Characterisation of Long-term Changes in Photolysis Rate in Beijing based on Observation and Simulation

open access: yesGaoyuan qixiang
To investigate the evolutionary patterns of atmospheric photochemical parameters and the influence mechanisms of aerosols in Beijing, this study analyzed the spatiotemporal characteristics of nitrogen dioxide photolysis rate J(NO2) and explored the ...

Airborne lidar stratospheric ozone and aerosol investigations [PDF]

open access: yes
The objectives are to study the distribution of ozone (O3) and aerosols across the polar regions during the winter and spring periods and to relate these observations to chemical and dynamical processes that can contribute to the chemical perturbation of

i‐Tac: Inverse Design of 3D‐Printed Tactile Elastomers with Tuneable Optical and Mechanical Properties

open access: yesAdvanced Intelligent Systems, EarlyView.
Inspired by the multi‐tissue architecture of the human fingertip dermis (A), this work introduces a mixture design using three PolyJet materials (AC/TM/GM) to expand the achievable elastomer property space (B). An inverse design pipeline (i‐Tac) is developed to map target optical/mechanical requirements to optimal material compositions (C), enabling ...

Robotic Arm‐Assisted Conformal 3D Printing of Displays for Structural Electronics

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a robotics‐enabled platform combining 3D scanning and a 6‐DOF robotic arm for conformal printing on complex non‐planar structures. By maintaining nozzle perpendicularity, the system enables high‐fidelity direct ink writing on steep sidewalls, spherical surfaces, successfully demonstrating a fully printed 7‐segment dynamic display ...

Retrieval of Volcanic and Man-Made Stratospheric Aerosols from Orbital Polarimetric Measurements [PDF]

open access: yes
Stratospheric aerosols that are caused by a major volcanic eruption can serve as a valuable test of global climate models, as well as severely complicate tropospheric-aerosol monitoring from space.

Effect of Budesonide Nasal Irrigation in Patients With Chronic Rhinosinusitis With Nasal Polyps Without Prior Sinus Surgery: A Randomized, Double‐Blind, Placebo‐Controlled Study

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The indication for nasal irrigation with corticosteroids after sinus surgery in patients with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is well established, as surgery facilitates distribution throughout the sinonasal cavity.

Humid Summers Promote Urban Aqueous‐Phase Production of Oxygenated Organic Aerosol in the Northeastern United States

open access: yesGeophysical Research Letters
Aqueous‐phase uptake and processing of water‐soluble organic compounds can promote secondary organic aerosol (SOA) production. We evaluated the contributions of aqueous‐phase chemistry to summertime urban SOA at two sites in New York City.
