Graphite Bisulphate and Thermal Expanded Graphite from Lignin

Electrochemical Energetics, 2010
Pathbreaking studies of electrochemical graphite bisulphate synthesis from artificial graphite produced from hydrolyzed lignin and further production of high quality thermal expanded graphite are described. The studies show that any oxidation level can be achieved as well as over oxidized graphite may be produced at graphite bisulphate synthesis ...

Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

Advanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Heat Transfer Enhancement of a New Composite Adsorbent

Zhileng xuebao, 2013
Composite adsorbents of CaCl2/ activated carbon were prepared by charring and activating at high temperature from CaCl2 and fir crumbs. Thermal conductivity was improved by adding expanded graphite into composite adsorbent.

Porous materials in building energy technologies—a review of the applications, modelling and experiments [PDF]

, 2018
Improving energy efficiency in buildings is central to achieving the goals set by Paris agreement in 2015, as it reduces the energy consumption and consequently the emission of greenhouse gases without jeopardising human comfort.

Electronic structure of superconducting graphite intercalate compounds: The role of the interlayer state

, 2005
Although not an intrinsic superconductor, it has been long--known that, when intercalated with certain dopants, graphite is capable of exhibiting superconductivity.

The nature and strength of inter-layer binding in graphite

, 2009
We computed the inter-layer bonding properties of graphite using an ab-initio many body theory. We carried out variational and diffusion quantum Monte Carlo calculations and found an equilibrium inter-layer binding energy in good agreement with most ...
