“…The peak assignment was done according to the cited literature. 16,[31][32][33] The synthesized IL was characterized by thermogravimetric analyses (TGA/DSC), and the results were compared with the reported data for this IL. It was found that [TMG][HSO 4 ] is stable up to 250 C. The TGA/DSC plot of the ionic liquid is furnished in the ESI (Fig.…”

“…This rough flaky surface allows copper ions to adhere more easily, improving the process of biosorption. The biosorbent's porosity also helps it interact with the adsorbate more quickly 50 . On the other hand, the SEM images after biosorption of copper revealed a flatter biosorbent surface, appearance of discrete lumps and vanishing of big spaces (Fig.…”

In this study, the Rosa damascena leaf powder was evaluated as a biosorbent for copper removal from aqueous solutions. Optimized conditions of 4.0 g/L biosorbent dosage, pH of 5.5 and initial copper concentration of 55 mg/L obtained by Response Surface Methodology were employed for Cu2+ biosorption by R. damascena leaves and up to 88.7 % Cu2+ was removed. The biosorption data were well ﬁtted to the pseudo-second order and Elovich kinetic models. The Langmuir and Dubinin-Radushkevich isotherm models were also best fit the experimental data showing monolayer isotherm with qmax value of 25.13 mg/g obtained at optimum conditions. Thermodynamic parameters showed the spontaneity, feasibility and exothermic nature of adsorption. Scanning electron microscopy, Energy-Dispersive X-Ray, and Fourier transform infrared spectroscopy were used to characterize the biosorbent before and after Cu2+ biosorption, revealing outstanding structural characteristics and high surface functional groups availability. In addition, immobilized R. damascena leaves adsorbed 90.7 % of copper from aqueous solution, which is greater than free biosorbent (85.3 %). It can be concluded that R. damascena might be employed as a low-cost biosorbent for removing heavy metals from aqueous solutions.

“…The most explored gasoline type biofuel derived from this renewable biomass is bioethanol. [5,6] Although it reduces the carbon dioxide emissions, but the downsides for this fuel are its low boiling point, water miscibility and low energy content (6.1 kWhL À 1 ) as compared to 8.8 kWhL À 1 of gasoline. [7,8] In addition, burning ethanol mixtures in car engines causes corrosion, poor engine cold-start performance, production of toxic acetaldehyde [9] and photochemical smog.…”

5-Ethoxymethylfurfural (5-EMF) is a promising fuel alternative and biofuel additive due to its high energy potential. Principal method for its synthesis is etherification of hydroxyl group of 5hydroxymethylfurfural (5-HMF), produced by the dehydration of fructose. Currently existing methods for the synthesis of 5-EMF are not industrially feasible due to the issues associated with their starting materials; either they are highly expensive (such as 5-HMF), or compete with food (sugars such as fructose and glucose). Herein, we are reporting a one-pot protocol for the synthesis of 5-EMF using non-food indigenous agricultural waste material, thus completely eliminating the both issues. Cost is also very much reduced due to the utilization of cheap pyridinium based ionic liquids. Energy, time and solvents use is also reduced, as reaction is happening in a single pot. The process is optimized first for fructose (73 % 5-EMF yield) and glucose (16 % 5-EMF), and was then extended for real biopolymeric cellulose (16 % 5-EMF) and wheat husk biomass (15 % 5-EMF). Product was characterized via HPLC and 1 HNMR spectroscopy.
