The effect of edge activator on the evolution and application of a nonionic surfactant: The elastic vesicular system
Authors: Sarolia Jayant , Baldha Raj , Chakraborthy G. S. , Rathod Sachin 
Published: June 2023

AbstractVesicular drug delivery as part of the colloidal system was evolved to entrap a hydrophobic drug as well as a hydrophilic drug. The tremendous potential of this system lies in ensuring the targeted and controlled release of the drug molecules to reduce the toxicity and side effects. Liposomes and niosomes are the first duos of the vesicular system to be used in the pharmaceutical and cosmetic fields. However, the lack of elasticity in this formulation prevents its success on the market. To overcome the obstacles, additional formulation changes were made to the existing vesicle. These modifications were attributed to the one component termed edge activator (EA), which added an elasticity factor to the vesicle system. Based on the formulation and EA, the vesicular system transits in the liposome to the spanlastic system. Spanlastics are surfactant‐based nanovesicles that are elastic, malleable, and given that it is a vesicular system with polar and nonpolar components, it can retain both hydrophilic and lipophilic medications. A modified method of medication delivery may also be possible. This review article discusses the recent approaches to the evolution of nonionic surfactant vesicular systems with respect to their method of preparation, effects of EA, and therapeutic application of spanlastic.

AbstractPrimary squamous cell carcinoma (SCC) of the breast is rare, representing less than 0.1% of all breast cancers. To date, there have been 20 reported cases of SCC associated with breast augmentation, usually in patients with long‐standing implants. A patient is reported here with primary squamous carcinoma of the breast associated with textured saline implants. Due to the paucity of cases, there is limited information on the incidence and management of implant‐associated SCC of the breast.

Published: June 2023

AbstractThe study was conducted to investigate the in vitro gas production characteristics and methane (CH4) emission potential of indigenous legume fodder trees and shrubs (ILFTS). The most predominant 11 ILFTS species were selected, and leaves and fruit/pod samples were collected, oven dried, and ground. The potential leaf biomass yield (PBY), dry matter (DM), ether extract, digestible crude protein, carbohydrate (CHO), acid detergent lignin, ash, total phenol, condensed tannin, gross energy, digestible energy, metabolizable energy (ME), gas production characteristics, CH4 emissions, organic matter digestibility (OMD), and short‐chain fatty acids (SCFA) were determined. ANOVA and independent t test were used to examine variation among species in plants nature and between fruits and pods within agroecosystems, respectively. Correlation analysis was used to determine relationships among parameters. The study indicated that only DM and CHO showed substantial variation in nutritional quality parameters among trees, shrubs, and fruit/pods in the lowlands. Fruits/pods and trees displayed significant differences in gas production characteristics in the lowlands, unlike shrubs, which had non‐substantial variations. Moreover, the PBY, CH4 emission, OMD, and ME of ILFTS revealed substantial variation (P < .05) with species and among trees, shrubs, and fruits/pods in both agroecosystems. Besides, CH4 production showed a positive significant correlation with gas volume and (b) substantiating the effect of rate and degree of fiber fermentation on CH4 emission. It was discovered that there was a positive significant correlation between the 6 and 24 h incubation period, (c) which substantiated the need for optimal microbial density and substrate for high rate constant gas production of b (c). In conclusion, ILFTS produce considerable biomass rich in nutrients but vary in the degradability of CHO with plant nature, species, and forage origin. This elicits differences in gas production characteristics and CH4 emission with in vitro fermentation, resulting in differences in the corresponding OMD, ME, and SCFA values.
Dissolved organic carbon export in a small, disturbed peat catchment: Insights from long‐term, high‐resolution, sensor‐based monitoring
Authors: Bass Adrian M. , Coleman Martin , Waldron Susan , Scott Marian 
Published: June 2023

