Six new metal-organic frameworks based on 2,5-thiophendicarboxylate (tdc2–) and zinc(II) ions were prepared in different reaction conditions, and their crystal structures were determined by XRD analysis. The compound [Zn(tdc)(dabco)(H2O)]·DMF (1) is based on mononuclear Zn(II) ions connected by tdc2– and dabco linkers into square-grid layered nets. The compound [Zn3(tdc)3(dabco)2] (2) is a rare...

The crystallographic signatures and characterization data of two novel organically templated open-framework zinc-sulfites (NH3CH2CH2NH3)[Zn3(SO3)4], 1, and (CN3H6)2[Zn(SO3)2], 2, are reported for the first time, synthesized under hydrothermal conditions using different amines, namely, ethylenediamine and guanidine, to generate 2D (for 1) and 3D (for 2) assemblies with 4-, 6-, 8- and 12-membered...

Mục tiêu: Mô tả biến đổi nồng độ kẽm (Zn) huyết tương và tìm hiểu mối liên quan giữa Zn với bệnh cảnh lâm sàng ở nhân (BN) nhiễm khuẩn (NKH). Đối tượng phương pháp: Nghiên cứu tiến mô được hành trên 125 BN NKH điều trị tại Bệnh viện TWQĐ 108 từ tháng 11/2019 đến 02/2021. Đo thời điểm vào (Zn1) ngày 3 (Zn3) sau viện, ghi nhận sống sót tử vong (TV) 30 ngày. Kết quả: Tỷ lệ thiếu Zn1 là 72,8%. Nồng...

In this work, the photocatalytic activity of Zn3(PO4)2 was effectively enhanced based on Zn3(PO4)2/ZnO composites. Hence, properties were investigated using various ratios in ZnO and dissimilar approaches for synthesis (co-precipitation solid-state reaction). The physicochemical morphological composition as-prepared catalysts characterized by XRD, SEM, EDS FTIR techniques. Furthermore, activiti...

We report here a luminescent metal-organic framework [Zn3(TDPAT)(H2O)3] [TDPAT = 2,4,6-tris(3,5-dicarboxyl phenylamino)-1,3,5-triazine] exhibiting strong luminescence at room temperature, which can serve as the first case of a dual functional luminescent sensor for quantitatively detecting the concentration of nitrobenzene and temperature.

Plant associated rhizobacteria prevailing in different agro-ecosystems exhibit multiple traits which could be utilized in various aspect of sustainable agriculture. Two hundred thirty four isolates were obtained from the roots of basmati-385 and basmati super rice varieties growing in clay loam and saline soil at different locations of Punjab (Pakistan). Out of 234 isolates, 27 were able to sol...

Chemical transformations of silver nanoparticles (Ag NPs) and zinc oxide nanoparticles (ZnO NPs) during wastewater treatment and sludge treatment must be characterized to accurately assess the risks that these nanomaterials pose from land application of biosolids. Here, X-ray absorption spectroscopy (XAS) and supporting characterization methods are used to determine the chemical speciation of A...

Step 2 Phosphating The metal is treated with phosphoric acid, leading to the following two reactions occuring in the zinc-rich surface of the steel: 2H3PO4 + 3Zn → 3H2 + Zn3(PO4)2 2H3PO4 + Fe + 2Zn → 3H2 + FeZn2(PO4)2 This gives a mixture of zinc phosphates. The electrocoat paint binds better to these zinc phosphates than to the steel alone, and the zinc phosphates corrode much slower than the ...
