Background: International research and innovation efforts for neglected tropical diseases have increased in recent decades due to disparities in overall health research funding in relation to global burden of disease. However, within the field of neglected tropical diseases some seem far more neglected than others. In this research the aim is to investigate the distribution of resources and efforts, as well as the mechanisms that underpin funding allocation for neglected tropical diseases. methodology: A systematic literature review was conducted to establish a comprehensive overview of known indicators for innovation efforts related to a wide range of neglected tropical diseases. Articles were selected based on a subjective evaluation of their relevance, the presence of original data, and the breadth of their scope. This was followed by thirteen in-depth open-ended interviews with representatives of private, public and philanthropic funding organizations, concerning evaluation criteria for funding research proposals. Results: The findings reveal a large difference in the extent to which the individual diseases are neglected with notable differences between absolute and relative efforts. Criteria used in the evaluation of research proposals relate to potential impact, the probability of success and strategic fit. Private organizations prioritize strategic fit and economic impact;philanthropic organizations prioritize short-term societal impact;and public generally prioritize the probability of success by accounting for follow-up funding and involvement of industry. Funding decisions of different types of organizations are highly interrelated. Conclusions: This study shows that the evaluation of funding proposals introduces and retains unequal funding distribution, reinforcing the relative neglect of diseases. Societal impact is the primary rationale for funding but application of it as a funding criterion is associated with significant challenges. Furthermore, curre

采用一锅法将生物柴油副产物粗甘油(CG)转化为生物基多元醇(CG-polyol),并以糠醛渣(FR)为增强填料,共混发泡制备出一种FR增强生物基聚氨酯(PU/FR)泡沫复合材料。通过对PU/FR泡沫的结构形貌、热稳定性、发泡时间、密度和压缩强度进行表征,探究了糠醛渣粒径(0.25 mm、 0.09 mm样品分别标记为FR60和FR180)和添加量对PU/FR泡沫性能的影响。结果表明:通过热转化法合成的CG-polyol酸值为1.9 mg/g、羟值为406 mg/g、黏度为1 092 mPa·s,该多元醇适合用于制备PU泡沫。FR的加入延长了发泡时间,最大上升时间和不粘时间分别由未添加时的29和31 s提高到37和39 s,泡孔结构更加完整,泡孔尺寸减少,破碎现象明显减少。FR添加量≤5%时,可有效提高泡沫的密度和压缩强度;当添加量相同时,FR180填料对泡沫的性能提升更显著;当FR180添加量为5%时制备的PU/FR180-5泡沫复合材料的压缩强度达到最大为0.153 3 mPa,相比未添加FR的泡沫提高了28.1%,此时密度为0.051 0 g/cm~3,导热系数为0.032 8 W/(m·K),复合材料的综合性能较好。同时FR的添加可适当提高PU泡沫材料的热稳定性,相比未添加FR的泡沫的最大热解速率温度(T_(max))453℃,PU/FR180-5泡沫的T_(max)达到463℃。
