Joint inversion of magnetic and gravity data using group lasso regularization

Earth, Planets and Space
Magnetic and gravity inversion has long attracted attention and research. A recent topic in such inversion studies is the magnetic and gravity joint inversion with the constraint that the derived magnetization and density models are correlated.

Photo‐Gated Corona Microfluidics

Advanced Science, EarlyView.
Photo‐gated corona microfluidics decouples optical programming from electric‐field actuation to enable reconfigurable manipulation on open, electrode‐pattern‐free surfaces. Near‐infrared irradiation locally melts paraffin, creating a reversible charge‐relaxation pathway that reconstructs the electric field.

3D inversion of full gravity gradient tensor data in spherical coordinate system using local north-oriented frame

Earth, Planets and Space, 2018
In this paper, we propose an inverse method for full gravity gradient tensor data in the spherical coordinate system. As opposed to the traditional gravity inversion in the Cartesian coordinate system, our proposed method takes the curvature of the Earth,

Thermal Control of Concentric Topographies Patterned by Dynamic Electro‐Templated Generated Chiral Solitonic Structures

Advanced Science, EarlyView.
An electro‐templating strategy directs the relaxation of cholesteric finger loops into discrete concentric rings whose geometry is electrically programmed. The photopolymerized structures retain the topological defect pattern and, upon heating, show reversible, castle‐like surface modulation.

Tri‐WOB: A Bistability‐Driven Variable Stiffness Origami Structure for Soft Robotic Arms

Advanced Science, EarlyView.
Inherent bistability in Waterbomb origami enables the Tri‐WOB to switch between compliant and stiff states. By stacking multiple modules, the robotic arm maintains stiffness without continuous energy input while achieving large contraction, free morphing, and load‐bearing/transportation capability.

Nanoparticle‐Mediated Bubble Suppression During Droplet Solidification for Mechanical Reinforcement

Advanced Science, EarlyView.
Nanoparticles mediate droplet solidification by raising nucleation temperature, refining dendrites, and slowing freezing‐front advance, thereby suppressing trapped air bubbles in droplet‐based 3D printing. This strategy reduces bubble volume fraction by ∼35% and increases compressive strength by up to 39%, offering a low‐cost route to stronger printed ...

Synergistic p53 Pathway Activation Through Sono‐Gene Therapy Induced by Ultrasound‐Triggered Theranostic Mesoporous Nanoparticles

Advanced Science, EarlyView.
Schematic representation of ultrasound‐mediated ICG/siCD24@MSN‐LCD from nanostructure to synergistic sono‐gene therapy. This nanoplatform targets ASGPR via the LCD shell, which dissociates to release loaded ICG and siCD24. The core mechanism involves ultrasound‐guided sonodynamic therapy by ICG and CD24 knockdown by siCD24, both activating the p53 axis

Structural Control Over Bicontinuous Emulsions from Solvent‐Transfer Induced Phase Separation Through Nanoparticle Loading

Advanced Science, EarlyView.
The nanoparticle loading enables effective control over the liquid domain size in bicontinuous interfacially jammed emulsion gels (bijels) produced through solvent‐transfer induced phase separation (STrIPS). The relationship between the nanoparticle loading and domain size profiles in STrIPS bijels is resolved through confocal microscopy and explained ...

Protonation‐Gated Orthogonal Control of Highly Efficient Molecular Motors With Broad Visible‐Light Responsiveness

Angewandte Chemie, EarlyView.
Reversible protonation gates coumarin‐based overcrowded‐alkene molecular motors by dynamically reshaping their conjugation topology. This strategy enables efficient, near‐quantitative unidirectional photoisomerization from blue–green to red‐shifted visible light up to 600 nm, while preserving motor function and allowing orthogonal light, heat, and acid/
