Covalent organic nanosheets (CONs) have emerged as a new class of functional two-dimensional (2D) porous polymeric materials with high accessible surface, diverse functionality, and chemical stability. They could become versatile candidates for targeted drug delivery. Despite their many advantages, there are limitations to use target specific We anticipated that these drawbacks be overturned by judicious postsynthetic modification steps CONs The would not only produce the desired it also...
Abstract The copper(I)‐catalyzed cycloaddition reaction between azides and alkynes has been employed to make metal‐adhesive materials. Copper brass surfaces supply the necessary catalytic Cu ions, thus polymerization process occurs selectively on these metals in absence of added catalysts. Alternatively, copper compounds can be monomer mixtures then introduced reducing metal such as zinc initiate polymerization. resulting materials were found possess comparable or superior adhesive strength...
The experimental rate law for the Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction was found to vary in complex ways with concentration, presence of chloride ion, and accelerating ligands. Several examples discontinuous ("threshold behavior") kinetics were observed, along a decidedly nonlinear correlation electronic substituent parameter CuAAC p-substituted arylazides. previously observed tendency provide ditriazoles from conformationally constrained 1,3-diazide be affected by...

CdS nanoparticles were deposited on a highly stable, two-dimensional (2D) covalent organic framework (COF) matrix and the hybrid was tested for photocatalytic hydrogen production. The efficiency of CdS-COF investigated by varying COF content. On introduction just 1 wt% COF, dramatic tenfold increase in overall activity observed. Among various hybrids synthesized, that with 10 named (90:10), found to exhibit steep H2 production amounting 3678 μmol h(-1) g(-1), which is significantly higher...
Abstract A Gd III ‐based porous metal–organic framework (MOF), Gd‐pDBI, has been synthesized using fluorescent linker pDBI (pDBI=(1,4‐bis(5‐carboxy‐1H‐benzimidazole‐2‐yl)benzene)), resulting in a three‐dimensional interpenetrated structure with one‐dimensional open channel (1.9×1.2 nm) filled hydrogen‐bonded water assemblies. Gd‐pDBI exhibits high thermal stability, porosity, excellent along organic‐solvent and mild acid base stability retention of crystallinity. was transformed to the...

Water splitting, leading to hydrogen and oxygen in a process that mimics natural photosynthesis, is extremely important for devising sustainable solar energy conversion system. Development of earth-abundant, transition metal-based catalysts mimic the oxygen-evolving complex photosystem II, which involved oxidation water O2 during represents major challenge. Further, understanding exact mechanism, including elucidation role active metal-oxo intermediates (WO), critical development more...

Boronic acid-modified alginate allows the direct formation of biocompatible hydrogels under basic conditions with remarkable injectable, self-healing and multistimuli-responsive properties.
Hydrogels are hydrophilic three-dimensional networks with demonstrated potential for medical and pharmaceutical applications. Specifically, biopolymer-based hydrogels offer certain advantages over synthetic polymers in terms of biocompatibility biodegradability. Because their inherent properties, able to efficiently encapsulate liberate a controlled release manner, different hydrophobic therapeutic molecules, including nucleic acids, proteins antibodies.

We present first review development spread IBA concept since it was launched by BirdLife International (then ICBP) in 1979 examine some characteristics resulting inventory. Over 13,000 global regional IBAs have so far been documented terrestrial, freshwater marine ecosystems almost all world’s countries...
A unique proton conductive and moldable supramolecular metallogel (CuA-Ox gel) made upon mixing at room temperature well-defined stock solutions of Cu(OAc)2·H2O oxalic acid dihydrate was found to have self-healing properties. Remarkably, the system also displayed an unprecedented ability impart properties other gel networks lacking this capacity. self-healed CuA-Ox essentially same nanofibrillar morphology, thermal stability, rheological properties, conductivity as freshly prepared sample....
The emerging use of biohydrogels for the fabrication either conductive electrolytes or electrodes battery science and technology.
Solid-state organic electrochemical supercapacitors (OESCs) have been fabricated using poly(3,4-ethylenedioxythiophene) (PEDOT) electrodes, a biohydrogel as electrolyte system, and polyaniline fibers redox additive.
In this feature article, we discuss a series of contributions dealing with the in situ fabrication supramolecular metallogels (i.e. using low molecular weight ligands and metal ions) that show self-healing properties bulk gel phase after complete physical segregation. Most advances area have taken place during last three years are mainly represented by organogels, whereas examples hydrogels organic-aqueous gels still minority. gelation via metal-coordination compounds is conceptually...
Suturing peripheral nerve transections is the predominant therapeutic strategy for repair. However, use of sutures leads to scar tissue formation, hinders regeneration, and prevents functional recovery. Fibrin-based adhesives have been widely used reconstruction, but their limited adhesive mechanical strength inability promote regeneration hamper utility as a stand-alone intervention. To overcome these challenges, we engineered composite hydrogels that are neurosupportive possess strong...
