Our recent investigations have revealed that substantially 2D melting transpires during the ELA process. In this paper, we first present the experimental finding that shows how this behavior at least stems intrinsically from the presence in the material of melt-prone grain boundaries and superheating-permitting Si-oxide interface. We also point out, and substantiate with numerical simulation results, that the manifested dimensionality of melting can figure in affecting (1) the energy utilization efficiency of the ELA method, as well as (2) the microstructural uniformity of the resulting polycrystalline materials.

URu2Si2 exhibits an anomalous peak in the nonlinear magnetic susceptibility at the hidden order transition. In order to investigate this anomaly, we conducted direct magnetization measurements and investigated the detailed angular dependence of the Si29 nuclear magnetic resonance Knight shift tensor. We find that the nonlinear magnetization is smaller than previously reported, and the analogous nonlinear Knight shift tensor is below the detection limit. Our results suggest that the magnitude of the anomalous peak is sample dependent.

We study the highly nonlinear wave dynamics of 1d tensegrity metamaterials, with a focus on the interaction of a compression solitary pulse with an interface between elastically stiffening and softening materials. We observe an anomalous response of the examined system, which is characterized by the propagation of a train of reflected compression solitary waves in the stiffening branch, and the transmission of a solitary rarefaction wave with oscillatory tail in the softening branch.

The study was done at Semarang, Central Java. The purpose of this study is to determine the variation of field susceptibility to landslide in the city of southern Semarang. Vulnerability includes physical, social, economic, and environmental ones. Each region has varying levels, types and characteristics of vulnerability. The results show that the vulnerability level of landslide is divided into 4 parts according to vulnerability indicator in Perka BNPB number 2 of 2012. The index categories were also modified into five categories from very low (1,00 to 1,40), low (1,41 to 1,80), moderate (1,81-2,20), high (2,21-2,40) and very high (2,41-3,0). Southern Semarang has moderate and high degree of vulnerability. The average vulnerability rate is in the high category with an index value of 2,20. The lowest average vulnerability is owned by Gunung Pati sub-District, while the highest vulnerability is owned by Candisari sub-District.

Bentonite added in bovine serum albumin (BSA) increases the thickness of the multilayer film. BSA-TA multilayer thin films are built on silicon surface. The growths of the multilayer thin films are investigated by ellipsometry. The surface morphologies of the multilayer thin films are characterised with scanning electron microscopy (SEM). Both BSA-TA and BSA-Bentonite (BSAB)-TA layer-by-layer (LbL) assemblies exhibit linear growth behaviour. For all multilayer films studied here, a large amount of tannic acid molecules is eluted during washing, indicating weak binding and reversible adsorption on BSA surface. Oppositely, BSA absorb irreversibly on TA-terminated layer.

All‐solid‐state sodium batteries (ASSSBs) with nonflammable electrolytes and ubiquitous sodium resource are a promising solution to the safety and cost concerns for lithium‐ion batteries. However, the intrinsic mismatch between low anodic decomposition potential of superionic sulfide electrolytes and high operating potentials of sodium‐ion cathodes leads to a volatile cathode–electrolyte interface and undesirable cell performance. Here we report a high‐capacity organic cathode, Na 4 C 6 O 6 , that is chemically and electrochemically compatible with sulfide electrolytes. A bulk‐type ASSSB shows high specific capacity (184 mAh g −1 ) and one of the highest specific energies (395 Wh kg −1 ) among intercalation compound‐based ASSSBs. The capacity retentions of 76 % after 100 cycles at 0.1 C and 70 % after 400 cycles at 0.2 C represent the record stability for ASSSBs. Additionally, Na 4 C 6 O 6 functions as a capable anode material, enabling a symmetric all‐organic ASSSB with Na 4 C 6 O 6 as both cathode and anode materials.
The strong spin-spin exchange interaction in some low-dimensional magnetic materials can give rise to a high group velocity and thermal conductivity contribution from magnons. One example is the incommensurate layered...
