Characterization of Whole Biomasses in Pyridine Based Ionic Liquid at Low Temperature by 31P NMR: An Approach to Quantitatively Measure Hydroxyl Groups in Biomass As Their Original Structures

Frontiers in Energy Research, 2018
In this study, the dissolution of biomass components—cellulose, hemicellulose, and lignin, and two whole biomasses—switchgrass and poplar in a pyridine based ionic liquid at a low temperature—50°C has been examined, which will provide an opportunity to ...

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

Environmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Rheological and Textural Properties of Clean‐Label 3D‐Printed Traditional Thai Dessert

Food Bioengineering, EarlyView.
ABSTRACT This study aimed to develop a clean‐label 3D‐printable food ink using a formulation based on Khanom Piak Poon, a traditional Thai dessert, enriched with carrot powder (CP) for enhanced nutritional value. Unlike conventional food printing inks that contain additive hydrocolloids, this ink relies on the natural reactions between starch, sugar ...

Healthy Snacks Elaborated With Decoction Residues of Hibiscus sabdariffa L: Physical and Sensory Characteristics

Food Chemistry International, EarlyView.
Healthy snacks formulated with food by‐products are gaining interest within the food industry. Decoction residues of Hibiscus sabdariffa (roselle) retain thermostable polyphenols. Extruded snacks enriched with roselle showed a reduction in the expansion index as the roselle concentration increased.
