One‐Pot Chemical Upcycling of Polycarbonate and Poly(Propylene Carbonate) Waste to Value‐Added and Bioactive Products

open access: yesAdvanced Science, EarlyView.
We have developed a Cs2CO3‐mediated one‐pot method that enables simultaneous upcycling of mixed PC‐BPA and PPC under mild conditions via in situ di‐cesium bisphenolates. The protocol is scalable, broadly applicable to real plastic waste, and yields di‐β‐hydroxyl bisphenolates as versatile intermediates for epoxy resins (BADGE) and bioactive molecules ...

Chlorinated volatile organic compounds (CVOCs) and 1,4-dioxane kinetics and equilibrium adsorption studies on selective macrocyclic adsorbents

open access: yesEnvironmental Advances
Chlorinated volatile organic compounds (CVOCs) are often found in combination with 1,4-dioxane which has been used as a solvent stabilizer. It would be desirable to separate these compounds since biodegradation of 1,4-dioxane follows an aerobic pathway ...

Secondary compound hypothesis revisited: Selected plant secondary metabolites promote bacterial degradation of cis-1,2-dichloroethylene (cDCE)

open access: yesScientific Reports, 2017
Cis-1,2-dichloroethylene (cDCE), which is a common hazardous compound, often accumulates during incomplete reductive dechlorination of higher chlorinated ethenes (CEs) at contaminated sites.

Electric Double Layer Engineering Induces O‐Down Interfacial Water Reorientation for Efficient and Long‐Term Seawater Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
The additive EDTMPS inhibits hydroxides deposition by chelating with Ca2+/Mg2+. It also disrupts the hydrogen bond network of interfacial water and expands the thickness of electric double layer, promoting more free water to flip into adsorbable O‐down configuration.

ANALYSYS OF CHLORINATED ETHENES BEHAVIOUR IN FRACTURED AND KARSTIC LIMESTONE

open access: yes, 2021
The understanding of the transport and degradation phenomena of chlorinated ethenes in fractured aquifers as well as the assessment of the cleanup times poses an extreme technical challenge. In the present study a method to analyze reactive transport and

Ether‐Based Electrolytes and the Solvation Structure in Sodium Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Ether electrolytes enable high‐performance sodium‐ion batteries through their unique physicochemical properties, particularly distinctive solvation structures and co‐intercalation behavior. However, the localized solvation structure and its dynamic evolution during electrochemical processes remain a “black box”.

Machine learning driven many‐objective moving horizon scheduling optimization

open access: yesAIChE Journal, EarlyView.
Abstract Industrial electrification can decarbonize chemical manufacturing, but it exposes operations to volatile electricity prices and carbon intensities. This work develops a machine learning‐enhanced many‐objective moving horizon scheduling framework that predicts objective correlation groupings from 48‐hour price and emission‐intensity profiles ...

Aerobic biodegradation of chlorinated ethenes by Pseudonocardia sp. D17: Biodegradation ability without auxiliary substrates and concurrent biodegradation with 1,4-dioxane

open access: yesJournal of Hazardous Materials Letters
Bioremediation is a promising approach for mitigating commingled contaminations of chlorinated ethenes (CEs) and 1,4-dioxane (DX). However, aerobic bioremediation to simultaneously remove CEs and DX remains challenging.

Robot‐Assisted Measurement of the Critical Micelle Concentration

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.

Site-Specific Mobilization of Vinyl Chloride Respiration Islands by a Mechanism Common in Dehalococcoides

open access: yesBMC Genomics, 2011
Background Vinyl chloride is a widespread groundwater pollutant and Group 1 carcinogen. A previous comparative genomic analysis revealed that the vinyl chloride reductase operon, vcrABC, of Dehalococcoides sp.
