Published: June 2023

AbstractThe recent and fast‐growing trends related to the development of wearable technologies have raised the need for efficient and high‐performance energy storage devices having extra features such as flexibility and lightweight. Polymer hydrogels, as viscoelastic lightweight porous nanostructures with tunable surface and structural properties, can play a crucial role in the design of these future energy storage devices. Herein, recent developments and progress in the use of polymer hydrogels to design flexible and wearable energy storage devices are presented and discussed. The 3D structure of polymer hydrogels and porous nanostructures based on these hydrogels provides a platform to design flexible supercapacitors, batteries, and personal thermal management devices. Herein, different types of polymer hydrogels are presented, and their main fabrication techniques are reported. Moreover, the main structural properties affecting the energy storage performance of polymer hydrogels are discussed. In addition to recent progress in the design of polymer‐hydrogel‐based wearable devices, recent developments in polymer hydrogels for flexible applications (batteries, supercapacitors, and thermal energy storage systems) are reviewed in detail.

AbstractQuasi‐2D perovskite light‐emitting devices (PeLEDs) show great potential for the next generation of displays due to the surprising improvement of external quantum efficiency (EQE). However, the development of white emission Quasi‐2D PeLEDs is frustrating. One obstacle is inefficient energy transfer among different electroluminescence (EL) emissive phases of the Quasi‐2D perovskite layer. Here, a new strategy is proposed to resolve this problem, which is inducing an external artificial phase as the host material and building a new energy transfer path between the artificial phase and the EL emissive phases of the Quasi‐2D perovskite layer. Blue CdSe/ZnS quantum dots (QDs) are an ideal choice since the size of CdSe/ZnS QDs is similar to that of perovskite grains in Quasi‐2D PeLEDs and has good operational stability. The fabricated PeLEDs show a voltage‐stable 1931 Commission Internationale de L'Eclairage (CIE) coordinate located at the white emission area (0.33,0.33). The highest luminescence is 365.32 cd m−2. The fabricated PeLEDs can maintain the 95% EQE for >500 s, which is ten times higher than pure Quasi‐2D PeLEDs. This work is the first to propose that inorganic QDs can serve as the host material for Quasi‐2D PeLEDs, which offers a powerful tool for researchers to boost the efficiency and stability performance of white emission Quasi‐2D PeLEDs.

AbstractEnyne diesters derived from biaryls and related substrates undergo intramolecular [2+2]‐cycloaddition and concomitant cyclo‐reversion when treated with 10 mol% In(OTf)3 in 1,2‐dichloroethane. This enyne metathesis type cycloisomerization reaction enables the synthesis of phenanthrene, benzophenanthrene, benzotetraphene and other polycyclic (hetero)aromatic compounds bearing a synthetically useful diethyl β‐(hetero)arylidene malonate moiety in a step‐ and atom‐economic manner. In(OTf)3‐catalyzed two independent intramolecular cycloisomerization on substrates 5 a and 5 b provides direct access to benzotetraphenes 6 a and 6 b containing bis(diethyl β‐phenylmethylene malonate) moiety. Tetrasubstituted vinylidene malonate 4 a, substiututed by two different aromatic groups, is stereoselectively converted into E‐ and Z‐isomer of triaryl group containing all carbon tetrasubstituted olefins (8 a, 8 a′ and 8 b) via Pd‐catalyzed stereoselective decarboxylative arylation reaction.

AbstractParkinson's disease (PD) is starting at younger ages. In order to reduce the risk of PD in young people, Rb3 is selected as an active ingredient and assembled into Rb3 nanoparticles (Rb3NPs)encapsulated microbubbles (MBs), shorted for Rb3NPs@MBs. This study uses focused ultrasound‐mediated Rb3NPs@MBs to cross the blood–brain barrier and reach the brain lesions to be intervened in in order to explore the prevention of 1‐methyl‐4‐phenyl‐4‐piperidinpropionate ester (MPTP)‐induced PD by Rb3NPs@MBs and its related mechanisms. In the present study, Rb3NPs@MBs prevent MPTP‐induced tyrosine hydroxylase (TH)‐positive cell decreases, decrease TH expression, increase Park2 expression, and decrease expression of α‐synaptonucleoprotein in the pars compactus nigra (SNc). It is found, in vitro study, that Rb3NPs treatment significantly reverses MPTP‐induced apoptosis and death of PC12/SY5Y cells, which is commonly used mouse/ human neural cell lines. It is also found that Rb3NPs@MBs can prevent the production of reactive oxygen species (ROS) in SNc. Finally, it is found that DJ‐1 expression decreases after Rb3NPs@MBs are introduced. Results suggest that the neuroprotective activity of Rb3NPs@MBs may be achieved by increasing the expression of DJ‐1 and decreasing the production of ROS. Taken together, these data reveal that Rb3NPs@MBs play an important role in preventing memory deficiency in PD.

