Summary: The way firms search for knowledge has a critical impact on their innovation performance and technological evolution, and public policies can influence these search activities. Technology-push policies increase search distance, demand-pull policies decrease it, and the influence of policies on search scope is moderated by the breadth of firms' existing knowledge base.

Summary: Green innovation plays an essential role in China's high-quality development and transformation, and is influenced by demand factors. Both domestic and foreign demand have a promoting effect on green innovation, while the widening income gap constrains it. The impact of demand factors on green innovation varies depending on the region and type of patent, and is accompanied by spatial spillover effects and modulation by market segmentation.

Summary: This study explores the factors influencing the utilization of bio-based fertilizer products (BFPs) from the perspectives of farmers, suppliers, and civil society. The results show a mismatch between the demand and supply of BFPs, with farmers expressing interest in using BFPs that are practical, balanced in nutrient content, and economically profitable, while suppliers face challenges in meeting these demands. Civil society organizations are concerned about potential environmental issues associated with BFPs, but central-level representatives are positive about their potential to solve environmental problems. Policy instruments are needed to promote the adoption of BFPs and consider their contribution to sustainable agriculture.

Summary: Phenalenone and its derivatives have high singlet oxygen generation capacity through photosensitization. Efforts have been made to obtain phenalenones with red-shifted absorption while maintaining the ability to generate singlet oxygen. The presence of a dimethylamino substituent at positions 3 or 6 allows for modulation of singlet oxygen generation capacity and fluorescence. Both compounds show red-shifted absorption compared to phenalenone, with different solvent effects on their absorption and emission properties.

Summary: Sophorolipids are a promising microbial biosurfactant for large-scale industrial production and application. In this study, a combination of genetic engineering and green chemical modification via ozonolysis was used to produce key precursors for the development of a library of sophorolipid derivatives. It was found that ozonolysis in water was beneficial in suppressing the formation of unwanted byproducts, thereby simplifying the synthesis process. This efficient and scalable route provides a safe method for the production of sophoroside precursors.

Summary: Two-dimensional nanoporous covalent organic frameworks (2D COFs) have attracted significant interest due to their wide range of applications. Understanding the layer stacking in 2D COFs and its effect on the structural and electronic properties is crucial. In this study, a detailed density functional theory investigation was carried out on four materials, revealing the optimal slipped AA-stacking configuration and the importance of considering dynamic fluctuations in accurately modeling the stacking configuration. The electronic band structure of COFs was found to be profoundly affected by different stacking configurations, with a decrease in layer offset leading to increased interlayer charge mobility.

Summary: The development of a high-performing aminated catalyst requires the adjustment of interactions between the active site, support, and solvent system. In this study, a pyrrolidine group was immobilized on a swellable polymer resin, leading to favorable interactions between the support and water as a solvent. Despite potential inhibition from iminium species, the catalyst exhibited a high turnover frequency. The solvent's affinity for the support resulted in efficient swelling, which was crucial for the observed catalytic performance.

Summary: Organophosphorus compounds like phosphonamidates have applications in pharmaceuticals and pesticides but their synthesis is challenging. We present a flexible, room temperature synthesis for novel P-alkylphosphonamidates that avoids the need for intermediary purification. Our method utilizes oxalyl chloride and phosphonylaminium salts to catalyze the reactions of phosphonochloridates, resulting in the desired products. This protocol is compatible with primary and secondary amines and various phosphonate esters, and it offers a cheap and safe alternative for ammonia in the synthesis of primary phosphonamidates.

Summary: Sophorolipids are attractive microbial biosurfactants with surface-active and biological properties. However, their commercialization has been limited due to minimal structural variation via fermentation. Chemical modification of sophorolipids allows for the generation of derivatives, enabling a fundamental understanding of structure-activity relationships and high-value applications. This review provides an overview of recent developments in chemical modification and targeted applications of sophorolipids and related microbial glycolipids.

Summary: Covalent triazine frameworks (CTFs) based on polydentate ligands are promising catalyst supports that combine the reactivity of homogeneous catalysts with the robustness and recyclability of heterogeneous ones. In this study, a rhodium (III) complex was immobilized on a bipyridine-based CTF for the transfer hydrogenation of N-heteroarenes in water using sodium formate as the hydrogen source. The immobilized catalyst showed excellent activity for various quinoxalines and other N-heteroarenes, and maintained high activity during recycling, making it suitable for continuous flow synthesis.