AbstractUnderstanding dissolved organic carbon (DOC) export dynamics from carbon‐rich environments is critical. Peatlands act as terrestrial carbon stores, and consequently supply substantial amounts of DOC to drainage. This DOC flux is temporally heterogeneous and subject to long‐ and short‐term variability. Ultrahigh temporal resolution sampling (< hourly) is still in‐frequent in peatland catchments. We used a field‐deployable —ultraviolet–visible light spectrometer (Spectro::lyser™) and monitored DOC flux from a temperate peatland over 31 months to examine seasonal and event dynamics. DOC concentration varied from 6.8 to 63.5 mg L−1, in the higher reported range for peatlands and showed clear seasonal (high‐summer, low‐winter) variability coinciding with elevated biological productivity in the peatland. Discharge was an unreliable predictor of instantaneous DOC concentration overall, with antecedent water temperatures proving the most reliable predictor overall. Discharge drove total DOC export in the catchment, where the top 10% of flow events, accounted for 41.3% of all DOC exported—increasing to 84.6% in the top 50% of flow events. Total estimated catchment DOC flux was sensitive to measurement frequency: increasing from every 30 min to daily altered export estimates by < 1%, increasing to > 10% at 1‐week intervals. The variation in estimated flux increased approximately linearly with reduced sampling frequency, reaching > 40% at monthly intervals. High‐resolution data reveal the large amount of within‐site complexity of DOC export dynamics in a temperate peatland and provide evidence on the subsequently recommended sampling frequency for the future elucidation of detailed DOC budgets in these environments.
THE CASE FOR LEADER MORALITY
Authors: Gist Marilyn , Mulally Alan 
Published: June 2023

AbstractThe authors contend that in a world of great change and ever‐increasing tough problems, leaders must factor in the topic of morality as they work and make decisions. Gist is a former academic at the University of Washington and Seattle University; and Mulally is the former CEO of Boeing Commercial Airplanes and Ford Motor Company. They point to the need of morality as “virtues an individual has that guide how he or she actually determines what is the right thing to do and behaves accordingly.” They amplify that “In essence, morality refers to human judgment that some things are right while others are wrong, and that social standards or norms exist to distinguish and guide those determinations.” They draw on examples of morality‐deficient decisions by some pharmaceutical executives and the relation to opiate addiction; and social media company executives who prioritize content that leads to the most “engagement.” Unfortunately, this engagement can become inflammatory. The resulting “negative impact on society includes increasing political polarization, escalating racism, and growing violence.” The authors discuss Gist’s concept of Leader Humility, which “drives the moral virtues of honesty and courage.” Within that is the concept of self‐honesty: “It takes confidence to review one’s behavior, acknowledge weaknesses, mistakes, and personal motives.”
WE HAVE TO DEVELOP LEADERS’ ABILITY TO RESONATE
Authors: Winkler Ingo , Pelzmann Sabine 
Published: June 2023

AbstractThe authors write about “leaders’ ability to resonate with the organization and the broader social and environmental system.” Winkler, an academic, and Pelzmann, an organizational coach, explain that “to resonate means relating to the social, material and natural world in responsive and dialogical ways.” They write that their “argument broadly follows the ideas of the German sociologist Hartmut Rosa, who engages in critical sociological analysis of late modernity. Among other things, he is known for his work on social acceleration in modern societies.” Regarding leadership training, the authors cite the late Bruno Latour, who “claims that humans must return to the awareness that they coexist with nature, and they must comprehend that they are a part of nature and not nature's conqueror.” Also referenced is C. Otto Scharmer, author of Theory U: Leading from the Future as it Emerges, who believes that “when operating from that deeper stage of conversation, we begin to act as elements of a whole that is larger than our self.” Following the reasoning of these theorists, the authors explain six types of leadership capabilities, which in their words are: Personal, Methodological, Leadership, Cooperation, Self‐Care, and Transformational.
Dynamics Responses of Graphene Nanoplatelets‐Reinforced Polydimethylsiloxane Nanocomposites: A Molecular Dynamics Study
Authors: Li Zheng , Li Tong , Zhang Ke , Wang Bo 
Published: June 2023

AbstractMolecular dynamics method is employed to characterize the mechanical properties of polydimethylsiloxane (PDMS) materials reinforced by graphene nanoplatelets (GNPs). Modeling results demonstrate that the addition of GNPs to PDMS significantly improves the damping properties of PDMS at high temperatures. The underlying physical mechanism is further investigated, and it is found that the interfacial interactions between the GNPs and PDMS play a crucial role in the energy dissipation capabilities. At elevated temperatures, a decrease in the interaction energy between the GNPs and PDMS matrix is observed, increasing the interfacial shipment, and improving the energy dissipation. In addition, GNPs will reflect more impact energy at a higher temperature. This study provides valuable insights into the use of GNPs for the improvement of the damping performance of PDMS materials at high temperatures.

