Medical Fabrics with Non‐Antibiotic, Supramolecular Antimicrobial Coatings: A Preventive Approach to Combat Biofilm Formation and Bacterial Dissemination

Advanced Healthcare Materials, EarlyView.
The study presents an antibiotic‐free strategy using medical fabrics coated with supramolecular assemblies of polyarginine and hyaluronic acid. These coatings showed strong antimicrobial and anti‐biofilm activity in vitro and in vivo, achieving major bacterial load reductions, including against MRSA.

Spheroidization of glass powders for glass ionomer cements

Biomaterials, 2004
Commercial angular glass powders were spheroidized using both the flame spraying and inductively coupled radio frequency plasma spraying techniques. Spherical powders with different particle size distributions were obtained after spheroidization. The effects of spherical glass powders on the mechanical properties of glass ionomer cements (GICs) were ...

Aging of glass powder surface

Journal of Non-Crystalline Solids, 2015
Abstract Glass powder (GP) obtained by grinding waste bottle glass has been recently introduced in construction materials as a supplementary cementing material (SCM). The behavior of SCMs strongly depends on surface chemistry, which governs their reactivity.

Luminescence of powdered uranium glasses*

Journal of the Optical Society of America, 1974
Measurement of cathodoluminescence and photoluminescence efficiencies in powdered borosilicate glasses having different particle size and different uranium content. Excitation with 100 to 350 keV electrons and with 253.7 nm light was found to produce identical absolute radiant exitance spectra in powdered samples.

Proton glass freezing in hydrated lysozyme powders

Physical Review E, 1999
At room temperature, the dielectric relaxation of hydrated powder of the protein lysozyme is known to be due to protons migrating between ionized side chains. A recent study of this relaxation at lower temperatures suggested a behavior typical of proton glasses.

Explosive compaction of metallic glass powders

Materials Science and Engineering, 1988
Abstract Rapidly quenched materials, produced as powders, flakes or thin strips, can be consolidated by making use of the high pressures of detonating explosives. The underlying process is that of a shock front proceeding at a velocity greater than the sonic velocity of the material, which compacts the material instantaneously.

Metal to glass sealing using glass powder: Ion induced crystallization of glass

Materials Chemistry and Physics, 2019
Abstract In this study, we investigated bonding mechanism of a metal foil with glass substrate. We used glass powder to enhance surface area and promote diffusion in the interface. The metal/glass powder/glass assembly was annealed at 600 °C for 1 h and adhesion process was monitored. Using transmission electron microscope, element mapping, Raman and

Powder From the Glass Jar

Archives of Surgery, 1997
In 1949-1950, as Fellow on the Tumor Service of the Department of Surgery at Yale University, New Haven, Conn, I was responsible for administration of nitrogen mustard to those patients for whom such therapy was indicated. To do so, I went to the surgical laboratory, as had Fellows before me, and measured on a balance the proper amount of nitrogen ...

Sintering of Glass Powder Compacts

Transactions of the Indian Ceramic Society, 1981
Sintering of two glasses (i) CaO 23.0%, Al2O3 15.0% and SiO2 62.0% and (ii) CaO 52.0%, Al2O3 41.5% and SiO2 6.5% with eutectic temperatures 1170° and 1335°C respectively has been carried out at 700°, 800°, 850° and 900°C. Effect of temperature and composition on the viscosity of glasses has been studied. Variations in viscosity with rise in temperature

Processes for silica glass powder sintering

Journal of Non-Crystalline Solids, 1989
Abstract Processes for silica glass powder sintering have been investigated in order to obtain glass-ceramics materials with definite physico-chemical properties. The influence of additions (BN and BPO 4 ) on the mechanism of sintering and structure of silica glass ceramics has been studied using X-ray diffraction, IR-spectroscopy, optical and ...
