Production of Lignin-Derived Functional Material for Efficient Electromagnetic Wave Absorption with an Ultralow Filler Ratio.

Industrial lignin, a by-product of pulping for papermaking fibers or of second-generation ethanol production, is primarily served as a low-grade combustible energy source. The fabrication of high-value-added functional materials with industrial lignin is still a challenge. Herein, a three-dimensional hierarchical lignin-derived porous carbon (HLPC) was prepared with lignosulfonate as the carbon source and MgCO as the template.

Evaluation of a new lithium complex hydride: a derivative of BH and NH for fast Li-ion conduction and H sorption.

A new ternary complex hydride is synthesized by the interaction between LiNH and LiBH. The crystal structure of this new hydride is tentatively indexed using an orthorhombic cell with a space group of 2 and lattice parameters of = 9.643 Å, = 6.

Ultrasonic characterization of multi-layered porous lithium-ion battery structure for state of charge.

A multi-layered porous finite element model of lithium-ion battery is proposed by using Voronoi polygons. The time domain simulation of ultrasonic transmission characteristics with different state of charge (SOC) are carried out, and the variation of acoustic parameters versus SOCs is explored. Then, in the experiment research, the ultrasonic transmission signals are obtained by employing piezoelectric ceramic transducers during the discharging step.

Bivalent Histone Modifications and Development.

Background: Development is an epigenetic regulation dependent event. As one pretranscriptional regulator, bivalent histone modifications were observed to be involved in development recently. It is believed that histone methylation potentially takes charge of cell fate determination and differentiation.

Enamel Regeneration in Making a Bioengineered Tooth.

Overall enamel is the hard tissue overlying teeth that is vulnerable to caries, congenital defects, and damage due to trauma. Not only is enamel incapable of self-repair in most species, but it is also subject to attrition. Besides the use of artificial materials to restore enamel, enamel regeneration is a promising approach to repair enamel damage.

Bivalent histone modifications during tooth development.

Histone methylation is one of the most widely studied post-transcriptional modifications. It is thought to be an important epigenetic event that is closely associated with cell fate determination and differentiation. To explore the spatiotemporal expression of histone H3 lysine 4 trimethylation (H3K4me3) and histone H3 lysine 27 trimethylation (H3K27me3) epigenetic marks and methylation or demethylation transferases in tooth organ development, we measured the expression of SET7, EZH2, KDM5B and JMJD3 via immunohistochemistry and quantitative polymerase chain reaction (qPCR) analysis in the first molar of BALB/c mice embryos at E13.
