Boron nitride nanotubes (BNNTs) exhibit a range of properties that are as compelling those carbon (CNTs); however, very low production volumes have prevented the science and technology BNNTs from evolving at even fraction pace CNTs. Here we report high-yield small-diameter pure hexagonal boron powder in an induction thermal plasma process. Few-walled, highly crystalline (∼5 nm) produced exclusively unprecedentedly high rate approaching 20 g/h, without need for metal catalysts. An...
A multifunctional architecture for biomedical applications has been developed by deliberately combining the useful functions of superparamagnetism, luminescence, and surface functionality into one material. Good control core−shell achieved employing a sol−gel synthesis. Superparamagnetic iron oxide nanoparticles are first coated with silica to isolate magnetic core from surrounding. Subsequently, dye molecules doped inside second shell improve photostability allow versatile functionalities....
Numerous studies have described the altered expression and causal role of microRNAs (miRNAs) in human cancer. However, to date, efforts modulate miRNA levels for therapeutic purposes been challenging implement. Here we find that nucleolin (NCL), a major nucleolar protein, posttranscriptionally regulates specific subset miRNAs, including miR-21, miR-221, miR-222, miR-103, are causally involved breast cancer initiation, progression, drug resistance. We also show NCL is commonly overexpressed...
Boron nitride nanotubes (BNNTs) exhibit a range of properties that hold great potential for many fields science and technology; however, they have inherently low chemical reactivity, making functionalization specific applications difficult. Here we propose covalent BNNTs via reduction chemistry could be highly promising viable strategy. Through density functional theory calculations the electron affinity their binding energies with various radicals, reveal reactivity can significantly...
Jumbo bacteriophages of the ϕKZ-like family assemble a lipid-based early phage infection (EPI) vesicle and proteinaceous nucleus-like structure during infection. These structures protect from nucleases may create selective pressure for immunity mechanisms targeting this specific family. Here, we identify "jumbo killer" (Juk), two-component immune system that terminates phages, suppressing expression genes preventing DNA replication nucleus assembly while saving cell. JukA (formerly YaaW)...
A novel method combining wet chemistry for synthesis of an Fe core, 532 nm laser irradiation nanoparticles and Au powder in liquid medium deposition shell, sequential magnetic extraction/acid washing purification has been developed to fabricate oxidation-resistant Fe@Au core-shell nanoparticles. The have extensively characterized at various stages during up several months after completion the by a suite electron microscopy techniques (HRTEM, HAADF STEM, EDX), X-ray diffraction (XRD), UV-vis...
225Ac is considered as one of the most promising radioisotopes for alpha-therapy because its emitted high-energy α-particles can efficiently damage tumor cells. However, it also represents a significant threat to healthy tissues owing extremely high radiotoxicity if targeted therapy fails. This calls pressing requirement monitoring biodistribution in vivo during treatment tumors. lack imageable photons or positrons from therapeutic doses makes this task currently quite challenging. We report...
We present the results of controlled synthesis core−shell nanostructures and influence silica coating on magnetic properties formed hybrid nanoparticles. The nanoarchitectures composed iron oxide cores amorphous shells have been synthesized through a sol−gel approach characterized by transmission electron microscopy, energy dispersive X-ray analysis, magnetometry. It is found that many nanoparticles contain single core. A good control shell thickness (10−100 nm) has achieved adjusting silane...
Single-walled carbon nanotubes (SWCNTs) have been used as fillers to produce electrically conductive composite papers. While papers made using other fillers, they either suffer from instability or low conductivity. Using simple papermaking techniques, we SWCNT–cellulose paper which possesses a conductivity of 3 × 10−2 S cm−1 and is comparable exceeds reports nanotube–cellulose by layer-by-layer assembly. These are multifunctional, having both improved electrical enhanced flame retardant...
Reduced single-walled carbon nanotubes (r-SWCNT) are shown to react readily at room temperature under inert atmosphere conditions with epoxide moieties, such as those in triglycidyl p-amino phenol (TGAP), produce a soft covalently bonded interface around the SWCNT. The is compatible SWCNT-free cross-linked cured matrix and acts toughener for composite. Incorporation of 0.2 wt % r-SWCNT enhances ultimate tensile strength, toughness fracture by 32, 118, 40%, respectively, without change...
While production of engineered carbon nanotubes (CNTs) has escalated in recent years, knowledge risk associated with exposure to these materials remains unclear. We report on the cytotoxicity four CNT variants human lung epithelial cells (A549) and murine macrophages (J774). Morphology, metal content, aggregation/agglomeration state, pore volume, surface area modifications were determined for pristine oxidized single-walled (SW) multi-walled (MW) CNTs. Cytotoxicity was evaluated by cellular...
Boron nitride, which possesses high thermal conductivity, is often incorporated into polymer matrixes for management. The enhancement in the conductivity depends on filler shape, size, effective dispersion matrix, and interfacial resistance between last two are most challenging issues. To address these challenges, this study different covalent functionalization approaches boron nitride nanotubes (BNNTs) with short polyethylene (PE) chains employed: one based Williamson reaction other nitrene...
An agent for actinide sequestration with fast uranium uptake kinetics and efficient in vivo removal using a nanoscale metal-organic framework (nano-MOF) is proposed. UiO-66 nanoparticles post-synthetically functionalized carboxyl groups, UiO-66-(COOH)4 -180, exhibit the fastest reported more than 65 % of uranyl fetal bovine serum (FBS) removed within 5 min. Moreover, bio-distribution studies show that material partially accumulates kidneys femurs where mainly deposits facilitating uranium....
Current processes to manufacture nanotubes at commercial scales are unfortunately imperfect and commonly generate undesirable byproducts. After manufacturing, purification is necessary a rate cost determining step in advancing the development of products based on nanotubes. Boron nitride (BNNTs) produced without metal catalysts from high-temperature known contain significant amount (e.g., 50 wt %) various boron derivatives. Herein we report simple yet efficient scalable process purify these...
Single-walled carbon nanotubes (SWCNTs) covalently modified with OH functional groups were assembled into buckypapers through solvent dispersion and vacuum filtration. These SWCNT-OH buckypaper sheets subsequently crosslinked by wetting bifunctional linkers followed hot compression causing reaction between the of reagent on side-walls SWCNTs to create three-dimensional (3D) cross-linked buckypapers. Cross-linking also was performed using encapsulated a functionalized polymer wrapping in...
