A field-deployable lateral flow assay for rapid and sensitive detection of nanoplastics.

Plastic pollution has emerged as a global concern, with nanoplastics posing a distinct threat due to their small size, high mobility, and persistence. However, conventional nanoplastic detection techniques often rely on sophisticated instruments and extensive preprocessing, limiting their on-site applicability. This study aimed to develop a rapid and portable lateral flow assay (LFA) for on-site detection of nanoplastics smaller than 200 nm in environmental water samples.

Photocatalytic Activation of Dealuminated Zeolite through In Situ Formation of Defective Graphene.

Adsorbents such as zeolite are widely used for volatile organic compounds (VOCs) removal, but a practical challenge is the decrease in VOCs removal efficiency under humid environment by competitive adsorption between water vapor and VOCs, which requires frequent regeneration using external energy. A combination of zeolites with photocatalytic materials can address this issue by oxidizing adsorbed VOCs from the zeolite surface to CO gas under light irradiation. Herein, the in situ formation of photocatalytic active defect-rich graphene is presented on a commercial zeolite surface (ZSM-5) when properly dealuminated ZSM-5 is exposed to an acetaldehyde/humid air mixture under visible light.

Laser-Based Selective Removal of EMI Shielding Layers in System-in-Package (SiP) Modules.

With the increasing complexity and integration density of System-in-Package (SiP) technologies, the demand for selective electromagnetic interference (EMI) shielding is growing.

Starfish-inspired tube feet for temporary and switchable underwater adhesion and transportation.

Temporary and reversible underwater adhesion is important for a number of robotic applications, including picking up objects, facilitating locomotion in confined environments, and attaching to surfaces during periods of observation. Here, we present a starfish-inspired tube foot composed of a soft hydrogel mouth and a rigid stem, fabricated by integrating two serially bonded cylindrical components with distinct mechanical properties. Upon swelling, the initially straight hydrogel cylinder undergoes a selective shape transformation into a soft, cupped pad that deforms to stretch and spread upon contact, enabling effective adhesion to target surfaces.

Developing an air impingement dry cleaning device and investigating the factors affecting nonfat dry milk residue removal from stainless steel surfaces.

Dry cleaning has been identified as one method for controlling allergen cross-contact or pathogen cross-contamination in low-moisture food (LMF) environments without introducing moisture. Therefore, an air impingement cleaning device was custom-designed and explored as a dry cleaning method to remove nonfat dry milk (NFDM) residue on stainless steel (SS) surfaces. We investigated the effects of water activity (a) of NFDM, residue thickness (THK), nozzle diameter (ND), ratio of nozzle height (NH) from the SS surface to the ND (NH/ND), and air pressure (AP) on the NFDM residue removal.
