TL;DR: In this article, a study using supercritical CO2 as a replacement working fluid was conducted to evaluate the potential benefits and drawbacks compared with water as a fracturing fluid; it may increase gas production through several coupled processes including enhanced fracturing, reduced flow blocking, and miscibility with in-place hydrocarbons.

TL;DR: The parameter J0, commonly used in solar cell modelling, has a deep physical meaning, which is intended to clarify by recommending that J0 be referred to as a recombination parameter.

TL;DR: In this paper, nanostructured graphite oxide, silica/graphite oxide composites and silica nanoparticles were used for the removal of the heavy metal ions from aqueous solutions by a batch adsorption method and have been modelled using classical Langmuir and Freundlich adsorization isotherms.

TL;DR: The second generation biodiesel includes non-edible vegetable oils, waste cooking oils as well as animal fats as mentioned in this paper, which are considered as promising substitute for traditional edible food crops as they neither compete with food crops nor lead to land clearing.

TL;DR: In this paper, the effect of polypropylene/poly(lactic acid) weight ratios on the properties of blend films compatilized with poly-propylene-grafted-maleic anhydride were investigated with 100:0, 60:40, 50:50, 40:60, and 0:100 of weight ratio.

TL;DR: In this article, the authors report a critical analysis of some studies that investigate shading devices' effects on building thermal and/or lighting performances and point out the difficulty in comparing the different results given the lack of uniformity between the studies, since they analysed buildings with different characteristics, locations and using various indices.
