AbstractSemiconductive hydrogels denote a strategically valuable platform associated with interdiscipline fields by double advantages of metals and organisms (eco‐friendliness, structural flexibility, mixed conduction, real‐time responsiveness, scalable fabrication, and chemical stability). Nevertheless, the orthodox chemical/physical methods processing hydrogels yield planar‐like layers or rough structures without ultrafine feature size or manipulative performance, falling short of µ‐robotics, µ‐electronics, or n‐energy industries. Thereby, scaling the device's volume down and unleashing material's potential become crucially important for broadband applications. A femtosecond laser lifting‐off technique is synthesized with self‐assembly to break conventional volume/resolution limitation, enlarge the geometry‐design capacity, and desirable electricity conduction for micro/nanosituations. Low‐dimensional high‐performance nanowires, electric circuits, ultrathin interdigital capacitors, manipulative photon filters, and metasurfaces are functionalized here. The repeated experiment concludes a high‐density integration ability with a subminiature size down to 10 × 10 × 0.02 µm3, tunable electric conductivity up to 1.17 × 105 S m−1, and areal capacitance >16.2 mF cm−2 for energy storage higher than those electrochemical double‐layer ones. Large geometry capacity with nanometric resolution provides access to future‐perspective optoelectronic products, n‐energy, bioneural recordings, or interfaces of embedding conditions.

Published: November 2021

AbstractLarge‐scale accrual of snow and ice on solar arrays in northern latitudes can cause significant power generation losses during winter. Depending on environmental conditions, snow can encompass a wide range in physical characteristics from dry snow (modulus ≈100 kPa and density ≈0.1 g cm−3) to bulk ice (modulus ≈8 GPa and density ≈0.9 g cm−3). This variation in snow morphology has made the development of a passive, broad‐spectrum, snow and ice‐shedding surface challenging. Here, the authors develop one of the first surfaces that simultaneously possesses both low‐interfacial strength (τ˄ice < 50 kPa) and toughness (Γice < 0.5 J m−2) with ice. These surfaces, fabricated via the addition of mobile polymer chains/oils to a thin polymeric coating, require extremely low detachment forces for ice, enabling its passive shedding at virtually any accretion length scale. Preliminary evidence that the new surfaces can shed different forms of snow and ice from field‐deployed solar arrays, over a range of subzero temperatures for several weeks, leading to significant increases in power generation is provided. The optically transparent surfaces are easily scalable and can be widely deployed by the solar industry in areas that see persistent snow. Other applications include automotive windshields, LIDAR covers for autonomous vehicles, and cold climate optical sensors.

AbstractA self‐photocatalyzed sulfonylation/cyclization of quinazolinones containing unactivated alkenes with various sulfonyl chlorides was developed. The protocol provides access to sulfonyl radicals via energy transfer from the quinazolinone skeleton to the sulfonyl chloride. Notably, the transformations proceeded without any external photocatalysts, additives, or oxidants, providing an alternative method for fabricating sulfonylated compounds.magnified image

Published: November 2021

AbstractDiode characteristics of transition metal dichalcogenides are studied extensively owing to their electrical and optical properties. In particular, the Schottky barrier diode (SBD) structure has advantages, such as its small leakage current and power consumption, over conventional p–n diodes. This study develops an SBD system using n‐type tungsten disulfide (WS2). By depositing a low work function In (ΦIn = 4.1 eV) and high work function Au (ΦAu = 5.1 eV) on n‐type WS2, the diode characteristics are demonstrated to be close to an ideal diode. The In–Au contacts are measured, and SBD characteristics are confirmed with a 1.02 ideality factor at a zero back‐gate voltage at room temperature and a rectification ratio up to 5 × 102, even at a low temperature (77 K), indicating almost ideal diode properties. In addition, the In electrodes exhibited improved electrical properties, with a high on/off ratio of 107, mobility that is 100 times higher, and Schottky barrier height that is 20 times lower than that of Au electrodes.
Dissident women's letter writing as decolonial plurilogues of relational solidarities for epistemic justice
Authors: Fernández Jesica Siham , Fine Michelle , Madyaningrum Monica Eviandaru , Ciofalo Nuria 
Published: November 2021

