The authors, who have more than two decades of combined experience teaching an atoms-first course, have gone beyond reorganizing the topics. They emphasize the particulate nature of matter throughout the book in the text, art, and problems, while placing the chemistry in a biological, ...
Chemistry_ An Atoms-Focused Approach -W. W. Norton & Company (2017) _部分4 1018 chapter 22 The Main Group Elements22.1 Main Group Elements and Human HealthHave you ever wondered how many of the elements in the periodic table are in the human body? Or wondered which of them are important...
An approach that combines NMR spectroscopy and inductively coupled plasma mass spectrometry (ICP-MS) and advanced tensor decomposition algorithms with state-of-the-art deep learning procedures was applied for the classification of Croatian continental sparkling wines by their geographical origin. It has ...
In this work, we focused on Wadsley–Roth phase TiNb2O7with an octahedral network as a negative electrode material for lithium-ion batteries and investigated the effect of the network structure, which is considered to form Li+conduction pathways, on the electrode properties. To this end, we pr...
it would lead to an increase in OH removal due to the reaction of OH and NO2. Herein, to evaluate the effect of HAM on radical chemistry, we utilized the OH recycling probability, calculated from primary OH formation and OH recycling, to reflect the stability of tropospheric hydroxyl chemistr...
We will propose NoS sequences with an explicit approach through controversial moments of the acid-base historical development for both lower secondary school and upper or university levels; 2. We will transform a hands-on activity (using cabbage as an indicator) into an inquiry for lower seconda...
The format focuses on using arrays to store information about atoms, bonds, etc—such as the atomic number, bond order, etc. The 3D coordinates are in an array, and each 3D position is offset by 3N where N is the index of the atom. This offers compact, simple representations with effici...
Natural fatty acids, both saturated and unsaturated, are straight-chain compounds with an even number of carbon atoms. 2. Unsaturated acids are often olefinic and have thecisconfiguration. 3. Polyunsaturated acids generally have a methylene-interrupted arrangement ofcis-olefinic double bonds, such as...
Suppressing Jahn-Teller distortion of MnO2via B-Ni dual single-atoms integration for methane catalytic combustion Manganese oxides typically undergo irreversible phase transformations during redox reactions due to the Jahn-Teller effect. This study introduces adjacent B-Ni single-atomic sites as an electro...
The molecular descriptors used to predict the BALB/3T3 𝐼𝐶50IC50 (nM) values are as follows: AMID_O (averaged molecular ID on O atoms), EState_VSA5 (EState VSA Descriptor 5 (1.17 ≤ x < 1.54)), GATS2c (Geary coefficient of lag 2 weighted by Gasteiger charge), MDEO-12 (molecula...
