocrystals and quantum dots. For composition engineering, changing ions in perovskite ABX3 structure can easily tune the perovskite emission color, particularly while changing the anions in X position. Therefore, modulating the ratio between the X-site anions of Br- and a- can cause perovskites to emit blue photons ranging from 420 to 490 nm, which almost covers the entire blue spectrum. For dimensional engineering, perovskite materials can form a series of low-dimensional structures (layered structures) with the insertion of organic ligands between the perovskite frameworks. This type of low-dimensional perovskite material typically exhibits better lighting properties than those exhibited by its three-dimensional counterpart owing to its unique charge or energy transfer process of charge carriers. Blue perovskite nanocrystals and quantum dots with high photoluminescence quantum yields are excellent candidates for realizing high-performance pure-blue and deep-blue devices because they can easily incorporate a- in their crystals, which is considerably limited in perovskite thin films owing to the poor solubility of inorganic chloride sources in polar solvents. Furthermore, we discuss several challenges associated with blue perovskite LEDs, such as the inferior device performance in the pure-blue and deep-blue regions, difficulty in hole injection, electroluminescence (EL) instability of mixed halide perovskite systems, and lagged operation lifetime, and introduce potential solutions accordingly. Note that the challenges faced by blue perovskite LEDs are also the opportunities for research in this area. Therefore, this review is of a great reference value for the next evolution of blue perovskite LEDs.

NiFe2O4-rGO/ionic liquid modified carbon paste electrode: An amplified electrochemical sensitive sensor for determination of Sunset Yellow in the presence of Tartrazine and Allura Red

In this paper, using a carbon paste electrode (CPE) modified with 1-ethyl-3-methylimidazolium chloride as an ionic liquid (IL) and NiFe2O4-rGO nanocomposite (IL/NiFe2O4/rGO/CPE), a sensitive and effective electrochemical sensor is applied to analyze Sunset Yellow. The X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) with Energy Dispersive X-Ray Analysis (EDX) and Fourier-transform infrared spectroscopy (FTIR) are employed to characterize the synthesized NiFe2O4-rGO nanocomposite. The oxidation peak currents of colorants were obtained by CV and DPV techniques; and as a result, the two linear ranges from 0.05 to 30 mu M (R-2 = 0.9939) and 30 to 500 mu M (R-2 = 0.9953) along with LOD of 0.03 mu M for Sunset Yellow is obtained. The proposed sensor is successfully applied to determine the Sunset Yellow, Tartrazine and Allura Red in PBS (pH 3). The IL/NiFe2O4/rGO/CPE displays a high performance for analysis of these dyes in hair shampoo and an orange juice as real samples with acceptable results.

Neutralization inhibition mechanism of lithium nitrite and its effect on the microstructure of mortar

The effects of calcium nitrite on corrosion inhibition of rebar in concrete have been well established. Increase in compressive strength of concrete and decrease in penetration of chloride ion have been reported. However, the effect of lithium nitrite on durability of concrete is less understood. Hence, the performance of lithium nitrite against penetration of chloride ion and neutralization in mortar were experimented. Specimens containing lithium nitrite at different replacement ratio (0%, 5%, 12.5% and 25% of total mixing water) were cured under different conditions and subjected to accelerated neutralization. Ion analysis and characterization showed a substantial increase in neutralization inhibition with the addition of lithium nitrite. The decrease in calcium and increase in lithium ions were confirmed in the regions penetrated by carbon dioxide. Under any curing condition, 25% replacement of lithium nitrite showed the presence of Li+ concentration of about 40 mg/L around the specimen surface and more than 20 mg/L at all depths after promotion of neutralization. The internal pH of mortar was maintained at 12 or above for replacement ratio above 12.5% through the production of lithium hydroxide, even if calcium hydroxide was consumed by carbon dioxide. Both Li+ and moisture content affected the degree of neutralization inhibition. (C) 2020 Elsevier Ltd. All rights reserved.