AbstractBraiding our words, “dissi‐dance,” and desires, this article engages how various social actors, and communities—which we are a part of and belong to—challenge structural violence, oppression, inequity, and social, racial, and epistemic injustice. We thread these reflections through our written words, in subversive letters which we offer in the form of a written relational conversation among us: a plurilogue that emerges in response to our specific locations, commitments, and refusals, as well as dissents. Our stories and process of dissent within the various locations, relationships, and contexts that we occupy served as the yarn and needle to thread our stories, posed questions and reflections. Braiding, threading and weaving together, we animate deep decolonial inquiries within ourselves, and our different cultural contexts and countries. Refusing individualism—the illusions of objectivity as distance, the academic as expert, and the exile of affect and emotion on academic pages—we choose to occupy academic writing and ask: What if academic writing were stitched with blood and laughter, relationships and insights, rage and incites? What if, at the nexus of critical psychology and decolonizing feminism, we grew an “embodied praxis?” Unlike academic writing, traditionally designed to camouflage affect, connection, relationality and subjectivity, these letters are unapologetically saturated in care and wisdom toward a narrative‐based embodied practice: decolonial plurilogues of relational solidarities for epistemic justice. Our plurilogue of dissent offers a view to advance community research and action with goals of liberation, decoloniality, and community wellness.
The Mechanistic Perspective of IV Iodoxolones
Authors: Chipman Antony 
Published: November 2021

AbstractThe historical development of ortho‐iodoxybenzoic acid (IBX) and the Dess‐Martin periodinane (DMP) is précised to introduce a comprehensive catalogue of the plausible reaction mechanisms that have been proposed to explain their organic chemistry. Each example sourced from the IV iodoxolone mechanistic literature is concisely discussed with reference to relevant structures, presented in the format of a chemical reaction diagram. Where apt, electron pushing arrow annotations systematically inspect electron redistributions typically associated with proton migration assisted bond formation or rupture. Along the journey, reviewing the many facetted repertoire of oxidations that can be accessed by an IV iodoxolone reagent, provides critical insight into the versatility and applications of the mild oxidant(s), the underlying organic chemistry, as well as acknowledgement for the scientists who have unpacked the cornucopia of IV iodoxolone chemistry. A narrative is extolled of a how following the intrinsic reaction coordinate (IRC) using density functional theory (DFT) elucidated the general mechanism of IBX mediated primary (1°) alcohol or 1° amine oxidation, which had previously been the subject of a robust interdisciplinary debate within the chemistry community, as to whether proton abstraction or isomerisation represents the rate determining step.
Effect of molecular weight on inhibition performance of modified polyethyleneimine as polymer corrosion inhibitor for carbon steel in neutral medium
Authors: Chen Tianqi , Chen Mengjin , Fu Chaoyang 
Published: November 2021

AbstractCompared with small organic molecular, polymer corrosion inhibitors exhibit better anti‐corrosion performance in neutral medium because of multiple adsorption sites and temperature toleration, which are becoming the focus of scholars in the field of water treatment. However, the effect of molecular weight of polymer inhibitors is rarely studied, which has a significant impact on its performance. Polyethyleneimine (PEI) containing polar groups and numerous N atoms is a kind of water‐soluble polymer which is prone to being modified, and three kinds of modified polyethyleneimine (PEPA) inhibitors are synthesized by PEI with different molecular weights (600, 1800, 10,000) in this work. The anti‐corrosion performance of PEPA for Q235 carbon steel in neutral medium was evaluated by electrochemical measurements (Tafel polarization plots and electrochemical impendence spectroscopy [EIS]), weight‐loss tests, and surface morphology analysis. Results of weight loss method and other measurements confirm that PEPA is an excellent polymer inhibitor, and the inhibition performance of PEPA synthesized by PEI with molecular weight of 1800 is the best with an inhibition efficiency of 94.6% at a dosage of 200 mg/L at 298 K in neutral medium.

