Summary: In this study, a reticular chemistry approach was used to explore the application of a Zr(IV)-nanoMOF material in magnetic resonance imaging (MRI). By replacing Zr(IV) with Gd(III) and introducing water molecules, the material exhibited relaxation transfer in both the inner and outer spheres, leading to enhanced MRI performance. These findings demonstrate the potential of MOFs for T-1-weighted MRI through reticular chemistry.

Summary: This study presents a universal scheme for synthesizing core-shell hybrids (MOF@HOF) by using stable HOFs and surface-functionalized MOFs. The newly synthesized NH2-UiO-66@DAT-HOF core-shell nanostructure exhibits excellent stability and superb photocatalytic performance, with an apparent reaction rate constant up to 60.7 and 7.6 times higher than its parent materials NH2-UiO-66 and DAT-HOF for tetracycline degradation. This enhancement is attributed to the broader visible-light utilization range and efficient charge carrier separation supported by the S-scheme heterojunction. Furthermore, the photocatalytic efficiency of the core-shell nanostructure remains high after several-cycle applications.

Summary: In this study, In2O3@Ni2P (IO@NP) heterojunctions were successfully achieved by annealing MIL-68(In) and combining it with NP via a simple hydrothermal method. Visible-light photocatalysis experiments demonstrated that the optimized IO@NP heterojunction exhibited a dramatically improved H(2) release rate of 2485.5 μmol g(-1) h(-1), 92.4 times higher than that of IO. Optical characterization revealed that the doping of IO with an NP component promoted the rapid separation of photo-induced carriers and enabled the capture of visible light. Moreover, the interfacial effects of the IO@NP heterojunction and synergistic interaction between IO and NP provided plentiful active centers for reactants.

Summary: In this study, two isoreticular pillar-layer metal-organic frameworks, Co(aip)(bpy)0.5 and Co(aip)(pyz)0.5, were developed for the separation of C2H4/C2H6. The pore apertures of these frameworks are controlled by changing the length of the pillar ligands. Co(aip)(pyz)0.5, with a shorter pillar ligand, shows reduced pore size and molecular sieving separation of C2H4 from C2H6. Molecular simulation and dynamic breakthrough experiments confirm its high selectivity for C2H4.

Summary: The phase evolution of alloys and atomic diffusion are closely related. However, the influence of reactive diffusion on phase formation in high-entropy alloys (HEAs) is still not clear. This study investigates the phase evolution of a multicomponent CoCrFeNi/Al diffusion couple and reveals the combined effects of enthalpy and entropy on phase formation in HEAs at elevated temperatures. Surface modification of HEAs can be achieved through film deposition and annealing processes.

Summary: The orange carotenoid protein undergoes significant structural changes upon photoactivation, increasing the protein's motional freedom. This study used quasielastic neutron scattering to directly probe the protein dynamics of the orange carotenoid protein in the dark-adapted and active states, revealing enhanced internal dynamics upon photoactivation. The flexibility of the W288A mutant, assumed to mimic the active state structure, was found to be different, emphasizing the importance of in situ experiments.

Summary: In this study, CoCrFeMnNi high-entropy alloys with a surface gradient nanostructure were produced using industrial shot blasting, which significantly improved their mechanical properties. The severely plastically deformed surface layer had a multi-scale hierarchical structure and increased in depth with shot-blasting time. The microhardness and tensile strength of the alloy were significantly higher after shot-blasting. The improved strain hardening and prevention of early necking in the gradient-nanostructured surface layer contributed to its high toughness.

Summary: The effects of severe plastic deformation (SPD) by means of high-pressure torsion (HPT) on Fe73.9Cu1Nb3Si15.5B6.6 and Fe81.2Co4Si0.5B9.5P4Cu0.8 iron-based metallic glasses were compared. HPT processing extended the consolidation and deformation ranges for Fe73.9Cu1Nb3Si15.5B6.6, and achieved consolidation and deformation with minimum cracks for Fe81.2Co4Si0.5B9.5P4Cu0.8 for the first time. Various analyses revealed that Fe81.2Co4Si0.5B9.5P4Cu0.8 exhibited HPT-induced crystallization phenomena, while Fe73.9Cu1Nb3Si15.5B6.6 did not crystallize even at high HPT-deformation degrees.

Summary: Flexible metal-organic materials capable of stimulus-induced switching between closed and open structures show potential application in gas storage and separation. A clathrate coordination network is demonstrated to undergo gas-induced switching between multiple phases through transient porosity, allowing diffusion of guests between discrete voids. The material shows reversible switching between guest-free and gas-loaded phases, and the diffusion mechanism is elucidated using in situ X-ray diffraction and computational methods.

Summary: In this study, TiAl and Cr3C2 particles were added to a CrMnFeCoNi alloy to improve its processibility and mechanical properties. The addition of TiAl particles resulted in the formation of cracks, but the further addition of Cr3C2 particles helped suppress hot cracking. The presence of long-range ordered domains and precipitates contributed to the improved strength of the dual-particle containing alloy.

Summary: The design and synthesis of a new type of zeolite-like metal-organic frameworks (ZMOFs) with intrinsic structural features is highly desirable but challenging. In this study, two rare-earth (RE)-MOFs, Tb-ZMOF-2 and Tb-ZMOF-3, were successfully obtained through solvothermal reactions. Structural analyses revealed the novel [4(4)6(4)8(2)] cage in Tb-ZMOF-2 and the simultaneous presence of nonanuclear (D6R) and hexanuclear (D4R) RE clusters in Tb-ZMOF-3, resulting in two new zeolitic topologies. Tb-ZMOF-2 demonstrated high gravimetric and volumetric methane storage working capacities due to its high surface area and pore volume.

Summary: This study focuses on the synthesis and properties comparison of a novel organic composite nanofiber material consisting of styrene-butadiene-styrene (SBS) copolymer blended with polystyrene (PStyr) and carbon nanotubes (CNTs). The addition of CNTs retards the crystallization process and decreases the absorbance of both SBS/PStyr and PStyr/PBu in Fourier transform infrared spectroscopy. The interaction of CNTs with the blend is limited in samples with SBS, as observed in Raman spectroscopy.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

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.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
