Employing Redox‐Active Additives for Enhanced Charge Polarization and Twofold Higher Energy Density in Supercapacitor
Authors: Nandi Poulomi , Subramaniam Chandramouli 
Published: February 2023

AbstractRemarkable improvement in the polarization and charge transport at the solid–solid electrode–electrolyte interface due to the incorporation of a redox‐active additive sodium molybdate (Na2MoO4) is demonstrated. The presence of the electrochemically active oxide center along with Na+facilitates the hopping‐based charge transport of the ionic liquid leading to higher ionic conductivity and a twofold increase in specific capacitance (0.009 to 0.018 F cm−2). This drives a 200% increase in the energy density (0.76–1.7 µW h cm−2) and a 2.5 times improvement in the rate capability (10 000 mV s−1) of the solid‐state supercapacitor. Importantly, the power density, non‐Faradic nature, and cyclability remain unaltered, resulting in performance exceeding several solid‐state and liquid electrolyte‐based supercapacitors. Thus, the results established here through the use of redox‐active additive establish the robustness of the approach and practicality of the resulting device besides providing transformative opportunities in tuning the performance of solid‐state devices.

AbstractThe ability to modulate the nonlinear optical (NLO) response of low‐dimensional metal oxides is highly desirable for diverse applications. It is shown here that the irradiation of a dispersion of 2D oxide (MoO3) nanosheets (NSs) by femtosecond laser pulses enables simultaneous scissoring of the NSs to form well‐dispersed MoO3 quantum dots (QDs) and the modulation of the NLO response in the visible and near‐infrared (NIR) regions. The inversion of the absorptive nonlinearity is observed combined with a larger enhancement of NLO response in the laser‐irradiated MoO3−x NSs and the as‐generated QDs, which is associated with the steady laser‐deprival of oxygen atoms and the resultant localized surface plasmon resonance due to electron doping. By leveraging the sub‐picosecond NLO response of the plasmonic MoO3−x QDs, the development of ultrafast optical switches is demonstrated for ultrashort pulse laser generation based on fiber lasers operating in the NIR regions. Furthermore, the strong field enhancement of these non‐noble metal plasmonic QDs is exploited for the fabrication of substrates for surface‐enhanced Raman scattering, which demonstrate a detection limit down to the part‐per‐billion level. This work delineates an efficient strategy for creating plasmonic oxide QDs with strong NLO response that is attractive for photonic applications.

AbstractChanges in gene expression in lung epithelial cells are detected in cancer tissues during exposure to pollutants, highlighting the importance of gene‐environmental interactions in disease. Here, a Cd‐induced malignant transformation model in mouse lungs and bronchial epithelial cell lines is constructed, and differences in the expression of non‐coding circRNAs are analyzed. The migratory and invasive abilities of Cd‐transformed cells are suppressed by circCIMT. A significant DNA damage response is observed after exposure to Cd, which increased further following circCIMT‐interference. It is found that APEX1 is significantly down‐regulated following Cd exposure. Furthermore, it is demonstrated that circCIMT bound to APEX1 during Cd exposure to mediate the DNA base excision repair (BER) pathway, thereby reducing DNA damage. In addition, simultaneous knockdown of both circCIMT and APEX1 promotes the expression of cancer‐related genes and malignant transformation after long‐term Cd exposure. Overall, these findings emphasis the importance of genetic‐epigenetic interactions in chemical‐induced cancer transformation.

Published: February 2023

AbstractSingle‐wall carbon nanotube/silicon (SWCNT/Si) heterojunction shows appealing potential for use in photovoltaic devices. However, the relatively low conductivity of SWCNT network and interfacial recombination of carriers have limited their photovoltaic performance. Herein, a multifunctional Lewis acid (p‐toluenesulfonic acid, TsOH) is used to significantly reduce the energy loss in SWCNT/Si solar cells. Owing to the charge transfer doping effect of TsOH, the conductivity and work function of SWCNT films are optimized and tuned. More importantly, a chemical bridge is constructed at the interface of SWCNT/Si heterojunction. Experimental studies indicate that the phenyl group of TsOH can interact with SWCNTs through π–π interaction, meanwhile, the oxygen in the sulfonic functional group of the TsOH molecule can graft on the dangling bonds of the Si surface. The chemical bridge structure effectively suppresses the recombination of photogenerated carriers. The TsOH coating also works as an antireflection layer, leading to a 19% increment of the photocurrent. As a result, a champion power conversion efficiency of 17.7% is achieved for the TsOH‐SWCNT/Si device, and it also exhibits an excellent stability, retaining more than 96% of the initial efficiency in the ambient air after 1 month.

