Preparation and characteristics of polyurethane made with polyhydric alcohol‐liquefied rice husk

26-Oct-2017 | Wen‐Jau Lee, Chao‐Yun Yu, Yi‐Chun Chen, Journal of Applied Polymer Science, 2017

ABSTRACT The limited availability of fossil resource is causing the urgent need to get renewable chemicals. Solvent liquefaction can convert rice husk into bio‐based chemicals. Rice husk was liquefied in polyhydric alcohol catalyzed by sulfuric acid under atmospheric pressure. The viscosity, ...

Elucidating the Limiting Steps in Sulfuric Acid–Base New Particle Formation

23-Oct-2017 | Jonas Elm, Journal of Physical Chemistry A, 2017

The molecular interactions between sulfuric acid (sa) and methylamine (ma) are investigated using computational methods. The molecular structures and vibrational frequencies of (sa)a(ma)b clusters, with a, b ≤ 4, were obtained with the ωB97X-D functional using a 6-31++G(d,p) basis set. The ...

Quantum Chemical Rovibrational Analysis of the HOSO Radical

13-Oct-2017 | Ryan C. Fortenberry; Joseph S. Francisco; Timothy J. Lee, Journal of Physical Chemistry A, 2017

syn-HOSO is the most stable form of hydrogenated sulfur dioxide, a possible intermediate in the creation of sulfuric acid. Recent work has characterized the structure and rotational constants, but the present work provides new insights into the vibrational spectra of this molecule. The central ...

Life-Cycle Cost and Environmental Assessment of Decentralized Nitrogen Recovery Using Ion Exchange from Source-Separated Urine through Spatial Modeling

12-Oct-2017 | Olga Kavvada; William A. Tarpeh; Arpad Horvath; Kara L. Nelson, Environmental Science & Technology, 2017

Nitrogen standards for discharge of wastewater effluent into aquatic bodies are becoming more stringent, requiring some treatment plants to reduce effluent nitrogen concentrations. This study aimed to assess, from a life-cycle perspective, an innovative decentralized approach to nitrogen ...

Phase transition identification of cellulose nanocrystal suspensions derived from various raw materials

20-Sep-2017 | Yuanyuan Zhang, Qiaoyun Cheng, Chunyu Chang, Lina Zhang, Journal of Applied Polymer Science, 2017

ABSTRACT Cellulose nanocrystals (CNCs) as attractive nanomaterials are widely distributed in higher plants, algae, and marine animals. Herein, three kinds of CNCs were isolated by sulfuric acid hydrolysis from cotton pulp, algae, and tunicate cotton, respectively. Their morphologies and size ...
