Extractive Distillation Configuration for Nitric Acid Dehydration Using Sulfuric Acid as a Solvent

, 2020
In this work, an extractive distillation configuration for dehydration of nitric acid is proposed with sulfuric acid as a solvent. Thermodynamic modeling of the vapor–liquid equilibrium of binary and ternary systems of nitric acid/water/sulfuric acid is ...

Dehydration System for organic solvents by vapor permeation

membrane, 2001
UBE's process is based on the dehydration in vapor phase. Use of BPDA-polyimide makes it possible to produce a membrane with characteristics that include good water vapor permeation and excellent durability. The ethanol dehydration process has been used in UBE's chemical plant since 1990, resulting in reduced operating cost and improved operational ...

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Dehydration of cellulose to levoglucosenone using polar aprotic solvents

Energy & Environmental Science, 2015
Herein, we report an approach to produce levoglucosenone (LGO) from cellulose in yields up to 51% under mild reaction conditions (170–230 °C; 5–20 mM H2SO4) using polar, aprotic solvents such as tetrahydrofuran (THF).

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

Advanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Solvent-mediated polymorphism and characterisation of inhaled pharmaceuticals [PDF]

, 2019
The use of polar anti-solvents for the crystallisation of lactose from 10% (w/v) aqueous solutions has been investigated. Crystal growth was observed at 50-65% antisolvent content and showed a morphological transition from polyhedral to needle-like habit

TREATING THE USED AUTOMOBILES OILS USING SOLVENTS

Iraqi Journal of Chemical and Petroleum Engineering, 2010
Used automobile oils were subjected to filtration to remove solid material and dehydration to remove water, gasoline and light components by using vacuum distillation under moderate pressure, and then the dehydrated waste oil is subjected to extraction ...

Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...