Published: February 2023

AbstractCrystallinity of π‐conjugated polymer donors as well as acceptors is a crucial factor for boosting the performance of organic photovoltaic (OPV) cells. However, in the state‐of‐the‐art OPVs based on nonfullerene acceptors (NFAs), π‐conjugated polymers with low crystallinity are typically used and provide high efficiencies. Here, π‐conjugated polymers, named PTzBT and PTzBTE based on thiazolothiazole (TzTz), having similar crystallinity but different aggregation properties are blended with a number of acceptor materials such as PC71BM, IT‐4F, Y6, and Y12 having different aggregation property. Interestingly, whereas PTzBTE with higher aggregation properties forms crystalline structures in the blends regardless of the acceptor material, PTzBT with lower aggregation properties exhibits crystalline structures only when blended with acceptors having higher aggregation properties. Notably, the crystalline order of the materials in the blend films is correlated closely with the OPV performance. This study proposes that the interplay between the polymer donor and acceptor will play a crucial role in determining the crystalline order in the bulk heterojunction systems and thereby high photovoltaic performance.

AbstractMyeloproliferative neoplasms (MPN) are characterized by uncontrolled expansion of myeloid cells, disease‐related mutations in certain driver‐genes including JAK2, CALR, and MPL, and a substantial risk to progress to secondary acute myeloid leukemia (sAML). Although behaving as stem cell neoplasms, little is known about disease‐initiating stem cells in MPN. We established the phenotype of putative CD34+/CD38− stem cells and CD34+/CD38+ progenitor cells in MPN. A total of 111 patients with MPN suffering from polycythemia vera, essential thrombocythemia, or primary myelofibrosis (PMF) were examined. In almost all patients tested, CD34+/CD38− stem cells expressed CD33, CD44, CD47, CD52, CD97, CD99, CD105, CD117, CD123, CD133, CD184, CD243, and CD274 (PD‐L1). In patients with PMF, MPN stem cells often expressed CD25 and sometimes also CD26 in an aberrant manner. MPN stem cells did not exhibit substantial amounts of CD90, CD273 (PD‐L2), CD279 (PD‐1), CD366 (TIM‐3), CD371 (CLL‐1), or IL‐1RAP. The phenotype of CD34+/CD38− stem cells did not change profoundly during progression to sAML. The disease‐initiating capacity of putative MPN stem cells was confirmed in NSGS mice. Whereas CD34+/CD38− MPN cells engrafted in NSGS mice, no substantial engraftment was produced by CD34+/CD38+ or CD34− cells. The JAK2‐targeting drug fedratinib and the BRD4 degrader dBET6 induced apoptosis and suppressed proliferation in MPN stem cells. Together, MPN stem cells display a unique phenotype, including cytokine receptors, immune checkpoint molecules, and other clinically relevant target antigens. Phenotypic characterization of neoplastic stem cells in MPN and sAML should facilitate their enrichment and the development of stem cell‐eradicating (curative) therapies.
Evolutionary biological perspectives on current social issues of breastfeeding and weaning
Authors: Tsutaya Takumi , Mizushima Nozomi 
Published: February 2023

AbstractBreastfeeding and weaning are actively studied from evolutionary, medical, and social research perspectives because of their close association with infant mortality, lifetime health, and human population dynamics. Each discipline benefits from an interdisciplinary exchange of knowledge regarding the bases, processes, and consequences of these phenomena. However, current social issues related to breastfeeding and weaning have received little attention from an evolutionary biology perspective. We address this gap by reviewing current social issues related to human breastfeeding and weaning in an evolutionary framework. This approach helps build a conceptual framework with the goal of better understanding ultimate causes of or influences on these current social issues. The six social issues reviewed here fall into three categories: the spatiotemporal constraints of breastfeeding, abuse of breast milk as valuable material, and mismatch in breastfeeding practices. Some of these issues have an evolutionary basis. We analyze the structure of these social issues and discuss their possible solutions in terms of extension of the trade‐off theory in evolutionary biology. Our discussion on the current social issues in breastfeeding and weaning highlights the effectiveness of an approach rooted in evolutionary theory and biological anthropology.

