Manganese ions (Mn2+)-coordinated nanoparticles have emerged as a promising class of antitumor nanotherapeutics, capable simultaneously disrupting the immunosuppressive tumor microenvironment (TME) and triggering stimulator interferon genes (STING) pathway-dependent immunity. However, activation STING signaling by Mn2+-based monotherapies is suboptimal for comprehensive stimulation antigen presenting cells reversal immunosuppression in TME. Here, we report design Mn2+/CpG...
Interest in biomedical terahertz research is growing rapidly and there are now several groups Asia, Europe the US investigating potential applications such as pharmaceutical quality control, protein characterization cancer detection. This review article outlines technological bottlenecks that have been overcome which made possible. Key findings will be presented, limitations remain initiatives strive to address them also discussed.
The realization of high-performance tunable absorbers for terahertz frequencies is crucial advancing applications such as single-pixel imaging and spectroscopy. Based on the strong position sensitivity metamaterials' electromagnetic response, we combine meta-atoms that support strongly localized modes with suspended flat membranes can be driven electrostatically. This design maximizes tunability range small mechanical displacements membranes. We employ a micro-electro-mechanical system...
Abstract Chiral metasurfaces with pronounced reflective chiroptical responses have drawn extensive attention as they can offer great opportunities for various chirality‐related applications. However, their fascinating potential are restrained by limited responses, relatively complex design principle, and fabrication strategy. Herein, a concise general principle to develop out‐of‐plane chiral metasurfaces, empowered the maximum theoretical circular dichroism (CD), is theoretically proposed...
We use terahertz imaging to measure four human skin scars in vivo . Clear contrast between the refractive index of scar and surrounding tissue was observed for all scars, despite some being difficult see with naked eye. Additionally, we monitored healing process a hypertrophic scar. found that absorption coefficient became less prominent after few months post‐injury, but still significant even post‐injury. Our results demonstrate capability quantitatively subtle changes properties this may...
Nowadays, the practical applications of metal–organic framework (MOF)-based fluorescence detectors are severely hindered because complex synthesis process linkers or heavy metal contamination. The development a simple, inexpensive, and environmentally friendly sensing system remains huge challenge. In this study, we designed synthesized TPE@γ-CD-MOF-K using facile in situ encapsulation method. unique pore structure γ-CD-MOF allowed it to effectively include TPE explosives as guests...
Layer-structured black phosphorus (BP) demonstrating high specific capacity has been viewed as a very promising anode material for future high-energy-density Li-ion batteries (LIBs). However, its practical application is hindered by large volume change of BP and poor mechanical stability anodes traditional slurry casting technology. Here, free-standing flexible composed nanosheets nanocellulose (NC) nanowires fabricated via facile vacuum-assisted filtration approach. The constructed BP@NC...
Layered metal oxide cathodes suffer from a low specific capacity (below 200 mAh g–1), while long-term retention is limited by electrolyte decomposition at high voltage (>4.5 V), decohesion, and fracture in primary grains upon cycling. Here, LiNi0.5Co0.2Mn0.3O2 (NCM523) 4.8 V, employing p-toluenesulfonyl isocyanate (PTSI) as an additive, has been investigated, which shows much improved cycling capabilities rate performances for when cell of V applied. On the basis electrochemical analysis...
Terahertz (THz) topological photonic structures are promising for last-centimeter communication in intra/interchip systems because they support bit-error-free THz signal transmission with robustness. Active and dynamically tunable components have not yet been experimentally realized. Here, we demonstrate a switch (270–290 GHz) based on valley Hall crystal structured high-resistivity silicon substrate, which the waves can be turned on/off by an external 447 nm continuous-wave laser. Our...

Abstract Waveguide tapers are seemingly indispensable elements in silicon photonics that usually operate adiabatically to maximize the coupling efficiency between waveguides with different cross‐sections, which, however, necessitate large footprints. To date, great efforts have been made minimize tapers’ footprints while maintaining their efficiency. Contrary conventional wisdom, here, a concept of taper‐free is proposed which cross‐sections couple each other efficiently without using...
Sample dehydration has traditionally been a challenging problem in ex vivo terahertz biomedical experiments as water content changes significantly affect the properties and can diminish important contrast features. In this paper, we propose novel method to prevent sample using gelatin embedding. By looking at image data calculating optical of gelatin-embedded sample, find that our successfully preserves for least 35 h, both imaging spectroscopy. Our preservation demonstrates first time...

Mixed matrix membranes (MMMs) for CO2 separation have overcome the trade-off between gas permeability and selectivity to some extent. However, most MMMs still are prepared in lab- pilot-scales since of not good enough reach economically available requirements. Moreover, fabrication few with performance is time-consuming or need harsh conditions. In this study, a novel MOF-based composite membrane (PAN-γ-CD-MOF-PU membrane) was successfully fabricated by facile fast spin-coating method....
