Abstract Load frequency control (LFC) is a critical function to balance the power consumption and generation. The grid frequency is a crucial indicator for maintaining balance. However, the widely used information and communication infrastructure for LFC increases the risk of being attacked by malicious actors. The dynamic load altering attack (DLAA) is a typical attack that can destabilize the power system, causing the grid frequency to deviate from its nominal value. Therefore, in this paper, we mathematically analyze the impact of DLAA on the stability of the grid frequency and propose the network parameter regulation (NPR)… More >

Abstract Nitrogen-doped activated carbon (N-AC) was successfully prepared by KOH-activation and nitrogen doping using ammonia (NH₃) heat treatment. Coconut shell-derived activated carbon (AC) was heat-treated under NH₃ gas in the temperature range of 700°C–900°C. Likewise, the mixture of potassium hydroxide (KOH) and AC was heated at 800°C, followed by heat treatment under NH₃ gas at 800°C (hereafter referred to as KOH-N-AC800). Scanning electron microscopy (SEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and Brunauer-Emmett-Teller (BET) method were utilized to analyze morphology, crystallinity, chemical bonding, chemical composition and surface area. The surface area and porosity of N-AC increased with increasing… More >

Abstract Silicon nitride (Si₃N₄) ceramics with outstanding comprehensive properties, have become important candidate materials for components like radomes and antenna windows. In this study, the vat photopolymerization (VPP) technique was used to fabricate Si₃N₄ ceramic radomes. Our research centered on optimizing the curing properties of ceramic slurries and precisely regulating the comprehensive properties of the ceramics. Several methods were proposed to modify the curing depth of Si₃N₄ ceramic slurry, including thermosetting resin coating, sintering aid coating, oxidation coating, double coating, etc. Moreover, a pore-forming agent modification method was also proposed, which enabled the VPP printing of Si₃N₄ ceramic More >

Abstract Gastric Cancer (GC) is a highly prevalent and poorly prognostic gastrointestinal malignancy with low overall treatment efficacy worldwide. Early diagnostic markers and potential therapeutic targets for GC treatment are urgently needed. UFMylation, a novel ubiquitin-like modification is indispensable for numerous fundamental cellular processes. Deficiency in this modification is reported to be associated with several human diseases including cancer. Accumulating evidence suggests that the expression of the key UFMylation components is closely associated with GC cell proliferation, invasion, metastasis, and chemotherapy resistance. Recent clinical studies have further highlighted the prognostic value and therapeutic potential of UFMylation More >

Abstract The prolonged health monitoring using wearable technology faces challenges stemming from perspiration, including bacterial proliferation, compromised adhesion, signal quality deterioration, and user discomfort. Notably, excessive sweat fosters bacterial colonization, escalating infection risks, and compromising biomarker analysis. Existing antibacterial approaches, unfortunately, risk disrupting the delicate balance of skin microbiota. To address this, we’ve developed a Janus patch featuring Zn-Al layered double hydroxide (LDH) modification, which boasts sustained antibacterial properties while preserving the epidermal microecology. It integrates a hydrophobic LDH fabric that mechanically eradicate bacteria via a nanoknife effect, and a laser-engraved medical adhesive with microholes for More >

Abstract Podophyllotoxin is a well-studied natural product. Because of its unique structure and ability to inhibit cancer cells, it has been changed in different ways to find out its pharmacological properties. This paper discusses the common chemical modifications of podophyllotoxin molecules, including the C-4 and E-4 site replacements. Furthermore, its common inhibitory effects on cancer cells and antiparasitic activities, among others, are outlined by the connection between conformational changes and pharmacological activities. Importantly, Podophyllotoxin can effectively overcome the phenomenon of multidrug resistance through a dual-targeting mechanism, including inhibition of microtubule protein synthesis and topoisomerase II activity, More > Graphic Abstract

Abstract In this paper, the stability of the results of ultrasonic wood surface modification after long-term storage, including macroscopic properties and microstructure of specimens, was investigated. Specimens of aspen wood (Populus tremula) were processed by the developed ultrasonic method of wood surface modification in three different treatment modes and the surface hardness of the specimens was evaluated after processing and after storing the specimens for more than 5 years since long-term stability is an important factor for the use of ultrasonically modified sawn timber as construction and finishing materials. The obtained results of surface hardness measurements by… More > Graphic Abstract

Abstract Under the background of the current energy crisis and environmental pollution, the development of green and sustainable materials has become particularly urgent. As one of the most abundant natural polymers on earth, cellulose has attracted wide attention due to its green recycling, sustainable development, degradability, and low cost. Therefore, cellulose and its derivatives were used as the starting point for comprehensive analysis. First, the basic structural properties of cellulose were discussed, and then the extraction and utilization methods of cellulose were reviewed, including Sodium Hydroxide based solvent system, N, N-Dimethylacetamide/Lithium Chloride System, N-Methylmorpholine-N-Oxide (NMMO) system, More > Graphic Abstract

Abstract Polylactic acid (PLA), a biodegradable polymer, exhibits superior mechanical strength and processability. However, its broader adoption is hindered by inherent brittleness, low hydrophilicity, and sluggish crystallization kinetics. Chitosan (CS), a natural polysaccharide renowned for its biocompatibility and biodegradability, offers potential to address these limitations. While both materials have garnered significant attention in materials science, research on their integration via melt blending and the resulting performance enhancements for food-contact plastics remains understudied. This research comprehensively explores how different levels of CS content, from 0% to 10%, impact the characteristics of chitosan/polylactic acid (CS/PLA) composites. It specifically… More >

Abstract Food packaging is becoming popular as the consumption of ready-to-eat food products rises. Easy-to-use, non-biodegradable plastic packaging is commonly used in food packaging, contributing to the deteriorating environmental situation. This issue increases the concern for the environment and encourages the usage of alternative materials. Cellulose nanofibrils (CNF) are abundant and biodegradable, which makes them ideal candidates to replace plastic coatings. The ability to form H-bonds between the hydroxyl groups makes coated paper with CNF have good strength, but poor barrier properties. The barrier properties can be improved by grafting DMAEMA or HEMA onto CNF (CNF-g-PDMAEMA… More > Graphic Abstract
