Formulation of Polymer-Augmented Surfactant-Based Oil-Water Microemulsions for Application in Enhanced Oil Recovery.

This research explores the development of engineered oil-water microemulsions stabilized by a synergistic combination of polymer and surfactant to enhance stability and interfacial properties for improved enhanced oil recovery (EOR). Conventional surfactant-stabilized emulsions often suffer from phase instability and limited wettability alteration during water flooding and chemical injection, hindering the EOR efficiency. In contrast, our formulations incorporating polymers significantly increase the emulsion viscosity and resilience to temperature fluctuations, resulting in enhanced phase stability.

Study of multimodal light emissions from Pr/Yb doped NaLa(MoO) phosphors for optoelectronic devices and plant-growth applications.

Recent advancements in materials design have driven the scientific community to explore phosphor materials for multifunctional applications. This study presents the multimodal light emission (downshifting - DS, quantum cutting - QC, and upconversion - UC) from Pr/Yb activated NaLa(MoO) phosphors for multifunctional applications. Under blue (449 nm) and NIR (980 nm) excitation, co-doped phosphors emit visible light through DS and UC processes caused by different f-f transitions of Pr ions.

An improved class of predictive estimators of population distribution function in the presence of non-response.

In the present work, we have proposed a novel general class of estimators for the estimation of population distribution function in two distinct situations of non-response. The estimation of distribution function (DF) may play an important role in environmental sciences such as in modelling the annual data of atmospheric NOx temporal concentration, drug removal rates from the body, to present the distribution of gene expression levels across cells etc. Similarly, it may also be useful in other environmental data like groundwater quality, rainfall, wind speed, river discharges, etc.

Comprehensive review of the monitoring and sensing system in slopes with a special focus on the mining sector.

The failure of slopes due to various natural processes or extensive mining activities is a common problem that has an adverse impact on the environment and may result in severe casualties. Despite taking all the geotechnical considerations for the safe design of slopes, there could be unpredictable slope failure because of unexpected weather, seismic activities, or involvement of unidentified geological structures. Thus, continuous monitoring, forecasting, and warning of slope failures are imperative to save lives and property from devastation.

Vibrational spectra of serotonin by terahertz time domain spectroscopy and DFT simulations.

These bands are originated from G→H, G→F, and F→H transitions of the Tm ion, respectively.

Harnessing Ruthenium and Copper Catalysts for Formate Dehydrogenase Reactions.

Formic acid (HCOOH) is a promising source of hydrogen energy that can be used to produce hydrogen in a more economical and ecological way. Formic acid is a simple carboxylic acid with a high hydrogen concentration and is generally stable, making it useful as a hydrogen transporter. Catalytic dehydrogenation is usually used to extract hydrogen from formic acid; this process releases hydrogen gas and yields carbon dioxide as a byproduct.

Assessment of dew harvesting as a sustainable water source and air quality indicator: a case study of Dhanbad, Jharkhand, India.

Dew formation takes place when atmospheric water vapor condenses on the surface which cools down due to radiation deficit. As it is a local phenomenon, its study gives information about the pollutants present in the atmosphere. Also, since dew formation is a natural phenomenon, and involves passive cooling, this can be a potential method for atmospheric water harvesting.
