The mechanical properties and interfacial structures for aluminum matrix composites reinforced by nanometer-sized SiC-β particles has been studied using molecular dynamics (MD) simulation. The modified embedded atom methods, was implemented to describe the atomic interactions. The molecular model undergoes an annealing MD simulation from 300 K to 1000 K to reach its minimum energy point. Tensile tests were performed with periodic boundary conditions. The stress-strain relationship has been studied and elastic constants were predicted as well. The results were compared with those given by continuum-based finite element analysis (FEA) together with the experimental data available in the literatures. It showed ...

Intermetallic compounds are garnering increasing attention as efficient catalysts for improved selectivity in chemical processes. Here, using a ship-in-a-bottle strategy, we synthesize single-phase platinum-based intermetallic nanoparticles (NPs) protected by a mesoporous silica (mSiO2) shell by heterogeneous reduction and nucleation of Sn, Pb, or Zn in mSiO2-encapsulated Pt NPs. For selective hydrogenation of furfural to furfuryl alcohol, a dramatic increase in activity and selectivity is observed when intermetallic NPs catalysts are used in comparison to Pt@mSiO2. Among the intermetallic NPs, PtSn@mSiO2 exhibits the best performance, requiring only one-tenth of the quantity of Pt used ...


Nanomanufacturing Outside The Lab: A Case Study In Academic-Industry Partnerships, Ann Delaney, Eric Lindquist 2016 Boise State University

Nanomanufacturing Outside The Lab: A Case Study In Academic-Industry Partnerships, Ann Delaney, Eric Lindquist

Ann E. Delaney

One of the National Nanotechnology Initiative’s Signature Initiatives is Sustainable Manufacturing.  With over $20 billion invested in nanotechnology research and development by the US government since 2000, there is now an emphasis on transitioning from primarily fundamental research to work aimed at overcoming the barriers preventing these technologies from being successfully produced and integrated into devices manufactured at an industrial scale.
To date, much focus has been placed on the technical barriers to commercialization.  However, other barriers outside of the lab must also be addressed in order to achieve broad commercialization of nanotechnology. The Public Policy Research Center (PPRC ...


Calcium Phosphate As A Key Material For Socially Responsible Tissue Engineering, Vuk Uskoković, Victoria M. Wu 2016 Chapman University

Calcium Phosphate As A Key Material For Socially Responsible Tissue Engineering, Vuk Uskoković, Victoria M. Wu

Pharmacy Faculty Articles and Research

Socially responsible technologies are designed while taking into consideration the socioeconomic, geopolitical and environmental limitations of regions in which they will be implemented. In the medical context, this involves making therapeutic platforms more accessible and affordable to patients in poor regions of the world wherein a given disease is endemic. This often necessitates going against the reigning trend of making therapeutic nanoparticles ever more structurally complex and expensive. However, studies aimed at simplifying materials and formulations while maintaining the functionality and therapeutic response of their more complex counterparts seldom provoke a significant interest in the scientific community. In this review ...

Enhanced Adhesion Of Superhydrophobic Zno Surface, liqiu zheng Dr., Chan Kwaichow B. 2016 Albany State University

Enhanced Adhesion Of Superhydrophobic Zno Surface, Liqiu Zheng Dr., Chan Kwaichow B.

Georgia Journal of Science

The superhydrophobicity and the strong solid-liquid adhesion of the dually structured ZnO surface are attributed to the suitable size of microstructure and nanostructure. This phenomenon, so different from the Lotus effect, can be called the Petal effect— the super hydrophobicity and the enhanced solid-liquid adhesion coexist on the same surface. The Cassie impregnating model was proposed to understand the underlying reason.


Targeted Combination Treatment For Glioblastoma Multiforme (Gbm) Using Polymeric Nanoparticle, Praveena Velpurisiva, Michael Tilton, Brandon Piel, Prakash Rai 2016 University of Massachusetts Lowell

Targeted Combination Treatment For Glioblastoma Multiforme (Gbm) Using Polymeric Nanoparticle, Praveena Velpurisiva, Michael Tilton, Brandon Piel, Prakash Rai

UMass Center for Clinical and Translational Science Research Retreat

Glioblastoma Multiforme (GBM) is an aggressive cancer that originates from astrocytes and spreads to spinal cord and other parts of the brain. Increase in replication of glial cells leads to advantageous mutations in the tumor. In 2015 about 15,320 deaths were reported due to GBM. Five-year survival is less than 5% making GBM a dreadful cancer. Current treatment involves complex invasive surgery, followed by chemotherapy and radiation. There is a desperate unmet need for a targeted treatment of GBM with minimum damage to the surrounding normal tissue. Combination treatments are increasingly being used to target multiple hallmarks of cancer ...

UMass Center for Clinical and Translational Science Research Retreat

Rapid point-of-care (POC) diagnostic devices are needed for field-forward screening of severe acute systemic febrile illnesses such as dengue, Ebola, chikungunya, and others. Multiplexed rapid lateral flow diagnostics have the potential to distinguish among multiple pathogens, thereby facilitating diagnosis and improving patient care. We present a platform for multiplexed pathogen detection which uses gold or silver nanoparticles conjugated to antibodies to sense the presence of biomarkers for different infectious diseases. We exploit the size-dependent optical properties of Ag NPs to construct a multiplexed paperfluidic lateral flow POC sensor. AgNPs of different sizes were conjugated to antibodies that bind to specific ...


Remotely Triggered Polymeric Nanoparticles For The Treatment Of Triple Negative Breast Cancer, Rahul Jadia, Brandon Piel, Michael Tilton, Prakash Rai 2016 University of Massachusetts Lowell

Remotely Triggered Polymeric Nanoparticles For The Treatment Of Triple Negative Breast Cancer, Rahul Jadia, Brandon Piel, Michael Tilton, Prakash Rai

UMass Center for Clinical and Translational Science Research Retreat

Triple Negative Breast Cancer (TNBC) has the worst prognosis among all the sub-types of breast cancer. Currently no targeted treatment has been approved for TNBC management. While TNBC does not overexpress hormone receptors, it has been found to over express certain receptors like transferrin (TfR) or folate receptors. The aim of this research is to synthesize targeted polymeric nanoparticles for TNBC. MDA-MB-231 cells are used as a representative TNBC cell line in this study. Active targeting of TNBC is achieved by conjugating the nanoparticles to a peptide (Tr) that binds to the TfR. Photodynamic Therapy (PDT) using polymeric nanoparticles was ...

Three-Dimensional Modeling Of Percolation Behavior Of Electrical Conductivity In Segregated Network Polymer Nanocomposites Using Monte Carlo Method.Pdf, Heng Gu

Heng Gu

Polymer nanocomposites filled with carbon nanotubes are observed to present an onset of the insulator-to-conductor transition through previous experimental studies. In this work, numerical simulations based on Monte Carlo method are performed to investigate the percolation threshold. The conductive fillers are modeled as a three dimensional (3D) network of identical units dispersed in the polymer matrix. However, the distribution of the fibers is not uniform due to the existence of the emulsion particles. The effects of the aspect ratio and fiber length on the critical volume fraction are studied. Linearization is made to the logarithm of simulation results. The calculated ...
