Accurate estimation of gross primary production (GPP, ecosystem level photosynthesis) is critical for monitoring terrestrial ecosystems. However, most of the current models used for GPP estimation are with many unknown parameters and rarely include the effects of soil water stress due to the covariation of soil moisture and air humidity. In addition, grasslands, as the most widely distributed ecosystems in the world, have simple ecosystem structure and are easily affected by soil drought. Therefore, in this paper, we applied photosynthesis-hydrology coordination optimization theory and soil water potential based on soil moisture effect to develop a combined model (PH model) for GPP estimation of grassland ecosystems and used the US-Var grassland ecosystem, one of the FLUXNET sites from January to July 2004 (the driest period in recent years) as an example to validate the model. The results show that the model can effectively track the measured GPP during soil drought period and is better than the result from another commonly used photosynthesis coordination model (P-model) which does not consider the effect of soil drought. Further, we can infer the vegetation photosynthetic capacity parameters including the maximum carboxylation capacity (Vcmax) and the maximum electron-transport capacity (Jmax) under the effect of soil drought. The result also shows that if soil drought is not considered, the photosynthetic capacity parameters of vegetation will be overestimated. These results provide evidence for the application of photosynthesis-hydrology coordination theory in the assessment of ecosystem carbon cycle under the intensified climate changes. © 2024 IEEE.

BiVO4 photocatalyst is one of the effective means to solve environmental pollution. However, the low specific surface area and short photogenerated carrier lifetime of a single BiVO4 seriously restrict its development and practical application. In this study, BiVO4 nanofibers were modified by the combination strategy of doping and semiconductor recombination to enhance their photocatalytic activity. The fibers prepared by electrospinning were subjected to heat treatment to remove organic matter, so as to prepare mesoporous Ni-doped BiVO4 nanofibers. Furthermore, the mesoporous fibrous Z-scheme heterojunction photocatalyst BiVO4-Ni/AgVO3 was successfully fabricated by hydrothermal method. The synergistic effect of mesoporous structure, Ni doping and AgVO3 enabled the catalyst BiVO4-Ni/AgVO3 to obtain an excellent photocatalytic reduction of Cr6+ and degradation of RhB. The photocatalytic reduction efficiency of Cr6+ reached 99.7% at 80 min, and the degradation efficiency of RhB reached 98.6% at 30 min. The successful preparation of Z-scheme heterojunction photocatalyst BiVO4-Ni-1/AgVO3-25 has essential application prospects in photocatalytic degradation of pollutants and reduction and purification of metal ions. © 2022, The Authors.

The ternary sulfide ZnIn 2 S 4 (ZIS) can effectively solve the problems of energy shortage and environmental pollution due to its appropriate band gap and excellent visible light absorption. However, ZIS still has the disadvantages of low separation efficiency and fast recombination, which limit its practical application. Therefore, in order to improve its photocatalytic performance, PtS QDs/ZIS composites were prepared by photodeposition of PtS quantum dots (PtS QDs) on ZIS in this study, and excellent photocatalytic hydrogen evolution rates (20777.07 µmol‧g -1 ‧h -1 ) were obtained, which were 2.4 and 148.4 times higher than those of ZIS-Pt and ZIS, respectively, and the quantum efficiency was 13.25% at 430 nm. Secondly, PtS QDs/ZIS also showed efficient reduction performance and good stability in the catalytic reduction of p-nitrophenol (4-NP), reaching 99.87% at 7 min. One-step photodeposition of PtS QDs provides a new idea for photocatalytic hydrogen production from water splitting and catalytic reduction of pollutants. © 2022, The Authors. All rights reserved.

Bimetallic LaNi-doped silica membranes for hydrogen separation

Metal-doped silica membranes have emerged as a promising strategy to enhance hydrothermal stability and gas separation performance compared to pure silica-based alternatives, yet the range of applicable metal elements and mechanistic roles of dopants within silica matrices remain underexplored. This study pioneers the integration of lanthanum (La) and nickel (Ni) into TEOS-derived SiO2 matrices, creating three distinct architectures: La-SiO2 (covalent networks), Ni-SiO2 (nanocrystalline quantum dots), and LaNi-SiO2 (synergistic hybrid). Structural analyses reveal that La preferentially formed covalent Si-O-La bonds by restructuring the amorphous silica framework, while Ni self-assembled into 2–3 nm NiO dots without phase separation in silica. Density Functional Theory (DFT) simulations confirms La's low formation energy for Si substitution in silica clusters, enabling facile Si-O-La bond formation. This dual-doping strategy achieved uniform metal dispersion: NiO as the quantum dots prevented the excessive aggregation of La–O–Si that increased the surface area, while La dispersed and covered the NiO dots to less cluster that reduced the mesoporous volume ratio. These distinct bimetallic dispersion pattern resulted in a high microporosity with small micropore size, enhancing about 5-fold of H2/N2 permselectivity (127.8 vs. 25.6) for LaNi-SiO2 over pristine SiO2 membranes, alongside a H2 permeance of 1.86 × 10–7 mol m−2 s−1 Pa−1. Performance of H2/N2 also surpassed monometallic analogues (La-SiO2: 37.8;Ni-SiO2: 22.1) at 250 °C. By the synergistic effect of La and Ni through their interactions with SiO2 networks, LaNi-SiO2 membranes displayed high H2 adsorption and N2 prohibition. In the hydrothermal stability test, LaNi-SiO2 membranes maintained stable permeance and permselectivity during 120 h exposure in steam under 200 °C. These findings establish bimetallic doping as a versatile strategy of framework modifier to tailor silica-based membranes toward energy-efficient

