Swelling‐induced Mechanochromism in Multinetwork Polymers
Authors: Watabe Takuma , Otsuka Hideyuki 
Published: December 2022

AbstractWe report a novel and versatile approach to achieving swelling‐induced mechanochemistry using a multinetwork (MN) strategy that enables polymer networks to repeatedly swell with monomers and solvents. The isotropic expansion of the first network (FN) provides sufficient force to drive the mechanochemical scission of a radical‐based mechanophore, difluorenylsuccinonitrile (DFSN). Although prompt recombination generally occurs in such highly mobile environments, the resulting pink radicals are kinetically stabilized in the gels, probably due to limited diffusion in the extended polymer chains. Moreover, the DFSN embedded in the isotropically strained chain exhibits increased thermal reactivity, which can be reasonably explained by an entropic contribution of the FN to the dissociation. The utility of the MN polymers is demonstrated not only in terms of swelling‐force‐induced network modification, but also in the context of tunable reactivity of the dissociative unit through proper design of the hierarchical network architecture.

AbstractSelf‐assembly FeII complexes of phenazine (Phen), quinoxaline (Qxn), and 4,4′‐trimethylenedipyridine (Tmp) with tetrahedral building blocks of [HgII(XCN)4]2− (X=S or Se) formed six new high‐dimensional frameworks with the general formula of [Fe(L)m][Hg(XCN)4]⋅solvents (L=Phen, m/X=2/S, 1; L=Qxn, m/X=2/S, 2; L=Qxn, m/X=1/S, 3; L=Qxn, m/X=1/Se, 3‐Se; L=Tmp, m/X=1/S, 4; and L=Tmp, m/X=1/Se, 4‐Se). 1, 3, and 3‐Se show an intense sub‐terahertz (sub‐THz) absorbance of around 0.60 THz due to vibrations of the solvent molecules coordinated to the FeII ions and crystallization organic molecules. In addition, crystals of 1, 4, and 4‐Se display low‐frequency Raman scattering with exceptionally low values of 0.44, 0.51, and 0.53 THz, respectively. These results indicate that heavy metal FeII−HgII systems are promising platforms to construct sub‐THz absorbers.

Published: December 2022

AbstractModels for the calculation of density, heat capacity, viscosity, and thermal conductivity of amino acid aqueous solutions were proposed. Density, heat capacity, viscosity, and thermal conductivity of pure amino acid liquids were predicted by the Rackett model, Watson model, Heu‐Sheu‐Tu group contribution method, and Sato‐Riedel model, respectively. Mixing rule equations required for the prediction of density, heat capacity, viscosity, and thermal conductivity of amino acid aqueous solutions were suggested. Density, heat capacity, viscosity, and thermal conductivity data of 930, 975, 450, and 167 data points, respectively, for 20 amino acid aqueous solution systems were regressed to determine the most appropriate mixing rule parameters.
Electrochemical Behaviour of Organic Explosive Compounds in Ionic Liquids: Towards Discriminate Electrochemical Sensing
Authors: Hay Catherine E. , Linden Sarah K. , Silvester Debbie S. 
Published: December 2022

AbstractThe electrochemical reduction of four organic explosive compounds, 1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocane (HMX), 1,3,5‐trinitro‐1,3,5‐triazinane (RDX), pentaerythritol tetranitrate (PETN) and 2,4,6‐trinitrophenylmethylnitramine (tetryl), is studied in eight room temperature ionic liquids (RTILs). In all RTILs, the reduction peaks were highly complicated, but much better resolved than in previous studies in conventional solvents. HMX typically showed broad overlapping peaks in RTILs with distinctly different voltammetric wave shapes. The voltammetry of RDX also varied dramatically, ranging from one to four reductive peaks with broad features. PETN showed one large reduction peak owing to the overlapping reduction processes for all the nitro‐ groups. Tetryl produced the most complex voltammetry with the largest number of cathodic peaks, likely due to the structure that contains both nitramine and nitroaromatic groups. For all explosives, an electrogenerated product was oxidized on the reverse scan. The reduction potentials and voltammetric wave shapes were found to vary significantly in the different RTILs, allowing the possibility to ‘fingerprint’ the different explosives using their distinct signatures, suggesting that discriminative sensing may be possible by careful tuning of the RTIL structure. Exploring the electrochemical behaviour of these explosives is a first step towards utilising RTILs as favourable solvents for the electrochemical detection of such compounds.

