A micro- and nanoscale complex structure made of a high refractive index polymer (n = 2.08) was formed on the ITO electrode layer of an edge-emitting type GaN blue light-emitting diode (LED), in order to improve the photon extraction efficiency by suppressing total internal reflection of photons. The nanoimprint lithography process was used to form the micro- and nanoscale complex structures, u...

A drug-delivery microdevice integrating pH-responsive nano-hydrogel particles functioning as intelligent nano valves is described. The polymeric microdevices are monolithic without requiring peripheral control hardware or additional components for controlling drug-release rates. pH-responsive nanoparticles were synthesized and embedded into a composite membrane. The resulting pH-responsive comp...

There have been many studies on superwetting surfaces owing to the variety of their potential applications. There are some drawbacks to developing these films for biomedical applications, such as the fragility of the microscopic roughness feature that is vital to ensure superwettability. But, there are still only a few studies that have shown an enhanced durability of nanoscale superwetting fil...

Hollow C70 nano/submicro-crystals with a fcc lattice structure were treated under various high pressure and high temperature conditions. The energy band structure was visibly changed by the high pressure and high temperature treatment, and the luminescence of the treated C70 nano/submicro-crystals were tuned from the visible to the near infrared range. In-situ high pressure experiments at room ...

OBJECTIVES The present study reports on the preparation and testing of a desoxycholate amphotericin B (D-AMB) sustained delivery system based on poly(lactic-co-glycolic acid) (PLGA) and dimercaptosuccinic acid (DMSA) polymeric blends (Nano-D-AMB) aimed at reducing the number of AMB administrations required to treat mycosis. METHODS BALB/c mice were infected with the yeast Paracoccidioides bra...

Expression of concern for ‘Solar-driven photodegradation 17-β-estradiol and ciprofloxacin from waste water CO 2 conversion using sustainable coal-char/polymeric-g-C 3 N 4 /RGO metal-free nano-hybrids’ by Amit Kumar et al. , New J. Chem. 2017, 41 10208–10224, https://doi.org/10.1039/C7NJ01580A.

Benefits of employing carbon nanotubes (CNTs) as a component of large-scale composite structures include mechanical (strength, toughness, etc.) as well as multifunctional property tailoring. In this experimental work, aligned-CNT forests and polymeric composites of aligned-CNTs are tested for both DC and AC electrical properties. Understanding the aligned-CNT forest and nanocomposite behavior i...

maybe viscosity in drilling fluid is the most important parameter because cutting removal from well are task of viscose fluid. if viscosity of fluid is less than particular value, cutting will settle down in well and drilling operation will be stopped. in this study, synthesis of alumina/polyacrylamide nanocomposite through solution polymerization method was performed. rheological behavior of m...