AbstractObjectiveTo explore relationship among self‐injury behavior, experiential avoidance, cognitive fusion, anxiety, and depression in Chinese adolescent patients with nonsuicidal self‐injury (NSSI).MethodsCognitive fusion questionnaire (CFQ), Acceptance and Action Questionnaire—2nd edition (AAQ‐II), adolescent nonsuicidal self‐injury behavior questionnaire (ANSAQ), Hamilton Anxiety Scale (HAMA), and Hamilton Depression Scale (HAMD) were used as research tools to investigate 120 subjects with NSSI and 130 healthy controls.ResultsThe scores of CFQ and AAQ‐II in the NSSI group were significantly higher than those in the healthy control group (p < .001). The results of regression analysis showed that the experiential avoidance score of patients with NSSI could predict the score of self‐injury questionnaire (β = 0.585, p < .001); when predicting anxiety, only CFQ (β = 0.361, p < .001) entered the equation, with an explanatory variation of 12.3%; when predicting depression, CFQ (β = 0.287, p < .01) entered the equation, with an explanatory variation of 7.4%.ConclusionA high level of cognitive fusion and experiential avoidance may be important factors for the maintenance of self‐injury behavior in patients with NSSI.
Dose‐adjusted EPOCH‐R is not superior to sequential R‐CHOP/R‐ICE as a frontline treatment for newly diagnosed primary mediastinal B‐cell lymphoma: Results of a bi‐center retrospective study

AbstractPurposePrimary mediastinal B‐cell lymphoma (PMBCL) is a rare subtype of diffuse large B‐cell lymphoma (DLBCL). Despite its aggressive course, PMBCL is considered curable. While in recent years dose‐adjusted (DA) EPOCH‐R (rituximab, etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin) has become widely endorsed as first‐line therapy for newly‐diagnosed PMBCL, the optimal treatment for this disease and the role of radiotherapy (RT) remains unclear. DA‐EPOCH‐R provides good clinical outcomes, albeit is associated with short‐ and long‐term toxicity. To address this issue, the current retrospective bi‐icenter analysis compared efficacy and toxicity of DA‐EPOCH‐R and a less toxic R‐CHOP/R‐ICE regimen used for the treatment of newly‐diagnosed PMBCL.Patients and MethodsThe study included all patients with a histologically confirmed PMBCL diagnosis treated with DA‐EPOCH‐R or R‐CHOP/R‐ICE between 01/2013‐12/2020 at two tertiary medical centers. Patient demographic and clinical data were derived from institutional electronic medical records. The analysis included 56 patients: 31 received DA‐EPOCH‐R and 25 – R‐CHOP/R‐ICE.ResultsAt a median follow‐up of 1.9 years (IQR 3.1 years), similar progression‐free survival (2.1 versus 2.4 years; p = 0.7667), overall survival (2.5 versus 2.7 years; p = 0.8047) and complete response (80%) were observed in both groups. However, DA‐EPOCH‐R was associated with significantly longer hospitalization required for its administration (p < 0.001) and a trend for higher frequency of infections, stomatitis, thrombotic complications and febrile neutropenia‐related hospitalizations.ConclusionDA‐EPOCH‐R and R‐CHOP/R‐ICE provide similarly encouraging outcomes in newly‐diagnosed PMBCL patients. R‐CHOP/R‐ICE is associated with lower toxicity and significantly reduced hospitalization. Our findings suggest that this regimen may be considered as an alternative to DA‐EPOCH‐R in this patient population.

