Flexible Pressure Sensors with Wide Linearity Range and High Sensitivity Based on Selective Laser Sintering 3D Printing
Authors: Zhang Tong , Li Zhaoyang , Li Kun , Yang Xiaoniu 
Published: October 2019

AbstractTo achieve practical applications of flexible pressure sensors, good performance and scalable manufacturing processes are both desired. Here, flexible pressure sensors with excellent performance are fabricated via selective laser sintering (SLS). Having benefitted from the irregular microstructures generated in the powder sintering process, the sensors exhibit high sensitivity of 55 kPa−1 in a wide linearity range of 100 kPa, and they maintain decent sensitivity (>10 kPa−1) over a high‐pressure range (100–400 kPa), which is among the best results for flexible pressure sensors. The working mechanism of the sensor is finely revealed combining in situ observations and electrical simulations. The results demonstrate that electrical saturation (due to parasitic resistance) greatly affects the linearity range except for the geometric saturation of the microstructure. As a proof of concept, tactile, pulse, muscle stiffness, and plantar pressure tests are performed. The fast and stable responses of the sensor show its great potential for electronic skin, human–machine interface, and healthcare monitoring. Besides its excellent performance, the fabrication processes via SLS are compatible with fab‐scale production and flexible customization, which pave new paths for the mass manufacturing and diversified applications of flexible pressure sensors in the future.
Chelation of transition metals into MOFs as a promising method for enhancing CO2 capture: A computational study
Authors: Hu Jianbo , Liu Yang , Liu Jing , Gu Chenkai 
Published: October 2019

AbstractMetal organic frameworks (MOFs) are one kind of promising porous materials for CO2 capture and separation. In this work, the chelation of the first‐row transition metals (from Sc to Zn) into MOFs was proposed to enhance its CO2 adsorption capacity. The adsorption mechanisms and adsorption capacities of CO2 in the chelated MOFs were explored by using quantum mechanical calculation and QM‐based grand canonical Monte Carlo simulations. The results show that the chelation of transition metals can significantly improve the adsorption capacity of CO2 in MOFs, especially at low pressure. Among the first row transition metals, the chelation of Mn(II), Fe(II), Co(II), Ni(II), Cu(II), and Zn(II) gives higher binding energies than other transition metals. The chelation of Mn(II) into MOFs shows the highest uptake amount at low pressure. The CO2 uptake amounts in UiO(bpydc)‐MnCl2 and BPV‐MOF‐MnCl2 are about six times higher than the original counterparts at 298 K and 100 kPa. Based on this significant enhancement, the chelation of transition metals in MOFs provides an efficient approach for enhancing CO2 capture.

ObjectiveTo test the hypothesis that Alzheimer's disease and related neuropathologies contribute to the association between hospitalization and cognitive decline in old age.MethodsAs part of a longitudinal clinical–pathologic cohort study, 526 older persons (mean age at death = 90.9 years, 71% female) without dementia at baseline completed annual cognitive testing and were autopsied at death. Hospitalization information was obtained from linked Medicare claims records. Neuropathologic examination assessed β‐amyloid burden, tau tangle density, neocortical Lewy bodies, hippocampal sclerosis, chronic gross and microscopic cerebral infarcts, and transactive response DNA binding protein 43 kDa.ResultsOver a mean of 5.1 years, a total of 1,383 hospitalizations occurred, and the mean annual rate of hospitalization was 0.5 (standard deviation = 0.6, median = 0.4). Higher rate of hospitalization was not directly related to higher burden for any of the neuropathologic markers. Higher rate of hospitalization was associated with more rapid cognitive decline (estimate = −0.042, standard error [SE] = 0.012, p < 0.001), and after controlling for all 7 neuropathologic markers, the association was essentially the same (estimate = −0.040, SE = 0.013, p = 0.002). In a multivariable model with 3‐way interactions of neuropathologic markers with hospitalization rate and time, the association between hospitalization rate and faster cognitive decline was greater in persons with more tangle pathology (estimate for interaction = −0.007, SE = 0.002, p = 0.002) and in persons with neocortical Lewy bodies (estimate for interaction = −0.117, SE = 0.042, p = 0.005).InterpretationOlder persons with more hospitalizations experienced faster rates of cognitive decline, and this association was more pronounced in persons with more tau tangle density and with neocortical Lewy body pathologies.

