    • A system for use in forming polymer compositions, including as a replacement for phenolic based resin systems, for instance, in preparing foundry molds. In a preferred embodiment, the system includes the use of a) a polyermizable hydroxyl- containing component comprising a humic substance (as can be provided by lignite), b) an isocyanate component, and c) a catalyst, and preferably amine catalyst, component adapted to catalyze the polymerization of a) and b). The system is optionally used as binder system in the presence of a filler, such as, in combination with a foundry aggregate such as sand. A polymer system of this invention can be substantially free of formaldehyde or phenol, and preferably contains little or no aromatic solvents.
    • 用于形成聚合物组合物的系统,包括作为酚基树脂体系的替代物,例如在制备铸造模具中。 在优选的实施方案中,该系统包括以下用途:a)包含腐殖质(可由褐煤提供)的可多形成的含羟基成分,b)异氰酸酯组分,和c)催化剂,优选胺催化剂组分 适于催化a)和b)的聚合。 该系统任选地在填料存在下用作粘合剂体系,例如与诸如砂的铸造骨料组合使用。 本发明的聚合物体系可以基本上不含甲醛或苯酚,优选含有很少或不含芳族溶剂。

    • An apparatus and method for non-contact measurement, with nanometer precision, of surface properties such as the local slope and/or vibration amplitude of a solid material, or the surface tension of a small liquid sample. The apparatus provides a laser light source and optic transmission line adapted to be positioned above and near the sample surface, together with a mechanism adapted to move and/or vibrate or oscillate either the surface or probe, or both, with respect to each other. In turn, an interference pattern by the interaction of reflected light from the surface and light reflected by the terminus, that can be correlated to either: i) the amplitude of vibrations imparted to the surface, or ii) the local slope of the surface as determined in the course of controlled oscillation of the terminus.
    • 用于非接触测量的装置和方法,具有纳米精度的表面性质,例如固体材料的局部斜率和/或振幅,或小液体样品的表面张力。 该装置提供适于被定位在样品表面上方和附近的激光源和光学传输线,以及适于相对于彼此移动和/或振动或振动表面或探针或两者的机构。 反过来,来自表面的反射光和由终端反射的光的相互作用的干涉图案可以与以下相关:i)赋予表面的振动的振幅,或ii)表面的局部斜率, 在终点受控振荡的过程中确定。
