A highly efficient catalytic system without transition metals has been developed for aerobic alcohol oxidations. Under the optimal reaction conditions, various substrates were converted into their corresponding carbonyl compounds by air with TEMPO/Br2/NaNO2 as catalyst, especially oxidation of benzylic alcohols to benzaldehydes in high yields.
Abstract Hard carbon has the potential to serve as a high‐capacity anode material for sodium‐ion batteries (SIBs), however, its Na + storage mechanism, particularly on low plateau, remains controversial. To overcome this issue, two types of hard carbons with different microstructures are employed and relationship between behaviors is evaluated. By combination operando X‐ray diffraction, ex situ Raman spectroscopy, NMR, theoretical calculation, it found that sodium capacities in plateau...
Abstract Highly concentrated electrolytes (HCEs) significantly improve the stability of lithium metal anodes, but applications are often impeded by their limitation density, viscosity, and cost. Here, fluorobenzene (FB), an economical hydrocarbon with low density is demonstrated as a bifunctional cosolvent to obtain novel FB diluted highly electrolyte (FB‐DHCE). First, addition suppresses decomposition dimethoxyethane (DME) on Li strengthening interactions DME FSI − around + . Second,...
It is urgent to seek high performance solid polymer electrolytes (SPEs) via a facile chemistry and simple process. The lithium salts are composed of complex anions that stabilized by Lewis acid agent. This can initiate the ring opening polymerization. Herein, self-catalyzed strategy toward synthesis crosslinked poly(ethylene glycol) diglycidyl ether-based electrolyte (C-PEGDE) presented. manifested possesses superior electrochemical stability window up 4.5 V versus Li/Li+ considerable ionic...
Abstract Na superionic conductor structured 3 V 2 (PO 4 ) cathodes have attracted great interest due to their long cycling lifespan and high thermal stability rendered by the robust 3D framework. However, practical application is still hindered cost of raw materials limited energy density. Herein, a doping strategy with low‐cost Fe 2+ developed activate 4+ /V 5+ redox, in an attempt increase density phosphate cathodes. It also revealed that reversible activation redox related positions (Na1,...
FeCl3-TEMPO-NaNO2 catalyses the selective and mild aerobic oxidation of a broad range alcohols to corresponding aldehydes ketones.
A highly efficient catalytic system without transition metals in water has been developed for aerobic oxidations of benzylic alcohols. The newly catalyst could oxidize alcohols and heteroaromatic analogues with 1 mol % TEMPO as a amount 1,3-dibromo-5,5-dimethylhydantoin NaNO2 cocatalysts. Under the optimal conditions, various be converted into their corresponding aldehydes or ketones high yields.
Glycans play vital roles in nearly all life processes of multicellular organisms, and understanding these activities is inseparable from elucidating the biological significance glycans. However, glycan research has lagged behind that DNA protein due to challenges posed by structural heterogeneity isomerism (i.e., structures with equal molecular weights) lack high-efficiency analysis techniques. Nanopore technology emerged as a sensitive single-molecule biosensor, shining light on analysis....
Click chemistry has been successfully extended into the field of preparation functionalized HPLC packings, proving a novel facile and efficient strategy for covalently bonding stationary phases onto grade silica beads; potential demonstrated by "Click I–IV" columns preliminary results in separation sugars.
A direct line: organocatalytic asymmetric vinylogous Michael addition of α,β-unsaturated γ-butyrolactams with ketones has been developed (see scheme; Boc=tert-butoxycarbonyl, Trp=tryptophan, Ts=4-toluenesulfonyl). The resulting products, 5-substituted 3-pyrrolidin-2-ones, could be obtained in excellent yields enantio- and diastereoselectivity. Detailed facts importance to specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or...
Li10GeP2S12 (LGPS) is a new solid electrolyte of the highest Li ionic conductivity reported as now. An anisotropic 3D transport network consisting an ultrafast 1D diffusion tunnel and fast in-plane 2D pathways was previously predicted by molecular dynamics simulations. In this paper, we have studied in detail ion LGPS multiple solid-state NMR methods. Two different motion processes, characterized apparently activation energies 0.16 eV 0.26 eV, were unambiguously probed both 7Li 31P assigned...
Vanadium hexacyanoferrate (VHCF) with an open-framework crystal structure is a promising cathode material for rechargeable aqueous metal-ion batteries owing to its high electrochemical performance and easy synthesis. In this paper, vanadium cathodes were first used constructing sodium-ion (VHCF/WO3) tested in the new-type electrolyte (NaP-4.6) consisting of polyethylene glycol (PEG)/H2O/NaClO4 low H+ concentration (molar ratio [H2O]/[Na+] 4.6), which has stability at current density as 1000...
Mulberroside A is a natural polyhydroxylated stilbene compound present at relatively high abundance in the roots and twigs of Morus alba L. It known for its nephroprotective, hypoglycemic, antidiabetic effects. Because metabolite, oxyresveratrol, possessed purported anti-inflammatory neuroprotective effects, we proposed that mulberroside may elicit effects can be used treatment brain ischemic injury. Therefore, decided to investigate pharmacological properties primary culture rat cortical...
The limitations of conventional organic liquid electrolytes such as sodium dendrite growth, serious side reactions, and leakage hinder the development sodium–metal batteries (SMBs). In this work, a novel sodium–poly(tartaric acid)borate (NaPTAB) salt with low cost environmental friendliness was synthesized by an aqueous phase synthesis method. NaPTAB combined poly(vinylidene fluoride)–hexafluoropropylene (PVDF–HFP) to form NaPTAB-SM, then NaPTAB-SM swelled in PC solution obtain single...
