Biomass conversion using reusable solid acid catalysts are highly desirable to comply with
the principles of green chemistry. Here, we report a sulfonic acid-functionalized hafnium …

Here, we report extraordinary field emission properties from one pot synthesized aligned
carbon nanotubes endowed with related Fe nanoparticles (NPs). The CNT configuration is …

The direct engagement of hafnium (Hf) in biological processes or its critical function in living
things is not well understood as of now. Unlike key elements like oxygen, carbon, hydrogen …

This work presents for the first time the possibility of reducing and tuning the work function of
field emission cathodes coated with metal oxides by changing the chemical composition of …

In recent years, hafnium oxide (HfO2) has gained increasing interest because of its high
dielectric constant, excellent thermal stability, and high band gap. Although HfO2 bulk and …

Hafnia (HfO2) hollow nanofibers (HNs) were synthesized by atomic layer deposition (ALD)
using electrospun nylon 6, 6 nanofibers as templates. HfO2 layers were deposited on …

The paper presents a study of a large-area field emitter based on a composite of vertically
aligned carbon nanotubes covered with a continuous and conformal layer of nickel oxide by …

Room-temperature atomic layer deposition (ALD) of HfO 2 was examined using tetrakis
(ethylmethylamino) hafnium (TEMAH) and remote plasma-excited water and oxygen. A …

In this paper, we tried to increase the current density of carbon nanotubes (CNTs) by
depositing double layer of CNTs instead of single layer. Both the layers of CNTs are …

Lanthanum boride (LaB x) thin films with various thicknesses were deposited on ZnO
nanowire arrays by electron beam evaporation. Field emission characteristics of ZnO …
