Energy distribution function based universal adsorption isotherm model for all types of isotherm [PDF]

, 2018
Based upon the adsorbate-adsorbent interactions due to pore size distribution and surface heterogeneity, as characterized by the adsorption isotherms, the adsorption phenomenon has many industrial and environmental applications.

Arundo donax L. as a low-cost and promising biosorbent for the removal of crystal violet from aqueous media: kinetic, isotherm and thermodynamic investigations [PDF]

Chemical Review and Letters, 2019
In the present study, Arundo donax L was used as a low-cost biosorbent for the uptake of basic dye crystal violet (CV) from aqueous media. Systematic batch mode studies of adsorption of crystal violet (CV) on Arundo donax were carried out as a function ...

Ferromagnetic Properties of ZrZn$_2$

, 2005
The low Curie temperature (T_C approx 28K) and small ordered moment (M_0 approx 0.17 mu_B f.u.^-1) of ZrZn2 make it one of the few examples of a weak itinerant ferromagnet. We report results of susceptibility, magnetization, resistivity and specific heat

Isothermal and non‐isothermal consolidation of carbon fiber towpregs [PDF]

Polymer Composites, 2001
AbstractThe purpose of this work is to establish and validate a model to predict the isothermal and non‐isothermal consolidation behavior of unidirectional towpregs, made of carbon fibers and a thermoplastic polymer. A Finite Difference Method program was devised based on a set of analytical expressions developed in a previous work.

Molecular recognition on acoustic wave devices [PDF]

, 1992
Microporous thin films composed either of zeolite crystals embedded in sol-gel derived glass or of a molecular coupling layer, zeolite crystals and a porous silica overlayer, were formed on the gold electrodes of Quartz Crystal Microbalances (QCM). The

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Inverse gas chromatography of chromia. Part II. Finite surface coverage [PDF]

Journal of the Serbian Chemical Society, 2002
The interactions of n-hexane, benzene, chloroform, and tetrahydrofuran with dried (amorphous) chromia (I) and chromia heated at 1073 K (crystalline) (II), both obtained from a colloidal dispersion, and a commercially available chromia (III) were studied ...
