AbstractPotassium (K)‐based layered oxides are potential candidates for K‐ion storage but they suffer from chemical instability under ambient conditions that deteriorate their performance in rate‐capability and cycle life. To tackle this issue, a facile hydration strategy is employed, in which H2O molecules are introduced into the K ion layers of P3‐type K0.4Fe0.1Mn0.8Ti0.1O2, which induces a phase transition from the hexagonal to monoclinic symmetry accompanied by layer spacing expansion. The hydrated K0.4Fe0.1Mn0.8Ti0.1O2 ⋅ 0.16H2O has a strong tolerance to air and can be stored in lab air ambient for 60 days without a change in crystal structure or chemical composition. The K0.4Fe0.1Mn0.8Ti0.1O2 ⋅ 0.16H2O electrode shows improved K+ mobility and less volume change during potassiation/de‐potassiation. Owing to these merits, K0.4Fe0.1Mn0.8Ti0.1O2 ⋅ 0.16H2O as the cathodes for both organic and aqueous potassium‐ion full batteries attain outstanding rate capability and cycling stability (for example, capacity retention of 90% after 1000 cycles). This simple and potent hydration strategy has also been applied to improve the air stability of other K‐based layered oxides, including P3‐K0.4MnO2 and P2‐K0.5Cu0.1Fe0.1Mn0.8O2, illustrating its usefulness in boosting layered oxides for durable potassium‐ion storage.

Abstract2D materials, with their extraordinary physical and chemical properties, have gained extensive interest for physical, chemical and biological sensing applications. However, 2D material‐based devices, such as field effect transistors (FETs) often show high contact resistance and low output signals, which severely affect their sensing performance. In this study, a new strategy is developed to combine metallic and semiconducting polymorphs of transition‐metal dichalcogenides (TMDCs) to solve this critical issue. Such a phase engineering methodology to integrate large‐scale and spatially assembled multilayers of 2H MoTe2 FETs with coplanar metallic 1T′ MoTe2 contacts is applied. Such in‐plane heterophase‐based FETs exhibit an ohmic contact behavior with an extremely low contact resistance due to the coplanar and seamless connections between 2H and 1T′ phases of MoTe2. These 1T′/2H/1T′ based FETs are successfully demonstrated for detecting NH3 with high current outputs increased up to microamp levels without using any conventional interdigital electrodes, which is compatible with the current CMOS circuits for practical applications. Furthermore, the as‐fabricated sensors can detect NH3 gas concentrations down to 5 ppm at room temperature. This study demonstrates a new strategy of applying the heterophase MoTe2‐based nanoelectronics for high‐performance sensing applications.

AbstractConductive hydrogels generally possess dual network structures consisting of hydrophilic cross‐linked polymer frameworks and conductive paths. The post‐modification of their structures and performance for fabricating devices with 3D conductive patterns is challenging because of their covalently cross‐linked complex matrices. Here, an orthogonal‐growth strategy is described for modulating all‐aspects of conductive hydrogels, including size, pattern, conductivity, and conductive path. In this strategy, the matrices controlling samples’ size and the functional components modulating samples’ conductivity can be orthogonally varied by feeding corresponding nutrients. Using poly(hydroxyethyl acrylate)‐polyaniline organohydrogels (PHEA‐PANI) as an example, it is demonstrated that the samples can incorporate the hydroxyethyl acrylate monomer to expand (21.9‐fold in weight is shown) or integrate aniline into the conductive networks to tune conductivity (from 0 to 42.6 mS cm‐1) without changing the sample size. Moreover, the growth of PANI is spatially selective. Exploiting the selective modulation of various parameters through this method, strain sensors with post‐modulated sensing performance and 3D hydrogel circuit boards are fabricated.

