Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
Advanced Functional Materials, EarlyView.A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Advanced Functional Materials, EarlyView.By mimicking the ion‐accelerating effect of ion channel receptors in neuron membranes, a biomaterials‐based ionic hydrogel (BIH) is developed, which offers a high ionic conductivity of 7.04 S m−1, outperforming conventional chitosan, cellulose, agarose, starch, and gelatin based ionic hydrogels.

Spheroidization of glass powders for glass ionomer cements
Biomaterials, 2004Commercial 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 ...

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, 1974Measurement 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, 1999At 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, 1988Abstract 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, 2019Abstract 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

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, 1981Sintering 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
