Both Nuclear Magnetic Resonance (NMR) and X-Ray absorption spectroscopies characterize local order around the observed nuclei. With the recent progresses of 71Ga solid state NMR, it has become possible to take advantage of the complementary information that can be obtained using these two methods. This opens the possibility of a more thorough description of the first coordination shells of Ga in oxide. We present and discuss the example of an Al-, Ga-based catalyst.

Hydrogen gas holds immense promise as a clean fuel source, yet its widespread adoption faces significant challenges in storage and transportation due to its gaseous and highly flammable nature. An increasingly attractive approach to overcoming these limitations involves reacting aluminum (Al) blocks with water to produce hydrogen, providing an alternative distribution mechanism in which Al blocks can be used as "hydrogen storage" for on-demand production at any location. However, current methods suffer poor hydrogen production rates and yields, primarily influenced by the limited contact area between Al and the catalyst, such as Ga-based room-temperature liquid metal.

Liquid metals (LMs) illustrate a fantastic future. Thus, great endeavors are made to earn a comprehensive understanding of this fluid and carve it into a niche. Herein, by revisiting the combination of Ga-based LMs and aluminum (Al), a new phenomenon, namely the disintegration of LM films on encountering water, is identified.

Novel anticancer strategies reduce side effects on healthy tissues by elevating the lethal abilities of cancer cells. The development of effective particles with good bioavailability and selectivity remains problematic. For undesirable features, green chemistry is used to synthesize the best compounds, or natural-based particles are improved.

Cold rolling has been used as a real-time surface oxidation control method to create colored strips on flexible substrates. By controlling the extrusion rate in real time, a variety of colored strips have been fabricated on Ga-based liquid metal (LM) strips. X-ray photoelectron spectroscopy (XPS) analysis shows that the surfaces of the colored strips, which were obtained through extrusion rate control of LM-Al, consist primarily of metal oxide composites, including GaO, GaO, AlO, SnO, and InO.
