Authors: Hermundsdottir Fanny , Bjørgum Øyvind , Eide Ann Elida 
Published: May 2024

AbstractThe increasing awareness of the role of fossil fuels in global warming, fluctuating oil and gas prices, and governments' commitments to phase out fossil fuels are driving the Norwegian oil and gas industry to increasingly aim for a transition to more sustainable renewable energy. There are few studies investigating how highly emission‐intensive oil and gas firms can transition into greener industries. In this multiple‐case study, we investigate how these firms can develop green innovations and enter renewable industries by developing dynamic capabilities. We find several microfoundations of dynamic capabilities that are important for green innovation development. Expanding the search window and proactive behavior are key for identifying new opportunities, while developing market insight, cross‐sector collaboration, and structural ambidexterity are crucial to seize and reconfigure opportunities. The findings also illuminate how firm strategy in the sensing stage impacts what opportunities firms seize. The study is one of few studies that explore the microfoundations of dynamic capabilities necessary for entering new and unfamiliar markets, and it contributes to the understanding of the dynamics of the underlying microfoundations and the impact of green innovation type on these dynamics.

Key Clinical MessageMost Japanese patients naturally infected with COVID‐19 were infected after mRNA vaccination, and many maintained high antibody titers due to hybrid immunity. The significance of additional vaccination in hybrid‐immunized cases is highly questionable.AbstractSpontaneous infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) after mRNA vaccination causes a marked increase in antibody titer because of the combined effect of vaccine and infection (“hybrid immunity”). In this study, we discuss the significance of the mRNA vaccine booster inoculation that has been repeatedly performed in Japan. We describe the temporal trends of antibody titers in cases in which antibody titers were markedly increased by hybrid immunization. The antibody titer increased with hybrid immunization and tended to decrease with time. However, several cases maintained high antibody titers for approximately 1 year after coronavirus disease 2019 (COVID‐19) diagnosis, even without booster vaccination. Most Japanese patients naturally infected with COVID‐19 were infected after mRNA vaccination, and many maintained high antibody titers due to hybrid immunity. The significance of additional vaccination in hybrid‐immunized cases is highly questionable regarding cost‐effectiveness and risk–benefit.
Proton‐conducting hydrogel electrolytes with tight contact to binder‐free MXene electrodes for high‐performance thermally chargeable supercapacitor
Authors: Du Zhijian , Li La , Shen Guozhen 
Published: May 2024

AbstractThermally chargeable supercapacitors (TCSCs) have offered exceptional energy‐converting efficiency for absorbing human epidermal heat and generating and storing electrical energy, which then realize continuous power supply to electronic devices, such as sensors and wearable electronic products, in a wide range of practical significance. Here, we proposed a flexible TCSC by attaching binder‐free Ti3C2Tx MXene@PPy electrodes on both ends of the H3PO4@P(AM‐co‐AA‐co‐AYP K+) hydrogel electrolyte, which exhibits a large thermal power of 35.2 mV K−1 at 50% relative humidity and maximum figure of merit of 2.1. The high performances of the fabricated devices can be attributed to the tunable electrical, thermodynamic, thermoelectric, and mechanical properties of the hydrogel electrolyte by adjusting the acid content and the proportion of zwitterionic compound AYP K+ in the hydrogel, and the high photothermal conversion efficiency and electrochemical performance of the electrodes. Moreover, the stable and outstanding thermofvoltage output (∼200 mV) under different time scenarios of the TCSC makes it possible to drive a strain sensor, accomplishing the objectives of a human activity monitor.

Published: May 2024

AbstractMannosylerythritol lipids (MELs) are a class of amphipathic molecules bearing a hydrophilic 4‐O‐β‐D‐mannopyranosyl‐D‐erythritol skeleton. Here, we designed and synthesized four kinds of MEL analogues R‐MEL−A ([2R,3S]‐erythritol type), S‐mannosylthreitol lipid (MTL)‐A ([2S,3S]‐threitol type), R‐MTL−A ([2R,3R]‐threitol type), and α‐S‐MEL−A ([2S,3R]‐erythritol type) using our previously reported boron‐mediated aglycon delivery (BMAD) method and a neighboring group assisted glycosylation method. The selective cytotoxicity of the target compounds against cancer cells was evaluated, with R‐MTL−A showing the highest selective cytotoxicity against human skin squamous carcinoma HSC‐5 cells. Our findings suggest that R‐MTL−A induces necrosis‐like cell death against HSC‐5 cells by decreasing cell membrane fluidity. R‐MTL−A also exhibits an efficient recovery effect on damaged skin cells, indicating that R‐MTL−A has potential as a lead compound for new cosmeceuticals with both cancer cell‐selective toxicity and recovery effects on damaged skin cells.

