Few Layer Graphene

In this paper, the sodium salt of styrene-maleic anhydride copolymer (SMA) was used as a stabilizer in the process of graphite exfoliation to few-layer graphene using the technique of microfluidization in water. This method is simple, scalable, and cost-effective, and it produces graphene at concentrations as high as 0.522 mg mL−1. The generated high-quality graphene consists of few-layer sheets with a uniform size of less than 1 μm. The obtained graphene was uniformly dispersed and tightly integrated into a polyamide 66 (PA66) matrix to create high-performance multifunctional polymer nanocomposites. The tensile strength and thermal conductivity of 0.3 and 0.5 wt% EG/PA66 composites were found to be ~32.6% and ~28.8% greater than the corresponding values calculated for pure PA66, respectively. This confirms that the new protocol of liquid phase exfoliation of graphite has excellent potential for use in the industrial-scale production of high-quality graphene for numerous applications.

Transgenic Goats

ABSTRACTTherapeutic monoclonal antibodies (mAbs) represent one of the most important classes of pharmaceutical proteins to treat human diseases. Most are produced in cultured mammalian cells which is expensive, limiting their availability. Goats, striking a good balance between a relatively short generation time and copious milk yield, present an alternative platform for the cost-effective, flexible, large-scale production of therapeutic mAbs. Here, we focused on cetuximab, a mAb against epidermal growth factor receptor, that is commercially produced under the brand name Erbitux and approved for anti-cancer treatments. We generated several transgenic goat lines that produce cetuximab in their milk. Two lines were selected for detailed characterization. Both showed stable genotypes and cetuximab production levels of up to 10g/L. The mAb could be readily purified and showed improved characteristics compared to Erbitux. The goat-produced cetuximab (gCetuximab) lacked a highly immunogenic epitope that is part of Erbitux. Moreover, it showed enhanced binding to CD16 and increased antibody-dependent cell-dependent cytotoxicity compared to Erbitux. This indicates that these goats produce an improved cetuximab version with the potential for enhanced effectiveness and better safety profile compared to treatments with Erbitux. In addition, our study validates transgenic goats as an excellent platform for large-scale production of therapeutic mAbs.

Embedded die substrate technologies are being developed in an assortment of configurations and for different market segments. The technology being discussed in this paper will be focused on both a fan out technology – ChipsetT Fan-Out and a system in package approach (ChipsetT SiP) in which a multiple component bill of materials (BOM) is used. The Chipset process is based on the WABE (Wafer and Board Level Embedding) technology. WABE technology is based on co-lamination of multilayer polyimide flex wiring and conductive z-axis sintered metal interconnections. This ChipsetT Fan Out technology allows for large scale production of fan out type solutions which can allow for very thin packages in addition to unique pin out solutions such as pin compatibility for a competitor part. The ChipsetT SiP also allows embedding of single or multiple silicon die and/or components. Additional components can also be placed using conventional SMT on the top or bottom side of the package. There is a great deal of design flexibility with this technology which makes it a great solution for applications trying to reduce their x-y size or z-height. When utilizing RDL technology on the embedded die we are able to do the fine pitch routing in order to allow the substrate to route at larger pitches ensuring an overall cost effective solution. This paper will focus on the different classes of applications that have benefited from this technology and will discuss the benefits and tradeoffs of the different solutions that have been engineered. Assembly and reliability data will be presented on several of the applications showing a robust solution set.
