Ion diffusion property prediction of cementitious materials by modeling pore structure is a hotspot and challenge for cement and concrete research. In a recent paper, Yio et al. examined the 3D structure of cap-illary pores (>0.24 lm) within 1003 lm3 blended cement paste for the first time using laser scanning con focal microscopy (LSCM). The main advantage of LSCM is the ability to characterize the 3D structure of interconnected pores and then to improve the possibility of establishing more effective pore structure models. This contribution proposes a novel and concise pore structure model named accessible cylindrical tortuous pore model (ACTPore model) for describing the physical connections among accessible porosity, mean pore diameter, tortuosity and pore specific surface area. The ACTPore model is proved to be rational and verified by LSCM experimental results. (C) 2020 Elsevier Ltd. All rights reserved.

Cellulose is a renewable, biodegradable, biocompatible, and sustainable material. A bamboo cellulose-based nanofiltration membrane (LBL-NF-CS/BCM) was prepared with a combination of layer-by-layer assembly and spraying methods. The chemical structure, morphology, and surface charge of the resultant LBL-NF-CS/BCM composite membranes were characterized based on Thermo Gravimetric Analysis (TGA), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and X-ray Photoelectron Spectroscopy Scanning (XPS). The nanofiltration performance of the LBL-NF-CS/BCM composite membranes was evaluated using 500 ppm NaCl solutions under 0.3 MPa pressure. It was found that the LBL-NF-CS/BCM composite membranes had a rejection rate of about 36.11 % against a 500 ppm NaCl solution under the conditions tested, and membrane flux of about 12.08 L/(m(2) h) was reached. The combined layer-by-layer assembly and spraying provides a scalable and convenient process concept for nanofiltration membrane fabrication.

The inhibition efficiency of N- and/or O-containing compounds for the corrosion of metals and alloys in aggressive media is an essential theme. For this purpose, a newly synthesized and fully characterized multidentate ligand, N,N’-((ethane-1,2-diylbis(azanediyl))bis(ethane-2,1-diyl))bis(quinoline-2-carboxamide) (QATETA), derived from quinaldic acid and triethylenetetramine (TETA) was examined gravimetrically and electrochemically as an inhibitor for the corrosion for mild steel in aqueous sodium chloride (3.5 %). Moreover, the reactivity and efficiency of QATETA were also theoretically investigated using density functional theory and Monte Carlo simulations methods. The results indicate that the corrosion inhibition of QATETA was concentration-dependent. In addition, QATETA was categorized as a mixed type inhibitor. Thermodynamic calculations confirmed that the adsorption of QATETA on the metal surface is a spontaneous process obeying Langmuir adsorption isotherm. Furthermore, computational simulations have corroborated the experimental results. Both physical and chemical adsorption mechanisms are suggested.

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.

Recent advances in chemical admixtures for improving the workability of alkali-activated slag-based material systems

The early reaction process of alkali-activated slag (AAS) systems is much faster than that of Portland cement systems, resulting in rapid setting. Therefore, fluidity control and setting adjustment are two critical issues for practical applications of AAS; these issues are usually addressed using chemical admixtures. This paper reviews the current research progress in the field of chemical admixtures to improve the workability and setting time of AAS systems. The stability of different superplasticizers, including vinyl copolymers (V), melamine (M), lignosulfonate (LS), naphthalene (N) and polycarboxylate (PCE), in different alkaline activator solutions is summarized and is important in terms of their dispersion performance in AAS systems. The nature of alkaline activators has a significant influence on the performance of the polymers. Moreover, the effects of different superplasticizers and retarders on the workability, setting time and mechanical properties of the AAS systems are discussed. This review provides guidance for improving the AAS performance by superplasticizers and retarders to promote the application of AAS in construction engineering. (C) 2020 Elsevier Ltd.

