Synthesis, Crystal Structure, Fluorescence and Theoretical Calculations of Three Zn(II)/Cd(II) Complexes with Bis-dentate N,N-Quinoline Schiff Base.

Three d metal complexes, ZnL(OAc) (1), CdL(OAc) (2) and [CdL(NO)]·CHCN (3) were synthesized using the ligand (E)-N-(3-methoxy-4-methylphenyl)-1-(quinolin-2-yl)methanimine (L) and characterized by FT-IR spectra, NMR spectra, and CHN elemental analysis. Single-crystal X-ray diffraction analysis revealed that complexes 1 and 2 are isostructural, with the central metal adopting a hexacoordinate octahedral geometry, while complex 3 adopts a triangular dodecahedron geometry. Thermal gravimetric analysis showed that these complexes exhibit good thermal stability.

Diversity of Culturable Bacteria from the Coral Reef Areas in the South China Sea and Their Agar-Degrading Abilities.

The South China Sea (SCS) is abundant in marine microbial resources with high primary productivity, which is crucial for sustaining the coral reef ecosystem and the carbon cycle. Currently, research on the diversity of culturable bacteria in the SCS is relatively extensive, yet the culturable bacteria in coral reefs has been poorly understood. In this study, we analyzed the bacterial community structure of seawater samples among Daya Bay (Fujian Province), Qionghai (Hainan Province), Xisha Islands, and the southern South China Sea based on culturable methods and detected their abilities for agar degradation.

Facile aqueous synthesis and comparative evaluation of TiO-semiconductor and TiO-metal nanohybrid photocatalysts in antibiotics degradation under visible light.

Advanced oxidation processes using TiO-based nanomaterials are sustainable technologies that hold great promise for the degradation of many types of pollutants including pharmaceutical residues. A wide variety of heterostructures coupling TiO with visible-light active nanomaterials have been explored to shift its photocatalytic properties to harness sun irradiation but a systematic comparison between them is lacking in the current literature. Furthermore, the high number of proposed nanostructures with different size, morphology, and surface area, and the often complex synthesis processes hamper the transition of these materials into commercial and effective solutions for environmental remediation.

Semirigid Highly Conjugated Zirconium-Organic Framework for the Capture of Micropollutants and Solar-Light Photodegradation.

Micro-organic pollutants, particularly organic dyes and personal care products (PPCPs), are widely present in wastewater, and thus pose a serious risk to human health. The capture and solar-light photodegradation of micro-organic pollutants are highly challenging tasks, which require the design and synthesis of microporous materials with specific structures. As we know, organic dyes and PPCPs can be absorbed via π-π* stacking.

The Harvest of a Lateral Segment of Costal Cartilage for Treating Nasal Deformities.

Background: Although costal cartilage has many uses and is a reliable source of cartilage for rhinoplasty procedures, donor-site complications may arise with conventional harvesting techniques. The present report reports a novel technique of harvesting costal cartilage using a specially designed scalpel and studies the use of the harvested cartilage in the reconstruction of secondary nasal deformities in patients with cleft lips.

Methods: Ten patients (7 females and 3 males) with nasal deformities secondary to cleft lip underwent rhinoplasty using this new technique at the Department of Oral and Maxillofacial Surgery, Second Hospital of Hebei Medical University, China, between May 2011 and December 2013.

Synthesis and Properties of 2D Carbon-Graphdiyne.

Graphdiyne (GDY) is a flat material comprising sp- and sp-hybridized carbon atoms with high degrees of π conjugation that features uniformly distributed pores. It is interesting not only from a structural point of view but also from the perspective of its electronic, chemical, mechanical, and magnetic properties. We have developed an in situ homocoupling reaction of hexaethynylbenzene on Cu foil for the fabrication of large-area ordered films of graphdiyne.

A method for controlling the synthesis of stable twisted two-dimensional conjugated molecules.

Thermodynamic stabilization (π-electron delocalization through effective conjugation) and kinetic stabilization (blocking the most-reactive sites) are important considerations when designing stable polycyclic aromatic hydrocarbons displaying tunable optoelectronic properties. Here, we demonstrate an efficient method for preparing a series of stable two-dimensional (2D) twisted dibenzoterrylene-acenes. We investigated their electronic structures and geometries in the ground state through various experiments assisted by calculations using density functional theory.

An alternative to the classical α-arylation: the transfer of an intact 2-iodoaryl from ArI(O₂CCF₃)₂.

The α-arylation of carbonyl compounds is generally accomplished under basic conditions, both under metal catalysis and via aryl transfer from the diaryl λ(3)-iodanes. Here, we describe an alternative metal-free α-arylation using ArI(O2CCF3)2 as the source of a 2-iodoaryl group. The reaction is applicable to activated ketones, such as α-cyanoketones, and works with substituted aryliodanes.

β-Carotene as a membrane antioxidant probed by cholesterol-anchored daidzein.

β-Carotene is found to be more effective as an antioxidant in phosphatidylcholine (PC) liposomes when protecting against hydrophilic radicals compared to lipophilic radicals, as measured by the rate of formation of conjugated dienes. Daidzein alone is without effect, but decreases the antioxidative effect of β-carotene for hydrophilic initiation and increases the effect for lipophilic initiation. The newly synthesized 7-cholesterylglycol daidzein has the opposite effect for β-carotene as antioxidant, with a strong enhancement for hydrophilic initiation and a slight decrease for lipophilic initiation.

The human lung cancer drug resistance-related gene BC006151 regulates chemosensitivity in H446/CDDP cells.

This study aimed to investigate the mechanism by which the human lung cancer drug resistance-related gene BC006151 regulates chemosensitivity by down-regulating BC006151 expression via antisense gene transfer in H446/(C)DDP cells. A retroviral vector containing the antisense BC006151 sequence was constructed and transfected into H446/(C)DDP cells. Transfection of the empty vector served as a negative control.

Bone healing process around distraction implants following alveolar distraction osteogenesis: a preliminary experimental study in dogs.

In this study, a new type of distraction implant (DI) that could be transformed into a prosthetic implant after distraction was applied to augment the alveolar ridge, and the bone response around it was observed in six dogs. Two DIs were placed into the lateral edentulous submandibular ridge after osteotomy. The DIs were left to integrate into the bone after 8 days of distraction at a rate of 1 mm per day.
