Although CMF and CNF have been successfully obtained from the mentioned technologies, several drawbacks still exist such as high energy consumption and chemical agents required. Refining has been widely used as pretreatment combined with other defibrillation treatments such as homogenization to obtain CMF/...
The mechanical strain energy associated with these deformations is included in the Helmholtz free energy, along with the chemical and interfacial energy, to describe diffusion and reaction. The oxidation rate is expressed as a function of chemical potentials of reactants and products leading to a ...
近日,康奈尔大学Robert F. Shepherd等人将研究自然中的系统集成和多功能性如何激发自主机器人的新范式,即所谓的“具身能源(Embodied Energy)”。大多数不受束缚的机器人使用电池来储存能量并为其操作提供动力,而最近能源储存技术的进步使得化学或电力能源可以直接嵌入用于制造机器人的结构和材料中,而不需要单独的电池组。
Chemical energy All organisms must work to live, and they require a source of potential energy which can be utilized in order to perform the life processes. This energy can be found in the form of the chemical energy of biomass used as food. Energy can also be in the form of the chemic...
In the production of medical devices or components of titanium, the material - usually a rod or sheet - is first shaped into the geometrical shape of the product. The shape is of course determined by the intended use and function of the component or devi
The carbonation process is directly related to Gibbs free energy. Low energy values result in deep carbonation. Energy values increase as the Ca/Si ratio decreases. High production of C–S–H results in low Ca(OH)2 quantity, which increases the chemical resistance of the paste (Duguid et al...

By coupling to electrons in the quantum Hall regime, the mechanical response of graphene resonators is modulated by changes in the chemical potential. The classical picture of the force on a capacitor assumes a large density of electronic states, such th
