Opportunities for mobilizing recalcitrant phosphorus from agricultural soils: a review.

Plant Soil 2018 1;427(1):5-16. Epub 2017 Aug 1.

1Lancaster Environment Centre, Lancaster University, Lancaster, LA1 4YQ UK.

Background: Phosphorus (P) fertilizer is usually applied in excess of plant requirement and accumulates in soils due to its strong adsorption, rapid precipitation and immobilisation into unavailable forms including organic moieties. As soils are complex and diverse chemical, biochemical and biological systems, strategies to access recalcitrant soil P are often inefficient, case specific and inconsistently applicable in different soils. Finding a near-universal or at least widely applicable solution to the inefficiency in agricultural P use by plants is an important unsolved problem that has been under investigation for more than half a century.

Ligand induced structure and property changes of 1T-MoS.

Phys Chem Chem Phys 2019 Apr 18. Epub 2019 Apr 18.

Frontier Institute of Science and Technology, Xi'an Jiaotong University, Xi'an 710054, China.

Stabilizing metastable 1T-MoS2 sheets is significant for their potential applications. In this work, we investigate the influence of surface adsorption of a series of functional groups (including -H, -O, -SH, -NH2, -CH3, -CF3, -SCH3 and -OCH3) on the structural and electronic properties of 1T-MoS2 by using first-principles calculations. Strong adsorptions of these functional groups eventually transform 1T-related MoS2 monolayers into the 1T' phase (featuring zigzag Mo-Mo chains). Read More

Flux melting of metal-organic frameworks.

Chem Sci 2019 Mar 12;10(12):3592-3601. Epub 2019 Feb 12.

Department of Materials Science and Metallurgy , University of Cambridge , Charles Babbage Road , Cambridge , CB3 0FS , UK . Email:

Recent demonstrations of melting in the metal-organic framework (MOF) family have created interest in the interfacial domain between inorganic glasses and amorphous organic polymers. The chemical and physical behaviour of porous hybrid liquids and glasses is of particular interest, though opportunities are limited by the inaccessible melting temperatures of many MOFs. Here, we show that the processing technique of flux melting, 'borrowed' from the inorganic domain, may be applied in order to melt ZIF-8, a material which does not possess an accessible liquid state in the pure form.

Materials (Basel) 2019 Apr 16;12(8). Epub 2019 Apr 16.

Institut de Science des Matériaux de Mulhouse (IS2M) UMR 7361, Université de Haute-Alsace, CNRS, F-68100 Mulhouse, France.

Transition metal hexacyanoferrate/microporous activated carbon composites were obtained using a simple successive impregnation approach. The effect of metal type (nickel, indium, or copper), and the carbon oxidation on the composite characteristics (porosity, metal structure, and particle size), as well as on the removal efficiency of cesium from aqueous solution was investigated. Successful formation of the desired metal hexacyanoferrate phase was achieved and the size of the metallic nanoparticles and their dispersion in the carbon network was found to depend on the metal type, with the indium and nickel-based materials exhibiting the smallest particle size distribution (< 10 nm).

Phys Chem Chem Phys 2019 Apr 17. Epub 2019 Apr 17.

Department of Applied Chemistry, Graduate School of Urban Environmental Sciences, Tokyo Metropolitan University, 1-1 Minami-osawa, Hachioji, Tokyo 192-0397, Japan.

How can radioactive Cs+ ions be removed from aqueous solution? From this perspective, the adsorption of Cs+ was investigated by using five types of clay minerals possessing different charge exchange capacities. The fixation ability for Cs+ depended on the charge exchange capacity of the clay minerals. Phlogopite and vermiculite, where the number of charges is almost equal to half the number of siloxane ditrigonal cavities in the structure, exhibited a strong Cs+ fixation ability among these clay minerals.

Alternatives to Cryogenic Distillation: Advanced Porous Materials in Adsorptive Light Olefin/Paraffin Separations.

Small 2019 Apr 17:e1900058. Epub 2019 Apr 17.

Department of Chemical and Biomolecular Engineering, National University of Singapore, 4 Engineering Drive 4, Singapore, 117585, Singapore.

