Thermophysical Properties and Reactions.

Netsu Bussei, 1993
反応により原料が生成物に変換される時には, 熱の発生または吸収が観測される。 この熱は, 原料と生成物のエンタルピーや内部エネルギーの差に相当する。 反応に伴う熱は, 反応機構の解明や反応装置の設計において重要であり, これを予測するためには, エンタルピーや内部エネルギーなどの熱物性を正確に評価しなければいけない。 ここでは, 最近, 水和物の解離エンタルピーを測定するために開発された熱量計について詳細に解説するとともに, その他いくつかの反応熱測定装置についても報告する。

Mechanisms of Laser Ablation in Liquids and Their Impact on the Efficiency of Nanoparticle Generation

Laser &Photonics Reviews, EarlyView.
Laser ablation in liquid enables nanoparticle synthesis from diverse materials but remains less energy‐efficient than ablation in air. This study quantifies the absorption‐corrected ablation efficiency and experimentally confirms redeposition as the key loss mechanism using pump‐probe microscopy.

Comparative Evaluation of R134a and HFO‐1234ze Cryogen Spray Cooling Using a Mouse Model With Controllable Epidermal Pigmentation

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Cryogen spray cooling (CSC) is critical for protecting the epidermis during laser dermatologic procedures. The widely used cryogen, R134a, has a high global warming potential (GWP), motivating interest in environmentally favorable alternatives such as HFO‐1234ze.

Role of High Fidelity Vs. Low Fidelity Experimental Data in Machine Learning Model Performance for Predicting Polymer Solubility

Macromolecular Rapid Communications, EarlyView.
The performance of machine learning models for classifying polymer solubility improves when a high‐fidelity experimental dataset is used compared to a low‐fidelity experimental dataset. This has important implications for justifying the value of spending additional time and resources preparing detailed experimental datasets.