Published: December 2022

AbstractAll‐solid‐state batteries (ASSBs) are considered the most promising next‐generation energy storage device owing to their high safety. The sulfide solid electrolytes (SEs) possess high ionic conductivity (10−4–10−2 S cm−1) at room temperature, non‐flammable properties, and moderate modulus, all of which are crucial requirements for the scalable application of high‐performance ASSBs. However, achieving a high energy density of >300 Wh kg−1 appears to be a significant hurdle in current ASSBs. Research on high‐energy‐density anode materials is of great importance for enhancing the overall energy density in ASSBs. However, relatively few review articles have focused on the overall development profile of representative anode materials in sulfide SEs. Here, we start by underlining the importance of the multi‐physical properties of sulfide SEs, including ionic conductivity, chemical properties, and mechanical properties. Furthermore, the potential failure mechanisms of sulfide SEs with Li anodes and corresponding improvement strategies are systematically discussed. Finally, we summarize recent notable works of anode materials in sulfide‐based ASSBs, aiming to provide important guidance for fulfilling a real leap of high energy density anode materials in sulfide ASSBs.

Published: December 2022

AbstractIt is particularly significant to apply stable and low‐cost catalysts in electrochemical water oxidation. It has been reported that molybdenum carbides have exceptional water dissociation ability in thermal catalysis. However, its role in electrocatalytic water oxidation, in which water dissociation is the key initial step, has not yet been paid attention to. Herein, cobalt oxide (CoOx) nanoparticles, by an incipient‐wetness impregnation method, were successfully supported on the surface of nitrogen‐doped porous carbon homogeneously distributed ultrafine α‐MoC nanoparticles with nitrogen‐doped porous carbon (α‐MoC/NC) and worked as efficient electrocatalysts for water oxidation. By regulating the loading amounts of cobalt oxide and the calcination temperature, a series of mesoporous CoOx@α‐MoC/NC composites were obtained. The optimal electrocatalyst exhibited low oxygen evolution overpotential (10 mA cm−2, 410 mV) and an excellent anodic stability. Experimental results implied that the synergistic effect between cobalt oxide and α‐MoC/NC can facilitate water oxidation, with the latter having the ability to dissociate water molecules.

AbstractElectrochemical CO2 reduction is an environmentally sustainable way for CO2 conversion and utilization, the development of which needs highly efficient catalysts. Ag‐based materials are one kind of electrocatalyst that are catalytically active for CO2 reduction to CO. In this work, Ag clusters were fabricated on nitrogen‐doped porous carbon nanomaterials by a high‐temperature annealing method. The well‐dispersion of Ag sites on nitrogen‐doped carbons (Ag/NC) promoted CO production. As a result, Ag/NC showed a maximum Faradaic efficiency of 94 % at −0.7 V versus reversible hydrogen electrode (vs RHE) at room temperature. In addition, Ag/NC showed good CO2 reduction stability, and the CO Faradaic efficiency remained stable at about 90 % at −0.7 V vs RHE for 12 h. Density functional theory calculation indicated that the cooperation of Ag and N‐dopings effectively reduced the activation energy barrier of CO2 reduction relative to hydrogen evolution reaction and thus effectively promoted the electrocatalytic reduction of CO2 molecules to CO. This method provides a new idea for the synthesis of CO2 reduction catalysts with higher activity, selectivity and stability.
Paramagnetic Liquid Crystals With Close π–π Packing: The Effect of Blatter Radical Planarization on Behavior of Bent‐Core Mesogens

Published: December 2022

AbstractA new, 19 π‐delocalized electrons planar Blatter radical building block was developed and used to obtain paramagnetic bent‐core liquid crystals. The mesogens were investigated by optical, thermal, powder XRD and DFT methods in the pure form and as binary mixtures. Comparison of their properties with those of the classical Blatter radical analogues revealed that planarization of the central angular element results in a significantly higher stability of the mesophases and increased molecular organization suitable for the formation of ordered banana and columnar mesophases with tighter π–π interactions. These results indicate access to a new, potentially rich class of functional paramagnetic soft materials.

