WebJan 27, 2024 · This study develops a terahertz (THz) chemical microscope (TCM) that visualizes the distribution of chemical reaction on a silicon-based sensing chip. This chip, called the sensing plate, was fabricated by depositing Si thin films on a sapphire substrate and thermally oxidizing the Si film surface. The Si thin film of the sensing plate was … WebApr 10, 2024 · Few-shot learning techniques, such as meta-learning, have great potential in helping chemists explore the new reaction chemical space. However, the structure of random forest is non-differential, which is hard to combine with the gradient-based techniques in few-shot learning. Thus random forest cannot be directly optimized by few …

Web3 hours ago · Pasek examined in a study how high-energy events, such as lightning, can cause unique chemical reactions and, in this instance, result in a new material which is transitional between space minerals and those found on Earth. The study is published in the journal Communications Earth & Environment. WebDNA nanotechnology offers a fine control over biochemistry by programming chemical reactions in DNA templates. Coupled to microfluidics, it has enabled DNA-based reaction-diffusion microsystems with advanced spatio-temporal dynamics such as traveling waves. The Finite Element Method (FEM) is a standard tool to simulate the physics of such … ipn disease