Published: June 2023

AbstractMonte‐Carlo methods are used to study the influence of stick polydispersity, orientation and clustering on the percolation of sticks in the plane. The results show that for polydisperse stick lengths, the percolation threshold exhibits a linear dependence on the reciprocal of the length‐weighted mean stick length. Reinterpretation of data from the literature confirms this dependence and shows it to persist for oriented networks. Also, the number of intersections per stick at percolation, is independent of orientation for percolation perpendicular to the direction of preferential orientation; in the direction of preferential orientation, it is a linear function of an orientation parameter. For networks of sticks clustered according to a compound Poisson process, a cluster intensity, Ψ is introduced; when this is less than the percolation threshold of a random network of sticks, the percolation threshold increases linearly with cluster intensity and is independent of cluster size. Above this, non‐linear size‐dependent relationships are observed.

AbstractThe number of 2D systems based on Mn and C atoms has been growing significantly due to the magnetic and electronic properties that these monolayers present. In this work, a new Mn‐C monolayer by density functional theory is proposed. The MnC4 stability is studied by the formation energy formalism to compare with other reported Mn‐C monolayers. Our analysis points that the MnC4 monolayer stabilizes at extremely rich C conditions. Also, the MnC4 monolayer possess positive phonon branches, evidencing its dynamic stability. Further, it confirms that this monolayer is also stable up to 300 K. This new monolayer has an antiferromagnetic alignment with spin‐channels along the [‐110] direction and metallic behavior, being a strong candidate in the formation of exchange‐biased systems when forming a van der Waals heterojunction with other Ferromagnetic materials.

AbstractNeural stem cells (NSCs) derived from human pluripotent stem cells (hPSCs) are considered a major cell source for reconstructing damaged neural circuitry and enabling axonal regeneration. However, the microenvironment at the site of spinal cord injury (SCI) and inadequate intrinsic factors limit the therapeutic potential of transplanted NSCs. Here, it is shown that half dose of SOX9 in hPSCs‐derived NSCs (hNSCs) results in robust neuronal differentiation bias toward motor neuron lineage. The enhanced neurogenic potency is partly attributed to the reduction of glycolysis. These neurogenic and metabolic properties retain after transplantation of hNSCs with reduced SOX9 expression in a contusive SCI rat model without the need for growth factor‐enriched matrices. Importantly, the grafts exhibit excellent integration properties, predominantly differentiate into motor neurons, reduce glial scar matrix accumulation to facilitate long‐distance axon growth and neuronal connectivity with the host as well as dramatically improve locomotor and somatosensory function in recipient animals. These results demonstrate that hNSCs with half SOX9 gene dosage can overcome extrinsic and intrinsic barriers, representing a powerful therapeutic potential for transplantation treatments for SCI.
IGFBP1 Sustains Cell Survival during Spatially‐Confined Migration and Promotes Tumor Metastasis

Published: June 2023

AbstractCell migration is a pivotal step in metastatic process, which requires cancer cells to navigate a complex spatially‐confined environment, including tracks within blood vessels and in the vasculature of target organs. Here it is shown that during spatially‐confined migration, the expression of insulin‐like growth factor‐binding protein 1 (IGFBP1) is upregulated in tumor cells. Secreted IGFBP1 inhibits AKT1‐mediated phosphorylation of mitochondrial superoxide dismutase (SOD2) serine (S) 27 and enhances SOD2 activity. Enhanced SOD2 attenuates mitochondrial reactive oxygen species (ROS) accumulation in confined cells, which supports tumor cell survival in blood vessels of lung tissues, thereby accelerating tumor metastasis in mice. The levels of blood IGFBP1 correlate with metastatic recurrence of lung cancer patients. This finding reveals a unique mechanism by which IGFBP1 sustains cell survival during confined migration by enhancing mitochondrial ROS detoxification, thereby promoting tumor metastasis.

