Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

Advanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Solvent‐Induced Covalent Bond Softening Boosts Battery Voltage

Angewandte Chemie, EarlyView.
The strong attractive interaction between the nucleophilic center of the solvent and the electrophilic region of the covalently bonded cathode fragment triggers charge transfer. This results in the electron population in the antibonding orbital of the covalent bond, leading to bond weakening and elongation, and consequently increasing the cathode ...

Observation of Raman G-band splitting in top-doped few-layer graphene

, 2010
An experimental study of Raman scattering in N-layer graphene as a function of the top layer doping is reported. At high doping level, achieved by a CHF_3 plasma treatment, we observe a splitting of the $G$ band in the spectra of bilayer and 4-layer ...

A selected ion flow tube study of the reactions of gas-phase cations with PSCl3 [PDF]

, 2004
A selected ion flow tube was used to investigate the positive ion chemistry of thiophosphoryl chloride, PSCl\(_3\). Rate coefficients and ion product branching ratios have been determined at room temperature for reactions with nineteen cations ; H\(_3\)O\

Electrically Assisted Thermal Stamping of Tunable Carbon‐Based Nanofilms for Direct Fabrication of Hydrophobic, Energy Harvesting, and Sensing Devices

Advanced Materials, EarlyView.
Schematic illustration of the electrically assisted thermal stamping (EATS) method for direct fabrication of carbon‐based nanofilms and their multifunctional applications. Localized Joule heating triggers simultaneous exfoliation, reduction, and fluoropolymer incorporation under ambient conditions, yielding tunable carbon‐based thin‐film coatings ...

Electrochemical studies of ciprofloxacin and its interaction with DNA(环丙沙星与DNA相互作用的电化学研究)

Zhejiang Daxue xuebao. Lixue ban, 2007
研究了环丙沙星(CFX)在自制的浸蜡石墨电极上的电化学特性，示差脉冲伏安法发现CFX在0.88 V处有一明显的氧化峰，DNA的加入使这一氧化峰明显减弱.采用所推导的电化学公式对实验数据进行了非线性拟合，同时获得了CFX与DNA的结合常数（K=1.36105（mol/L）-1）和结合位点数（s= 1.94），并探讨了CFX与小牛胸腺DNA的结合机理.

Relatively low temperature defluorination and carbon coating in CFx by dimethyl silicone oil/polyethylene glycol for enhancing performance of lithium primary battery

Electrochemistry Communications
Because of the presence of electrochemically inactive C-F2 bond and poor electronic conductivity of C-F, the discharge performance of lithium fluorocarbon (Li/CFx) batteries is limited, despite their extensive use in commercial fields.
