Fresh insights into structure-function-integrated self-antibacterial Cu-containing Al alloys: giving Al alloys a new function.

Contact infection by bacteria and viruses is a serious concern to human health. The increasing occurrence of public health problems has stimulated the urgent need for the development of antibacterial materials. Al alloys are the fastest-growing mass-produced material group, a prerequisite for the lightweight design of vehicles, food containers and storage, as well as civil-engineering structures.

The Antennal Sensilla and Expression Patterns of Olfactory Genes in the Lower Termite Reticulitermes aculabialis (Isoptera: Rhinotermitidae).

The insect olfactory system plays pivotal roles in insect survival and reproduction through odor detection. Morphological and physiological adaptations are caste-specific and evolved independently in workers, soldiers, and reproductives in termites. However, it is unclear whether the olfactory system is involved in the division of labor in termite colonies.

Endocuticle is involved in caste differentiation of the lower termite.

Caste differentiation in termites is one of the most conspicuous examples of facultative polyphenism in animals. It is clear that specific cuticular formation occurs in hard exocuticles during caste differentiation. However, the developmental pattern of the soft endocuticle in the differentiation pathways of castes is unknown.

A triphenylamine-based colorimetric and fluorescent probe with donor–bridge–acceptor structure for detection of G-quadruplex DNA.

In this Letter, three triphenylamine-based dyes (TPA-1, TPA-2a and TPA-2b) with donor–bridge–acceptor (D–p–A) structure were designed and synthesized for the purpose of G-quadruplexes recognition. In aqueous conditions, the interactions of the dyes with G-quadruplexes were studied with the aim to establish the influence of the geometry of the dyes on their binding and probing properties. Results indicate that TPA-2b displays significant selective colorimetric and fluorescent changes upon binding of G-quadruplex DNA.
