pH-Triggered Molecular Alignment for Reproducible SERS Detection via an AuNP/Nanocellulose Platform
(Nature, 2015-12-11)
The low affinity of neutral and hydrophobic molecules towards noble metal surfaces hinders their detection by surface-enhanced Raman spectroscopy (SERS). Herein, we present a method to enhance gold nanoparticle (AuNP) ...
Effects of inset floodplains and hyporheic exchange induced by in-stream structures on nitrate removal in a headwater stream
(Elsevier, 2016-10-15)
Stream restoration efforts in the United States are increasingly aimed towards water quality improvement, yet little process-based guidance exists to compare pollutant removals from different restoration techniques for ...
A Framework for Occupancy Tracking in a Building via Structural Dynamics Sensing of Footstep Vibrations
(Frontiers, 2017-11-06)
Counting the number of occupants in building areas over time—occupancy tracking— provides valuable information for responding to emergencies, optimizing thermal conditions or managing personnel. This capability is distinct ...
Environmental Information Improves Robotic Search Performance
(Virginia Tech, 2016)
We address the problem where a mobile search agent seeks to find an unknown number of stationary objects distributed in a bounded search domain, and the search mission is subject to time/distance constraint. Our work ...
Evaluation of Resiliency of Transportation Networks After Disasters
(The National Academies of Sciences, Engineering, and Medicine, 2012)
The resiliency of infrastructure, particularly as related to transportation networks, is essential to any society. This resiliency is especially vital in the aftermath of disasters. Recent events around the globe, including ...
Groundwater influence on water budget of a small constructed floodplain wetland in the Ridge and Valley of Virginia, USA
(Elsevier, 2015-12-01)
Study region: A floodplain in the headwaters of a tributary to the Chesapeake Bay, Ridge and Valley of the Eastern United States.
Study focus: This study investigated the influence of groundwater exchange in the annual ...
Fundamental mechanisms of focused ion beam guided anodization
(American Institute of Physics, 2010-11-01)
This paper is focused on understanding the fundamental mechanisms of focused ion beam guided anodization and the unique capabilities of generating new patterns based on such an understanding. By designing proper interpore ...
Intrusion Detection System for Applications using Linux Containers
(Springer, 2015-12-09)
Linux containers are gaining increasing traction in both individual and industrial use, and as these containers get integrated into mission-critical systems, real-time detection of malicious cyber attacks becomes a critical ...
The "threads" of biosystems engineering
(American Society of Agricultural and Biological Engineers, 2014)
The core concepts, or threads, of biosystems engineering (BSEN) are variously understood by those within the discipline but have never been unequivocally defined due to BSEN's early stage of development. This makes ...
Evolution of domain structures in Na1/2Bi1/2TiO3 single crystals with BaTiO3
(American Physical Society, 2011-02-16)
The domain structures of Na1/2Bi1/2TiO3-BaxTiO3 (NBT-x%BT) crystals for x = 0, 4.5, and 5.5 have been investigated by polarized light and piezoresponse force microscopies. The results show that BaTiO3 (i) refines the size ...