As primary feedstocks in the petrochemical industry, light olefins such as ethylene and propylene are mainly obtained from steam cracking of naphtha and short chain alkanes (ethane and propane). Due to their similar physical properties, the separations of olefins and paraffins-pivotal processes to meet the olefin purity requirement of downstream processing-are typically performed by highly energy-intensive cryogenic distillation at low temperatures and high pressures. To reduce the energy input and save costs, adsorptive olefin/paraffin separations have been proposed as promising techniques to complement or even replace cryogenic distillation, and growing efforts have been devoted to developing advanced adsorbents to fulfill this challenging task.

Triple-Layered Carbon-SiO Composite Membrane for High Energy Density and Long Cycling Li-S Batteries.

ACS Nano 2019 Apr 19. Epub 2019 Apr 19.

Materials Science and Engineering Program and Department of Mechanical Engineering , The University of Texas at Austin , Austin , Texas 78712 , United States.

Here we report a highly scalable yet flexible triple-layer structured porous C/SiO membrane via a facile phase inversion method for advancing Li-sulfur battery technology. As a multifunctional current-collector-free cathode, the conductive dense layer of the C/SiO membrane offers hierarchical macropores as an ideal sulfur host to alleviate the volume expansion of sulfur species and facilitate ion/electrolyte transport for fast kinetics, as well as spongelike pores to enable high sulfur loading. The triple-layer structured membrane cathode enables the filling of most sulfur species in the macropores and additional loading of a thin sulfur slurry on the membrane surface, which facilitates ion/electrolyte transport with faster kinetics than the conventional S/C slurry-based cathode.

Sci Rep 2019 Apr 15;9(1):6101. Epub 2019 Apr 15.

Department of Immunobiology, Yale University School of Medicine, 300 Cedar Street, New Haven, CT, 06519, USA.

PMEL is a pigment cell-specific protein that forms a functional amyloid matrix in melanosomes. The matrix consists of well-separated fibrillar sheets on which the pigment melanin is deposited. Using electron tomography, we demonstrate that this sheet architecture is governed by the PMEL repeat (RPT) domain, which associates with the amyloid as an accessory proteolytic fragment. Read More

CO oxidation over the polyoxometalate-supported single-atom catalysts M/POM (Fe, Co, Mn, Ru, Rh, Os, Ir, and Pt; POM = [PWO]): a computational study on the activation of surface oxygen species.

Dalton Trans 2019 Apr 15. Epub 2019 Apr 15.

College of Chemical Engineering, Northeast Electric Power University, Jilin City, 132012, P. R. China.

The discrete anionic structure of polyoxometalates (POMs) at the interface is more like a separate small "island", which effectively prevents the diffusion of single atoms and prohibits the agglomeration and generation of metal particles; thus, POMs can enhance the sintering-resistant behavior and increase metal loading on the surface of single-atom catalysts (SACs). To explore the catalytic performance of POM-supported SACs for CO oxidation, we employed density functional theory (DFT) calculations to gain an understanding of some important aspects, including the CO adsorption, the formation of oxygen vacancies, and the activity of the surface oxygen species, of the catalytic system. Compared to previous theoretical studies, in which the catalytic behavior of POMs has been investigated based on the anionic unit with the highest negative charge, herein, we have constructed a model of the POM-supported SACs, which are neutral species.

Pore size effect on the separation of polymers by interaction chromatography. A Monte Carlo study.

Anal Chim Acta 2019 Aug 12;1064:126-137. Epub 2019 Mar 12.

Department of Physical and Macromolecular Chemistry, Faculty of Science, Charles University, Hlavova 8, 128 00, Praha 2, Czech Republic. Electronic address:

When the polymers are studied by interaction chromatography (IC) in porous media, the IC separation mechanism competes with the size-exclusion chromatography (SEC) mechanism and under specific conditions close to the critical adsorption point (CAP), the elution times of monodisperse polymer samples nonmonotonically depend on pore sizes. We performed Monte Carlo (MC) simulations to elucidate this intriguing effect. By analyzing the behavior of self-avoiding and intersecting chains in two-dimensionally (2D)-confining square pores and in 1D-confining slits in good and Θ-solvents, we confirmed that the dimensionality of the confinement, more specifically, pore geometry, controls the chromatographic behavior.
