Biomass DNA: An Emerging Building Block for Advanced Materials

open access: yesAdvanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Over 95% Optical Reflectance From Structurally Modulated All‐Biopolymer Multilayers

open access: yesAdvanced Materials, EarlyView.
A new dense–porous design turns ordinary polysaccharides into highly reflective photonic multilayers. Alternating dense pectin and porous cellulose nanofiber layers create strong refractive‐index contrast without inorganic or synthetic polymers, enabling nearly perfect visible reflection, high near‐infrared reflection, broadband metallic‐like colors ...

A Microcell for Stripping Analysis With Glassy Carbon and Mercury-Plated Glassy Carbon Electrodes

Analytical Letters, 1973
Abstract A microcell has been constructed for stripping analysis in solution volumes as low as 5 μl, employing a glassy carbon or mercury-plated glassy carbon working electrodes and a three electrode system. Using normal d.c. stripping techniques, as little as 100 picograms of mercury and 10 picograms of lead can be determined.

Ion Bombardment of Glassy Carbon

Vacuum, 2018
Abstract Glassy carbon has applications in the storage of high level nuclear waste. Irradiation of glassy carbon are thus of importance to investigate. The paper reviews some aspects for ion bombardment. Glassy carbon is categorised as an amorphous material with graphitic crystallites. Glassy carbon has a much lower density than graphite. It has been

Glassy Carbon: A Promising Material for Micro- and Nanomanufacturing [PDF]

open access: yesMaterials, 2018
When certain polymers are heat-treated beyond their degradation temperature in the absence of oxygen, they pass through a semi-solid phase, followed by the loss of heteroatoms and the formation of a solid carbon material composed of a three-dimensional ...

Glassy Carbon From Camphor — A Natural Source

open access: yesMaterials Chemistry and Physics, 1997
Glassy carbon has been synthesized for the first time by a simple pyrolysis experiment. The glassy carbon from camphor has been characterized by XRD, Raman, FTIR, ESR and SEM/AFM techniques.

Structure of Glassy Carbon

Nature, 1971
WHEN many polymers are pyrolysed, they change directly into a form of carbon which retains the original morphology without passing through a plastic phase. This type of carbon has a glass-like appearance and is referred to as a glassy carbon. It is hard and brittle, unlike the soft graphitic forms of carbon, and does not revert to these forms at high ...

Compressed Glassy Carbon: An Ultrastrong and Elastic Interpenetrating Graphene Network

open access: yesScience Advances, 2017
The compression of glassy carbon forms a series of lightweight, ultrastrong, hard, elastic, and conductive carbons.