Published: June 2023

AbstractA high‐performance dual‐polarized horn antenna for a 5G millimeter wave compact antenna test range system (CATR) is proposed in this article. The feed antenna is mainly composed of a double‐ridged waveguide junction orthomode transducer (OMT), mode converter, and corrugated horn antenna. Among them, the OMT is the key device for the feed antenna to achieve dual polarization characteristics, and adopts a modular design method to apply the multi‐section impedance transformer in the vertical and horizontal polarization channels with good transmission characteristics. The corrugated horn antenna generates a symmetrical radiation pattern mainly in six corrugated slots. The proposed dual‐polarized corrugated horn antenna impedance matching bandwidth (VSWR < 2) is 24–50 GHz. Moreover, the measured gain is 10–12 dBi, and the measured cross‐polarization level is less than −30 dB within the operating frequency range. Meanwhile, the half‐power beamwidth radiation pattern in the whole operating band has a good symmetry and the beamwidth in both E‐ and H‐plane remains stable. As a practical application, the designed antenna is used as the feed of the CATR system. The measured results show that the amplitude distribution in the quiet zone (QZ) is within ±1 dB, the phase distribution is within ±8°, and the cross‐polarization isolation is better than 27 dB. The performance of the QZ is conducive to the use of the CATR system.

Published: June 2023

AbstractComposite of reduced graphene oxide (rGO) and polyaniline (PANI) have gained much attention in industrial applications especially for the fabrication of supercapacitor and flexible sensors. Nevertheless, existing studies mainly focus on the application efficiency and are lacking information on how morphology of the nanoparticles can affect the electrode properties. Herein, the effects of shape of PANI on the electrode resistivity were systematically investigated. PANI of different shapes was synthesized using different reagents, namely H2SO4, CH3COOH, H2O, and NH3·H2O, which induced formation of globule, tube, plate, and flake‐like PANI. rGO‐PANI composite was then produced using ex situ method and cast on a PVC substrate to form a flexible electrode. The rGO‐PANI globules displayed superior electrical conductivity owing to its high protonation level. The resistivity of this sample was found to be 0.015 ± 0.002 Ωcm, which is lowest as compared to the counterparts. Interestingly, electrode made of rGO‐PANI plates had a slightly lower electrical resistivity than rGO‐PANI tubes despite its low protonation level. It is speculate that the aspect ratio characteristic of the PANI might have influence the electron mobility. rGO‐PANI electrode was found to exhibit a lower specific resistivity than pure rGO and pure PANI, evincing the presence of synergism.

Published: June 2023

AbstractT263P mutation is one of the rare EGFR mutations located on chromosome 7p11.2, which is a change in amino acid residue at position 263 of the epidermal growth factor receptor protein, where L‐threonine has been replaced by L‐proline. This missense mutation in the extracellular EGFR domain is not well‐known in lung cancer. In this study, we first report a patient with advanced lung adenocarcinoma harbouring only a rare T263P EGFR mutation who benefited from first‐line afatinib therapy in Vietnam. The patient achieved a partial response with a time‐to‐treatment failure of 5 months. The patient subsequently received several chemotherapy regimens as the disease progressed, with overall survival of 17 months. Non‐small cell lung cancer with a rare T263P EGFR mutation responds to afatinib but has a poor prognosis. Further studies are needed to determine the efficacy of targeted therapies in this specific population.

Published: June 2023

AbstractIn the present study, regenerated cellulose fibres are functionalized with hydrolysed collagen from marine and bovine sources by surface treatment approach. A comparative study of collagen source is undertaken for the first time. Collagen infused fibres are subjected to various characterization like Fourier transform Infrared spectroscopy, X‐ray diffraction, Scanning electron microscopy, Thermogravimetric analysis, Nitrogen estimation, water holding capacity studies and antistatic measurements. Performance studies were also undertaken to evaluate their benefits. Marine collagen obtained from bones, with lower loading (∼2 wt %) is found to be optimum. Collagen infusion renders significant improvement in ultraviolet protection factor, antistaticity and water holding capacity which makes the material a sustainable and premium choice for functional textiles. Evaluation of the fabric properties reveals an enhancement in shelf life and freshness of commodities. Usage of collagen, obtained from aquaculture/animal waste exhibits the potential of waste valorisation for textiles. The biodegradability of the product conforms to the green sustainable initiative. Conclusively, collagen modified viscose fibres provides a new direction for future technological development in the textile industry encompassing sustainable benefits.
Imine‐Linked Porous Organic Polymer Gel and Immobilization of Copper(II): Easy Synthesis and Excellent Catalyst for Huisgen [3+2] Cycloaddition Reactions
Authors: Joseph Pradeepruban , Kundu Pintu K. 
Published: June 2023