Published: May 2024

AbstractExcited‐state intramolecular proton transfer (ESIPT) molecules, which feature large Stokes shifts to avoid self‐absorption, play an essential role in photoluminescent bioimaging probes. Herein, we report the development of an ESIPT molecule 3‐(3‐hydroxypyridin‐2‐yl)isoquinolin‐4‐ol (PiQ). PiQ not only undergoes a distinct ESIPT process unlike the symmetrical 2,2′‐bipyridyl‐3,3′‐diol but also exhibits aggregation‐induced emission (AIE) characteristics. PiQ self‐assembles into aggregates with an average size of 241.0±51.9 nm in aqueous solutions, leading to significantly enhanced photoluminescence. On the basis of the ESIPT and AIE characteristics of PiQ, the latter is functionalized with a hydrogen peroxide‐responsive 4‐pinacoratoborylbenzyl group (B) and a carboxylesterase‐responsive acetyl group (A) to produce a photoluminescent probe B−PiQ−A. The potential of PiQ for applications in bioimaging and chemical sensing is underscored by its efficient detection of both endogenous and exogenous hydrogen peroxide in living cells.

Published: May 2024

AbstractUsing carbon disulfide (CS2) and carbonyl sulfide (COS) as sulfur‐containing and one‐carbon feedstocks to make value‐added products is paramount for both pure and applied chemistry and environmental science. One of the practical strategies is to copolymerize these bulk chemicals with epoxides to produce sulfur‐containing polymers. This approach contributes to improving the sustainability of polymer manufacturing, provides highly desired functional polymer materials, and has attracted much attention. However, these copolymerizations invariably exhibit the intensely complicated chemistry of O/S exchange reaction, leading to sulfur‐containing polymers with diverse architectures. As the understanding of O/S exchange continues to deepen, recent efforts have guided significant advances in the synthesis of CS2‐ and COS‐based polymers. This review examines the O/S exchange chemistry and summarizes the recent progress in this field to promote the further advance of synthesizing sulfur‐containing polymers from CS2 and COS.

AbstractConductive polyoxovanadate inorganic‐organic hybrid crystals comprising alkaline earth metal (divalent) cations were successfully obtained with the use of an ionic‐liquid cation having imidazolium and methacryloyl moieties (denoted as MAImC1). Two types of crystals containing decavanadate ([V10O28]6−, V10) anion were obtained as [MAImC1]2Ca2[V10O28] ⋅ 16H2O ⋅ 2 C2H5OH (MAImC1−Ca−V10) and [MAImC1]2Mg2[V10O28] ⋅ 18H2O ⋅ 2 C2H5OH (MAImC1−Mg−V10). Connection modes of the divalent cations were different: Ca2+ cations were connected to V10 to form a {[Ca(H2O)5]2V10O28]}2− anion in MAImC1−Ca−V10, while a discrete [V10O28]6− and hydrated [Mg(H2O)6]2+ were present in MAImC1−Mg−V10. Conductivities under a fully humidified condition at 353 K (80 °C) were high values of 3.0×10−4 S cm−1 for MAImC1−Ca−V10 and 3.3×10−3 S cm−1 for MAImC1−Mg−V10, respectively. The higher conductivity under hydrated conditions suggests proton as a conductive carrier. The better conductivity of MAImC1−Mg−V10 is plausibly derived from the more effective hydrogen‐bonded network in the crystal lattice.

Published: May 2024

AbstractUltrafast spectroscopy can be used to study dynamic processes on femtosecond to nanosecond timescales, but is typically used for photoinduced processes. Several materials can induce ultrafast temperature rises upon absorption of femtosecond laser pulses, in principle allowing to study thermally activated processes, such as (catalytic) reactions, phase transitions, and conformational changes. Gold–silica core–shell nanoparticles are particularly interesting for this, as they can be used in a wide range of media and are chemically inert. Here we computationally model the temporal and spatial temperature profiles of gold nanoparticles with and without silica shell in liquid and gas media. Fast rises in temperature within tens of picoseconds are always observed. This is fast enough to study many of the aforementioned processes. We also validate our results experimentally using a poly(urethane‐urea) exhibiting a temperature‐dependent hydrogen bonding network, which shows local temperatures above 90 °C are reached on this timescale. Moreover, this experiment shows the hydrogen bond breaking in such polymers occurs within tens of picoseconds.

