Evaluation of Activated Carbon as a Reactive Cap Sorbent for Sequestration of PCBs in Presence of Humic Acid [PDF]

, 2009
This study investigated the interferences caused by high humic acid concentrations on the adsorption of coplanar and noncoplanar polychlorinated biphenyls (PCBs) on coconut shell activated carbon. In particular, the research focuses on the application of

Placental transfer of a hydroxylated polychlorinated biphenyl and effects on fetal and maternal thyroid hormone homeostasis in the rat [PDF]

, 2002
Earlier studies at our laboratory indicated that several hydroxylated polychlorinated biphenyls (OH-PCBs) detected in human blood could specifically inhibit thyroxine (T4) transport by competitive binding to the thyroid hormone transport protein ...

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

Advanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Sand to Root Transfer of PAHs and PCBs by Carrots Grown on Sand with Pure Substances and Biosolids Amended Sand [PDF]

, 2006
A study on behaviour of trace organic compounds (Polycyclic Aromatic Hydrocarbons, PAH, and Polychlorinated Biphenyls, PCB) in a sand-plant system has been carried out, with the reclamation of wastewater treatment plant biosolids for agriculture in mind.

Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines

Advanced Materials, EarlyView.
This study presented a liquid metal shape shifting strategy which harnesses Lorentz force, surface tension and fluid instabilities to achieve autonomous fluidic power. By using a liquid metal droplet as a mobile current carrier, this strategy enables the development of low‐voltage, self‐oscillating pumps that outperform existing soft pumps.

NUMERICAL MODELING OF THE FIELDS OF POLYCHLORINATED BIPHENYLS IN THE BLACK SEA

Geography, Environment, Sustainability, 2013
A mathematical three-dimensional model was developed by combining a physically complete block of circulation with modules of transport and transformation of detritus and polychlorinated biphenyls (PCBs).

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 ...

Probing Cellular Activity Via Charge‐Sensitive Quantum Nanoprobes

Advanced Materials, EarlyView.
A new quantum sensing modality detects shifts in zero‐field splitting caused by charge rearrangement with diamond nanocrystals in response to cellular activity. These electric‐field‐driven effects provide an alternative to temperature‐based interpretations, enabling real‐time, single‐cell readout of inflammation.
