Introduction Uniform ordered nanoporous carbons (ONC) have many useful applications in separation, electrode materials and catalytic reactions owing to their outstanding advantages of high specific surface area, well-defined narrow pore size distribution, thermal and chemical resistance[1-3].
Conclusions Ordered nanoporous carbon (ONC) materials were successfully synthesized from sucrose via SBA-15 hard template.

Introduction The rare-earth (RE) doping of Si and Si-related materials [1-8] in the last years has been extensively studied for the development of light-emitting devices in the Si-based optoelectronics initiated by the reports on the photoluminescence (PL) and electroluminescence (EL) centered at around 1.54 μm of Er3+ (4I13/2→4I15/2) in Si [9].

The top-seeded melt-growth (TSMG) process has been widely employed to produce single grain materials, allowing the batch production of RE-123 materials [7].
IG-processed materials show uniform 211 secondary phase particles in the Y-123 matrix.
Former studies [7-11] clarified that the IG-processed YBa2Cu3Oy “Y-123” materials exhibit higher Jc values than those of melt-textured Y-123 materials.
For magnetization measurements, the specimens were cut from bulk materials at 2 mm below the seed crystal.

It will increase to 47% if the energy wasted in building materials production process (Accounting for 17% of total energy consumption society), which means construction-related energy will account for 47% of the total social energy consumption.
The high-performance VIP vacuum insulation panels were installed inside the wall of Bamboo House, and phase change materials were applied on the interior wall to maintain the indoor temperature, creating a comfortable temperature feeling.
The highest level of vacuum insulation and hollow triple glazing were adopted in design of windows, while the underground ventilation tubes were coated with phase change materials.
