Excitation of Chiral Cavity Plasmon Resonances in Film‐Coupled Chiral Au Nanoparticles
Authors: Wang Jing , Zheng Jiapeng , Li Kwai Hei , Wang Jianfang , Lin Hai‐Qing , Shao Lei 
Published: February 2023

AbstractChiral plasmonic nanostructures have attracted increasing attention because of their superchiral near‐fields as well as strong far‐field chiral optical response. Recently, the development of chemical synthesis methods enabled the large‐scale manufacturing of three‐dimensional colloidal chiral plasmonic nanocrystals. Further improving the chiral optical response of such nanostructures will greatly facilitate their practical applications. In this work, it is found both in calculations and experiments that chiral cavity plasmon resonances can be excited in film‐coupled chiral Au helicoid nanoparticles, enabling the significant enhancement of the nanostructure chiral optical response. In addition, it is demonstrated from simulation that the chiral cavity mode can modulate the emission polarization of a point electric dipole placed in the nanocavity formed by the nanoparticle and the Au film, allowing the emission of almost circularly polarized photons by the linear dipole with the emission circular polarization anisotropy factor reaching as high as 93%. The film‐coupled chiral plasmonic nanoparticles therefore provide a promising platform for the construction of advanced chiral optical devices such as on‐chip nonreciprocal nanoscale light sources, chiral plasmonic sensors, chiral metamaterials, plasmonically enabled valleytronic devices, and nanophotonic circuits for future on‐chip communication applications.

AbstractOffering high specificity and selectivity, molecularly imprinted polymers (MIPs) are synthetic polymeric affinity reagents that have become increasingly popular over the last couple of decades. Due to their long‐term chemical and physical stability and low production cost, they have become an increasingly popular choice of receptor in the realm of sense. MIPs have therefore been associated with the detection of small molecules, proteins, cells, and pathogens, proving a highly robust and useful tool in the production of next‐gen sensing platforms. This said, the development of these sensors pivots on one simple fact; these receptors have to be deposited onto a substrate for their desired application. The deposition of MIPs during sensor fabrication is therefore of great importance, with the field utilizing an array of mechanical and chemical deposition methods to achieve this. To this end, this review, therefore, sets aim at coalescing these different deposition approaches, classifying them, and outlining their utility when it comes to receptor design and integration. Thus, offering a knowledge base on current deposition methods, potential future approaches and analyzing where the MIP deposition field is tending toward.

Abstract

Coral reef fish assemblages are threatened globally, underscoring the need for data‐driven management to reduce threats and restore populations. Comparing fishery management approaches is aided by a detailed understanding of the key factors controlling species’ abundances.
The aims of this study were to assess the importance of biophysical factors compared with fishing impacts on the biomass of reef fishes on Florida’s Coral Reef and to evaluate the potential effects of common management interventions on fish biomass.
Fishing impact was estimated using a fishery‐independent modelling approach and the biomass of the snapper–grouper complex as a proxy for the effects of fishing. Using a separate subset of data from underwater fish surveys, estimated fishing impact was then combined with 18 biophysical variables to model the current biomass of all reef fish species, the snapper–grouper complex, grazing species and species collected for aquaria.
Models explained between 51 and 64% of the variance in fish biomass for the fish groups. The strongest predictor of biomass in the snapper–grouper complex was fishing impact (accounting for 25.2% of the explained variance), whereas reef complexity was the strongest predictor for all other groups.
High‐resolution maps were produced from the statistical models, including maps of current fish biomass and maps of potential biomass under several management scenarios: a no‐take marine reserve, moderate and extensive coral restoration and the addition of artificial benthic structure. Adding structure had the largest single impact on predicted fish biomass (23–72% increase from current estimated levels). However, beneficial synergies emerged when combining habitat‐based management and fishing closures, with some combinations resulting in a reef‐wide averaged 89% increase in biomass relative to current estimated levels.
The results suggest that conservation strategies aimed at protecting and increasing structural reef complexity should be an important part of fishery management discussions.