Effects of N deposition on the quality and quantity of soil organic matter in a boreal forest: Contrasting roles of ammonium and nitrate

Elevated nitrogen (N) deposition plays a critical role in soil organic matter (SOM) transformation, but the responses of the quantity and quality of SOM to ammonium and nitrate fertilization remain unclear. In this work, a 6-year field experiment amended with ammonium chloride (NH4Cl) and potassium nitrate (KNO3) fertilizers at four rates of 0, 10, 20, and 40 kg N ha(-1) yr(-1) was conducted in a boreal forest. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) analysis and elemental analysis were used to investigate the chemical composition and soil organic carbon (SOC) contents in bulk soils and two density fractions (light fraction < 1.70 g cm(-3) and heavy fraction > 1.70 g cm(-3)). Soil microbial community composition was determined based on phospholipid fatty acids (PLFAs) analysis. Results showed that the SOC contents in the organic and mineral layers under nitrate addition were significantly increased by 27-87%. By contrast, ammonium addition significantly decreased the SOC contents in the organic layer by 28-54%. Nitrate addition increased relative proportions of acetic acid in the light fraction and toluene in bulk soil, but decreased relative abundance of phenol in bulk soil, indicating that more plant-derived input contributed to the increase of SOC. Contrastingly, ammonium addition increased the proportions of benzene in bulk soil and pyrrole as well as the mineralization index (pyrrole/phenol) in the heavy fraction, suggesting more advanced mineralization degree of SOM. Moreover, ammonium addition altered microbial community structure with a higher ratio of fungi/bacteria (F/B) while nitrate addition had little effect on soil microbial community. Overall, our findings highlight the contrasting roles of ammonium and nitrate in SOM dynamics, which should be distinguished to accurately predict the responses of SOC sequestration to N deposition especially in N-limited boreal forests.

Electrodeposition of Pd alloys from choline chloride/urea deep eutectic solvents

In this study, the electrodeposition of palladium alloys was investigated in a choline chloride/urea based deep eutectic solvent containing sulfosalicylic acid dihydrate as organic additive and Pd(II) + Ag(I), Pd(II) + Pt (II), or Pd(II) + Pt (II) + Ag(I) as metal components. The electrochemical behavior of the electrolytes was characterised by cyclic voltammetry. The electrodeposition processes require nucleation overpotential. Energy-dispersive X-ray data indicated that the layer thickness and composition of the produced Pd-Ag, Pd-Pt, and Pd-Pt-Ag films could be varied by changing the deposition mode. Additions of Ag(I) to the Pd and Pd-Pt electrolytes enhanced the overall metal deposition rate. Scanning electron micrographs of the electrodeposits showed that in general, the Pd alloys deposited by pulse current were nodular and relatively compact, whereas the films deposited by potentiostatic deposition were less dense and covered with dendrite-like and sharp-edged crystallites. Data collected from X-ray diffraction (XRD) experiments proved the existence of metallic alloys. (C) 2020 Elsevier B.V. All rights reserved.

Facile and sustainable fabrication of high-performance cellulose sponge from cotton for oil-in-water emulsion separation

Given complexity and diversity of oily wastewater, developing highly efficient separation materials through green and facile strategy are urgently needed. Herein, a smart strategy is demonstrated to transform raw cotton into uniform cellulose sponge for separation oil-in-water emulsion. The raw cotton is directly treated in zinc chloride aqueous solutions through a controllable dissolution process. After regeneration without any further chemical modification and freeze drying, the evolved cellulose sponge, which is composed of partially dissolved cotton fiber and exfoliated regenerated cellulose, exhibits interesting three-dimensional (3D) interconnected hierarchical porous network structure and stable wettability of superoleophobicity (theta(oil) > 150 degrees) under water. Cellulose sponge has excellent underwater superoleophobicity and antifouling property due to the natural hydrophilicity of cellulose. Based on the beneficial 3D hierarchical structure and superwettability, the cellulose sponge can separate highly emulsified oil-in-water emulsions with efficiency up to 99.2% solely under the driving of gravity. Our strategy provides a generic way to convert cellulose-based materials into cellulose porous materials with excellent permeability, separation efficiency, antifouling, and reusability property for oil/water emulsions separation. This economical, environmentally friendly and functional cellulose sponge not only allows natural cotton resources to be used rationally with high value-added, but also effectively solves the problems of oily wastewater.Y

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.
