Flexible Polypyrrole‐Based pH Sensors via Oxidative Chemical Vapor Deposition

open access: yesAdvanced Healthcare Materials, EarlyView.
Oxidative chemical vapor deposition (oCVD) of polypyrrole (PPy) thin films yields flexible, electrically conductive, and biocompatible pH sensors for monitoring on‐skin biological events. The highly sensitive, oCVD PPy skin‐conformal sensors enable real‐time, spatially resolved sensing of dynamic pH changes within physiologically relevant ranges (4–9 ...

Evaluating Drought Vulnerability of Small Community Surface Water Supply Systems in the Midwest [PDF]

open access: yes, 2009
This report presents approaches and data availability for evaluating the drought vulnerability of small community water supply systems in the Midwest that obtain water from surface water bodies, such as rivers, streams, natural lakes, and man-made ...

Meteorological Factors Affecting Pan Evaporation in the Haihe River Basin, China

open access: yesWater, 2019
Pan evaporation (Epan) is an important indicator of regional evaporation intensity and degree of drought. However, although more evaporation is expected under rising temperatures, the reverse trend has been observed in many parts of the world, known as ...

Electro‐Stimulated Graphene‐Polymer Nanocomposites Enable Wearable Patches With Feedback‐Controlled Drug Release

open access: yesAdvanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Stimuli‐responsive nanomaterials capable of spatiotemporal control over drug release are of nanocomposite patch (“e‐Medi‐Patch”) engineered from biodegradable polycaprolactone (PCL), graphene nanoplatelets, and a redox‐active therapeutic, niclosamide. The hierarchical composite integrates π‐π interactions between aromatic drug molecules

The blue water footprint of electricity from hydropower [PDF]

open access: yes, 2012
Hydropower accounts for about 16% of the world's electricity supply. It has been debated whether hydroelectric generation is merely an in-stream water user or whether it also consumes water.

Pan evaporation modeling in different agroclimatic zones using functional link artificial neural network

open access: yes, 2020
Pan evaporation is an important climatic variable for developing efficient water resource management strategies. In the past, many machine learning models are reported in the literature for pan evaporation modeling using the different combinationof ...

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

open access: yesAdvanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Measurement of Evaporation from Salt Water Pan

open access: yesPapers in Meteorology and Geophysics, 1980
信頼できる蒸発量の測定は気象をはじめ、多くの科学分野で重要である。世界の気象観測業務では一日間の蒸発量をクラスAパンなどの大型蒸発計を使って測定しているところが多い。この場合、蒸発量は皿の中の水深をフックゲージで測定して求めている。そのため、風が測定に影響を及ぼすし、とくに短時間の少ない蒸発量はこの方法では求めることは出来ない。 最近、塩分測定技術が電気伝導度法を用いることによって改良され、0.003‰の精度で塩分濃度を測定できるようになった。そこで電気伝導度法を用いた塩分測定技術を応用して短時間の蒸発量でも正確に測定し得る方法をここで提案する。この方法の検討結果は以下の通りである。 この方法による蒸発量測定の相対誤差は約2.5%以下にすることができる。標本抽出誤差は4×10-4‰以下であり ...
