However, the small incisions required for MIS inhibit maneuverability and access to the surgical site. Dexterous robotic instruments are a promising area of research to overcome these challenges in MIS. Tendon-driven continuum robots have shown potential to expand surgeon capabilities for operating within confined spaces and with minimal injury to the patient. For many procedures, miniaturized devices on the micro- and meso-scale are desired to access confined areas within the body and enable sufficient maneuverability. These robots are a topic of active research, and the fabrication of such miniaturized mechanisms remains challenging. To address these challenges, this paper provides a tutorial which outlines and evaluates various methods for attaching tendons in micro-and meso-scale robotic joints. Attachment techniques including bonding and plate mechanisms are used to assemble nitinol and tungsten tendons within both micro- and meso-scale samples. For micro-scale robots, samples less than 1 mm in diameter are used to evaluate the strength, repeatability, and actuation within a continuum robotic guidewire. For meso-scale robots, such as 1.93 mm diameter neuroendoscope tools, tendon placement is achieved using stainless steel and 3D-printed plates. Furthermore, the effects of solder and epoxy knot reinforcement are studied. Detailed procedures for attachment methods are provided, and the strengths and limitations of the tendon materials and attachment methods studied in this paper are highlighted for specific applications.</p></div>","PeriodicalId":675,"journal":{"name":"Journal of the Indian Institute of Science","volume":"104 3","pages":"623 - 643"},"PeriodicalIF":1.8,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In India, industrialization and urbanization also significantly release these contaminants, exacerbating environmental pollution and posing risks to human health and ecosystems. Global emerging pollutants are increasingly concerning due to their persistence and potential adverse impacts. Understanding the toxicity and fate of these substances is essential for developing effective remediation strategies, given their complex transformations in environmental contexts. Remediation is challenging because contaminants possess varied characteristics and are widely dispersed, but innovative technologies like advanced oxidation processes, phytoremediation, and membrane filtration offer promising solutions. Sensor-based detection methods, including biosensors and nanomaterial-based sensors, are vital for real-time monitoring, aiding in risk assessment and environmental management.

The aim of this paper is to explore the potential of plastic waste as a material resource, and thermocatalytic pyrolysis as a recycling process, to produce aliphatic and aromatic hydrocarbons, which are important chemical intermediates for various industries. We show that plastic pyrolysis can achieve a high yield of liquid hydrocarbons (~ 80%) with a suitable distribution of aliphatic and aromatic compounds, by using different pyrolysis conditions and a catalyst. Specifically, this paper demonstrates the possibility of deriving two key classes of hydrocarbons, i.e., aliphatic (C10–C20 hydrocarbons) and aromatic hydrocarbons (xylene, toluene and benzene derivatives) with a yield of ~ 80% liquid hydrocarbons via catalytic pyrolysis. We also briefly discuss the challenges and opportunities, and the environmental and economic implications.</p></div>","PeriodicalId":675,"journal":{"name":"Journal of the Indian Institute of Science","volume":"104 2","pages":"383 - 394"},"PeriodicalIF":1.8,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142889980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to globalization, these fragile ecosystems are vulnerable to unplanned developmental activities and rapid urbanization, leading to large-scale land cover changes and hydrologic regimes. The sustained inflow of untreated wastewater (from the industrial and domestic sectors) into wetlands has altered the chemical integrity, which necessitates inventorying, mapping, and regular wetland monitoring to evolve conservation strategies. Integrating spatial and non-spatial data, analysis, and visualization with decision models through decision support systems enables informed decisions.

Rapid large-scale land use changes have resulted in an alteration in the hydrologic regime, the loss of habitats, and the disappearance of native species.
