An efficient process for thermal atomic layer deposition (ALD) of Ni film with high growth per cycle (GPC) value is developed in this study using an electron-rich compound (N,N,N',N'-tetramethylethylenediamine) (bis(2,4-pentanedionato)) nickel(ii) and anhydrous hydrazine as the reactants. The thermal properties and adsorption behavior of selected compounds were studied. Significantly, a high film GPC value of 2.1 Å per cycle for ALD was achieved, and the deposited film exhibited high purity, low resistivity and a smooth surface. We believe that such an efficient method for high GPC thermal ALD of Ni and even other transition metals will benefit ALD technology development.

Proliferating animal cells maintain a stable size distribution over generations despite fluctuations in cell growth and division size. Previously, we showed that cell size control involves both cell size checkpoints, which delay cell cycle progression in small cells, and size-dependent regulation of mass accumulation rates (Ginzberg et al., 2018).

Anisotropic carrier transport and deep-level defect of antimony selenosulfide (Sb(S,Se)) absorber are two vital auses restraining the photovoltaic performance of this emerging thin-film solar cell. Herein, chelate engineering is proposed to prepare high-quality Sb(S,Se) film based on hydrothermal deposition approach, which realizes desirable carrier transport and passivated defects by using tetrahedral PO ion in dibasic sodium phosphate (NaHPO, DSP). The PO Lewis structure, on one hand in the form of [(SbO)(PO)] chelate, can adsorb on the polar planes of cadmium sulfide (CdS) layer, promoting the heterogeneous nucleation, and on the other hand, the tetrahedral PO inhibits horizontal growth of (SbS(e)) ribbons due to size effects, thus achieving desirable [hk1] orientation.

Bilayer graphene ribbons (GRs) hold great promise for the fabrication of next-generation nanodevices, thanks to unparalleled electronic properties, especially the tunable bandgap in association with twist angle, ribbon width, edge structure, and interlayer coupling. A common challenge in manufacturing bilayer GRs via templated chemical vapor deposition (CVD) approach is uncontrollable dewetting of micro- and nano-scaled patterned metal substrates. Herein, a confined CVD synthetic strategy of bilayer GR arrays is proposed, by utilizing the bifunctional Ni as a buffered adhesion layer to regulate the anisotropic dewetting of metal film in the V-groove and as a carbon-dissolution regulated metal to initiate the bilayer nucleation.

Oral squamous cell carcinoma (OSCC) is a type of head and neck cancer (HNC) with a high recurrence rate, which has been reported to be associated with the presence of cancer stem cells (CSCs). Tribbles pseudokinase 3 (TRIB3) is involved in intracellular signaling and the aim of the present study was to investigate the role of TRIB3 in the maintenance of CSCs. Analysis of The Cancer Genome Atlas database samples demonstrated a positive correlation between TRIB3 expression levels and shorter overall survival rates in patients with HNC.

Pancreatic cancer is an aggressive tumor, which is often associated with a poor clinical prognosis and resistance to conventional chemotherapy. Therefore, there is a need to identify new therapeutic markers for pancreatic cancer. Although KIN17 is a highly expressed DNA‑ and RNA‑binding protein in a number of types of human cancer, its role in pancreatic cancer development, especially in relation to progression, is currently unknown.
