Published: September 2019

AbstractAdherent cells residing within tissues or biomaterials are presented with 3D geometrical cues from their environment, often in the form of local surface curvatures. While there is growing evidence that cellular decision‐making is influenced by substrate curvature, the effect of physiologically relevant, cell‐scale anisotropic curvatures remains poorly understood. This study systematically explores the migration behavior of human bone marrow stromal cells (hBMSCs) on a library of anisotropic curved structures. Analysis of cell trajectories reveals that, on convex cylindrical structures, hBMSC migration speed and persistence are strongly governed by the cellular orientation on the curved structure, while migration on concave cylindrical structures is characterized by fast but non‐aligned and non‐persistent migration. Concurrent presentation of concave and convex substrates on toroidal structures induces migration in the direction where hBMSCs can most effectively avoid cell bending. These distinct migration behaviors are found to be universally explained by the cell‐perceived substrate curvature, which on anisotropic curved structures is dependent on both the temporally varying cell orientation and the 3D cellular morphology. This work demonstrates that cell migration is dynamically guided by the perceived curvature of the underlying substrate, providing an important biomaterial design parameter for instructing cell migration in tissue engineering and regenerative medicine.

AbstractTextile‐based electronics enable the next generation of wearable devices, which have the potential to transform the architecture of consumer electronics. Highly conductive yarns that can be manufactured using industrial‐scale processing and be washed like everyday yarns are needed to fulfill the promise and rapid growth of the smart textile industry. By coating cellulose yarns with Ti3C2Tx MXene, highly conductive and electroactive yarns are produced, which can be knitted into textiles using an industrial knitting machine. It is shown that yarns with MXene loading of ≈77 wt% (≈2.2 mg cm−1) have conductivity of up to 440 S cm−1. After washing for 45 cycles at temperatures ranging from 30 to 80 °C, MXene‐coated cotton yarns exhibit a minimal increase in resistance while maintaining constant MXene loading. The MXene‐coated cotton yarn electrode offers a specific capacitance of 759.5 mF cm−1 at 2 mV s−1. A fully knitted textile‐based capacitive pressure sensor is also prepared, which offers high sensitivity (gauge factor of ≈6.02), wide sensing range of up to ≈20% compression, and excellent cycling stability (2000 cycles at ≈14% compression strain). This work provides new and practical insights toward the development of platform technology that can integrate MXene in cellulose‐based yarns for textile‐based devices.

Published: September 2019

AbstractIII‐nitride semiconductors have attracted considerable attention in recent years owing to their excellent physical properties and wide applications in solid‐state lighting, flat‐panel displays, and solar energy and power electronics. Generally, GaN‐based devices are heteroepitaxially grown on c‐plane sapphire, Si (111), or 6H‐SiC substrates. However, it is very difficult to release the GaN‐based films from such single‐crystalline substrates and transfer them onto other foreign substrates. Consequently, it is difficult to meet the ever‐increasing demand for wearable and foldable applications. On the other hand, sp2‐bonded two‐dimensional (2D) materials, which exhibit hexagonal in‐plane lattice arrangements and weakly bonded layers, can be transferred onto flexible substrates with ease. Hence, flexible III‐nitride devices can be implemented through such 2D release layers. In this progress report, the recent advances in the different strategies for the growth of III‐nitrides based on 2D materials are reviewed, with a focus on van der Waals epitaxy and transfer printing. Various attempts are presented and discussed herein, including the different kinds of 2D materials (graphene, hexagonal boron nitride, and transition metal dichalcogenides) used as release layers. Finally, current challenges and future perspectives regarding the development of flexible III‐nitride devices are discussed.

Published: September 2019

AbstractFeaturing the dendrimer‐like properties, the cross‐linked small‐molecule micelles (cSMs) have been shown to be a good alternative to dendrimers in many applications. Following this trend, herein the copper(I)‐chelated cross‐linked cyclen micelles (CuI@cCMs) were created as a nanocatalyst for azide‐alkyne cycloaddition. Both alkynes and azides with diverse structures performed with excellent reactivity in water at the parts‐per‐million (ppm) catalyst usage. Recycle experiments disclosed that the nanocatalyst had only slight decrease of catalytic efficiency after reusing many times. Importantly, the CuI@cCMs could easily enter cells and carry out the intracellular catalysis for lighting up and/or killing cancer cells.magnified image
Continuous Flow Routes toward Designer Metal Nanocatalysts
Authors: Santana Joshua S. , Skrabalak Sara E. 
Published: September 2019

