Nanoporous Silica Embedded in Nanoporous Platinum: A Versatile Composite Coating for Implant‐Associated Drug Delivery From Neuronal Electrodes

Advanced Materials Technologies, EarlyView.
Nanoporous silica nanoparticles incorporated in nanoporous platinum offer the possibility for implant‐associated drug delivery from neuronal electrodes. ABSTRACT Sensorineural hearing loss, resulting from damage to the hair cells of the inner ear, profoundly impairs quality of life.

Burner development for efficient combustion of biogas

Vestnik IGEU, 2020
Now in metallurgical production energy resources demand is almost completely satisfied by gaseous fuel. Biogas obtained during organic waste processing is considered as an alternative and cheaper type of fuel. The experience of biogas application has shown that in most modern burners decrease of efficiency and limitation of the range of load regulation

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

Advanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

A Fundamental Investigation on the High Intensity Combustion : 1st Report, On the Local Combustion Efficiency in an Upright Combustion Chamber

Transactions of the Japan Society of Mechanical Engineers, 1967
The local combustion efficiency and the local heat release rate in an upright cylindrical combustion chamber having a diameter of 100 mm and a length of about 1000 mm, were experimentally determined from the contents of combustion products. The burnt gases sampled from ten positions in the combustion chamber were analyzed with gaschromatograph.
