Hydrogel electrodeposition based on bipolar electrochemistry
Bipolar electrochemistry has attracted great interest for applications based on sensing, electrografting, and electrodeposition, because the technique enables electrochemical reactions to be induced at multiple bipolar electrodes (BPEs) with only a single power supply. However, there are only a few ...

Glutathione-responsive homodithiacalix[4]arene-based nanoparticles for selective intracellular drug delivery
Glutathione-responsive, paclitaxel-loaded nanoparticles based on homodithiacalix[4]arene were successfully developed, exhibiting selective drug release in cancer cells....

A simple and versatile strategy for realizing bright multicolor mechanoluminescence
Multicolor mechanoluminescence(ML) is first realized by using the stable organic blue ML emitter N-henylcarbazole as host matrix. It is claimed that a good ML host should have a moderate melting point and can dissolve or disperse organic dyes but maintain high ML activity and crystallinity. This str...

Chemical separation and MC-ICPMS analysis of U, Th, Pa and Ra isotope ratios of carbonates
Diagenetic alteration of fossil reef corals may have severe effects on the reliability of 230Th/U-ages. The widely applied criteria introduced to test for the reliability of coral 230Th/U-ages are often not sufficient to identify all altered ages. The combination of 230Th/U- with 231Pa/U-dating has ...

Nitrogen enriched polytriazine as metal-free heterogeneous catalyst for the Knoevenagel reaction in mild condition
Nitrogen enriched (52 wt %) nanoporous polytriazine with high specific surface area up to 850 m2 g-1 is synthesized by an ultrafast (30 min reaction time) microwave assisted route using inexpensive precursors cyanuric chloride and melamine at 400 W. The metal-free highly electron rich material is us...

Drastic rearrangement of self-assembled hydrogen-bonded tapes in a molecular crystal
A 2 : 1 hydrogen-bonded crystal of 2-pyrrolidone and chloranilic acid shows structural phase transitions accompanied by the drastic rearrangement of hydrogen-bonded tapes. Such a phenomenon is attributed to the selective and directional character of hydrogen bonds....

Production of Dynamic Lipid Bilayers Using the Reversible Thiol-Thioester Exchange Reaction
Thiol lysolipids undergo thiol-thioester exchange with two phenyl thioester-functionalized tails to produce phospholipid structures that assemble into liposomes with differences in exchange rates, temperature sensitivity, permeability, and continued exchange behavior. This in situ formation reaction...

Synthesis of Poly(L-lactide)/[small beta]-cyclodextrin/citrate Networks Modified Hydroxyapatite and its Biomedical Properties
Hydroxyapatite (HA) was modified by chelation of citric acid and Ca on the surface of HA, followed by the cross-linking between the hydroxyl groups of β-cyclodextrin (β-CD) and citrate, and then further in situ ring-opening polymerization of L-lactide over the hydroxyl groups. The modification of HA...

Recent advances in the annulation of Morita–Baylis–Hillman adducts
In this review, we summarize some of the most recent advances in the construction of cyclic compounds from the annulation of Morita–Baylis–Hillman (MBH) adducts, which have demonstrated their importance by possessing diverse functional groups. Significant examples including [3 + 2], [3 + 3], [3 + 4]...

Measuring the size and complex refractive index of an aqueous aerosol particle using electromagnetic heating and cavity-enhanced Raman scattering
A quantitative understanding of light scattering by small homogeneous particles requires accurate knowledge of particle geometry and complex refractive index, m = n + ik. In weakly absorbing particles, k can be on the order of 10−9, which is well below the detection limit of almost all light scatter...

4,4[prime or minute],4[prime or minute][prime or minute]-Triaminotriphenylamine-based porous polyimide as a visible-light-driven photocatalyst
Aiming to develop a visible-light-driven polymeric photocatalyst that can be fabricated by an easy-to-scale-up polymerization method, a porous polyimide (PPI) with a specific surface area (SBET) of 79.3 m2 g−1 was synthesized by a facile polycondensation of 3,3′,4,4′-benzophenonetetracarboxylic dian...

A dual pH-responsive supramolecular gelator with aggregation-induced emission properties
Functionalising AIE-active aromatic thioethers with self-complementary zwitterionic binding sites leads to a dual pH-responsive supramolecular organogelator with aggregation-induced emission (AIE) properties. The self-assembled fibrillar gel network is highly fluorescent (λem = 490 nm), whereas the ...

Asymmetric Organocatalytic Synthesis of Chiral 3,3-Disubstituted Oxindoles via 1,6-Conjugate Addition Reaction
A highly efficient synthesis of chiral 3,3-disubstituted oxindoles was developed by using a chiral spirocyclic phosphoric acid catalyzed 1,6-conjugate addition reaction of para-quinone methoids derived from N-unprotected isatins with indoles. The reaction proceeds under mild reaction conditions to p...

Dynamical resonances in chemical reactions
The transition state is a key concept in the field of chemistry and is important in the study of chemical kinetics and reaction dynamics. Chemical reactions in the gas phase are essentially molecular scattering processes, which are quantum mechanical in nature. Thus probing and understanding detaile...

Anodic dissolution growth of metal–organic framework HKUST-1 monitored via in situ electrochemical atomic force microscopy
In situ electrochemical atomic force microscopy (ec-AFM) is utilised for the first time to probe the initial stages of metal–organic framework (MOF) coating growth via anodic dissolution. Using the example of the Cu MOF HKUST-1, real time surface analysis is obtained that supports and verifies many ...
