Novel metastable metallic and semiconducting germaniums [PDF]

, 2012
By means of ab initio metadynamics runs we explored the lower-pressure region of the phase diagram of germanium. A monoclinic germanium phase with four-membered rings, less dense than diamond and compressible into \beta-tin phase (tI4) was found.

Organogermanium, Ge-132, promotes the clearance of senescent red blood cells via macrophage-mediated phagocyte activation

Heliyon
Red blood cells (RBCs) are renewed in a cyclic manner. Aging RBCs are captured and degraded by phagocytic cells, and heme metabolic pigments are subsequently excreted in feces.

Leaching behavior of germanium from germanium-rich lignite: A further comprehension of its occurrence state

Fuel Processing Technology
Germanium, a critical metal used in many strategy fields, is widely acknowledged as organic affinity. Germanium is main occurred in the humus of lignite, but its exact occurrence state remains unclear. In this work, various methods were employed to leach

Germanium, Arsenic, and Selenium Abundances in Metal-Poor Stars

, 2012
The elements germanium (Ge, Z=32), arsenic (As, Z=33), and selenium (Se, Z=34) span the transition from charged-particle or explosive synthesis of the iron-group elements to neutron-capture synthesis of heavier elements.

Mineralization characteristics and exploration progress of germanium resources in Chinese coal

Meitan kexue jishu
Germanium, as a typical scarce element and important strategic metal, is widely used in fields such as optoelectronics, semiconductors, and chemicals. The exploration and development of germanium resources are therefore of great significance.

The anti‐CRISPR protein AcrIE8.1 inhibits the type I‐E CRISPR‐Cas system by directly binding to the Cascade subunit Cas11

FEBS Letters, EarlyView.
In this study, we present the structure of AcrIE8.1, a previously uncharacterized anti‐CRISPR protein that inhibits the type I‐E CRISPR‐Cas system. Through a combination of structural and biochemical analyses, we demonstrate that AcrIE8.1 directly binds to the Cas11 subunit of the Cascade complex to inhibit the CRISPR‐Cas system.

Organogermanium: Potential beneficial effects on the cardiovascular system

Physiological Reports
Organogermanium, especially poly‐trans‐[(2‐carboxyethyl)germasesquioxane] (Ge‐132), has been known to enhance immune‐modulatory activities. However, the in vivo and in vitro evidence accumulated over the last 20 years reveals that Ge‐132 has unique but ...

Germanium: distribution, migration and accumulation in the natural environment

Науковий вісник Львівського національного університету ветеринарної медицини та біотехнологій імені С.З. Гжицького. Серія: Сільськогосподарські науки, 2023
In this paper we attempt to generalize information published in the scientific literature about the distribution, migration and accumulation of chemical forms of germanium in the natural environment, with the main attention paid to the content of this ...
