Comprehensive comparison on different wavelength selection methods using several near-infrared spectral datasets with different dimensionalities.

NIR spectroscopy is widely used in chemical analysis, agricultural science, food safety, and other fields, but its high dimensionality and data redundancy bring analytical challenges. This study aims to compare the performance of different wavelength selection methods in NIR spectral datasets with different dimensionalities to provide a reference for researchers. The wavelength selection methods in this study were classified into four categories according to their principles, which are partial least squares (PLS) parameter-based methods, intelligent optimization algorithms (IOA)-based methods, model population analysis (MPA)-based methods and wavelength interval selection (WIS) methods.

Rubber intercropping with arboreal and herbaceous species alleviated the global warming potential through the reduction of soil greenhouse gas emissions.

Agroforestry systems are known to enhance soil health and climate resilience, but their impact on greenhouse gas (GHG) emissions in rubber-based agroforestry systems across diverse configurations is not fully understood. Here, six representative rubber-based agroforestry systems (encompassing rubber trees intercropped with arboreal, shrub, and herbaceous species) were selected based on a preliminary investigation, including Hevea brasiliensis intercropping with Alpinia oxyphylla (AOM), Alpinia katsumadai (AKH), Coffea arabica (CAA), Theobroma cacao (TCA), Cinnamomum cassia (CCA), and Pandanus amaryllifolius (PAR), and a rubber monoculture as control (RM). Soil physicochemical properties, enzyme activities, and GHG emission characteristics were determined at 0-20 cm soil depth.

Organic/Inorganic Hybrid Cross-Linked Gel Polymer Electrolyte for Optimizing the Solvation Structure of Lithium Ions.

Lithium metal electrodes inevitably lead to the decomposition of the liquid electrolyte and lithium dendrite growth, both of which result in the formation of unstable solid electrolyte intermediates (SEIs). Gel polymer electrolytes (GPEs) are expected to replace liquid electrolytes for optimizing the SEI issues of lithium metal. Herein, a cellulose-based gel electrolyte cross-linked by thiol-modified polyhedral oligomeric silsesquioxane (thiol-modified-POSS) was successfully obtained based on "thiol-ene" click chemistry.

Molecular engineering of poly(amino)heptazine expands intra-molecular built-in electric field for efficient activation persulfate.

In the manipulation of π-conjugated organic polymer, strategic alterations to the polymerization cascade facilitate the integration of donor (D) and acceptor (A) entities within the polymer's backbone. Such control is instrumental in broadening the photoresponse spectrum, enhancing photoinduced charge separation, and augmenting the efficiency of charge transfer processes. The oxygen-containing amino group (-ONH) was innovatively grafted into the polymerization process of the triazine-heptazine ring skeleton, and the -ONH was used as a capping agent to change the chain bonding in the polymerization process, thus a new intramolecular D-A structure was successfully constructed.

A novel photoelectrochemical biosensor for sensitive detection of nucleic acids based on recombinase polymerase amplification and 3D-array titania nanorods.

Nucleic acids detection is essential for diagnosing pathogens; however, traditional methods usually face challenges such as low sensitivity, lengthy reaction times, and strict temperature requirements. This study develops a novel photoelectrochemical (PEC) biosensor that integrates recombinase polymerase amplification (RPA) with a 3D-array titania (TiO) nanorods nanorod electrode, addressing the challenge of achieving sensitive detection of RPA-amplified nucleic acids products, thereby enabling earlier and more reliable pathogen detection. The biosensor utilizes a triple-binding mode involving FITC antibodies, target nucleic acids, and an HRP-streptavidin sandwich structure, significantly improving the bio-functionalization of the electrode surface.

Balancing methane emission and alkalinity conservation: Insights from mineral amendments in coastal sediments.

With global climate warming and ocean acidification, mineral amendments in coastal areas have emerged as a promising strategy to bolster carbon sinks and alkalinity. However, most research has predominantly focused on carbon dioxide (CO) absorption, with limited exploration of methane (CH) reduction despite its more potent greenhouse effect. To address this gap, our study conducted a microcosm manipulative experiment employing coastal wetlands sediments to elucidate the regulatory effects of various mineral amendments on greenhouse gas emissions (including CO and CH) and seawater alkalinity.

Pd/Cu-TCPP(Fe)-polydopamine mediated magnetic relaxation switching immunosensor for sensitive detection of chlorpyrifos.

This study presents the development of a magnetic relaxation switching (MRS) immunosensor for the sensitive detection of chlorpyrifos (CPF) with a signal amplification strategy using Pd/Cu-TCPP(Fe) hybrid nanosheets and polydopamine (PDA). Pd/Cu-TCPP(Fe) nanosheets, which exhibit high peroxidase-like activity and excellent storage stability, making them suitable replacements for natural enzymes in biosensors, are further functionalized with goat anti-mouse IgG (Ab) to construct an immunosensor. The mechanism relies on the competition between free CPF and the immobilized bovine serum albumin-CPF conjugates for antibody binding, which modulates the aggregation of magnetic nanoparticles (MNPs) that are related to the transverse relaxation time.

The results indicated that Y + T treatment not only reduced decay percentage, weight loss, and pH increase but also preserved the pericarp cell integrity and reduced the lignin accumulation.

Mn Doping at High-Activity Octahedral Vacancies of γ-FeO for Oxygen Reduction Reaction Electrocatalysis in Metal-Air Batteries.

γ-FeO with the intrinsic cation vacancies is an ideal substrate for heteroatom doping into the highly active octahedral sites in spinel oxide catalysts. However, it is still a challenge to confirm the vacancy location of γ-FeO through experiments and obtain enhanced catalytic performance by preferential occupation of octahedral sites for heteroatom doping. Here, a Mn-doped γ-FeO incorporated with carbon nanotubes catalyst was developed to successfully achieve preferential doping into highly active octahedral sites by employing γ-FeO as the precursor.

The application of solid oxide electrolysis cells (SOECs) for high-temperature CO reduction reaction (CORR) is constrained by the electrochemical activity and stability of the cathode materials. In this study, a series of iron-based perovskite oxides, designed by systematically varying A-site configurational entropy, are investigated as cathode materials for the CORR. Experimental results reveal that these high-entropy materials, derived from LaSrFeO (LSF), exhibit high electrocatalytic activity and durability.

Decelerating and Accelerating Sulfur Reduction Reaction via P-O-InO Enables High-Performance Li-S Batteries.

The sluggish sulfur reduction reaction (SRR) kinetics of lithium-sulfur (Li-S) batteries seriously limits the development of Li-S batteries. The initial reduction of solid (S) to liquid (soluble LiS (4≤n≤8)) is relatively easy due to the low activation energy, whereas the subsequent conversion of liquid (soluble LiS) to solid (insoluble LiS/LiS) has much higher activation energy, which leads to the accumulation of LiS and exacerbates the shuttle effect of LiS. Therefore, establishing one selective catalyst that decelerates the previous solid-liquid reaction and accelerates the subsequent liquid-solid reaction is essential for rational tailoring of the SRR for improved performance of Li-S batteries, but it represents a daunting challenge.
