  • Functional materials for sustainable technologies

    We explore solar reflective, energy attenuation and icephobic coatings through the design and synthesis of asymmetric polymer chain and hybrid latex particle structures with the aim to reduce energy consumption. The innovative aspect of this study originates from formation of discrete assembling of clusters in nanoscale, which induce unusual properties, e.g. high reflectivity to near infrared...

  • pH-Sensitive Vesicles with Tunable Membrane Permeability for Drug Delivery

    By synergizing multiscale simulations, we investigate the assembly of amphiphilic copolymers PAE-g-PEGLA into vesicles and the loading/release of DOX∙HCl. During the formation of bilayer-structured vesicles, the interior size and membrane thickness are substantially affected by the exchange rate between tetrahydrafuran and water. At pH = 7, DOX∙HCl is loaded into the vesicle interior and the...

  • Novel Asymmetric Functionalizations of Alkenes by Modular Cascade Biocatalysis

    Catalytic asymmetric transformation is of great importance in the preparation of chiral chemicals for the manufacturing of pharmaceuticals, agrochemicals, and specialty chemicals. Here, we develop three novel types of regio- and enantioselective multiple oxy- and amino-functionalizations of terminal alkenes via cascade biocatalysis to produce chiral α-hydroxy acids, 1,2-amino alcohols, and...

  • Enhanced hydrate formation kinetics at near ambient temperatures and moderate pressures - Application to natural gas storage

    SNG (Solidified Natural Gas) technology via clathrate hydrates for natural gas storage is suitable for large scale stationary storage of natural gas. To assess the scale-up potential of SNG technology, hydrate formation kinetics in presence of methane and 5.6 mol% tetrahydrofuran (THF) was investigated at moderate pressure and temperature conditions. A synergistic effect of kinetic promotion...

  • Organic NPs with Tunable Size for Evaluation of Blood-Brain Barrier Damage’

    Detection of blood-brain barrier (BBB) damage is important for the brain disease diagnosis. The most widely used probe, Evans blue, suffers from low specificity and high toxicity. In this work, organic nanoparticles (NPs) with aggregation induced emission characteristics and controlled sizes (60 nm, 30 nm and 10 nm) were synthesized by modified nanoprecipitation methods. In a rat model of...

  • Book on Chemical Process Retrofitting and Revamping: Techniques and Applications

    Chemical process plants operating today were designed in the past, perhaps optimally for conditions at that time. Although designed for 10 to 20 years, many plants continue to operate for much longer. It is imperative to improve their performance to meet current environmental, technological and economic targets. Hence, suitable modifications in the process equipment and configuration have to be...

  • Crab Shell to Chemicals!

    A new route has been developed to transform chitin into acetic acid and pyrrole, which is selected as ACS Editor’s Choice and featured as the front cover of ACS Sustainable Chemistry & Engineering. Global shellfishery waste generation is from 6 to 8 million metric tons annually. Chitin, as a major component in crustacean shells, is the second most abundant biopolymer on Earth, having the...
