A well attached coating of nitrogen-functionalised carbon nanofibers (N-CNFs) has been prepared on the walls of cordierite monolith channels. It is formed via concurrent decomposition of ethane and ammonia catalysed by nickel nanoparticles dispersed on alumina coated cordierite monolith. N-CNF/monoliths synthesis employing several growth temperatures and NH(3) compositions was exhaustively char...

We provide a characterization of Horn cores for formulas in conjunctive normal form (CNF) and, based on it, a novel algorithm for computing Horn cores of disjunctions of Horn CNFs that has appealing properties (e.g., it is polynomial for a bounded disjunction). Furthermore, we show that recognizing the Horn envelope of a disjunction of two Horn CNFs is intractable, and that computing a compact ...

Carbon nanofibers (CNFs) have been incorporated into poly(methyl methacrylate) (PMMA) through electrospinning. The resulting micro- and nanofibers have been characterized by Scanning Electron Microscopy (SEM), which confirmed fiber formation and demonstrated a core-sheath structure of the PMMA fibers. Thermogravimetric Analysis (TGA) was used to obtain the thermal properties of the materials, i...

We introduce principles 2VR and 2VR which imply reflection for, respectively, the CNFs and the narrow CNFs refutable in the depth-1 propositional LK system PK1. We give a polynomial-size refutation of their negations 2VR and 2VR in the system PK1 and show an exponential lower bound on the size of their resolution refutations. We conjecture that they have no small Res(log) refutations; this woul...

A Boolean formula in conjunctive normal form (CNF) is called matched if the system of sets of variables which appear in individual clauses has a system of distinct representatives. We present here two results for matched CNFs: The first result is a shorter and simpler proof of the fact that Boolean minimization remains complete for the second level of polynomial hierarchy even if the input is r...

Craniofrontonasal syndrome (CNFS) is an X-linked disorder caused by mutations in the EFNB1 gene in which, paradoxically, heterozygous females are more severely affected than hemizygous males. In this paper, the clinical and molecular studies of a female subject with CFNS are described. A novel de novo c.473T>C (p.M158T) mutation in exon 3 of EFNB1 was demonstrated in this patient. The M158 resi...

Developing the polymer-based thermal interface materials (TIMs) is one of most promising approaches to address heat accumulation along with functionalization, integration, and miniaturization modern electronics, while it still a great challenge balance conductivity mechanical properties. In this article, Fe ion-anchored graphene (FeG) successfully fabricated by facile in situ reduction oxide (G...

Abstract The essence of morphological design has been a fascinating scientific problem with regard to understanding biological mineralization. Particularly shaped amorphous silicas (plant opals) play an important role in the vital activity rice plants. Although various organic matters are associated silica accumulation, their detailed functions shape-controlled mineralization process have not s...

Polyacrylonitrile-based carbon nanofibers (PAN-based CNFs) have great potential to be used for dioxide (CO2) capture due their excellent CO2 adsorption properties. The porous structure of PAN-based CNFs originates from turbostratic structure, which is composed numerous disordered stacks graphitic layers. During the carbonization process, internal arranged toward ordered significantly influences...
