A typical glucose sensor is a oxidase (GOx) enzyme-based due to its high sensitivity and selectivity. However, it has difficulty activating stabilizing the enzyme. To enhance stability of GOx-based sensors, chitosan added ZnS-doped Mn nanoparticles. Chitosan stabilizes particles can induce charge processes such as creation, transfer, separation at polymer interface nanoparticles' interface. Hen...
This paper reports on durable and nearly temperature-independent (at 298-328 K) T-type photochromism of colloidal Cu-doped ZnS nanocrystals (NCs). The color NC powder changes from pale yellow to dark gray by UV light irradiation, the back a time scale several tens seconds minutes after stopping while decoloration reaction is accelerated submillisecond in solutions. much faster than those conven...
Photoluminescence (PL) of zinc sulfide powder synthesized and doped with Mn 2+ Eu 3+ ions by the method emerging reagents in a dodecane medium was investigated. In absorption excitation spectra PL samples ZnS : (Eu ), bands corresponding to transitions electrons from valence band conduction levels structural defects ZnS, as well transition 4f-electrons ground 7 F 0 excited electronic states wer...
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...
