Published: July 2022

AbstractThe lotus effect indicates that a superhydrophobic, self‐cleaning surface can be obtained by roughening the topography of a hydrophobic surface. However, attaining high transmittance and clarity through a roughened surface remains challenging because of its strong scattering characteristics. Here, a haze‐free, antireflective superhydrophobic surface that consists of hierarchically designed nanoparticles is demonstrated. Close‐packed, deep‐subwavelength‐scale colloidal silica nanoparticles and their upper, chain‐like fumed silica nanoparticles individually fulfill haze‐free broadband antireflection and self‐cleaning functions. These double‐layered hierarchical surfaces are obtained via a scalable spraying process that permits precise control over the coating morphology to attain the desired optical and wetting properties. They provide a “specular” visible transmittance of >97% when double‐side coated and a record‐high self‐cleaning capability with a near‐zero sliding angle. Self‐cleaning experiments on photovoltaic devices verify that the developed surfaces can significantly enhance power conversion efficiencies and aid in retaining pristine device performance in a dusty environment.

AbstractThe recent growing energy crisis draws considerable attention to high‐performance thermoelectric materials. n‐type bismuth telluride is still irreplaceable at near room temperature for commercial application, and therefore, is worthy of further investigation. In this work, nanostructured Bi2Te3 polycrystalline materials with highly enhanced thermoelectric properties are obtained by alkali metal Na solid solution. Na is chosen as the cation site dopant for n‐type polycrystalline Bi2Te3. Na enters the Bi site, introducing holes in the Bi2Te3 matrix and rendering the electrical conductivity tunable from 300 to 1800 Scm–1. The solid solution limit of Na in Bi2Te3 exceeds 0.3 wt%. Owing to the effective solid solution, the Fermi level of Bi2Te3 is properly regulated, leading to an improved Seebeck coefficient. In addition, the scattering of both charge carriers and phonons is modulated, which ensured a high‐power factor and low lattice thermal conductivity. Benefitting from the synergistic optimization of both electrical and thermal transport properties, a maximum figure of merit (ZT) of 1.03 is achieved at 303 K when the doping content is 0.25 wt%, which is 70% higher than that of the pristine sample. This work disclosed an effective strategy for enhancing the performance of n‐type bismuth telluride‐based alloy materials.

AbstractSolid‐state batteries (SSBs) currently attract great attention as a potentially safe electrochemical high‐energy storage concept. However, several issues still prevent SSBs from outperforming today's lithium‐ion batteries based on liquid electrolytes. One major challenge is related to the design of cathode active materials (CAMs) that are compatible with the superionic solid electrolytes (SEs) of interest. This perspective, gives a brief overview of the required properties and possible challenges for inorganic CAMs employed in SSBs, and describes state‐of‐the art solutions. In particular, the issue of tailoring CAMs is structured into challenges arising on the cathode‐, particle‐, and interface‐level, related to microstructural, (chemo‐)mechanical, and (electro‐)chemical interplay of CAMs with SEs, and finally guidelines for future CAM development for SSBs are proposed.

Published: July 2022

AbstractN‐coordinated Ni single atom (Ni–NC) is one of the best catalysts for the CO2 reduction reaction (CO2RR) to produce CO. However, no bulk Ni materials have exhibited high catalytic activity for CO2RR. Herein, it is shown that NiS nanoparticles mimicking the electronic structure of Ni–NC in real‐time enhance the CO2RR activity in a zero‐gap electrolyzer. In situ/Operando X‐ray absorption spectroscopy suggests that under a cathodic potential, the electronic structure of NiS changes similarly to that of Ni–NC and modulated Ox–zSy ligands with similar properties to Ni ligands, resulting in a mimicked electronic structure. However, NiS exhibits low stability owing to the loss of S species, key to mimicking N ligands. The future challenges in finding a stable mimicked electronic structure are discussed. Moreover, this work provides new insights into the development of catalysts from materials that have not generally been considered previously.
Clinical significance of sarcopenic dysphagia for patients with esophageal cancer undergoing esophagectomy: A review