Published: December 2022

AbstractIn the chalcogen series, tellurium species exhibit the strongest chalcogen bonding (ChB) interaction with electron‐rich atom. This property explains the renewed interested toward tellurium‐based derivatives and their use in different applications, such as organocatalysis. In this context, the catalytic activity of telluronium salts in the Povarov reaction is presented herein. Different dienophiles, as well as imines of variable electronic nature, efficiently react in the presence of catalytic amount of either diarylmethyltelluronium or triaryltelluronium salts. Both catalysts could also readily perform the three‐component Povarov reaction starting from aldehyde, aniline and dihydrofuran. The reactivity of telluroniums towards imines and aldehydes was confirmed in the solid state by the ability of Te atom to interact through ChB with the oxygen carbonyl of acetone, and in solution with significant shift variations of the imine proton and of the tellurium atom in 1H and 125Te NMR spectroscopy. For the most active telluronium catalysts bearing CF3 groups, association constants (K) with N‐phenyl phenylmethanimine in the range 22–38 M−1 were measured in dichloromethane.

Published: December 2022

AbstractSuppressing the amount of carbon dioxide in the atmosphere is an essential measure toward addressing global warming. Specifically, the photocatalytic CO2 reduction reaction (CRR) is an effective strategy because it affords the conversion of CO2 into useful carbon feedstocks by using sunlight and water. However, the practical application of photocatalyst‐promoting CRR (CRR photocatalysts) requires significant improvement of their conversion efficiency. Accordingly, extensive research is being conducted toward improving semiconductor photocatalysts, as well as cocatalysts that are loaded as active sites on the photocatalysts. In this review, we summarize recent research and development trends in the improvement of cocatalysts, which have a significant impact on the catalytic activity and selectivity of photocatalytic CRR. We expect that the advanced knowledge provided on the improvement of cocatalysts for CRR in this review will serve as a general guideline to accelerate the development of highly efficient CRR photocatalysts.

Published: December 2022

AbstractGreen‐to‐blue triplet–triplet annihilation photon upconversion with the well‐studied upconversion pair 9,10‐diphenylanthracene (DPA)/platinum octaethylporphyrin (PtOEP) was used to reversibly drive the photoisomerization of diarylethene (DAE) photoswitches by using visible light. By carefully selecting the kinetic and spectral properties of the molecular system as well as the experimental geometry, a single green light source can be used to selectively trigger both the ring‐opening and the ring‐closing reactions, whilst also inducing fluorescence from the colored closed isomer that can be used as a readout to monitor the isomerization process in situ. The upconversion solution and the DAE solution are kept physically separated, allowing them to be characterized both concomitantly and individually without further separation processes. The ring‐closing reaction using upconverted photons was quantified and compared to the efficiency of direct isomerization with ultraviolet light.
Heteroaryl‐Substituted Bis‐Anils: Aggregation‐Induced Emission (AIE) Derivatives with Tunable ESIPT Emission Color and pH Sensitivity
Authors: Stoerkler Timothée , Retailleau Pascal , Jacquemin Denis , Ulrich Gilles , Massue Julien 
Published: December 2022

AbstractThe two‐step synthesis, structural, and photophysical properties of a series of heteroaryl‐substituted bis‐anil derivatives presenting aggregation‐induced emission (AIE) coupled with an excited‐state intramolecular proton transfer (ESIPT) process is described. The fluorescence color of the aggregates can be fine tuned by changing the electronic nature of the peripheral substitution, leading to a wide range of emission wavelengths (from green to the near infra‐red). Moreover, upon introduction of strong electron‐withdrawing groups such as cyano (CN), a competition between ESIPT and deprotonation is observed leading to the emission of the anionic species at low water percentage. This observation led to the synthesis of an additional mixed AIE fluorophore, functionalized by methoxy groups on one side and cyano groups on the other side. Upon addition of water, this dye displays first anionic emission, followed by typical AIE/ESIPT red fluorescence upon formation of the aggregates. TD‐DFT calculations on selected AIE dyes were performed to rationalize the nature of the emissive transitions in these derivatives.