AbstractBackgroundReliable molecular markers are much needed for early prediction of recurrence in muscle‐invasive bladder cancer (MIBC) patients. We aimed to build a long‐noncoding RNA (lncRNA) signature to improve recurrence prediction and lncRNA‐based molecular classification of MIBC.MethodsLncRNAs of 320 MIBC patients from the Cancer Genome Atlas (TCGA) database were analyzed, and a nomogram was established. A molecular classification system was created, and immunotherapy and chemotherapy response predictions, immune score analysis, immune infiltration analysis, and mutational data analysis were conducted. Survival analysis validation was also performed.ResultsAn eight‐lncRNA signature classifed the patients into high‐ and low‐risk subgroups, and these groups had significantly different (disease‐free survival) DFS. The ability of the eight‐lncRNA signature to make an accurate prognosis was tested using a validation dataset from our samples. The nomogram achieved a C‐index of 0.719 (95% CI, 0.674–0.764). Time‐dependent receiver operating characteristic curve (ROC) analysis indicated the superior prognostic accuracy of nomograms for DFS prediction (0.76, 95% CI, 0.697–0.807). Further, the four clusters (median DFS = 11.8, 15.3, 17.9, and 18.9 months, respectively) showed a high frequency of TTN (cluster 1), fibroblast growth factor receptor‐3 (cluster 2), TP53 (cluster 3), and TP53 mutations (cluster 4), respectively. They were enriched with M2 macrophages (cluster 1), CD8+ T cells (cluster 2), M0 macrophages (cluster 3), and M0 macrophages (cluster 4), respectively. Clusters 2 and 3 demonstrated potential sensitivity to immunotherapy and insensitivity to chemotherapy, whereas cluster 4 showed potential insensitivity to immunotherapy and sensitivity to chemotherapy.ConclusionsThe eight‐lncRNA signature risk model may be a reliable prognostic signature for MIBC, which provides new insights into prediction of recurrence of MIBC. The model may help clinical decision and eventually benefit patients.
When physical closeness induces psychological distance: The effects of psychological ownership and contagion threat on social connectedness
Authors: Kirk Colleen P. , Rifkin Laura Schrier 
Published: November 2021

AbstractThis research examines the effect of a contagion threat on consumers' social connectedness. Across two experiments, we show that when consumers are near others in public places during a pandemic (but not before or after), they psychologically distance themselves by perceiving lower social connectedness. This reduction in social connectedness is higher when consumers have more (vs. less) psychological ownership of the public place (Study 1). Further, the negative effect of psychological ownership on social connectedness found during (but not after) a pandemic is attenuated when consumers do not believe the disease is a severe threat to their own health (Study 2). We examine downstream effects by illustrating that both individual psychological ownership and social connectedness contribute to collective psychological ownership, which in turn enhances stewardship of the public place. The interacting effects of a contagion threat and psychological ownership on stewardship are not explained by territorial infringement, self‐esteem, perceived crowding, positive or negative affect, hope or nostalgia.
MiR‐195‐5p represses inflammation, apoptosis, oxidative stress, and endoplasmic reticulum stress in sepsis‐induced myocardial injury by targeting activating transcription factor 6

Published: November 2021

AbstractMyocardial injury (MI) is a common complication of sepsis. MicroRNAs (miRNAs) have been suggested as potential biomarkers of MI; however, their mechanisms in sepsis‐induced MI remain unclear. A sepsis rat model was constructed by use of cecal ligation and puncture (CLP). The levels of miR‐195‐5p and activating transcription factor 6 (ATF6) expression were determined by quantitative reverse‐transcription polymerase chain reaction, and cytokine levels were detected by ELISA. The levels of oxidative stress (OS)‐related indicators and endoplasmic reticulum stress (ERS)‐related proteins were examined, and the regulatory effect of miR‐195‐5p on ATF6 was determined by using the luciferase reporter assay. Our results showed that miR‐195‐5p expression was downregulated and ATF6 expression was upregulated in lipopolysaccharide‐induced cardiomyocytes and mice with CLP‐induced sepsis. We also found that miR‐195‐5p could markedly attenuate the inflammation, apoptosis, OS, and ERS associated with sepsis‐induced MI. Additionally, we verified that miR‐195‐5p could relieve sepsis‐induced MI by targeting ATF6. This study identified potential targets for treating MI after sepsis.
An Isolable Gallium‐Substituted Nitrilimine and its Reactivity with B−H, Si−H and B−B Bonds