Published: July 2022

AbstractThe relationships among esophagectomy for esophageal cancer, dysphagia, and sarcopenia are still unclear. We considered appropriate interventions for patients with resectable esophageal cancer for the purpose of reducing postoperative dysphagia and aspiration pneumonia. Dysphagia in patients with esophageal cancer is caused by patient characteristics, such as pathophysiology and age, or complications after esophagectomy. Recently, sarcopenic dysphagia, defined as dysphagia associated with whole‐body sarcopenia, has attracted attention in various fields, and a large proportion of patients with esophageal cancer are expected to have sarcopenic dysphagia. Our systematic review and meta‐analysis suggested that preoperative sarcopenia in patients with esophageal cancer is related to pulmonary complications after esophagectomy, and some reports also suggested that sarcopenia in swallowing‐related muscles, such as the geniohyoid muscle and tongue, might be associated with postoperative pneumonia or dysphagia after esophagectomy. However, clinical studies on sarcopenic dysphagia in patients with esophageal cancer have been limited. To prevent sarcopenic dysphagia after esophagectomy, perioperative interventions involving not only swallowing rehabilitation, but also physical exercise and nutritional support are important. Moreover, several reports have suggested that the chin‐down maneuver might be effective for preventing aspiration after an esophagectomy. To inhibit the progression of sarcopenic dysphagia after esophagectomy, evaluations and interventions by multidisciplinary staff are likely to be necessary.
Pride in our community: Reflecting on LGBTQ publications in the American Journal of Community Psychology

Published: July 2022

AbstractIn this Virtual Special Issue (VSI), we curate and discuss a set of 28 articles previously published in the American Journal of Community Psychology (AJCP) focused on lesbian, gay, bisexual, transgender, and queer (LGBTQ) communities. The purpose of this VSI is to bring visibility to this body of scholarship in AJCP and to reflect on how the strengths of our field have been used throughout this work in pursuit of supporting LGBTQ wellbeing. In this VSI, we first discuss articles that help to set the historical background for publications in AJCP. We then discuss papers under the broad themes of HIV/AIDS, identities within ecological context, and social activism among LGBTQ communities. We then reflect on opportunities for our field to further leverage our strengths in contributing to LGBTQ scholarship. Overall, this VSI celebrates the contributions to LGBTQ research already present in AJCP, and we hope inspires future contributions to the pages of AJCP and beyond.

AbstractBackgroundCentral compartment atopic disease (CCAD) is a newly reported subset of chronic rhinosinusitis. It was considered associated with inhalant antigen. However, CCAD in Chinese population is not fully studied yet.DesignProspective cohort study.ObjectiveThis study aimed to describe the clinical manifestations of CCAD and compared the following two subtypes: sinonasal polyps and concomitant polypoid disease in the central compartment (CRSwNP/CC) and CRSwNP not otherwise specified (CRSwNP NOS). Also, we compared the clinical manifestations of atopy CCAD and non‐atopy CCAD.MethodsWe consecutively enrolled CRSwNP patients without prior sinus surgery, and assessed the nasal endoscopy and computed tomography of the paranasal sinuses. Allergy was confirmed by skin or serum testing. Eosinophilic CRSwNP (ECRS) was considered as tissue eosinophils to total inflammatory cells >10%.ResultsWe enrolled a total of 116 patients, including 39 with CCAD, 38 with CRSwNP/CC and 39 with CRSwNP NOS. Atopy was detected in 37.1% of the CCAD group, an incidence showing no significant difference from those in the other two groups (37.1% in the CRSwNP/CC group, 31.0% in the CRSwNP NOS group; p = 0.846). However, the incidence of ECRS in the CCAD group was the highest among the different groups (97.4% in the CCAD group vs. 67.6% in the CRSwNP/CC group vs. 35.1% in the CRSwNP NOS group; p = 0.000). In addition, the incidence of asthma in the CCAD group (33.3%) was significantly higher than that in the CRSwNP NOS group (10.3%), but quite similar to CRSwNP/CC (34.2%). In the subgroup analysis of CCAD, only total serum IgE and sIgE demonstrated significant differences between atopy CCAD and non‐atopy CCAD.ConclusionCCAD in Southern China may associate with asthma and significant eosinophilia, with a lower incidence of systemic allergy based on skin and serum testing.

AbstractIntroductionLongitudinal multivariable analyses are needed to determine if the rate of olfactory decline during normal cognition predicts subsequent Alzheimer's disease (AD) diagnoses and brain dysmorphology.MethodsOlder adults (n = 515) were assessed annually for odor identification, cognitive function and dementia clinical diagnosis (max follow‐up 18 years). Regional gray matter volumes (GMV) were quantified (3T MRI) in a cross‐sectional subsample (n = 121). Regression models were adjusted for APOE‐ε4 genotype, dementia risk factors and demographics.ResultsFaster olfactory decline during periods of normal cognition predicted higher incidence of subsequent MCI or dementia (OR 1.89, 95% CI: 1.26, 2.90, p < 0.01; comparable to carrying an APOE‐ε4 allele) and smaller GMV in AD and olfactory regions (β = −0.11, 95% CI −0.21, −0.00).DiscussionRapid olfactory decline during normal cognition, using repeated olfactory measurement, predicted subsequent cognitive impairment, dementia, and smaller GMVs, highlighting its potential as a simple biomarker for early AD detection.Highlights
Rate of olfactory decline was calculated from olfactory testing over ≥3 time points.
Rapid olfactory decline predicted impaired cognition and higher risk of dementia.
Neurodegeneration on 3T magnetic resonance imaging was identical in those with olfactory decline and Alzheimer's disease.
Nanographene Metallaprisms: Structure, Stimulated Transformation, and Emission Enhancement
Authors: Chai Ling , Ju Yang‐Yang , Xing Jiang‐Feng , Ma Xiao‐Hui , Zhao Xin‐Jing , Tan Yuan‐Zhi 
Published: July 2022

