The New York and New Jersey Society of Applied Spectroscopy (SAS) has postponed its live meetings until the country gets back to a normal work schedule. In the interim, an online meeting schedule has been developed as a way to maintain the connection.
The New York and New Jersey Society of Applied Spectroscopy (SAS) has postponed its live meetings until the country gets back to a normal work schedule. In the interim, an online meeting schedule has been developed as a way to maintain the connection.
To kick off the new schedule, the The NY–NJ SAS regional section will continue to offer meetings online for all members who want to participate. To provide feedback or join the online meetings, please email Debbie Peru at debperu@outlook.com. A link to the webinar will be provided. SAS held an online meeting on April 29. Guest speaker Ugochukwu Ikeogu, a post-doctoral research associate at Cornell University (Ithaca, New York), discussed the use of low-cost portable near infrared (NIR) spectrophotometers for phenotyping and quality control testing for a range chemical and physical parameters in cassava root and ground powder. The title of his talk was “Portable NIRS: A Fresh Perspective in Cassava Phenotyping.”
Ikeogu is the project manager of the “VitisGen2” project in the horticulture section at Cornell University. He received his PhD from Cornell University in 2018 from the Section of Plant Breeding and Genetics. His research focused on high throughput phenotyping and genomics-assisted improvement in cassava.
Ugochukwu Ikeogu
Ikeogu developed a passion for phenotyping as a way to bridge the gap between advanced genomics technology and the need for more rapid and precise phenotyping for improving plant breeding, especially quantitative traits of plants. He initiated the rapid and field-based calibration and deployment of a portable visible and NIR (vis/NIR) spectrometer in line with strategies for genomic selection implementation in cassava. In his first post-doctoral appointment, he contributed to a pilot remote sensing effort using thermal and hyperspectral imaging, as well as transcriptomic and metabolomic profiling of stress responses in a model plant for a living surveillance to enhance national security (LiSTENS) initiative. Today, his research focuses on the adoption of new phenotyping and molecular marker tools for the improvement of wine, table, and raisin grapes under a multi-institutional research collaboration funded by the United State Department of Agriculture–National Institute of Food and Agriculture (USDA-NIFA) Specialty Crop Research Initiative.

Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
Deep Level Transient Spectroscopy Reveals Influence of Defects on 2D Semiconductor Devices
April 25th 2024A recent study used deep level transient spectroscopy to investigate the electrical response of defect filling and emission in monolayer metal-organic chemical vapor deposition (MOCVD)-grown materials deposited on complementary metal-oxide-semiconductor (CMOS)-compatible substrates.
Single Cell and Microplastic Analysis by ICP-MS with Automated Micro-Flow Sample Introduction
April 25th 2024Single cell ICP-MS (scICP-MS) is increasingly seen as a powerful and fast tool for the measurement of elements in individual cells, mainly due to the high sensitivity and selectivity of ICP-MS. Analysis is performed in the same way as single nanoparticle (spICP-MS) analysis, which has become a well-established technique for the analysis of nanoparticles and particles.