AbstractMono‐ and multimetallic nanoparticles (NPs) have diverse and tunable physicochemical properties that arise from their compositions as well as crystallite size and shape. The ability to control precisely the composition and structure of NPs through synthesis is central to achieving state‐of‐the‐art designer metal NPs for use as catalysts and electrocatalysts. However, a major limitation to the use of designer metal NPs as catalysts is the ability to scale their syntheses while maintaining structural precision. To address this challenge, continuous flow routes to metal NPs involving the use of droplet microreactors are being developed, providing the synthetic versatility necessary to achieve known and completely new nanostructures. This progress report outlines how the chemistry and process parameters of droplet microreactors can be used to achieve high performing nanocatalysts through control of NP composition, size, shape, and architecture and outlines directions toward previously unimaginable nanostructures.

AbstractA smart window that dynamically modulates light transmittance is crucial for building energy efficiently, and promising for on‐demand optical devices. The rapid development of technology brings out different categories that have fundamentally different transmittance modulation mechanisms, including the electro‐, thermo‐, mechano‐, and photochromic smart windows. In this review, recent progress in smart windows of each category is overviewed. The strategies for each smart window are outlined with particular focus on functional materials, device design, and performance enhancement. The advantages and disadvantages of each category are summarized, followed by a discussion of emerging technologies such as dual stimuli triggered smart window and integrated devices toward multifunctionality. These multifunctional devices combine smart window technology with, for example, solar cells, triboelectric nanogenerators, actuators, energy storage devices, and electrothermal devices. Lastly, a perspective is provided on the future development of smart windows.

Published: September 2019

AbstractIn this study, we respond to calls for strengths‐based Indigenous research by highlighting American Indian and First Nations (Anishinaabe) perspectives on wellness. We engaged with Anishinaabe community members by using an iterative, collaborative Group Concept Mapping methodology to define strengths from a within‐culture lens. Participants (n = 13) shared what it means to live a good way of life/have wellness for Anishinaabe young adults, ranked/sorted their ideas, and shared their understanding of the map. Results were represented by nine clusters of wellness, which addressed aspects of self‐care, self‐determination, actualization, community connectedness, traditional knowledge, responsibility to family, compassionate respect toward others, enculturation, and connectedness with earth/ancestors. The clusters were interrelated, primarily in the relationship between self‐care and focus on others. The results are interpreted by the authors and Anishinaabe community members though the use of the Seven Grandfather Teachings, which provide a framework for understanding Anishinaabe wellness. The Seven Grandfather Teachings include Honesty (Gwayakwaadiziwin), Respect (Manaadendamowin), Humility (Dabaadendiziwin), Love (Zaagi'idiwin), Wisdom (Nibwaakaawin), Bravery/Courage (Aakode'ewin), and Truth (Debwewin).
The role of biocultural approaches in assessing interventions for maternal weight and gestational weight gain
Authors: Hicks Kathryn 
Published: September 2019

AbstractPublic health and other researchers express growing concern for the role of maternal adiposity and gestational weight gain in driving the obesity epidemic and health disparities based on race and class. Biocultural scholars must continue to contribute to conversations on how best to address issues of population health including the developmental context of obesity, drawing from both evolutionary and social theory. I discuss a number of intervention studies designed to address gestational weight gain in low‐income and minority women and consider the degree to which they address the social, political, and economic context, and developmental history of mothers. I further examine the potential for these interventions, focused on the individual behavior of mothers, to contribute to stigma based on socially defined race, class, and body shape and size, and to draw attention away from the powerful economic interests that contribute to and benefit from the obesity epidemic. I end with a discussion of the value of developmental systems theory for thinking critically about obesity and other health interventions.
Relationship between total physical activity and physical activity domains with body composition and energy expenditure among Brazilian adults

