文摘Cu nanoparticles exhibit excellent properties as high-temperature-resistant,conductive,heat-dissipating,and connecting materials.However,their susceptibility to oxidation poses a major challenge to the production of high-quality sintered bodies in the air,severely limiting their widespread adoption in power electronics packaging.This study presents a novel approach to the synthesis of Cu nanoparticles capped with oleylamine ligands.By employing a simple solvent-cleaning process,effective control of the density of oleylamine ligands on particle surfaces was achieved,resulting in high-performance Cu nanoparticles with both oxidation resistance and air-sintering susceptibility.Moreover,through our research,the solvent-cleaning mechanism was clarified,a model for the oleylamine ligand decomposition was developed,the air-sintering behavior of Cu nanoparticles was analyzed,and the impacts of both the sintered bodies and interfaces on the sintering performance were explained.Additionally,Cu nanoparticles subjected to 5 cleaning rounds followed by sintering at 280℃and 5 MPa in air were confirmed to be able to produce the highest shear strength(49.2±3.51 MPa)and lowest resistivity(6.15±0.32μΩ·cm).Based on these results,flexible capacitive pressure sensors with Cu sintered electrodes were fabricated and demonstrated a stable pressure-capacitance response over the temperature range of 25-250℃.These findings underscore the impressive robustness and durability of sintered structures and the potential for high-temperature applications of oleylamine-capped Cu nanoparticles.Our study provides reliable application demonstrations for the low-cost manufacture of high-performance power electronics packaging structures that can operate in high-current-density,high-heat-flow-density,high-temperature,and high-stress environments.

文摘The food industry prioritizes food safety throughout the entire production process.This involves closely monitoring and evaluating all potential sources of biological or chemical contamination,starting from entering raw materials into the production chain and continuing to the final product.Biofilms on food surfaces or containers can harbor dangerous pathogens,such as Listeria monocytogenes.Therefore,it is essential to continuously manage microbial contamination on food contact surfaces to prevent foodborne infections.Recently,there has been increasing interest in using nanomaterials as surface coatings with antimicrobial properties in the food industry,especially since traditional disinfectants or antibiotics may contribute to developing resistance.However,the use of antibiofilm materials for long-term food storage remains underexplored,and there is a notable lack of focused reviews on nanomaterialbased antibiofilm coatings specifically for long-term food preservation.This review aims to consolidate recently reported nanoparticle-based antibiofilm food packaging materials.We discuss the effectiveness of various metal and metal oxide nanoparticles and biopolymer nanocomposites in combating biofilms.Additionally,we highlight the growing importance of biodegradable nanocomposite materials for antibiofilm food packaging.Furthermore,we explore the mechanisms of action,processing methods,and safety aspects of these nanomaterials being developed for food packaging applications.

文摘Growing environmental concerns and the need for sustainable alternatives to synthetic materials have led to increased interest in bio-based composites.This study investigates the development and characterization of sustainable egg packaging waste(EPW)biocomposites derived from recycled wood fibers and fungal mycelium filaments as a natural binder.Three formulations were prepared using EPW as the primary substrate,with and without the addition of hemp shives and sawdust as co-substrates.The composites were evaluated for granulometry,density,mechanical strength,hygroscopic behavior,thermal conductivity,and fire performance using cone calorimetry.Biocomposites,composed exclusively of egg packaging waste,exhibited favorable fire resistance,lower total heat release(THR)and total smoke release(TSR),extended time to ignition(TTI),reduced hygroscopicity,and higher flexural strength.Biocomposites,containing hemp shives,demonstrated improved compressive strength and thermal insulation but showed weaker fire resistance.Biocomposites,incorporating sawdust,showed intermediate properties with the longest flameout time(TTF)and highest heat release values.Overall,the results demonstrate that EPW-based biocomposites can be tailored through substrate composition to achieve desirable combinations of mechanical,thermal,and fire-retardant properties,highlighting their potential as sustainable alternatives to conventional syntheticmaterials in building and packaging applications.

