Effect of Wavefront Properties on Numerical Aperture of Fresnel Hologram in Incoherent Holographic Microscopy

引用

Chinese Physics Letters 2014年第4期31卷 60-63页

作者： WAN yu-hong Institute of Information Photonics Technology Beijing University of Technology Beijing 100124 College of Applied Sciences Beijing University of Technology Beijing 100124

Fresnel incoherent correlation holographic （FINCH） microscopy is a recently developed new technique, which employs a spatial light modulator （SLM） as the beam splitter. Light originating from the same object point is split into two beams by the wavefront-division phase mask displayed on SLM, and a Fresnel-zone plate-like hologram is formed by the interference of the two beams. The numerical aperture NAH of the recorded Fresnel hologram is introduced as a comprehensive parameter for evaluating the imaging characteristics in the FINCH scheme. The effect of wavefront properties on NAH of the hologram is investigated theoretically in the sense of optimizing imaging resolution. The variation trends of NAH are described and an optimal NAH is achieved by implementing an appropriate phase mask for a given recording distance between SLM and CCD; thus optimized imaging resolution and signal-to-noise ratio are demonstrated experimentally.

Formation of disinfection byproducts from accumulated soluble products of oleaginous microalga after chlorination

Frontiers of Environmental Science & Engineering 2017年第6期11卷 1-7页

作者： yu Liu Qiao Zhang yu hong Beijing Key Laboratory for Source Control Technology of Water Pollution Beijing Forestry University Beijing 100083 China

When microalgae are simultaneously applied for wastewater treatment and lipid production, soluble algal products （SAP） should be paid much attention, as they are important precursors for formation of disinfection byproducts （DBPs）, which have potential risks for human health. Chlorella sp. HQ is an oleaginous microalga that can generate SAP during growth, especially in the exponential phase. This study investigated the contribution of SAP from Chlorella sp. HQ to DBP formation after *** predominant DBP precursors from SAP were identified with the 3D excitation-emission matrix fluorescence. After chlorination, a significant reduction was observed in the fluorescence intensity of five specific fluorescence regions, particularly aromatic proteins and soluble microbial by-product-like regions, accompanied with slight shifting of the peak. The produced DBPs were demonstrated to include trihalomethanes and haloacetic acids. As the algal cultivation time was extended in wastewater, the accumulated SAP strengthened the formation of DBPs. The trend for DBP formation was as follows： chloroform〉dichloroacetic acid〉trichloroacetic acid.

Chiral materials refer to species with chiral symmetry, which means the absence of mirror planes or breaking of inversion symmetry in material structures. A material or structure is chiral if it is distinguishable from its mirror images. That is, the chiral materials and their mirror images do not coincide through rotations or translations. Chiral materials are frequently described as ‘handed’ because our hands themselves are *** exists in nature, including the DNA double helix, proteins, amino acids and human hands. Interestingly, biology only adopts one chirality in nature. While DNA, RNA and their building blocks are all right-handed, amino acids and proteins are all left-handed.

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.