AbstractHole transport materials (HTMs) are of great significance to improve the efficiency and long‐term stability of perovskite solar cells (PVSCs). Herein, a series of new HTMs based on isomeric dithienothiophene (DTT) are designed and synthesized. Effects of sulphur (S) atoms positions on defect passivation and performance of PVSCs are systematically investigated through theoretical computation, X‐ray diffraction, X‐ray photoelectron spectroscopy, etc. The three molecules display noticeable isomeric effect in energy level, light absorption, and hole mobility. With S atoms varied from bottom‐bottom‐bottom in 3T‐1 to bottom‐bottom‐top in 3T‐2, then to bottom‐top‐bottom in 3T‐3, the grown perovskite crystallite on the corresponding HTMs shows more homeogenous film morphology and less pinhole traps. Meanwhile, nonradiative recombination losses can be suppressed and hole extraction efficiency at HTM/perovskite surface can be improved from 3T‐1 to 3T‐3. As a result, the remarkable improvement of short‐circuit current density nd open‐circuit voltage in inverted perovskite solar cells can be realized with increasing the sulphur atoms contribution to the molecular conjugation. More importantly, 3T‐3‐based dopant‐free HTM achieves a top power conversion efficiency of 19.23% in PVSCs with good device stability under green solvent processing. These results demonstrate the role of S atoms positions in HTMs on photovoltaic performance of PVSCs and the potential of DTT in developing eco‐friendly HTMs toward efficient PVSCs.

AbstractSimultaneous passivation of the defects at the surface and grain boundaries of perovskite films is crucial to achieve efficient and stable perovskite solar cells (PSCs). It is highly desirable to accomplish the above passivation through rational engineering of hole transport materials (HTMs) in combination with appropriate procedure optimization. Here, methylthiotriphenylamine‐substituted copper phthalocyanine (SMe‐TPA‐CuPc) is reported as a dopant‐free HTM for PSCs, exhibiting excellent efficiency, and stability. After thermal annealing, SMe‐TPA‐CuPc molecules diffused into the bulk of the perovskite film and effectively passivated the defects in the bulk and at the interface of the perovskite, owing to the strong interaction between the methylthio moiety and undercoordinated lead. The best‐performing annealed SMe‐TPA‐CuPc‐based device shows efficiency of 21.51%, which is higher than the unannealed SMe‐TPA‐CuPc‐based device (power‐conversion efficiency (PCE) of 20.75%) and reference doped spiro‐OMeTAD‐based device (PCE of 20.61%). Further modification of the perovskite of the annealed SMe‐TPA‐CuPc‐based device by the QAPyBF4 additive result in even higher efficiency of 23.0%. It also shows excellent stability, maintaining 96% of its initial efficiency after 3624 h aging at 85 °C. This work highlights the great potential of phthalocyanine‐based dopant‐free HTMs and the defect passivation by thermal‐induced molecular diffusion strategy for developing highly efficient and stable PSCs.

AbstractMultilevel (or multistate) electrochromic devices have the potential to achieve highly compact memory capacity while instantaneously transferring data between memory and processing units. In this article, three novel solution‐processable ruthenium‐polymetallaynes (i.e., P1, P2, and P3), in which the redox‐addressable Ru center is covalently embedded into a conjugated organic polymer, are discussed. In pursuit of higher functionality (e.g., stable multistate behavior, low operating voltage), the organic ligand bridging the metal centers is systematically varied. The previously reported P1 has a bithiophene (BT) bridging ligand with a high degree of rotational freedom. By replacing BT with cyclopenta‐dithiophene in P2 and dithieno‐pyrrole (DTP) in P3, both of which are more planar than BT, the degree of freedom is decreased. By using DTP, redox‐matching is achieved between the metal center and organic ligand, leading to extra stability of the mixed‐valence (MV) state in P3. In‐depth experimental (i.e., in situ electron paramagnetic resonance and UV–vis–NIR spectroelectrochemistry) and theoretical studies (i.e., DFT calculations) are carried out on the polymer thin‐films, showing enhanced metal–metal (M–M) interaction in P2 and P3 and stable Robin–Day class III MV compound in P3. These polymers are also first time fabricated into solid‐state electrochromic devices and the stability of each oxidation state is characterized by tracing the change of transmittance over time, showing satisfactory cyclic stability and retention behavior (≈90% retention after 30 min).

