Non-isothermal TGA study on the combustion reaction kinetics and mechanism of low-rank coal char
RSC Advances, 2018 In this paper, the combustion reaction kinetics of pyrolysis char of low-rank coal is studied by thermal analysis technology. For the combustion process of the char at different heating rates, the reaction kinetic parameters were calculated by three ...

Novel Functional Materials via 3D Printing by Vat Photopolymerization
Advanced Functional Materials, EarlyView.This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Thermogravimetric characteristics of char obtained at high heat rate
Ingeniería e Investigación, 2009 Coal reactivity during combustion is determined by the thermogravimetric characteristics of char. The thermogravimetric charac- teristics of chars obtained in a drop-tube furnace were studied in this work.

Advanced Materials, EarlyView.A linker‐desymmetrization‐modulator‐compensation (LDMC) strategy for constructing structurally diverse Zr‐MOFs is reported. This approach reduces linker symmetry to create defects in Zr‐clusters, which can be compensated for by modulator coordination. Using this approach, we synthesized PCN‐1005 and PCN‐1006, featuring unprecedented Zr‐clusters. In PCN‐

Peptide‐Induced Ferroelectricity in Charge‐Transfer Supramolecular Materials
Advanced Materials, EarlyView.Bio‐inspired supramolecular charge‐transfer amphiphiles self‐assemble into nanoribbons in water, where peptide chirality‐induced symmetry breaking generates robust ferroelectricity across multiple systems. These water‐processable organic ferroelectrics also enhance neuronal outgrowth and electrophysiological maturity, offering a versatile strategy for ...

Evaluation of the energy transfer in the char zone during ablation. Part 2: In-depth response of ablative composites, volume 1 [PDF]
The decomposition of ablative composites is described along with the transport phenomena of pyrolysis gases which result from the decomposition of these plastics as they flow through the porous char of char-forming ablators.

Veronesean embeddings of dual polar spaces of orthogonal type
, 2013 Given a point-line geometry P and a pappian projective space S,a veronesean embedding of P in S is an injective map e from the point-set of P to the set of points of S mapping the lines of P onto non-singular conics of S and such that e(P) spans S.
