In order to improve the quality and reduce the loss of the nutritional content of camellia oil with the traditional press, this paper studied the process of pressing Camellia Oleifera Seeds with 10t/d Twin-Screw Oil Press. The results demonstrated that the best conditions for this article were: 9% moisture content of Camellia Oleifera seed kernels and 8% content of Camellia oleifera seed shell. The oil content of Camellia oleifera seed cake was reduced to 2.49%, and the produced camellia oil could meet the standard of first -class oil. In comparison to the camellia oil sold on the market, the retention rate of α-tocopherol in the camellia oil obtained through this process was higher, and the nutritional value of camellia oil has been further improved, which could provide technical guidance for the high-value processing of camellia oil in China.

Efficient exciton dissociation at low energy offsets is key to overcoming voltage losses in organic solar cells. In this work, we developed two dimeric acceptors, i‐YT and o‐YT, by precisely controlling the position of an asymmetric electron‐donating linker. It induced the foldamer conformation of i‐YT with a para linkage (relative to the dicyano groups), while retaining the unfold conformation for o‐YT. This subtle structural modification influenced the molecular assembly properties, enabled near‐zero energy offset exciton dissociation and power conversion efficiencies exceeding 18 % for i‐YT based organic solar cells. Detailed excitonic dynamics further revealed that the linker position critically influences three processes: the formation of delocalized singlet excited states, ultrafast charge transfer (~5 ps) in solid blends, and the suppression of exciton recombination. Additionally, devices based on i‐YT demonstrated outstanding long‐term stability, retaining 85 % of their initial efficiency after 1,400 hours of continuous illumination. These findings introduce a new class of dimeric acceptors that combine high efficiency with exceptional stability, offering a promising pathway toward low‐energy‐loss organic photovoltaics.
