Pressure-induced amorphization and polyamorphism in one-dimensional single crystal TiO2 nanomaterials

open access: yes, 2012
The structural phase transitions of single crystal TiO2-B nanoribbons were investigated in-situ at high-pressure using the synchrotron X-ray diffraction and the Raman scattering.

Experimental Investigation of Microbubble Evolution in the Liquivac Multiphase Flow Pump

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This paper aims to experimentally investigate the mechanisms of microbubble characteristics evolution within an axial pump. The findings will aid in assessing the pump performance by identifying the range of bubble sizes and comparing them with the threshold size (< 300 μm). This study also provides evidence supporting the use of such pumps as

Evolution of the structure of amorphous ice - from low-density amorphous (LDA) through high-density amorphous (HDA) to very high-density amorphous (VHDA) ice

open access: yes, 2005
We report results of molecular dynamics simulations of amorphous ice for pressures up to 22.5 kbar. The high-density amorphous ice (HDA) as prepared by pressure-induced amorphization of Ih ice at T=80 K is annealed to T=170 K at various pressures to ...

Arthroscopic subacromial decompression

open access: yesYonsei Medical Journal, 1992
A study group composed of 11 shoulders in 10 patients underwent arthroscopic subacromial decompression for impingement syndrome. There were no biceps tendon ruptures, acromioclavicular arthritis or glenohumeral instability. Eight men and two women ranging in age from 17 to 65 years (mean age 38.7) with dominant arm involvement in 9/10 were evaluated ...

Inline pvT Analysis for Precise Volume Dosing in Injection Molding: Addressing Variability in Recyclate Melts

open access: yesJournal of Applied Polymer Science, EarlyView.
Precise In‐line volumetric dosing despite varying material composition. ABSTRACT Precise volumetric dosing of polymer melts is essential for dimensional stability and mass consistency in injection‐molded samples, particularly when melt compressibility influences the effective volume delivered to the cavity. Conventional approaches rely on reference pvT