AbstractReaction of the Ga(I) compound NacNacGa (9) with the diazo compound N2CHSiMe3 affords the nitrilimine compound NacNacGa(N‐NCSiMe3)(CH2SiMe3) (10). Carrying out this reaction in the presence of pyridine does not lead to C−H activation on the transient alkylidene NacNacGa=CHSiMe3 but generates a metallated diazo species NacNacGa(NHN=CHSiMe3)(CN2SiMe3) (13) that further rearranges into the isonitrile compound NacNacGa(NHN=CHSiMe3)(N(NC)SiMe3) (15). Reactions of 10 with the silane H3SiPh and the borane HBcat furnished products of 1,3 addition to the nitrilimine moiety NacNacGa{N(ERn)NCSiMe3}(CH2SiMe3), whereas reaction with the diborane B2cat2 gave the product of formal nitrene insertion into the B−B bond. DFT calculations suggest that the interaction of 9 with N2CHSiMe3 proceeds through intermediate formation of an alkylidene compound that undergoes CH activation with a second molecule of N2CHSiMe3. Insertion into the B−B bond likely proceeds through an initial 1,3‐addition of the diborane, followed by boryl migration to the former nitrene center.

Published: November 2021

AbstractTwo new sodium aluminum borates, Na3AlB8O15 and Na3Al2B7O15, have been successfully synthesized by the high‐temperature solution method. They crystallize in the different space groups, P21/c and P2/c, respectively. The B−O configurations of β‐Na2B6O10, Na3AlB8O15 and Na3Al2B7O15 are compared to feature complicated different dimensional open‐framework structures caused by the substitution of [BO4] by [AlO4] covalent tetrahedra. Moreover, the experimental results indicate that Na3AlB8O15 and Na3Al2B7O15 have short ultraviolet (UV) cutoff edges (<187 nm). The first‐principles calculations show that Na3AlB8O15 and Na3Al2B7O15 have moderate birefringence (0.075 and 0.041@1064 nm, respectively).
Membrane Catalysis: N2O Decomposition over La0.2Sr0.8Ti0.2Fe0.8O3–δ Membrane with Oxygen Permeability

Published: November 2021

AbstractCompared to conventional heterogeneous catalysis, membrane catalysis can facilitate in situ removal of inhibiting species on a catalyst, therefore effectively increases the reaction rate. Herein, kinetically controlled decomposition of N2O was studied employing a La0.2Sr0.8Ti0.2Fe0.8O3–δ (LSTF) perovskite membrane, and the direct catalytic N2O decomposition over membrane surface was compared with membrane catalysis of N2O decomposition involving in situ oxygen removal. In the case of membrane catalysis, oxygen produced from N2O conversion can be in situ removed by using a LSTF oxygen‐permeable membrane, thus increasing the amount of surface active sites for N2O decomposition. By sweeping hydrogen at one side of the membrane to consume the permeated oxygen from the other side N2O conversion was improved.

Published: November 2021

Comprehensive SummaryA selective monodefluorinative alkylation of 3,3‐difluorooxindoles is achieved. The reaction starts by the attack of a 4‐dimethylaminopyrine‐boryl radical to the carbonyl oxygen atom of 3,3‐difluorooxindoles, followed by a spin‐center shift to generate radical intermediates with the elimination of a fluoride anion. The subsequent radical addition to alkenes affords a range of 3‐alkyl‐fluorooxindoles products. The strategy offers access to C‐3 functionalized oxindoles with wide substrate scope and tolerates a wide range of functional groups.
