Diffuse Extragalactic Gamma Rays and Gamma Ray Bursts
, 1998 If gamma ray bursts produce a total energy of 10^54 ergs and this energy is concentrated on the high energy tail of the spectrum E> 1 TeV, then they may account for the observed diffuse extragalactic gamma ray emission for energies > 100 MeV. Such an energy could be released if the GRB's are produced by the burning of the total mass of a neutron ...

Surveys in High Energy Physics, 2001 Abstract The energy domain between 10 MeV and hundreds of GeV is an essential one for the multifrequency study of extreme astrophysical sources. The understanding of spectra of detected gamma rays is necessary for developing models for acceleration, emission, absorption and propagation of very high-energy particles at their sources and in space.

Advanced Functional Materials, EarlyView.Off‐centering of cations in pavonite‐structured Ag1.75InSb5.75Se11 (AISS) breaks crystal symmetry, inducing Rashba‐like band splitting and high band degeneracy, thus enhancing Seebeck coefficients. Soft bonds between off‐centered cations and Se atoms increase phonon scattering, achieving low lattice thermal conductivity (0.22 W m−1K−1 at 723 K). Doping

Advanced Functional Materials, EarlyView.Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for

A Close Look at the Local Structure of Functional Polymers: The Example of Poly(Vinylidene Fluoride)
Advanced Functional Materials, EarlyView.To accurately develop structure‐property relationships in functional macromolecules, it is increasingly important to consider the local chain arrangement in addition to long‐range order. It is demonstrated in the case of poly(vinylidene fluoride) that solid‐state nuclear magnetic resonance (NMR) spectroscopy can provide detailed insights into the local

Polar Pore Surface of Polyamide Membranes Enabling Efficient Solvent Mixture Separation
Advanced Functional Materials, EarlyView.A polyamide membrane with polar pore surfaces and relatively large pore is fabricated through interfacial polymerization between polyethyleneimine and trimesoyl chloride. Rapid separation of solvents with polarity differences is achieved by the synergistic effects of pore polarity and size sieving.
