title: Nicotinamide N-methyltransferase bisubstrate inhibitor
title: Nicotinamide N-methyltransferase bisubstrate inhibitor

description: Nicotinamide N-methyltransferase (NNMT) catalyzes the transfer of a methyl group from S-adenosylmethionine (SAM) to nicotinamide (NAM) and other pyridine-related compounds and is involved in various metabolic processes in the human body. In addition, abnormal expression of NNMT occurs under various pathological conditions such as cancer, diabetes, metabolic disorders, and neurodegenerative diseases, making it a promising drug target worthy of in-depth research. Small-molecule NNMT inhibitors with high potency and selectivity are necessary chemical tools to test biological hypotheses and potential therapies. In this study, we developed a series of highly active NNMT inhibitors by modifying N7 position of adenine. Among them, compound 3-12 (IC50 = 44.9 nM) exhibited potent inhibitory activity and also had an excellent selectivity profile over a panel of human methyltransferases. We showed that the N7 position of adenine in the NNMT bisubstrate inhibitor was a modifiable site, thus offering insights into the development of NNMT inhibitors.

title: High Repetition Rate Three-wavelength Laser for Particulate Organic Carbon Detection
title: 用于海洋颗粒有机碳探测的高重频三波长激光器

description: Particulate Organic Carbon (POC) is an important form of carbon in the ocean. A multi-wave laser source for POC hyperspectral detection LiDAR with high repetition rate and high beam quality was developed, using frequency stabilized seed source combined with fiber-bulk hybrid amplification technology and nonlinear frequency conversion technology. A 1064 nm single-frequency distributed feedback (DFB) semiconductor laser was used as the seeder, and an iodine molecular absorption pool was designed to control the frequency stability. The seeder laser was chopped into nanosecond pulse train with a repetition rate of 5 kHz by an acousto-optic modulator after continuous fiber amplifier, and then amplified by a fiber-bulk hybrid cascaded amplifier. Finally, more than 2.6 mJ of 355 nm ultraviolet (UV) laser pulse energy was achieved by third harmonic generation through two LBO crystals, with conversion efficiency of about 42%. Pumped by 355 nm laser pulse, 486.1 nm blue laser pulse was obtained from an optical parametric oscillator system (OPO) based on BBO crystal, the maximum output pulse energy of 0.7 mJ was achieved with pulse width of 6.9 ns, corresponding to an optical-optical conversion efficiency of 26.9%.

title: Effect of filler metal on microstructure and mechanical properties of welded SiCp/Al composites by dual beam laser welding
title: 填充金属对双光束激光焊接SiCp/Al复合材料显微组织和力学性能的影响

description: In this study, the microstructure and mechanical properties of SiCp/6005Al composite welded joints with three different filler metals were studied by dual beam laser welding method. The tensile strength of SiCp/Al composite welded joints with Al-Si welding wire (ER4043 and ER4047) is higher than that with Al-Mg welding wire (ER5356). The main reason for the difference of tensile strength of weld joints is that the brittle phase Al4C3 is formed by the interfacial reaction between SiC particles and Al matrix at high temperature. More Si content in ER4047 can effectively inhibit the interface reaction and reduces the consumption degree of SiC particles in the welded metal, therefore a large number of SiC particles are retained to improve performance of weld seam compared with the other two welding wires.
