Pd-decorated amorphous Ni–B/C catalysts were successfully synthesized which exhibited enhanced oxygen reduction reaction activities in alkaline media.
AISI 321 austenitic stainless steel was treated using rf plasma carbonitriding with the intention of use low-cost orthopedic implant material in biomedical applications. The treatment process was carried at low working gas pressure of 0.075 mbar in nitrogen-acetylene gaseous mixture to form a superficial carbonitrided…
In this paper, a novel in situ ceramic composite consisting of Al2O3-SiC-C has successfully been prepared from waste fly ash material obtained from thermal power plant. The EDAX and X-ray studies have confirmed nearly complete conversion of SiO2 to SiC by thermal reduction in a plasma reactor. Particle size ranging be…
We investigate the reactivity to H2 of a chemisorbed CO2 species at electron traps on oxide surfaces, taking the single electron F(+) oxygen vacancy of the MgO(100) terrace as a model system. We find that multiple hydrogen addition steps form three interacting catalytic cycles, leading to the evolution of formaldehyde…
Shot peening is a surface impact treatment widely used in the automotive and aerospace industries to improve the performance of metal parts. In this study, microstructure evolution and mechanical properties of 2196 Al-Li alloy were investigated after shot peening. The surface state was studied by scanning electron mic…
The most significant finding of this study is that a hybrid liposomal cerasome with high stability and good biocompatibility was successfully developed for oral insulin delivery by incorporating poly (vinyl pyrrolidone) (PVP) into the cerasome followed by coating with chitosan (CS).
We propose a novel combined five‐degrees‐of‐freedom (5‐DOFs) hybrid magnetic bearing (HMB) with only one permanent magnet ring (PMR) used for turboexpanders. It has two radial magnetic bearing (RMB) units; each has four poles and one thrust magnetic bearing (TMB) to control 5‐DOFs. Based on one PMR, the bias flux of t…
Pyrene appended naphthalene derivative, NEDAP can selectively detect histidine via inter-molecular H-bond assisted molecular ring formation that imparts rigidity to the molecular assembly to inhibit the TICT (Twisted Intra-molecular Charge Transfer) process leading to fluorescence enhancement. 1H NMR titration, mass s…
Early diagnosis and prognosis monitoring are very important for the survival of patients with bladder cancer. To identify candidate biomarkers of bladder cancer, we used a combination of techniques including 2-DE, co-IP, western blot, LC-MS/MS, and immunohistochemistry. Hsp74 was identified with high expression in bla…
A reversible ionic supramolecular assembly is described which can be disrupted and reformed by application of either a heating–cooling cycle or a mild redox reaction.
Electroless deposition of a NiWP barrier layer on a SiO 2 substrate was investigated for all-wet Cu interconnect fabrication. In this study, the entire fabrication process including substrate activation, barrier layer electroless deposition, and direct Cu electrodeposition was modified. The SiO 2 substrate was activat…
Conversion of the cyclohexane oxidation reaction with TBHP catalyzed by VTiX in different solvents.
Nanosized Pt‐Sn/VC and Pt‐Co/VC electrocatalysts were prepared by a one‐step radiation‐induced reduction (30 kGy) process using distilled water as the solvent and Vulcan XC72 as the supporting material. While the Pt‐Co/VC electrodes were compared with Pt/VC (40 wt%, HiSpec 4000), in terms of their electrocatalytic act…
Intrinsically disordered regions (IDRs) in proteins are still not well understood, but are increasingly recognised as important in key biological functions, as well as in diseases. IDRs often confound experimental structure determination-however, they are present in many of the available 3D structures, where they exhi…
A carbon-based solid acid with high acid density was successfully prepared using camphor tree branches as raw materials through a novel method including dilute sulfuric acid activation, carbonization in refluxing solvent and sulfonation. Physical characterization was detected to show that the carbon-based acid is amor…
Gallium and aluminum codoped zinc oxide (GAZO) films were deposited at different temperatures by in-line sputtering. Aluminum is thermally unstable compared to other elements in GAZO films. The grains of GAZO films increase with deposition temperature. Coalescence between grains was observed for GAZO films deposited a…
The fusion reaction occurring in DD plasma is followed by emission of 2.45 MeV neutrons, which carry out information about fusion reaction rate and plasma parameters and properties as well. Neutron activation of beryllium has been chosen for detection of DD fusion neutrons. The cross-section for reaction 9Be(n, α)6He…
Surface functionalization of graphene oxide (GO) by choline bicarbonate, choline hydroxide, choline formate and choline caproate resulted formation of partially reduced GO.
In past few years, a lot of attention has been given for the development and application of aluminum-silicon-magnesium alloys due to their high strength to weight ratio, low density, and good resistance to fatigue crack growth. These alloys are attractive materials for application in advanced aerospace structures at l…
In this paper, we investigate different industrial applicable cleaning sequences on test wafers and PERC solar cells in comparison to a laboratory type RCA clean. The cleaning sequences pSC1, HF/HCl, HF/O3 and HF/O3 show lifetimes between 1 ms and 2 ms which is comparable to a laboratory type RCA clean corresponding t…
