The sluggish lithium-ion transport kinetics in anode materials triggers a huge voltage polarization and serious lithium metal plating, greatly restricting the cycling life and energy density of the fast-charging lithium-ion batteries. Here we propose a new idea of self-expanding lithium-ion transport channels to construct a fast-charging anode and realize high-performance fast-charging lithium-ion

Synthetic innovation to construct sophisticated nanographenes is of fundamental significance for a variety of advanced applications. Herein, we report a distinctive method to prepare π -extended chiral nanographenes with 29 benzenoid rings and two helical breaches from a highly crowded perylene-cored oligoarylene precursor. Under Scholl’s condition, the reaction majorly involves the regioselective

We present the first nitridic analogs of micas, namely AE Si 3 P 4 N 10 (NH) 2 ( AE = Mg, Mg 0.94 Ca 0.06 , Ca, Sr), which were synthesized under high-pressure high-temperature conditions at 1400 °C and 8 GPa from the refractory nitrides P 3 N 5 and Si 3 N 4 , the respective alkaline earth amides, implementing NH 4 F as a mineralizer. The crystal structure was elucidated by single-crystal diffraction

Microbial secondary metabolite discovery is often conducted in pure monocultures. In a natural setting, however, where metabolites are constantly exchanged, biosynthetic precursors are likely provided by symbionts or hosts. In the current work, we report eight novel and architecturally unusual secondary metabolites synthesized by the bacterial symbiont Phaeobacter inhibens from precursors that, in

Many technologically relevant transition metal oxides for advanced energy storage and catalysis feature reduced transition metal (TM) oxides and are often nontrivial to prepare because of the need to control the reducing nature of the atmosphere in which they are synthesized. In this work, we show that an ab initio predictive synthesis strategy can be used to produce multiple gram-scale products of

The direct ring-opening polymerization (ROP) of propylene carbonate (PC) only affords oligomers with substantial unidentified by-products, which hinders the efficient utilization of PC. Through detailed studies, for the first time, a careful mechanism involving the in situ release of propylene oxide (PO) from PC decarboxylation is proposed. Further, we report a novel strategy of copolymerization of

Bottom-up synthetic biology is the science of building systems that mimic the structure and function of living cells from scratch. To do this, researchers combine tools from chemistry, materials science and biochemistry to develop functional and structural building blocks to construct synthetic cell-like systems. The many strategies and materials that have been developed in recent decades have enabled

While of interest, synthetically feasible access to boryl ligands and complexes remains limited, meaning such complexes remain underexploited in catalysis. For bidentate boryl ligands, oxidative addition of boranes to low valent Ir(I) or Pt(0) are the only examples yet reported. As part of our interest in developing improved group 10 ethylene polymerization catalysts, we present here an optimized synthesis

A fluxional bis-monodentate ligand, based on the archetypal shape-shifting molecule bullvalene, self-assembles with M2+ (M = Pd2+ or Pt2+) to produce a highly complex ensemble of permanently fluxional coordination cages. Metal-mediated self-assembly selects for an M2L4 architecture while maintaining shape-shifting ligand complexity. A second level of simplification is achieved with guest-exchange;

Polydimethylsiloxane (PDMS) as the benchmarked organophilic membrane remain challenges for removal of aromatic compounds due to the undesirable transport channels. In this work, we propose to reconstruct the PDMS conformation with tunable side group mobility by introducing phenyl as rigid molecular spacer to relieve steric hindrance of large-sized aromatic molecules; meanwhile, polymer segments are

Precise delivery of a proton plays a key role in O 2 activation at iron oxygenases, enabling the crucial O-O cleavage step that generates the oxidizing high valent metal-oxo species. Such proton is delivered by acidic residues that may either directly bind the iron center or lie in its second coordination sphere. Herein, a supramolecular strategy for enzyme-like H 2 O 2 activation at a biologically

Polymer gels, such as hydrogels, consisting of cross-linked polymer chains and small molecule solvents, have been widely used in biomedical applications, flexible electronics and soft machines due to the similarity of their mechanical properties to those of soft biological tissues. Polymer network design and its contribution to the properties of such materials has been extensively studied. In this

Cancer nanomedicine combined with immunotherapy has become a promising strategy for treating cancer in terms of safety and potency; however, precise regulation of the activation of antitumor immunity remains challenging. We herein report a smart semiconducting polymer nano-immunomodulator (SPNI) in response to acidic tumor microenvironment (TME) for precision photodynamic immunotherapy of cancer. SPNI

With the highest energy density ever among all sorts of commercialized rechargeable batteries, Li-ion batteries (LIBs) have stimulated the upsurge utilization in 3C devices, electric vehicles, and stationary energy storage systems. However, a high performance of commercial LIBs based on ethylene carbonate electrolytes and graphite anodes can only be achieved at above -20°C, which restricts their applications

The Josephson effect results from the coupling of two superconductors across a spacer such as an insulator, a normal metal or a ferromagnet to yield a phase coherent quantum state. However, in junctions with ferromagnetic spacers, very long-range Josephson effects have remained elusive. Here we demonstrate extremely long-range (micrometric) high-temperature (tens of kelvins) Josephson coupling across

We utilize the solvent acidolysis crystallization technique to grow mixed dimethylammonium/methylammonium lead tribromide (DMA/MAPbBr3) crystals reaching the highest dimethylammonium incorporation of 44% while maintaining the 3D cubic perovskite phase. These mixed perovskite crystals show suppression of the orthorhombic phase and a lower tetragonal to cubic phase transition temperature compared to

Materials with strong magneto-structural coupling have complex energy landscapes featuring multiple local ground states, thus making it possible to switch among distinct magnetic-electronic properties. However, these energy minima are rarely accessible by a mere application of an external stimuli to the system in equilibrium state. Here, we report that a ferromagnetic ground state, with Tc above room

Engineered living materials could have the capacity to self-repair and self-replicate, sense local and distant disturbances in their environment, and respond with functionalities for reporting, actuation or remediation. However, few engineered living materials are capable of both responsivity and use in macroscopic structures. Here we describe the development, characterization and engineering of a

Owing to outstanding electrical/electrochemical performance, operational stability, mechanical flexibility, and decent biocompatibility, organic mixed ionic–electronic conductors have shown great potential as implantable electrodes for neural recording/stimulation and as active channels for signal switching/amplifying transistors. Nonetheless, no studies exist on the general design rule for high-performance

Uterine factor infertility is increasingly common in modern society and has severely affected human life and health. However, the existing biomaterial scaffold-mediated system remains limited in efficiently uterus recovery, leading to low pregnancy rate and live birth. Here, we demonstrate a reconstructable uterus-derived materials (RUMs) by combing with uterus-derived extracellular matrix (ECM) and

Controlling self-assembly of nanocomposites is a fundamental challenge with exciting implications for next-generation advanced functional materials. Precursors for composites can be generated photochemically, but limited insight in the underlying processes have hindered precise hands-on guidance. In this study, light-controlled nucleation and growth is demonstrated for self-assembling composites according
