Abstract
SnO2 nanoparticles were produced in aqueous solution utilizing green method without the need of any templates, catalysts, or organic reagents in this study. Powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), high-resolution TEM (HRTEM), Fourier transform infrared (FT-IR) spectroscopy measurements were used to characterize the as-prepared SnO2 nanoparticles. Microwave irradiation can create SnO2 with a consistent size and shape, as well as a high crystallinity. A probable production mechanism of SnO2 nanoparticles was hypothesized based on experimental results. Furthermore, environmental catalytic performance of the obtained SnO2 nanoparticles in the degradation of Rhodamine B (RhB) in aqueous solution was discovered, showing that these SnO2 nanoparticles are very promising for wastewater treatment.

Abstract
In this study, Bi/TiO2 was successfully synthesized by simple and cost-effective precipitation method. Titania has drawn increasing attention among diverse oxide photocatalysts due to its biological and chemical inertness, strong photo oxidization power, cost effectiveness, and long-term stability against light and chemical corrosion The composite Bi/TiO2 was characterized by means of scanning electron microscopy (SEM) with elementary dispersive X-ray analysis (EDX) and X-ray diffraction (XRD) analysis. It's crucial and difficult to find anatase TiO2 with high thermal stability and photocatalytic activity. Heat treatment, on the other hand, affects photocatalytic activity by changing the textural properties, crystallinity degree, and surface chemical states. The great thermal stability of the as-prepared TiO2 nanosheets is due to high crystallization (low impurity) and oxygen vacancy. Surprisingly, high photocatalytic activity for photocatalytic oxidation breakdown of acetone in air under UV light illumination.

Abstract
The incorporation of electronics by embedding the relevant sensors in the physical devices in home and office, vehicles of all types, buildings in the smart cities and in all possible spheres of life form a network of devices termed as internet of things (IoT). It is being realized that vehicular ad-hoc networks (VANETs) which are responsible for the reliable and secure communication among vehicles is a primary area of research in IoT and hence ensuring security in this area is essential. Thus, this work introduces a novel approach to improve the existing authentication support to VANETs. In this proposed framework, first an anonymous authentication approach for preserving the privacy is proposed which not only performs the vehicle user’s anonymous authentication but preserves the message integrity of the transmitting messages as well. Although many anonymous authentication schemes have been proposed in VANETs until now, the existing schemes suffer from a high computation cost during the signature and certificate verification process which leads to delayed authentication. Consequently, the vehicles and roadside units (RSUs) cannot authenticate more number of vehicles per second in VANETs. Second, an efficient anonymous group key distribution protocol is proposed in this paper for securely distributing the group key to the group of vehicles in the communication range of an RSU. The RSUs can send location-based information to the group of vehicles in a secure manner using this group key. Experimental analysis portrays that the results of this new privacy preserving anonymous authentication and key management schemes are promising and efficient with regard to signature verification cost and computational cost in comparison with the existing schemes.

Abstract
Medicines are an important part of modern health care system. The market for pharmaceutical medicines runs in billions of dollars a year. But recently a new problematic phenomenon has risen which is termed as “Poor Medication Adherence”. In simple terms it refers to improper intake of medicines as prescribed by doctor. Study shows that the reason for it is forgetfulness. So, the instrument devised here is to address the problem by building a wearable noninvasive device which can alert the patient in time. Since the device is in its initial stage so it was built for only glucose detection to control insulin intake by diabetic patients. Near Infra-Red light when passes through a tissue its absorbance is changed due to interaction with glucose molecules present. By detecting the level of glucose one can determine the insulin requirement of the patient. Glucose is one of the important biochemical produced in the process of metabolism in human body. But also, a proper level of glucose amount will ensure the health of a human. Insulin regulates the amount of glucose level to be maintained in the human body.

