The use of hemp as a forage source in livestock diets has been less studied because bioactive residues in animal tissues may pose a risk to consumers. This study investigated the effects of partial substitution of alfalfa hay(AH) with hemp forage(HF) in growing goat diets on growth performance, carcass traits, ruminal fermentation characteristics, rumen microbial communities, blood biochemistry, and antioxidant *** Xiangdong black goats with body weight(BW) 7.82 ± 0.57 kg(mean ± SD) were grouped by BW and randomly assigned into one of the four treatment diets(n = 10/treatment) in a completely randomized design. The goats were fed ad libitum total mixed rations containing 60% forage and 40% concentrate(DM basis). The diets included control(CON; 60% AH and 40% concentrate), 55% AH and 5% HF(HF5), 50% AH and10% HF(HF10), and 40% AH and 20% HF(HF20). Increasing the substitution of HF for AH linearly decreased(P = 0.004) DM intake and improved feed conversion efficiency. However, final BW, average daily gain,carcass traits, meat quality, and most blood biochemistry indices did not differ among treatments. The ruminal NH3-N concentration(P = 0.003) and blood urine nitrogen(P = 0.050) linearly increased(P < 0.01)with increasing substitution rate of HF, whereas the total volatile fatty acids concentration quadratically changed(P = 0.007). Substitution of AH with HF had no effect on the diversity and richness of ruminal microbes, though it linearly decreased(P = 0.040) Prevotella＿1 and linearly increased(P = 0.017) Rikenellaceae＿RC9＿gut＿group. The cannabinoids and/or their metabolites were detected in both ruminal filtrates(8) and plasma(4), however, no detectable cannabinoid-related residues were observed in *** results indicate that the HF could be used to partially substitute AH in goat diets, whereas the effects vary between substitution rates of HF for AH. Although no cannabinoid-related residues were detected in meat, the presence of cannabinoids resid

Polaron interfacial entropy as a route to high thermoelectric performance in DAE-doped PEDOT:PSS films

Enhancing the thermoelectric transport properties of conductive polymer materials has been a long-term challenge, in spite of the success seen with molecular doping strategies. However, the strong coupling between the thermopower and the electrical conductivity limits thermoelectric performance. Here, we use polaron interfacial occupied entropy engineering to break through this intercoupling for a PEDOT:PSS(poly（3,4-ethylenedioxythiophene）-poly（4-styrenesulfonate）) thin film by using photochromic diarylethene（DAE） dopants coupled with UV-light modulation. With a 10-fold enhancement of the thermopower from 13.5 μV K-1to 135.4 μV K-1and almost unchanged electrical conductivity, the DAE-doped PEDOT:PSS thin film achieved an extremely high power factor of 521.28 μW m-1K-2from an original value of 6.78 μW m-1K-2. The thermopower was positively correlated with the UV-light intensity but decreased with increasing temperature, indicating resonant coupling between the planar closed DAE molecule and PEDOT. Both the experiments and theoretical calculations consistently confirmed the formation of an interface state due to this resonant coupling. Interfacial entropy engineering of polarons could play a critical role in enhancing the thermoelectric performance of the organic film.
