Similar to biological muscles, the actuator materials can function as artificial muscles by directly converting an external stimulus in form of electrical or chemical energy into a mechanical response through reversible changes material dimensions. As new type high surface-area materials, nanoporous metals represent novel class smart electrodes that undergo dimensional when applying electronic ...

A novel hybrid nanoporous material (LNH-1) bearing a tris(propyliminomethyl)-phloroglucinol fluorescent moiety in the framework has been designed and administration of an LNH-1 based drug delivery system containing doxorubicin to cancer cells showed inhibition of proliferation, suggesting its future potential theranostics application in cancer.

Melanized wild-type and melanin-deficient (Mel-) strains of Wangiella dermatitidis (Kano) McGinnis were tested for in vitro susceptibility to amphotericin B, flucytosine, amorolfine, ketoconazole, fluconazole, terbinafine, and itraconazole by using an agar dilution technique. Although the MICs of itraconzole obtained with seven of the eight Mel- strains were lower than those obtained with the m...

Here, we prepared LiMn0.8Fe0.2PO4 microspheres with an open three-dimensional nanoporous structure by a facile ion-exchange solvothermal method. The micro/nano-structured material exhibits an ultralong cycle life, and retains a reversible capacity of 105 mA h g(-1) after 1000 cycles at 5 C, corresponding to the capacity retention of 94.0% and only 0.0068 mA h g(-1) loss per cycle.

Nanostructured materials with feature sizes in tens of nanometers have enhanced the performance of several technologies, including fuel cells, biosensors, biomedical device coatings, and drug delivery tools. Nanoporous gold (np-Au), produced by a nano-scale self-assembly process, is a relatively new material that exhibits large effective surface area, high electrical conductivity, and catalytic...

this study aimed to investigate the potency of silymarin (smn) and melatonin (mel) on restoring the pancreatic  cells in streptozotocin (stz)-induced diabetic rats. male wistar rats were divided into five groups, including: control (c), untreated diabetic (d), smn-treated diabetic (50 mg/kg, orally), mel-treated diabetic (10 mg/kg, i.p.), and smn plus mel-treated diabetic rats. diabetes was in...

background renal ischemia reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered principal components involved in the pathophysiological tissue alterations observed during renal ir. objective in this study, we compared the effects of melatonin (mel) and erythropoietin (epo), which are known antioxidant and anti-inflammatory agents, in i...

Nanoporous gold is a promising material for multi-functional bio-interfaces with its well-characterized surface chemistry, compatibility with conventional micropatterning techniques, electrical conductivity, and high effective surface-area for molecular release. This paper demonstrates its biocompatibility and capability for drug release to modulate cellular response.

In this paper, the compensation of mismatch between clean training hidden Markov models (HMMs) and noisy test speech is addressed. The purpose is to approach the performance of Aurora2 multi-condition training but use only clean training material. The idea is to integrate three methods including (1) mean subtraction, variance normalization and ARMA filtering (MVA) post-processing for Mel-scaled...

A multiscale simulator for alumina film growth inside a nanoporous material during an atomic layer deposition process is developed. The model combines a continuum description at the macroscopic level of precursor gas transport inside a nanopore during exposure to each of the two precursor species (trimethyaluminum and water) with a lattice Monte Carlo simulation of the film growth on the micros...
