Crystalline supra sub-atomic frameworks containing drug particles, for instance sedate solvates, co-precious stones and consideration mixes, are getting a charge out of expanding consideration as they speak to new multi-segment shapes whose pharmaceutically applicable properties (for example fluid solvency, strength,…

Proper flow field design is an active research topic in the pursuit of improving performance for Polymer Electrolyte Membrane Fuel Cells (PEMFC). Important concerns remain as PEMFCs come to mass market including increasing power density, and decreasing system cost. Increasing the power density of fuel cells reduces th…
Scanning Probe Microscopy (SPM) is arguably the only tool that is available for direct nanoscale electrical and electrochemical characterization since electrical measurement through a highly localized area necessitates a nanoscale electrode. However, conventional SPM systems are functional only up to ~250°C under atmo…
The most common mitral valve (MV) disease is the MV regurgitation, in which the anterior leaflet and the posterior leaflet cannot coapt well and hence result in the leaking of blood from the left ventricle to the left atrium during the systolic phase. The treatment options include MV replacement and repair. In order t…
El presente documento de tesis, titulado Contactos en celulas de heterouni on de silicio , contiene el trabajo realizado para optar al grado de Doctor en Ciencias Fisicas. A continuacion se describen brevemente los seis capitulos y dos apendices en los que se divide dicho documento. En el capitulo 1 se describen las c…
Nitrogen-doped silicon carbide (SiC) (Silicon carbonitride or SiCN) thin films which has been generally used as a etch stopping layer. Recently It becomes more and more attractive as capping dielectric layers and diffusion barriers due to their performance is similar to silicon nitride (SiN) but having lower dielectri…
Indonesia telah berhasil memproduksi kendaraan tempur yang diakui oleh dunia internasional. Kendaraan yang diberi nama Anoa dan Komodo ini dikategorikan sebagai Battering Ram atau Kendaraan Pendobrak. Jenis ini digunakan untuk pertempuran khusus dan aktivitas anti teror. Kendaraan pendobrak ini mampu menabrak beton se…
New functions of polymer film can be developed by using template. We synthesized polypyrrole (PPy) as a conducting polymer in liquid crystal electrolyte solution. The liquid crystal electrolyte solution for the electrochemical polymerization contains monomer, electrolyte, and matrix liquid crystal. The electrochemical…
The oxygen reduction reaction (ORR) is an important energy conversion reaction, especially for fuel cells1 and metal–air batteries.2 Pt-based materials are widely recognized as superior ORR electrocatalysts , hindering this technology's commercialization because of their expensive and scarce nature;3 in addition, thes…
The SoLute Carrier (SLC) superfamily of membrane transport proteins comprises over 300 genes organized into 52 families. One of the SLC groups is the SLC4 family, the members of which mainly transport HCO 3 − , or a species related to HCO 3 − (e.g., CO 3 = ), together with another “coupled” ion across the plasma membr…
Solid oxide fuel cells (SOFCs) are widely thought to be among the most promising energy conversion devices due to their low environmental impact, high efficiency and fuel flexibility. BaFeO3-δ (BFO) stands out as one of the most electrochemically active iron-based SOFC cathodes. This work systematically investigates t…
The heteroatom (N, S, Cl, B, P, Fe, Co, Mn or Ni)-doped carbon materials, such as carbon nanotubes (CNTs)1, graphene2, graphitic arrays3, and amorphous carbon4, have drawn great attention due to their excellent electrocatalytic performance for ORR. However, among all these non-precious carbon-based catalysts, very few…
The Ti/SnO2-Sb2O5 anode is a promising material for the anodic oxidation of organic compounds for the application of wastewater treatment. The material consists of a thin film of Sb-doped SnO2 on the titanium substrate. The influence of Sb doping on the conductivity of SnO2 thin films has been well documented, but its…
Room-temperature ionic liquids (RTILs), i.e. organic molten salts with melting points below 100 ◦C, have been intensively developed for electrolytic media in various electrochemical systems due to the fact that RTILs have unique physicochemical properties such as favorable solubility of organic and inorganic compounds…
Current photoelectrochemical devices for water electrolysis suffer from low stability and efficiency. Aims to address both those needs have been realized using a system that uses two sequential solar light absorbers (semiconductors) — in conjunction with oxygen evolution reaction (OER) and hydrogen evolution reaction…
Room-temperature ionic liquids (RTILs) have been regarded as potential electrolytic media for electropolymerization processes.1 Many kinds of RTILs have been investigated for the electropolymerizations; however, RTILs based on tetracyanoborate (B(CN)4 -, TCB) anion have been rarely employed. On the other hand, we have…
Ti and Ti alloys are well known for their excellent chemical stability and biocompatibility. Ti metal shows high corrosion resistance due to the presence of protective native oxide film. Although TiO2 layer is stable and protective in action, it can be dissolved in HF [1-3]. Anodic dissolution of Ti in acidic fluoride…
Hydrogen has been considered as a potential alternative fuel for future energy supplies and can be produced through high temperature steam electrolysis. The technology can be realized through reversible operation of solid oxide fuel cells (SOFCs), involving reduction of water at the cathode to form hydrogen and reject…
Several proposed beyond-CMOS devices based on two-dimensional (2D) heterostructures require the deposition of thin dielectrics between 2D semiconductor layers as an interlayer, or on the 2D semiconductor as a gate. However the direct deposition of dielectrics on 2D materials is challenging due to their inert surface c…