AbstractBumphead parrotfish (Bolbometopon muricatum) and Napoleon wrasse (Cheilinus undulatus) are large, charismatic species with high economic and cultural value in Palau and are important for ecosystem function.As a result of intense fishing pressure, landings in Palau for both species declined dramatically in the 1990s and, in response, national legislation was enacted in 2006 that imposed a total ban on the extraction, possession, and sale of both species.In 2013 and 2021, fisheries‐independent stock assessments were conducted and found that the spawning potential ratios (SPRs) for bumphead parrotfish increased slightly from 30% to 34%. Conversely, the SPRs for Napoleon wrasse declined from 12% in 2013 to 4% in 2021. Despite the fishery being closed since 2006, these data suggest the likelihood of significant poaching, resulting in low SPR values, particularly for Napoleon wrasse.Prior to the COVID‐19 pandemic, marine tourism played a central role in the economic and social life of Palau. A willingness‐to‐pay survey found that divers would pay $1.27 million (2020 USD) more for strictly managed catches of both species, and nearly $3.00 million more if the fishery remained closed.The total market value for bumphead parrotfish peaked in 1995 at $112,190. The peak total market value for Napoleon wrasse was $66,434 in 2002. The welfare gain/loss for diver tourism is an order of magnitude greater than the fishery market gain/loss, and healthy marine ecosystems are essential for the post‐COVID‐19 economic recovery of Palau. However, because of the cultural importance of these species, there is a desire to manage this fishery for customary use.Opening a general subsistence harvest season is not recommended ecologically; however, the results suggest that if the SPR of bumphead parrotfish can recover to 40%, a limited quota of individuals with a total length of >95 cm could be sustained, which could be allocated via lottery. However, the fishery for Napoleon wrasse should remain closed given the extremely low SPR values and limited number of large adults in the population.

AbstractObjectiveDepression in mothers impacts children negatively. Understanding the antecedents and the underlying mechanisms of depression is essential in helping clinicians target depressive symptoms effectively. This study investigated the relationship between parental burnout and depression in mothers and examined the mediation role of Maladaptive Coping modes.MethodA total of 224 mothers participated in this study and completed the Parental Burnout Assessment scale, Patient Health Questionnaire, and items related to coping modes in Schema Mode Inventory.ResultsData analysis with structural equation modeling revealed that depression and parental burnout were positively and significantly related. Bootstrap analysis showed that all coping modes except the Self‐Aggrandizer mode act as mediators between parental burnout and depression in mothers. Detached Protector mode had the strongest indirect effect on depression.ConclusionThe results suggest Maladaptive Coping modes mediate the association between parental burnout and depression. The present finding provides evidence that Maladaptive Coping modes can be considered probable mediational mechanisms that relate depression to parental burnout in mothers and may serve as potential interventional targets.

AbstractPurposeMetastasis is the end stage of renal cell carcinoma (RCC), and clear cell renal cell carcinoma (ccRCC) is the most common malignant subtype. The hypoxic microenvironment is a common feature in ccRCC and plays an essential role in the regulation of epithelial–mesenchymal transition (EMT). Accumulating evidence manifests that long non‐coding RNAs (lncRNAs) participate in RCC tumorigenesis and regulate hypoxia‐induced EMT. Here, we identified a lncRNA RP11‐367G18.1 induced by hypoxia, that was overexpressed in ccRCC tissues.MethodsA total of 216 specimens, including 149 ccRCC tumor samples and 67 related normal kidney parenchyma tissue samples, were collected. To investigate the biological fucntions of RP11.367G18.1 in ccRCC, migration, invasion, soft agar colony formation, xenograft tumorigenicity assays, and tail vein and orthotopic metastatic mouse models were performed. The relationship between RP11‐367G18.1 and downstream signaling was analyzed utilizing reporter assay, RNA pull‐down, chromatin immunopreciptation, and chromatin isolation by RNA purification assays.ResultsHypoxic conditions and overexpression of HIF‐1α increased the level of RP11‐367G18.1. RP11‐367G18.1 induced EMT and enhanced cell migration and invasion through variant 2. Inhibition of RP11‐367G18.1 variant 2 reversed hypoxia‐induced EMT phenotypes. An in vivo study revealed that RP11‐367G18.1 variant 2 was required for hypoxia‐induced tumor growth and metastasis in ccRCC. Mechanistically, RP11‐367G18.1 variant 2 interacted with p300 histone acetyltransferase to regulate lysine 16 acetylation on histone 4 (H4K16Ac), thus contributing to hypoxia‐regulated gene expression. Clinically, RP11‐367G18.1 variant 2 was upregulated in ccRCC tissues, particularly metastatic ccRCC tissues, and it is linked to poor overall survival.ConclusionThese findings demonstrate the prognostic value and EMT‐promoting role of RP11‐367G18.1 and indicate that this lncRNA may provide a therapeutic target for ccRCC.

