Synthesis of Titanium Nanoparticles with Controlled Size Variation by Physical Vapor Deposition

Alzubi F.G., Kuwait Institute for Scientific Research, KW

In this work, we were able to control the diameter of the formed Ti nanoparticles by varying the deposited film thicknesses to different values 2, 4, 6, 8, and 18 nm. Size, distribution, topography, and [...]

Physio-structural and immunological characterization of a PLGA 85/15 encapsulated Chlamydia recombinant MOMP nanovaccine candidate

Sahu R., Dixit S., Singh S.R., Dennis V.A., Alabama State University, US

The quest for vaccine development against Chlamydia trachomatis (CT), the leading cause of bacterial sexually transmitted diseases worldwide, has escalated to reduce its occurrence and global economic burden. Recently, nanovaccines have emerged as attractive candidates [...]

Sustained Release of Functional Interleukin-10 Encapsulated within Poly (lactic acid)-b-Poly (ethylene glycol) Nanoparticles Down-regulates Cytokines in Mouse Macrophages Exposed to Chlamydia trachomatis

Duncan S., Dixit S., Sahu R., Nyairo E., Singh S.R., Dennis V.A., Alabama State University, US

Inflammation which is induced by the presence of cytokines and chemokines is an integral part of Chlamydial infection. Chlamydia trachomatis (CT), the bacterial pathogen responsible for this sexually transmitted infection worldwide, causes severe inflammation including, [...]

Development and Characterization of Commercial Boron Nitride Nanotube Product Forms

Jakubinek M.B., Martinez-Rubi Y., Kim K.S., Jakubek Z.J., Homenick C.M., Zou S., Klug D., Ashrafi B., Guan J., Walker S., Daroszewska M., Kingston C.T., Simard B., National Research Council Canada, CA

Boron nitride nanotubes (BNNTs) are structurally analogous to carbon nanotubes (CNTs) and possess equally impressive mechanical properties along with a different set of multifunctional properties including higher thermal stability than CNTs, wide band gap, electrical [...]

Pore Size and its Effect on Molybdenum Retention in Mesoporous Alumina

Hepburn R., Tsubota S., Fujimi Corporation, US

Mesoporous alumina is used as the adsorbent for retaining Molybdenum-99 in the Molybdenum/Technetium generators used for medical imaging. Highly enriched uranium (HEU) has been historically used to create radioactive molybdenum for this purpose. However, in [...]

Bai J., Shi Z., Wu Z., Jia S., Xi'an Jiaotong University, CN

Al nanoparticles have important applications in various fields, e.g., solid rocket propellant, explosives [1], electronics [2], detection of biomolecules [3], and enhancement of the properties of various nanocomposites [4-6], etc. Among various synthesis methods of [...]

Modeling and simulation of nanoparticle production in an aerosol flame reactor

Buddhiraju V.S., Nadimpalli N.K.V., Runkana V., TCS Research, Tata Research Development and Design Centre, A division of Tata Consultancy Services, IN

Aerosol flame synthesis is one of the commonly used methods for producing nanoparticles on a large scale. Large volumes of ultra-fine materials such as titania, silica, carbon black and zinc oxide etc. are produced in [...]

Transition Metal Dichalcogenides as Cell Culture Platforms

Palumbo A., Tourlomousis F., Chang R., Yang E.H., Stevens Institute of Technology, US

Transition metal dichalcogenides (TMDs), such as WS2 and MoS2, have been widely explored for their utilization as two-dimensional (2D) semiconducting nanomaterials with unique electronic, mechanical, and catalytic properties. A multitude of research has been pursued [...]