Asymmetric Synthesis of Oxa‐Bridged Oxazocines through a Catalytic RhII/ZnII Relay [4+3] Cycloaddition Reaction
Authors: Xu Chaoran , Wang Kaixuan , Li Dawei , Lin Lili , Feng Xiaoming 
Published: October 2019

AbstractOxa‐bridged oxazocines bearing three chiral carbon centers were synthesized efficiently through a bimetallic catalytic asymmetric tandem reaction of β,γ‐unsaturated α‐ketoesters with diazoimides. The process contained a rhodium‐promoted in situ generation of isomünchnone from diazoimide decomposition, and a [4+3]‐cycloaddition of β,γ‐unsaturated α‐ketoester catalyzed by a chiral N,N′‐dioxide‐ZnII complex. Ligand‐accelerated catalysis was found, and a possible transition‐state model was proposed to explain the origin of stereoselectivity.
Conformational Entropy as a Means to Control the Behavior of Poly(diketoenamine) Vitrimers In and Out of Equilibrium

Published: October 2019

AbstractControl of equilibrium and non‐equilibrium thermomechanical behavior of poly(diketoenamine) vitrimers is shown by incorporating linear polymer segments varying in molecular weight (MW) and conformational degrees of freedom into the dynamic covalent network. While increasing MW of linear segments yields a lower storage modulus at the rubbery plateau after softening above the glass transition (Tg), both Tg and the characteristic time of stress relaxation are independently governed by the conformational entropy of the embodied linear segments. Activation energies for bond exchange in the solid state are lower for networks incorporating flexible chains; the network topology freezing temperature decreases with increasing MW of flexible linear segments but increases with increasing MW of stiff segments. Vitrimer reconfigurability is therefore influenced not only by the energetics of bond exchange for a given network density, but also the entropy of polymer chains within the network.
Material extrusion‐based additive manufacturing of polypropylene: A review on how to improve dimensional inaccuracy and warpage
Authors: Spoerk Martin , Holzer Clemens , Gonzalez‐Gutierrez Joamin 
Published: October 2019

ABSTRACTMaterial extrusion‐based additive manufacturing (ME‐AM) is an emerging processing technique that is characterized by the selective deposition of thermoplastic filaments in a layer‐by‐layer manner based on digital part models. Recently, it has attracted considerable attention, as this technique offers manifold benefits over conventional manufacturing technologies. However, to meet the challenges of complex industrial applications, certain shortcomings of ME‐AM still need to be overcome. A case in point is the limited amount of semicrystalline thermoplastics, which are still not established as reliable, commercial filament materials. Particularly, polypropylene (PP) offers attractive properties that are unique among the ME‐AM material portfolio. This review describes the current approaches of fabricating PP components by ME‐AM. Both commercial and scientific strategies to make PP 3D‐printable are elaborated and compared. As dimensional issues are especially problematic for PP, a comprehensive section of this review focuses on the strategies developed for mitigating warpage for PP parts fabricated by ME‐AM. © 2019 The Authors.Journal of Applied Polymer Sciencepublished by Wiley Periodicals, Inc.

Effects of silane coupling agent hydrophobicity and loading method on water absorption and mechanical strength of silica particle‐filled epoxy resin

Published: October 2019

ABSTRACTA suitable silane coupling agent (SCA) structure to improve the water absorption and mechanical strength of silica particle‐filled epoxy resin was investigated. Bonding, hydrocarbon, and fluorocarbon type SCAs were employed. The bonding type has glycidoxy or amino groups that react with epoxy resin, whereas the other types have only hydrophobic chains. The spherical silica particles were added to epoxy resin at amounts from 10 to 50 wt %. The effect of water absorption was consequently lowered in the order of hydrocarbon > bonding types. The fluorocarbon type SCA was also effective at zero and low silica content. Modification of the epoxy phase by SCA addition was clarified to have a more dominant effect than the adhesion of silica/epoxy interface for the lowering of water absorption, whereas it had been conventionally considered that interfacial adhesion had a more dominant effect. The mechanical strength was higher for the bonding type than the other type. Two addition methods were compared, a pretreatment method and an integral blend method in which all components were mixed simultaneously. The integral blend method was determined to be superior to the pretreatment method for both water absorption and mechanical strength, which was also contrary to the conventional view. © 2019 Wiley Periodicals, Inc.

