Proline Spray Relieves the Adverse Effects of Drought on Wheat Flag Leaf Function.

Drought stress is one of the key factors restricting crop yield. The beneficial effects of exogenous proline on crop growth under drought stress have been demonstrated in maize, rice, and other crops. However, little is known about its effects on wheat under drought stress.

Croton tiglium essential oil compounds have anti-proliferative and pro-apoptotic effects in A549 lung cancer cell lines.

As a traditional Chinese medicine, Croton tiglium has the characteristics of laxative, analgesic, antibacterial and swelling. This study aimed to analyze the chemical composition of C. tiglium essential oil (CTEO) extracted from the seeds of C.

Two new diterpenoids with their antiproliferative activities from the supercritical fluid extraction of root.

Supercritical fluid extraction was applied to obtain the lower polarity extracts from roots, and chemical investigation of which led to the isolation and identification of two new diterpenoids, named crassifolius P () and crassifolius Q (). anti-proliferative activities of compounds and on A549, Hep-G2 and Hela tumor cell lines were evaluated. The two new compounds exhibited obvious selectivity to tumor cells with IC values ranging from 20.

Linearly thermal-tunable near-infrared ultra-narrowband metamaterial perfect absorber with low power and a large modulation depth based on a four-nanorod-coupled a-silicon resonator.

The bandwidths of thermal-tunable metamaterial perfect absorbers (MPAs) based on the phase change materials such as GeSbTe and VO are usually hundreds of nanometers at near-infrared frequency. Amorphous silicon (a-Si) provides the approach to achieve linearly thermal-tunable ultra-narrowband MPAs, if the absorption band is narrow enough. Four-nanorod-coupled a-Si resonators are proposed in this Letter.

Theoretical excitation of 2-D (1, 1) cavity mode with asymmetric sword-shaped notched square resonators for metamaterial perfect multiband absorbers in infrared range.

1-D cavity modes in 1-D resonators, such as strips, have been used to design multiband metamaterial perfect absorbers. As for 2-D resonators, such as squares and crosses, most studies still focus on exciting the 1-D cavity modes. In this paper, a symmetry-breaking idea is proposed for 2-D cavity mode excitation.
