Flexible, stretchable,and transparent InGaN/GaN multiple quantum wells/polyacrylamide hydrogel-based light emitting diodes

Visualization is a direct, efficient, and simple interface method to realize the interaction between human and machine, whereas the flexible display unit, as the major bottleneck, still deeply hinders the advances of wearable and virtual reality devices. To obtain flexible optoelectronic devices, one of the effective methods is to transfer a high-efficient and long-lifetime inorganic optoelectronic film from its rigid epitaxial substrate to a foreign flexible/soft substrate. Additionally, piezo-phototronic effect is a fundamental theory for guiding the design of flexible optoelectronic devices. Herein, we demonstrate a flexible, stretchable, and transparent InGaN/GaN multiple quantum wells(MQWs)/polyacrylamide(PAAM)hydrogel-based light emitting diode coupling with the piezo-phototronic effect. The quantum well energy band and integrated luminous intensity(increased by more than 31.3%)are significantly modulated by external mechanical stimuli in the device. Benefiting from the small Young's modulus of hydrogel and weak Van der Waals force, the composite film can endure an extreme tensile condition of about 21.1% stretching with negligible tensile strains transmitted to the InGaN/GaN MQWs. And the stable photoluminescence characteristics can be observed. Moreover, the hydrogen-bond adsorption and excellent transparency of the hydrogel substrate greatly facilitate the packaging and luminescence of the optoelectronic device. And thus, such a novel integration scheme of inorganic semiconductor materials and organic hydrogel materials would help to guide the robust stretchable optoelectronic devices, and show great potential in emerging wearable devices and virtual reality applications.
Facile fabrication of a single-particle platform with high throughput via substrate surface potential regulated large-spacing nanoparticle assembly

Nanodevices based on the single nanoparticle represent innovative and promising technology, which could satisfy the increasing requirements of high accuracy, low energy consumption, and small volume. However, the acquisition of single particles involves complex operation, and the corresponding nanodevices display low-throughput. Herein, we present a facile strategy to construct a single-particle platform with high throughput via substrate surface potential modulated a large-area and large-spacing nanoparticle assembly. Such platform not only avoids optic interference but also ensures the independent electrically conductive channel of single particle on substrate. Therefore, the dark-field microscopic imaging and single-particle scattering signals collecting of individual nanoparticles with plasmonic effect are satisfactory achieved based on the platform, and the first success in the fabrication of nano-organic-light-emitting-diodes with single nanoparticle resolution in nanoscale. All the results indicate that the strategy may find promising applications in the in situ single-particle research such as single-particle detection, single-particle catalysis, and optoelectronics.
A controllable fabrication improved silicon nanowire array sensor on(111)SOI for accurate bio-analysis application

Silicon nanowire field-effect transistor(SiNW-FET)sensors possess the ability of rapid response, real-time, and label-free detection with high sensitivity and selectivity in the analysis of charged molecules. Their nano-scale size makes them well suited for ultralow detection of charged molecules, but also brings the uniformity fabrication challenging, thus limiting their large-scale application. By a horizontal control approach, highly controllable silicon nanowires arrays at the top of the silicon-on-insulator(SOI)wafer(T-SiNW)were developed in our previous work. To further improve the device uniformity, here a novel SiNW fabricated approach was carefully designed by the combination of horizontal and vertical control. The new silicon nanowires appeared at the bottom of the top silicon layer(B-SiNW). The B-SiNW has a relatively low requirement on the fabrication process and better device uniformity compared to T-SiNW. These improvements resulted in the B-SiNW device with a lower current fluctuation(4.1 nA with 5.1% variations)in the flowing liquid, compared to the T-SiNW device(4.4 nA with 11% variations). Further, in quantitative detection of 40 ng/mL MMP-9, the B-SiNW sensors provided larger signals and lower fluctuation(normalized average response value: 0.57 with 4.2% variations), compared to the T-SiNW sensors(0.41 with 12.1% variations), thus indicating a more accurate bio-analysis application of the B-SiNW sensor. This work advances the nanowire sensor technology a step closer toward large-scale application to create stable sensing platforms in disease diagnosis and monitoring.
Carbon aerogel microspheres with in-situ mineralized TiO_2 for efficient microwave absorption

Carbon aerogels(CAs)have been considered potential microwave absorption(MA)materials because of intrinsic hierarchical porous structure, low density, and excellent heat resistance. However, CAs always required to be ground into micron-scale powder before being used as microwave absorbers, which will inevitably destroy the hierarchical porous structure. Meanwhile, reproducing the optimized CAs powders is difficult. Herein, CAs microspheres with in-situ mineralized TiO_2 were easily prepared via a sol-gel transition and calcination process. The uniform size of CA microspheres and the loaded TiO_2 on the skeleton of CA yield great microwave attenuation performance while guaranteeing good impedance matching performance. The obtained TiO_2/CA hybrid presented a minimum reflection loss value of -30.2 dB and a broad effective absorption bandwidth(reflection loss below -10 dB)of 6.2 GHz. The low density, MA performance, and controllable particle size make the novel TiO_2/CA hybrid promising candidates for MA applications.
Holey graphene oxide-templated construction of nano nickel-based metal-organic framework for highly efficient asymmetric supercapacitor

