Hierarchical Flexible Ceramic Nanofiber Membrane for Simultaneous Membrane Distillation and Photocatalytic Hydrogen Evolution

Advanced Materials, EarlyView.
A hierarchical flexible ceramic nanofiber membrane integrates a La‐stabilized ZrO2 scaffold with superhydrophobic UiO‐66‐NH2/CdS heterojunctions. The gas–liquid–solid interfacial architecture sustains vapor‐selective desalination, visible‐light charge separation, and rapid H2 extraction, enabling simultaneous freshwater production and photocatalytic ...

A joint denoising method of pulse signal based on improved wavelet-VMD

Dianzi Jishu Yingyong
To address the problem of substantial noise introduced during the actual measurement of pulse signals due to environmental changes, subject motion, electromagnetic interference, and other factors, this paper proposes a denoising algorithm based on ...

Structural and Dynamic Properties of Lipid‐Coated Gold Nanoparticles

Advanced Materials Interfaces, EarlyView.
Atomistic molecular dynamics simulations reveal how lipid chemistry governs the behavior of coatings on the surface of a gold nanoparticle. Variations in headgroup charge and acyl‐chain saturation produce distinct monolayer‐like lipid organization, ranging from compact, ordered coatings to extended, dynamic shells. These findings establish a foundation

Backbone Steric Constraints Underlie High Passive Membrane Permeability of N‐Alkyl Peptides

Angewandte Chemie, EarlyView.
Beyond amide hydrogen removal, steric constraints encoded in N/Cα‐dually substituted backbones are uncovered as a key determinant of passive membrane permeability in N‐alkyl peptides. These constraints restrict conformational freedom and sterically limit backbone hydration during membrane permeation.

To VMD, or not to VMD, in the quark-gluon plasma

, 1995
I review results on the shift of the $ρ$ meson mass at nonzero temperature in a gauged linear sigma model, under the assumption of strict vector meson dominance. (Based upon a talk presented at the International Workshop on "Chiral Dynamics in Hadrons and Nuclei", Seoul, Korea, Feb., 1995).

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

VMD–WT-Based Method for Extracting On-the-Fly GNSS Tide Level and Its Realization

, 2022
In this paper, a method for extracting the on-the-fly (OTF) GNSS tide level was designed by combining variational modal decomposition (VMD) and a wavelet thresholding (WT) method to improve the extraction accuracy of the OTF GNSS tide level.
