Advances in the enhancement of mechanical and hydrophobic properties of nanocellulose-based packaging materials: A review.

As environmental issues are hotly debated worldwide, finding suitable materials to replace petroleum-based materials as the next-generation packaging materials has become a research hotspot. Nanocellulose, as a biomass material widely available in nature, is favored for application in green packaging materials due to its environmentally friendly and bio-friendly characteristics. However, the unstable mechanical properties and strong hydrophilicity of nanocellulose limit its practical application in packaging materials.

An electrostatically spun cellulose-based self-powered mask with high efficiency air filtration and ammonia sensing.

On construction sites impacted by particulate matter and hazardous gases, portable integrated air filtration equipment with high efficiency, minimal pressure drops and ammonia (NH) alarms is critical. Triboelectric nanogenerators (TENG) present a sustainable solution by generating self-powered electricity to fulfill these requirements. In this study, we synthesized zeolitic imidazolate framework-8 (ZIF-8) in situ on the surface of titanium carbide (TiCT) to create TiCT/ZIF-8, grafted it onto cellulose diacetate via tetraethyl orthosilicate, and ultimately developed a cellulose-based nanofibrous membrane through electrospinning, combining it with a negative triboelectric material to construct a self-powered TENG-based mask.

Current status of research on polysaccharide-based functional gradient gel materials: A review.

Functional gradient materials with material property anisotropy are one of the hotspots of current new material research. The gradient change of material properties comes from the change of the content of one or more components in the material, which is closely related to the preparation process of the material. Meanwhile, polysaccharide materials, as an environmentally friendly and green material, have attracted extensive attention from researchers.

A comprehensive review on preparation and functional application of the wood aerogel with natural cellulose framework.

As the traditional aerogel has defects such as poor mechanical properties, complicated preparation process, high energy consumption and non-renewable, wood aerogel as a new generation of aerogel shows unique advantages. With a natural cellulose framework, wood aerogel is a novel nano-porous material exhibiting exceptional properties such as light weight, high porosity, large specific surface area, and low thermal conductivity. Furthermore, its adaptability to further functionalization enables versatile applications across diverse fields.

High expression of NXPH4 correlates with poor prognosis, metabolic reprogramming, and immune infiltration in colon adenocarcinoma.

Background: Colon adenocarcinoma (COAD) is a prevalent gastrointestinal malignant disease with high mortality rate, and identification of novel prognostic biomarkers and therapeutic targets is urgently needed. Although neurexophilin 4 (NXPH4) has been investigated in several tumors, its role in COAD remains unclear. The aim of this study was to explore the prognostic value and potential functions of NXPH4 in COAD.

Application progress of nanocellulose in food packaging: A review.

With the increasing environmental and ecological problems caused by petroleum-based packaging materials, the focus has gradually shifted to natural resources for the preparation of functional food packaging materials. In addition to biodegradable properties, nanocellulose (NC) mechanical properties, and rich surface chemistry are also fascinating and desired to be one of the most probable green packaging materials. In this review, we firstly introduce the recent progress of novel applications of NC in food packaging, including intelligent packaging, nano(bio)sensors, and nano-paper; secondly, we focus on the modification techniques of NC to summarize the properties (antimicrobial, mechanical, hydrophobic, antioxidant, and so on) that are required for food packaging, to expand the new synthetic methods and application areas.

Cellulose Nanofiber-Based Triboelectric Nanogenerators for Efficient Air Filtration in Harsh Environments.

Advanced portable healthcare devices with high efficiencies, small pressure drops, and high-temperature resistance are urgently desired in harsh environments with high temperatures, high humidities, and high levels of atmospheric pollution. Triboelectric nanogenerators (TENGs), which serve as energy converters in a revolutionary self-powered sensor device, present a sustainable solution for meeting these requirements. In this work, we developed a porous negative triboelectric material by synthesizing ZIF-8 on the surface of a cellulose/graphene oxide aerogel, grafting it with trimethoxy(1,1,2,2-heptadecafluorodecyl)silane, and adding a negative corona treatment, and it was combined with a positive triboelectric material to create a cellulose nanofiber-based TENG self-powered filter.

Cyanobacterial VOCs β-ionone and β-cyclocitral poisoning Lemna turionifera by triggering programmed cell death.

β-Ionone and β-cyclocitral are two typical components in cyanobacterial volatiles, which can poison aquatic plants and even cause death. To reveal the toxic mechanisms of the two compounds on aquatic plants through programmed cell death (PCD), the photosynthetic capacities, caspase-3-like activity, DNA fragmentation and ladders, as well as expression of the genes associated with PCD in Lemna turionifera were investigated in exposure to β-ionone (0.2 mM) and β-cyclocitral (0.

Characterization and Efficacy of a Nanomedical Radiopharmaceutical for Cancer Treatment.

Although much progress has been made over the last decades, there is still a significant clinical need for novel therapies to manage cancer. Typical problems are that solid tumors are frequently inaccessible, aggressive, and metastatic. To contribute to solving some of these issues, we have developed a novel radioisotope-labeled 27 nm nanoparticle, Lu-SN201, to selectively target solid tumors via the enhanced permeability and retention effect, allowing irradiation intratumorally.

Dosimetric Comparison of Intensity-Modulated Radiotherapy, Volumetric Modulated Arc Therapy and Hybrid Three-Dimensional Conformal Radiotherapy/Intensity-Modulated Radiotherapy Techniques for Right Breast Cancer.

This study aimed to compare different types of right breast cancer radiotherapy planning techniques and to estimate the whole-body effective doses and the critical organ absorbed doses. The three planning techniques are intensity-modulated radiotherapy (IMRT), volumetric modulated arc therapy (VMAT; two methods) and hybrid 3D-CRT/IMRT (three-dimensional conformal radiotherapy/intensity-modulated radiotherapy). The VMAT technique includes two methods to deliver a dose: non-continuous partial arc and continuous partial arc.

Vertical nanowire arrays as a versatile platform for protein detection and analysis.

Protein microarrays are valuable tools for protein assays. Reducing spot sizes from micro- to nano-scale facilitates miniaturization of platforms and consequently decreased material consumption, but faces inherent challenges in the reduction of fluorescent signals and compatibility with complex solutions.

Specific and reversible immobilization of histidine-tagged proteins on functionalized silicon nanowires.

Silicon nanowire (Si NW)-based field effect transistors (FETs) have shown great potential as biosensors (bioFETs) for ultra-sensitive and label-free detection of biomolecular interactions. Their sensitivity depends not only on the device properties, but also on the function of the biological recognition motif attached to the Si NWs. In this study, we show that SiNWs can be chemically functionalized with Ni:NTA motifs, suitable for the specific immobilization of proteins via a short polyhistidine tag (His-tag) at close proximity to the SiNW surface.
