Published: July 2022

AbstractA novel strategy for robust and ultrathin (<1 µm) multilayered protective structures to address uncontrolled Lithium (Li) dendrite growth at Li‐metal battery anodes is reported. Synergetic interaction among Ag nanoparticles (Ag NPs), reduced graphene oxide (rGO) films, and self‐assembled block‐copolymer (BCP) layers enables effective suppression of dendritic Li growth. While Ag NP layer confines the growth of Li metal underneath the rGO layer, BCP layer facilitates the fast and uniformly distributed flux of Li‐ion transport and mechanically supports the rGO layer. Notably, highly aligned nanochannels with ≈15 nm diameter and ≈600 nm length scale interpenetrating within the BCP layer offer reversible well‐defined pathways for Li‐ion transport. Dramatic stress relaxation with the multilayered structure is confirmed via structural simulation considering the mechanical stress induced by filamentary‐growth of Li metal. Li‐metal anodes modified with the protective layer well‐maintain stable reaction interfaces with limited solid‐electrolyte interphase formation, yielding outstanding cycling stability and enhanced rate capability, as demonstrated by the full‐cells paired with high‐loading of LiFePO4 cathodes. The idealized design of multilayer protective layer provides significant insight for advanced Li‐metal anodes.

Published: July 2022

AbstractAn optic‐fiber sensor for detecting the concentration of trace copper ions is proposed using a ternary cross‐linked sensitive film coated on the Mach–Zehnder microfiber interferometer surface. The microfiber has a huge evanescent field offering high sensitivity to the ambient refractive index. The chelation between imidazole groups in the coated thin film and copper ions changes the refractive index of the sensor surface, which is converted into macroscopic wavelength drift in the interference spectrum. The sensitivity of the sensor is up to 7.715 × 106 nm M−1 with the detection limit of 0.0576 ppm. This sensor can effectively avoid the effect of temperature cross‐response and has good specificity and stability. This study has instructive meanings for designing optical pollutant sensors with high stability and improved detection accuracy in a potentially multi‐characteristic environment.

Published: July 2022

AbstractMetal halide perovskite materials have shown excellent optoelectronic properties suitable for light‐emitting diodes. With the development of technology in recent years, the performance of perovskite light‐emitting diodes (PeLEDs) has been improved rapidly, which can be almost comparable with that of the organic light‐emitting diodes (OLEDs) and quantum‐dot light‐emitting diodes counterparts. However, the toxicity of lead in perovskites may be unacceptable to consumers, which severely hinders the commercial applications of PeLEDs. Therefore, massive efforts on more environment‐friendly PeLEDs should be invested, prompting them potential candidates for next‐generation display devices. In this review, the synthesis methods and preparation processes of perovskite emitting layers that are successfully utilized in environment‐friendly PeLEDs are first summarized. Then, a comprehensive analysis of development on the applications of both less‐lead and lead‐free PeLEDs is reported. Finally, the possible strategies to further improve the performance of environment‐friendly PeLEDs are given.

AbstractAluminosilicate glasses offer wide‐ranging potential as enabling materials for a new generation of optical devices operating in harsh environments. In this work, a nonconventional manufacturing process, the molten core method, is employed to fabricate and study sapphire (Al2O3) and YAG (yttrium aluminum garnet) derived all‐glass silicate optical fibers in which a femtosecond (fs) laser is used to imprint oriented nanostructures inside the fiber cores. Both writing kinetics and thermal stability of the laser‐modified regions are investigated over a wide temperature range (20–1200 °C). The laser‐imprinted modifications in these high alumina‐content fibers exhibit improved thermal stability with respect to commercial pure silica and GeO2‐doped silica analogs. Furthermore, optical devices in the form of Rayleigh backscattering and fiber Bragg grating sensors are fabricated to demonstrate the high‐temperature sensitivity and stability of these nonconventional fibers. This functionalization of aluminosilicate fibers by fs‐laser direct writing opens the door to a new generation of optical devices suitable for high‐temperature operation.

Published: July 2022

AbstractCrude oil leakage is a security issue that needs to be avoided in many production areas such as oil fields and substations. However, crude oil leakage image data is often difficult to obtain due to security and privacy issues in the working area. And shadow interference is also a challenge for oil leakage detection tasks. This paper proposes a crude oil leakage detection method based on the DA‐SR framework. The framework consists of two parts: the data augmentation module and shadow removal module. High‐quality synthetic oil leakage images are generated using the cycle‐consistent adversarial networks (CycleGAN), and further process the synthetic images by a T‐CutMix sample processing method. To solve the problem of shadow interference, this paper uses the FlocalLoss function to calculate the confidence loss based on the YOLOv4 detection network and a hard sample retraining (HSR) algorithm to enhance the images with shadows. The experiments demonstrate that the combination of original and synthetic images when training the model can improve the performance of oil leakage detection. Finally, it is also shown that the detector built from the framework can effectively reduce the false detection of shadows.

