In vitro modelling offers the potential of recapitulating human degenerate tissue for physiological studies and pharmacological screening. Yet, few systems have been developed to date, primarily due to the lack of vascularisation in engineered tissue. Here, the development of an in vitro pump is addressed. This will b…
There have been numerous attempts to model fast reactor fuel behavior in the last 40 years. The US currently does not have a fully reliable tool to simulate the behavior of metal fuels in fast reactors. The experimental database necessary to validate the codes is also very limited. The DOE-sponsored Advanced Fuels Cam…
In this report I will address the topic of nanocomposite materials and their various future applications based on current research in the field. I describe several processes of how different nanocomposites are synthesized from their component parts and how these parts act with each other to produce the qualitative eff…
Water wetting on a hydrophobic surface at ambient conditions is disallowed by the nonpolar nature of the surface and high vapor pressure of water. However, the presence of sub-millimeter sized hydrophilic patches allows the waxy wings of desert beetles to become wettable by morning mist. Here, we show that a sprinkle…
800x600 A DETERMINATION OF DEGRADATION CAPABLITY OF RSG-GAS PIPING SECONDARY COOLING SYSTEM. A research of degradation capabilities of RSG-GAS secondary cooling piping system has been done in G.A. Siwabessy Multy Purpose Reactor Serpong. The research involved hardness test and thickness inspection of the pipe wall. Th…
This research aimed to investigate the effect of width plate variation to distortion caused by welding in AISI 1045 light steel alloy plate. This kinds of steel is formable by heat treatment and often for making mechanical component use. Sometimes repairing mechanical component was done by welding. The deformation tha…
A discarded motherboard based eco-friendly copper catalyst has been\nprogrammed to replace the industrially used tin based catalyst DBTDL. The\ncatalyst has been characterized by UV-Vis spectroscopy, FT-IR and TEM. Using\nthe catalyst reaction conditions is optimized and under the optimized\ncondition, both polyuretha…
Cet abrasif de granulometrie typique de 125 microns (100 a 200 microns) Il est principalement utilise pour le decapage du bois, fenetre, porte, Volets etc… Bardage, poutres et parquets.
Co-crystals are multi-component, single phase materials in which the co-crystal formers exist in an uncharged state. This interaction between components occurs without affecting the intra-molecular covalent bonding of the involved components or altering their chemical integrity. This class of materials has recently ga…
The formation of three-dimensional (3D) models for tissue engineering purpose provides a more conducive environment to enable complex biological interactions and processes between cells, biomaterials and bioactive molecules. Microparticles (MP) can be used as supporting matrix for 3D construct in cells and a carrier t…
A conceptual framework is developed and used to obtain a molecular descriptor for supervised learning of potential energy surfaces. Starting from the external potential, entering any electronic Hamiltonian, the representation is obtained through a Fourier transform, and use of atomic radial distribution functions as a…
The synthetic polymers reported in this thesis are able to bind the small molecule autoinducer-2 (AI-2) in the Quorum Sense (QS) pathways of the marine organism with high affinity, and some of the polymers are also able to sequester rapidly the same bacteria from suspension. Specifically, the Alizarin Red S (AR-S) ass…

Cet abrasif de granulometrie typique de 350 microns (200 a 500 microns) est utilise pour le decapage difficile de metaux, l'enlevement de la rouille.
The oral route for drug administration offers an efficient and convenient method for drug delivery. However, there is an assortment of drugs which exhibit narrow absorption windows in the upper small intestine and as a result demonstrate limited bioavailabilities. One approach in the improvement of bioavailability in…
This article evaluates the potential for colloidal, semiconducting nanocrystals for use as the photoabsorbing layer in spray-deposited photovoltaic cells. Future needs for renewable energy can be met through the implementation of photovoltaic cells, which are able to be mass produced at a low cost. After presenting an…
We introduce a fingerprint representation of molecules based on a Fourier series of atomic radial distribution functions. This fingerprint is unique (except for chirality), continuous, and differentiable with respect to atomic coordinates and nuclear charges. It is invariant with respect to translation, rotation, and…
The nanoscopic magneto-electronic phase separation in doped La1-xSrxCoO3 perovskites was studied with local probes. The phase separation is directly observed by M\"ossbauer spectroscopy in the studied doping range of 0.05 <= x <= 0.25 both at room-temperature as well as in the low temperature magnetic phase. Extended…
Clean water is one of the most challenging issues facing humanity today resulting in widespread research on new water purification and disinfection techniques emphasizing on optimized energy consumption. Nanotechnology has significantly contributed to the lowering the cost of eco-friendly water disinfecting processes.…
This chapter discusses dielectric properties of microwave ceramics, such as the dielectric constant, the temperature coefficient of resonant frequency, and the quality factor. It presents an overview of microwave dielectric materials. The chapter talks about crystal chemistry of perovskite and tungsten-bronze-type mic…
