Thermally stable superhydrophobic fabrics with multifunctionality were fabricated through the combination of sol–gel chemistry and electrospinning. MTES sols electrospun into fibers, in which fiber morphology was controlled by gelation time. The resulting are not only very heat-resistant but perform high filtration efficiency, enabling emerging applications for smart materials devices. Detailed facts importance to specialist readers published as "Supporting Information". Such documents...
Many chemical and biological processes are dependent on molecular gradients. We describe a new microfluidic approach that can be used to produce spatiotemporal gradients across two-dimensional surfaces three-dimensional gels under flow-free conditions. Free diffusion between dynamically replenished flow channels acting as sink source is utilized give rise stable steady-state gradient profiles. The profile dictated by the engineered design of device's gradient-generating region. Different...
Li[Ni1/3Co1/3Mn1/3]O2 synthesized via the modified carbonate process showed a homogeneous particle distribution with 10-μm secondary particles. Higher discharge capacity was retained even at 10 C (2800 mA g-1). This superior high rate capability would be mainly due to well-controlled synthesis process, thus morphology and its effects on electrochemical properties are significantly reproducible.
We demonstrate the fabrication of solvent-resistant, mechanically robust, superhydrophobic nanofibrous mats by electrospinning poly(vinylidene fluoride) (PVDF) in presence inorganic silane materials. The solvent resistance and mechanical strength were dramatically increased through crystallization as-spun PVDF fibers or incorporation a tetraethyl orthosilicate (TEOS) sol into matrix. electrospun yielded water contact angle 156° that did not vary with TEOS content. robustness significantly...
Abstract Drugs are currently being developed to attenuate oxidative stress as a treatment for brain injuries. C-phycocyanin (C-Pc) is an antioxidant protein of green microalgae known exert neuroprotective effects against injury. Astrocytes, which compose many portions the brain, various functions overcome stress; however, little about how C-Pc mediates antioxidative astrocytes. In this study, we revealed that intranasal administration middle cerebral artery occlusion (MCAO) rats ensures...
Many investigations of wound dressings equipped with drug delivery systems have recently been conducted. Chitosan is widely used not only as a material for dressing by the efficacy its own, but also nanoparticle delivery. In this study, an electrospun polycaprolactone nanofiber composite chitosan nanoparticles (ChiNP–PCLNF) was fabricated and then evaluated release biocompatibility to skin fibroblasts. ChiNP–PCLNF complexes showed no cytotoxicity adsorbed van der Waals force were released...
Skin regeneration is a complex process involving massive proliferation and alignment of cells, where there are obstacles to completion regeneration, the main one being excessive generation reactive oxygen species (ROS) from inflammation or infection. Spirulina , blue-green algae that has antioxidant anti-inflammatory activities, been used relieve such ROS stress. In this study, extract loaded PCL ( -PCL) nanofiber was evaluated as cutaneous wound dressing in view antioxidative mechanism....
Abstract Harvesting of microalgae is a cost-consuming step for biodiesel production. Cellulose has recently been studied as biocompatible and inexpensive flocculant harvesting via surface modifications such cation-modifications. In this study, we demonstrated that cellulose nanofibrils (CNF) played role microalgal its network geometry without cation modification. Sulfur acid-treated tunicate CNF flocculated microalgae, but nanocrystals (CNC) did not. addition, desulfurization not...
Cellular membrane distortion invokes variations in cellular physiology. However, lack of an appropriate system to control the stress and facilitate molecular analyses has hampered progress relevant studies. In this study, a microfluidic that finely manipulates Chlamydomonas reinhardtii (C. reinhardtii) was developed. The device facilitated first-time demonstration directs deflagellation, cell cycle lipid metabolism. C. showed prolonged G1 phase with extended total time upregulated Mat3...
Nanomaterials are attractive for use in biological systems due to their ability control the microenvironment of cells. Additionally, nanofibers can mimic fibrous characteristics natural tissues. This study was conducted assess astrocyte activity and infiltration behavior on Spirulina extract‐embedded polycaprolactone (SP‐PCL) nanofiber. Astrocytes moved along with nanofiber, developed an elongated stellate shape, which is similar those neural tissue. In addition, expression GFAP, a biomarker...