AbstractOrganic electrode materials for lithium‐ion batteries have attracted significant attention in recent years. Polymer electrode materials, as compared to small‐molecule electrode materials, have the advantage of poor solubility, which is beneficial for achieving high cycling stability. However, the severe entanglement of polymer chains often leads to difficulties in preparing nanostructured polymer electrodes, which is vital for achieving fast reaction kinetics and high utilization of active sites. This study demonstrates that these problems can be solved by the in situ electropolymerization of electrochemically active monomers in nanopores of ordered mesoporous carbon (CMK‐3), combining the advantages of the nano‐dispersion and nano‐confinement effects of CMK‐3 and the insolubility of the polymer materials. The as‐prepared nanostructured poly(1‐naphthylamine)/CMK‐3 cathode exhibits a high active site utilization of 93.7%, ultrafast rate capability of 60 A g−1 (≈320 C), and an ultralong cycle life of 10000 cycles at room temperature and 45000 cycles at −15 °C. The study herein provides a facile and effective method that can simultaneously solve both the dissolution problem of small‐molecule electrode materials and the inhomogeneous dispersion issue of polymer electrode materials.

AbstractState‐of‐the‐art carbon coatings are sought to protect high‐capacity silicon anodes, which suffer from low conductivity, large volume change and fast degradation. However, this approach falls short when handling physical–electrical disconnections between carbon shells and silicon microparticulate (SiMP) with drastic size variations. Here, a strategy of covalent coating is developed to establish a robust encapsulation structure. The obtained covalent SiC bonds enable an effectively dynamic connection between the electrochemically deforming SiMP and the sliding graphene layers, preventing the evolution of gaps between SiMP and the carbon shell and maintaining persistent electrical connections as well as mechanical toughness. As a result of high structure reversibility, the cycling stability of thick SiMP anodes is greatly improved, up to a high areal capacity of 5.6 mAh cm−2 and volumetric capacity of 2564 mAh cm−3. This interface bonding effect demonstrates the great potential for suppressing deformation involved degradation of high‐capacity materials through coating strategies.

AbstractObjectivesDifferences in talar articular morphology relative to locomotion have recently been found within Pan and Gorilla. Whole‐bone talar morphology within, and shared variation among, Pan and Gorilla (sub)species, however, has yet to be investigated. Here we separately analyze talar external shape within Pan (P. t. troglodytes, P. t. schweinfurthii, P. t. verus, P. paniscus) and Gorilla (G. g. gorilla, G. b. beringei, G. b. graueri) relative to degree of arboreality and body size. Pan and Gorilla are additionally analyzed together to determine if consistent shape differences exist within the genera.Materials and MethodsTalar external shape was quantified using a weighted spherical harmonic analysis. Shape variation both within and among Pan and Gorilla was described using principal component analyses. Root mean square distances were calculated between taxon averages, and resampling statistics conducted to test for pairwise differences.ResultsP. t. verus (most arboreal Pan) talar shape significantly differs from other Pan taxa (p < 0.05 for pairwise comparisons) driven by more asymmetrical trochlear rims and a medially‐set talar head. P. t. troglodytes, P. t. schweinfurthii, and P. paniscus do not significantly differ (p > 0.05 for pairwise comparisons). All gorilla taxa exhibit significantly different talar morphologies (p < 0.007 for pairwise comparisons). The more terrestrial subspecies of G. beringei and P. troglodytes exhibit a superoinferiorly taller talar head/neck complex.DiscussionP. t. verus exhibits talar morphologies that have been previously related to more frequent arboreality. The adaptations in the more terrestrial G. beringei and P. troglodytes subspecies may serve to facilitate load transmission.

AbstractBackgroundThere is clear evidence that the prevalence of primary antibody deficiency (PAD) is higher in patients with recurrent and chronic rhinosinusitis (CRS) than in the general population. The purpose of this multi‐institutional and multidisciplinary evidence‐based review with recommendations (EBRR) is to thoroughly review the literature on rhinosinusitis with PAD, summarize the existing evidence, and provide recommendations on the evaluation and management of rhinosinusitis in patients with PAD.MethodsThe PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through August 2022. Studies on the evaluation and management of rhinosinusitis in PAD patients were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on the evaluation and management principles for PAD were generated.ResultsA total of 42 studies were included in this evidence‐based review. These studies were evaluated on incidence of PAD in rhinosinusitis patients, incidence of rhinosinusitis in PAD patients, and on the different treatment modalities used and their outcome. The aggregate quality of evidence was varied across reviewed domains.ConclusionBased on the currently available evidence, PAD can occur in up to 50% of patients with recalcitrant CRS. Despite the presence of multiple studies addressing rhinosinusitis and PAD, the level of evidence supporting different treatment options continues to be lacking. Optimal management requires a multidisciplinary approach through collaboration with clinical immunology. There is need for higher‐level studies that compare different treatments in patients with PAD and rhinosinusitis.