AbstractPorous organic polymeric gels (POP gels) were made by condensation of a newly synthesized C3‐symmetrical azobenzene‐based tri‐salicylaldehyde building block, 1,3,5‐tris(4‐((3‐formyl‐4‐hydroxyphenyl)diazenyl)phenyl)benzene (TAzo) with suitable aromatic tri‐ and di‐amines in N,N‐dimethylformamide (DMF) at ambient conditions. Here, we have furnished the pathway of an efficient, gentle, and simple one‐pot synthesis of imine‐linked porous organic polymers at room temperature without any acid catalysts. Detail rheological properties of the POP‐gels were studied and were also found to be stable for at least a year at room temperature. Nitrogen isotherm revealed the mesoporous nature of the gel‐powders with moderate surface area. Iminophenol moieties are known to provide binding sites to metallic species via the strong coordination interaction with hydroxy (−OH) and imine (−HC=N−) groups. We have successfully synthesized a copper‐metallated POP by immobilizing copper ions in one of the POP‐gels. The mesoporous POP material having 3 wt % copper loading was utilized for the solvent‐free Huisgen [3+2] cycloaddition reactions of various aryl, benzyl, and alkyl azides with terminal alkynes containing aromatic, heteroaromatic, and alkyl groups with excellent yield. The heterogeneous catalyst with low catalyst loading (1 mol %) was highly regioselective towards 1,4‐disubstituted 1,2,3‐triazoles, recyclable, and did not require the addition of a reducing agent.

AbstractUnderstanding electron irradiation effects is vital not only for reliable transmission electron microscopy characterization, but increasingly also for the controlled manipulation of 2D materials. The displacement cross sections of monolayer hexagonal boron nitride (hBN) are measured using aberration‐corrected scanning transmission electron microscopy in near ultra‐high vacuum at primary beam energies between 50 and 90 keV. Damage rates below 80 keV are up to three orders of magnitude lower than previously measured at edges under poorer residual vacuum conditions, where chemical etching appears to dominate. Notably, it is possible to create single vacancies in hBN using electron irradiation, with boron almost twice as likely as nitrogen to be ejected below 80 keV. Moreover, any damage at such low energies cannot be explained by elastic knock‐on, even when accounting for the vibrations of the atoms. A theoretical description is developed to account for the lowering of the displacement threshold due to valence ionization resulting from inelastic scattering of probe electrons, modeled using charge‐constrained density functional theory molecular dynamics. Although significant reductions are found depending on the constrained charge, quantitative predictions for realistic ionization states are currently not possible. Nonetheless, there is potential for defect‐engineering of hBN at the level of single vacancies using electron irradiation.
Modulation of p‐ and n‐Type Transitions in Co3−xNixO4Nanoparticles for Enhanced Supercapacitor Electrochemical Performance

Published: June 2023

AbstractThe efficient storage of electrons and the type of conduction in semiconductor materials are important factors in determining their electrochemical performance. However, the interaction between these two factors is often overlooked by researchers. In this study, the effects of Ni doping at Co3−xNixO4nanoparticles on the electronic storage form of the material and resulting changes in the conduction p/n‐type are reported. Theoretical calculations demonstrate that n‐type conduction with high effective mass of electrons contributes significantly to the redox reaction of electrode materials and is beneficial for improving electrochemical performance. The specific capacitance of Co3−xNixO4(x = 0.67) electrode material is 10 times larger than that of Co3O4due to enhanced orbital hybridization caused by Ni atom doping. The findings provide new directions for exploring the mechanism of conductive type conversion of materials and offer insights beyond the traditional approach of considering doping content alone.
Precise Defect Engineering on Graphitic Carbon Nitrides for Boosted Solar H2 Production

Published: June 2023

AbstractDefect engineering has been regarded as an “all‐in‐one strategy” to alleviate the insufficient solar utilization in g‐C3N4. However, without appropriate modification, the defect benefits will be partly offset due to the formation of deep localized defect states and deteriorated surface states, lowering the photocarrier separation efficiency. To this end, the defective g‐C3N4 is designed with both S dopants and N vacancies via a dual‐solvent‐assisted synthetic approach. The precise defect control is realized by the addition of ethylene glycol (EG) into precursor formation and molten sulfur into the pyrolysis process, which simultaneously induced g‐C3N4. with shallow defect states. These shallow defect energy levels can act as a temporary electron reservoir, which are critical to evoke the migrated electrons from CB with a moderate trapping ability, thus suppressing the bulky photocarrier recombination. Additionally, the optimized surface states of DCN‐ES are also demonstrated by the highest electron‐trapping resistance (Rtrapping) of 9.56 × 103 Ω cm2 and the slowest decay kinetics of surface carriers (0.057 s−1), which guaranteed the smooth surface charge transfer rather than being the recombination sites. As a result, DCN‐ES exhibited a superior H2 evolution rate of 4219.9 µmol g−1 h−1, which is 29.1‐fold higher than unmodified g‐C3N4.