Non‐Random Island Nucleation in the Electrochemical Roughening on Pt(111)

Published: February 2023

AbstractMany chemical surface systems develop ordered nano‐islands during repeated reaction and restoration. Platinum is used in electrochemical energy applications, like fuel cells and electrolysers, although it is scarce, expensive, and degrades. During oxidation‐reduction cycles, simulating device operation, nucleation and growth of nano‐islands occurs that eventually enhances the dissolution. Preventing nucleation would be the most effective solution. However, little is known about the atomic details of the nucleation; a process almost impossible to observe. Here, we analyze the nuclei‐distance distribution mapping out the underlying atomic mechanism: a rarely observed, non‐random nucleation takes place. Special, preferential nucleation sites that a priori do not exist, develop initially via a precursor and eventually form a semi‐ordered Pt‐oxide structure. This precursor mechanism seems to be general, possibly explaining also the nano‐island formation on other surfaces/reactions.

AbstractAdjuvants stimulate the immune system to vigorously respond to a vaccine. While current adjuvants such as aluminum salts and oil‐in‐water emulsions have been used for decades, they do not generate broad and long‐lasting responses in many vaccines. Consequently, more potent adjuvants are needed. Here, using computer‐aided molecule design and machine learning, we discovered 2 new, broad‐spectrum adjuvants that can boost vaccine responses. Our library containing 46 toll‐like receptor (TLR)‐targeting agonist ligands were assembled on Au nanoparticles. Comprehensive in vitro, ex vivo and in vivo studies showed both leads promoted dendritic cell activation via multiple TLRs and enhanced antigen presentation to T cells. When used together with tumor‐specific antigens to immunize mice against B16‐OVA melanoma and 4T1‐PD1 breast cancer, both adjuvants unleashed strong immune responses that suppressed tumor growth and lung metastases. Our results show computer‐aided design and screening can rapidly uncover potent adjuvants for tackling waning immunity in current vaccines.

AbstractA double‐walled tetrahedral metal‐organic cage assembled in solution from silver(I), 2‐formyl‐1,8‐naphthyridine, halide, and a threefold‐symmetric triamine. The AgI4X clusters at its vertices each bring together six naphthyridine‐imine moieties, leading to a structure in which eight tritopic ligands bridge four clusters in an (AgI4X)4L8 arrangement. Four ligands form an inner set of tetrahedron walls that are surrounded by the outer four. The cage has significant interior volume, and was observed to bind anionic guests. The structure also possesses external binding clefts, located at the edges of the cage, which bound small aromatic guests. Halide ions bound to the silver clusters were observed to exchange in a well‐defined hierarchy, allowing modulation of the cavity volume. The principles uncovered here may allow for increasingly more sophisticated cages with silver‐cluster vertex architectures, with post‐assembly tuning of the interior cavity volume enabling targeted binding behavior.

AbstractWith a theoretical capacity of 847 mAh g−1, Sn has emerged as promising anode material for sodium‐ion batteries (SIBs). However, enormous volume expansion and agglomeration of nano Sn lead to low Coulombic efficiency and poor cycling stability. Herein, an intermetallic FeSn2 layer is designed via thermal reduction of polymer‐Fe2O3 coated hollow SnO2 spheres to construct a yolk‐shell structured Sn/FeSn2@C. The FeSn2 layer can relieve internal stress, avoid the agglomeration of Sn to accelerate the Na+ transport, and enable fast electronic conduction, which endows quick electrochemical dynamics and long‐term stability. As a result, the Sn/FeSn2@C anode exhibits high initial Coulombic efficiency (ICE=93.8 %) and a high reversible capacity of 409 mAh g−1 at 1 A g−1 after 1500 cycles, corresponding to an 80 % capacity retention. In addition, NVP//Sn/FeSn2@C sodium‐ion full cell shows outstanding cycle stability (capacity retaining rate of 89.7 % after 200 cycles at 1 C).