Published: July 2022

AbstractThis 5‐yr study (2012–2017) aimed to evaluate the effects of sesbania (Sesbania rostrata Bremek. & Oberm) brown manure (SBM) and sorghum [Sorghum bicolor (L.) Moench] in rice (Oryza sativa L.)‐based rotations on weeds, soil properties, and rice yield. Four rice production systems were used: (a) wheat (Triticum aestivum L.)–rice (control), (b) wheat–rice + SBM, (c) wheat–sorghum–rice, and (d) wheat–sorghum–rice + SBM. Compared with control, allelochemicals accumulated in the rhizospheric soil of all other cropping systems over time and were the highest in the sorghum‐based rotations. Allelochemical accumulation in the soil reduced the densities and aboveground biomass of sedges and grassy and broad‐leaved weeds. Weed suppression was more evident when SBM in rice was included in the postsorghum field vs. the control. The use of SBM also enhanced soil organic matter (SOM), soil microbial biomass nitrogen (SMBN), and soil microbial biomass carbon (SMBC), and reduced the soil bulk density compared with the control. There was an improvement in SOM by 6.82, 0.57, and 9.09%, SMBC by 3.92, 0.86, and 6.29%, and SMBN by 3.12, 0.97, and 4.43% with wheat–rice + SBM, wheat–sorghum–rice, and wheat–sorghum–rice + SBM rotation, respectively, compared with the control. The highest paddy yield was recorded in the wheat–sorghum–rice–SBM, which was attributed to improved weed suppression in this system vs. wheat–rice rotation. The improved paddy yield in SBM‐based rotations was a direct outcome of better soil health and the built up of allelochemicals in the soil profile, which suppressed weeds and improved rice yield.

Published: July 2022

AbstractWe report the synthesis of cinchonine and hydrocinchonine derived surfactants by reacting with various mono alkylating agents (hexyl, octyl, octadecyl, dodecyl bromides) and di‐alkylating agent such as α,α’‐p‐xylene‐di‐bromide. A series of chiral surfactants have been used to stabilize palladium nanoparticles (NPs) which are water soluble. These Pd NPs were utilized in asymmetric Suzuki cross coupling reaction of naphthalene boronic acids with substituted naphthalene bromides to get binaphthalenes and terephenylenes. It was observed that, the surfactant's alkyl‐chain length and the palladium source played a major role in this catalytic reaction. The high solubility and positive zeta potential of gemini‐surfactant (GS) stabilized Pd NPs make them attractive as a potential candidate for the synthesis of binaphthalenes and terephenylenes with high yields.

AbstractMesoporous silica is a versatile material for energy, environmental, and medical applications. Here, for the first time, we report a flame aerosol synthesis method for a class of mesoporous silica with hollow structure and specific surface area exceeding 1000 m2 g−1. We show its superior performance in water purification, as a drug carrier, and in thermal insulation. Moreover, we propose a general route to produce mesoporous nanoshell‐supported nanocatalysts by in situ decoration with active nanoclusters, including noble metal (Pt/SiO2), transition metal (Ni/SiO2), metal oxide (CrO3/SiO2), and alumina support (Co/Al2O3). As a prototypical application, we perform dry reforming of methane using Ni/SiO2, achieving constant 97 % CH4 and CO2 conversions for more than 200 hours, dramatically outperforming an MCM‐41 supported Ni catalyst. This work provides a scalable strategy to produce mesoporous nanoshells and proposes an in situ functionalization mechanism to design and produce flexible catalysts for many reactions.
On‐Site Non‐enzymatic Orthogonal Activation of a Catalytic DNA Circuit for Self‐Reinforced In Vivo MicroRNA Imaging

Published: July 2022

AbstractThe wide extracellular‐intracellular distribution of microRNA requires the on‐site, robust and efficient activation of catalytic DNA circuits inside live cells. Herein, we develop an efficient non‐enzymatic circuitry activation strategy to realize the orthogonally controlled catalytic DNA (CCD) circuit for achieving high‐fidelity in vivo microRNA imaging through multiply guaranteed molecular recognition and progressively accelerated signal amplification. For predictable on‐site activation and useful catalytic efficiency, the dominating circuitry fuel strand was initially split into inactive fuel subunits that were grafted into an auxiliary catalytic circuit. There, the in‐cell‐specific mRNA triggered the orthogonal amplification of the active fuel strands for sensitive target detection through the chief entropy‐driven catalytic DNA circuit. We believe that the on‐site orthogonal circuitry activation method can contribute to clinical diagnosis and prognosis.

