Abstract Hydrogels are heavily‐hydrated 3D microliths having loose, porous structures. Unlike organogels, elastomers, and carbohydrates, hydrogels structures with water as a continuous phase/solvent. Being water‐based, they provide lot of scope for facile improvizations in their structure introducing chemical functionalities. They can house various functional materials highly networks, making them potential candidates diverse applications. Various possibilities using different starting...
Sulfonated MoO3–ZrO2 binary oxides (MZS) with different Mo/Zr ratios were synthesized and applied as bifunctional catalysts for the simple one-pot transformation of fructose to 2,5-diformylfuran (DFF). The presence Brønsted acid sites molybdenum oxide species in is responsible high efficiency good activity catalysts. former contributes a yield 5-hydroxymethylfurfural (HMF) dehydration, latter has role catalyzing selective aerobic oxidation resulted HMF into DFF. In optimized reaction...
A series of protonated molybdenum trioxide and nitrogen-doped carbon (Mo-HNC) were prepared through a facile method applied as bifunctional catalyst for the direct synthesis 2,5-diformylfuran (DFF) from fructose. The loading amount is key factor either or catalytic performance in fructose to DFF transformation. Higher MoO3 contributes higher surface area, area will turn promote protonation process, resulting acid density catalysts. catalysts showed good activity both dehydration HMF aerobic...
Abstract The conversion of fructose into 2,5‐diformylfuran (DFF) is a tandem reaction that consists the dehydration to 5‐hydroxymethylfurfural (HMF) catalyzed by an acid catalyst and subsequent oxidation HMF DFF redox catalyst. Phosphomolybdic encapsulated in MIL‐101 (PMA–MIL‐101), with high Brønsted acidity moderate potential, was evaluated as promising for one‐pot synthesis directly from fructose. results demonstrated PMA–MIL‐101 efficient recyclable bifunctional production DMSO; it showed...
Low-cost pyrolysis units such as flame curtain kilns are gaining popularity for biochar production. However, the processes that govern working of not well understood. Here, emissions, temperatures and mass loss monitored in real-time during kiln operation, followed by extensive sampling. We found adjusting layering rates feedstock we can obtain a yield (28 wt% with fixed carbon content 65 wt%) comparable to produced from same continuous-scale unit, highlighting importance systematic...
Abstract The present study is focused on the production of a biosurfactant using Yarrowia lipolytica MTCC 9520 by employing inexpensive lipid waste, chicken tallow from slaughterhouses. Plackett–Burman and Box–Behnken Design analyses were adopted for preliminary screening medium variables further optimization. maximal yield 4.4 g L −1 was obtained optimized medium. highest emulsification activity found to be 55%, surface tension decreased 37 mN m at end 96 h. critical micelle concentration...
As a natural polymer, cellulose is abundant, low-cost, robust, and biodegradable can be chemically modified. This work explores the enhancement of mechanical, thermal, flexoelectric properties three-dimensional (3D)-printed carboxymethyl (CMC) due to addition mechanically exfoliated hexagonal boron nitride (hBN). hBN was observed act as rheology modifier, CMC reinforced with 2% exhibited maximum apparent viscosity 12.24 Pa·s at shear rate 100 s–1. The 0.5% hBN/CMC film highest mechanical...
This paper shows how non-layered naturally occurring tourmaline silicates can be exfoliated into 2D structures for use in fabrics and 3D printed biomedical health monitoring devices.
Climate change and high eutrophication levels of freshwater sources are increasing the occurrence intensity toxic cyanobacterial blooms in drinking water supplies. Conventional treatment struggles to eliminate cyanobacteria/cyanotoxins, expensive tertiary treatments needed. To address this, we have designed a sustainable, nature-based solution using biochar derived from waste coconut shells. This provides low-cost porous support for immobilizing microbial communities, forming biologically...
Abstract In this study, Fe doped, Co and CoO encapsulated N doped carbon frameworks were prepared from simple hybrid zeolite imidazole (ZIF) with extra enrichment. The facile strategy included preparation of ZIF‐8 core ZIF‐67 shell later replacing the metal centers ZIF ions increasing content rich melamine. oxide components got captured in mesoporous through a pyrolysis process at different temperatures. Fe, trapped networks annealing denoted as FCNCx. activity electrochemical stability such...
