In this study, we developed an approach to enhance the separation and transfer of charge carriers for photoelectrochemical water splitting in solar-driven hydrogen production. We achieved this by designing a highly efficient Z-scheme TiO2/g-C3N4/ZnO photoanode. The process involved electrodepositing a thin TiO2 layer on FTO and optimizing the in situ ZnO implantation onto g-C3N4. These composites were confirmed by XRD, SEM, EDX, and TEM measurements. The growth of ZnO on g-C3N4 resulted in strong chemical adhesion between the interface of ZnO and g-C3N4, as supported by XPS data, and increased active surface area, as demonstrated by BET. The composition of ZnO and g-C3N4 facilitated rapid charge separation and retarded change recombination through directional charge migration and decreased charge resistance, as evidenced by PEIS and TRPL measurements. Our airbrushing procedure for fabricating the g-C3N4/ZnO composite on TiO2 also enhanced the charge collection efficiency, enabling us to construct a high-performance photoanode. The Z-scheme-type charge migration route was verified by EPR spectroscopy by trapping the radicals generated by charges and holes. PEC-WS measurements showed that TiO2/g-C3N4/ZnO heterostructure improved the produced photocurrent by about 160-, 40-, 20-, 8-, 2-, and 2-fold, relative to pristine g-C3N4, pristine ZnO nanorods, ZnO/g-C3N4 composite, pristine TiO2, TiO2/ZnO, and TiO2/g-C3N4, respectively, versus reversible hydrogen electrode (RHE) at 1.23 V. The charge carriers’ separation and injection measurements showed that the fabrication of this ternary photoanode remarkably improved the PEC-WS performance. DFT results contributed to a deeper understanding of the mechanism of the photocatalytic process and confirmed that the as-fabricated ternary heterojunction promoted the separation/transfer efficiency of the photogenerated charge carriers, thereby promoting the activity of the photocatalytic process.

Food Bioscience 2024年 62卷

作者： Cruz, Josias Martins dos Anjos Corrêa, Renilto Frota Sanches, Edgar Aparecido Campelo, Pedro Henrique Bezerra, Jaqueline de Araújo Center for Studies in Science and Technology in the Amazon (NECTAM) Amazonas Manaus Brazil Graduate Program in Chemistry Federal University of Amazonas (UFAM) Amazonas Manaus Brazil Laboratory of Nanostructured Polymers Federal University of Amazonas (UFAM) Amazonas Manaus Brazil Department of Food Technology Federal University of Viçosa (UFV) Minas Gerais Viçosa Brazil

The Amazon is rich in fruits that are primarily used by the local population for food purposes. In addition to their nutritional benefits, they are also important for the economic development of the region. In recent years, these fruits have attracted considerable attention from researchers due to their chemical composition, properties, and potential applications. The aim of this study was to analyze the research trends surrounding Amazonian fruits. The documents used in this review include 75 research articles (identified through the Ordinatio index) retrieved from Scopus, and 21 patents retrieved from Google Patents and Espacenet, focusing on the use of Amazonian fruits in food technology. Amazonian fruits have been explored for their content of phenolic compounds (especially anthocyanins), carotenoids, vitamins (mainly ascorbic acid), oils, and fibers, all of which are associated with various bioactivities. In addition to the pulp, the waste generated from these fruits also contains chemical constituents with high potential, although they are usually discarded. Therefore, there is a need for discussion among different industrial and governmental sectors to implement production chains, generate income, and provide appropriate disposal for the by-products generated during the processing of Amazonian fruits, thus contributing to sustainable economic development in the Amazon. However, in general, it is observed that although many interesting results have been published, much of the academic knowledge produced has yet to be converted into income generation, mainly through the patenting of products and processes. This may be linked to a lack of investment and/or interest/awareness from the researchers themselves. © 2024

The goal of this paper is to make a fully automatic bowling pinsetter with VEX IQ. We used motors, sensors and parts of VEX IQ to create a bowling mechanism that was originally operated by metal and pneumatic cylinders. In this paper, it is necessary to overcome the small hardness of plastic parts and the need for a stable bracket to support larger works. It is also necessary to overcome the horsepower output of the VEX IQ motor to drive each structure. And use the sensor setting position and programming to make up for the problem of the VEX IQ host being unable to connect to each other.

