AbstractThe technological promise of soft devices—wearable electronics, implantables, soft robotics, sensors—has accelerated the demand for deformable energy sources. Devices that can convert mechanical energy to electrical energy can enable self‐powered, tetherless, and sustainable devices. This work presents a completely soft and stretchable (>400% strain) energy harvester based on variable‐area electrical‐double‐layer (EDL) capacitors (≈40 µF cm−2). Mechanically varying the EDL area, and thus the capacitance, disrupts equilibrium and generates a driving force for charge movement through an external circuit. Prior EDL capacitors varied the contact area by depressing water droplets between rigid electrodes. In contrast, here, the harvester consists of liquid‐metal electrodes encased in a hydrogel. Deforming the device by ≈25% strain generates a power density ≈0.5 mW m−2. This unconventional approach is attractive because: (1) it does not need an external voltage supply to provide charge; (2) the electrodes themselves deform; and (3) it can work under various modes of deformation such as pressing, stretching, bending, and twisting. The unique ability of the harvester to operate underwater shows promising applications in wearables that contact sweat, underwater sensing, and blue energy harvesting.

Published: August 2021

AbstractOil leakage and discharge of industrial organic solvents are the main reasons for the oily wastewater. The separation of oil/water emulsions has been a global challenge due to the small particle size of the emulsions and their stabilities. An effective method is needed to resolve these issues. Superwettability membrane method has demonstrated a high separation efficiency, fast separation speed, low energy consumption, good scalability, easy operation, and recyclability. In essence, the special wettability of material is mainly determined by two factors: the chemical compositions of material surface and the surface morphology. Herein, in this review, the development of special wettability separation membranes is discussed including different preparation methods, and material preparation, such as superhydrophobic/super lipophilic, superhydrophilic/underwater superoleophobic, superlipophilic/superhydrophobic under oil, smart membranes with switchable wettability, and special wettability membranes with self‐healing or self‐cleaning property. The representative works of each part are introduced, focusing on preparation methods, innovations and separation performance of membranes. Finally, challenges and future directions in this field are also described.

AbstractThe hydrovoltaic effect is a recently‐developed means to directly generate electric power from omnipresent water resources, which has drawn substantial attention in the energy harvesting and conversion domain. Unfortunately, the output power density significantly lags behind the other power generation ways. Although numerous efforts have been made to develop various active materials catering to improved output, yet less attention has been paid to the interface between active materials and electrodes. Here, an atomic layer deposition deposited titanium oxide layer is incorporated at rear silicon contact, enabling high surface passivation quality and superior electron selectivity characteristics. As a consequence, the passivated rear contact remarkably enables elevated hydrovoltaic performance, yielding a high open‐circuit voltage of ≈0.82 V and a short‐current density of ≈30 µA cm−2 at room temperature, and the output power density of ≈15 µW cm−2 displays the highest value among previously reported comparable hydrovoltaic devices. This finding that regards the leverage of transition metal oxide as a passivation layer presents a prospective avenue to improve interfacial contact for high‐efficiency hydrovoltaic devices.
Catalyst‐Free Csp−Csp3Cross‐Coupling of Bromodifluoroacetamides with 1‐Iodoalkynes under Visible‐Light Irradiation
Authors: Yamamoto Yoshihiko , Kuroyanagi Eisuke , Suzuki Harufumi , Yasui Takeshi 
Published: August 2021

AbstractWe describe herein that the cross‐coupling of bromodifluoroacetamides with (iodoethynyl)arenes proceeds without recourse to any photocatalyst when exposed to visible light at room temperature to afford alkynyldifluoroacetamides in 62–83% yields (27 examples). Several control experiments suggest that the reaction involves the homolysis of bromodifluoroacetamides and the coupling of the resultant difluoromethyl radical species with the 1‐iodoalkynes via a radical chain process. Divergent transformations of the coupling products led to various organofluorine compounds, demonstrating the synthetic utility of the developed photo‐coupling method.magnified image

