Considering the worldwide demand for colorants of natural origin, the utilization of ascomycete fungi as a prolific pigment producer unfolds a novel way to obtain these pigments for various applications, including food, cosmetic, and medical use. The presence of very few natural red pigment alternatives in the market also attracts research and industry priorities to unearth novel and sustainable red pigment producers. The present work is an attempt to identify a novel source of red color obtained from endophytic fungi isolated from terrestrial and marine habitats.

Air pollution is an important issue, especially in megacities across the world. There are emission sources within and also in the regions around these cities, which cause fluctuations in air quality based on prevailing meteorological conditions. Short term air quality forecasting is used not to just possibly mitigate forthcoming high air pollution episodes, but also to plan for reduced exposures of residents.
Nanoscale 2D semi-conductors – Impact of structural properties on light propagation depth and photocatalytic performance
Kumari Priyanka, Bahadur Nupur, O'Dell Luke A, Kong Lingxue, Sadak Abu, Merenda Andrea, Dumée Ludovic F
| 2021
The performance of photocatalytic materials are largely dictated by the crystalline and optical properties of the semi-conductors. The density of photo-generated electron and hole pairs is greatly influenced by the light penetration in photocatalytic material, leading to specific degradation kinetics. In this work, the relationship between the metal oxide film thickness and the overall materials optical and photocatalytic performances are systematically established for the first time.
Novel pilot scale photocatalytic treatment of textile & dyeing industry wastewater to achieve process water quality and enabling zero liquid discharge
Nupur Bahadur, Bhargava Nipun
| 2019
This paper presents a novel end-to-end pilot scale photocatalytic treatment of real textile & dyeing industry effluent, which involved innovative approach in primary treatment, followed by Heterogenous Photocatalysis (HP) involving nano-TiO2/UV as secondary treatment and suitable filtration leading to treated water meeting process water quality enhancing water re-use efficiency. This enables Zero Liquid Discharge (ZLD); which is the need of the hour in tackling problems of po.int source pollution and Water Conservation in developing countries like India.

Surfactant-modified titania for cadmium removal and textile effluent treatment together being environmentally safe for seed germination and growth of Vigna radiata
Das Paromita, Bahadur Nupur, Dhawan Vibha
| 2019
The present work describes synthesis, detailed characterization, and application of bare and surfactant-modified titania nanomaterials (NMs) for various wastewater treatment applications as individual cases like cadmium (Cd) removal, methylene blue (MB) dye degradation, and treatment of real textile and dyeing industry effluent. These NMs are used as adsorbents and photocatalysts in an indegenously developed end-to-end treatment process and a photocatalytic reactor for treatment of textile wastewater.

TERI (The Energy and Resources Institute) has recently developed a novel wastewater treatment technology called TERI Advanced Oxidation Technology (TADOX), which provides an end-to-end treatment of textile and dyeing industry wastewater within a few hours without any kind of bioremediation in the treatment trail. It involves UV/n-TiO2 Photocatalysis during secondary treatment; Photocatalysis, is a promising approach for treating difficult wastewater, however there is always effort to reduce cost and electrical energy consumption.