Removal of rare-earth fission products from molten chloride salt used in pyroprocessing by precipitation for consolidation into glass-bonded sodalite waste form

As an alternative method to absorption into zeolite-A for removing rare-earth (RE) fission products (FPs) accumulated in spent molten chloride salt generated by the pyrometallurgical reprocessing of spent nuclear fuel, the precipitation of the RE FPs followed by consolidation into a glass-bonded sodalite waste form has been proposed to reduce the waste volume. Chemical forms of the precipitates generated by the addition of Li2O or Li2CO3 in LiCl-KCl melts containing chlorides of REs were identified. Then, the salt adhering to the Gd2O3 precipitate, which was generated by the addition of Li2O into LiCl-KCl molten salt containing GdCl3, was removed by vacuum distillation. The distillation product or its simulant (Gd2O3) was mixed with zeolite-A and fresh zeolite, and then consolidated into glass-bonded sodalite under uniaxial pressing at the maximum temperature and pressure of 915 degrees C and 1.3 x 10(5) Pa, respectively. Examinations of the consolidated products showed that a dense product was fabricated and that gadolinium existed as NaGd9Si6O26, as expected from the literature, or Gd2O3 in the products.

Employing corn derived products to reduce the corrosivity of pavement deicing materials

The goal of this study is to reduce the corrosivity of traditional pavement deicers by employing environmentally safe and low-cost corn-derived polyols namely sorbitol, mannitol, and maltitol. The corrosion inhibition performance of polyols-mixed deicers is investigated for ASTM A572 Gr. 50 high strength low alloy steels. For this purpose, each polyol is added to the traditional deicer (23.0% wt. sodium chloride brine) in the following weight concentrations: 0.5%, 1.0%, 2.0% and 3.0%. The corrosion behavior of ASTM A572 Gr. 50 high strength low alloy steel is then quantified by conducting potentiodynamic polarization tests in the absence and presence of different polyols concentrations in the deicing solution. In addition to the polarization tests, accelerated corrosion tests are performed by continuously subjecting ASTM A572 Gr. 50 steel specimens to the periodic flow of polyols-based deicers in a hot and humid environment inside an environmental chamber to visually monitor the corrosion damage in steel specimens. The results obtained from both polarization tests and accelerated corrosion tests revealed that the addition of small concentrations of corn-derived polyols in the traditional salt brine deicer leads to substantial corrosion inhibition (up to 92%) in the ASTM A572 Gr. 50 steel used in this study. All three polyols are observed to obey the Langmuir’s adsorption isotherm and inhibit the corrosion in ASTM A572 Gr. 50 steels through physical adsorption on the steel surface. The potentiodynamic polarization test results further indicated the mixed-type corrosion inhibiting nature of polyols-based deicing solutions. (C) 2020 Elsevier Ltd. All rights reserved.

Soybean CHX-type ion transport protein GmSALT3 confers leaf Na+ exclusion via a root derived mechanism, and Cl- exclusion via a shoot derived process

Soybean (Glycine max) yields are threatened by multiple stresses including soil salinity. GmSALT3 (a cation-proton exchanger protein) confers net shoot exclusion for both Na+ and Cl- and improves salt tolerance of soybean; however, how the ER-localized GmSALT3 achieves this is unknown. Here, GmSALT3’s function was investigated in heterologous systems and near isogenic lines that contained the full-length GmSALT3 (NIL-T; salt-tolerant) or a truncated transcript Gmsalt3 (NIL-S; salt-sensitive). GmSALT3 restored growth of K+-uptake-defective Escherichia coli and contributed towards net influx and accumulation of Na+, K+ and Cl- in Xenopus laevis oocytes, while Gmsalt3 was non-functional. Time-course analysis of NILs confirmed shoot Cl- exclusion occurs distinctly from Na+ exclusion. Grafting showed that shoot Na+ exclusion occurs via a root xylem-based mechanism; in contrast, NIL-T plants exhibited significantly greater Cl- content in both the stem xylem and phloem sap compared to NIL-S, indicating that shoot Cl- exclusion likely depends upon novel phloem-based Cl- recirculation. NIL-T shoots grafted on NIL-S roots contained low shoot Cl-, which confirmed that Cl- recirculation is dependent on the presence of GmSALT3 in shoots. Overall, these findings provide new insights on GmSALT3’s impact on salinity tolerance and reveal a novel mechanism for shoot Cl- exclusion in plants.

