The High-resolution Fe K Spectrum of Cygnus X-3

open access: yesThe Astrophysical Journal
We analyze features of the Fe K spectrum of the high-mass X-ray binary Cygnus X-3. The spectrum was obtained with the Chandra High Energy Transmission Grating Spectrometer in the third diffraction order. The increased energy resolution of the third order

Harnessing Outer Space for Improved Electrocaloric Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

Studying the frequency spectrum of acoustic emission signals by the infradyne transform method

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки
Background. The process of formation and development of microcracks in the walls of a tank with liquefied hydrocarbons can inevitably lead to a breach of tightness and, as a consequence, to the creation of a fire-hazardous situation and, yes, an ...

Self‐Cascade Catalytic Reaction–Assisted Apoptosis/Calcicoptosis/Ferroptosis Induction with Microsphere‐Aggregated Hydrogels in Triple‐Negative Breast Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Hyaluronic acid‐dopamine‐based intra‐crosslinked microsphere including cisplatin (HPC MS) is fabricated by spray‐drying and calcium/iron ions are introduced for interparticle crosslinking. Designed microsphere‐aggregated hydrogel (MAH) system including cisplatin/CaO2/FeSO4 can provide apoptosis/calcicoptosis/ferroptosis‐mediated chemo/cascade ...

Interfacial Contact Engineering Enables Giant‐Performance Semiconductor Nanomembrane Optoelectronic Devices

open access: yesAdvanced Functional Materials, EarlyView.
This work investigates modifying interfacial contacts in realizing giant‐performance semiconductor nanomembrane optoelectronics. Strategies, including surface reaction and buffer layer work‐function modulation, are explored to boost the Schottky barrier. An emerging material of YbOx is utilized for near‐ideal Ohmic contact.