Abstract
Diabetes mellitus commonly known as diabetes is a group of metabolic disorders characterized by high blood sugar level over a prolonged period of time. Diabetes can cause many health problems and complications. To overcome this problem, we are going to design a device which we take. The main objective of this device is to make easy for the diabetic patients to check their glucose level in the food without any risk. In this device two types of sensors are used one is temperature sensor and the other one is pH sensor and an Arduino Uno microcontroller is also used which reads the inputs-light on sensors. This device is going to be like a wrist watch. Initially a strip is dipped in the sugar solution or glucose water then the same strip is inserted in the device, then this device shows the amount of sugar or glucose present in your food in the LCD display. In this way whenever the sugar content increase or decrease in your food then the device gives you a warning sound with the help of the buzzer fixed in the device. This device is portable, cost effective and durable and it is very easy to use. In this way a non- invasive food glucose monitor is designed.

Abstract
Technological innovations in the field of disease prevention and patient health have contributed to the development of areas such as the surveillance system. Heart rate is an important health parameter that is directly related to the sound of the human cardiovascular system. The heart rate reflects various physiological conditions, such as the number of heart beats per minute, biological workload, stress at work, and concentration on tasks, drowsiness and active state of the autonomic nervous system. It can be measured by ECG waveform or by pulse sensing - rhythm expansion and contraction through the artery in the form of blood through the normal contraction of the heart. The pulse can be felt from areas close to the arterial skin. This paper describes a technique for measuring heart rate through fingerprint and arduino. It is based on the core of photopeltismography (PPG), an invasive method for measuring blood volume variability in tissues using a light source and detector. When the heart is beating, it actually pumps blood throughout the body and also changes the amount of blood inside the finger artery. These fluctuations of blood can be detected by the optical sensing mechanism placed around the fingers. The signal can be extended and sent to Arduino with the help of serial port communication. With the help of processing software heartrate monitoring and counting is performed.

Abstract
Use of clustering in the field of Sensor Networks can be divided into two ways; one is leaf nodes and the other is to manage this leaf nodes i.e., the Cluster Head (CH). All the leaf nodes are controlled by the CH and the Base Station (BS) takes control of the CH. The duty of the leaf nodes is to sense the data and cannot directly communicate with the BS. On receiving the data, the sensed data is transmitted to the CHs. On receiving the data; CH will perform various data aggregation and fusion techniques and finally transmit it to the base station. Hence the architectural organization of CH should be designed in a way that CH is nearer to the base station. This leads to more energy consumption at CH level and hence, the target is to select the maximum energy node as CH, as failure of CH will lead to total collapse of the entire network. Clustering reduces energy consumption and the number of messages transmitted towards the base station. The main objective of clustering in Wireless Sensor nodes is to extend the network lifetime, as these nodes may carry some sensitive information to fulfil its application specific requirements.

Abstract
In recent years, there is a need for the development of easy, inexpensive, and fast detection methods for the monitoring of environmental pollutions, such as organic, inorganic, and pathogenic pollutants. Recognizing the pollutants that cause environmental pollution is vital in some emergency situations. For this reason, the need for devices with fast and easy detection capability is increasing. In addition, in practical applications, the freely dispersed molecules in the sample to be analysed are far from plasmonically sensitive surfaces. Therefore, plasmonic nanosensors are important and promising devices in that they combine uniquely different features such as inexpensive, high sensitivity, specificity, label-free, and quantitative detection. In this review, the plasmonic nanosensor principle and plasmonic nanosensors for the analysis of environmental pollutants are comprehensively discussed.

Abstract
Copper aluminate nanoparticles (CuAl2O4 NPs) were synthesized successfully by a simple green route using Z. officinale extract. The Zingiber officinale (Z. officinale) plant is one of the well-known medicinal plants. CuAl2O4 NPs are known to be one of the multifunctional applications. The surface morphology and crystal structure of the synthesized CuAl2O4 NPs were characterized by powder XRD, FT-IR spectroscopy, SEM, TEM, and SAED analysis. The magnetic properties of the CuAl2O4 NPs were analyzed by VSM technique. The formation of cubic spinel structure CuAl2O4 NPs was confirmed by powder XRD. The average crystallite size of CuAl2O4 NPs was measured by sherrer formula and found to be 18.65 nm. The VSM results shows that spinel CuAl2O4 NPs are in magnetic nature.
