Chemistry of PCBs and PBBs [PDF]
Environmental Health Perspectives, 1978 A recent book by Hutzinger et al. (1) reviews the chemistry of chlorinated biphenyls through the end of 1973. This wide-ranging review also includes discussions of metabolism and determination of chlorinated biphenyls. The present report reviews areas of chlorobiphenyl and bromobiphenyl chemistry held to be pertinent to the Subcommittee's concern for ...

Multilayered Digital Microfluidic Chip for Cell‐Based Assays
Advanced Materials Interfaces, EarlyView.A multilayered digital microfluidic (mDMF) chip architecture is introduced to improve throughput and robustness in cell‐based assays. By multilayering electrode components and dielectric layers on glass, this design significantly reduces actuation voltage, maintains reliability, and enables expansion of the operational area with minimum current leakage.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes
Advanced Materials Technologies, EarlyView.We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Journal of Japan Association on Odor Environment, 2005 八王子市の小学校で起こったPCB含有蛍光灯安定器の破裂事故を契機にPCBの「におい」を認識した．実際に30年程度使用されてきた蛍光灯安定器から，PCBのにおいを感じた．そこで，劣化したPCB含有安定器からPCBが揮発する可能性を明らかにするため，PCB含有安定器を使用している室内と使用していない室内に含まれるPCBを測定し，比較するとともに，PCB含有安定器をチャンバーに入れて通気し，PCB揮発の有無を確かめた．その結果，PCB含有安定器を使用していない室内の空気ではPCBは検出されなかったのに対し，PCB含有安定器を使用している室内では26～110ng/m3のPCBが検出された．これより，PCB含有安定器からのPCBの漏洩の可能性が確認された．一方，チャンバー実験からは ...
