  • Patent number: 10781304
    Abstract: Polypropylene composition comprising (A) 60 to 95 wt % of a heterophasic polypropylene (HECO) comprising 10 to 30 wt % of dispersed phase with the dispersed phase having a comonomer content of 30 to 45 wt % and the HECO having a melt flow rate MFRPP in the range of 12 to 200 g/10 min and being prepared in the presence of a Ziegler Natta catalyst (ZN-C), (B) 0 to 15 wt % of one or more elastomers, (C) 5 to 20 wt % of at least one filler wherein the polypropylene composition fulfils inequation (1) fogging?0.02 MFRComp+0.3. The composition allows for a well-balanced combination of a good impact/stiffness balance, a good scratch resistance, low VOC and FOG emissions and remarkable good fogging values.

  • Publication number: 20200030455
    Abstract: The present invention primarily relates to a novel, flexible, modular, multi-step, targeted and conditional drug targeting and delivery system. This system bypasses some general limitations of Antibody Drug Conjugates (ADCs) and widens the applicability of these key anticancer agents in precision medicine.

  • Patent number: 4331709
    Abstract: Fast surface states in MOS devices, such as SCCDs, are reduced by depositing a relatively thin amorphous layer containing silicon and hydrogen onto the SiO.sub.2 surface of such devices and annealing the resultant device in a non-oxidizing atmosphere for brief periods of time at a temperature in excess of the deposition temperature for the amorphous layer but below about 500.degree. C. so that free valences at the Si-SiO.sub.2 interface region are saturated with hydrogen. Surface state densities of about 4.times.10.sup.8 cm.sup.-2 eV.sup.-1 and SCCDs having .epsilon.=1.10.sup.-5 can be achieved via this process. The process is useful in producing SCCDs with low surface state densities and other MOS devices having low surface generated dark currents.
