Prominent platforms based on thin-film lithium niobate (TFLN) are superior integrated-photonics platforms for efficient optical parametric amplification (OPA), however, previously few studies have been systematically reported the gain-boosting performance of TFLN waveguides compared to bulk LN waveguides. Here, we optimize two TFLN waveguides with dispersion engineering for high-efficiency and ultra-broadband gain of OPA, then report comparative results about the efficient ultra-broadband OPA of TFLN waveguides in the case of low loss, optimized waveguide length and pump power. Note that the efficient ultra-broadband OPA of TFLN waveguides is represented by the peak gain (71.

Background: Dietary supplementation for beef cattle, using natural plant extracts, such as oregano essential oil (OEO), has proven effective in enhancing growth performance, beef production quantity and quality, and ensuring food safety. However, the precise mechanisms underlying these effects remain unclear. This study investigated the impact of OEO on carcass traits, muscle fiber structure, meat quality, oxidative status, flavor compounds, and gene regulatory mechanisms in the longissimus thoracis (LT) muscles of beef cattle.

Conjugated polymer donors have always been one of the important components of organic solar cells (OSCs), particularly those featuring simple synthetic routes, proper energy levels, and appropriate aggregation behavior. In this work, we employed a nonfused electron-deficient building block, dicyanobithiophene (2CT), for constructing high-performance donors. Combining this with side-chain engineering, two novel halogen-free polymer donors, PB2CT-BO and PB2CT-HD, were reported.

Carbon-based perovskite solar cells (C-PSCs) have the advantages of high stability and low cost, but their mean efficiency has become an obstacle to commercialization. Defects, which are widely distributed on the surface and bulk of films, are an important factor in C-PSCs for low efficiency. The conventional post-treatment method through forming a low-dimensional (LD) perovskite layer usually fails in manipulating the bulk defects.

Morphology control plays a key role for improving efficiency and stability of bulk heterojunctions (BHJ) organic solar cells (OSCs). Halogenation and methoxylation are two separate ways successfully adopted in additives for morphology optimization. In this work, these two strategies are combined together.
