The Supernova Gamma-Ray Burst Connection [PDF]

, 2006
The chief distinction between ordinary supernovae and long-soft gamma-ray bursts (GRBs) is the degree of differential rotation in the inner several solar masses when a massive star dies, and GRBs are rare mainly because of the difficulty achieving the ...

Verteporfin‐Mediated In Situ Nanovaccine Based on Local Conventional‐Dose Hypofractionated Radiotherapy Enhances Antitumor and Immunomodulatory Effect

Advanced Science, EarlyView.
Here gelatinase‐responsive methoxypolyethyleneglycol–PVGLIG–polycaprolactone (mPEG–PVGLIG–PCL) nanoparticles’ loading verteporfin (N@VP) is developed, enhancing radiotherapy via X‐ray‐triggered singlet oxygen generation. Combined with 2 Gy (gray, a radiation dose unit) irradiation, N@VP achieves antitumor efficacy comparable to 8 Gy, and also promotes ...

[Ag(μ‐en)][ReO4]: An Intermediate during Preparation of the Ethylene Epoxidation Catalyst

Zeitschrift für anorganische und allgemeine Chemie, Volume 648, Issue 23, December 13, 2022., 2022
Abstract Preparation of a catalyst for the ethylene oxide production requires impregnation of a porous corundum support with an aqueous silver ethylene diamine oxalate complex solution, to which among others NH4[ReO4] is added. Here we report on [Ag(μ‐en)][ReO4] that precipitates from such a mixture.

H2S Sensing with SnO2‐Based Gas Sensors: Sulfur Poisoning Mechanism Revealed by Operando DRIFTS and DFT Calculations

Angewandte Chemie, EarlyView.
The formation of sticky sulfite and sulfate surface species is identified as the root cause of the poisoning effect of H2S on SnO2‐based sensors by the compelling results and detailed analyses from operando DRIFTS experiments and density functional theory (DFT) calculations.

PROGENITOR MODELS OF THE ELECTROMAGNETIC TRANSIENT ASSOCIATED WITH THE SHORT GAMMA RAY BURST 130603B [PDF]

, 2013
An electromagnetic transient powered by the radioactive decay of r-process elements, a so-called kilonova/macronova, is one of the possible observable consequences of compact binary mergers including at least one neutron star.

Facile Fabrication of Large‐Area and High‐Quality Organic–Inorganic Hybrid Perovskite Ferroelectric Films Through Electrohydrodynamic Printing

Advanced Science, EarlyView.
In situ fabrication of large‐area, high‐quality organic‐inorganic hybrid perovskite ferroelectric (OIHPF) crystals and films via on‐demand electrohydrodynamic (EHD) printing modes. Abstract Traditional oxide ferroelectrics have long struggled to produce flexible, large‐area, and high‐quality thin films at low temperatures, despite their good ...

Vitamin D—A prominent immunomodulator to prevent COVID‐19 infection

International Journal of Rheumatic Diseases, Volume 26, Issue 1, Page 13-30, January 2023., 2023
Abstract COVID‐19 remains a life‐threatening infectious disease worldwide. Several bio‐active agents have been tested and evaluated in an effort to contain this disease. Unfortunately, none of the therapies have been successful, owing to their safety concerns and the presence of various adverse effects.

Constructing Large‐Area Oriented Covalent Organic Framework Based PN Heterostructure Films to Enhance Artificial Photosynthesis of H2O2

Angewandte Chemie, EarlyView.
We propose for the first time the concept of organic‐inorganic hybrid oriented PN heterostructured films to modulate the photocatalytic performance by constructing COF‐based PN heterostructured films, and our mechanistic studies confirm that oriented TAPB‐DMTA COFs based on thin films of PN heterostructures can provide the driving force to enhance the ...

Decameter Type III-Like Bursts [PDF]

YSC'14 Proceedings of Contributed Papers (eds. G. Ivashchenko, A. Golovin), Kyiv, Kyivskyi Universytet, pp. 68-72, 2007, 2007
Starting from 1960s Type III-like bursts (Type III bursts with high drift rates) in a wide frequency range from 300 to 950MHz have been observed. These new bursts observed at certain frequency being compared to the usual Type III bursts at the same frequency show similar behaviour but feature frequency drift 2-6 times higher than the normal bursts.

Thermonuclear (type-I) X-ray bursts observed by the Rossi X-ray Timing Explorer [PDF]

, 2006
We have assembled a sample of 1187 thermonuclear (type-I) X-ray bursts from 48 accreting neutron stars by the Rossi X-ray Timing Explorer, spanning more than ten years. The sample contains examples of two of the three theoretical ignition regimes and likely examples of the third.
