Nanotechnology 2023 | September 25-27
My dear friends of eminence and devotee of science and technology, it’s my great honor and pleasure to welcome you through this special note offered by the organizers of this mega event. There is a strong interest and need in the engineering of synthesis of hybrid nanomaterials having wide band gaps, for the various applications of Laymen at very low cost. Hybrid nanomaterials can be utilized extensively in the fields of sensors, power sectors, medicine, disease diagnosis, agriculture, etc. With a special reference, sensors are utilized for security, safety, food freshness, light detection and ranging, disease diagnosis, monitoring environmental pollution, detection and control of concentration of sprays in agriculture, crop yield, etc. Nowadays, available traditional type semiconducting gas sensors have some problems, viz. limitations of sensing the gases below Threshold Limit Value, high cost, difficulties in availability, etc. Most of the researchers are taking efforts in developing the sensor models. For large applicability to Laymen, features of the sensors must be improved, viz. high response at trace level of the gas (ppm, ppb or even sub-ppb level), quick response-recovery profile, longer life time, long-term stability, high selectivity to a particular gas among the mixture of gases, low cross sensitivity, very specific sensor location judgment, low cost, low power consumption, portable in size, etc. These features mainly depend on and co-related with crystallite size, thickness of sensor, nature of additives and their concentrations, microstructures and nanostructures, temperature, etc.
Also, nowadays, people have very busy schedule and they prefer the foods and junk foods in readily available packets. The packets are not stored as per the directions of food storage technology. As a result, the foods are degraded in somewhat proportions. On consumption of such degraded foods, people may suffer from diarrhoea, indigestion, stomach disorders, vomiting, acidity, headache, body ache, food poisoning, etc. So, it is today’s need to detect the degree of degradation of such readily available foods in the markets.
I am sure that, if the hybrid materials can be tailored in size and shape, it can change all the properties tremendously and may fulfill the needs of society at a very low cost. Wishing you all the best and contribute for the grand success of this mega event. Thanks lot for your precious time.
