From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Photo‐responsive carbon dots for pyroptosis‐mediated anti‐tumor application

Responsive Materials, EarlyView.
Photo‐responsive CDs generate ROS to induce tumor cell pyroptosis, thereby stimulating antitumor immunity. Abstract Pyroptosis refers to a kind of lytic programmed cell death, characterized by the release of pro‐inflammatory cytokines during the process. Owing to its immune response stimulation ability, pyroptosis has garnered considerable attention in

Ultrafast characterization of plasma critical surface evolution in inertial confinement fusion experiments with chirped laser pulses

High Power Laser Science and Engineering
Laser-driven inertial confinement fusion (ICF) diagnostics play a crucial role in understanding the complex physical processes governing ICF and enabling ignition. During the ICF process, the interaction between the high-power laser and ablation material

Defining Composition–Cytokine Relationships Enables the Design of Lipid Nanoparticles with Programmed Immunogenicity

Small, EarlyView.
Lipid nanoparticle composition governs distinct cytokine programs through the interplay of ionizable and polyethylene glycol‐conjugated (PEGylated) lipids. In vitro profiling, design of experiments (DoE) modeling, and in vivo validation reveal how formulation can tune reactogenicity‐associated pathways, while transgene expression remains the strongest ...