Published: December 2022

AbstractIn this work, we assemble amphiphilic iron(III) corroles at air‐water interfaces into well‐defined quasi‐two‐dimensional molecular monolayers and theirs stacks for sensing of nitric oxide (NO). For this purpose, we use the Langmuir‐Blodgett (LB) technique, which allows varying the packing density of iron(III) corroles anchored to the aqueous subphase via one molecular side. The stacks of ten down to three molecular monolayers on the front and back sides of the substrates are sufficiently optically dense to detect NO binding to the layers photometrically. This sensing with few layers demonstrates the potential for electronic detection, where very thin surface functionalizations enable efficient electronic communication between the layer and the (semi)conductor. Despite increasing optical densities, the spectral responses to NO exposure become smaller with increasing packing density until the collapse point of the monolayers is reached. This demonstrates that the highest molecular efficiency for binding and detection of NO is achieved at the smallest packing densities. This finding is relevant to all molecular sensor films with axial binding of analytes to the sensor molecules and demonstrates the advantage of sensor molecule assembly into monolayers on water‐air interfaces using the LB technique.
A mixed methods investigation of reasons underlying fear of positive evaluation
Authors: Wilson Gillian A. , Malivoire Bailee L. , Cassin Stephanie E. , Antony Martin M. 
Published: December 2022

AbstractFear of negative evaluation (FNE) is a hallmark feature of social anxiety disorder (SAD). There is also evidence that people with SAD fear receiving positive evaluation and that fear of positive evaluation (FPE) is distinct from FNE. However, researchers have speculated that concerns related to negative evaluation may actually underlie FPE. This study sought to advance our understanding of FPE by employing both quantitative and qualitative methods to assess the reasons underlying participants' endorsement of FPE on the Fear of Positive Evaluation Scale and the extent to which these reasons reflect FNE versus FPE in a sample of individuals with SAD (n = 47) and a nonclinical comparison group (n = 49). Results indicated that responses to the FPES items primarily reflected an underlying FNE. Consistent with contemporary cognitive–behavioural theories of SAD, fear of proximal or eventual negative judgement emerged as the most common reason for participants' responses on the FPES. However, participants reported other reasons that did not reflect FNE, such as fear of hurting people's feelings and uncertainty associated with positive evaluation. All of the reasons underlying participants' ratings on the FPES were reported by both the SAD group and the nonclinical comparison group; however, individuals with SAD endorsed each of the reasons to a greater extent. These findings suggest that the FPES does not exclusively assess FPE as intended; however, the emergence and endorsement of reasons other than FNE suggest that FPE exists as a distinct construct.

AbstractCovalent triazine frameworks (CTFs) and their derivative N‐doped carbons have attracted much attention for application in energy conversion and storage. However, previous studies have mainly focused on developing new building blocks and optimizing synthetic conditions. The use of isometric building blocks to control the porous structure and to fundamentally understand structure–property relationships have rarely been reported. In this work, two isometric building blocks are used to produce isometric CTFs with controllable pore geometries. The as‐prepared CTF with nonplanar hexagonal rings demonstrates higher surface area, larger pore volume, and richer N content than the planar CTF. After pyrolysis, nonplanar porous CTF‐derived N‐doped carbons exhibit admirable catalytic activity for oxygen reduction in alkaline media (half‐wave potential: 0.86 V; Tafel slope: 65 mV dec−1), owing to their larger pore volume and the abundance of pyridinic and graphitic N species. When assembled into a zinc–air battery, the as‐made electrocatalysts show high capacities of up to 651 mAh g−1 and excellent durability.

Published: December 2022

AbstractGrouting is an effective method to improve the integrity and stability of fractured rocks that surround deep roadways. After years of research and practice, various theories and a complete set of grouting technologies for deep roadways with fractured rocks have been developed and are widely applied in Chinese coal mining production. This paper systematically summarizes and analyzes the research results concerning the theory, design, materials, processes, and equipment for the grouting and reinforcement of fractured rocks surrounding deep roadways. Specifically, in terms of grouting methods, pregrouting, grouting‐while‐excavation, and postgrouting methods are explored; in terms of grouting theory, backfill grouting, compaction grouting, infiltration grouting, and fracture grouting theories are studied. In addition, this paper also studies grouting borehole arrangement, water‐cement ratio, grouting pressure, grouting volume, grout diffusion radius, and other grouting parameters and their determination methods. On this basis, this paper explores the physical and mechanical properties of organic and organic‐inorganic composite grouting materials, and assess grouting reinforcement quality testing methods and instruments. Taken as the field cases, the application of pregrouting in front of heading faces, grouting‐while‐excavation, and postgrouting in the Kouzidong coal mine are then introduced, and the effects of the grouting reinforcements are evaluated. This paper proposes a development direction for grouting technology based on problems existing in the grouting reinforcement of fractured rocks surrounding deep roadways.