文摘The continuous increase in petroleum-based plastic food packaging has led to numerous environmental concerns.One effort to reduce the use of plastic packaging in food is through preservation using biopolymer-based packaging.Among the many types of biopolymers,chitosan is widely used and researched due to its non-toxic,antimicrobial,and antifungal properties.Chitosan is widely available since it is a compound extracted from seafood waste,especially shrimps and crabs.The biodegradability and biocompatibility of chitosan also showed good potential for various applications.These characteristics and propertiesmake chitosan an attractive biopolymer to be implemented as food packaging in films and coatings.Chitosan has been tested in maintaining and increasing the shelf life of food,especially seafood such as fish and shrimp,and post-harvest products such as fruits and vegetables.In addition to its various advantages,the properties and characteristics of chitosan need to be improved to produce optimal preservation.The properties and characteristics of chitosan are improved by adding various types of additive materials such as biopolymers,plant extracts,essential oils,and metal nanoparticles.Research shows that material additives and nanotechnology can improve the quality of chitosan-based food packaging for various types of food by enhancing mechanical properties,thermal stability,antimicrobial activity,and antioxidant activity.This review provides a perspective on the recent development and properties enhancement of chitosan composite with additives and nanotechnology,as well as this material’s challenges and prospects as food packaging.

文摘Laser debonding technology has been widely used in advanced chip packaging,such as fan-out integration,2.5D/3D ICs,and MEMS devices.Typically,laser debonding of bonded pairs(R/R separation)is typically achieved by completely removing the material from the ablation region within the release material layer at high energy densities.However,this R/R separation method often results in a significant amount of release material and carbonized debris remaining on the surface of the device wafer,severely reducing product yields and cleaning efficiency for ultra-thin device wafers.Here,we proposed an interfacial separation strategy based on laser-induced hot stamping effect and thermoelastic stress wave,which enables stress-free separation of wafer bonding pairs at the interface of the release layer and the adhesive layer(R/A separation).By comprehensively analyzing the micro-morphology and material composition of the release material,we elucidated the laser debonding behavior of bonded pairs under different separation modes.Additionally,we calculated the ablation threshold of the release material in the case of wafer bonding and established the processing window for different separation methods.This work offers a fresh perspective on the development and application of laser debonding technology.The proposed R/A interface separation method is versatile,controllable,and highly reliable,and does not leave release materials and carbonized debris on device wafers,demonstrating strong industrial adaptability,which greatly facilitates the application and development of advanced packaging for ultra-thin chips.

文摘This study aims to the factors influencing consumer intention to purchase eco-friendly,small-packaged agricultural products using the Theory of Planned Behavior(TPB).With increasing demand for sustainable consumption,eco-friendly food packaging has become a critical focus within the circular economy.This study was conducted in Seoul,South Korea,a key marketplace for consumer trends,and surveyed 200 respondents to examine key TPB components—attitude,subjective norms,and perceived behavioral control—along with additional factors shaping sustainable purchasing behavior.The findings indicate that perceived behavioral control is the predictor of purchase intention(β=0.510,p<0.001),followed by attitude(β=0.236,p<0.05)and subjective norms(β=0.199,p<0.05).Moreover,the results suggest that while social influences play a role,individuals who perceive fewer barriers and have a stronger personal attitude toward sustainability are more likely to adopt eco-friendly purchasing behaviors.These results highlight the importance of consumer autonomy and confidence in making eco-friendly choices,suggesting that increasing accessibility and affordability of sustainable packaging can drive adoption.Despite social influences,urban consumers prioritize personal values and perceived control over purchasing behavior.The study might contribute to sustainability literature by offering insights into eco-conscious consumer behavior and implications for marketing strategies that promote sustainable agricultural products.Future research should explore cross-cultural comparisons and additional psychological determinants to enhance the understanding of sustainable consumption patterns.
