Reply by the Central Pollution Control Board (CPCB) in compliance to the National Green Tribunal (NGT) order dated January 21, 2024 in the matter of ‘News item titled “Feeling anxious? Toxic air could be to blame” appearing in Times of India dated 10.10.2023’. NGT had directed CPCB to file a …
The nascent field of nanotechnology-enabled metallurgy has great potential. However, the role of eutectic alloys and the nature of alloy solidification in this field are still largely unknown. To demonstrate one of the promises of liquid metals in the field, we explore a model system of catalytically active Bi-Sn nano-alloys …
2.78 million workers die from occupational accidents and work-related diseases each year warns this new report released by International Labour Organisation (ILO). It attributes stress, excessively-long working hours and disease to worker casualties every year. According to recent estimates released by the International Labour Organization (ILO), each year 2.78 million …
Bacterial drug resistance has emerged as a serious global threat mandating the development of novel methodologies that allow facile modulation of antimicrobial action in a controlled fashion. Conjugating antibiotics to nanoparticles helps to meet this goal by increasing the drug’s overall avidity, bioavailability and easier internalisation into mammalian cells, targeting …
Reduced graphene oxide (rGO) is a promising antibacterial material, the efficacy of which can be further enhanced by the addition of silver nanoparticles (nAg). In this study, the mechanisms of antibacterial activity of rGO–nAg nanocomposite against several important human pathogenic multidrug resistant bacteria, namely Gram-positive coccal Staphylococcus aureus and Gram-negative …
A rich literature exists that has demonstrated adverse human health effects following exposure to ambient air particulate matter (PM), with strong support for an important role for ultrafine (nano-sized) particles. At present, relatively little human health or epidemiology data exists for engineered nanomaterials (NM) despite clear parallels in their physicochemical …
Energy harvesting performance of an efficient flexible bio-piezoelectric nanogenerator (BPNG) is demonstrated, where “bio-waste” transparent fish scale (FSC), composed of self-assembled and ordered collagen nano-fibrils, serves as a self-poled piezoelectric active component, exhibiting intrinsic piezoelectric strength of −−5.0 pC/N. The dipolar orientation (∼19%) of the self-polarized FSC collagen is confirmed …
A team of researchers from Institut Teknologi Maju (ITMA), Universiti Putra Malaysia (UPM) has succeeded in inventing a new system, known as Nanotechnology for Encapsulation of Phase Change Material (NPCM) that can bring down room temperature in buildings, thus minimising the use of air-conditioning or heating systems, and saving electricity …
Incredible scientific discoveries happen all the time when researchers haven't been looking for them, and new nanorods that harvest water from the air are no exception. These unintentionally produced carbon-rich microscopic stalks absorb and release water differently to every other material we know about. They can absorb more water at …
Antibiotics have been considered emerging pollutants due to their continuous input and persistence in the aquatic ecosystem. The present paper addresses the degradation and removal processes applied to a specific class of micropollutants, the antibiotic tetracycline (TETRA). Photocatalytic degradation of tetracycline in aqueous suspensions of titanium dioxide in the presence …
The National Mission on Himalayan Studies (NMHS), G. B. Pant Institute of Himalayan Environment and Development (GBPIHED) under the ministry of environment, forest and climate change has approved, Kumaun University's project titled, "Environmentally Sustainable Smart Synthesis of Carbon Nano material along with the production of High Value Added Fuel and …
A nanocapsule that dissolves blood clots very fast and can be administered without specialised equipment promises to be the next revolution in treatment of heart attacks and strokes, says a study. The capsule with the drug can be administered by paramedics in emergency situations saving much time. It acts within …
The Science & Technology Department of Gujarat Government has initiated an exercise to frame integrated policy for Nano Technology policy in lines with the Information Technology and Electronics Policy. In the late 1990s, Gujarat Government missed the bus to attract investments in IT sector. The present State Government seems to …
Little information is available regarding the suitability of analytical methods to evaluate claims regarding the presence of engineered nanomaterials (NMs) in consumer products, their potential toxic effects to humans, or their life cycle after product use. This study was designed to assess the potential interactions across the life cycle of …
As India nears the end of its mammoth general-election process, research advocates warn that whichever party wins, the government must do more than pay lip service to science.
Vernon Hugh Bowman, a 75-year old Indiana farmer, says that switching to Monsanto Inc.'s "Roundup Ready" soybeans "made things so much simpler and better." Monsanto's patented beans can survive when they are sprayed with the herbicide glyphosate, also known as Roundup, which makes pest control much easier. Monsanto is less …
A US scientist has invented a new kind of light bulb that uses plastic polymers and nano materials to generate light that is more energy-efficient than current fluorescent lights and is easier on the eye. Details of the new invention were published Monday on the website of Wake Forest University …
Photodegradation is one of the advanced oxidation processes rather than other treatments and it is most effective for the removal of organic pollutants. ZnO is an excellent photocatalytic oxidation material. In the present study nanosized ZnO has prepared by coprecipitation technique under different experimental conditions and employed in the removal …
Based on previously published hydroponic plant, planktonic bacterial, and soil microbial community research, manufactured nanomaterial (MNM) environmental buildup could profoundly alter soil-based food crop quality and yield. However, thus far, no single study has at once examined the full implications, as no studies have involved growing plants to full maturity …
Nanotechnology, which is fast emerging as the future science promising thousand things including cures for complicated diseases, could prove to be toxic for human beings, animals and environment. Nanoparticles are extremely miniscule and this makes them potential agents of toxicity in humans during drug delivery. Their infinite smallness enables them …
The increasing industrial application of metal oxide Engineered Nano-Particles (ENPs) is likely to increase their environmental release to soils. While the potential of metal oxide ENPs as environmental toxicants has been shown, lack of suitable control treatments have compromised the power of many previous assessments. We evaluated the ecotoxicity of …
