Optical properties of highly ordered Ge nanopillar arrays are tuned through shape and geometry control to achieve the optimal absorption efficiency. Increasing materials filling ratio is shown increase reflectance while simultaneously decreasing transmittance, with absorbance showing a strong diameter dependency. To enhance broad band optical efficiency, novel dual-diameter structure presented, small tip for minimal large base maximal effective coefficient. The enabled single-crystalline...
Metal-catalyzed crystallization of amorphous carbon to graphene by thermal annealing is demonstrated. In this “limited source” process scheme, the thickness precipitated directly controlled initial layer. This in contrast chemical vapor deposition processes, where source virtually unlimited and controlling number layers depends on tight control over a parameters. Based Raman analysis, quality comparable other synthesis methods found literature, such as deposition. The ability synthesize...
Direct application of benzyl alcohols (or their magnesium salts) as electrophiles in various reactions with Grignard reagents has been developed via transition metal-catalyzed sp(3) C-O bond activation. Ni complex was found to be an efficient catalyst for the first direct cross coupling aryl/alkyl reagents, while Fe, Co, or catalysts could promote unprecedented conversion presence (n)hexylMgCl. These methods offer straightforward pathways transform into a variety functionalities.
Abstract Stimulus‐responsive drug release possesses considerable significance in cancer therapy. This work reports an upconversion‐luminescence‐fueled DNA–azobenzene nanopump for rapid and efficient release. The is constructed by assembling the azobenzene‐functionalized DNA strands on upconversion nanoparticles (UCNPs). Doxorubicin (DOX) loaded intercalation helix. Under NIR light, UCNPs emit both UV visible photons to fuel continuous photoisomerization of azo, which acts as impeller pump...

This method features mild reaction conditions, high selectivity, good functional group tolerance, wide substrate scope, easy scalability.
Abstract Tumor response to radiotherapy or ferroptosis is closely related hydroxyl radical (•OH) production. Noninvasive imaging of •OH fluctuation in tumors can allow early monitoring therapy, but challenging.

The displays large FL ratio between 780 1113 nm (FL /FL ), small PA 755...
Taking advantage of cancer cells' endogenous characters, the responsive activation DNA nanomachines has achieved great success in tumor therapy. Combining with extra stimuli such as external light irradiation provided spatiotemporal control nanomachine activation. However, specific at cellular level is still challenging considering macroscopic-scale exposure area usual sources. logic gates located cell membrane contributed to specificity, but free diffusion input strands during operation...

A high catalytic efficiency associated with a robust chemical structure are among the ultimate goals when developing new biocatalytic systems for biosensing applications. To get ever closer to these goals, we report here on combination of metal–organic framework (MOF)-based nanozymes and G-quadruplex (G4)-based system known as G4-DNAzyme. This approach aims at combining advantages both partners (chiefly, robustness former modularity latter). this end, used MIL-53(Fe) MOF linked it covalently...
Cytoplasmic male sterility (CMS) determined by mitochondrial genes and restorer of fertility ( Rf ) controlled nuclear-encoded provide the breeding systems many hybrid crops for utilization heterosis.
