Synthetic Nanobiology Actuated Lipometabolic Cell Factory for Autologous Tumor Immunotherapy

Advanced Functional Materials, EarlyView.
FA plays a crucial role in the interaction between tumor cells and the tumor microenvironment, especially for the immune response. A biocatalytic immunoenhancement strategy is developed to boost antitumor immunity by FA metabolic orientation to ceramide. Through the design of this delicate catalytic immunoenhancement strategy, the synthetic nanobiology

Dual‐Polarization Phased Array Radar Observations of Quasi‐Linear Convective System Tornadic Mesovortices

Geophysical Research Letters
Quasi‐linear convective system (QLCS) mesovortices produce a non‐trivial fraction of tornadoes across the United States each year. Tornadoes from QLCS mesovortices evolve rapidly on time scales less than that observed by conventional weather radars.

Germanane Quantum Dots Promote Metabolic Reprogramming of Immune Cells Toward Regulatory T Cells and Suppress Inflammation In Vitro and In Vivo

Advanced Functional Materials, EarlyView.
Metabolic changes in immune cells direct the phenotype and function of the host immune system. Smart nanomaterials must target metabolic pathways to direct immune cell fate. This study reports the fabrication and first application of germanane quantum dots (GeHQDs) to modulate inflammation in vitro and in vivo.

Impact of Surface Functionalization on NV Quantum Properties: Implications for Biosensing with Fluorescent Nanodiamonds

Advanced Functional Materials, EarlyView.
Fluorescent nanodiamonds (fNDs) have emerged as an invaluable quantum sensing platform for biological and biochemical systems. This paper investigates the influence of common surface functionalization strategies for bioconjugation on the quantum properties of nitrogen vacancy (NV) centers in nanodiamonds.

Dual Polarized Dual Coverage Reflectarray-Based Passive Reflecting Surface for Next-Generation Networks

IEEE Open Journal of Antennas and Propagation
A single-layer reflectarray configuration is investigated for dual-polarization operation at 5G millimeter wave (mmWave) frequencies. The proposed reflectarray cell is designed as a viable solution for passive reflecting surfaces to enhance 5G network ...

The Effect of Purcell Cavities on the Lifetime of Thermally Activated Delayed Fluorescent Emitters

Advanced Functional Materials, EarlyView.
A pressing challenge to OLED displays and lighting is to balance high efficiency and long operational lifetime in the deep blue spectrum. The Purcell effect can reduce the triplet density and hence the probability for destructive energy‐driven triplet annihilation events that limit the OLED lifetime. Here we study of the Purcell effect on two different