Metal-organic frameworks (MOFs) with redox-active metal sites and controllable crystalline structures make it possible to access the merits of highly-efficient electrode materials in electrochemical energy storage systems.However,most MOFs suffer from low capacitance and poor cycling stability that largely thwart their application.Herein,we present the holey graphene oxide (HGO) template strategy to prepare nano two-dimensional Ni(BDC) with HGO as both template and capping agent (denoted as Ni(BDC)-HGOx,x = 10,20,30,and 40 according to the added HGO amount).Structural analyses reveal that HGO can significantly inhibit the Ni(BDC) agglomeration,thus offering a high ion-accessible surface area.Ni(BDC)-HGO30 with well-exposed active sites exhibits a high capacitance of 1,115.6 F·g~(-1)at 1 A·g~(-1) in 6 M KOH aqueous,1.8 times that of bulk Ni(BDC).An asymmetric supercapacitor with Ni(BDC)-HGO30 as a positive electrode and activated carbon as the opposing electrode delivers an energy density of 52.5 W·h·kg~(-1) and a power density up to 18.0 kW·kg~(-1),with 92.5% capacitance retention after 10,000 cycles.Galvanostatic intermittent titration technique and in situ electrochemical-Raman measurements were exploited to elucidate the electrochemical behavior of Ni(BDC)-HGO30.These results pave the way for the development of rationally tuned MOF materials for enhancing supercapacitor performances.
Skyrmions-based logic gates in one single nanotrack completely reconstructed via chirality barrier

Logic gates based on magnetic elements are promising candidates for logic-in-memory applications with non-volatile data retention, near-zero leakage and scalability. In such spin-based logic devices, however, the multi-strip structure and fewer functions are obstacles to improving integration and reducing energy consumption. Here we propose a skyrmions-based single-nanotrack logic family including AND, OR, NOT,NAND, NOR, XOR and XNOR that can be implemented and reconstructed by building and switching the Dzyaloshinskii-Moriya interaction(DMI)chirality barrier on a racetrack memory. Besides the pinning effect of the DMI chirality barrier on skyrmions, the annihilation, fusion and shunting of two skyrmions with opposite chirality are also achieved and demonstrated via local reversal of the DMI, which are necessary for the design of an engineer programmable logic nanotrack, transistor and complementary racetrack memory.
Critical review of the impact of cover crops on soil properties

Grasses as well as leguminous and non-leguminous broadleaves are the major categories of commonly grown cover crops worldwide. This review focuses on the contribution of cover crops to soil properties. The review first considers the single and mixed cover crops and shows that grass species are desirable for their decay and ability to provide substantial soil cover, broadleaf species are used for their quick decomposition and capacity of releasing residues into the soil, while the leguminous species are used for their ability to fix atmospheric nitrogen. Secondly, the impacts of cover crops on soil health are reviewed. Integrating cover crops into conventional cropping systems may reduce soil bulk density, improve soil structure and hydraulic properties to facilitate increased water infiltration and storage. Crop residue additions from cover crops may enhance soil organic C and N accretion as well as increase availability of P, K, Ca, Fe and Mg in some soil types under certain climatic conditions. Further, cover crops may provide a better condition for microbial activity, abundance, and diversity. Finally, the review shows that through proper management, cover crops may be utilized as an essential component of soil conservation practices for enhanced soil health. Still, further investigation is necessary to determine cover crop effects in additional cropping systems and climatic zones as well as the long-term effects of cover crops on soil properties, subsequent crop yield, and overall cropping system profitability. This review is an important source of information for crop growers, crop management institutions, universities, and crop consultants for sustainable agricultural production.
Is BMI Associated with Cardiorespiratory Fitness? A Cross-Sectional Analysis Among 8470 Apparently Healthy Subjects Aged 18-94 Years from the Low-Lands Fitness Registry

