surface morphology and roughness of the films was observed by field emission scanning electron microscopy (FE-SEM, Model: JSM-6701F) and atomic force microscopy (AFM, Digital Instrument, nanoscope III) operated at room temperature, respectively. The electrical properties of the films were determined using Hall measurement system (Van der Pauwconfiguration, Hilton, Australia) at room temperature.

For analysis of the sensing properties, analyze the morphology of the sample with AFM. As analyzing its electrical properties, measure time-variant IV shifting curve fo

properties we wish to have in any drug delivery across the BBB(Blood brain barrier). In this context, owing to their small size, customizable surface, improved solubility, targeted drug delivery and multifunctionality, nanoparticles have emerged as potential drug delivery carriers to tissues throughout the body. Yet passing the BBB is particularly difficult. The proper design of such engineered
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for
