The preparation of a highly ordered nanostructured transparent electrode based on a combination of nanosphere lithography and anodization is presented. The size of perfectly ordered pore domains is improved by an order of magnitude with respect to the state of the art. The concomitantly reduced density of defect pores increases the fraction of pores that are in good electrical contact with the underlying transparent conductive substrate. This improvement in structural quality translates directly and linearly into an improved performance of energy conversion devices built from such electrodes in a linear manner.

Titanium dioxide (TiO) thin films were deposited on glass substrates under HV conditions at room temperature by the physical vapor deposition method. Produced titanium thin films were post-annealed at 573 K at different oxygen flows (0, 9 and 23 cm/s). The influence of different oxygen flows on nano-structure, crystallography, and optical parameters of TiO films was investigated by XRD, AFM, and spectrophotometer in the UV-VIS wavelength range.

Passive daytime radiative cooling (PDRC) offers a sustainable solution to global energy challenges by dissipating heat without energy input. However, conventional PDRC materials face trade-offs between biodegradability, color integration, optical transparency, and mechanical robustness. Herein, a biomimetic, structurally colored PDRC film fabricated via evaporation-induced self-assembly of cellulose nanocrystals (CNCs), betaine, and polyvinyl alcohol was developed.

The development of "smart" polymers capable of responding to physiologically relevant stimuli is essential for engineering dynamic sensing and actuation systems that leverage biological signals under specific (patho)physiological conditions. In this study, we present a general and versatile strategy to engineer novel stimuli-responsive behaviors in temperature-responsive protein-based polymers (PBPs) site-specific conjugation with self-immolative molecules. Specifically, we developed hydrogen peroxide (HO)- and β-galactosidase (β-gal)-responsive elastin-like polypeptides (ELPs) and resilin-like polypeptides (RLPs).

DNA origami-based nanotechnology is a versatile tool for exploring fundamental biological questions and holds significant promise for future biomedical applications. Here, we leverage the optical transparency of the embryonic zebrafish to analyze live embryos injected intravenously with fluorescently labeled wireframe DNA origami nanosheets. Our approach integrated long-term, high-resolution imaging of transgenic live zebrafish embryos with single-cell RNA sequencing to elucidate the effects of oligolysine-polyethylene glycol copolymer (K-PEG) coating on the biodistribution of fluorescence signal in embryos injected with wireframe DNA origami nanosheets.

Background: The transparent jellyfish body is often difficult to see underwater, as its refractive index is similar to that of seawater, resulting in a low light reflectance on the body surface. Nevertheless, the outlines of jellyfish can be recognized by the slight reflection of light from their body surfaces. In some jellyfish species, the epidermis covering the body surface has an array of microvilli, nanostructures that can potentially reduce light reflection.