The aim of the current study was to provide a review of recent developments in solar desalination from the viewpoint of environmental, regulatory, and economic aspects. The analysis attempted to give better insight into the larger question of why more solar desalination plants are not being established by reviewing different technologies, drivers, barriers, and markets. Critical barriers which were dependent on the level of regional development were found to be uncertainty of government subsidies and a lack of regulatory policies. A new tool called a Pareto frontier may be utilized to generate optimal points in complex scenarios with a high number of variables. This all-inclusive method should be employed in any major decision-making process. Furthermore, in exciting innovative research studies, a sustainable Janus wood evaporator was developed that overcame many of the current solar desalination problems. While subsidies were crucial in the growth of renewable energy programs, barriers in deployment of solar desalination systems still exist such as low electricity tariff structures and fragmented energy policies. The overall trend was towards integration of renewable energy with conventional sources and energy storage systems. © 2023 The Author(s)

热带森林因其生物量巨大、结构复杂和生物多样而著称。然而,关于这些森林光合作用的季节动态及其少水期间的生态适应仍知之甚少。本文利用中南半岛上跨20个纬度(2°-22°N)的自然梯度带,探讨了季节性水分条件变化对中南半岛热带森林光合作用季节动态的影响及其机理。研究结果表明,对于气候季节性明显的热带森林,不论其为常绿、落叶还是半落叶,其雨季的森林冠层光合作用(或称总初级生产总值,GPP)明显高于旱季。缺乏气候季节性的常湿热带雨林,GPP呈现“双峰”季节格局;而且,这种季节格局与太阳辐射之间有较好的对应关系。旱季或者是短干旱期内,冠层导度(Gs)有明显下降,显示出水分对气孔开度的抑制作用。然而,这种气孔开度的降低,并未导致近赤道的常湿低地雨林GPP的下降。也就是说,常湿低地雨林GPP在季节尺度上,表现为光限制而非水分限制。气候季节性明显的3个站点,不论Gs还是GPP在旱季明显低于雨季,则表现出明显的水分限制。

Ascertaining the function of in-plane intrinsic defects and edge atoms is necessary for developing efficient low-dimensional photocatalysts. We report the wireless photocatalytic CO2 reduction to CH4 over reconstructed edge atoms of monolayer 2H-WSe2 artificial leaves. Our first-principles calculations demonstrate that reconstructed and imperfect edge configurations enable CO2 binding to form linear and bent molecules. Experimental results show that the solar-to-fuel quantum efficiency is a reciprocal function of the flake size. It also indicates that the consumed electron rate per edge atom is two orders of magnitude larger than the in-plane intrinsic defects. Further, nanoscale redox mapping at the monolayer WSe2–liquid interface confirms that the edge is the most preferred region for charge transfer. Our results pave the way for designing a new class of monolayer transition metal dichalcogenides with reconstructed edges as a non-precious co-catalyst for wired or wireless hydrogen evolution or CO2 reduction reactions. Systematically study of in-plane intrinsic defects and edge atoms is important to guide the design of low-dimensional photocatalysts. Here the authors investigate photocatalytic CO2 reduction to CH4 over reconstructed edge atoms of monolayer semiconducting WSe2.

This paper proposes a simple Convolutional Neural Network (CNN) program to classify epileptic seizure. The diagnosis of epileptic seizure involves the identification and different characteristic of the Electroencephalography (EEG) signal. As such, it needs a method for identifying and classifying epileptic seizure. Deep learning is part of a neural network that has the ability and pattern to identify and classify epileptic seizure. CNN has been demonstrated high performance on image classification and pattern detection. In this paper, we combine the continuous wavelet transform (CWT) and CNN to classify epileptic seizure. This experiment uses the wavelet transform to convert signal data of EEG to time-frequency domain images. The output of the wavelet transform is an image that will classify into five attributes. In this experiment, we develop a simple program that will compare with other CNN approach (AlexNet and GoogleNet). The results of this experiment are two kinds of data, accuracy, and loss. The resulting accuracy is 72.49%, and the loss is 0.576. This result has a better learning time than GoogleNet and smaller loss result than AlexNet. © Published under licence by IOP Publishing Ltd.

Two tissue-equivalent bromine-based PRESAGE ® dosimeters were fabricated in-house with and without gold nanoparticles (GNPs). The radical initiators used in the two formulas, F1 and F2, were 1,1,1,2-tetrabromoethane and tetrabromomethane, respectively. The aim of this study is to investigate the dependence of radiosensitization on PRESAGE ® formula, GNP concentrations and size, and irradiation energy. Their optical density changes pre- and post-irradiation of 150 kVp and 6 MV X-rays were measured with and without GNPs using a spectrophotometer. Dose enhancement factors of 150 kVp for 0.125, 0.25 and 0.5 mM of 50 nm-GNPs were 1.23, 1.26 and 1.27, respectively, measured by F1. The same factors were 1.20, 1.33 and 1.45 measured by F2. About 4% and 2% dose enhancement of 6 MV at 0.25 mM of 50 nm-GNPs were measured by F1 and F2, respectively. The dose enhancement of 150 kVp at 0.25 mM of 5 nm-GNP was 1.6 measured by F1. The dependencies observed in the two formulas were confirmed by Monte Carlo simulations. The tissue-equivalent bromine-based PRESAGE ® dosimeters can be used to estimate dose enhancement of X-rays which was shown to be dependent on PRESAGE ® formula, radiation energy, GNPs concentration and size. © 2022, The Authors.
