2022 47th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz), 28 August 2022 - 02 September 2022; Delft, Netherlands.-- Research conducted in the framework of MIRACLE Project (Photonic Metaconcrete with Infrared RAdiative Cooling capacity for Large Energy savings, GA 964450), coordinated by Dr. Jorge Sánchez Dolado, from Centro de Física de Materiales (CFM)., Two periodic structures composed of metal cylinders with different orientations are used to improve the solar reflection of calcium silicate hydrate (CSH) while maintaining its atmospheric emission. Interesting effects have been found when the distance between bars is small, suggesting that lattice effects, arising from the interaction between the rods could be leveraged in the design of these metamaterials. The size of the metal bars is selected based on state of the art micro-manufacturing techniques. This study limits its scope to a CSH gel model; i.e. the most important component of cement-based materials. Further research will be undertaken to consider a best description of the dielectric function of concrete., This work has been funded by the research and innovation program Horizon 2020 of the European union.

XXXVI Simposium Nacional de la Unión Científica Internacional de Radio, URSI 2021, Vigo, Spain (online), 20-25 Sep. 2021.-- Research conducted in the framework of MIRACLE Project (Photonic Metaconcrete with Infrared RAdiative Cooling capacity for Large Energy savings, GA 964450), coordinated by Dr. Jorge Sánchez Dolado, from Centro de Física de Materiales (CFM)., In this work, a study of the viability of using concrete for radiative cooling is done by theoretically analysing some of the main compounds of concrete: C3S, CH and CSH. Atomistic simulations have been employed for determining the structure and the dielectric response of these phases. Interestingly, the materials have theoretically shown a night-time net cooling power of 55.68 W, 60.96 W and 62.43 W respectively. This preliminary study shows the potential of concrete as a possible cheap, scalable and widely used night-time radiative cooling structural material. Further research must be done in order to achieve a higher reflection in the solar band for day-time radiative cooling. To calculate de emissivity of the compounds, an analytical model has been used, which has nearly zero error and computes the data much faster than a simulator., Este trabajo ha recibido financiación del programa de investigación e innovación Horizonte 2020 de la Unión Europea, proyecto MIRACLE, Grant Agreement 964450.

背景 在欧洲和中国进行Elecsys®胃泌素释放肽前体（ProGRP）免疫检测的多中心评估研究。方法 在欧洲的3个中心和中国的2个中心，在肺癌中，通过不精密度、稳定性、方法学比较和鉴别诊断能力来评价该检测法。结果 5个分析物浓度的中间不精密度范围为变异系数：2.2%-6.0%。在不同储存条件下，血浆和血清样本均显示出良好的稳定性。在血浆中Elecsys®和ARCHITECT检测（斜率1.02，截距-2.72 pg/mL）之间表现出良好的相关性。同时，Elecsys®检测在血清和血浆样本之间表现出良好的相关性（斜率0.93，截距2.35 pg/mL；相关系数0.97）。ProGRP作为不受种族、年龄、性别或吸烟史相关影响的检测手段，可鉴别小细胞和非小细胞肺癌（NSCLC）；截断值为84 pg/mL时，曲线下面积为0.90，95%CI: 0.87-0.93；敏感性为78.3%，特异性为95%。ProGRP浓度中位数在良性病变（38 pg/mL）、其他恶性肿瘤（40 pg/mL）或NSCLC（39 pg/mL）中较低，而在3期以上慢性肾脏疾病中浓度较高（100 pg/mL）。结论 Elecsys® ProGRP检测在血清和血浆中稳定性增加，较现有检测法明显更具优势。ProGRP检测在中国的首次评价在不同种族中显示出相当的鉴别能力。.