Published: August 2021

AbstractLivestock productivity and the resulting economic benefits for smallholder farmers are constrained by a limited supply of quality feed. Gender influences both the drivers and constraints for feed technology adoption as well as the distribution of benefits from feed technologies; however, research with gender‐disaggregated data related to livestock feed practices and technologies has not previously been systematically collected and analyzed. This review examines the current scope and patterns in the literature and highlights opportunities that could benefit future livestock feeding research. The review identified 72 articles with gender‐disaggregated data related to livestock feeding, which were analyzed thematically based on the type of gender data collected: division of labor (44 articles), decision making (eight articles), knowledge (nine articles), and technology adoption (11 articles). Across nine different feed activities, women had a comparatively higher level of involvement than men in 49% of the observations (81), whereas men were more involved than women in 48% of the observations (79); equal involvement accounted for the remaining 3% of the observations (n = 7). However, individual feed tasks showed stronger involvement trends toward men or women. Women were more likely to be involved in the provision of feed to livestock than men (69% of observations, 24 observations), whereas men had higher levels of participation than women in fodder collection (54%, 19 observations) and grazing and herding (65%, 33 observations). Future research on women's roles in feed‐related activities could help to improve adoption, scaling, and sustainability of feed improvement interventions through the use of gender‐sensitive data collection tools.

Published: August 2021

AbstractHerein, we report an asymmetric alicyclic polyamide nanofilm with an enhanced pore interconnectivity established by manipulating the molecular geometric structure, composed of a porous aromatic polyamide dendrimer layer and a dense alicyclic polyamide layer with hollow stripes. The experimental and simulated data demonstrate that the alicyclic polyamide nanofilm with an asymmetric structure exhibits a negative surface charge and contains more interconnected voids ranging from 1.95 to 3.0 Å, which facilitates the rejection of SO42−with a higher charge density and the passage of Cl−with a smaller hydrated radius, resulting in a good Cl−/SO42−separation selectivity. The resulting membrane attains a 197.11 separation selectivity for Cl−and SO42−and a water flux (for Na2SO4) ~2.2 times that of the pristine polyamide membrane. This fine‐tuning pore approach resulting from the considered alicyclic structure can also be employed in other separation membranes, such as membranes for gas, solvent, or neutral molecular separation.

Published: August 2021

AbstractBackgroundFollowing a work‐related permanent impairment, injured workers commonly face barriers to safe and successful return to work (RTW). Examining workers' experiences with the workers' compensation (WC) system could highlight opportunities to improve RTW outcomes. Objectives included summarizing workers': (1) appraisal of several WC‐based RTW programs, and (2) suggestions for vocational rehabilitation and WC system improvements to promote safe and sustained RTW.MethodsIn telephone interviews, 582 Washington State workers with work‐related permanent impairments were asked whether participation in specified WC‐based RTW programs helped them RTW and/or stay at work. Suggestions for program and system improvements were solicited using open‐ended questions; qualitative content analysis methods were used to inductively code responses.ResultsMost respondents reported positive impacts from RTW program participation; for example, 62.5% of vocational rehabilitation participants reported it helped them RTW, and 51.7% reported it helped them stay at work. Among 582 respondents, 28.0% reported that no change was needed to the WC system, while 57.6% provided suggestions or critiques. Reduce delays/simplify process/improve efficiency was the most frequent WC system theme—mentioned by 34.9%. Among 120 vocational rehabilitation participants, 35.8% reported that no change was needed to vocational rehabilitation, while 46.7% (N = 56) provided suggestions or critiques. More worker choice/input into the vocational retraining plan was the most frequent vocational rehabilitation theme—mentioned by 33.9%.ConclusionsThis study's findings suggest that there is substantial room for improvement in workers' experience with the WC system. In addition, injured workers' feedback may reflect opportunities to reduce administrative burden and to improve worker health and RTW outcomes.

AbstractElectrochemical reduction of carbon dioxide (CO2) into chemicals and fuels has recently attracted much interest, but normally suffers from a high overpotential and low selectivity. In this work, single P atoms were introduced into a N‐doped carbon supported single Fe atom catalyst (Fe‐SAC/NPC) mainly in the form of P−C bonds for CO2 electroreduction to CO in an aqueous solution. This catalyst exhibited a CO Faradaic efficiency of ≈97 % at a low overpotential of 320 mV, and a Tafel slope of only 59 mV dec−1, comparable to state‐of‐the‐art gold catalysts. Experimental analysis combined with DFT calculations suggested that single P atom in high coordination shells (n≥3), in particular the third coordination shell of Fe center enhanced the electronic localization of Fe, which improved the stabilization of the key *COOH intermediate on Fe, leading to superior CO2 electrochemical reduction performance at low overpotentials.

