Summary: Poly(3,4-ethylenedioxythiophene) (PEDOT), a conducting polymer, is used to coat metal neural electrodes for improved performance. However, PEDOT-coated electrodes often suffer from mechanical instability. This study systematically evaluates the electropolymerization and surface morphology of PEDOT:PSS, optimizing the deposition for recording neural electrodes. The modified electrodes demonstrate good electrochemical performance without triggering redox reactions.

Summary: In this study, gold (Au) films were deposited onto vertically aligned carbon nanotubes (CNTs) using the DC magnetron sputtering method to create supercapacitor electrodes. The resulting Au@CNTs had a porous nanostructure morphology with a high apparent surface area. The porous Au/CNTs electrodes showed a good areal capacitance compared to traditional Au-based electrodes (25.6 mF cm-2 at 5 mV/s) and excellent cycling stability (90% retention after 10,000 cycles) in a 0.5 M H2SO4 aqueous solution. This research demonstrates the advantageous use of CNTs in fabricating porous Au deposits for improved electrochemical energy storage. Furthermore, these porous structures can serve as templates for other materials in electrochemical energy storage.

Summary: This paper introduces contorted hexabenzocoronene (c-HBC) derivatives as a potential universal precursor for synthesis of carbon materials with dimensions ranging from 1-D to 3-D. By controlling the assembly dimensions and intermolecular interactions of c-HBC derivatives, carbon products with different dimensions and high crystallinity can be synthesized. The use of copper vapor allows further control of crystallinity, and the carbonization process of c-HBC enables the growth of graphene-like structures on arbitrary substrates.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. 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.
