Direct deposition on pre-cooled grids: a new approach to sub-millisecond cryoEM grid preparation. [PDF]
We describe a new method to prepare grids for cryoEM on the sub‐millisecond timescale.There has been a rapid expansion in new approaches to sample preparation for single‐particle cryoEM. One drive has been around speeding up the process both for the application of time‐resolved studies and in outrunning some of the negative effects which may come from ...

Dust Pollution Mitigation by Solar Farm Deployment in Northern China
Abstract Dust storms pose a growing threat to air quality and public health across northern China. As part of the carbon‐neutrality and clean‐air strategy, China is rapidly expanding solar farms, particularly in desert regions, yet their potential to mitigate dust pollution and improve downwind air quality remains poorly understood. Here, we develop an

Concurrent Cloud and Drizzle Observations From Synergistic Ground‐Based Measurements
Abstract Drizzle, a common feature of marine boundary layer clouds formed through collision‐coalescence, plays a key role in cloud microphysics and evolution. However, simultaneously retrieving cloud and drizzle properties from remote‐sensing observations remains challenging because drizzle droplets often dominate radar signals, masking cloud ...

Quantifying Black Carbon Mixing State Heterogeneity Using a Machine Learning Model
Abstract The climate impact of black carbon (BC) is strongly sensitive to the mass ratio of non‐BC coatings to BC (RBC). However, current global climate models (GCMs) typically assume a uniform composition within individual BC‐containing particle populations, neglecting the significant particle‐to‐particle RBC heterogeneity. To address this, we train a

Cooking Impacts PM1 in Suburban New York, With Implications for Respiratory Deposition
Abstract Sub–micron particulate matter (PM1) in the New York (NY) metropolitan area impacts air quality and human health. We characterized refractory black carbon (BC) and non–refractory (NR) PM1 in Mineola, NY during winter 2024 and NR‐PM1 during summer 2023.

Morphology‐Driven Ternary Pattern Space Spans Shallow Marine Clouds
Abstract Marine shallow clouds exhibit a variety of patterns, which have been the subject of extensive research. In this study, we introduce a new approach for their continuous classification using Moderate Resolution Imaging Spectroradiometer (MODIS) true color imagery.

An on‐chip mid‐infrared dichroic filter is demonstrated using an asymmetric directional coupler theory comprising a longitudinally segmented subwavelength‐grating waveguide and a strip waveguide. Suppressed slot‐like scattering loss and precise dispersion engineering yield flat‐top responses over 3.3–3.7 μm, ∼0.9 dB insertion loss, ∼1 dB/nm roll‐off ...

Direct nanoimprinting transforms mesoporous titania films into visible‐wavelength metasurfaces through a streamlined deposition‐and‐imprint process requiring no conventional lithography or etching. The resulting structures support pitch‐tunable guided‐mode resonances, symmetry‐controlled quasibound states in the continuum, structural‐color image ...

SERS Facemask for Rapid and Portable Sensing Mycobacterium Tuberculosis Antigens for TB Screening
Our study introduced an Au─Ag embedded covalent organic framework (U@COF) ‐mediated facemask for sensing TB antigen ESAT‐6/CFP‐10 complex in clinical droplet samples toward TB screening. Practical analysis of clinical samples demonstrated the availability of our facemask, which is capable of identifying the TB subjects (N = 17) from healthy candidates (
