The paper studies the compressibility of directly compressible tableting materials with dry binders, spray-dried lactose and microcrystalline cellulose, and glyceryl dibehenate at various concentrations. Compressibility was evaluated by means of the energy profile of compression and tensile strength of tablets. Release rate of the active ingredient, salicylic acid, from the tablets was also exa...
Introduction: The results presented here are part of an investigation into the evolution of hydrothermal events associated with the Chicxulub impactites in Yu-catan, Mexico. The study focuses on alteration products in core samples recovered from the Yaxcopoil-1 drill hole, which is located some 60 kilometers from the center of the impact structure. This research contributes to the growing knowl...
Plant feedstocks are at the leading front of the biofuel industry based on the potential to promote economical, social and environmental development worldwide through sustainable scenarios related to energy production. Penicillium echinulatum is a promising strain for the bioethanol industry based on its capacity to produce large amounts of cellulases at low cost. The secretome profile of P. ec...
Microcrystalline sodium tungsten bronze nanowire bundles were obtained via a facile hydrothermal synthesis, and were applied in water purification as visible-light-driven photocatalysts for the first time.
The hardness, heat conductivity and low friction coefficient of microcrystalline diamond make it a suitable candidate for tribological applications. However, its roughness and high deposition temperature pose significant obstacles to these applications. We have successfully grown nanocrystalline diamond on steel at 400 °C by hot-filament chemical vapor deposition by employing a CrN interfacial ...
A novel greener method to impregnate silver nanoparticles (AgNPs) into microcrystalline cellulose (MCC) by curry leaf (Murraya koenigii) extract is presented. The active reduction of silver ions by curry leaf extract was explored for the in situ impregnation AgNPs into MCC. Transmission electron microscopy (TEM) analysis of MCC coated with AgNPs showed the formation of silver particle sizes in ...
This work demonstrates the preparation of spherical nanocellulose from microcrystalline cellulose by controlled hydrolysis using anaerobic microbial consortium. The nanocellulose formed during the degradation of microcrystalline cellulose was separated by ultra filtration membrane and purified by differential centrifugation. The purified nanocellulose was characterized by nanoparticle size anal...
Work function measurements on cross sectioned microcrystalline pin silicon solar cells deposited by Hot−Wire CVD are presented. The experiment is realized by combining a modified Kelvin probe experiment and a scanning force microscope. The measured surface potential revealed that the built−in electric drift field is weak in the middle of the compensated intrinsic layer. A graded donor distribut...