AbstractNanographenes are inclined to assemble into stacked columnar structures that are stabilized by π‐π interactions, whereas other supramolecular structures of nanographenes, such as prisms and cages, are rarely investigated. Herein, a diazananographene was synthesized, and then assembled with a coordination unit, thereby producing a triangular metallaprism. After adding C60 or C70, the triangular metallaprism was transformed into a square tetramer, which encapsulated a pair of C60 or C70 molecules. The formed host‐guest complex demonstrated efficient energy transfer from the diazananographene shell to the C60 cores. The emission intensity of the capsulated C60 was enhanced remarkably, compared with free C60, due to an increased quantum yield and optical absorption coefficient. This work demonstrates the versatility of nanographene‐based supramolecular architectures beyond columnar stacking and their ability to enhance the emission of otherwise non‐emissive fullerene.

Published: July 2022

AbstractSolid polymer electrolytes (SPEs) with LiTFSI (lithium bis(trifluoromethane sulfonimide)) are promising candidates for solid‐state batteries, owing to their good interfacial contact with solid electrodes. Here, three copolymerized polyethers were prepared as SPEs, using the catalysts of SnF2or SnF2‐LiPF6. The thermal depolymerization of these polyethers was observed at elevated temperatures, which limits their operating temperature ranges. Once the catalyst is removed, the thermal degradation temperatures of these SPEs are raised by 30–55 °C, together with improved thermal performance in cells. For SPEs, the high price of LiTFSI is an obstacle for their large‐scale application, and it's recycling is hindered by the strong interaction with polymers. By the thermal depolymerization of polyethers, LiTFSI can be easier reclaimed from above mentioned SPEs and even the commercial PEO(poly(ethylene‐oxide)) based SPE in rates of 70–80 %, providing a low‐cost strategy for the recycling of LiTFSI.
Stereoretentive Regio‐ and Enantioselective Allylation of Isoxazolinones by a Planar Chiral Palladacycle Catalyst
Authors: Yu Xin , Hu Lingfei , Frey Wolfgang , Lu Gang , Peters René 
Published: July 2022

AbstractThe catalytic allylic substitution is one of the most important tools in asymmetric synthesis to form C−C bonds in an enantioselective way. While high efficiency was previously accomplished in terms of enantio‐ and regiocontrol using different catalyst types, a strong general limitation is a very pronounced preference for the formation of allylic substitution products with (E)‐configured C=C double bonds. Herein, we report that with a planar chiral palladacycle catalyst a diastereospecific reaction outcome is achieved using isoxazolinones and allylic imidates as substrates, thus maintaining the C=C double bond geometry of the allylic substrates in the highly enantioenriched products. DFT calculations show that the reactions proceed via an SN2 mechanism and not via π‐allyl Pd complexes. Crucial for the high control is the stabilization of the allylic fragment in the SN2 transition state by π‐interactions with the phenyl substituents of the pentaphenylferrocenyl catalyst core.

N‐heterocyclic carbene (NHC) complexes of gold(I/III) attained immense interest in catalytic organic transformations and as anticancer agents against several types of human cancers; however, their potential as electrocatalysts is scarce. The electrocatalytic oxygen evolution reaction was performed for the first time using pyridine‐functionalized NHC gold(I) binuclear metallacycles (8 and 9) possessing aptly designed ligand field. Complexes were prepared by the transmetallation of corresponding silver(I) NHC complexes, which were prepared by in situ deprotonation of pyridine and aryl substituted 1,2,4‐triazolium hexafluorophosphate salts (6 and 7) with Ag2O under dark. Both triazolium salts and binuclear gold(I) metallacycles were thoroughly characterised by NMR and ATR‐IR spectral and elemental analyses. A bromide salt 4 and a binuclear gold complex 9 were elucidated for structure by single crystal X‐ray diffraction analysis. Complex 9 possesses distorted linear coordination geometry around the gold atoms by the coordination of carbene carbon and pyridine nitrogen atoms bearing close Au–Au interaction (3.251 Å). The binuclear gold complexes 8 and 9 (along with 10 wt% conductive mesoporous carbon) were investigated as molecular electrocatalysts in oxygen evolution reaction (OER), which evidenced an oxygen evolution overpotential of 2.422 and 2.370 V versus reversible hydrogen electrode (RHE), respectively, to attain a current density of 10 mA.cm−2. The Tafel slope values of 40.9 and 30.4 mV dec−1 for 8 and 9, respectively, indicate the reaction mechanism involved and the suitability of these complexes as apt electrocatalysts for OER. The stability of the prepared molecular electrocatalysts was investigated by cyclic voltammetry and chronoamperometry techniques.

