New paper published in Desalination on position-resolved ion concentration from operando X-ray transmission. This collaborative work introduces position-resolved operando synchrotron X-ray transmission to directly map local ion concentration changes inside a working capacitive deionization (CDI) cell – separating contributions from the flow channel electrolyte and the two nanoporous electrodes. Using a CsCl model electrolyte, we […]

New paper published in ACS Energy Letters on interlayer-tailored Alkyl-MXenes for selective electrochemical lithium-ion extraction. The paper reports a two-step electrochemical lithium-ion extraction strategy using interlayer-tailored Ti3C2Tx MXene electrodes. By pre-intercalating long-chain organic molecules (hexadecylamine, HDA, and decyltrimethylammonium, C10), the MXene interlayer environment is tuned to favor Li+ over competing Na+, improving both selectivity and […]

New paper published in ACS Applied Energy Materials on the use of quaternary electrolytes for enhanced capacitive energy storage. This collaborative work explores quaternary electrolytes (two distinct cations and two distinct anions) as a practical strategy to improve electrical double-layer capacitors – combining a solvable theoretical pore-charging framework with experimental validation using [EMIM][BF4] mixed with […]

New paper published in Rare Metals on oxygen vacancy–engineered Bi–Mn–Al oxide / reducedgraphene oxide for high–performance supercapacitors. This work introduces oxygen-vacancy-rich Bi2O3/Mn3O4/Mn2AlO4(OV)/rGO multiphase heterostructures that accelerate ion transport and boost conductivity, enabling higher operating voltage and markedly improved supercapacitor energy and power performance (supported by DFT).

New paper published in ACS Sustainable Chemistry & Engineering. We present a mildly synthesized aluminum layered double hydroxide (Al-LDH) electrode that couples chemical adsorption with electrochemical release to recover lithium at neutral pH, eliminating harsh acids or bases and minimizing secondary pollution. It achieves an average Li+ uptake of 57.6 mg/g with strong Li+ over […]