Published: July 2022

AbstractNew strategies are in high demand for fast, sensitive, selective, on‐site and real‐time detection of the important but challenging alkane vapors owing to their opto‐electronic inertness. Herein, we report, for the first time, a high‐performance fluorescent film sensor (FFS) for the alkanes with a rationally designed through‐space charge transfer (TSCT) molecule as the sensing fluorophore. Steady‐state fluorescence, femto‐second transient absorption spectroscopy and theoretical studies revealed continuous TSCT dynamics in the excited U‐shaped molecule with increasing medium polarity. Furthermore, the interlocked, face‐to‐face alignment between the donor and acceptor favors mass transport of the analyte molecules in the film state. As anticipated, the compound‐based FFS showed an experimental detection limit of ≈10 ppm forn‐pentane, less than 5 s for a full detection, negligible interference and super‐stability, revealing the effectiveness of the design strategy. Notably, the sensor is small (≈3.7 cm3), power‐saving, and workable at room temperature.

Published: July 2022

AbstractBiological membrane fluidity enables shape reform upon a functionally complementary encounter between a biomolecule and a synthetic nanoparticle. Nanomedicine uses ligand‐cell surface receptor affinities for nanoparticle targeting. However, due to toxicity concerns, the nature of the nanoparticle–biomembrane interaction needs exploration to realize ligand surface density and receptor–ligand interaction effects on subsequent uptake/other interaction outcomes. In this study, giant unilamellar vesicles (GUVs) were surface‐immobilized with a hCAII model receptor to study nanoparticle–complementary surface ligand interactions. We find interaction strength impacts morphological outcomes, namely, inter‐GUV adhesion, lysis, and GUV swallowing. Nanoparticle size, receptor/ligand surface densities, overall receptor/ligand concentrations and ratios affect the strength of adhesion, and thus the outcome. Interaction energy effects on GUV morphological outcomes offer fundamental insights into the design of abiological materials for interacting with biological materials.

Interactions of Selected Monoterpenes with Iron and Copper Ions Based on Ferrozine and CUPRAC Methods – the Preliminary Studies
Authors: Wojtunik‐Kulesza Karolina A. , Wiśniewska Renata 
Published: July 2022

AbstractSecondary plant metabolites are chemical compounds produced by plants through a variety of metabolic pathways. It is known that these compounds, among others, monoterpenes, are characterized by holding valuable pro‐health activities when consumed or applied. Taking into account the development of civilizational diseases, eating foods enriched with compounds such as the monoterpenes is highly recommended. Good sources of such health‐promoting food items include common fruits and vegetables, seed sources and plant parts used to enhance flavour such as spices. It is known that monoterpene compounds instigate or contribute to a variety of biological activities. It is known that the compounds can scavenge free radicals, reduce Fe(III) and inhibit AChE which are considered as possible anti‐neurodegenerative activities. The aim of the presented study was to determinate another activity of selected monoterpenes, namely towards reducing and chelating Cu(II) and Fe(II), respectively. The assays were based on colorimetric CUPRAC and ferrozine‐based methods. Study results explicitly indicated chelation and reduction activities of the selected monoterpenes. These properties considerably support the benefits of consuming plants rich in these compounds.
The Inner Hydration in Surfactant/Cholesterol Vesicles Differs from the Outer One: A Spectroscopic Investigation
Authors: Pyne Sumana , Pyne Partha , Kumar Mitra Rajib 
Published: July 2022

AbstractVesicles contain two aqueous regions: inner core and outer‐to‐bulk. It has remained an open question whether hydration behaviour in the inner core differs from the outer‐to‐bulk region, mostly owning to the inability of the conventional spectroscopic techniques to deconvolute the contribution from these two regions. We, using THz‐FTIR spectroscopy (1.5–13.5 THz) experimentally probe the inner hydration of three differently charged surfactant/cholesterol vesicles composed of SDS, CTAB and Brij 30. Both dynamic light scattering (DLS) and atomic force microscopy (AFM) measurements affirm the transition from micelles to vesicles as cholesterol is added into surfactant solutions. FTIR measurements show that hydration behaviour changes significantly as micelles are converted into vesicles, the change been exclusively caused due to the formation of an inner core. Our measurements on the hydrogen bond stretch and librational motion of the inner hydration show distinct features compared to the overall hydration, which in turn is found to be surfactant type and cholesterol concentration dependent.

