Abstract Upgrading of abundant cellulosic biomass to isosorbide can reduce the dependence on limited fossil resources and provide a sustainable way to produce isosorbide, utilized for polymers, medicine and health care product synthesis. This review comprehensively examines the key steps and catalytic systems involved in the conversion of cellulose to isosorbide. Initially, the reaction pathway from cellulose to isosorbide is elucidated, emphasizing three critical steps: cellulose hydrolysis, glucose hydrogenation, and the two-step dehydration of sorbitol to produce isosorbide. Additionally, the activation energy and acidic sites during cellulose hydrolysis, the impact of metal particle size and catalyst More > Graphic Abstract

Abstract Piezoelectric materials convert mechanical energy into electrical energy, acting as renewable energy sources. As smart materials, they respond to environmental changes by altering their properties. When pressure is applied, their structure separates positive and negative charge centers, producing opposite charges on crystal surfaces. This generates an electric field and a measurable potential. Wood, a natural material, also exhibits piezoelectric behavior. The piezoelectric effect of wood was first discovered by Russian scientists in 1940–1950. Then, in 1955, Fukada analyzed both the direct and inverse piezoelectric effect of wood and scientifically proved that this natural material has… More > Graphic Abstract

Abstract Natural nanofibers, e.g., cellulose nanofiber (CNF) of plant, collagen fibril in human body and fibroin fiber in spider silk, show interesting and distinctive atomistic mechanisms in deformation under mechanical loading as well as exhibition of extraordinary strength. These fibers are comprising more larger bulk and wire materials by constructing structural hierarchy. However, the initiation of unique behavior of these materials largely originates from atomic-scale and chemical energetics in loading. Besides, the experimental approach is often difficult and is too limited to reveal the basic mechanism. Therefore, it is crucial to clarify atomic behavior of these… More >

Abstract As oil is now an important resource for the survival and development of mankind, the consumption of oil continues to increase each year, and there have been a number of major oil spills in history, such as the oil spill from the Deepwater Horizon drilling rig. Therefore, oil spills during storage and transportation have become an issue of serious concern. Current methods such as incineration and chemical methods cause secondary environmental pollution and fail to enable resource recovery. The adsorption method by porous materials has attracted worldwide attention due to its simplicity, portability, and efficiency.… More > Graphic Abstract

Abstract Commercial lithium-ion batteries (LIBs) use polyolefins as separators. This has led to increased research on separators composed of renewable materials such as cellulose and its derivatives. In this study, the ionic conductivity of cellulose acetate (CA) polymer electrolyte membranes was enhanced via plasticization with citric acid and succinonitrile. The primary objective of this study was to evaluate the effectiveness of these plasticizers in improving cellulose-based separator membranes in LIBs. CA membranes were fabricated using solution casting technique and then plasticized with various concentrations of plasticizers. The structural, thermal, and electrochemical properties of the resulting membranes… More > Graphic Abstract

Abstract Traditional materials are emerging increasingly severe problems such as environmental pollution, non-renewability, and resource waste. As the most abundant natural biomass in nature, nanocellulose materials are expected to become a new generation of green, biodegradable, high-performance structural materials and contribute to sustainable development. Starting from the intrinsic relationship between hydrogen bonding network and microstructure deformation in nanocellulose, we performs the bottom-up multiscale mechanics methods, combing theoretical modeling, experimental characterization and material preparation, to reveal the physical mechanism and key characteristic parameters of the microstructure-regulated mechanical behaviors of nanocellulose materials, further establishing the cross-scale relationship between… More >

Abstract Kink defects are prevalent in nanocellulose. The existence of diverse kink patterns lacking molecular-scale resolution has caused uncertainty regarding the mechanisms governing the formation of different kinks in nanocellulose, including both reversible and irreversible kinks. The constraints resulting from these limitations often lead to significant confusion in exploring the structure-property relationships of nanocellulose. By integrating AFM experiments with molecular dynamics simulations, we examined the microstructure-dependent kink deformations in nanocellulose (Iβ phase) and the resultant local microstructural damages. In atomic force microscopy images, bent nanofibrils typically display minor curvatures, whereas kinked nanofibrils exhibit pronounced sharp bends,… More >

Abstract This research aimed to investigate the effect of pulping conditions and refining intensities of wheat straw to be recommended for fluff pulp production. For this purpose, mono ethanol amine (MEA) was selected as a de-lignification agent at three levels of 50:50, 25:75, and 15:85 (MEA/water, W/V %), and soda-AQ 14 W/V % was used as a reference pulping. To investigate the optimal refining intensity, the obtained pulp was passed through a single disk laboratory refiner from 0 to 6 times and in two different consistencies (1.5 and 2.5 W/V %). Total yield, kappa number, ash… More > Graphic Abstract
