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 ...

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

Advanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Analog Tensor Processing With Carbon Nanotube In‐Memory Matrix Multiplications for Edge Computer Vision Acceleration

Advanced Materials, EarlyView.
This work prototypes a carbon nanotube‐based analog tensor core that performs in‐memory, parallel visual processing. Integrating non‐volatile memories and compact circuits, the core enables high‐speed analog matrix multiplications and can demonstrate accurate three dimensional (3D) spatial transformation and edge detection. With lightweight design, the

Volatilization of PCBs from PCB-containing Ballast in Fluorescent Lamp and Indoor PCB pollution: Odor of PCBs

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 ...

Efficient Hydroxyl Diffusion Triggers Surface Hydronium Enrichment and Bulk Proton Participation to Boost Alkaline Hydrogen‐Evolving Reaction

Advanced Materials, EarlyView.
For the first time, we shed light on the surface‐to‐bulk diffusion, induction, and reaction behaviors of OH−, H+, and H2O species on model oxides for alkaline hydrogen‐evolving reaction (HER). We first demonstrate that bulk OH− diffusion significantly affects the generation of proton sources and the diffusion/reaction behaviors of protons, thus ...
