Most crystalline inorganic materials, except for metals and some layer exhibit bad flexibility because of strong ionic or covalent bonds, while amorphous materials usually display poor electrical properties due to structural disorders. Here, we report the simultaneous realization extraordinary room temperature thermoelectric performance in Ag2Te1-x S x -based through amorphization. The coexistence main phase crystallites results exceptional ultralow lattice thermal conductivity. Furthermore,...
Abstract Following the Materials Genome Initiative project, materials research has embarked a new paradigm centered around material repositories, significantly accelerating discovery of novel materials, such as thermoelectrics. Thermoelectric capable directly converting heat into electricity, are garnering increasing attention in applications like waste recovery and refrigeration. To facilitate this emerging paradigm, we have established Hub with Three‐Dimensional Structures (MatHub‐3d)...
Abstract Objectives The aim of this work was to investigate the alteration in P-glycoprotein (P-gp) at blood–brain barrier (BBB) after middle cerebral artery occlusion (MCAO) rats. Methods Permanent MCAO verified via 2,3,5-triphenyltetrazolium staining and hematoxylin-eosin staining. expression P-gp, matrix metalloproteinase-2 (MMP-2), MMP-9, claudin-5, tumour necrosis factor-α (TNF-α) nitric oxide synthase (NOS) BBB evaluated using western blot or immunostaining analysis. content...
In this work, A2Cu3In3Te8 (A = Cd, Zn, Mn, Mg) thermoelectric chalcogenide materials, exhibiting intrinsically complex structures, low lattice thermal conductivities, high Seebeck coefficients, and thus promising properties, are designed explored, by a systematic structure search surpassing the conventional doping carrier concentration optimizing approach. The newly introduced alloying elements A found to uniformly distribute at 4a 4b sites which solely occupied Cu in cation sublattice of...
Constantan (Cu–Ni alloy) is widely used in the field of thermocouples due to its excellent thermoelectric and mechanical properties. To broaden application area, intrinsically high thermal conductivity intentionally suppressed with aim increase figure-of-merit (ZT) eventually energy conversion efficiency. All-scale hierarchical architectures including point defect, second phase, nanocomposite, micropore are realized Cu–Ni-based alloys, leading significant reduction from 18.14 3.23 W m–1 K–1...
Abstract The damage layer of a W (100) crystal irradiated with 120 eV hydrogen ions at fluence up to 1.5 × 10 25 /m 2 was investigated by scanning electron microscopy and conductive atomic force (CAFM). periodic surface degeneration the temperature 373 K formed increasing fluence. Observations CCD camera CAFM indicate existence ultrathin layers due low-energy H irradiation. can contain high density nanometer-sized defects, resulting in thermal instability atoms layer. Our findings suggest...
Abstract It has been widely recognized that glutamate (Glu)‐induced cytotoxicity, intracellular calcium overload and excessive free radical production are the key players in development progression of ischemic brain injury. Since MK‐801, an antagonist N‐methyl‐ d ‐aspartate (NMDA) receptor, showed many adverse reactions hampered its clinical applications, safe effective agent for treatment cerebral ischemia is eagerly required. This study was to investigate effects N 1...
Interface engineering has attracted extensive attention in the field of thermoelectric materials to achieve high conversion efficiency heat into electricity by disrupting thermal transport. However, work on interfacial decoration, understanding formation extrinsic boundaries, and their influence local properties half-Heusler compounds is still limited. Here we report a feasible strategy induce decoration excessively doping Ni an 18-electron prototype TiCoSb system. Ni-Decorated grain...

The effect of uniaxial strain on the thermoelectric (TE) conversion efficiency puckered monolayer arsenic antimonide (SbAs) is explored based density function and Boltzmann transport equation (BTE) theories. lattice thermal conductivity ( κ l ) can be sharply lowered through tensile strain. Taking a + 3.25% as an example, along armchair (AC) direction at 300 K decreases almost three times than that without strain, which ascribed to low phonon group velocity, large Grüneisen parameter, high...
