Effect of thermal annealing on an emissive layer containing a blend of a small molecule and polymer as host for application in OLEDs.

In order to improve the performance of OLEDs, a host-guest mixture was used as an emissive layer. To have better host properties, a mixture of different materials with suitable properties can also be used as a host. In this study, we used a mixture of a polymer and a small molecule as the host and studied the effect of thermal annealing on the emissive layer properties by using Ir(ppy) as the emitter.

Detection of bacterial contaminants via frequency manipulation of amino-groups functionalized FeOnanoparticles based resonant sensor.

Bacterial infections have a large impact on public health. Through this study, we report on the development of complementary split-ring resonators (CSRR) supplemented by functionalized nanoparticles to detect bacteria in the aqueous medium. Iron oxide (FeO) nanoparticles were functionalized with amino groups using (3-aminopropyl) triethoxysilane (APTES) to form (APTES@FeO) nanoparticles, which have a specific affinity towards the bacterial species.

Cervical Lymph Node Evaluation in Oral Squamous Cell Carcinoma Patients Using Ultrasound-Guided Fine-Needle Aspiration Cytology - A Descriptive Diagnostic Evaluation Study in a Tertiary Care Center.

Background: Oral cancer is the most frequent type of cancer of the head and neck area, with squamous cell carcinoma (SCC) being the most common single entity. Worldwide, oral cancer accounts for 2%-4% of all cancer cases, the prevalence being highest in India. Lymph node metastases occur in about 40% of patients with oral cancer.

Comparative evaluation of platelet-rich fibrin, platelet-rich fibrin + 50 wt% nanohydroxyapatite, platelet-rich fibrin + 50 wt% dentin chips on odontoblastic differentiation - An study-part 2.

Aim: The purpose of this study was to investigate the effects of platelet-rich fibrin (PRF) modified with bioactive radiopacifiers-nanohydroxyapatite (nHA) and dentin chips (DC) on odontoblastic differentiation in human dental pulp cells (HDPCs).

Subjects And Methods: PRF was modified with 50wt% of nHA (G bone-SHAG31, Surgiwear Company) and 50 wt% of DC. HDPSCs differentiation and mineralization by the groups ([Group A - Control (Dimethyl sulfoxide), Group B - PRF, Group C - PRF + nHA, Group D - PRF + DC]) were assessed.

Efficient and tunable shape selective synthesis of Ag/CeO nanostructures modified highly stable SERS substrate for ultrasensitive detection of pesticides on the surface of an apple.

Detection of pesticide residues from fruits and vegetables is of significant importance to ensuring human health and environmental safety. An efficient and tunable shape-selective synthesis of Ag/CeO nanostructures as an active flexible SERS substrate for the detection of thiram on an apple surface a paste, peel off, and paste again process was performed. The well-controlled formation of silver assembled CeO microspheres constituting nanospheres and nanospindles with an average size of approximately 56 and 32 nm with anisotropic structures has been confirmed through morphological and crystallographic analysis.
