Non-Hermitian topological phases exhibit a number of exotic features that have no Hermitian counterparts, including the skin effect and breakdown conventional bulk-boundary correspondence. Here, we implement non-Hermitian Su-Schrieffer-Heeger (SSH) Hamiltonian, which is prototypical model for studying phases, with solid-state quantum simulator consisting an electron spin $^{13}$C nuclear in nitrogen-vacancy (NV) center diamond. By employing dilation method, realize desired non-unitary...
Severe CO2 emissions has posed an increasingly alarming threat, motivating the development of efficient capture materials, one key parts carbon capture, utilization, and storage (CCUS). In this study, a series metal–organic frameworks (MOFs) named Sc-X (X = S, M, L) were constructed inspired by recorded MOFs, Zn-BPZ-SA MFU-4l-Li. The corresponding isoreticular double-interpenetrating MOFs (Sc-X-IDI) subsequently via introduction double interpenetration. Grand canonical Monte Carlo (GCMC)...
Covalent organic frameworks (COFs) have become potential candidates for gas purification technology, especially in carbon capture and storage applications. By utilizing strategies such as pore structure design functional modification, COFs been developed to exhibit high selectivity superior adsorption capacity the effective separation of CO2 from industrial waste gases. Notably, alkali metals strong interactions with backbone COFs, which can enhance CO2/N2 performance these porous materials....
A gold-catalyzed synthesis of tetrasubstituted 1,3-enynes from hypervalent iodine(III) reagents and activated alkenes is reported. This reaction involves an in situ formed alkynyl Au(III) species a subsequent direct C(sp2)–H functionalization alkenes, offering 26 enynes 62–92% yield with excellent functional group tolerance.
Birefringent crystals can modulate and detect the polarization of light are important optical functional materials. The birefringence is positively correlated to anisotropy structure. By partially substituting sulfate anion with large electronegative fluorine in parent compound Y2(SO4)3·8H2O, a new fluorinated rare-earth YSO4F·H2O enhanced was achieved. features dense 3D structure constructed by polarizable [YOF] polyhedra [SO4] tetrahedra. diffuse reflectance spectrum reveals that it has...
There are two molecules in the asymmetric unit of title compound, C10H12N2O3, with almost identical conformations. The crystal structure is stabilized by intermolecular N—H⋯O hydrogen bonds.
meso and rac isomers of (η5:η5-C5H4RMeSiSiMeRC5H4)Fe2(CO)2(μ-CO)2 (R = Ph, n-Bu) were synthesized successfully separated for the first time. They found to undergo title rearrangement reaction in a nonstereospecific fashion, give products [RMeSi-η5-C5H4Fe(CO)2]2 as mixtures ratios about 1:1. This is direct evidence rule out concerted free radical mechanism that currently used explain this reaction. A new involving activation Si−Si bond by coordinatively unsaturated iron center suggested.
Crude oil is one of the most important energy sources in world and contains a lot paraffin wax. At higher temperatures, wax dissolved crude an equilibrium state. However, when temperature lower than precipitation wax, will precipitate, crystallize, form three-dimensional network structure, which have great impact on transportation oil. In engineering, waxy usually transported by adding pour point depressants. Pour depressant molecules can significantly improve crystallization behavior This...
Steam flooding is an effective development method for heavy oil reservoirs, and the steam assisted by profile control system can plug dominant channels further improve recovery factor. High-temperature-resistant foam as a hot research topic, key lies in optimal design of system. In this paper, lignin was modified sulfonation to obtain high-temperature-resistant named CRF; foaming agent CX-5 confirmed have good high-temperature ability reducing surface tension; formula (A compound CRF CX-5,...

Abstract Seawater electrolysis is an effective way for large‐scale green hydrogen. Nevertheless, the anode suffers from severe corrosion of Cl − and Br during oxygen evolution, which gives rise to issues narrow‐deep pits shallow‐wide pits, respectively. Herein, anti‐corrosion strategy presented by self‐adapting oxyanion armor prevent high valence active sites corrosion. The core–shell FeNi 2 Se 4 @NiFe‐Phy reconstructed species NiFeOOH covered layer composed phosphoric carbonate. aimed...
Carbon nanotubes (CNTs), as a new type of carbon material with complete molecular structure, have great application potential in the field nanocomposites. In this study, were first surface modified to give them good hydrophilicity. Subsequently, nanocomposite coagulant (PASS-T) different CNTs (m-CNTs) contents was prepared by alkaline titration method. The CNT, m-CNT, PASS and PASS-T characterized FTIR, XRD XRF. Then applied oily sewage, coagulation results showed that (0.1%) had best oil...
