Thermoplastic Polymer Compounding with ZnS Nanostructures: Innovations and Applications
Full text linkThis study investigates the compounding of thermoplastic polymers with ZnS nanostructures, focusing on innovative synthesis methods and applications. The principal objective was to enhance the mechanical, thermal, and electrical properties of thermoplastic polymers by incorporating well-characterized ZnS nanoparticles. Utilizing a chemical precipitation method, ZnS nanoparticles with controlled size and high purity were synthesized. Characterization techniques, including XRD, SEM, TEM, EDS, and FTIR, confirmed the crystalline structure and elemental composition of the nanoparticles. Three compounding techniques—melt blending, solution casting, and in-situ polymerization—were explored for integrating ZnS nanoparticles into thermoplastic matrices. Each method was optimized for uniform nanoparticle dispersion and strong interfacial bonding. The findings revealed that nanocomposites produced via these techniques exhibited significantly enhanced tensile strength, impact resistance, thermal stability, and electrical conductivity compared to pure thermoplastics. The study\u27s implications extend to industrial applications in electronics, automotive components, aerospace parts, and advanced packaging materials. The environmental benefits, such as reduced material consumption and improved recyclability, along with potential economic savings, underscore the broader impact of these advanced materials. This research provides a solid foundation for future development of high-performance ZnS-thermoplastic nanocomposites, promoting innovation in material science and industrial applications
The Value of Solar Photovoltaics in an Isolated Competitive Electricity Market: a Case Study of Singapore
Full text linkWith a view of achieving its obligations under the global climate change regime, and low technical potential for other renewable energy technologies, solar photovoltaics (PV) is the main focus for Singapore to generate low carbon electricity. However, a high penetration of PV in Singapore’s electricity market would result in a number of costs and benefits that need to be quantified in order to ensure prudent government policies for “supporting” the widespread adoption of PV in Singapore. The quantification of these costs and benefits would allow policymakers to realize the true “value” of solar PV for Singapore and would address the limitations of relying on the levelised cost of electricity metric. This paper provides an assessment of the societal value that PV would bring to Singapore, essentially an isolated power system with a liberalized electricity market. For the purpose of this study, the determination of the value of solar involves quantifying the savings due to the merit order effect, costs due to additional frequency control services, and net avoidance of CO2 emissions
Reinforcement Learning for Robotic Grasping and Manipulation: A Review
Full text linkA century of robots is the 21st century. The robots have long been able to cross the divide between the virtual universe and the real world. Robotics, as the most successful contender in the upcoming great technological revolution, will play an ever more important role in society because of the impact it has in every field of life, including medicine, healthcare, architecture, manufacturing and food supplies, logistics and transport. This document introduces a modern approach to the grasp of robots, which draws grasp techniques from the human demonstration and combines these strategies into a grasp-planning framework, in order to produce a viable insight into the objective geometry and manipulation tasks of the object. Our study findings show that grasping strategies of the form of grasp and thumbs positioning are not only necessary for human grasp but also significant restrictions on posture and wrist posture which greatly reduce both the robot hand\u27s workplace and the search space for grasp planning. In the simulation and with a true robotic system this method has been extensively tested for several everyday living representative objects. In the experiment with varying degrees of perceiving in certainties, we have demonstrated the power of our method
Performance Evaluation of Single Slope Solar Still by Integrating with Solar Thermal Systems
Full text linkThe world is facing the state of being scarce of fresh or drinking water and it is the major problem and global challenge. Along with air and food, water is a basic necessity for human. Solar energy is the biggest source of energy available on earth. A solar distillation is one of the methods for purifying salt water to drinking water. In this method fresh water is obtained by exposing a small layer of salt water to solar radiation and the water vaporized from the basin is condensed on the bottom side of a taper transparent cover. It can be collected in receiving troughs at the end of the still. For this research, a solar still has been designed, fabricated and tested under the climate condition of Coimbatore (11.01680 N, 76.9550 E), India from December 2016 to March 2017. The still basin area was 1m2 and the glass cover of still is inclined at 13 degree based on the city latitude. Solar still is integrated with thermal system such as solar photovoltaic system and then with solar pond in order to preheat the feed water thereby increasing the productivity considerably. Experiments were carried out on the still using different parameters and tested for performance. The results showed that the daily production of the conventional solar still was 2 Lit/m2/day and integrated with photovoltaic system and solar pond was 3.1 Lit/m2/day and 2.54 Lit/m2/day respectively
Influence of IoT Technology on Environmental Monitoring
Full text linkThe newly connected globe has the potential to become a more environmentally friendly and sustainable place if more efficiencies can be brought to various industries. We will look at examples of how the Internet of Things technology is helping to improve the world. Relatively recently, the technology of the fourth industrial revolution has given rise to the characteristics of things constantly expanding, and everything, including people, things, people, and the environment, is connected based on the Internet. In particular, the network structure is connected to various Internet of Things devices and transitioning from wired to wireless. Gateways both within and outside the smart home can now be used to control other devices, in contrast to users who previously owned each device individually. However, due to these changes, the environment is now susceptible to attacks from the outside. For example, when an attacker gains access to a gateway, he can attempt various attacks, such as port scans, OS and service detection, and denial of service assaults on Internet of Things devices. As a result, the findings of the study reveal the influence of IoT technology, which has the potential to improve environmental monitoring to enhance environmental safety