AbstractIn recent years, inorganic lead halide perovskite quantum dots have been used in various optoelectronic fields for their excellent luminescence properties, such as narrow emission bands, ultra‐wide tunable emission wavelength, and high quantum efficiency. In this paper, different from luminescence optimization in most research, luminescence degradation of perovskite quantum dots is addressed by femtosecond laser irradiation and successfully used for three‐dimensional data storage in CsPbBr3 quantum dots doped glass. Photoluminescence (PL) degradation can be finely modulated by adjusting the laser parameters. PL degradation mechanism, investigated by optical spectroscopy and morphology characterization, is attributed to laser‐induced decomposition, recrystallization, and defection of CsPbBr3 quantum dots. Laser‐induced PL degradation and the followed PL recovery by heat treatment are repeated for several cycles, showing good reversibility. Multilayer PL degradation patterns are written into the glass and read out without crosstalk, indicating high‐reliability 3D optical storage characteristics. Amazingly, PL degradation can be induced by just a low‐energy single laser pulse with estimated subpicosecond writing time per bit, demonstrating its potential in high‐speed, low‐power consumption 3D optical storage.

AbstractHerein, we report the synthesis of a series of π‐expanded coumarin derivatives by the selective C−H alkenylation of β‐naphthol in the presence of a palladium catalyst. The use of an anionic thioether ligand is critical for ensuring the high reactivity of this reaction; it enables low catalyst loadings, mild reaction conditions, and the use of acetic acid as a green solvent. This chemistry is widely applicable to naphthol‐based aromatic substrates bearing either electron‐donating or ‐withdrawing functional groups.magnified image

Published: August 2022

AbstractAs nanoelectronic devices based on 2D materials are moving toward maturity, optimization of the properties of the active 2D material must be accompanied by equal attention to optimizing the properties of and the interfaces to the other materials around it, such as electrodes, gate dielectrics, and the substrate. While these are usually either 2D or 3D materials, recently K. Liu et al. [Nat. Electron. 4, 906 (2021)] reported on the use of 0D material, consisting of vdW‐bonded Sb2O3 clusters, as a highly promising insulating substrate and gate dielectric. Here, a computational screening study to find promising 0D materials for use in nanoelectronics applications, in conjunction with 2D materials in particular, is reported. By combining a database and literature searches, 16 materials belonging to 6 structural prototypes are found with high melting points and high band gaps, and a range of static dielectric constants. Additional first‐principles calculations are carried out to evaluate selected technologically relevant material properties, and it is confirmed that all these materials are van der Waals‐bonded, thus allowing for facile separation of 0D clusters from the 3D host and only weakly perturbing the electronic properties of the 2D material after deposition.

Abstract2D Weyl semimetal shows potential applications in photodetection, polarization‐sensitive imaging, and Schottky barrier diodes, due to its unique band structure and topological nature. However, its inherently large dark current hinders further improvements of the Weyl semimetal‐based photodetector's performance. Herein, a Td‐TaIrTe4/n‐type MoS2 van der Waals (vdWs) heterojunction photodetector is reported. Owing to the effective lateral build‐in electric field of 145.3 meV, the Schottky diode shows a high rectification ratio of 6 × 103. Benefiting from the photovoltaic effect, a maximum responsivity (R) of 750 mA W−1 and an Ion/Ioff ratio of 104 under 635 nm illumination are achieved. What's more, the photovoltaic R can be enhanced to 890 mA W−1 at the Vg of 40 V. Because of the highly anisotropic crystalline structure of TaIrTe4 component, a high self‐powered photocurrent anisotropic ratio up to 4.19 is realized under 635 nm light at Vg = 40 V. Under self‐powered mode, a high‐resolution letter of “T” within 150 × 120 pixels can be displayed when the polarization direction is parallel to the armchair direction, while it becomes weak along the zigzag direction. This work provides a valuable route to fabricate anisotropic Weyl semimetal/semiconductor vdWs junction for highly integrated optoelectronics.

