Upon CNCs content exceeding 10 wt%, the mechanical behavior of the material exhibits a yield point that resembles those observed in plastics. Taking into account the influence of filler content of CNCs and thickness, the three-dimensional orientation degree of NR crystallites can be quantitatively assessed. The formation of 3D NR crystallites can be established when the CNCs content surpasses 10%, and concurrently, the degree of three-dimensional orientation of crystallites increases as thickness decreases. It was found that not only do CNCs enhance the confinement effect, leading to a decrease in the onset strain, but it is also beneficial for the formation of 3D-oriented strain-induced NR crystallites. The current study not only helps to a comprehensive understanding of the mechanism of 3D-oriented strain-induced NR crystallites by the constrained rigid filler network, but also provides the potential application of uniaxial tensile stretching in creating 3D functional materials.","PeriodicalId":70,"journal":{"name":"CrystEngComm","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141587272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elemental analyses revealed the multilayer structure consisting of Ni3S2, NiS, and Fe. The Ni3S2-Fe-Ni catalyst exhibited impressive electrochemical performance due to optimization of its structure with the overpotential of HER and OER of only 83 and 190 mV.

The catalysis performance remained nearly unchanged after 48 h of stability testing.

Out of 28 combinations, 19 experiments yielded crystals suitable for single-crystal X-ray diffraction. Structural analysis revealed that in all of the obtained cocrystals the most prominent supramolecular interaction is the I···Noxazole halogen bond with relative shortening values of up to 18 %, comparable to I···Npyridine halogen bond shortening values. The acceptors are ditopic in 10 cocrystals and form additional I···N, I···O or I··· π halogen bonds. A majority of cocrystals feature one donor molecule per one acceptor molecule. In order to rank the acceptor sites and establish how the electrostatic potential differences impact the supramolecular landscape around these molecules, the values of molecular electrostatic potentials (MEPs) were calculated on their optimized geometries. These calculations were in agreement with experimental observations, since the best (most negative MEP value) acceptor binding site in the series of used oxazoles is the oxazole nitrogen atom. Depending on the difference between MEP values of the oxazole oxygen atom and the peripheral functionalities, additional halogen bonds could potentially be formed with one of these acceptor sites, leading to the formation of two different types of halogen-bonded supramolecular chains.","PeriodicalId":70,"journal":{"name":"CrystEngComm","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141570174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solid-state analysis reveals the contrasting crystal chemistry with the strongest synthon involving hydrogen bonding synthons and π – π van der Waals interactions for forms I and II, respectively. Analysis of the molecular conformational energies reveals the molecular structures for forms I and II to be very close which is matched by their calculated lattice energies. Crystallisation as a function of both solute concentration and solution cooling rate reveals form II to be mostly more preferred than form I. The higher stability of the form II conformer together with its easier conformational adjustment during the formation of form II crystals, is consistent with its greater crystallisability compared to the more stable form I. Solute concentration analysis of the relative stabilities of the two forms as a function of their sizes reveals that smaller cluster sizes, are required to stabilise the crystal structure for form I with respect to form II. Polymorphic screening as a function of solvent confirms the predicted poor crystallisability of form I whose crystallisation is preferred at higher initial solute concentrations and lower cooling rates in polar solvents but less so for the more apolar solvent toluene, the latter being consistent with π – π solute/solvent interactions promoting the formation of hydrogen bonded solute/solute synthons at the expense of π – π interactions. Modelling work correlates well with the observed crystallisation behaviour, highlighting the importance of understanding solvent selection and solution state structure at the molecular-scale level for directing polymorphic outcomes as confirmed by the higher crystallisability of the metastable form II.","PeriodicalId":70,"journal":{"name":"CrystEngComm","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141570385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interestingly, N3 participates in binding with Cd2+ and Hg2+ ions, resulting in the formation of a 1-D linear coordination polymer bridged by chloride anions. The observed polymeric structure exhibits further extension through intermolecular non-classical hydrogen bonding and − stacking interactions. In contrast, Zn2+ forms discrete coordination complexes that extend in the lattice due to hydrogen bonding interactions.