Published: May 2024

AbstractThe potential of acetylene is extremely high both in chemical industry and synthetic applications due to unsaturated nature and the smallest active C≡C unit. The production of many essential necessities is originated from acetylene; however, the formation of acetylene molecule requires a lot of energy. Currently, the access to acetylene is based on coal processing, methane reforming and calcium carbide hydrolysis. Recently, extensive research has been done to decrease the cost of acetylene. In this review, the routes to acetylene were highlighted, considering the energy consumption in kW ⋅ h/t of the product to evaluate the best approach. Since energy prices depend on various regions, the cost of the product is complicated. The manufacturing of acetylene is usually accompanied by formation of by‐products, which may be valuable or not. The review should help to identify current status and not overlook promising approaches.
Forest harvest causes rapid changes of maternal investment strategies in ground beetles
Authors: Egli Lauren , Work Timothy T. 
Published: May 2024

AbstractSpecies recovery following anthropogenic disturbances will depend on adaptations in survivorship and fecundity. Life‐history theory predicts increased environmental stress will result in (1) shifts in resource allocation from fecundity to body growth/maintenance and (2) increased provisioning among offspring at the cost of reproductive output. For remnant populations that persist after forest harvesting, selection mediated through anthropogenic disturbances may affect resilience to additional stressors such as climate change. We tested how rapid changes in environmental conditions affected maternal investment strategies in two ground beetle species, Pterostichus pensylvanicus and Pterostichus coracinus, by comparing fecundity and survivorship in populations from recently clear‐cut and uncut habitats. Using parents drawn from clear‐cut or uncut stands, we reared progeny in both common garden and reciprocal transplant experiments. In P. pensylvanicus, we found that neither lineage nor rearing habitat affected the number of eggs laid per female or survivorship of offspring. However, eggs laid by females from clear‐cuts were more likely to hatch and offspring reached maturity more quickly, suggesting increased provisioning per offspring. In P. coracinus, females from clear‐cuts laid more eggs, and their eggs hatched more rapidly and had greater hatching success, suggesting increased investment in overall reproductive output and increased offspring provisioning. In the reciprocal transplant, we observed significant habitat by lineage interactions on survival in P. coracinus, with survivorship increasing when progeny were reared in novel habitats. In both species, increased maternal investment among offspring was not associated with a reduction in overall reproductive output, as anticipated. However, maternal investment among offspring declined with increasing female size, implying trade‐offs between increased metabolic demand and fecundity. Taken together, our work suggests that females from more stressful, clear‐cut habitats increased investment in fecundity, compared to females from uncut habitats, and may compensate for larval mortality. These changes were driven by smaller individuals, suggesting that increased environmental stress can influence the relationship between female size and maternal investment strategy. Additionally, reciprocal increases in offspring survivorship in habitats other than the parents suggest that adjacent areas between unharvested and clear‐cut habitat may be useful in maintaining biodiversity under future climate stressors.

AbstractAgainst the backdrop of escalating antibiotic pollution, this study presents a novel approach to remediation using a photothermal heterogeneous Fenton‐like catalyst, Bi12CoO20/rGO, which efficiently activates peroxymonosulfate (PMS) under near‐infrared (NIR) light. This catalyst capitalize on the NIR absorption capabilities of Bi12CoO20 and the electron transfer properties of reduced graphene oxide (rGO). The restored sp2 structure of rGO serves as a conduit for electron transfer, crucial for the redox cycle of Co2+/Co3+ that facilitates PMS activation. Moreover, the incorporation of rGO significantly boosts the NIR absorption capacity of Bi12CoO20, thereby enhancing the photothermal conversion efficiency of the composite and further promoting PMS activation. This synergy enables efficient light‐to‐heat conversion and PMS activation, generating reactive oxygen species (ROS) essential for antibiotic degradation. Using levofloxacin (LVX) as a representative pollutant, the developed system achieves an impressive 99 % degradation rate within just 30 min under Bi12CoO20/rGO+PMS+NIR conditions. Moreover, this approach demonstrates robust stability and adaptability across diverse water compositions and pH ranges. Its eco‐friendly nature and renewable characteristics position it as a promising solution for combating antibiotic pollution through photothermal Fenton‐like technology, thereby harnessing solar energy for environmental remediation and fostering sustainable water management practices.

AbstractThe drying procedure is an important consideration for the silicon powder processing. Herein, a comparative investigation of the drying efficiency, drying performance, and energy consumption of silicon powder after separation and purification of monocrystal silicon cutting slurry by using the hot air, far‐infrared and microwave drying treatments. The results show that microwave drying of 30 g silicon powder takes only 12 min, which is much shorter than hot air drying of 200 min and far infrared drying of 40 min. The water evaporation energy consumption of microwave drying reached 73.5 g/kW·h, which was 3.3 times than that of far infrared drying and 16.5 times than that of hot air drying. For 1 kg of silicon powder, the power consumption of microwave drying was 8 kW·h, while the far‐infrared drying was 26.7 kW·h, and the hot air drying was 133.4 kW·h, respectively. Therefore, effects of microwave power, drying temperature and drying time on the dehydration rate of silicon powder were investigated and optimized by response surface method, demonstrating that the microwave drying dehydration rate of 30 g silicon powder could reach 97.65%, and the power consumption could be reduced to 6.7 kW·h/kg under the conditions of microwave power of 1000 W, drying temperature of 89°C and drying time of 12 min. The present study shows that microwave drying of silicon powder is an energy‐saving and efficient process with good industrial application prospects.
First‐principles calculations on LaX3 (X: Sb, Sn) as electrode material for lithium‐ion batteries

