Patterned Surface Energy for Modulating Solid-Liquid Interfacial Properties.

Surface energy, as an intrinsic property of solids, plays a crucial role in modulating the characteristics of solid surfaces, especially of the solid-liquid interface. Due to inevitable processes such as surface adsorption or contamination, the surface energy of practical solids is usually nonuniform. However, if this nonuniformity is rationally designed and effectively utilized, it is capable of endowing great potential for liquid manipulation.

Microscopic Mechanism of the Intercalation Behavior of AlCl4- in Graphite Cathode Materials of Aluminum-ion Batteries.

Rechargeable aluminum-ion batteries with graphite as cathode material are highly attractive for energy storage due to their low cost, high abundance, and high capacity. Although some techniques have been employed to investigate intercalation/deintercalation behavior of AlCl4- in graphite materials, the microscopic mechanism remains ambiguous and controversial, leading to a question that needs to be answered. Therefore, direct and in-situ characterization of nanoscale variations in the z direction is a reliable avenue to finding the answer to the intercalation stage mechanism.

Printing Multi-Layered Functional Devices Using One Stamp with Programmable Surface Energy.

Beyond its role in cultural communication, printing technology has emerged as one of the most important approaches to distributing and patterning functional materials for advanced manufacturing.

Preclinical Positron Emission Tomography (PET) of Prosthetic Joint Infection Using a Nitro-Prodrug of 2-[F]F--Aminobenzoic Acid ([F]F-PABA).

Deep-seated bacterial infections are difficult to detect and diagnose due to the lack of specific clinical imaging modalities.

PET imaging demonstrated that the uptake of 2-[F]fluoro-4-nitrobenzoic acid in a clinically relevant prosthetic joint infection model was up to ∼4-fold higher in the infected joint compared to the contralateral joint.

Effect of liquid level monitor gas injection point size on information source amplitude-frequency characteristics.

In order to analyse the effect of the injection point size of the CBM (Coalbed Methane) well level monitor on the amplitude and frequency of pressure pulsations in the wellhead manifold, numerical simulations and experiments were carried out to investigate the effect of different injection point sizes on the amplitude and frequency of pressure pulsations downstream of the sudden expansion structure. Using compressed air as the fluid and the size of the injection point as the variable, the amplitude and frequency of pressure pulsations at different locations downstream of the sudden expansion structure were tested. The results show that the pressure pulsation amplitude is affected by the size of the injection point, and the larger the injection point is, the larger the pressure pulsation amplitude is; the size of the injection point has less influence on the pressure pulsation frequency downstream of the protruding and expanding structure, and the pressure pulsation frequency at 0.
