High uniformity Bessel beams with angle-controllable steering.

Bessel beams with controllable output angles and uniform intensity distribution along the propagation direction have critical applications in many fields. This paper introduces a novel method to generate high uniformity, high signal-to-noise ratio, and angle-controllable Bessel beams by combining a Fresnel zone plate (FZP) with an axicon. An apodizing phase axicon with an ideally fitted profile is used, with a Gaussian beam as the light source.

Enhancing the wear resistance of titanium alloys through the synthesis of layered double hydroxides combined with titanium nitride coatings.

Given the notoriously poor wear performance of Ti6Al4V (TC4) alloys, two types of MgAl layered double hydroxides (LDHs) were synthesized as lubrication additives. Systematic tribological tests were conducted to explore the performance of the TC4 alloy with these MgAl LDHs at varying concentrations in oil. It was found that, with increasing additive concentration, the wear resistance of TC4 significantly improved.

Response of riparian plant community to landscape matrix differs by taxonomic and functional diversity: Implications for the planning of riparian landscapes regulated by dams.

Local plant communities are embedded within the landscape matrix, and thus, diversity of these communities is largely determined by the spatial pattern of surrounding land-use. However, it is not yet clear how taxonomic and functional diversity within riparian plant communities respond differently to the landscape matrix at different scales, and whether and how these landscape-scale responses can be shaped by flooding conditions in the riparian landscape. This study is based upon field surveys of riparian plant communities in a total of 136 quadrats exposed to two different levels of flooding intensity along the reservoir formed by the Three Gorges Dam (TGD).

Robust Superamphiphobic Coating Applied to Grease-Proof Mining Transformer Components.

The iron core and heat sink in a mining transformer are susceptible to damage from oil spills or the harsh mine environment; the deterioration of oil products in the underground environment and transformers produce massive amounts of harmful liquid substances, which may lead to unnecessary economic losses in drilling engineering.
