Air pollution threats to human health have increased awareness of the role filter units in air cleaning applications. As an ideal energy-saving strategy for filters, slip effect on nanofiber surfaces can potentially overcome trade-off between filtration efficiency and pressure drop. However, potential nanofibrous structures is significantly limited by tight stacks. In this study, trichome-like biomimetic (TLB) filters with 3D-templated silicone nanofilaments (average diameter: ≈74 nm) are...
Extrusion-based 3D printing holds great potential for manufacturing solid propellants. Among the various methods, screw- and plunger-based extrusion are most frequently reported techniques propellant printing, each employing different mechanisms. This paper compares flow characteristics of these two methods through a combination simulations experiments. Simulation results reveal that slurry in plunger device exhibits relatively stable characteristics, especially near nozzle outlet, with high...
Abstract Air filtration is vital for passive pollution control toward advanced manufacturing industries and human health protection. However, large‐scale air‐filter utilization limited by high energy costs. Therefore, it crucial to develop filter media that exhibit a removal efficiency, low pressure drop, stable biocidal effects. This study reports an efficient scalable bottom‐up approach fabricating shellac‐based glass fiber matrices with bioprotective traps (GFMs‐traps) tunable conformal...
Abstract Exposure to bioaerosols can result in severe infection and even death, prompting the development of numerous air filters capture inactivate bioaerosols. Although wettability filter media determines its bioaerosol‐capture efficiency, dynamic collision behavior multiscale aqueous on most is poorly understood. A double‐gradient Janus paper (Janus paper) with a pore‐size gradient, asymmetric wettability, biocidal bioadhesion properties fabricated this study using an industrially...
Pleated filter media are widely used in particulate filtration, but the particle deposition and pressure drop during loading remain insufficiently explored. This study visualizes patterns pleated media, along with evolution of effective filtration area (EFA) using simulations. The results indicate that, as volume deposited particles increases, initially grows linearly, this rate increase accelerates continues. characteristics related to pleat ratio. A smaller ratio a initial EFA, leading...
The decontamination of chemical warfare agents (CWAs) from contaminated surfaces is critical importance due to the severe threats posed by CWAs human health and environment, particularly given persistent threat weapons since World War I. In this study, a novel UiO-66-NH2 crosslinked hyaluronic acid (HA) hydrogel was developed in presence polyvinyl alcohol under ambient conditions, leveraging dual functionality amino-substituted zirconium-based metal–organic framework (Zr-MOF) as both...
Ultra-high-efficiency filter media ensure high air cleanliness but need periodic replacement due to pressure drop increase. Adding a pre-filter can extend the filtration system’s service lifetime, yet and main-filter matching lacks systematic study. This research explored how different combinations affected two-stage ultra-high-efficiency performance. study focused on five grades (F7–F9, H10, H11) two types of media, fiberglass composite. It was found that F8 had best effect extending...
A novel, entirely bio-derived polylactide carbohydrate copolymer (RP1) is used as a compatibilizer, to produce bacterial cellulose (BC) poly(l-lactide) (PLLA) nanocomposites with improved mechanical properties. Contact angle measurements of RP1 droplets on single BC nanofibres proved that it has higher affinity towards than PLLA. comparable Young's modulus, but lower tensile strength, When was blended PLLA at concentration 5 wt%, the modulus and strength resulting polymer blend decreased...
Airborne dust can cause engine wear and contribute to gas emission. This study developed a novel submicro-fiber filter medium provide protection engines against dust.

Bacterial cellulose (BC) is often regarded as a prime candidate nano-reinforcement for the production of renewable nanocomposites. However, mechanical performance most BC nanocomposites inferior compared with commercially available polylactide (PLLA). Here, manufacturing concept paper-based laminates used, i.e., "PaPreg," to produce nanopaper reinforced PLLA, which has been called "nanoPaPreg" by authors. It demon-strated that high-performance nanoPaPreg (vf = 65 vol%) tensile modulus and...
