Effects of talc particle size on the non-isothermal crystallization kinetics and activation energy of isotactic polypropylene-based composites

eXPRESS Polymer Letters
This study investigates the non-isothermal crystallization behavior of isotactic polypropylene (iPP) reinforced with two types of talc fillers: micrometric talc (μ-talc) and standard talc (S-talc).

Ternary Crosslinking Builds Nanosheet Hard Carbon and Interfacial Polarization Regulates Na⁺ Kinetics in Hard Carbon Anodes

Carbon Energy, EarlyView.
Nanosheet Hard Carbon for Fast Na+ Storage ABSTRACT Hard‐carbon anodes for sodium‐ion batteries are often constrained by low initial Coulombic efficiency, severe interfacial polarization, and sluggish Na⁺ kinetics, especially when porosity engineering amplifies electrolyte consumption.

Weak‐Solvent‐Coordination Inducing MnNCN Preferential Orientation Toward High‐Capacity and Fast‐Charge Lithium‐Ion Storage

Carbon Energy, EarlyView.
Preferentially oriented MnNCN nanosheets with high active (003) facets were synthesized by an aqueous weak solvent‐coordination strategy, and highly integrated MnNCN/CNT composite was in‐situ constructed as a high‐capacity fast‐charging anode. NCM811//MnNCN/CNT pouch cell exhibits a high energy density of 325 Wh kg−1 with a long cycle‐life over 200 ...

Impact of A‐Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL‐DRM)

Chemistry – A European Journal, EarlyView.
Sr doping regulates oxygen exchange and methane activation in LaFeO3, suppressing nonselective CH4 cracking and coke formation during CL‐DRM. La0.7Sr0.3FeO3 provides the optimal balance, delivering ∼40% CH4 conversion, an H2/CO ratio of 2, and >95% carbon balance.

Impact of Ether Side‐Chain Length and Anion Structure on the Physicochemical and Electrochemical Properties of Tetrahydrothiophenium Ionic Liquids

Chemistry – A European Journal, EarlyView.
Tetrahydrothiophenium (Tht) ionic liquids bearing alkyl or ether side chains (one to four oxygen atoms) with FSA or TFSA anions were synthesized. Longer ether chains raised glass transition temperatures and viscosity while lowering conductivity. Short‐ether‐chain ILs, especially FSA‐based ones, exceeded 10−3 S cm−1 at 25°C, comparable to pyrrolidinium ...