Published: September 2019

AbstractObjectiveThe aim of this study was to evaluate the relationship of total physical activity (PA) and its different domains with sex, weight, body mass index, body composition, and resting energy expenditure (REE) among Brazilian adults. The secondary aim was to assess if the Baecke Habitual Physical Activity Questionnaire (BHPAQ) could be used to screen fat mass excess.MethodsThree hundred and sixty‐six volunteers participated. PA was assessed with the BHPAQ, body composition with multifrequency bioelectrical impedance spectroscopy, and REE with indirect calorimetry.ResultsTotal PA and sports/exercise PA were lower in women than men. The participants most active for sports/exercise and leisure‐time/locomotion PA domains had higher fat free mass and phase angle, and lower fat mass and weight than the least active subjects. The occupational PA domain was associated with higher fat mass and weight. REE was associated only with the exercise/sports PA domain. The BHPAQ could discriminate subjects with excess body fat with a 9.375 cutoff point for total PA.ConclusionExercise/sports and leisure‐time/locomotion are PA domains associated with a better body composition. A gender gap still exists in PA, as women are less active than men. The BHPAQ could screen subjects with excess fat mass.

Published: September 2019

BackgroundThis study evaluated the effect of bilateral endoscopic sphenopalatine ganglion block (SPGB) for management of postoperative pain in patients undergoing septoplasty.MethodsSixty septoplasty patients (51.7% male, 48.3% female, aged 18 to 45 years) were randomly assigned to general anesthesia (GA) alone (control) (n = 30) or GA plus endoscopic SPGB (n = 30). Demographic data, duration of surgery, blood loss, postoperative visual analogue scale (VAS) pain scores (upon arrival at the postanesthesia care unit [PACU] and 2, 6, 12, and 24 hours after surgery), overall analgesic usage (end of 24 and 168 hours after surgery), overall satisfaction with the pain control (end of 24 and 168 hours after surgery), and complications (bleeding, nausea and vomiting, and visual disturbance) were recorded.ResultsPain scores upon arrival to the PACU and 2, 6, 12, and 24 hours after surgery were significantly lower in the SPGB group compared to the control group (p < 0.001). Moreover, the SPGB group had significantly lower analgesic requirements and higher satisfaction scores with their pain control at the end of 24 and 168 hours after surgery compared to the control group (p < 0.001). The 2 groups significantly differed in terms of intraoperative blood loss (p = 0.024), and surgery time was longer in the SPGB group compared to the control group (p < 0.001).ConclusionSPGB with bupivacaine is a safe and effective method to reduce pain after septoplasty, and it is a cost‐effective alternative to high doses of analgesics.
Visualizing Progressive Atomic Change in the Metal Surface Structure Made by Ultrafast Electronic Interactions in an Ambient Environment

Published: September 2019

AbstractUnderstanding the atomic and molecular phenomena occurring in working catalysts and nanodevices requires the elucidation of atomic migration originating from electronic excitations. The progressive atomic dynamics on metal surface under controlled electronic stimulus in real time, space, and gas environments are visualized for the first time. By in situ environmental transmission electron microscopy, the gas molecules introduced into the biased metal nanogap could be activated by electron tunneling and caused the unpredicted atomic dynamics. The typically inactive gold was oxidized locally on the positive tip and field‐evaporated to the negative tip, resulting in the atomic reconstruction on the negative tip surface. This finding of a tunneling‐electron‐attached‐gas process will bring new insights into the design of nanostructures such as nanoparticle catalysts and quantum nanodots and will stimulate syntheses of novel nanomaterials not seen in the ambient environment.
Transition‐Metal‐Free Reductive Hydroxymethylation of Isoquinolines
Authors: Reeves Benjamin M. , Hepburn Hamish B. , Grozavu Alexandru , Lindsay‐Scott Peter J. , Donohoe Timothy J. 
Published: September 2019

AbstractA transition‐metal‐free reductive hydroxymethylation reaction has been developed, enabling the preparation of tetrahydroisoquinolines bearing C4‐quaternary centers from the corresponding isoquinolines. Deuterium labelling studies and control experiments enable a potential mechanism to be elucidated which features a key Cannizzaro‐type reduction followed by an Evans–Tishchenko reaction. When isoquinolines featuring a proton at the 4‐position are used, a tandem methylation‐hydroxymethylation occurs, leading to the formation of 2 new C−C bonds in one pot.
Economical, Green, and Safe Route Towards Substituted Lactones by Anodic Generation of Oxycarbonyl Radicals

Published: September 2019

AbstractA new electrochemical methodology has been developed for the generation of oxycarbonyl radicals under mild and green conditions from readily available hemioxalate salts. Mono‐ and multi‐functionalised γ‐butyrolactones were synthesised through exo‐cyclisation of these oxycarbonyl radicals with an alkene, followed by the sp3–sp3 capture of the newly formed carbon‐centred radical. The synthesis of functionalised valerolactone derivatives was also achieved, demonstrating the versatility of the newly developed methodology. This represents a viable synthetic route towards pharmaceutically important fragments and further demonstrates the practicality of electrosynthesis as a green and economical method to activate small organic molecules.

