By taking advantage of the elevation domain, three-dimensional (3-D) multiple input and output (MIMO) with massive antenna elements is considered as a promising practical technique for fifth Generation mobile communication system. So far, 3-D MIMO mostly studied by simulation few field trials have been launched recently. It still remains unknown how much does meet our expectations in versatile scenarios. In this paper, we answer based on measurements 56 × 32 at 3.5 GHz 100-MHz bandwidth...
Abstract The anomalous Hall effect (AHE) occurs in magnetic systems and also unexpectedly non‐magnetic materials adjacent to insulators via the heterointerface interactions. However, AHE heterostructures induced by proximity remains quite weak, restricting their practical device applications. Here, a large intrinsic with resistivity of 114 nΩ cm at 5 K noncoplanar Cr Te 6 /Pt is reported. This record‐high value among all insulators/heavy metal heterostructures. A reversal signal due...
This paper presents a continuation of our earlier research on the crystallization and solid-state structure polylactide copolymers. The focus here is random copolymers containing predominately l-lactide small amounts (1.5, 3, 6%) d-lactide. As expected, degrees crystallinity spherulite growth rates decrease substantially with increasing d-lactide content in importance defect arrangement (isolated vs paired stereochemical defects) was demonstrated by comparison to l-lactide/meso-lactide At...
Although the microporous membrane prepared based on melt stretching mechanism has been commercialized for more than 20 years, formation process from initial lamellae structure to final fiber connecting bridges and pores is still unclear. In this work, clarify transformation mechanism, in situ SAXS WAXS were carried out during hot at 130 °C 100%. The scattering patterns annealed film, cold stretched film 20% (stretched room temperature), heating also collected. preparation technology was...
A strategy of dual-crosslinking side chains with an asymmetric chain structure can facilely fulfill robustly self-healable and re-dissolvable polysiloxane elastomer, ensuring the large-scale applications in recyclable flexible devices adhesives.
The modification of thermoplastic polymers is frequently impeded by the inherent contradiction between their toughness and strength. In this study, an effective strategy to significantly improve mechanical properties ductile simply adding a complimentary rigid polymer introduced. This work uses semi-crystalline aliphatic polyketone (POK) as matrix material small quantity polymethyl methacrylate (PMMA) polymer, through establishing molecular chain entanglements at interface produce POK/PMMA...
Abstract Rationally designing the electrolyte system toward improving electrochemical performance, especially rate capability, of sodium ion batteries (SIBs) is very important for accelerating their large‐scale commercialization. Herein, it shown that by refining molar ratio two ether solvents, namely dimethoxyethane (DME) and 2‐methyl tetrahydrofuran (MeTHF), a binary solvent forms solvation structure facilitates high charge/discharge hard carbon (HC) electrodes. It demonstrated boosted...
Anthropogenic noise pollution is increasingly acknowledged as a major threat to marine ecosystems, especially for sound-sensitive species, such the large yellow croaker (Larimichthys crocea). While effects of underwater on fish behavior and physiology have been well-documented, its influence oxygen metabolism across varying temperatures remains poorly understood. This study examines impact boat consumption rate (OCR) juvenile croakers at different temperatures, key factor in their metabolic...
Abstract Over the past decade, topological insulators have received enormous attention for their potential in energy‐efficient spin‐to‐charge conversion, enabled by strong spin‐orbit coupling and spin‐momentum locked surface states. Despite extensive research, conversion efficiency, usually characterized spin Hall angle ( θ SH ), remains relatively low at room temperature. In this work, pulsed laser deposition is employed to fabricate high‐quality ternary insulator (Bi 0.1 Sb 0.9 ) 2 Te 3...
Herein, polylactic acid cast films were prepared with different melt-draw ratios <italic>via</italic> an extrusion casting process. The oriented structure appeared at first and then a chi crystal was formed higher MDR.
The orientation and crystallization during melt stretching were characterized, their influence on the lamellar morphology stretched polypropylene pore structure was clarified. During stretching, MDR range from 40–200 could be divided into two regions. In region I, below 120, crystalline transformed ellipsoid spherulites to lamellae structure, orientation, elastic recovery, lateral dimension enhanced. porosity of corresponding microporous membrane increased 37.8–45.5%. II, with increasing...
The influence of annealing temperature on the lamellar and connecting bridge structure stretched polypropylene microporous membrane was investigated using small-angle X-ray scattering, temperature-modulated differential scanning calorimetry electron microscopy. It is found that with increasing from 105 to 145 °C, main lamella melting peak combines bridges a uniform pore arrangement obtained in membrane. annealed thickness increased improved, due occurrence recrystallization during annealing....

The influence of heat-setting temperature on the stress–strain curves, differential scanning calorimetry (DSC) curves and properties a stretched polypropylene microporous membrane was studied. It found that with an increase temperature, plastic plateau region in melting endotherm DSC became apparent. permeability porosity firstly increased to 145 °C then decreased. pore structure arrangement showed similar changing trend. On one hand, higher could decrease shrinkage membrane. other...
Molybdenum disulfide (MoS 2 ) with two‐dimensional (2D) lamellar structure was functionalized melamine‐cyanuric acid (MCA) hybrids via a facile way. A core‐shell composite particle (MoMA) obtained. Acting as one kind of synergistic flame retardant, it mixed traditional intumescent retardant (IFR) to prepare the poly(lactic acid) composites by melt blending.
