Abstract The solid electrolyte interphase (SEI) dictates the cycling stability of lithium‐metal batteries. Here, direct atomic imaging SEI's phase components and their spatial arrangement is achieved, using ultralow‐dosage cryogenic transmission electron microscopy. results show that, surprisingly, a lot deposited Li metal has amorphous structure, likely due to carbon oxygen impurities, that crystalline lithium carbonate not stable readily decomposes when contacting metal. Lithium...
Carbon dioxide (CO2) is an important C1 source for the generation of carboxylic acids and derivatives. Stoichiometric catalytic carboxylation nucleophiles, including organometallic reagents, with CO2 has been widely investigated. Since many kinds reagents are prepared from electrophiles, transition-metal-catalyzed direct diverse electrophiles attracted much attention high step economy user-friendly protocols. Although significant progress achieved, use stoichiometric metallic or pyrophoric...
We reported a one-step dry coating of amorphous SiO2 on spherical Ni-rich layered LiNi0.915Co0.075Al0.01O2 (NCA) cathode materials. Combined characterization XRD, EDS mapping, and TEM indicates that layer with an average thickness ∼50 nm was uniformly coated the surface NCA microspheres, without inducing any change phase structure morphology. Electrochemical tests show 0.2 wt% SiO2-coated material exhibits enhanced cyclability rate properties, combining better thermal stability compared...
The intriguing physics of vanadium dioxide (VO2) makes it not only a fascinating object study for fundamental research on solid-state but also an attractive means to actively modify the properties integrated devices. In particular, exceptionally large complex refractive index variation produced by insulator-to-metal transition this material opens up interesting opportunities dynamically tune optical systems. This Perspective reviews some exciting work done VO2 nanophotonics in last decade...
Abstract Lithium (Li) metal offers the highest projected energy density as a battery anode, however its extremely high reactivity induces dendrite growth and dead Li formation during repeated charge/discharge processes, resulting in both poor reversibility catastrophic failure. Approaches reported to date often seek suppress dendrites at expense of density. Here, strategy that resolves above conflict achieves dendrite‐free long‐term reversible anode is reported. A self‐organized core–shell...
Abstract Geminal ( gem −) disubstitution in heterocyclic monomers is an effective strategy to enhance polymer chemical recyclability by lowering their ceiling temperatures. However, the effects of specific substitution patterns on monomer's reactivity and resulting polymer's properties are largely unexplored. Here we show that, systematically installing ‐dimethyl groups onto ϵ‐caprolactam (monomer nylon 6) from α ϵ positions, both redesigned lactam ‐nylon 6’s highly sensitive position, with...
Cycloisomerization of 1,n-enynes and diynes is a powerful method in organic synthesis to access heterocyclic compounds has drawn increasing attention from chemists. In this paper, we attempted summarize our recent results on the transition metal-catalyzed cycloisomerization synthesize five or six-membered using having propargylic ester moiety. First, will describe 2,3-disubstituted 3-pyrrolines via gold catalyzed 1,6-diynes. addition, also disclose novel silver tandem 1,3-acyloxy...
Carbon dioxide, a nontoxic, cheap and readily available greenhouse gas, acts as the ideal carbonyl source with similar function combination of CO oxidants ('CO<sub>2</sub> = + O'). We highlight this concept recent advances lactamization lactonization C–H bond CO<sub>2</sub> under redox-neutral or even transition-metal-free conditions.
Abstract The bulk radical polymerization of bis(aziridine) with molten elemental sulfur resulted in brittle, cross‐linked polymers. However, when the was treated presence an organobase, ring‐opening reaction aziridine oligosulfide anions occurred, leading to formation linear polymers by step‐growth polymerization. These newly synthesized possess repeating units containing a sulfonamide or amide functional moiety and bonds average segment about two. A small molecular model confirmed...
Bis(indole) alkaloids analogues were prepared under mild conditions and in high yields through a gold-catalyzed cycloisomerization of 1,1-bis(indolyl)-5-alkynes (see scheme). The enantioselective version this reaction gave the corresponding products moderate to excellent (55–90 %), good ee values (48–96 satisfactory regioselectivities (3.5:1→20:1).
Aggregation-induced emission (AIE) active core cross-linked multiarm star polymers, carrying polystyrene (PS), polyethylene (PE), or polyethylene-b-polycaprolactone (PE-b-PCL) arms, have been synthesized through an "arm-first" strategy, by atom transfer radical copolymerization (ATRP) of a double styrene-functionalized tetraphenylethene (TPE-2St) used as cross-linker with linear arm precursors possessing terminal ATRP initiating moieties. Polyethylene macroinitiator (PE–Br) was prepared via...
Abstract Efficient cyclization of 1‐(indol‐3‐yl)‐3‐alkyn‐1‐ols in the presence a cationic gold(I) complex, leading to annulated or specific substituted carbazoles, was observed. Depending on reaction conditions and substitution pattern, divergent pathways were discovered, furnishing diversified carbazole structures. Cycloalkyl‐annulated [ b ]carbazoles are obtained through 1,2‐alkyl migration metal‐carbene intermediates; cycloalkyl‐annulated formed Wagner–Meerwein‐type shift; ethers...
