Stable Aqueous Photoelectrochemical CO2 Reduction by a Cu2O Dark Cathode with Improved Selectivity for Carbonaceous Products

Stable Aqueous Photoelectrochemical CO2 Reduction by a Cu2O Dark Cathode with Improved Selectivity for Carbonaceous Products

Copper on the dark side: Cu2O preferentially reduced CO2 to fuels while suppressing hydrogen evolution. It was found that the photogenerated holes primarily account for the instability of Cu2O. The Cu2O was used as a dark cathode to minimize the adverse effects of holes, achieving excellent stability and a selectivity of 92.6 % for carbonaceous products in CO2 photoreduction.

Chemical-Bonding-Directed Hierarchical Assembly of Nanoribbon-Shaped Nanocomposites of Gold Nanorods and Poly(3-hexylthiophene)

Chemical-Bonding-Directed Hierarchical Assembly of Nanoribbon-Shaped Nanocomposites of Gold Nanorods and Poly(3-hexylthiophene)

Turning fibers into ribbons: Nanoribbon-shaped nanocomposites composed of a conjugated polymer, poly(3-hexylthiophene) (P3HT), and plasmonic gold nanorods (AuNRs) are produced by a co-assembly of thiol-terminated P3HT nanofibers with dodecanethiol-coated AuNRs. Owing to plasmon coupling between adjacent aligned AuNRs these nanocomposites show broadened and red-shifted absorption bands.

Copper-Catalyzed Carbonylative Coupling of Cycloalkanes and Amides

A copper-catalyzed carbonylative synthesis of imides starting from cycloalkanes and amides has been developed. The imides were prepared in good yields by carbonylation of a C(sp3)−H bond of the cycloalkane with the amides acting as weak nucleophiles (DTBP=di-tert-butylperoxide, 1,10-phen=1,2-phenanthroline hydrate).

Radiation Damage and Racemic Protein Crystallography Reveal the Unique Structure of the GASA/Snakin Protein Superfamily

Ripping into quasi-racemic crystals: The structure of the 63-residue antimicrobial protein snakin-1, the first structure of the GASA/snakin superfamily, has been determined using total chemical synthesis, racemic protein X-ray crystallography, and radiation-damage-induced phasing. The protein adopts a unique fold containing six disulfide crosslinks and presenting a distinct electrostatic surface.

Triple-Mode Emission of Carbon Dots: Applications for Advanced Anti-Counterfeiting

Show me the money! A composite comprising carbon dots exhibits three kinds of emission simultaneously: photoluminescence (PL), up-conversion PL (UCPL), and room temperature phosphorescence (RTP). This unique feature could be applied to combat counterfeiting in the form of a printable ink with three modes of optical authentication.

A Tandem Catalyst with Multiple Metal-Oxide Interfaces Produced by Atomic Layer Deposition

A tandem catalyst based on Ni/Al2O3 and Pt/TiO2 with multiple metal-oxide interfaces showed high efficiency in the hydrogenation of nitrobenzene using N2H4⋅H2O as hydrogen source. The synergy of the Ni/Al2O3 and Pt/TiO2 interfaces in a confined nanospace led to the observed activity enhancement. The confined nanospace favored the instant transfer of intermediates between the two metal-oxide interfaces.

An Air-Stable Semiconducting Polymer Containing Dithieno[3,2-b:2′,3′-d]arsole

Arsenic-containing conjugated polymers were obtained by copolymerization of the first dithieno[3,2-b;2′,3′-d]arsole derivative. These polymers are stable under ambient conditions in their +3 oxidation state and display p-type semiconductivity with promising hole mobility in field-effect transistors.

Advanced High-Voltage Aqueous Lithium-Ion Battery Enabled by “Water-in-Bisalt” Electrolyte

Ready salted: A new class of electrolyte a “water-in-bisalt” electrolyte, that is, an electrolyte made from two salts, has a wider electrochemical stability window for aqueous lithium-ion batteries. The unprecedented high ionic density in the solution effectively suppresses hydrogen evolution and promotes the formation of a more protective solid electrolyte interphase (SEI).

Dual-Doped Molybdenum Trioxide Nanowires: A Bifunctional Anode for Fiber-Shaped Asymmetric Supercapacitors and Microbial Fuel Cells

High-performance fiber-shaped electrodes: A strategy for dual doping with nitrogen and low-valent molybdenum atoms was used to improve the electrochemical properties of MoO3. The dual-doped MoO3 nanowires showed exceptional device performances as bifunctional anode material for both fiber-shaped asymmetric supercapacitors (ASCs) and microbial fuel cells (MFCs).

A Phytochrome Sensory Domain Permits Receptor Activation by Red Light

Go deep with red: The sensory domain (S) of the cyanobacterial phytochrome 1 (CPH1) was repurposed to induce the homodimerization of proteins in living cells by red light. By using this domain, light-activated protein kinases were engineered that can be activated orthogonally from many fluorescent proteins and through mammalian tissue. Pr/Pfr=red-/far-red-absorbing state of CPH1.