AbstractBackgroundIn high‐income countries, hope facilitates parental coping and builds the clinical relationship between families of children with cancer and their clinicians. However, the manifestation of hope in low‐ and middle‐income countries (LMICs) remains poorly understood. Our study explores Guatemalan parents' experiences with hope during the pediatric oncology diagnostic process and aims to identify discrete actions clinicians take to support hope.MethodsThis qualitative study utilized audio‐recordings of the diagnostic process and an additional semi‐structured interview for 20 families of children with cancer at Unidad Nacional de Oncología Pediátrica in Guatemala. Spanish audio‐recordings were translated into English, transcribed, and coded using a priori and novel codes. Thematic content analysis using constant comparative methods explored parents' hopes and concerns.ResultsAt diagnosis, Guatemalan parents expressed both hopes and concerns related to the entire cancer continuum. Throughout the diagnostic process, hope grew as concerns were alleviated. Clinicians supported hope by creating a supportive environment, providing information, affirming religious beliefs, and empowering parents. These strategies helped parents shift their focus from fear and uncertainty toward hope for their child's future. Parents expressed that establishing hope improved mood, promoted acceptance, and enabled them to care for themselves and their children.ConclusionThese results confirm the relevance of supporting hope in pediatric oncology settings in LMICs and suggest that culture informs hope‐related needs. Supporting hope is critical across cultures and can be integrated into clinical conversation using the four processes identified by our results.

AbstractThe rational synergy of chemical composition and spatial nanostructures of electrode materials play important roles in high‐performance energy storage devices. Here, we designed pea‐like MoS2@NiS1.03–carbon hollow nanofibers using a simple electrospinning and thermal treatment method. The hierarchical hollow nanofiber is composed of a nitrogen‐doped carbon‐coated NiS1.03 tube wall, in which pea‐like uniformly discrete MoS2 nanoparticles are enclosed. As a sodium‐ion battery electrode material, the MoS2@NiS1.03–carbon hollow nanofibers have abundant diphasic heterointerfaces, a conductive network, and appropriate volume variation‐buffering spaces, which can facilitate ion diffusion kinetics, shorten the diffusion path of electrons/ion, and buffer volume expansion during Na+ insertion/extraction. It shows outstanding rate capacity and long‐cycle performance in a sodium‐ion battery. This heterogeneous hollow nanoarchitectures designing enlightens an efficacious strategy to boost the capacity and long‐life stability of sodium storage performance of electrode materials.

AbstractIons appear as active components in diverse materials. Here, the bonding energy between mechanically interlocked molecules (MIMs) or their acyclic/cyclic molecular derivatives and i) Cl− and Br− ions and/or ii) Na+ and K+ ions, have been investigated. The chemical environment provided by MIMs is less preferably to recognize ionic species compared to unconstrained interactions that are furnished by acyclic molecules. However, MIMs can be more adequate structures for ionic recognition than cyclic compounds if a chemical arrangement of the bond sites that relevantly support more favorable interactions with ions compared to Pauli repulsive ambient is provided. The hydrogen replacement by electron donor (−NH2) or acceptor (−NO2) groups in MIMs favors the anion/cation recognition due to decreased Pauli repulsion energy and/or more attractive non‐covalent bonds. This study clarifies the chemical environment provided by MIMs to interact with ions and highlights these molecules as relevant structures to realize ionic sensing.

Published: February 2023

Comprehensive SummaryThe merits of intrinsic electrical conductivity, high specific surface area, tunable chemical composition and tailor‐made properties enable two‐dimensional conductive metal‐organic frameworks (2D c‐MOFs) as promising next‐generation electrode materials in the field of energy storage and conversion. Herein, we have designed and synthesized a novel pyrazine‐based 2D c‐MOF (TPQG‐Cu‐MOF) bearing extended π‐conjugated structure and abundant redox active sites. Thanks to the excellent redox reversibility of pyrazine units and CuO2 units, as well as the insolubility of the rigid framework skeleton, TPQG‐Cu‐MOF as the cathode material of lithium‐ion battery exhibits a reversible specific capacity (150.2 mAh·g–1 at 20 mAh·g–1), good cycling stability (capacity retention of 82.6% after 500 cycles at 1 A·g–1) and excellent rate performance. Comprehensive ex‐situ spectroscopic studies revealed the reversible redox activity of pyrazine units and CuO2 units of TPQG‐Cu‐MOF during the Li+ insertion/extraction process. The deepening fundamental understanding of the structure‐property relationship was proposed, which might pave the way for further development of efficient MOF‐based energy storage devices.