Published: August 2021

AbstractExploiting noncovalent π‐interactions particularly emerging anion‐π interactions to drive efficient catalysis is fascinating. Even with exciting progresses, can anion‐π activation operate in water remains elusive. Here we report the design, synthesis and catalytic studies of a class of water‐soluble electron‐deficient molecular cages and relevant aromatic slide compounds. The prism‐like cages contain three divided, long, cationic aromatic walls which constitute three highly electron‐deficient V‐shape cavities. They were efficiently synthesized in two steps from a parent triformyl cage in gram‐scale. Crystal structure showed the π‐walls bind to the counter bromide through strong anion‐π interactions. Just 5 mol% of cages were effective in catalyzing decarboxylative Aldol reactions of aldehydes and malonic acid half thioesters in water but not in organic solvents, showing a pronounced hydrophobic amplification effect. Meantime, a series of single π‐slides resembling the π‐wall of the cage performed equally well, while those lacking an extended π‐surface were ineffective, highlighting the essential role of electron‐deficient π‐face on promoting the conversion.

AbstractCoral reefs have been challenged by the current rate and severity of environmental change that might outpace their ability to adapt and survive. Current research focuses on understanding how microbial communities and epigenetic changes separately affect phenotypes and gene expression of corals. Here, we provide the hypothesis that coral‐associated microorganisms may directly or indirectly affect the coral's phenotypic response through the modulation of its epigenome. Homologs of ankyrin‐repeat protein A and internalin B, which indirectly cause histone modifications in humans, as well as Rv1988 histone methyltransferase, and the DNA methyltransferases Rv2966c, Mhy1, Mhy2, and Mhy3 found in coral‐associated bacteria indicate that there are potential host epigenome‐modifying proteins in the coral microbiome. With the ideas presented here, we suggest that microbiome manipulation may be a means to alter a coral's epigenome, which could aid the current efforts to protect coral reefs.

AbstractBackgroundPatients with hematological malignancies are at an increased risk of SARS‐CoV‐2 disease (COVID‐19) and adverse outcome. However, a low mortality rate has been reported in patients with chronic myeloid leukemia (CML). Preclinical evidence suggests that tyrosine kinase inhibitors (TKIs) may have a protective role against severe COVID‐19.MethodsWe conducted a cross‐sectional study of 564 consecutive patients with CML who were tested for anti‐SARS‐CoV‐2 IgG/IgM antibodies at their first outpatient visit between May and early November 2020 in five hematologic centers representative of three Italian regions.ResultsThe estimated serological prevalence of SARS‐CoV‐2 infection in patients with CML after the first pandemic wave was similar to that in the general population (about 2%), both at national and regional levels. CML patients with positive anti‐SARS‐CoV‐2 serology were more frequently male (p = 0.027) and active workers (p = 0.012), while there was no significant association with TKI treatment type. Only 3 out of 11 IgG‐positive patients had previously received a molecular diagnosis of COVID‐19, while the remainders were asymptomatic or with mild symptoms.ConclusionsOur data confirm that the course of SARS‐CoV‐2 infection in patients with CML is generally mild and reassure about the safety of continuing TKIs during the COVID‐19 pandemic. Furthermore, we suggest that patients with CML succeed to mount an antibody response after exposure to SARS‐CoV‐2, similar to the general population.

Authors: Baydoun Orsola , Buffeteau Thierry , Brotin Thierry 
Published: August 2021

AbstractThis review addresses the synthesis of enantiopure cryptophane and the study of their chiroptical properties. Cryptophane derivatives represent an important class of macrocyclic compounds that can bind a large range of species in solution under different conditions. The overwhelming majority of these host molecules is chiral, and their chiroptical properties have been thoroughly investigated. The first part of this review is dedicated to the optical resolution and the synthesis of enantiopure cryptophane derivatives. In a second part, the study of the chiroptical properties of these molecular hosts by different techniques such as electronic and vibrational circular dichroism and Raman optical activity is detailed. These techniques allow the determination of the absolute configuration of cryptophane derivatives and provide useful information about their conformation in different conditions.

Published: August 2021

SummaryFriendship prediction is an important aspect of a social network. Social network users rely a lot on friendship suggestion as it helps them in improving their network of friends. Moreover it has a huge impact in analyzing whom one is influenced by. In order to know this information it is not only essential to identify the potential friends, but also rank them to quantify their influence. To do this, we propose a learning to rank framework using the most popular machine learning technique, LambdaMART with a new boosting algorithm. Our framework provides unparalleled values of normalized discounted cumulative gain measure. We also analyze which feature of the social network is helpful in getting these nonpareil values. Our boosting algorithm yields an analytical solution for the over‐fitting problem with the increasing number of iterations, thereby augmenting the robustness of the framework.
