Design of high SERS sensitive substrates based on branched Ti nanorods (open access)

Design of high SERS sensitive substrates based on branched Ti nanorods

Article reports a rational design of branched titanium (Ti) nanorods formed by glancing angle physical vapor deposition and their applications as substrates for surface-enhanced Raman scattering (SERS). The authors investigation provides a mechanism to fabricate sensitive SERS sensors of Ti nanorods that are known to be thermally and chemically stable and compatible with silicon-based electronics.

CPS: Medium: Integrating sensors, controls, and ecotoxicology with decoupled aquaponics using brackish groundwater and desalination concentrate for sustainable food production (open access)

CPS: Medium: Integrating sensors, controls, and ecotoxicology with decoupled aquaponics using brackish groundwater and desalination concentrate for sustainable food production

Data management plan for the grant, "CPS: Medium: Integrating sensors, controls, and ecotoxicology with decoupled aquaponics using brackish groundwater and desalination concentrate for sustainable food production." This project aims to develop a cyber-physical system (CPS) testbed of integrated sensors, controls, machine learning, and ecotoxicology tools to engineer sustainable food production systems based on aquaculture using brackish water. The testbed includes an automated recirculating aquaculture system integrated with a real-time ecotoxicology system, implementing the system using desalination concentrate to demonstrate that brackish groundwater desalination costs can be offset by using its byproducts for profitable food production. This project will engage students of the local communities in three major ways: developing an exhibit and activity emphasizing interdisciplinary CPS research conducted during the academic year, offering summer research experiences to students from underrepresented groups, and participating in STEM outreach events targeting underrepresented groups.

Taller de Trabajo Sobre Modelaje de Cultivos: Entrenamiento y Calibracion Informe

Report on a Modeling Crop and Climate Change workshop. The objectives of the workshop were: 1) train Venezuelan scientists in the use of agricultural models IBSNAT program (International Benchmark Sites Network for Agrotechnology Transfer), including discussions about their applicability and the acquisition of knowledge about the data needed for proper simulation and validation, 2) Calibrate the model of maize (CERES) for different cultivars and different regions of Venezuela using data from soil and climate corresponding to various tests, 3) Carry out model simulations under various climate scenarios to assess their potential effects on crops, 4) To strengthen the cooperation between users of IBSNAT models to make necessary tests to get a better database application thus facilitating validation and calibration of these models, and 5) To establish plans for future agricultural and meteorological research in the context of global climate change.
