Template-driven strategy has been widely used to synthesize inorganic nano/micro materials. Here, we a bottom-up controlled synthesis route develop powerful solution-based method of fabricating three-dimensional (3D), hierarchical, porous-Co3O4 superstructures that exhibit the morphology flower-like microspheres (hereafter, RT-Co3O4). The gram-scale RT-Co3O4 was facilely prepared using one-pot with bacterial templating at room temperature. Large-surface-area also noticeable pseudocapacitive...
Human amniotic membrane isolated from the placenta contained basement components such as type IV collagen, laminin, and 6 4 integrins, all of which remained detectable while preserved in glycerin for one week. One month after n-heptanol removal total corneal epithelium limbal lamellar keratectomy, rabbit eyes carried features deficiency, including conjunctival epithelial ingrowth, vascularization chronic inflammation. Ten control then received a 13 experimental an additional transplantation....
Change in the expression of body fluid proteins is caused by many diseases or environmental disturbances. The changes tear are also associated with various pathological eye conditions. Especially, chronic blepharitis one most common conditions seen ophthalmologist's office. However, there no specific clinical diagnostic tests for blepharitis, and it difficult to treat effectively. Therefore, aim this study was screen prognostic marker investigate pathogenesis disease using proteomics...
Germanium (Ge) nanoparticle–multiwalled carbon nanotube (MWCNT) anodes are fabricated through the anchoring of Ge on surface electrophoretically pre-deposited MWCNT networks via a thermal evaporation process. This Ge–MWCNT nanocomposite displays large reversible capacity over 800 mA h g−1 at 1 C even after 200 cycles.
We prepared Na<sub>2</sub>FeP<sub>2</sub>O<sub>7</sub> NPs embedded in carbon and fabricated a free-standing electrode using nanoparticles porous cloth for flexible high-rate Na-ion batteries with superior cycling stability.
Clinical and Immunological Responses in Ocular DemodecosisThe purpose of this study was to investigate clinical immunological responses Demodex on the ocular surface.Thirteen eyes 10 patients with blepharitis chronic surface disorders were included treated by lid scrubbing tea tree oil for eradication Demodex.We evaluated manifestations counts, analyzed IL-1β, IL-5, IL-7, IL-12, IL-13, IL-17, granulocyte colony-stimulating factor, macrophage inflammatory protein-1β tear samples before after...
Lithium‐oxygen batteries represent a significant scientific challenge for high‐rate and long‐term cycling using oxygen electrodes that contain efficient electrocatalysts. The mixed transition metal oxide catalysts provide the most catalytic activity partial heterogeneous surface cations with vacancies as active phase. They include multiple oxidation states vacancies. Here, combination of transmission electron microscopy, differential electrochemical mass spectrometry, X‐ray photoelectron...
Lithium–oxygen batteries have been considerably researched due to their potential for high energy density compared some rechargeable batteries. However, it is known that the stability of a carbon-based oxygen electrode insufficient owing promotion carbonate formation, which results in capacity fading and large overpotential lithium–oxygen To improve chemical organic-based electrolytes, alternative electrocatalyst support materials are required. The Ti–O crystal system appears provide good...
Abstract Silicon has emerged as the most promising high-capacity material for lithium-ion batteries. Waste glass can be a potential low cost and environmentally benign silica resource enabling production of nanosized silicon at industry level. Windshields are generally made laminated comprising two separate bonded together with layer polyvinyl butyral sandwiched between them. Herein, silicon/carbon nanocomposites fabricated from windshields first time via magnesiothermic reduction facile...
