Perovskite nickelates as bio-electronic interfaces.

Functional interfaces between electronics and biological matter are essential to diverse fields including health sciences and bio-engineering. Here, we report the discovery of spontaneous (no external energy input) hydrogen transfer from biological glucose reactions into SmNiO, an archetypal perovskite quantum material. The enzymatic oxidation of glucose is monitored down to ~5 × 10 M concentration via hydrogen transfer to the nickelate lattice.

Perovskite nickelates as electric-field sensors in salt water.

Designing materials to function in harsh environments, such as conductive aqueous media, is a problem of broad interest to a range of technologies, including energy, ocean monitoring and biological applications. The main challenge is to retain the stability and morphology of the material as it interacts dynamically with the surrounding environment. Materials that respond to mild stimuli through collective phase transitions and amplify signals could open up new avenues for sensing.

Strongly correlated perovskite fuel cells.

Fuel cells convert chemical energy directly into electrical energy with high efficiencies and environmental benefits, as compared with traditional heat engines. Yttria-stabilized zirconia is perhaps the material with the most potential as an electrolyte in solid oxide fuel cells (SOFCs), owing to its stability and near-unity ionic transference number. Although there exist materials with superior ionic conductivity, they are often limited by their ability to suppress electronic leakage when exposed to the reducing environment at the fuel interface.

Envelopment technique and topographic overlays in bite mark analysis.

Aims And Objectives: The aims and objectives of our study were to compare four sequential overlays generated using the envelopment technique and to evaluate inter- and intraoperator reliability of the overlays obtained by the envelopment technique.

Materials And Methods: Dental stone models were prepared from impressions made from healthy individuals; photographs were taken and computer-assisted overlays were generated. The models were then enveloped in a different-color dental stone.

Comparative efficacy of cedarwood oil and xylene in hematoxylin and eosin staining procedures: An experimental study.

Background: Xylene is used as a clearing agent in hematoxylin and eosin (H and E) staining of tissue sections in routine histopathology based diagnosis. However, the hazards associated with exposure to xylene are of concern. Numerous solutions mainly essential oils have been evaluated in the past as clearing agents, which can possibly be substituted for xylene during the routine tissue processing.

Essential thrombocythemia: Rare cause of chorea.

Essential thrombocythemia (ET) is a clonal myeloproliferative disorder (MPD), characterized predominantly by a markedly elevated platelet count without known cause. It is rare hematological disorder. In ET clinical picture is dominated by a predisposition to vascular occlusive events and hemorrhages.

Alterations in serum lipid profile patterns in oral cancer.

Background: Alterations in serum lipids have long been associated with cancer as lipids play an important role in maintenance of cell integrity.

Aims: To evaluate alterations in plasma lipid profile in oral cancer patients, to compare and correlate the serum lipid profile in different grades of carcinoma and to evaluate the correlation of serum lipid profile between the tobacco habituates and non-habituates.

Materials And Methods: Among 75 study subjects, 50 individuals were oral carcinoma patients and 25 individuals were healthy controls.

Simultaneous separation and preconcentration of trace elements in water samples by coprecipitation on manganese dioxide using D-glucose as reductant for KMnO(4).

A field oriented and economical method of coprecipitation of trace elements like Al, Au, Bi, Cd, Co, Cu, Fe, Mo, Ni, Pb, Pd, Ti, V, W, Zn and REE has been developed. A novel reductant D-glucose, reduces KMnO(4) in solution to form a precipitate of MnO(2.) Two liters of clear natural water sample is adjusted to pH 3.

Removal of ocular artifacts from EEG using adaptive thresholding of wavelet coefficients.

Electroencephalogram (EEG) gives researchers a non-invasive way to record cerebral activity. It is a valuable tool that helps clinicians to diagnose various neurological disorders and brain diseases. Blinking or moving the eyes produces large electrical potential around the eyes known as electrooculogram.
