AbstractColloidal quantum wells (CQWs) are excellent candidates for lighting and display applications owing to their narrow emission linewidths (<30 nm). However, realizing their efficient and stable light‐emitting solids remains a challenge. To address this problem, stable, efficient solids of CQWs incorporated into crystal matrices are shown. Green‐emitting CdSe/CdS core/crown and red‐emitting CdSe/CdS core/shell CQWs wrapped into these crystal solids are employed as proof‐of‐concept demonstrations of light‐emitting diode (LED) integration targeting a wide color span in display backlighting. The quantum yield of the green‐ and red‐emitting CQW‐containing solids of sucrose reach ≈20% and ≈55%, respectively, while emission linewidths and peak wavelengths remain almost unaltered. Furthermore, sucrose matrix preserves ≈70% and ≈45% of the initial emission intensity of the green‐ and red‐emitting CQWs after >60 h, respectively, which is ≈4× and ≈2× better than the drop‐casted CQW films and reference (KCl) host. Color‐converting LEDs of these green‐ and red‐emitting CQWs in sucrose possess luminous efficiencies 122 and 189 lm W−1elect, respectively. With the liquid crystal display filters, this becomes 39 and 86 lm W−1elect, respectively, providing with a color gamut 25% broader than the National Television Standards Committee standard. These results prove that CQW solids enable efficient and stable color converters for display and lighting applications.
Optical Magnetism‐Induced Dual Anisotropy in Dielectric Nanoantennas

Published: June 2022

AbstractDirectional polarization of atoms in crystalline dielectrics leads to anisotropic permittivities that usually enable phase delay between two orthogonal components of light in waveplates. However, amplitude‐type anisotropy is seldom observed in natural dielectrics because optical absorption of transparent materials is mainly dominated by polarization‐insensitive bandgap. This work introduces the co‐existence of both amplitude‐ and phase‐type anisotropies in artificial dielectric rectangle nanoantennas by using a united approach of directionally excited magnetic resonances. When anti‐parallel magnetic dipolar modes (AMDMs) are induced horizontally, the resulting electric fields at the antenna−substrate interface behave, surprisingly, like those of surface plasmonic polaritons (SPPs), leading to nearly full reflectance of light. But, for the incidence of the other polarization, only vertically located AMDMs arise with high transmission, thus yielding amplitude‐type anisotropy. For phase‐type anisotropy, both orthogonal polarizations of light excite vertical AMDMs with high transmission and an additional polarization‐dependent phase. Both anisotropies are multiplexed into a polarization‐dependent color‐printed hologram for optical anticounterfeiting.

AbstractDespite remarkable luminescent performance of 0D lead halide perovskites, achieving highly efficient blue light emission is extremely challenging and crucial for this domain. Considering the high toxicity of Pb2+ ion, it is significant to explore water‐stable lead‐free 0D halides as highly efficient and stable blue emitting materials. To address these issues, a family of 0D hybrid zinc halides of AZnBr4 (A = EP, BP, and TMPDA) based on discrete [ZnBr4]2− tetrahedrons is herein reported as desirable blue light emitters. The wide band gaps enable these 0D halides to display highly efficient blue light emissions (452–485 nm) with highest photoluminescence quantum yield (PLQY) of 35.47%. More importantly, all these 0D halides present extraordinary chemical stabilities in humid air and water for one month, and are also capable of withstanding extreme pH conditions in the range of 0–14, likely the widest observed pH range for perovskites. Notably, the ultrahigh chemical stabilities of 0D zinc halides are nearly unmatchable among all known literature perovskite materials to the best of the authors’ knowledge. Combined superiorities of unusual blue light emission, promising PLQY, ultrahigh stability, and non‐toxicity highlight the potential optoelectronic applications in wide chemical environments for these 0D zinc halides.