AbstractOverseeding annual ryegrass [Lolium perenne L. ssp. multiflorum (Lam.)] into warm‐season grass pasture is a common practice producing almost year‐round forage for cow–calf operations in the southern United States. Such an approach requires continuous soil nutrient availability throughout the season for consistent forage production. Coated fertilizers marketed as “slow‐release” may be an efficient and continuous plant nutrient source. Therefore, a study was conducted to investigate the impact of fertilization options targeting sustainable nutrient release on year‐round dry matter (DM) production. Research was conducted to determine fertilization effects of split application of uncoated inorganic fertilizer, slow‐release coated fertilizer, broiler litter, and zero‐fertilizer on forage production and nutritive value of annual ryegrass overseeded bahiagrass (Paspalum notatum Fluegge) pasture. The slow‐release coated fertilizer produced more total forage mass (30 Mg ha–1), which was of higher crude protein during spring (≥200 g dry matter [DM] kg–1), than the other treatments (<23 Mg ha–1 and 173 g DM kg–1, P < .05). The broiler litter and split application of uncoated inorganic fertilizer produced similar amounts of forage DM. The N uptake from the slow‐release coated fertilizer was higher than the other treatments until mid‐summer. Although early spring‐applied slow‐release fertilizer can enhance total forage production and quality indicators, high cost limits revenue above variable cost of this slow‐release fertilizer to levels similar to that of split‐applied uncoated inorganic N, with broiler litter providing the more economic supply of N to pastures with long growing seasons.

AbstractBackgroundEarly menopausal onset can increase adverse health outcomes in later life; meanwhile, reproductive experiences before menopause may affect its timing. Framed by life course methodology, the study tested for independent and interdependent associations between reproductive history (contraception, age at first birth, parity, terminated pregnancy) and socioeconomic factors (education, wealth, rural–urban residence, cigarette use, marital status, age at first cohabitation) with the occurrence of early menopause.MethodsThe study population was ever‐married women aged 40–49 from the 2016 Demographic & Health Survey (N = 2748). Analytical methods involved probability‐ and age‐adjusted multivariate logistic regression models and predictive margins.ResultsConnections between reproductive and socioeconomic characteristics were key dynamics associated with menopause in ages 40–49. Contraception, parity, and ages at first birth and marriage were found to be independently associated with menopause in this age group. Evidence of interactions was found where no contraceptive use was associated with higher probabilities of menopause for first‐time mothers aged 12–15 and for women with no education.ConclusionsStudying Ugandan women's reproductive histories highlighted the importance of regional knowledge about menopause. Though we hypothesized that risks would correlate in a chain, the results pointed to risks clustering around contraception, suggesting that improving contraceptive use and education for women could increase menopausal age. Furthermore, the positive association between low parity and early menopause supports the biological mechanism of faster oocyte depletion; however, high‐parity populations like Uganda tend to have a younger menopausal age than low‐parity populations. Declining mortality in the demographic transition could explain these inverse associations.

AbstractObjectiveThe objective of this study was to determine the feasibility of collecting occupation and occupational hazard data in a primary care setting, using the Occupational Information Network (O*NET) database to assist with classification.MethodsWe collected data from 204 employed adult primary care patients in Toronto, Canada, on their occupation and exposure to occupational hazards, and mapped their job titles to the O*NET database. We compared their self‐reported occupational hazard exposures with the likelihood of exposure on O*NET.ResultsExposure to repetitive arm movement was reported by 78%, to vapors/gas/dust/fumes by 30%, to noise by 30%, and to heavy loads by 31%. Significant differences in exposure to vapors/gas/dust/fumes were associated with work precarity. We matched the majority of job titles (89%) to O*NET categories.ConclusionsCollecting employment information in primary care setting was feasible, with the majority of job titles mapping onto O*NET classifications.

Published: August 2022

AbstractDuchenne muscular dystrophy (DMD) is a progressive, fatal neuromuscular disorder typically diagnosed between 4 and 5 years of age. DMD currently has five FDA approved therapies, which has led to increased interest in newborn screening (NBS) for DMD. Our objective was to explore the perspectives and predicted practices of physicians (primarily neurologists) who will likely be responsible for the follow‐up of infants identified with DMD through NBS. A short survey was developed and distributed to physicians who are responsible for providing care for patients with Duchenne at Certified Duchenne Care Centers across the USA. Twenty‐seven physicians responded to statements about benefit and readiness for dystrophinopathy NBS, which care recommendations they would make at initial infant visits, and when they would recommend initiating approved therapies. Most DMD physicians indicated they see benefit in NBS (82%) and believe the DMD care community is ready for NBS in dystrophinopathies (74%). The majority of physicians would recommend multiple interventions, including genetic counseling, maternal carrier testing, referral to early intervention services, screening siblings, discussion of clinical trials, exon skipping therapies, and assessment of social and language development at initial visits. The majority of physicians also indicated they would recommend initiating approved therapies much earlier than the typical age of diagnosis.
