N-95 masks

N-95 masks Context The Government has notified N-95 Masks as an essential commodity under Essential Commodities Act, 1955 . Thus, hoarding, black-marketing of the essential commodity is punishable offence under the Act. To keep check on the hoarding, black-marketing of the essential commodity, NPPA in exercise of the powers conferred under National Disaster Management Act, 2005 had directed all States/ UT Governments to ensure sufficient availability of surgical and protective Mask

Nanomicelles: using nanoparticles for cancer treatment

Nanomicelles: using nanoparticles for cancer treatment Context: GS Paper III S&T Nanotechnology (PT-Mains-Essay) With the advance in nanotechnology, researchers across the globe have been exploring how to use nanoparticles for efficient drug delivery. Similar to nanoshells and nanovesicles, nanomicelles are extremely small structures and have been noted as an emerging platform in targeted therapy. Nanomicelles are globelike structures with a hydrophilic outer shell and

Particle physics- Large Hadron Collider experiment

Particle physics- Large Hadron Collider experiment Introduction On March 23, a wave of excitement propagated through the particle physics community when researchers from the LHCb experiment at CERN, situated in the Franco-Swiss border, announced the results of their latest analysis of data. Verge of discovery While the findings were not sufficiently strong to be counted as a discovery, CERN scientists were excited enough to reveal that if the anomaly they had detected was con

Nanotechnology in India

Nanotechnology in India What is Nano Technology? Nanotechnology in India is the development and use of techniques to study physical phenomena and develop new devices and material structures in the physical size range of 1-100 nanometres (nm), where 1 nanometre is equal to one billionth or 10^−9 of a meter. Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale with at least one dimension sized from 1 to 100 nanometers. On

Nanomaterials' role in resolving environmental problem

Nanomaterials' role in resolving environmental problems The application of contemporary technology, such as nanomaterials or Carbon Dots (CD), may provide remedies for environmental problems like water contamination. The integrity of the aquatic environment has been harmed by the entry of poisonous and hazardous contaminants into waterbodies as a result of modern society's urbanisation. New technological advancements like nanotechnology offer creative answers for effective and

Proton Beam Therapy

Proton Beam Therapy Proton beam therapy (PBT) is difficult for cancer patients in India to access due to a lack of facilities and its high cost, which can reach run into tens of lakhs of rupees. In India, there aren't any public facilities that provide proton beam therapy treatment at the moment. For treating solid tumours, particularly head and neck cancers, the procedure is regarded as an effective substitute for radiation therapy. What is Proton Beam Therapy? It is

Nano Drones

The emergence of Nano and micro drones and compact unmanned aerial vehicles (UAVs) with advanced capabilities, introduce fresh security challenges. Drone- It means an aircraft that can operate autonomously or remotely without a pilot on board.India reported 79 cases of using drones for weapon delivery 2020, 109 in 2021 and 266 in 2022. Provisions under Drone (Amendment) Rules 2022 Criteria- To operate a drone legally, the criteria set by the Civil Aviation Ministry and

Fibre Optic Network

During the unprecedented COVID-19 pandemic, the one thing that connected us virtually was high-speed internet connections through the fibre optic network. Optical fibres – They are thin cylindrical strands of glass whose diameter is close to the diameter of a human hair. They are surrounded by protectives to make them strong, light, and flexible and thus durable. It can carry information like text, images, voices, telephone calls across large distanc