AbstractFour new oligo(azine)s were synthesized from dimethyldiphenylsilane and tetraphenylsilane core‐based dialdehydes and hydrazine by high‐temperature polycondesation and proposed as materials for optoelectronic applications. The oligo(azine)s were characterized by EA, FT‐IR, and NMR. Although most of samples were poorly soluble, TPS‐containing PAZ‐4 was soluble in aprotic polar solvents. According to SEC and FT‐IR studies, the samples were oligomers with up to five repeating units long. TGA showed highly stable samples with TDT10%over 420°C except for PAZ‐1 that contains a DMS core along with phenyl units, and thus, the lowest carbon content in the series. From DSC analysis, the substitution of phenyl groups in PAZ‐1/3 by biphenyl moieties in PAZ‐2/4 allowed to obtain oligo(azine)s with lowerTgvalues. PAZ‐4 showed a UV‐A absorption with optical band‐gap values of 2.91 and 2.65 eV from UV–vis (solution) and DRS (films), respectively. PL analysis showed a violet emission. PAZ‐4 showed resistivity of 29.24 Ω cm, similar to wide‐band gap materials. Their contact angle measurements showed a critical surface tension of 42.29 dynes/cm, revealing its hydrophobicity. AFM analysis indicated that the PAZ‐4 films had homogeneous surfaces. Young's modulus close to 4.46 GPa was established by microindentation for the PAZ‐4 thin‐films.

AbstractInflammatory bowel diseases (IBDs) are characterized by abnormal, non‐antigen specific chronic inflammation of unknown etiology. Genome‐wide association studies show that many IBD genetic susceptibility loci map to immune function genes and compelling evidence indicate that environmental factors play a critical role in IBD pathogenesis. Clinical and experimental evidence implicate the pro‐inflammatory cytokine IL‐15 in the pathogenesis of IBD. IL‐15 and IL‐15α expression is increased in the inflamed mucosa of IBD patients. IL‐15 contributes to the maintenance of different cell subsets in the intestinal mucosa. However, very few studies have addressed the role of IL‐15 in pre‐clinical models of colitis. In this study, we use three well‐characterized models of experimental colitis to determine the contribution of IL‐15 to pathological intestinal inflammation.

AbstractThe rapid, sensitive, and selective detection of ascorbic acid (AA) is of significance in medical assays and diagnostics. In this work, a new aminoperylenediimide (APDI) derived ratiometric fluorescent probe based on the specific redox reaction of cobalt oxyhydroxide (CoOOH) and AA was constructed. APDI exhibited dual fluorescence emission peaks at 549 and 596 nm with an excitation wavelength of 494 nm. In the presence of CoOOH, the dual fluorescence could be quenched. The dominant fluorescence quenching mechanism was caused by the inner filter effect. Using the red emission as a reference, the fluorescence intensity ratio (F549/F596) was linearly correlated with the concentration of AA over a range of 0.05 to 1 μM. The limit of detection for AA was found to be 17 nM. Importantly, the probe was successfully used to detect AA in living cells. Therefore, this high sensitivity and selectivity strategy could directly survey the AA levels in real samples.

AbstractTransfection of nucleic acid molecules into mammalian cells can be facilitated using viral vectors, electroporation, or biocompatible cationic materials. However, safety issues and the requirement of specialized equipment limits the use of viral vectors and physical methods of transfection like electroporation and microinjection, respectively. Biocompatible cationic lipids and polymers like branched‐polyethyleneimine (bPEI) have a wide transfection range and are user‐friendly in most applications. However, bPEI exhibits low transfection efficiency in most cell types. In the present work, we have crosslinked the hexanoyl group to bPEI using anhydride chemistry to enhance its efficiency as a transfection reagent. The efficient association of hexanoyl group to bPEI was assessed using Fourier‐transform infrared spectroscopy and other physicochemical methods. Hexanoyl‐modified bPEI (FA6‐bPEI) was found to exhibit significantly enhanced transfection efficiency in both cell lines and cultured primary cells, as compared to native bPEI and the commercially available transfection reagent, Lipofectamine 3000. Furthermore, our in vitro studies indicated that FA6‐bPEI can be used for robust transfection for increased production of therapeutic proteins in a cell culture‐based system. These results suggested that hexanoyl‐modified bPEI can serve as an efficient transfection reagent for studies on hard‐to‐transfect cells and for enhanced production of therapeutic proteins in vitro.