AbstractThe overall effectiveness of nonlinear optical processes along extended nonlinear media highly depends on the fulfillment of the phase‐matching condition for pump and generated fields. This is traditionally accomplished by exploiting the birefringence of nonlinear crystals requiring long interaction lengths (cm‐scale). For nonbirefringent media and integrated photonic devices, modal phase matching can compensate the index mismatch. Here, the various interacting waves propagate in transverse modes with appropriate phase velocities, but they suffer from a low refractive index contrast and cm‐scale interaction lengths. This work harnesses modal phase matching for third‐harmonic generation (THG) in plasmonic waveguides using an organic polymer (poly[3‐hexylthiophene‐2,5‐diyl]) as the nonlinear medium. One demonstrates experimentally an effective interaction area as small as ≈ 0.11 µm2 and the phase‐matched modal dispersion results in THG efficiency as high as ≈ 10–3 W‐2 within an effective length scale of ≈ 4.3 µm. THG also shows a strong correlation with the polarization of the incident laser beam, corresponding to the excitation of the antisymmetric plasmonic modes, corroborating that plasmonic modal phase matching is achieved. This large reduction in device area of orders of magnitude is interesting for various applications where space is critical (e.g., device integration or on‐chip applications).

Published: June 2022

AbstractMoS2/C composites constructed with van der Waals forces have been extensively applied in lithium–sulfur (Li–S) batteries. However, the catalytic conversion effect on polysulfides is limited because the weak electronic interactions between the composite interfaces cannot fundamentally improve the intrinsic electronic conductivity of MoS2. Herein, density functional theory calculations reveal that the MoS2 and nitrogen‐doped carbon composite with an Mo–O–C bond can promote the catalytic conversion of polysulfides with a Gibbs free energy of only 0.19 eV and a low dissociation energy barrier of 0.48 eV, owing to the strong covalent coupling effect on the heterogeneous interface. Guided by theoretical calculations, a robust MoS2 strongly coupled with a 3D carbon matrix composed of nitrogen‐doped reduced graphene oxide and carbonized melamine foam is designed and constructed as a multifunctional coating layer for lithium–sulfur batteries. As a result, excellent electrochemical performance is achieved for Li–S batteries, with a capacity of 615 mAh g–1 at 5 C, an areal capacity of 6.11 mAh cm–2, and a low self‐discharge of only 8.6% by resting for five days at 0.5 C. This study opens a new avenue for designing 2D material composites toward promoted catalytic conversion of polysulfides.

Published: June 2022

AbstractSmart windows can selectively regulate excess solar radiation to reduce heating and cooling energy consumption in the built environment. However, the inevitable dissipation of ultraviolet and near‐infrared into waste heat results in inefficient solar utilization. Herein, a dual‐band selective solar harvesting (SSH) window is developed to realize full‐spectrum utilization. A transparent photovoltaic, converting ultraviolet into electricity, and a transparent solar absorber, converting near‐infrared into thermal energy, are integrated and coupled with a ventilation system to extract heat for indoor use. Compared with common transparent photovoltaics, the SSH window increases solar harvesting efficiency up to threefold while maintaining a considerable visible transmittance. Simulations suggest that the SSH window, besides generating electricity, delivers energy savings by over 30% higher than common smart windows. This is the first integration of transparent photovoltaic and transparent solar absorber into a window, which may open up a new avenue for the development of energy‐efficient buildings.

AbstractTwo‐dimensional (2D) magnetic semiconductors are considered to have great application prospects in spintronic logic devices, memory devices, and photodetectors, due to their unique structures and outstanding physical properties in 2D confinement. Understanding the influence of magnetism on optical/optoelectronic properties of 2D magnetic semiconductors is a significant issue for constructing multifunctional electronic devices and implementing sophisticated functions. Herein, the influence of spin ordering and magnons on the optical/optoelectronic properties of 2D magnetic semiconductor α‐MnSe synthesized by space‐confined chemical vapor deposition (CVD) is explored systematically. The spin‐ordering‐induced magnetic phase transition triggers temperature‐dependent photoluminescence spectra to produce a huge transition at Néel temperature (TN ≈ 160 K). The magnons‐ and defects‐induced emissions are the primary luminescence path below TN and direct internal 4aT1g→6A1g transition‐induced emissions are the main luminescence path above TN. Additionally, the magnons and defect structures endow 2D α‐MnSe with a broadband luminescence from 550 to 880 nm, and an ultraviolet–near‐infrared photoresponse from 365 to 808 nm. Moreover, the device also demonstrates improved photodetection performance at 80 K, possibly influenced by spin ordering and trap states associated with defects. These above findings indicate that 2D magnetic semiconductor α‐MnSe provides an excellent platform for magneto‐optical and magneto‐optoelectronic research.

