为提高纤维高强混凝土(FHPC)的性能,探究了硅灰、I级粉煤灰和S95矿渣粉在不同掺量和掺加方式下对FHPC力学性能及尺寸效应的影响。结果表明单掺矿物掺料中,S95矿渣粉对提高FHPC抗压强度和抗折强度效果最好,硅灰次之,I级粉煤灰效果最弱。当I级粉煤灰与S95矿渣粉以1:2复掺时,FHPC的抗压强度显著提高;硅灰与S95矿渣粉以1:1复掺时,FHPC的抗折强度提升效果最好。同时加入3种掺合料,保持硅灰掺量不变的情况下,I级粉煤灰与S95矿渣粉以1:1复掺,可以显著提高FHPC的力学性能。此外,低水胶比下FHPC的抗压抗折强度尺寸效应更为显著,但随着水胶比的增加,FHPC的抗压抗折强度尺寸效应逐渐减弱。

Laser solid forming (LSF) is an advanced manufacture technology developed from early 1990s, which can realize the rapid manufacturing high performance near-net-shaping complicated metallic components with full-dense directly. Currently this technology has been widely used for rapid manufacturing of metal parts, repairing and remanufacturing service of large parts with defects in aerospace, energy, transportation industry etc. In present paper, the main progresses on the research and application of LSF are reviewed, and the emphasis has been focused on manufacturing high performance high strength steel metal parts. The results of LSFed high strength steel samples show that the comprehensive mechanical properties are usually in the classes of forging parts, which the dense, fine and homogeneous microstructure in LSFed parts, especially, high strength steel parts with metallurgical-defects-free can be obtained by careful optimizing the forming and heat treatment parameter. To realize the high performance repairing and remanufacturing of the high strength steel component is one of the most remarkable progress for LSF recently. The mechanical properties of the repaired and remanufacturing parts by LSF can reach the wrought standards only with annealing treatment. It is believed that the repair and remanufacturing of high performance metallic components by LSF should be one of the most promising applications for LSF in the coming future.

为制作橄榄高纤维曲奇饼干,将橄榄果渣添加至曲奇饼干中。首先考察5%~10%的橄榄果渣添加量对曲奇饼干的感官和理化品质的影响。在确定橄榄果渣的最佳添加量后,设置单因素实验,考察120、125、130℃和135℃的烘焙温度及20、25、30、35 min和40 min的烘焙时间对橄榄曲奇感官和理化品质的影响。结果显示,当果渣添加量为6%时,曲奇饼干质构结果最为理想,且感官评分最高,达到83.4分。曲奇饼干的品质随烘焙温度升高和时间延长均呈现先上升后下降的趋势。综合发现在130℃温度下烘烤25 min的曲奇饼干质构结果最理想,且感官评定分数最高。富含膳食纤维的橄榄果渣可以作为食品加工的重要原料,从而提高橄榄果渣的利用率和经济效益。

In response to the ongoing energy crisis, advancing the field of electrocatalytic water splitting is of utmost significance, necessitating the urgent development of high-performance, cost-effective, and durable hydrogen evolution reaction catalysts. But the generated gas bubble adherence to the electrode surface and sluggish separation contribute to significant energy loss, primarily due to the insufficient exposure of active sites, thus substantially hindering electrochemical performance. Here, we successfully developed a superaerophobic catalytic electrode by loading phosphorus-doped nickel metal （NiPx） onto various conductive substrates via an electrodeposition method. The electrode exhibits a unique surface structure, characterized by prominent surface fissures, which not only exposes additional active sites but also endows the electrode with superaerophobic properties. The NiPx/Ti electrode demonstrates superior electrocatalytic activity for hydrogen evolution reaction, significantly outperforming a platinum plate, displaying an overpotential of mere 216 mV to achieve a current density of-500 mA cm-2in 1 M KOH. Furthermore,the NiPx/Ti electrode manifests outstanding durability and robustness during continuous electrolysis, maintaining stability at a current density of-10 mA cm-2over a duration of 2000 h. Owing to the straightforward and scalable preparation methods, this highly efficient and stable NiPx/Ti electrocatalyst offers a novel strategy for the development of industrial water electrolysis.
