Herein, we report the soft-templated preparation of mesoporous iron oxide using an asymmetric poly(styrene-b-acrylic acid-b-ethylene glycol) (PS-b-PAA-b-PEG) triblock copolymer. This polymer forms a micelle consisting PS core, PAA shell, and PEG corona in aqueous solutions, which can serve as soft template. The obtained at optimized calcination temperature 400 °C exhibited average pore diameter 39 nm, with large specific surface area volume 86.9 m2 g–1 0.218 cm3 g–1, respectively....

Cryopreservation without cryoprotectant remains a significant challenge for the re-establishment of cell culture after freeze–thaw. Thus, finding an alternative and simple cryopreservation method is necessary. Liquid marble (LM)-based digital microfluidics promising approach cryoprotectant-free cryopreservation. However, use this platform to efficiently preserve samples with low density well-controlled serum concentrations has not been investigated. We addressed issue by embedding...

2.02% conversion efficiency Dye-sensitized solar cell (DSSC) is achieved based on an additional insulating layer of Li doped ZnO nanoparticles (LZN) onto SnO2 nanocomposite photoanode. The morphology, incident photon to current (IPCE), AC impedance and photovoltaic performance were investigated nanocomposited, nanoflower nanoparticle photoanodes DSSCs. Suppression recombination rate in DSSC, has a high filling factor 68.9% with 80.6% IPCE. improved the interconnections between nanoflowers...

Li-doped ZnO (LZO) aggregated nanoparticles are used as an insulating layer in SnO2 nanocomposite (SNC) photoanodes to suppress the recombination process dye-sensitized solar cells (DSSCs). Various weight percentages of (SNPs) and nanoflowers (SNFs) were prepare SNC photoanodes. The photocurrent-voltage characteristics showed that incorporation LZO photoanode increased conversion efficiency DSSCs. This was due increase surface area, charge injection, collection, minimization rate...

The applications of Silicon gated field emitter arrays (Si-GFEAs) have always been limited by failures (arcs) which attributed to a number reasons: (a) tip runaway due ion space charge-initiated emission, (b) bombardment, (c) thermal runaway, and (d) surface breakdown [1]. resulting cathodic arcs can be measured experimentally [2], the damage observed. We studying arc initiation silicon tips [3] both with experiment simulation. Experimentally, we are measuring electrical signature under...

Summary form only. The reliability of Silicon Gated Field Emitter arrays (Si- GFEAs) [1] should be studied before practical realization. failure these may due to tip current runaway, possibly from ionization gas molecules [2] or could emitter gate surface breakdown along the dielectric, where a conducting leakage path is formed between and gate. Initial experiments were carried out using an arc detection circuit [3] for array sizes 25x25, 32x32, 50x50. A constant DC voltage 50V was applied...