AbstractReconfigurability of a device that allows tuning of its shape and stiffness is utilized for personal electronics to provide an optimal mechanical interface for an intended purpose. Recent approaches in developing such transformative electronic systems (TES) involved the use of gallium liquid metal, which can change its liquid–solid phase by temperature to facilitate stiffness control of the device. However, the current design cannot withstand excessive heat during outdoor applications, leading to undesired softening of the device when the rigid mode of operation is favored. Here, a gallium‐based TES integrated with a flexible and stretchable radiative cooler is presented, which offers zero‐power thermal management for reliable rigid mode operation in the hot outdoors. The radiative cooler can both effectively reflect the heat transfer from the sun and emit thermal energy. It, therefore, allows a TES‐in‐the‐air to maintain its temperature below the melting point of gallium (29.8 ℃) under hot weather with strong sun exposure, thus preventing unwanted softening of the device. Comprehensive studies on optical, thermal, and mechanical characteristics of radiative‐cooler‐integrated TES, along with a proof‐of‐concept demonstration in the hot outdoors verify the reliability of this design approach, suggesting the possibility of expanding the use of TES in various environments.
Wastewater‐recycled struvite as a phosphorus source in a wheat–soybean double‐crop production system in eastern Arkansas
Authors: Omidire Niyi S. , Brye Kristofor R. 
Published: June 2022

AbstractFertilizer‐phosphorus (P) sources are mainly derived from rock phosphate (RP), which is a finite, actively mined resource. With growing human populations globally, alternative P sources are vitally important to ensure future food security. Precipitation of the mineral struvite (MgNH4PO4·6H2O) from wastewater could be a potential alternative fertilizer‐P option from crop production. The objective of this study was to evaluate the effects of chemically precipitated struvite (CPST), compared with triple superphosphate (TSP) and an unamended control (UC) treatment, and irrigation (irrigated and non‐irrigated/dryland) on above‐ (dry matter, yield, and tissue‐N, ‐P, and ‐Mg concentrations and uptake) and belowground (root tissue N, P, and Mg concentrations) soybean [Glycine max (L.) Merr.] and wheat (Triticum aestivum L.) response in a wheat–soybean, double‐crop production system on a silt‐loam soil (Aquic Fraglossudalfs) in eastern Arkansas. Soybean aboveground and wheat belowground Mg concentrations were 1.1 and 1.2 times, respectively, greater (p < .05) from CPST than from TSP, while soybean belowground Mg and wheat stem P concentrations were similar between CPST and TSP. Wheat stem Mg and belowground N concentrations were 1.1 times greater (p < .05) from TSP than from CPST. Soybean seed P and Mg concentrations were 1.2 and 1.1 times, respectively, greater (p < .05) under irrigated than under dryland management. Results substantiate the use of CPST as a potential alternative fertilizer‐P and ‐Mg source on a silt‐loam soil for crop production. Using wastewater‐recovered nutrients in a production‐scale setting may offset the need for energy‐intensive commercial fertilizers to supply essential plant nutrients.

Published: June 2022

AbstractIn the United States, the production of many fruits and vegetables (F&Vs) is concentrated in a few key regions of the country, and it may not be possible to maintain or increase output from these areas due to natural resource constraints and climate change. Rather, developing new and more geographically diverse production systems may be necessary to meet food needs and adapt to changing conditions. However, there is currently a limited understanding of the availability and location of suitable land where future production could occur. In this project, we developed geospatial models to identify and quantify land suitable for producing F&V crops across the contiguous United States based on biophysical constraints. Suitability was based on key criteria related to land cover and use, topography, soil properties, and climate. We found tremendous potential to expand F&V production at the national level, identifying 333 million hectares of suitable land, 47% of which is currently used for agriculture. Suitable land to produce most F&Vs exists across the United States, indicating that there is significant potential to geographically diversify production in the future, though tropical and sub‐tropical fruits are restricted to the southern areas of the country. These results provide a starting point for identifying opportunities to expand F&V production, reduce geographic concentration, and establish new supply chains.

