A knowledge based infrared camera system for invisible gas detection utilizing image processing techniques

AuthorsAuthors and affiliations HyungJun Kim Open Access Original Research First Online: 12 June 2019 51 Downloads Abstract An infrared camera system for real-time monitoring of invisible methane gas

Event-to-event intensification of the hydrologic cycle from 1.5 °C to a 2 °C warmer world

The Paris agreement was adopted to hold the global average temperature increase to well below 2 °C and pursue efforts to limit it to 1.5 °C. Here, we investigate the event-to-event hydroclimatic intensity, where an event is a pair of adjacent wet and dry spells, under future warming scenarios. According to a set of targeted multi-model large ensemble experiments, event-wise...

Synergistic interaction of Re complex and amine functionalized multiple ligands in metal-organic frameworks for conversion of carbon dioxide

Hyungjun Kim Kyung Min Choi Jeung OPEN A metal-organic framework (MOF) is composed of secondary building units (SBUs) of metal ions and organic ligands to link each SBU. Moreover, the photosynthetic

Real-time detection of chlorine gas using Ni/Si shell/core nanowires

We demonstrate the selective adsorption of Ni/Si shell/core nanowires (Ni-Si NWs) with a Ni outer shell and a Si inner core on molecularly patterned substrates and their application to sensors for the detection of chlorine gas, a toxic halogen gas. The molecularly patterned substrates consisted of polar SiO2 regions and nonpolar regions of self-assembled monolayers of...

Probing Conformational Changes of Ubiquitin by Host–Guest Chemistry Using Electrospray Ionization Mass Spectrometry

We report mechanistic studies of structural changes of ubiquitin (Ub) by host–guest chemistry with cucurbit[6]uril (CB[6]) using electrospray ionization mass spectrometry (ESI-MS) combined with circular dichroism spectroscopy and molecular dynamics (MD) simulation. CB[6] binds selectively to lysine (Lys) residues of proteins. Low energy collision-induced dissociation (CID) of the...

Response of the Primary Auditory and Non-Auditory Cortices to Acoustic Stimulation: A Manganese-Enhanced MRI Study

Structural and functional features of various cerebral cortices have been extensively explored in neuroscience research. We used manganese-enhanced MRI, a non-invasive method for examining stimulus-dependent activity in the whole brain, to investigate the activity in the layers of primary cortices and sensory, such as auditory and olfactory, pathways under acoustic stimulation...

Java experiments for introductory cognitive psychology courses

Interactive on-line experiments provide a unique and useful method for communicating material to students that is otherwise cumbersome and often confusing. The Java programming language is particularly suited for Internet-based programming applications of this sort because it bypasses many technical issues, including resource availability, security, and cross-platform...