ABSTRACTA series of polyester copolymers was synthesizedviamelt polycondensation of dimethyl terephthalate (DMT), dimethyl isophthalate (DMI), and 1,4‐butanediol (BDO) with dimer acid methyl ester (DAME) monomers, previously prepared by the Diels–Alder reaction of fatty acid methyl esters (FAMEs). We obtained copolymers with the desired composition and a high molar mass characterized by1H NMR, FT‐IR, and SEC. The relationship among the composition, thermal behavior, mechanical properties, and adhesion properties of these copolymers was examined, demonstrating that the DAME‐modified copolymers could be substituted for HMA applications and are comparable to petroleum‐based commercial products. As a result, these polyesters could offer improved sustainability and performance and may be good candidates for hot‐melt adhesive materials. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

Changes to freshwater mussel assemblages after 25 years of impoundment and river habitat fragmentation

Abstract

The Tennessee–Tombigbee Waterway is among the largest and most expensive environmental engineering projects of the 20th century. The waterway accommodates barge navigation between the Tennessee River Drainage and Mobile River Basin through a series of locks, dams, canals, and dredged and diverted streams. These structures have altered riverine habitat and fragmented lotic habitats resulting in isolated freshwater mussel populations in patches of streams such as the East Fork Tombigbee River, where 42 species were known historically.
The first post‐waterway mussel surveys in 1987 and 1988 reported 31 taxa. During 2010 and 2011 surveys, 70 sites were sampled using both timed searches and quadrats and detected 29 extant mussel species. Between 1988 and 2010–2011 the relative abundance of nine mussel taxa decreased, whereas the abundance of 11 taxa increased. The populations of three federally listed species were detected at levels below the detection limits in 1988 as well as three non‐native unionids that appear to have colonized the East Fork Tombigbee River via the Tennessee–Tombigbee Waterway River.
Although mussel abundance and total species richness were relatively unchanged, assemblage composition shifted toward animals typical of smaller streams rather than large rivers. This shift suggests that present‐day East Fork Tombigbee River habitats favour smaller‐bodied, thinner shelled taxa that are laterally compressed and lack shell sculpture. These taxa are likely to be better adapted to hydrologically and hydraulically variable habitats than are thick‐shelled, large bodied, and sculptured mussels.
The results suggest that mussel assemblages are dynamic and may exhibit predictable responses to changes in hydrology, physical habitat conditions, and stream connectivity. However, examinations over broad (20+ yr) temporal scales are needed to observe these shifts. The data demonstrate the value of regular monitoring of diverse mussel assemblages and the importance of stream connectivity and flow modifications to this long‐lived group of benthic invertebrates.

AbstractAIE‐active positional isomers, TTE‐o‐PhCHO, TTE‐m‐PhCHO and TTE‐p‐PhCHO, tetrathienylethene (TTE) derivates with peripherally attached ortho‐/meta‐/para‐formyl phenyl groups, were designed and synthesized. The formyl substitution position can effectively modulate their photophysical properties, mechanochromism and fluorescent response to hydrazine. TTE‐o‐PhCHO and TTE‐m‐PhCHO exhibit remarkable AIE characteristics, and TTE‐p‐PhCHO possesses aggregation‐induced emission enhancement performance. They all exhibit high contrast mechanochromism, and TTE‐m‐PhCHO shows larger red‐shift (164 nm) than TTE‐o‐PhCHO (104 nm) and TTE‐p‐PhCHO (125 nm) due to the more twisted molecular conformation and much looser molecular packing. Moreover, TTE‐o‐PhCHO with a higher contrast color change can be used as ink‐free rewritable paper. In addition, TTE‐p‐PhCHO, as a turn‐on fluorescent probe, can selectively detect hydrazine with significant color changes that are visible by the naked eye . Therefore, the position dependence of groups would be an effective method to modulate the molecular arrangement, as well as develop AIE compounds for mechano‐stimuli responsive materials, ink‐free rewritable papers and chemosensors.