Published: June 2023

AbstractLewis‐base sites have been widely applied to regulate the properties of Lewis‐acid sites in electrocatalysts for achieving a drastic technological leap of lithium‐oxygen batteries (LOBs). Whereas, the direct role and underlying mechanism of Lewis‐base in the chemistry for LOBs are still rarely elucidated. Herein, we comprehensively shed light on the pivotal mechanism of Lewis‐base sites in promoting the electrocatalytic reaction processes of LOBs by constructing the metal–organic framework containing Lewis‐base sites (named as UIO‐66‐NH2). The density functional theory (DFT) calculations demonstrate the Lewis‐base sites can act as electron donors that boost the activation of O2/Li2O2 during the discharged‐charged process, resulting in the accelerated reaction kinetics of LOBs. More importantly, the in situ Fourier transform infrared spectra and DFT calculations firstly demonstrate the Lewis‐base sites can convert Li2O2 growth mechanism from surface‐adsorption growth to solvation‐mediated growth due to the capture of Li+ by Lewis‐base sites upon discharged process, which weakens the adsorption energy of UIO‐66‐NH2 towards LiO2. As a proof of concept, LOB based on UIO‐66‐NH2 can achieve a high discharge specific capacity (12 661 mAh g−1), low discharged‐charged overpotential (0.87 V) and long cycling life (169 cycles). This work reveals the direct role of Lewis‐base sites, which can guide the design of electrocatalysts featuring Lewis‐acid/base dual centers for LOBs.

Published: June 2023

AbstractLignin solubilization and in situ hydrogenolysis are crucial for reductive catalytic fractionation (RCF) of lignocellulose to aromatic monomers. In this study, we reported a typical hydrogen bond acceptor of choline chloride (ChCl) to tailor the hydrogen‐donating environment of the Ru/C‐catalyzed hydrogen‐transfer RCF of lignocellulose. The ChCl‐tailored hydrogen‐transfer RCF of lignocellulose was conducted under mild temperature and low‐pressure (<1 bar) conditions, which was applicable to other lignocellulosic biomass sources. We obtained an approximate theoretical yield of propylphenol monomer of 59.2 wt % and selectivity of 97.3 % using an optimal content of ChCl (10 wt %) in ethylene glycol at 190 °C for 8 h. When the content of ChCl in ethylene glycol was increased to 110 wt %, the selectivity of propylphenol switched toward propylenephenol (yield of 36.2 wt % and selectivity of 87.6 %). The findings in this work provide valuable information for transforming lignin from lignocellulose into value‐added products.
Aging ofhigh‐performancefibers used in firefighters' protective clothing: State of the knowledge and path forward
Authors: Hoque Md. Saiful , Dolez Patricia I. 
Published: June 2023

AbstractHigh‐performance fibers developed since the 1960s have a wide range of applications including firefighters' protective clothing. Firefighters' protective clothing made of inherently flame‐resistant high‐performance fibers offers excellent protection in the new condition. However, these fibers experience aging as any polymer material. The situation is amplified due to the severe conditions associated with the firefighters' activities. And the consequences of a loss in the performance of the protective clothing can be dramatic for the firefighter's safety. This article provides a comprehensively review of the aging behavior of high‐performance fibers used in firefighters' protective clothing. Residual performance data have been identified both for used firefighter garments as well as fabric specimens subjected to accelerated aging. Research shows that different aging conditions affect the different fibers to a different degree. The specific conditions in which the aging is applied also affects the outcome in terms of loss in performance. Techniques successfully used to quantify the effect of aging on the performance of fire‐resistant fabrics are also briefly mentioned. Finally, the knowledge gained from this analysis of the literature as well as research gaps and further areas of investigation are discussed in this neglected yet critical topic of firefighters' protective clothing aging.

AbstractTo obtain optimal luminescence, 0.12 g of GdVO4:3%Eu3+ nanocrystals (NCs) and different volumes of nitrogen‐doped carbon dots (N‐CDs) crude solution were used as precursors, and the composite synthesized using the hydrothermal deposition method showed optimal luminescence when 11 ml (2.45 mmol) crude solution was used. In addition, similar composites with the same molar ratio as GVE/cCDs(11) were also prepared with the hydrothermal and physical mixing processes. Based on the test results of XRD, XPS, and PL spectra, for the composite GVE/cCDs(11), the highest (lowest) peak intensity of the C–C/C=C (C=O/C=N) bond, which was 1.18 (0.75) times that of GVE/cCDs‐m, indicated most N‐CDs deposition and led to their highest emission intensity under 365 nm excitation, although nitrogen atoms in the composite were shed slightly during the deposition process. Finally, as can be seen from the patterns designed for security applications that the optimally luminescent composite is one of the most promising candidates in the anti‐counterfeiting field.
