Intrinsic disorder refers to segments or whole proteins that fail self-fold into fixed 3D structure, with such sometimes existing in the native state. Here we report data on relationships among intrinsic disorder, sequence complexity as measured by Shannon's entropy, and amino acid composition. identified protein crystal structures, nuclear magnetic resonance, circular dichroism, prediction from sequence, all exhibit similar distributions are shifted lower values compared to, but...
Directed by increasing the density of coordination sites (DOCS) to increase stability assemblies, discrete 2D ring-in-rings and 3D sphere-in-sphere were designed self-assembled one tetratopic pyridyl-based ligand with 180° diplatinum(II) acceptors naked Pd(II), respectively. The high DOCS resulted multitopic provided more geometric constraints form structures stability. Compared reported supramolecular hexagons polyhedra ditotpic ligands, self-assembly such giant architectures using ligands...
In this study, we overcame a challenge in conventional self-assembly of macrocycles that uses ditopic 2,2':6',2″-terpyridine (tpy) building blocks with 120° angle between two ligating moieties, which generally produces mixture multiple instead single hexagon. Two supramolecular hexagon wreaths, [Zn9LA6] and [Zn12LB6], were designed self-assembled from tritopic tetratopic tpy ligands Zn(II) ions, respectively. These multitopic ligands, bearing binding sites, increased the total density...
Using a series of tritopic 2,2':6',2″-terpyridine (tpy) ligands constructed on adamantane, three discrete 3D metallo-supramolecular architectures were assembled, i.e., trigonal bipyramidal, tetrahedron, and cube. The self-assembly used as corner directing units metal ions glue at the edge. angles linkers between adamantane tpy head play critical role in guiding assembled structures, which have general formula M3nL2n, where M denotes ion L ligand. All complexes fully characterized by (1)H,...

Electrochemical reduction reaction of nitrate (NITRR) provides a sustainable route toward the green synthesis ammonia. Nevertheless, it remains challenging to achieve high-performance electrocatalysts for NITRR especially at low overpotentials. In this work, hierarchical nanospheres consisting polycrystalline Iridium&copper (Ir&Cu) and amorphous Cu2O (CuxIryOz NS) have been fabricated. The optimal species Cu0.86Ir0.14Oz delivers excellent catalytic performance with desirable NH3 yield rate...
Abstract Electrochemically promoted nitrate reduction reaction (NITRR) holds great potential for the “green” synthesis of ammonia (NH 3 ). However, NITRR in neutral media, though close to practical scenario, is often limited by an insufficient supply active hydrogen (*H) due sluggish water cleavage. In this work, it demonstrated that a bimetallic alloy FeIr can optimize trade‐off between and *H formation media. As result, exhibits excellent catalytic performance toward with Faradaic...
Preparing an autonomous self-healing supramolecular elastomer with sunlight degradability is still a challenging task in related fields. In this work, we report by using the classic host–guest complexation of visible-light-photolabile picolinium-containing adamantanes (Ad) and β-cyclodextrin nanogels (β-CD). The as-synthesized possesses merits high mechanical strength, excellent stretchability (>1500% strain), efficient (>85% at 60 min), ultrastability against electrolytes, photodegradation...
For a giant magnetostrictive rod under the action of multiple physical loads, such as an external magnetic field, temperature and axial pre-stress, this paper proposes general one-dimensional nonlinear magneto-thermo-mechanical coupled constitutive model. This model is based on Taylor expansion elastic Gibbs free energy material thermodynamic relations from perspective macro continuum mechanics. Predictions made using are in good agreement with experimental data for magnetization strain...
We utilize an in situ strategy to develop a highly efficient and durable electrocatalyst Ru&Cu/Cu 2 O towards nitrate reduction ammonia (e-NRA) alkaline media. The good e-NRA performance is attributed the synergy of Cu/Ru dual sites.
Abstract Poly(lactic acid) (PLA) and poly(lactic‐ co ‐GA) (PLGA) with low molecular weights were synthesized by a one‐step polycondensation of lactic acid (LA) glycolic (GA) molecules using stannous octoate as catalyst at 160°C. A high yield (>80%) all the polymers was obtained in study. The PLA PLGA copolymers characterized 1 H‐NMR, GPC, DSC measurements, etc. We elaborated HSA‐loaded microspheres based on different monomer ratios (LA/GA = 85:15, 75:25, 65:35, 50:50) solvent‐extraction...
Fullerene-based liquid crystalline materials have both the excellent optical and electrical properties of fullerene self-organization external-field-responsive crystals (LCs). Herein, we demonstrate a new family thermotropic [60]fullerene supramolecular LCs with hierarchical structures. The dyads undergo driven by π-π interactions to form triple-layer two-dimensional (2D) sandwiched between layers alkyl chains. lamellar packing 2D gives rise formation LCs. This design strategy should be...

These star-shaped patterns are also used both functional artistic man-made architectures. Here following a stepwise synthesis self-assembly approach, pentagonal hexagonal metallosupramolecules possessing motifs were prepared based on the careful design of metallo-organic ligands (MOLs). In MOL preparation, robust ruthenium–terpyridyl complexes employed to construct brominated...
Coordination-driven self-assembly as a bottom-up approach has witnessed rapid growth in building giant structures the past few decades. Challenges still remain, however, within construction of architectures terms high efficiency and complexity from simple blocks. Inspired by features DNA protein, which both have specific sequences, we herein design series linear blocks with sequences through coordination between terpyridine ligands Ru(II).

Herein, we report a light-driven, radical-type cyano migration in the absence of photocatalyst, enabling chemo-divergent synthesis (Z)-alkenyl nitriles and ketones. Trifluoromethyl thianthrenium salt (TT–CF3+OTf–) plays multiple roles: (a) absorbing light to generate trifluoromethyl radicals initiate reaction (b) forming α-thianthrenium species by situ capture TT• +. (Z)-Alkenyl were formed through elimination salts, aryl ketones obtained via nucleophilic substitution salts.