Authors: Liu Hang , Perugino Cory A. , Ghebremichael Musie , Wallace Zachary S. , Montesi Sydney B. , Stone John H. , Pillai Shiv 
Published: October 2019

ObjectiveFour autoantigens have been described recently in IgG4‐related disease (IgG4‐RD): prohibitin, annexin A11, laminin 511‐E8, and galectin‐3. However, no external validation has been performed, and the possibility that some individuals break tolerance to more than 1 autoantigen has not been explored. We undertook this study to evaluate the relative frequencies of antibody responses against these autoantigens in order to explore the role of adaptive immune response in IgG4‐RD.MethodsAutoantibody responses against prohibitin, annexin A11, and laminin 511‐E8 were measured among a clinically diverse cohort of IgG4‐RD patients (n = 100) using enzyme‐linked immunosorbent assays. Autoantibody responses were correlated with disease severity and organ distribution.ResultsThe frequencies of IgG4 autoantibody responses against prohibitin (10%), annexin A11 (12%), and laminin 511‐E8 (7%) were not significantly different from those of controls. A portion of the cohort (n = 86) had been analyzed previously at our center for anti–galectin‐3 antibody responses, with 25 patients (29%) having IgG4 anti–galectin‐3 antibodies. Of these 86 patients, 32 (37%) had IgG4 antibodies to ≥1 of the 4 autoantigens and 12 (14%) showed reactivity with ≥2 of the tested antigens. The subset of patients with ≥2 autoantibodies had higher total levels of IgG1, IgG2, IgG4, and C‐reactive protein, were more commonly hypocomplementemic, and were more likely to have visceral organ involvement.ConclusionAntibodies against prohibitin, annexin A11, and laminin 511‐E8 were found in only a small portion of patients with IgG4‐RD. A subset of IgG4‐RD patients, however, had IgG4 antibodies against ≥2 autoantigens. These patients presented with robust IgG subclass elevations, complement consumption, and visceral organ involvement. This broader break in immunologic tolerance in IgG4‐RD was associated with more severe disease.
Ruthenium Catalyzed C−H Acylmethylation of N‐Arylphthalazine‐1,4‐diones with α‐Carbonyl Sulfoxonium Ylides: Highway to Diversely Functionalized Phthalazino‐fused Cinnolines

Published: October 2019

AbstractA direct ortho‐Csp2‐H acylmethylation of 2‐aryl‐2,3‐dihydrophthalazine‐1,4‐diones with α‐carbonyl sulfoxonium ylides is achieved through a RuII‐catalyzed C−H bond activation process. The protocol featured high functional group tolerance on the two substrates, including aryl‐, heteroaryl‐, and alkyl‐substituted α‐carbonyl sulfoxonium ylides. Thereafter, 2‐(ortho‐acylmethylaryl)‐2,3‐dihydrophthalazine‐1,4‐diones were used as potential starting materials for the expeditious synthesis of 6‐arylphthalazino[2,3‐a]cinnoline‐8,13‐diones and 5‐acyl‐5,6‐dihydrophthalazino[2,3‐a]cinnoline‐8,13‐diones under Lawesson's reagent and BF3⋅OEt2 mediated conditions, respectively. Of these, the BF3⋅OEt2‐mediated cyclization proceeded in DMSO as a solvent and a methylene source via dual C−C and C−N bond formations.
Dynamic Functional Connectivity Reveals Abnormal Variability and Hyper‐connected Pattern in Autism Spectrum Disorder

Published: October 2019

Autism spectrum disorder (ASD) is a general neurodevelopmental disorder associated with altered brain connectivity. However, most connectivity analyses in ASD focus on static functional connectivity, largely neglecting brain activity dynamics that have been reported to provide deeper insight into the underlying mechanisms of brain functions. Therefore, we anticipate that the use of dynamic functional connectivity (DFC) with interaction of clustering measures could help characterize ASD severity and reveal more information. In this study, we applied the sliding‐window and k‐means clustering methods to perform DFC and clustering analyses in ASD and typically developing (TD) groups. Data from 62 ASD and 63 TD children were acquired from the open‐access data set Autism Brain Imaging Data Exchange. Our findings revealed higher DFC variability between the posterior cingulate gyrus (PCC) and middle temporal pole (TPOmid) in subjects with ASD. The connection between the PCC and pars opercularis of inferior frontal gyrus (IFGoper) also presented greater variability in ASD, with the increase depending on ASD symptom severity. Furthermore, clustering analysis showed higher averaged dwell time and probability of transition for globally hyper‐connected state in the ASD group, which could be related to connection variability between the PCC and IFGoper. Our results demonstrate that both the PCC and IFGoper play crucial roles in characterizing symptom severity and state configuration in ASD, and brain connectivity dynamics may serve as potential indicators of ASD in future studies. Autism Res 2020, 13: 230–243. © 2019 International Society for Autism Research, Wiley Periodicals, Inc.Lay SummaryDynamic functional connectivity (DFC) refers to functional connectivity that changes over a short time. This study found that DFC instability between the posterior cingulate gyrus and pars opercularis of inferior frontal gyrus is associated with abnormal brain pattern configurations and dysfunction of social cognitive processes in autism spectrum disorder (ASD). These findings could contribute to a deeper understanding of the neural mechanisms of ASD and help characterize ASD severity.
