Abstract

We propose a quantum algorithm to solve systems of nonlinear algebraic equations. In the ideal case the complexity of the algorithm is linear in the number of variables $n$, which means our algorithm's complexity is less than $O(n^{3})$ of the corresponding classical ones when the set of equations has many variables and not so high orders. Different with most popular way of representing the results by state vector, we get the results in computation basis which is readable directly.

Abstract

Photothermal materials often prioritize solar absorption while neglecting thermal radiation losses, which diminishes thermal radiation conversion efficiency. This study addresses this gap by introducing a germanium (Ge) subwavelength structure (SWS) designed to optimize both solar absorption and infrared emissivity. Using a self-masked reactive ion etching (RIE) technique, we achieved a peak absorption of 98.8% within the 300 nm to 1800 nm range, with an infrared emissivity as low as 0.32. Under solar illumination of 1000 W/m2, the structure's temperature increased by 50 °C, generating a heating power of 800 W/m2. Additionally, it demonstrated good mechanical and thermal stability at high temperatures and possessed a hydrophobic angle of 132°, ensuring effective self-cleaning. These characteristics make the Ge SWS suitable for application in solar panels, displays, sensors, and other optoelectronic devices. [ABSTRACT FROM AUTHOR]

Abstract

Lipid nanoparticles (LNPs) have been demonstrated to be potent and well‐tolerated vehicles for delivering mRNA in vaccination and therapeutics. However, the presence of anti‐poly(ethylene glycol) (PEG) antibodies in the body resulted in the problems of hypersensitivity reaction, accelerated blood clearance and high systemic reactogenicity after repeated dosing of PEG lipid‐contained LNPs, thus limiting the utility for in vivo messenger RNA (mRNA) delivery. Here, we synthesized well‐defined polysarcosine functionalized lipids (pSar‐lipids) with various hydrophobic tail lengths and molecular weights by the accelerated ring‐opening polymerization of sarcosine N‐carboxyanhydride (NCA). The obtained pSar‐lipids were utilized as PEG lipid alternatives to explore structure–activity relationships of pSar‐lipid‐based LNPs. The results demonstrated that pSar‐lipid‐based LNPs by intravenous administration represented higher mRNA delivery efficiency in the liver and spleen with the increased hydrophobic tail length of pSar‐lipids. Importantly, more significant preference for mRNA delivery into the liver was identified by increasing the molecular weight of pSar segments. As a result, this work elucidated the effect of structural variations in pSar‐lipids on LNP‐mediated in vivo mRNA delivery, providing clues to optimize pSar‐lipids as potential alternatives to PEG lipids for developing next‐generation of LNP delivery systems.