Published: June 2022

AbstractThe decline of Drosophila climbing behavior is one of the common phenomena of Drosophila aging. The so‐called negative geotaxis refers to the natural upward climbing behavior of Drosophila melanogaster after it oscillates to the bottom of the test tube. The strength of climbing ability is regarded as the index of aging change of D. melanogaster. At present, many laboratories use the percentage of 10 fruit flies climbing a specific height in 5 s as a general indicator of the climbing ability of fruit flies. This group research index ignores the climbing performance of a single fruit fly, and the climbing height belongs to the concept of vertical distance in physics, which cannot truly and effectively reflect the concept of curve distance in the actual climbing process of fruit flies. Therefore, based on the image processing algorithm, we added an experimental method to draw the climbing trajectory of a single fruit fly. By comparing the differences in climbing behavior of fruit flies under different sex, group or single, oscillation condition or rotation inversion condition, we can find that the K‐Nearest Neighbor target detection algorithm has good applicability in fruit fly climbing experiment, and the climbing ability of fruit flies decreases with age. Under the same experimental conditions, the climbing ability of female fruit flies was greater than that of male fruit flies. The climbing track length of a single fruit fly can better reflect the climbing process of a fruit fly.

ObjectivePersons with immune‐mediated inflammatory diseases (IMIDs) are at an increased risk of herpes zoster (HZ). In 2018, the Centers for Disease Control and Prevention recommended a highly efficacious vaccine, recombinant zoster vaccine (RZV), for prevention of HZ in immunocompetent patients ≥50 years of age. This study was undertaken to estimate RZV vaccination among adults ages ≥50 years with IMIDs during 2018–2019 and to examine possible vaccine‐related flares following RZV.MethodsWe identified a cohort of IMID patients using medical claims data from the IBM MarketScan (ages 50–64 years) and Centers for Medicare and Medicaid Services Medicare (ages ≥65 years) databases. Presumed flares were defined as hospitalization/emergency department visit for their respective IMIDs, or steroid treatment with a short‐acting oral glucocorticoid or parenteral glucocorticoid injection. We conducted a self‐controlled case series (SCCS) analysis to examine a temporal association between RZV and flares.ResultsAmong enrollees with IMIDs, 14.8% of 55,654 MarketScan enrollees and 43.2% of 160,545 Medicare enrollees received ≥1 dose of RZV in 2018–2019. Two‐dose series completion rates were 76.6% in MarketScan enrollees and 85.4% in Medicare enrollees. In the SCCS analysis, 10% and 13% developed flares in the control window, compared to 9% and 11–12% in the risk window following 1 or 2 doses of RZV among MarketScan and Medicare enrollees, respectively. We found no statistically significant increase in flares following RZV administration for any IMID in either age group following RZV dose 1 or dose 2.ConclusionWe did not find an increase in presumed flares following RZV vaccination. Among adults ages ≥50 years with IMIDs, a substantial proportion received RZV compared to general zoster coverage estimates, and series completion rates were high.
Using data citation to define a knowledge domain: A case study of the Add‐Health dataset
Authors: Fan Wei‐Min , Jeng Wei , Tang Muh‐Chyun 
Published: June 2022

AbstractTo date, most studies in scientometric map and track the main topics in a knowledge domain by measuring publications in core journals or keyword searches in databases. The present study instead proposes a novel metrics in which a knowledge domain is mapped and tracked via articles that cite the same openly accessible dataset. We retrieved 1,537 journal articles citing the National Longitudinal Study of Adolescent to Adult Health (Add‐Health) as the basis for an investigation of the major research topics associated with this dataset and how they evolved over time. To identify the primary research interests associated with the dataset, co‐word network modularity analysis was used. Another novel aspect of this study is that it juxtaposes the research topics identified by the co‐word approach with those generated by topic modeling: an approach that complements network modularity analysis, and allows for cross‐referencing between the results of these two methods. Keyness analysis was also performed to identify significant keywords in different time periods, which enables tracing of research interests in Add‐Health as they evolve. The methodological implications of using data citation as the basis for delineating a knowledge domain and techniques for its mapping are also discussed.

Published: June 2022

AbstractThe development of multifunctional nanoplatforms for bioimaging and therapy has attracted extensive attention in recent decades. As an emerging magnetic resonance imaging (MRI) technique, 19F MRI effectively complements the limit of 1H MRI owing to trace amount of 19F atoms existing in the human body, affording high specificity. In this work, a novel molecule (CFO) containing hydrophilic fluorine fragments was synthesized using amino acids as starting materials, which could self‐assemble into small nanoprobes via hydrophobic interactions of oleic acid moiety. The as‐prepared nanoprobes displayed good relaxation performances thanks to the carboxylate group and sulfoxide group nearby. The nanoprobes successfully demonstrated its capacity for in‐vivo 19F MRI. In addition, CFO could be used as a general fluorine labeling agent for surface functionalization of nanoparticles, which provided a universal method for constructing water‐soluble multifunctional nanoplatforms.