Coded aperture snapshot spectral imaging (CASSI) is an effective tool to capture spectral images, which has the advantages of snapshot imaging, high luminous flux, high signal-to-noise ratio and low sampling frequency. However, conventional CASSI generally uses refractive prisms or gratings for spectral dispersion, which leads to the nonlinear dispersion phenomenon and the requirement of large detector chip respectively. To overcome these issues, conventional refractive prisms or gratings are replaced by an axially dispersive diffractive optical element (DOE, i.e., computational optics) together with a RGB Bayer filter (i.e., a color-coded aperture) in this study. Specifically, the spatial-spectral information of a test scene is jointly modulated by the DOE and the Bayer filter integrated with a sensor chip. A fully differentiable imaging model is built based on the principle of diffractive optics and the deep learning technology. Furthermore, an optimization design of the DOE with the coded aperture is realized through an end-to-end approach, the output spectral images of which are restored by a Res-Unet neural network. Several simulation results show that up to 31 high-fidelity spectral bands in the range of 400 to 700 nm with a good spatial and spectral resolution can be recovered by the proposed snapshot system. © 2022 SPIE.

Alkali cations modulating electrostatic field of frustrated Lewis pairs for CO2 electroreduction in neutral medium

Carbon dioxide reduction reaction (CO2RR) on highly reactive frustrated Lewis pairs (FLPs) is a promising avenue for producing high-energy-density fuels from renewable energy. Exploring the effects of alkali metal ions on FLPs electrostatic field in neutral medium is a crucial knot for highly active FLP catalyst development. Here, leveraging the distinct electrochemical stability of In-OH and Bi-OH, we create stable Lewis pairs on the Bi0.5In0.5Oy shell layer of Bi0.5In0.5Oy@Bi3In5 core-shell assembly with coordinatively unsaturated Bi-OVs sites (Lewis acids) and In-OH (Lewis bases) to detect alkali metal ions effects. We find that K+ is able to help electrochemically stable FLPs firstly capture and stabilize protons to protonate to Bi–H Lewis acid and In–OH2 Lewis base due to their strong steric electrostatic field;then CO2 is captured and activated by the protonated FLPs to produce formate with high selectivity. Whereas, Li+, Na+, and Cs+ will inhibit CO2RR and promote the competing hydrogen evolution reaction due to Li+, Na+, and Cs+ breaking steric electrostatic field of FLPs by inhibiting Bi-H formation. Our results verify that modulating electrostatic field of frustrated Lewis pairs by appropriate alkali cations is a promising catalyst design concept for highly selective CO2RR. © 2025 Elsevier B.V.

Fiber metal laminate (FML) are widely used in aerospace and other fields because of their excellent mechanical properties, such as high specific strength, high specific stiffness. However, due to their relatively poor interlaminar properties, the further application of FML was limited. In the paper, a fiber metal laminate with embedded nail structure was designed, and the samples were prepared based on 3D printing technology. Through experimental research and finite element simulation, the mechanical properties of fiber metal laminate with nail structure under compressive load were analyzed. By reasonably setting the number and height of nail structure, the delamination damage could be restrained and the mechanical properties of members could be improved. © 2021 IEEE.

Lensless coaxial digital holographic imaging (LCDHI) has great advantages of wide-field, high resolution and nondestructive measurement. By removing traditional lenses and utilizing a coaxial optical path, the lens-aberration can be avoided and the imaging process is greatly simplified, which is one of the powerful tools for observing of micro components and biological cells. With the help of an open-source hardware and deep learning technology, a simple and portable experimental device based on the principle of lensless coaxial digital holography is designed and set up in this study. In order to avoid the problems of difficult data-acquisition and time-consuming training caused by supervised learning, a deep convolutional neural network (CNN) based on an auto-encoder is embedded into the Gerchberg-Saxton (GS) iterative process of LCDHI to accomplish phase retrieval. Compared with the traditional GS algorithm, more accurate amplitude and phase results can be reconstructed by the proposed low-cost device and the designed CNN through several experiments. © 2022 SPIE.
