Selective Electrochemical Reduction of CO2 to Metal Oxalates in Nonaqueous Solutions Using Trace Metal Pb on Carbon Supports Enhanced by a Tailored Microenvironment

open access: yesAdvanced Energy Materials, EarlyView.
Encapsulating trace lead (Pb) in carbon electrodes with a fluoropolymer tailors the microenvironment for carbon dioxide (CO2) reduction. This enhances efficiency and selectivity, offering a tunable approach to guide reaction pathways and improve product outcomes in electrochemical CO2 conversion.

Perioperative outcomes of esophagectomy after doublet versus docetaxel‐based triplet neoadjuvant chemotherapy in older patients: A nationwide inpatient database study in Japan

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
In this nationwide inpatient database study of 5229 patients aged 70–79 years who underwent esophagectomy for cancer after neoadjuvant chemotherapy, overlap propensity score weighting analysis showed that neoadjuvant docetaxel‐based triplet regimen (docetaxel, cisplatin, and 5‐fluorouracil) was not associated with a higher incidence of perioperative ...
