An Interaction Model for Solid-Matrix Phosphorescence with Filter Paper via the Modulus of Filter Paper

Applied Spectroscopy, 1991
The experimental values of Young's modulus for filter paper samples were obtained as a function of temperature. These experimental modulus values for the filter paper samples, along with literature modulus values for regenerated cellulose and chromatography paper, were used to derive equations that relate Young's modulus values of filter paper to the ...

Determining surface tension of various liquids and shear modulus of paper using crumpling effect

Journal of Emerging Investigators, 2021
When a wet piece of paper is dried, it becomes crumpled. We termed this phenomenon the ‘Crumpling Effect’. The crumpling effect is commonly referred to as buckling of paper by water-color artists and can be caused by water or various other liquids and solutions.

Contactless measurement of the elastic Young's modulus of paper by an ultrasonic technique

Ultrasonics, 1999
Abstract The use of a non-contact ultrasonic technique for the characterization of the in-plane elastic Young's moduli of paper is considered. The determination of these moduli from A0 (fundamental antisymmetric plate wave mode) measurements, using the empirical technique introduced by Luukkala et al. (1971), is discussed: it is shown that the common

Response to “Comment on paper ‘The bulk modulus and Poisson's ratio of “incompressible” materials’”

Journal of Sound and Vibration, 2010
The incorrectness of the common assumption that rubbery polymers are incompressible does not preclude its yielding accurate determinations of the elastic modulus for nonlinear deformations.

A theory for the elastic modulus of paper

British Journal of Applied Physics, 1965
A review has been made of the previous attempts to formulate a theory for the elastic modulus of paper in terms of fibre properties. The suggestion is made that, by considering the case of uniaxial stress, previous authors have attempted a problem that is too complex for the present state of knowledge.

A New Test Method for the Determination of the Flexural Modulus of Spirally Wound Paper Tubes

Journal of Engineering Materials and Technology, 1992
A new static test method to determine the flexural modulus of spirally wound paper tubes is described. The experimental method is based on the standard three-point-bend procedure. The method requires testing the tube at multiple (two or more) span lengths.

Model for the Moisture Quenching of Solid-Matrix Phosphorescence via the Young's Modulus of Filter Paper

Applied Spectroscopy, 1995
Experimental Young's modulus values were obtained as a function of adsorbed moisture content for filter paper samples with no absorbed salt and with several different types of salt adsorbed on filter paper. The Young's modulus values were correlated with the room-temperature phosphorescence intensities and room-temperature phosphorescence lifetimes of ...

Correlation between macro- and nano-scopic measurements of carbon nanostructured paper elastic modulus

Applied Physics Letters, 2015
Extensive work has been done in order to determine the bulk elastic modulus of isotropic samples from force curves acquired with atomic force microscopy. However, new challenges are encountered given the development of new materials constructed of one-dimensional anisotropic building blocks, such as carbon nanostructured paper.

Elastic modulus of nanomaterials: resonant contact-AFM measurement and reduced-size effects (Invited Paper)

SPIE Proceedings, 2005
Resonant contact atomic force microscopy (resonant C-AFM) is used to quantitatively measure the elastic modulus of polymer nanotubes and metallic nanowires. To achieve this, an oscillating electric field is applied between the sample holder and the microscope head to excite the oscillation of the cantilever in contact with the nanostructures suspended ...

Realizing Ultrahigh Modulus and High Strength of Macroscopic Graphene Oxide Papers Through Crosslinking of Mussel‐Inspired Polymers

Advanced Materials, 2013
Covalently crosslinked graphene oxide papers (GOPs) with enhanced mechanical properties are prepared by a strategy involving crosslinking by means of intercalated polymers. The strength and modulus of the crosslinked GOPs increase by 115% and 550%, respectively, compared to the pristine GOPs. These results broaden the potential applications of graphene,