Objective The purpose of the present study was to investigate the association between cardiorespiratory fitness (CRF) measured as peak oxygen uptake (VO_(2peak),expressed in mL/min) and body mass index (BMI) in a large cohort of apparently healthy subjects.Methods BMI and VO_(2peak) were measured in a cross-sectional study of 8470 apparently healthy adults.VO_(2peak) (mL/min) was determined by an incremental cycle ergometer test to exhaustion.Linear regression analyses were performed to identify predictors of CRF.Results There was no difference in CRF between adults with a normal weight (BMI between 18.5-24.9 kg/m~2) and those who were overweight (BMI 25.0-29.9 kg/m~2).Subjects who were underweight (BMI <18.5 kg/m~2) as well as females who were obese (BMI ≥ 30.0 kg/m~2) showed a reduced CRF compared to the normal and overweight groups.Age,height,and gender were significant predictors of CRF (R~2= 0.467,P <0.0001);BMI did not add significantly to this relationship.Conclusion Our findings indicate that BMI was not associated with CRF in addition to age,height,and gender.In subjects with a BMI <18.5 kg/m~2,CRF was lower compared to subjects with a BMI between 18.5 and 29.9 kg/m~2.In obese subjects,CRF was only lower in females compared to females with a BMI between 18.5 and 29.9 kg/m~2.Correcting CRF for BMI may be beneficial for subjects with a low BMI,and females with a BMI ≥ 30.0 kg/m~2.The outcome of this study might help to improve the interpretation of exercise testing results in individuals with a low or high BMI.
Combining MobileNetV1 and Depthwise Separable convolution bottleneck with Expansion for classifying the freshness of fish eyes

Image classification using Convolutional Neural Network(CNN)achieves optimal performance with a particular strategy. MobileNet reduces the parameter number for learning features by switching from the standard convolution paradigm to the depthwise separable convolution(DSC)paradigm. However, there are not enough features to learn for identifying the freshness of fish eyes. Furthermore, minor variances in features should not require complicated CNN architecture. In this paper, our first contribution proposed DSC Bottleneck with Expansion for learning features of the freshness of fish eyes with a Bottleneck Multiplier. The second contribution proposed Residual Transition to bridge current feature maps and skip connection feature maps to the next convolution block. The third contribution proposed MobileNetV1 Bottleneck with Expansion(MB-BE)for classifying the freshness of fish eyes. The result obtained from the Freshness of the Fish Eyes dataset shows that MBBE outperformed other models such as original MobileNet, VGG16, Densenet, Nasnet Mobile with 63.21% accuracy.
Mechanical joint performances of friction self-piercing riveted carbon fiber reinforced polymer and AZ31B Mg alloy

Carbon fiber reinforced polymer (CFRP) and AZ31B Mg alloy were joined by the friction self-piercing riveting (F-SPR) with different steel rivet shank sizes. With the increase of rivet shank size, lap shear fracture load and mechanical interlock distance increased. Ultrafine grains were formed at the joint in AZ31B as a result of dynamic recrystallization, which contributed to the higher hardness. Fatigue life of the CFRP-AZ31B joint was studied at various peak loads of 0.5, 1, 2, and 3 kN and compared with the resistance spot welded AZ31B-AZ31B from the open literature. The fatigue performance was better at higher peak load (> 2 kN) and comparable to that of resistance spot welding of AZ31B to AZ31B at lower peak loads (< 1 kN). From fractography, the crack initiation for lower peak load (< 1 kN) case was observed at the fretting positions on the top and bottom surfaces of AZ31B sheet. When peak load was increased, fretting between the rivet and the top of AZ31B became more dominant to initiate a crack during fatigue testing.
Comparative study on high temperature deformation behavior and processing maps of Mg-4Zn-1RE-0.5Zr alloy with and without in-situ sub-micron sized TiB_2 reinforcement

Mg-4Zn-1RE-0.5Zr (ZE41) Mg alloy is extensively used in the aerospace and automobile industries. In order to improve the applicability and performance, this alloy was engineered with in-situ TiB_2 reinforcement to form TiB_2/ZE41 composite. The high temperature deformation behavior and manufacturability of the newly developed TiB_2/ZE41 composite and the parent ZE41 Mg alloy were studied via establishing constitutive modeling of flow stress, deformation activation energy and processing map over a temperature range of 250 °C - 450 °C and strain rate range of 0.001 s~(–1) - 10 s~(–1). The predicted flow stress behavior of both materials were found to be well consistent with the experimental values. A significant improvement in activation energy was found in TiB_2/ZE41 composite (171.54 kJ/mol) as compared to the ZE41 alloy (148.15 kJ/mol) due to the dispersed strengthening of in-situ TiB_2 particles. The processing maps were developed via dynamic material modeling. A wider workability domain and higher peak efficiency (45%) were observed in TiB_2/ZE41 composite as compared to ZE41 alloy (41%). The Dynamic recrystallization is found to be the dominating deformation mechanism for both materials; however, particle stimulated nucleation was found to be an additional mode of deformation in TiB_2/ZE41 composite. The twinning and stress induced cracks were observed in both the materials at low temperature and high strain rate. A narrow range of instability zone is found in the present TiB_2/ZE41 composite among the existing published literature on Mg based composites. The detailed microstructural characterization was carried out in both workability and instability domains to establish the governing deformation mechanisms.
Laser-assisted growth of hierarchically architectured 2D MoS_2 crystals on metal substrate for potential energy applications

