In this paper, the advanced preparation methods of nanocellulose are reviewed and their advantages and disadvantages are compared, especially the application of using a eutectic solvent to prepare nanocellulose instead of strong acid and strong base solvent is listed. In this paper, the wide application of nanocellulose in medicine, sewage treatment, electrochemistry, gas absorption and other fields is summarized, such as dr Read More

Background: Propane dehydrogenation (PDH) is the most potential propylene production technology, which can make up the large gap in downstream products of propylene. The catalyst supports lay the foundation for the catalytic activity and stability of the prepared catalysts in PDH reactions. Therefore, we focus on the discussion of single oxides, composite oxides, zeolites, and carbon materials as supports to demo Read More

Background: The development of cost-effective and high-activity hydrogen evolution reaction (HER) electrocatalysts is limiting the implementation of hydrogen production from electrochemical and photoelectrochemical water splitting, which is seen as a potential technology for clean energy production and long-term energy storage. Transition metal oxide catalysts, a large class of functional materials with variable elemental Read More

Background: Skin diseases represent a major health concern worldwide and negatively impact patients’ quality of life. Despite the availability of various efficacious drugs, their therapeutic outcome is often limited due to shortcomings related to the formidable skin barrier and unfavorable physicochemical properties of drugs. Flexible nano-vesicles have shown tremendous potential to overcome these hurdles and improve t Read More

Biodegradable nanogels in the biomedical field are emerging vehicles comprising dispersions of hydrogel nanoparticles having 3D crosslinked polymeric networks. Nanogels show distinguished characteristics including their homogeneity, adjustable size, low toxicity, stability in serum, stimuli-responsiveness (pH, temperature, enzymes, light, etc.), and relatively good drug encapsulation capability. Due to these character Read More

Ultraviolet (UV) radiation serves as a principal carter to dermatoheliosis, also professed as extrinsic aging or photoaging that encompasses premature skin vicissitudes secondary to damage instigated by chronic sun exposure. The present literature study embarks on the fundamental understanding of molecular/pathophysiological mechanisms and signals transduction pathways convoluted in the process of photoaging. Read More

Background: Yellow curcumin, the “Indian Gold” has been known since ancient times to modulate the activities of a wide variety of targets. The voluminous literature and several patents are proof of the therapeutic value of curcumin. Tetrahydrocurcumin (THC), however, has remained an unexplored molecule, although its cosmeceutical properties have been documented. Their compromised bioavailability, poor aqueous s Read More

Fabricating materials with nacre-like structure have received considerable attention as it shows an excellent combination of mechanical strength and toughness. A considerable number of researchers have reported the preparation method of bionic structure, such as layer-by-layer assembly, vacuum filtration, coextrusion assembly, electrophoresis deposition, water-evaporation-induced assembly, 3D printing, and freeze castin Read More

Recently, renewable and non-conventional energy production methods have been getting widespread attention. Fast research progress in establishing green energy indicates the relevance of carbon-free power production. Chemical energy stored in hydrogen molecules is considered green energy to substitute conventional energy sources. It is possible to produce hydrogen without carbon emission by water electrolysi Read More

Background: Non-invasive microwave hyperthermia approaches suffer from several limitations, such as maximum energy localization in the target tissue, reduced unwanted hotspots, less penetration time at specific penetration depth, and maximum directivity of applicators. For conformal body structures, curved patch applicators avoid mismatch losses and provide circular polarization to achieve maximum power deposition at t Read More

Introduction: The current research aims to formulate a controlled release formulation of Actarit utilizing cyclodextrin based nanosponges as a nanocarriers. β-Cyclodextrin built nanosponges were prepared by condensation reaction using diphenyl carbonate as crosslinking agent. Methods: A 3-level, 3-factor Box-Behnken design was used to optimize the reaction conditions. The particle size, zeta potential and solubilization ef Read More

Background: We reported for the first time the preparation of carbon nanodots/ cajuput oil (C-dots/CJO) composites for potential antibacterial applications. Methods: The C-dots were synthesized from CJO distillation wastes via the low carbonization method. Then, the C-dots were mixed with CJO to obtain C-dots/CJO composites. The characteristics of the C-dots were determined using UV-Vis, PL, TRPL, FTIR, and HRTEM, w Read More
