#AichLENS published journal article on nanohybrid toxicity in ACS Sustainable Chemistry & Engineering
Nanomaterial conjugations are performed to enhancing their application performance such as catalytic activities or contaminant removal efficiency. However, conjugation of two or more materials to produce nanohybrids may lead to unprecedented toxicological behavior. #AichLENS group has shown in this paper that the nanohybrids show significantly different toxicological behavior that their parent materials, and also the toxicity of nanohybrids cannot be predicted either from the mixture of the parent materials or from the individual material toxicity.
#AichLENS published a book chapter on the application of iron-based nanohybrids for water and soil remediation
New generations of nanocomposites and nanohybrids containing iron nanoparticles are becoming very important for soil and water remediation. They provide multifunctional properties and can enhance performances. However, these emerging properties of nanohybrids can also create potential concerns for environmental and human health risks. This important and emerging area of research is discussed in the new book chapter titled 'Application of Nanozerovalent Iron for Water Treatment and Soil Remediation: Emerging Nanohybrid Approach and Environmental Implications' co-authored by Dr. Nirupam Aich and 2nd Year PhD student Arvid Masud in the book 'Iron Nanomaterials for Water and Soil Treatment'.
#AichLENS published an article in the journal of Environmental Science & Technology
#AichLENS group has just published an article in the journal of Environmental Science & Technology titled 'Investigating and Modeling the Transport of the ‘New-Horizon’ Reduced Graphene Oxide—Metal Oxide Nanohybrids in Water-Saturated Porous Media'. This paper, for the first time, shows how to model the complex behavior of multifunctional nanohybrids in the porous media. Dr. Aich is a coauthor of the paper, and this is published in collaboration with the USEPA.
#AichLENS Published an Article in Journal of Nanoparticle Research
#AichLENS group has recently published an article in the Journal of Nanoparticle Research titled 'Shape matters: Cr(VI) removal using iron nanoparticle impregnated 1-D vs 2-D carbon nanohybrids prepared by ultrasonic spray pyrolysis'. This paper describes the effect of dimensionality of 1-D CNT vs 2-D graphene on the chromium removal performance of the nanocarbon-iron hybrid materials. 1st year PhD student Arvid Masud is the leading author in this paper. Dr. John Atkinson's group at UB is the collaborator in this project. Online version coming soon!
During Fall 2017, Dr. Aich gave invited talks the Environmental Engineering programs at the Rochester Institute of Technology (RIT), Ohio State University (OSU), and University of California Los Angeles (UCLA). He presented the recent works in #AichLENS on the environmental application of multifunctional nanomaterials.

New Book Chapter Published by #AichLENS Group
#AichLENS group has published a book chapter titled 'Dimensional Variations in Nanohybrids: Property Alterations, Applications, and Considerations for Toxicological Implications' in the book 'Anisotropic and Shape-Selective Nanomaterials: Structure-Property Relationships'. Dr. Aich is the leading author in the chapter while M.S. Student Arvid Masud is a coauthor. This chapter is a collaborative work with Drs. Navid Saleh and Jaime Plazas-Tuttle from University of Texas at Austin and Dr. Tara Sabo-Attwood from University of Florida.
Hybridization of nano-scale entities prepare higher dimensional ensemble materials with multifunctionality. Such hierarchical complex materials though are engineered with output properties in mind, these evolved nanostructures possess unique shapes and physicochemical attributes. Nanotoxicological considerations hinge on physical size and shape factors; thus, dramatic alterations to shape and dimensionality of ensemble nanohybrids (NHs) necessitate careful evaluation of this ‘horizon’ material class. This chapter reviews size/shape/dimensionality variations of nanomaterials due to hybridization and discusses property alteration of these NHs, relevant to applications and nanotoxicology. The chapter also discusses nano-bio interactions of novel nanohybrids in relation to their size, shape, and dimensionality, and outlines future research needs and strategies.
