TL;DR: In this paper, mass transfer kinetic approach has been successfully applied for the determination of various parameters necessary for designing a fixed-bed absorber, such as the length of the (PAZ) primary adsorption zone, total time involved for the establishment of primary adaption zone (tx), mass rate of flow to the absorber (Fm), time for primary adsoration zone to move down its length (tδ), amount of adsorbate adsorbed in PAZ from breakpoint to exhaustion (Ms), fractional capacity (f), time of initial

TL;DR: Evaluation of OpenAI's GPT models, Google-internal dense transformer architectures, and Switch-style sparse transformers on BIG-bench, across model sizes spanning millions to hundreds of billions of parameters finds that model performance and calibration both improve with scale, but are poor in absolute terms.

TL;DR: The proposed sensor exhibits very good selectivity for Zn(2+) over other cations and can be used in a wide pH range and has also been possible to use this assembly as an indicator electrode in potentiometric titrations involving zinc ions.

TL;DR: In this article, the effect of pH, temperature, initial absorbate concentration, particle size of the adsorbent and solid to liquid ratio on the kinetics of adsorption was delineated.

TL;DR: In this article, a polyvinyl chloride (PVC)-based membrane of 15-crown-5 exhibits a good response for lead(II) ions over a wide concentration range.
