Automated Machine Learning of Interfacial Interaction Descriptors and Energies in Metal-Catalyzed N and CO Reduction Reactions.

Langmuir

January 2025

State Key Laboratory of Coordination Chemistry, Key Laboratory of Mesoscopic Chemistry of Ministry of Education, School of Chemistry and Chemical Engineering, Nanjing University, Nanjing 210023, P. R. China.

The applications of machine learning (ML) in complex interfacial interactions are hindered by the time-consuming process of manual feature selection and model construction. An automated ML program was implemented with four subsequent steps: data distribution analysis, dimensionality reduction and clustering, feature selection, and model optimization. Without the need of manual intervention, the descriptors of metal charge variance (Δ) and electronegativity of substrate (χ) and metal (δχ) were raised up with good performance in predicting electrochemical reaction energies for both nitrogen reduction reaction (NRR) and CO reduction reaction (CORR) on metal-zeolites and MoS surfaces.

Herein, a relay strategy incorporating oxidative cross dehydrogenative coupling (CDC) and N- to N-isomerization is disclosed for the formal N-selective alkylation of triazoles with ethers under thermodynamic control conditions. By taking advantage of the different thermodynamical stabilities of N- and N-alkylated triazoles (3.65 kcal/mol), the initially formed N-isomers can be converted into their more stable N-isomers when reaching thermodynamic equilibrium.

In this study, MAPbBr was encapsulated within a porous metal-organic framework (CAU-17) ligand-assisted reprecipitation, which enhanced the perovskite's photocatalytic stability. This encapsulation approach not only stabilises the photocatalytic performance of MAPbBr but also enables further enhancement of its catalytic efficiency through halogen anion group modification. Results from various characterisation demonstrate that the CAU-17/MAPbBrCl composites possess excellent properties, achieving a tetracycline degradation efficiency of up to 92%.

A backtracking heuristic algorithm for two-dimensional strip packing with rotation.

Sci Prog

January 2025

School of Mechanical & Electrical Engineering, Henan University of Technology, Zhengzhou, China.

A backtracking heuristic algorithm (BHA) was proposed for a two-dimensional rectangular strip packing problem with rotations and without guillotine cutting, which has many applications. An improved fitness strategy was used to select the fittest rectangle to be packed on a strip with a certain height. Next, a backtracking constructive heuristic was repeatedly used at a higher height until all the rectangles were packed.

Bioimaging probes based on carbon dots (CDs) can become a useful replacement for existing commercial probes, benefiting clinical diagnostics. While the development of dual-mode CD-based probes for magnetic resonance imaging (MRI), which provides the ability for photoluminescence (PL) detection at the same time, is ongoing, several challenges have to be addressed. First, most of the CD-based probes still emit at shorter wavelengths (blue/green spectral range), which is harmful to biological objects or have very low PL intensity in the biological window of tissue transparency (red/near-infrared spectral range).

Nanoscale

January 2025

Department of Chemistry and Shanghai Key Laboratory of Molecular and Catalysis and Innovative Materials, Fudan University, Shanghai 200438, P. R. China.

Carbon dots (CDs) are new types of fluorescent nanomaterials with particle diameters of 1∼10 nm and have excellent photoluminescence (PL) properties, good biocompatibility, simple preparation methods and numerous raw materials; consequently, they are promising in the biomedical field. In recent years, to overcome drug resistance and toxic side effects of traditional organic drugs, the synthesis of CDs from drug molecules has become an effective strategy, which produces CDs with the same therapeutic effects as the raw drugs and even possessing new properties. At present, many CDs derived from organic drugs have been developed, which can be classified according to their sources such as antibiotics, anti-inflammatory drugs, and guanidine drugs.

The article proposes a robust approach to jointly modeling multiple repeated clinical measures with intricate features. More specifically, we aim to expand the scope of the multivariate linear mixed model by using the multivariate contaminated normal distribution. The proposed model, called the multivariate contaminated normal linear mixed model with censored and missing responses (MCNLMM-CM), is designed to handle minor outliers effectively, while simultaneously accommodating censored measurements and intermittent missing responses.
