CRISPR/Cas9‐Assisted Microrobots for Fast and Ultrasensitive “On‐The‐Fly” Next‐Generation DNA Detection

open access: yesAdvanced Functional Materials, EarlyView.
This work presents self‐propelled CRISPR/Cas9‐functionalized Au–MRs for rapid, amplification‐free, “on‐the‐fly” DNA detection. By harnessing motion‐assisted signal recovery, the platform achieved the limit of detection in low fM DNA concentrations, enabling detection across a wide dynamic range within only 5 min, which is significantly faster than any ...

Photothermal effects in ultra-precisely stabilized tunable microcavities

open access: yes, 2016
We study the mechanical stability of a tunable high-finesse microcavity under ambient conditions and investigate light-induced effects that can both suppress and excite mechanical fluctuations.

Defect‐Mediated Scintillation in Fully Inorganic Perovskites via Water‐Induced 0D/3D Phase Modulation

open access: yesAdvanced Functional Materials, EarlyView.
A reproducible synthesis to control 3D/0D phase ratios via water‐tuned solvent–antisolvent methods is presented. Enhanced scintillation yield and ultrafast decay are achieved. Defect‐driven emission mechanisms are revealed through cathodoluminescence and radioluminescence, shedding light on the underexplored role of the 0D Cs4PbBr6 and mixed 0D/3D ...

Influence of Ambient Noise Source Distributions on Cross-correlation Derived Seismic Waveforms and Dispersion Curve Retrieval

open access: yesCT Lilun yu yingyong yanjiu
Dense-array observation has become a key method for obtaining high-resolution subsurface structures. However, the spatiotemporal heterogeneity of the noise source distribution significantly reduces the signal-to-noise ratio (SNR) of noise correlation ...

The Benefits of Sleep During Hospitalization: A Survey to Determine the Utility of Quiet Hours on a Med-Surg Floor [PDF]

open access: yes, 2017
Florence Nightingale said, “Unnecessary noise is the cruelest absence of care.” During inpatient hospitalizations, frequent awakenings and a high level of ambient noise prevent restful sleep in many patients.

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

High source levels and small active space of high-pitched song in bowhead whales (Balaena mysticetus). [PDF]

open access: yesPLoS ONE, 2012
The low-frequency, powerful vocalizations of blue and fin whales may potentially be detected by conspecifics across entire ocean basins. In contrast, humpback and bowhead whales produce equally powerful, but more complex broadband vocalizations composed ...