Published: February 2023

AbstractWe disclose herein our detailed investigation into the Barton copper‐promoted C3‐arylation of indoles using triarylbismuth bis(trifluoroacetates). The arylation of unsubstituted 1H‐indole using Barton's conditions gave a low yield of the C3‐arylated indole, along with small amounts of the product of double C2/C3‐arylation and traces of the product of C2 arylation. On the contrary, the arylation of indoles blocked at the C2 position is highly efficient, affording the desired products of C3‐arylation in good to excellent yields. The reaction operates under simple conditions, shows good substrate scope, excellent functional group compatibility, and allows the transfer of electron‐neutral or deficient aryl groups. Computational studies propose a mechanism involving a trifluoroacetate‐assisted C−H activation step.

AbstractOrganic photoredox catalysis is a versatile tool for accessing a wide range of synthetic transformations. Towards the development of a new class of organophotoredox catalysts, we have employed phenalenyl, an odd alternant hydrocarbon (OAH), for reductive C−C coupling reactions. Phenalenyl can adopt a stable open‐shell state (radical), using its non‐bonding molecular orbital. To date, chemically induced phenalenyl‐based radicals have been extensively explored in designing various intriguing organic materials and recently towards electron transfer catalysis. However, the photochemical generation of phenalenyl‐based radicals is rare. In this work, we report the photoinduced generation of phenalenyl‐based radicals with detailed mechanistic studies such as steady‐state absorption, time‐resolved transient absorption spectroscopy, and in‐situ absorption kinetic experiments to authenticate the generation of photo‐induced phenalenyl radicals. In addition, we present results demonstrating that this novel catalytic species can be applied to reductive pinacol coupling catalysis and reductive alkylation of terminal alkynes.

AbstractInfectious diseases pose a significant threat to global health and biodiversity. Yet, predicting the spatiotemporal dynamics of wildlife epizootics remains challenging. Disease outbreaks result from complex nonlinear interactions among a large collection of variables that rarely adhere to the assumptions of parametric regression modeling. We adopted a nonparametric machine learning approach to model wildlife epizootics and population recovery, using the disease system of colonial black‐tailed prairie dogs (BTPD, Cynomys ludovicianus) and sylvatic plague as an example. We synthesized colony data between 2001 and 2020 from eight USDA Forest Service National Grasslands across the range of BTPDs in central North America. We then modeled extinctions due to plague and colony recovery of BTPDs in relation to complex interactions among climate, topoedaphic variables, colony characteristics, and disease history. Extinctions due to plague occurred more frequently when BTPD colonies were spatially clustered, in closer proximity to colonies decimated by plague during the previous year, following cooler than average temperatures the previous summer, and when wetter winter/springs were preceded by drier summers/falls. Rigorous cross‐validations and spatial predictions indicated that our final models predicted plague outbreaks and colony recovery in BTPD with high accuracy (e.g., AUC generally >0.80). Thus, these spatially explicit models can reliably predict the spatial and temporal dynamics of wildlife epizootics and subsequent population recovery in a highly complex host–pathogen system. Our models can be used to support strategic management planning (e.g., plague mitigation) to optimize benefits of this keystone species to associated wildlife communities and ecosystem functioning. This optimization can reduce conflicts among different landowners and resource managers, as well as economic losses to the ranching industry. More broadly, our big data–model integration approach provides a general framework for spatially explicit forecasting of disease‐induced population fluctuations for use in natural resource management decision‐making.

AbstractIn recent years, the development of light‐mediated methods for synthetic applications has attracted high interest, because such methods constitute alternative approaches for the production of valuable chemical products. We study herein a photochemical protocol for the synthesis of Weinreb amides and morpholine amides from carboxylic acids. Various carboxylic acids were directly coupled to N,O‐dimethylhydroxylamine, upon irradiation with either LED 370 nm or sunlight in the presence of 4‐dimethylaminopyridine and bromotrichloromethane, providing Weinreb amides in moderate to high yields. Similarly, morpholine amides were obtained in satisfactory to high yields under sunlight or LED 370 nm irradiation. Thus, the versatile building blocks Weinreb amides and morpholine amides may be efficiently synthesized directly from carboxylic acids by light‐mediated approaches, without the need of coupling reagents or pre‐activation of carboxylic acids.