Published: May 2024

AbstractUsing first‐principle calculations, we investigate the rare‐earth intermetallic compound LaX3 (X = Sb and Sn) as a cathode material for rechargeable lithium‐ion batteries (LIBs). The calculations have been performed to look into the stability of the structure and the electronic properties of host LaX3 as well as its lithiated phases, LixLa1−xX3 (0 < x ≤ 1). In this study, we have observed a structural phase transformation of these intermetallic compounds from a cubic to a tetragonal structure upon lithiation to host structure. The ground state energy is calculated using the WIEN2k package to determine the structure stability and volume change due to lithium addition, which is further used to calculate the formation energy, open circuit voltage (OCV), and lithium‐ion storage capacity. The equilibrium structural parameters for all the phases are determined by achieving a total energy convergence of 10−4 Ry. The estimated band structure along high‐symmetry lines in the first Brillouin zone and the total as well as partial density of states demonstrate unequivocally that the addition of lithium does not change the metallic nature of these electrode materials. We have also calculated the theoretical lithium‐ion storage capacity and OCV for all the compounds. Despite a higher value for OCV larger than 5 V, many of the investigated materials could not be found suitable from a synthesis point of view due to positive formation energies. The formation energy calculation shows that LaSb3, with a 50% concentration of Li, is the most stable compound out of those investigated here. The calculated OCV for Li0.5La0.5Sb3 is 4.27 V. This is substantially higher than the value obtained up to this point for LIBs, which ranges from 3.20 to 3.65 V/cell. These improved results related to the most stable alloy (Li0.5La0.5Sb3) investigated in this work indicate that it is necessary to check the experimental feasibility of its synthesis and actual device performance.
Modeling Full Life-Cycle Effects of Copper on Brook Trout (Salvelinus fontinalis) Populations

Published: May 2024

Abstract
Population models are increasingly used to predict population-level effects of chemicals. For trout, most toxicity data are available on early-life stages, but this may cause population models to miss true population-level effects. We predicted population-level effects of copper (Cu) on a brook trout (Salvelinus fontinalis) population based on individual-level effects observed in either a life-cycle study or an early-life stage study. We assessed the effect of Cu on predicted trout densities (both total and different age classes) and the importance of accounting for effects on the full life cycle compared with only early-life stage effects. Additionally, uncertainty about the death mechanism and growth effects was evaluated by comparing the effect of different implementation methods: individual tolerance (IT) versus stochastic death (SD) and continuous versus temporary growth effects. For the life-cycle study, the same population-level no-observed-effect concentration (NOECpop) was predicted as the lowest reported individual-level NOEC (NOECind; 9.5 µg/L) using IT. For SD, the NOECpop was predicted to be lower than the NOECind for young-of-the-year and 1-year-old trout (3.4 µg/L), but similar for older trout (9.5 µg/L). The implementation method for growth effects did not affect the NOECpop of the life-cycle study. Simulations based solely on the early-life stage effects within the life-cycle study predicted unbounded NOECpop values (≥32.5 µg/L), that is, &gt;3.4 times higher than the NOECpop based on all life-cycle effects. For the early-life stage study, the NOECpop for both IT and SD were predicted to be &gt;2.6 times higher than the lowest reported NOECind. Overall, we demonstrate that effects on trout populations can be underestimated if predictions are solely based on toxicity data with early-life stages.

A general computational framework for Lagrangian hydrodynamic scheme. I: Unification of staggered‐grid and cell‐centered methods
Authors: Xu Xihua 
Published: May 2024

AbstractThis paper focuses on a general computational framework to unify both Lagrangian staggered‐grid hydrodynamic (SGH) and cell‐centered hydrodynamic (CCH) methods. One challenge is that artificial viscosity has contained empirical parameters in the SGH method for seven decades. To address this challenge, a new relationship between pressure and velocity is constructed using specific volume as a medium. Another challenge is that entropy is increasing in isentropic flows for the CCH method. To overcome this second challenge, the forces acting on a target cell are split into linear and quadratic terms in the CCH method. The numerical results of the two methods are almost identical. The scheme is more general than both existing SGH and CCH methods.