Published: February 2023

AbstractDegradable membranes were obtained by blending of polyvinyl chloride (PVC) with poly lactic acid (PLA) as biodegradable polymer. The effect of the amount of PLA from 10 to 30 wt% on the PVC membrane properties was investigated. The PVC/PLA(80/20) membrane exhibited higher porosity, water uptake and pure water flux than other fabricated membranes. The PVC/PLA(80/20) membrane in TGA results showed that lower temperature required to decompose the membrane in compare of neat PVC membrane. The effect of the amount of hydroxyapatite (HAp) from 0.0 to 3.0 wt% on the PVC/PLA(80/20) membrane structural and antifouling properties was investigated. With the increase in the amount of the HAp up to 2.5 wt%, membrane porosity, hydrophilicity and pure water flux increased. PVC/PLA(80/20)‐2.5 membrane showed higher surface roughness in compare of neat PVC and PVC/PLA(80/20) blended membrane, resulting in higher antifouling properties. Also in the SEM images, embedding the HAp causes to suppress the macrovoids in the cross section of membrane with a higher number of surface pores, which also had lower pore diameter.The humic acid rejection ratios of all PVC/PLA‐HAp nanocomposite membranes were higher than 87%; and all the nanocomposite membranes exhibited higher reversible fouling ratios (RFRs) than the neat PVC membrane.
Improved interfacial shear strength in carbon fiber/polyamide 6 composite via a novel two‐component waterborne polyurethane sizing agent

Published: February 2023

AbstractThe rise of continuous carbon fiber (CF) reinforced polyamide 6 (PA6) composites has put forward higher requirements for the tailoring of thermoplastic composite interphase. In this work, a novel two‐component waterborne polyurethane (WPU) sizing agent was prepared to improve the interfacial strength of CF/PA6 composite. One of the components was carboxyl terminated polyurethane, the other one was blocked isocyanate. Both of the components were designed to react with the CF surface, as well as the matrix resin during composite fabrication. This sizing agent with excellent storage stability was homogeneously coated on CF surface, introducing abundant reactive groups and improving the CF surface energy remarkably. A linear regression method was applied to determine the interfacial shear strength (IFSS) from the micro‐droplet test. Results showed that the IFSS of the WPU sized CF increased to 51.8 MPa, which was 22% and 47% higher than that of the unsized and epoxy‐compatible sized CF, respectively. That value was also higher than that of the same materials reported in literature. This sizing agent provides a promising method for improving the interfacial strength of thermoplastic composites.
Theories and implications for centering Indigenous and queer embodiment within sociotechnical systems
Authors: Wagner Travis L. , Marsh Diana , Curliss Lydia 
Published: February 2023

AbstractThis paper explores the role of Indigenous and queer embodiment in understanding the current limitations of sociotechnical systems as they relate to cultural heritage institutions. Through the utilization of a critical case study the paper highlights the ways in which the ideologies of colonialism and cisnormativity render Indigenous and queer identities invisible within cultural heritage institutions. In particular, the case studies highlight information organization, archival description, and cataloging as sites of ideological reinforcement for colonialism and gender binaries. In response, the paper identifies methods for not only naming such normative ideologies, but actionable ways to challenge such inequities through community‐led, Indigenous, and queer affirming descriptive practices. Additionally, the paper attends to the way findings impact other historically marginalized identities and theorize methods for confronting such inequities within sociotechnical systems more broadly.

AbstractDie Baustellenüberwachung ist heutzutage ein überwiegend manueller Prozess, bei dem die Ereignisse auf der Baustelle von Baustellenpersonal händisch dokumentiert werden. Diese ineffizienten, nicht mehr zeitgemäßen Arbeiten resultieren in einem erheblichen Zeit‐ und Kostenaufwand und einer hohen Fehleranfälligkeit. Demgegenüber bieten die rasanten Entwicklungen der Informationstechnik vielseitige Möglichkeiten, mit z. B. Bluetooth Low Energy (BLE) Monitoring, Kameras und Laserscannern Daten in Echtzeit zu erfassen und auszuwerten. Die Baustelle kann durch einen Digitalen Zwilling widergespiegelt werden, welcher die enormen Mengen an Rohdaten strukturiert abspeichert und verwaltet. Um aus der Masse an Rohdaten Informationen und Unternehmenswissen zu generieren, sind u. a. verschiedene AI‐gestützte Verarbeitungsmethoden notwendig. Das Potenzial, mithilfe dieser Informationen eine voll automatisierte Baustellenüberwachung umzusetzen, ist unbestreitbar. Eine präzise, maschinelle Erfassung von Eckdaten der Bauprozesse, wie Prozessbeginn, Prozessende und verwendete Ressourcen, wird zukünftig ein essenzielles Fundament zur Optimierung der Baustelle bilden. Der vorliegende Beitrag beleuchtet den aktuellen Stand der Technik im Bereich computergestützte Baustellenüberwachung und präsentiert darüber hinaus Erkenntnisse, die beim Monitoring von mehreren Baustellen gesammelt wurden.
