Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam

open access: yesAdvanced Engineering Materials, EarlyView.
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

Near-infrared Variability Detected in the Young Star-forming Dwarf Galaxy SBS 0335-052E

open access: yesThe Astrophysical Journal
SBS 0335-052E is a young star-forming dwarf galaxy with a total stellar mass of M _*  ≲ 10 ^8 M _⊙ and an extremely low metallicity ( Z  ∼ 1/40 Z _⊙ ), which has long been considered to be devoid of an active galactic nucleus (AGN).

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

The Intermediate-mass Black Hole Reverberation Mapping Project: First Detection of Mid-infrared Lags in Prototypical Intermediate-mass Black Holes in NGC 4395 and POX 52

open access: yesThe Astrophysical Journal Letters
The search for robust evidence of intermediate-mass black holes (IMBHs) is crucial for understanding the black hole seeding process and the formation of supermassive black holes in the early Universe.

Geodesic Geometry of Black Holes [PDF]

open access: yes, 2006
The study of geodesics is of intrinsic significance in the study of the geometry of space-time. In this thesis null, space-like and time-like geodesics are studied in the case of the space-times of Schwarzschild, Reissner-Nordstrouml;m and Kerr black ...

Intermediate-Mass Black Hole Feedback in Dwarf Galaxies: a View from Cosmological Simulations [PDF]

open access: yes, 2020
Black holes are usually observed to be of stellar-mass or supermassive. By natural extension, there should be a population of Intermediate-Mass Black Holes (IMBHs: with mass between 100 to 106M☉) in the Universe; which has started to been observed.

Fully Additive Vertical Organic Electrochemical Transistors on Renewable and Compostable Substrates Enable Ultrasensitive Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Fully additive vertical organic electrochemical transistors (vOECTs) with channel‐length of 226 nm on a 50 µm compostable substrate achieve >106 current modulation and ∼36 mS transconductance. Ion‐selective integration enables 1.1 mA dec−1 sensitivity and 36 µm detection limit, highlighting a scalable platform for sustainable electronics and ...

Looking for Intermediate-Mass Black Holes [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2010
A discussion of the entropy of the universe leads to the suggestion of very many intermediate-mass black holes between thirty and three hundred thousand solar masses in the halo. It is consistent with observations on wide binaries as well as microlensing and considerations of disk stability that such IMBHs constitute all cold dark ...

Primordial intermediate mass black holes as dark matter [PDF]

open access: yesInternational Journal of Modern Physics A, 2020
Among particle theory candidates for the dark matter constituents. Axions and WIMPs are the most popular. In this paper, we discuss these then focus on our preferred astrophysical candidate, the Primordial Intermediate Mass Black Holes in the acronym DM[Formula: see text]=[Formula: see text]PIMBHs.
