Ceramics have excellent properties such as hardness and thermal chemical stability. Therefore, researchers studied the use of 3D printing to produce complex shapes in tools structural applications. The debinding sintering processes for ceramic composite materials manufactured using digital light processing (DLP) technology were studied. slurry used DLP requires sintering, it contains ceramics b...

A configuration of three-dimensional Ni-Si nanocable array anodes is proposed to overcome the severe volume change problem of Si during the charging-discharging process. In the fabrication process, a simple and low cost electrodeposition is employed to deposit Si instead of the common expansive vapor phase deposition methods. The optimum composite nanocable array electrode achieves a high speci...

We report the application of our dc SQUID (superconducting quantum interference device) spectrometer [C. Connor, J. Chang, and A. Pines, Rev. Sci. Instrum. 61, 1059( 1990)] to nuclear quadrupole resonance (NQR) studies of aluminum-27, and boron-II in crystalline and glassy solids. Our results give eqQ /h = 2.38 MHz and 1] = 0.0 for a-A120 3 at 4.2 K. For the natural mineral petalite (LiAISi4 01...

One of the present challenges in optical coherence tomography (OCT) is the visualization of deeper structural morphology in biological tissues. Owing to a reduced scattering, a larger imaging depth can be achieved by using longer wavelengths. In this work, we analyze the OCT imaging depth at wavelengths around 1300 nm and 1600 nm by comparing the scattering coefficient and OCT imaging depth for...

Two alloys based on nickel and designed to be reinforced by MC carbides thanks the presence of Hf Ta were produced casting. They subjected 50 h-long isothermal exposure at 1250 °C in synthetic air with thermogravimetric monitoring oxidation progress. In as-cast state, they contain both significant quantities (Hf,Ta)C carbides. Their verified melting start temperatures, close 1300 °C, allowed pe...

Plasmodium falciparum malaria is one of the leading infectious causes of childhood mortality in Africa. EP-1300 is a polyepitope plasmid DNA vaccine expressing 38 cytotoxic T cell epitopes and 16 helper T cell epitopes derived from P. falciparum antigens expressed predominantly in the liver phase of the parasite's life cycle. We performed a phase 1 randomized, placebo-controlled, dose escalatio...

We present a comparative study of two-photon excited fluorescence (TPEF) and second harmonic generation (SHG) imaging in turbid media at 800- and 1300-nm excitation. The depth-dependent decay of TPEF and SHG signals in turbid tissue phantoms is used to estimate the impact of light scattering on excitation intensity at each wavelength. A 50 to 80% increase in scattering length is observed using ...

Abstract Adjusting the grain growth orientation may be a feasible way to improve oxidation resistance. In this work, textured Ti 3 (SiAl)C 2 ceramic was successfully fabricated via spark plasma sintering technique. The crystal and microstructure were investigated by XRD combined with EBSD. behavior of at 1000–1300 °C for 10 h. results showed that significantly anisotropic surface parallel compr...
