Summary: In this study, we report the large-scale synthesis of photoluminescent single-chain nanoparticles through electrostatic-mediated intramolecular crosslinking in a concentrated solution. The photoluminescent properties of these nanoparticles are strong in the visible range when non-emissive units are confined within them. The composition and microstructure of these nanoparticles can be controlled, making them useful for selectively illuminating interfacial membranes and stabilizing emulsions.

Summary: The research demonstrates the feasibility of synthesizing ammonia under low temperature and pressure conditions using a mechanochemical method, resulting in a higher concentration of ammonia compared to traditional high temperature and pressure synthesis methods.Mechanochemically induced high defect density and violent impact on the iron catalyst were responsible for the mild synthesis conditions.

Summary: In this study, a new method for ammonia synthesis under mild conditions was reported, which involves the confinement of iron single-site catalyst within the graphene lattice and promotion by alkali metal. The catalyst exhibited high activity and the evolution of iron sites during the reaction was characterized. These findings provide important guidance for the development of more active catalysts for ammonia synthesis.

Summary: Over 100 non-canonical nucleotides have been discovered in DNA and RNA, many of which are sensitive to nucleophiles. However, the current oligonucleotide synthesis technologies require nucleophilic conditions for deprotection, making it unsuitable for their synthesis. A recently disclosed method using Dim for phosphate protection and Dmoc for amino protection has solved this problem. With this new protection method, deprotection can be achieved without the need for nucleophilic scavengers like aniline.

Summary: This study describes a mild protocol for amide formation using nitroarenes as nitrogen sources and an inexpensive iron complex as a catalyst. The method utilizes pH-neutral conditions and avoids the use of strong oxidants or reductants, allowing for tolerance of a wide range of aldehydes and nitroarenes with various functional groups.

Summary: In this study, a Ni-based N-modified TiO2-supported catalyst was designed for the selective conversion of CO2 to formic acid. The direct coordination between Ni and N was found to enhance the catalytic activity significantly, and nitrogen doping on the TiO2 surface was shown to lower the activation energy barrier. The stable performance of this catalyst makes it potentially important for practical applications.

Summary: In this study, a Ni-based N-modified TiO2-supported catalyst was designed for the direct CO2 hydrogenation to formic acid, exhibiting excellent activity, selectivity, and stability. Investigations on X-ray photoelectron spectroscopy and X-ray absorption spectroscopy confirmed the direct coordination between Ni and N, while DFT studies revealed the crucial effect of nitrogen doping on the TiO2 surface.

Summary: Ba-Ru/MgO catalysts are synthesized with an optimal Ru particle size and tailored BaO-Ru interfacial structures, which create a promoting effect through the separate storage of H+/e(-) pairs at the BaO-Ru interface. Chemisorbed H atoms on Ru dissociate into H+/e(-) pairs at the BaO-Ru interface, where selective capture of H(+) by strongly basic, nonreducible BaO leaves e(-) on Ru. The resulting electron accumulation in Ru facilitates N-2 activation and inhibits hydrogen poisoning during NH(3) synthesis.

Summary: Compared with the Haber Bosch process, the electrochemical nitrogen reduction reaction (NRR) offers a more environmentally friendly and sustainable route for ammonia synthesis. This study developed Co-doped Fe3S4 nanoflowers as a catalyst for NRR, achieving high Faradaic efficiency and NH3 yield rate. The introduction of Co atoms promoted N-2 absorption and accelerated the catalytic process, providing a pathway for enhancing ammonia synthesis using morphology and doping engineering for Fe-based electrocatalysts.
