Summary: Robust soil organic matter (SOM) mapping is necessary for farms; however, it is cost prohibitive to chemically analyze a large number of samples. Recent research has shown that visible and near-infrared (vis-NIR) reflectance spectroscopy can accurately estimate SOM in a cost-effective manner. This study aimed to compare the mapping accuracy with and without the use of vis-NIR spectroscopy as a covariate. Results indicated that adding vis-NIR spectra as covariates significantly improved the map accuracy, providing a cost-efficient technique for fine-resolution spatial mapping of soil information.

Summary: In this study, Au-CuxOy hybrid nanoparticle-encapsulated hollow porous silica nanospheres (Au-CuxOy in HPSNs) were synthesized by immobilizing the catalytic functionality inside hollow cavities using polyethyleneimine in a reverse microemulsion system. Compared to individual Au and CuxOy, the prepared Au-CuxOy in HPSNs showed significantly improved catalytic efficiency for the reduction of various nitrophenols with NaBH4. The enhanced performance can be attributed to the synergistic effect between Au and CuxOy, as well as the protection provided by the silica shells for the inner Au-CuxOy.

Summary: Protein crystallization is a remarkable natural phenomenon, although the formation of a nucleus in this process is still poorly understood. The two-step nucleation model has emerged as a consensus, but further experimental verification is needed. By studying the nucleation pathway of glucose isomerase, it was found that nanoscopic crystallites with lattice symmetry equivalent to mature crystals are present in the early stages of the reaction process, highlighting the importance of experimental data for a general understanding of protein crystal nucleation.

Summary: Here, we present the redox reactivity of a multimetallic uranium complex supported by triphenylsiloxide ligands, demonstrating the stabilization of low valent synthons through intramolecular ligand migration. The reduction of the diuranium(IV) complex yields U-II/U-IV and U-I/U-IV complexes via ligand migration and formation of uranium-arene delta-bond interactions. Additionally, the reductive coupling of pyridine is achieved through ligand migration, restoring the original ligand arrangement. This work provides a new method for controlling the redox reactivity of unstable, low-valent metal complexes and can contribute to the development of f-elements redox reactivity.

Summary: The biological reduction of soluble U(VI) complexes to form immobile U(IV) species is a potential method for remediating contaminated sites. Multiheme c-type cytochromes (MHCs) have been identified as key mediators of electron transfer to aqueous phase U(VI) complexes in bacteria such as Shewanella oneidensis MR-1. Recent studies have revealed the role of MHCs in the reduction process and the stabilization of U(V)-dpaea species in aqueous solution. This research aims to clarify the involvement of MHCs and determine the mechanism of solid phase U(VI)-dpaea reduction.

Summary: Rigidtritopic linkers were utilized to build porous U-(IV) and Th-(IV) 3D frameworks with tunable charge. Multiple coordination polymers based on U-(IV) and Th-(IV) were synthesized using different trianionic carboxylates as ligands. The structure and dimensionality of the final actinide assembly were influenced by the ligand architecture, pH, stoichiometry, metal nature, and concentration. The synthesized coordination polymers exhibited high surface areas. A crystal-to-crystal transformation from a cationic to a neutral framework was observed during postsynthetic solvent substitution. Rating: 8/10.

Summary: Nonpyrophoric amines phosphines react with indium(III) halides in the presence of zinc chloride to synthesize colloidal indium phosphide (InP) quantum dots. However, the required P/In ratio of 4:1 makes it challenging to prepare large-sized and near-infrared absorbing/emitting InP QDs using this method. To overcome this, a synthetic approach using indium(I) halide as both the indium source and reducing agent for aminophosphine is introduced. This zinc-free method produces tetrahedral InP QDs with an edge length >10 nm and narrow size distribution.

Summary: Liquid-liquid phase separation is a crucial mechanism for the dynamic compartmentalization of macromolecules in response to physicochemical factors. In the model plant Arabidopsis thaliana, the protein ELF3 drives temperature-sensitive growth by undergoing liquid-liquid phase separation. Through a combination of biochemical, biophysical, and structural techniques, this study investigates the behavior of the ELF3 protein with varying lengths of its poly-glutamine tract. The results show that the dilute phase of ELF3 forms a monodisperse higher-order oligomer, which undergoes pH- and temperature-sensitive phase separation, leading to the formation of a hydrogel.

Summary: Significant advances have been made in the chemistry of actinide-nitrides, particularly with uranium and some breakthroughs with thorium. Synthetic routes to uranium nitrides have been identified, but ligands capable of stabilizing them are still limited. Terminal- and bridging-nitrides are attractive for potential reactivity, especially in the field of uranium complexes for dinitrogen reduction and functionalization. Molecular thorium bridged-nitride complexes have recently been discovered, suggesting the possibility of expanding nitride chemistry to low-valent thorium and transuranic elements.

Summary: Understanding the importance of multimetallic cooperativity and alkali ion-binding in the second coordination sphere is crucial for the design of complexes that can facilitate the cleavage and functionalization of dinitrogen (N-2) molecules. In this study, the reaction products and mechanism of N-2 reduction were compared for different uranium(III) complexes with and without alkali ion binding. It was found that the removal of alkali ions enhanced the reducing ability of the complex and led to the formation of new species. Furthermore, the formation of a tetranuclear uranium-N-2 intermediate was proposed, demonstrating the possibility of a three-electron transfer from U(III) to N-2.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