Study on the effect of chloride ion ingress on the pore structure of the attached mortar of recycled concrete coarse aggregate

In this study, based on the porous interface of recycled aggregates (RA), the effects of chloride ion (Cl) ingress by drying-wetting cycles on the pore structure of recycled aggregate concrete (RAC) with a full replacement ratio under different temperatures conditions were investigated. Changes in the pore structure of the old and new mortars were determined by mercury intrusion testing. The surface morphology and morphological characteristics of the reaction products in the pores were observed via scanning electron microscopy. The results showed that the porosity, pore connectivity, fractal dimension and distribution of the pore size and pore volume were remarkably transformed by Cl ingress. During the wetting phase, the products dissolved and migrated between the pores and crystallized during the drying phase, and the increase in temperature promoted this process. With the dry-wet cycles, the original pore space was gradually divided and filled, forming a large number of new pores with smaller pore sizes. The model of RA partition-interface Cl ingress was presented based on the RA porous interface, and the mechanism of the effect of Cl ingress by drying-wetting cycles on the pore structure of RAC was in-depth analyzed.

The volatilization of heavy metals during combustion of polyvinyl chloride after hydrothermal carbonization

This paper experimentally investigated the volatilization characteristic of five heavy metals (cadmium, chromium, nickel, lead and zinc) during combustion of hydrochars of polyvinyl chloride with hydrothermal carbonization pretreatment. The differences of volatilization rate of cadmium and lead between polyvinyl chloride and hydrochars were within 5%, indicating that hydrothermal carbonization had no significant effects on their volatilization behavior. Higher hydrothermal carbonization temperature and lower combustion temperature resulted in lower volatilization rate of zinc. For chromium and nickel, although their volatilization rates were lowered, the absolute volatilization rates increased remarkably because of the increase of original concentrations. Nevertheless, the total emissions of heavy metals studied reduced. Hydrothermal carbonization performed at 230 degrees C showed the most significant absolute volatilization rates reductions ranged from 79.2% to 86.8% depending on combustion temperature. The highest concentrations of chromium and nickel in bottom ash reached up to 20.1 g/kg and 7.9 g/kg, respectively. (C) 2020 Elsevier Ltd. All rights reserved.

Alternative methods of viability determination in single cell mass cytometry

The identification and discrimination of viable cells is important to understand how experimental variables may influence biochemical processes such as cell metabolism, cell cycle, and signaling pathways. Cisplatin is commonly used as a viability stain in mass cytometry studies, however, recent work by Mei et al. has demonstrated that cisplatin can also be used to label antibodies, complicating the simultaneous use of the platinum measurement channels for both antibody and viability staining. This study demonstrates that other metal salts (hafnium chloride, niobium chloride, and zirconium chloride) can serve as substitutes for cisplatin in viability staining. These stains yield similar fractions of live and dead cells and stain the same dead cells in parallel high parameter analyses. In addition, this study demonstrates how a variety of protein antigen viability markers (pRb, Ki-67, Histone H1, cleaved PARP, and GAPDH) can be used to discriminate live and dead cell populations, without the need for a separate viability staining step. As few as two of these protein antigen viability markers can help identify live and dead cell populations in fixed samples and can identify the same viable cells in high dimensional analyses with or without use of viability stain information. This study demonstrates several alternative approaches to mass cytometry viability assessment that can facilitate use of platinum isotopes for antibody staining and enables identification of live and dead cell populations in samples for which a separate viability stain is not practical.