Recently, there has been substantial interest in the large-scale synthesis of hierarchically architectured transition metal dichalcogenides and designing electrodes for energy conversion and storage applications such as electrocatalysis, rechargeable batteries, and supercapacitors. Here we report a novel hybrid laser-assisted micro/nanopatterning and sulfurization method for rapid manufacturing of hierarchically architectured molybdenum disulfide (MoS_2) layers directly on molybdenum sheets. This laser surface structuring not only provides the ability to design specific micro/nanostructured patterns but also significantly enhances the crystal growth kinetics. Micro and nanoscale characterization methods are employed to study the morphological, structural, and atomistic characteristics of the formed crystals at various laser processing and crystal growth conditions. To compare the performance characteristics of the laser-structured and unstructured samples, Li-ion battery cells are fabricated and their energy storage capacity is measured. The hierarchically architectured MoS_2 crystals show higher performance with specific capacities of about 10 mAh cm~(-2), at a current rate of 0.1 mA cm~(-2). This rapid laser patterning and growth of 2D materials directly on conductive sheets may enable the future large-scale and roll-to-roll manufacturing of energy and sensing devices.
Regulation of fleshy fruit ripening: from transcription factors to epigenetic modifications

Fleshy fruits undergo a complex ripening process, developing organoleptic fruit traits that attract herbivores and maximize seed dispersal. Ripening is the terminal stage of fruit development and involves a series of physiological and biochemical changes. In fleshy fruits, ripening always involves a drastic color change triggered by the accumulation of pigments and degradation of chlorophyll, softening caused by cell wall remodeling, and flavor formation as acids and sugars accumulate alongside volatile compounds. The mechanisms underlying fruit ripening rely on the orchestration of ripening-related transcription factors, plant hormones, and epigenetic modifications. In this review, we discuss current knowledge of the transcription factors that regulate ripening in conjunction with ethylene and environmental signals (light and temperature) in the model plant tomato (Solanum lycopersicum) and other fleshy fruits.We emphasize the critical roles of epigenetic regulation, including DNA methylation and histone modification as well as RNA m 6A modification, which has been studied intensively. This detailed review was compiled to provide a comprehensive description of the regulatory mechanisms of fruit ripening and guide new strategies for its effective manipulation.
BrpNAC895 and BrpABI449 coregulate the transcription of the afflux-type cadmium transporter BrpHMA2 in Brassica parachinensis

Brassica parachinensis is a popular leafy vegetable. It is able to accumulate high concentrations of cadmium (Cd), but the molecular mechanism of Cd accumulation is unknown. This study investigated the function and regulatory mechanism of the Cd-responsive metal ion transporter gene BrpHMA2. BrpHMA2 was induced by Cd stress and specifically expressed in vascular tissues, and the protein was localized in the plasma membrane. Heterologous expression of BrpHMA2 enhanced Cd accumulation and Cd sensitivity in transgenic Arabidopsis and yeast. After Cd stress, the transcription factors BrpNAC895 and BrpABI449, which may recognize the abscisic acid-responsive elements in the BrpHMA2 promoter, were also differentially expressed. The transcriptional regulation of BrpHMA2 was further investigated using the chromatin immunoprecipitation-quantitative PCR (ChIP-qPCR) assay, the electrophoreticmobility shift assay (EMSA), and luciferase (LUC) reporter activity analysis employing the transient expression system of B. parachinensis protoplasts and tobacco leaves and the Escherichia coli expression system. By binding to the promoter, BrpNAC895 induced the transcription of BrpHMA2. BrpABI449 might bind to the BrpHMA2 promoter or interact with BrpNAC895 to interfere with the action of BrpNAC895. The findings suggest that BrpHMA2 is a membrane-based afflux-type Cd transporter involved in Cd~(2+) uptake and long-distance transport in plants. BrpNAC895 and BrpABI449, which function as the transcription activator and repressor, respectively, coregulate BrpHMA2 expression.
Data driven discovery of an analytic formula for the life prediction of Lithium-ion batteries

Predicting the cycle life of Lithium-Ion Batteries (LIBs) remains a great challenge due to their complicated degradation mechanisms.The present work employs an interpretative machine learning of symbolic regression (SR) to discover an analytic formula for LIB life prediction with newly defined features.The novel features are based on the discharging energies under the constant-current (CC) and constant-voltage (CV) modes at every five cycles alternately.The cycle life is affected by the CC-discharging energy at the 15th cycle (E_(15-CCD))and the difference between the CC-discharging energies at the 45th cycle and 95th cycle (Δ_(45-95)).The cycle life highly correlates with a simple indicator (E_(15-CCD)-3)/Δ_(45-95) with a Pearson correlation coefficient of 0.957.The machine learning tools provide a rapid and accurate prediction of cycle life at the early stage.
