سابقه و هدف: شهرنشینی در جهان رو به افزایش است جمعیت شهری حال متراکم تر شدن شهرها می باشد. یکی از اثرات درصد سطوح نفوذ ناپذیر این مناطق امروزه بسیاری شهرهای مهم جهان، برای کاهش توسعه شهر خود بر کیفیت کمیت رواناب، مفهوم پایدار توجه نموده فنّاوری‌های مدرن سبز مدیریتی، شامل بهترین روش‌های مدیریتی با حداقل جانبی بهره می‌گیرند. بام سبز، یک سیستم چندلایه ای که سقف بالکن ساختمان را پوشش گیاهی پوشانده ج...

BACKGROUND We evaluated the Ziehl-Neelsen staining (ZNS) technique for the diagnosis of paragonimiasis in Laos and compared different modifications of the ZNS techniques. METHODOLOGY WE APPLIED THE FOLLOWING APPROACH: We (1) examined a paragonimiasis index case's sputum with wet film direct examination (WF) and ZNS; (2) re-examined stored ZNS slides from two provinces; (3) compared prospectiv...

Synthesis of ZnO/ZnS heterostructures under thermodynamic conditions generally results in the wurtzite (WZ) structure of the ZnS component because its WZ phase is thermodynamically more stable than its zinc blende (ZB) phase. In this report, we demonstrate for the first time the preparation of ZnO/ZnS coaxial nanocables composed of single crystalline ZB structured ZnS epitaxially grown on WZ Zn...

The effects of ZnS/Metal/ZnS multilayer anodes, including ZnS/Au/ZnS (ZAuZ), ZnS/Ag/ZnS (ZAgZ) and ZnS/Cu/ZnS (ZCuZ) on device performance in organic light emitting diodes based on rubrene were investigated systematically. The device with ZAuZ as anode gave an improved performance comparable with ITO based devices. A low driving voltage of 5.61 V and a high luminance of 1836 cd/m were obtained ...

We report a highly bright and stable aqueous dispersion of CuInS2/ZnS (CIS/ZnS) nanocrystals (NCs) using surfactant-assisted microemulsion and cold treatment. CIS/ZnS NCs were facilely synthesized via a stepwise, consecutive hybrid flow reactor approach. To stabilize the optical properties of hydrophobic CIS/ZnS NCs, cetyltrimethylammonium bromide (CTAB) was chosen as a matrix for aqueous phase...

O nanocompósito de partículas de ZnS estabilizadas por íons cetiltrimetilamônio (ZnS-CTA) e montmorilonita (ZnS−CTA−MMT) foi preparado e usado como catalisador na fotodecomposição de fenol sob radiação UV de uma lâmpada de Hg de pressão média. A quantidade de ZnS em ZnS−CTA−MMT foi aproximadamente 6 wt.%. Para comparação, a fotodecomposição foi também realizada com ZnS−CTA, montmorilonita e sem...

Zonisamide (ZNS), a commonly used anticonvulsant, scavenged hydroxyl radicals at a clinically relevant concentration. Reactants of ZNS with hydrogen peroxide and with hydrogen peroxide plus UV irradiation, yielding hydroxyl radicals, were analyzed by the LC/MS technique. Many small fragments were found in the both reactions, suggesting that ZNS was decomposed not only by hydroxyl radicals but a...
