Summary: Small heat-shock proteins (sHSPs) play important roles in the cellular stress response across all species, primarily by binding early unfolding states of proteins to prevent aggregation. Research on yeast Hsp26 using cross-linking mass spectrometry (XL-MS) has provided detailed structural information on sHSP activation and client binding, revealing the significance of the middle domain in client-independent interaction and potential client specificity through additional binding sites within its alpha-crystallin domain and C-terminal extension.

Summary: This study focuses on the thermal activation of surface-attached polymer networks under mild conditions, using a novel cross-linker based on a diazo phenyl ester group. The system, which enables the rapid complete cross-linking of films with simultaneous surface attachment to organic materials via CHic, only requires activation below 100 degrees C and has a long shelf life at room temperature. It has potential applications in coatings and complex geometries.

Summary: This article presents a designed synthesis method to adjust the flexibility of two-dimensional COFs, which includes the preparation of rigid COF (R-COF), semi-flexible COF (SF-COF), and flexible COF (F-COF) through polymerization, linker exchange, and linkage conversion. The study reveals significant differences in breathing behavior and self-adaptive capability among the three COFs through vapor response and iodine capture experiments. Gas sorption experiments show that the porosity of F-COF can switch from a close state in nitrogen to an open state in carbon dioxide, which is not observed for R-COF and SF-COF. This research provides insights into the impact of different flexibility on properties of COFs and offers a strategy to adjust their flexibility by tuning their linkers and linkages.

Summary: A sulfonated poly(ethersulfone) (SPES)-metal-organic framework (MOF) film with excellent proton conductivity was synthesized by anchoring UiO-66-NH2 to the main chain of the aromatic polymer through the Hinsberg reaction. The chemical bond formed between the amino group in MOFs and the -SO2Cl group in chlorosulfonated poly(ethersulfones) enabled the membrane to have excellent proton conductivity. Experimental and simulated results confirmed the successful synthesis of UiO-66-NH2 using powder X-ray diffraction patterns. Fourier transform infrared spectra also confirmed the successful preparation of SPES, PES-SO2Cl, and a composite film.

Summary: This study investigates the structural changes of a square lattice coordination network under high pressure. The results show that the interlayer separation of the network does not increase under high pressure, but the crystals are compressed and the adsorbed molecules are released. The changes induced by pressure are discussed in terms of structural voids, framework conformation, and molecular packing. Additionally, analysis of the electron count in the pores confirms the multistep evacuation of the adsorbed molecules and suggests the existence of intermediate phases.

Summary: In this study, a new two-dimensional square lattice coordination network, sql-(azpy)(pdia)-Ni, was reported to exhibit guest-induced switching between closed and open phases. The structural transformations were enabled by the presence of a pendant phenyldiazenyl moiety on the pdia2- ligand. Various guests were accommodated through parallel slippage of layers and interlayer expansion. The network also exhibited elastic-like properties induced by adaptive guest binding.

Summary: As the freshwater crisis looms, metal-organic frameworks (MOFs) with stepped isotherms are at the forefront of desiccant development for atmospheric water harvesting (AWH). Diffusion to the sorbent bed surface limits the AWH kinetics of seven known MOFs and the industry-standard desiccant Syloid. A quantitative model exploiting isotherm shape reveals that steady-state oscillation optimizes productivity and dense ultramicroporous MOFs with a step at low relative humidity offer superior volumetric performance.

Summary: An emerging strategy in gas storage technology is the development of physisorbents that undergo transformations in response to stimuli. This study reports two isostructural light modulated adsorbents (LMAs) that transform from non-porous to porous upon adsorption. LMA-1 exhibited multi-step adsorption while LMA-2 showed a single-step adsorption isotherm. The light responsive nature of the ligand was exploited with LMA-1 showing a maximum reduction of CO2 uptake under irradiation.

Summary: Gas or vapor-induced phase transformations in flexible coordination networks (CNs) have the potential to outperform their rigid counterparts for separation and storage applications. Ligand modification has been used to alter the properties of these materials, but they have received less attention compared to rigid CNs. In this study, a family of Zn2+ CNs with variable flexibility was investigated, and it was found that the substituent moieties attached to a linker influenced both the structure and gas sorption properties of the networks. Some networks exhibited reversible transformation from small pore to large pore phases. The insights from this study can be applied to other classes of CNs.

Summary: Compared to rigid physisorbents, switching coordination networks offer promise for gas/vapour storage and separation due to their improved working capacity and thermal management properties. X-dmp-1-Co, a coordination network exhibiting switching enabled by transient porosity, is the parent member of a family of transiently porous coordination networks [X-dmp-1-M] (M = Co, Zn, and Cd). Each member exhibits different threshold pressures for CO2, H2O, and CH4, with tuning attributed to differences and changes in metal coordination spheres and ligand rotation.

Summary: In this study, a new N-donor carboxylate linker, β-(3,4-pyridinedicarboximido)propionate (PyImPr), was used to synthesize Cd(PyImPr)(2)via two different methods, resulting in 2D or 3D supramolecular isomers. Crystal structure analysis revealed that both isomers consist of the same carboxylate bridged rod building block (RBB), and the ethylene moiety of PyImPr enabled structural flexibility. Furthermore, analysis of the Cambridge Structural Database (CSD) provided insights into the relative frequency of RBB topologies in related ML2 coordination networks.

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.