Authors: Kankaala Taina , Kaakinen Pirjo , Anttonen Vuokko 
Published: July 2022

AbstractObjectivesPatient‐centered approach can offer valuable information in improving dental care, but literature is scarce. This study aimed to evaluate self‐reported factors beneficial for attendance in dental care.Material and MethodsSurvey data were collected during the summer of 2020 comprising both structured questionnaires and an open question on factors considered beneficial for dental attendance. Voluntary patients over 15 years of age (n = 196, 98%) agreed to fill the questionnaires, and n = 112 of them (57%) also gave open commentary in an urgent dental care clinic, City of Oulu, Finland, comprising the study population. Dental fear was assessed by Modified Dental Anxiety Scale (MDAS) sum scores (min 5, max 25). All utterances (n = 181) on an open question were evaluated by inductive content analysis to create sub‐ and main categories. Covid‐19 pandemic case counts in Finland were low at the time of the survey, but their effect on seeking dental care was asked. The distribution of patients was evaluated by cross‐tabulation, considering their age, gender, and dental fear status; the significance level was p < .05.ResultsFemales dominated slightly the study population (57%). The mean age of the respondents was 44 years. Half (50%) had moderate (MDAS score 10−18), and 10% had severe dental fear (≥19). The open responses could be categorized into four main categories. The largest main category by patient count concerned factors related to personnel (29%), followed by the patient (28%) and treatment (25%) related, and administrative factors (19%). Males chose factors falling into categories of administration and treatment while females chose patient and personnel‐related factors (p = .048). Compared to the rest, fearful persons (MDAS > 9) reported more often factors related to personnel and treatment (p = .03). Of all participants, 17% reported seeking less dental care during the pandemic.ConclusionsPatients value dental personnel and treatment‐related factors, specifically those with fear.
The impact of environmental disclosure on initial public offering underpricing: Sustainable development in Singapore
Authors: Kang Eugene , Lam Nguyen Bao 
Published: July 2022

AbstractThis study applies signaling theory to examine the impact of environmental disclosures on equity underpricing at initial public offerings (IPO) when private firms list on stock exchanges. Firms often under‐price their shares to attract investors as IPOs have high information asymmetry between firms and investors. Using a linguistic technique on environmental disclosures in prospectuses from 2009 to 2019 in the Singapore Exchange, we find that disclosures with a positive tone correlate with lower underpricing, but only if these disclosures are authentic. This finding is robust to different model specifications and measurements. We provide new evidence that linguistic features, that is, tone and authenticity, interact to influence a key IPO outcome. The results suggest that investors are not easily attracted by positive disclosure tones but are also concerned with the authenticity of such disclosures. This finding informs firms and various stakeholders navigating the nascent and growing wave of sustainability reporting in Singapore.
How might we co‐design energy transition policy in old industrial regions?
Authors: Sillak Silver , Vasser Madis 
Published: July 2022

AbstractThere has been growing interest in collaborative approaches such as co‐creation and co‐design for strategic energy planning and energy policy design. However, existing analyses have conceptualized collaboration in rather vague terms, have focused primarily on the involvement of industrial actors and have been set in Western Europe. In this paper, we assess an inclusive energy transition policy co‐design experiment in Ida‐Virumaa, a region in Estonia historically dominated by the oil shale industry and with scarce experience of cross‐sector collaboration to date. The experiment had a twofold purpose: (1) to establish a network of people interested in renewable energy and energy efficiency in the region, (2) to develop and validate proposals for policies that could accelerate the energy transition. We found that expectation alignment, social learning, resource mobilization and developmental evaluation can be used to create synergy among participants and can lead to innovative policy proposals. However, collaboration increases the time needed for policy development, the existence of alternative venues can undermine the collaborative process, fluid roles can create confusion around implementation and there might not be many resources to build on in old industrial regions. We conclude that it is still relatively easy to co‐design energy policy or a strategic energy plan even in a setting that does not enjoy a well‐developed collaborative culture but it is much more challenging to co‐create a strong network of committed actors with clear roles in the implementation of policies and plans.
