Abstract Highly permeable particulate matter (PM) can carry various bacteria, viruses and toxics pose a serious threat to public health. Nevertheless, current respirators typically sacrifice their thickness base weight for high-performance filtration, which inevitably causes wearing discomfort significant consumption of raw materials. Here, we show facile yet massive splitting eletrospinning strategy prepare an ultrathin, ultralight radiative cooling dual-scale fiber membrane with about 80% infrared transmittance high-protective, comfortable sustainable air filter. By tailoring antibacterial surfactant-triggered charged jets, the fibrous filter consisting continuous nanofibers (44 ± 12 nm) submicron-fibers (159 32 is formed. It presents ultralow (1.49 μm) (0.57 g m −2 ) but superior protective performances (about 99.95% PM 0.3 removal, durable ability) comfort low resistance, high heat dissipation moisture permeability. Moreover, save over 97% polymers than commercial N95 respirator, enabling itself be economical. This work paves way designing advanced

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

Nano Letters, Год журнала: 2024, Номер 24(9), С. 2861 - 2869

Опубликована: Фев. 26, 2024

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

Hybrid Cellulose‐Based Systems for Triboelectrification in Aerosol Filtration, Ammonia Abatement and Respiration Monitoring

Advanced Functional Materials, Год журнала: 2024, Номер 34(19)

Опубликована: Янв. 10, 2024

Abstract The dissipation of charges by aging or under the effect humid conditions considerably impedes a broader utilization electrostatic fields in aerosol filtration. This study introduces respiration‐driven air filter (RAF) that continuously generates triboelectric within pair tribolayers, which facilitates sustained filtration performance. Such system is integrated multilayer unit inserted personal protective equipment (RAFM) to efficiently capture, sense, and degrade airborne pollutants with no need for external power sources. nanogenerator‐based RAF replenishes static maintains an field through breathing contact‐electrification between two cellulose‐based tribolayers: cellulose/metal organic framework cryogel (electron donor) cellulose–based electrospun membrane acceptor). Notably, RAF's tribolayer substantially enhances both efficiency (up 93.8% 0.3 µm particulate matter) sensing/catalytic degradation (ammonia; >20%). When circuit module, RAFM effectively monitors respiration dynamics, acting as indicator/regulator. Overall, this adds promise tribogeneration materials its application exposure‐risk operations.

Optical sorting: past, present and future

Light Science & Applications, Год журнала: 2025, Номер 14(1)

Опубликована: Фев. 27, 2025

Optical sorting combines optical tweezers with diverse techniques, including spectrum, artificial intelligence (AI) and immunoassay, to endow unprecedented capabilities in particle sorting. In comparison other methods such as microfluidics, acoustics electrophoresis, offers appreciable advantages nanoscale precision, high resolution, non-invasiveness, is becoming increasingly indispensable fields of biophysics, chemistry, materials science. This review aims offer a comprehensive overview the history, development, perspectives various categorised passive active methods. To begin, we elucidate fundamental physics attributes both conventional exotic forces. We then explore sorting, which fuses diversity Raman spectroscopy machine learning. Afterwards, reveal essential roles played by deterministic light fields, configured lens systems or metasurfaces, particles based on their varying sizes shapes, resolutions speeds. conclude our vision most promising futuristic directions, AI-facilitated ultrafast bio-morphology-selective It can be envisioned that will inevitably become revolutionary tool scientific research practical biomedical applications.
