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)
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
Yahui Li, Dr. Kaiwu Dong, Fengxiang Zhu, Zechao Wang and Prof. Dr. Xiao-Feng Wu
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
Ho Yeung, Dr. Christopher J. Squire, Yuliana Yosaatmadja, Dr. Santosh Panjikar, Gemma López, Prof. Dr. Antonio Molina, Prof. Dr. Edward N. Baker, Dr. Paul W. R. Harris and Prof. Dr. Margaret A. Brimble
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
Kai Jiang, Dr. Ling Zhang, Junfeng Lu, Prof. Chunxiang Xu, Prof. Congzhong Cai and Prof. Hengwei Lin
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
Huibin Ge, Dr. Bin Zhang, Xiaomin Gu, Haojie Liang, Huimin Yang, Dr. Zhe Gao, Prof. Jianguo Wang and Prof. Yong Qin
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
Joshua P. Green, Dr. Yang Han, Rebecca Kilmurray, Prof. Martyn A. McLachlan, Prof. Thomas D. Anthopoulos and Prof. Martin Heeney
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.

Dr. Liumin Suo, Dr. Oleg Borodin, Wei Sun, Dr. Xiulin Fan, Dr. Chongyin Yang, Dr. Fei Wang, Tao Gao, Dr. Zhaohui Ma, Dr. Marshall Schroeder, Dr. Arthur von Cresce, Dr. Selena M. Russell, Prof. Michel Armand, Prof. Austen Angell, Dr. Kang Xu and Prof. Chunsheng Wang
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
Minghao Yu, Xinyu Cheng, Yinxiang Zeng, Zilong Wang, Prof. Yexiang Tong, Prof. Xihong Lu and Prof. Shihe Yang
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
Eva Reichhart, Dr. Alvaro Ingles-Prieto, Alexandra-Madelaine Tichy, Catherine McKenzie and Dr. Harald Janovjak
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.

Dr. Svetlana A. Chechetka, Dr. Eiji Yuba, Prof. Kenji Kono, Dr. Masako Yudasaka, Dr. Alberto Bianco and Dr. Eijiro Miyako
Nanorobots: Magnetic nanoparticle–carbon nanohorn–liposome supramolecular nanotransporters were developed. The remotely controlled release of functional molecules contained in the nanotransporters was achieved by applying a magnetic field and near-infrared laser light. The nanotransporters enabled enzymatic reactions at target sites in cells and mice.
