Tailoring Piezoelectric Nanogenerators and Microdevices for Cellular Excitation: Impact of Size and Morphology

open access: yesAdvanced Science, EarlyView.
Piezoelectric microdevices, composed of ZnO nanosheets acting as nanogenerators and grown on silicon microparticles, are designed and fabricated to deliver precise electrical cell stimulation. This study optimizes nanosheet growth and microparticle size to enhance electrical cell activation performance while minimizing cellular internalization.

Gentle Label‐Free Nonlinear Optical Imaging Relaxes Linear‐Absorption‐Mediated Triplet

open access: yesAdvanced Science, EarlyView.
The phototoxicity in nonlinear optical microscopy arises mainly from linear absorption of intrinsic biomolecules rather than nonlinear absorption. This mechanism is supported by a reproducible phototoxicity assay based on widely available chicken breast.

Single‐Pixel Infrared Miniaturized Spectrometer Enabled by Ultra‐Broadband Reconfigurable Photodetection

open access: yesAdvanced Science, EarlyView.
A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,

In Vivo Cytosolic Delivery of Biomolecules into Neurons for Super‐Resolution Imaging and Genome Modification

open access: yesAdvanced Science, EarlyView.
The N1 peptide specifically targets neurons, enabling cytosolic delivery of fluorescent dyes and proteins for super‐resolution imaging and functional genetic modification. Abstract Efficient delivery of biomolecules into neurons has significant impacts on therapeutic applications in the central nervous system (CNS) and fundamental neuroscience research.

Phase-resolved spectroscopy and photometry of the eclipsing polar EP Draconis (=H1907+690)

open access: yes, 1997
We present phase-resolved optical spectroscopy and CCD photometry of the faint eclipsing polar EP Dra (H1907+690). A revised ephemeris is derived which connects all 32000 binary cycles since its discovery by Remillard et al. (1991).

Unveiling Surface Species Formed on Ni‐Fe Spinel Oxides During the Oxygen Evolution Reaction at the Atomic Scale

open access: yesAdvanced Science, EarlyView.
≈1 nm thick amorphous layer with a higher oxygen concentration is formed on the surfaces of pristine P‐doped NiFe2O4 and activated NiFe2O4. Such surface layer is thought to significantly promote the charge transfer kinetics compared to the oxyhydroxide layer grown on Ni1.5Fe1.5O4 during the oxygen evolution reaction. Abstract Optimizing electrocatalyst
