The article presents a study which examines the highly reversible lithium (Li)/dissolved polysulfide cell using a free-standing and self-weaving multi-walled carbon nanotube (MWCNT) paper as an electrode. The study investigates the MWCNT paper by a chemical vapor deposition process. The study reveals that a highly reversible Li/dissolved polysulfide cells were demonstrated as a host electrode.

Light to wear: Aluminum coated fibrous materials with excellent electrical conductivity and mechanical endurance are fabricated at room temperature by a chemical solution process. The resulting aluminum‐coated conductive papers and threads can be used in electric circuits for flexible and wearable electronics. [ABSTRACT FROM AUTHOR]

Making sense: A novel polyacetylene composite material with incorporated aligned carbon nanotubes shows rapid changes in both fluorescent intensity and color appearance in response to applied electric currents, and these electrochromatic transitions remain reversible even after a thousand cycles. The composite material is anticipated to be suitable for various other sensing applications. [ABSTRACT FROM AUTHOR]

Wearable electronics require highly conductive fibrous materials, which can now be fabricated at room temperature. In their Communication on page 7718 ff., H. M. Lee, S. H. Ko, and co‐workers demonstrate that cotton or paper fibers can be impregnated and coated with Al atoms from the precursor Al{O(C4H9)2}. The fibrous materials exhibit excellent electrical conductivity, as well as enduring mechanical strength, which is indicative of their potential applications for flexible and wearable electronics.

This paper discloses the first uses of phosphahelicenes as chiral ligands in transition-metal catalysis. Unlike all known helical phosphines used so far in catalysis, the phosphorus function of phosphahelicenes is embedded in the helical structure itself. This crucial structural feature originates unprecedented catalytic behaviors and efficiency. An appropriate design and fine tuning allowed both high catalytic activity and good enantiomeric excesses to be attained in the gold promoted cycloisomerizations of N-tethered 1,6-enynes and dien-ynes.

This paper compares rates of charge transport by tunneling across junctions with the structures AgTSX(CH2)2 nCH3 //Ga2O3 /EGaIn ( n=1-8 and X= SCH2 and O2C); here AgTS is template-stripped silver, and EGaIn is the eutectic alloy of gallium and indium. Its objective was to compare the tunneling decay coefficient ( β, Å−1) and the injection current ( J0, A cm−2) of the junctions comprising SAMs of n-alkanethiolates and n-alkanoates. Replacing AgTSSCH2-R with AgTSO2C-R (R=alkyl chains) had no significant influence on J0 (ca. 3×103 A cm−2) or β (0.75-0.79 Å−1)-an indication that such changes (both structural and electronic) in the AgTSXR interface do not influence the rate of charge transport. A comparison of junctions comprising oligo(phenylene)carboxylates and n-alkanoates showed, as expected, that β for aliphatic (0.79 Å−1) and aromatic (0.60 Å−1) SAMs differed significantly.

This paper describes the hydrofluorination of alkenes through sequential H− and F+ addition under palladium catalysis. The reaction is cis specific, thus providing access to benzylic fluorides. The mechanism of this reaction involves an ionic pathway and is distinct from known hydrofluorinations involving radical intermediates. The first catalytic enantioselective hydrofluorination is also disclosed. [ABSTRACT FROM AUTHOR]

A straightforward photo-annealing approach was developed for building functional polymer layers on paper. Conducting polyaniline with the ability for photothermal conversion can be readily annealed by near-infrared light. The annealed polymers become both insulating and hydrophobic. Selective photo-annealing produces a functional layer with patterned conductive arrays. This material exhibits real-time response to ammonium gas. Complete photo-annealing preserves the porous structure but changes the wettability of the polyaniline-nanofiber film. [ABSTRACT FROM AUTHOR]

A photo‐annealing approach was developed for building functional polymer layers on paper. In their Communication on page 4465 ff., Y. Wang and co‐workers show that conducting polyaniline with the ability to undergo photothermal conversion can be annealed by near‐infrared light. The porous structure is retained in the annealed polymer but it becomes insulating and hydrophobic. The asymmetric paper functions as a “water diode” and selective photo‐annealing produces patterned conductive arrays. [ABSTRACT FROM AUTHOR]
