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 ...

Lanthanide Centered and Circular Polarized Luminescence (CPL) From Tb(III) Complexes Made From Structurally Simple Methoxy‐Phenyl and Phenol‐Derived Pyridyldiamide (pda) Ligands

Chemistry – A European Journal, EarlyView.
The development of chiral pda derived methoxy ligands L1a [1(R,R)] and L1b [1(S,S)], along with their phenol derivatives L2a [2(R,R)] and L2b [2(S,S)], and their respective Tb(III) complexes is described. These Tb‐complexes exhibited Tb(III)‐centered emission upon and their chiroptical properties were probed by using both CD and CPL spectroscopy ...

Rapid and Reusable Amino Acid–Derived MOFs for the Removal of Estrogenic Hormones From Real Water Matrices

Chemistry – A European Journal, EarlyView.
A family of amino‐acid–derived MOFs enables ultrafast (>90–95% in 30 s) simultaneous removal of four estrogenic contaminants from water under SPE conditions. A leucine‐based MOF shows excellent regenerability and robustness in real samples, with structural evidence revealing efficient hormone encapsulation.

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 ...

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Aqueous Supercapacitor with Wide‐Temperature Operability and over 100,000 Cycles Enabled by Water‐in‐Salt Electrolyte

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
This study presents a symmetric supercapacitor with activated carbon electrodes and a “water‐in‐salt” electrolyte (WiSE) based on lithium perchlorate, offering over 100,000 cycles with over 90 % capacity retention. The supercapacitor operates efficiently from −20 to 80 °C, enhancing performance, stability, and all‐season operability.
