Corrosion behavior of FeCrNi medium-entropy alloy fabricated by laser powder bed fusion Mater. Today Commun. (IF 3.8) Pub Date : 2024-03-07 Ao Fu, Yuankui Cao, Zhengyan Zhou, Jian Wang, Khashayar Khanlari, Bingfeng Wang, Bin Liu
The corrosion behavior of the FeCrNi medium-entropy alloy (MEA), additively manufactured using laser powder bed fusion (LPBF), were investigated in this research. Compared with the LPBF 316 L stainless steel (SS), the LPBF FeCrNi MEA shows a superior corrosion resistance in the 3.5 wt% NaCl solution. The CrO-rich passive film formed on the LPBF FeCrNi MEA has fewer defects, better self-repairing ability

Modification of magnetic mesoporous silica nanoparticles with antimicrobial peptide as recyclable and durable antibacterial agents Mater. Today Commun. (IF 3.8) Pub Date : 2024-03-07 Guanwu Yin, Xiaofan Chen, Quanbo Xu, Xiaoyue Yang, Pengfei Zhang, Haiyan Wang
Antimicrobial peptides (AMPs) play a significant role in combating antimicrobial resistance. However, the applications of AMPs are constricted by insufficient stability under physiological conditions. Therefore, developing novel and effective antibacterial materials with AMPs is an urgent demand. In this study, magnetic mesoporous silica nanoparticles were fabricated through a facile method and stable

Green vanillin coupled with P/N/Si flame retardant for poly (L-lactic acid) Mater. Today Commun. (IF 3.8) Pub Date : 2024-03-06 Huidi Xu, Xiaofeng Song, Dongsheng Chen, Juanfen Chen, Yanhe Wang, Jianguo Shi, Jie Yang, Lei Liu
To better solve the flammability of poly (l-lactic acid) (PLLA) and meet environmental concerns, developing bio-derived flame retardants for PLLA is an alternative method. A green flame retardant (VKD) was synthesized in the work. Vanillin was modified using 3-amino-propyl-triethoxysilane (KH550) prior to coupling with 9, 10-dihydro-9-oxa-10-phosphafi-10-oxide (DOPO). As the blend ratio of VKD to PLLA

Characterization of the effect of fractal micro-protrusion and heat on the wettability behavior on chips in medical MEMS Mater. Today Commun. (IF 3.8) Pub Date : 2024-03-06 Rong Li, Ziyue Wang, Lihua He, Ban Wang, Haoyu Mao, Meiling Yu
Interfacial wettability, a fundamental property of solid surfaces in the medical field, is known to be affected by surface microstructure and temperature. This research aims to examine the influence of temperature on wettability by creating two distinct types of fractal single-stage microstructures on medical silicon wafers, utilizing the combined features of single-stage microstructure and fractal

Superconductivity in transition metal carbides, TaC and HfC: A density functional theory study with local, semilocal, and nonlocal exchange–correlation functionals Mater. Today Commun. (IF 3.8) Pub Date : 2024-03-06 Muhammad Azam, Muhammad Shahbaz, Habeeb-ur-Rehman, Numan Khan
We studied electronic, dynamical, and superconducting properties of TaC and HfC using local, semilocal, and nonlocal exchange–correlation functionals in the density functional theory. It turns out that there is a slight shift of Fermi energy and the corresponding density of states with different functionals. However, the phonon frequencies of, especially, the optical modes for both TaC and HfC shift

Hot processing performance and fracture toughness control of AlxCrFeNiCu1.5 (x = 0, 0.2, 0.4, 0.6, 0.8) high entropy alloys Mater. Today Commun. (IF 3.8) Pub Date : 2024-03-06 Shulin Dong, Rongyi Na, Yingdong Qu, Ruirun Chen, Guanglong Li, Wei Zhang, Siruo Zhang, Shibing Liu
In order to develop high-entropy alloys with both good hot processing performance and fracture toughness, AlCrFeNiCu(=0, 0.2, 0.4, 0.6, 0.8) alloys were designed and prepared. The alloy was firstly hot rolled by a twin-roll rolling device, and then the hot processing performance of the alloy under different Al contents was explored, whether the fracture toughness was at an ideal level, and if so, why

Efficient delivery of fucoxanthin using alginate oligosaccharide-coated mesoporous silica Mater. Today Commun. (IF 3.8) Pub Date : 2024-03-06 Wei Zhao, Siying Huang, Minlan Li, Xiao–kun Ouyang, Junhong Ling
Fucoxanthin (FX) is a hydrophobic drug with potential antitumor activity. The main challenge with using fucoxanthin as a therapeutic agent is its low bioavailability and poor physicochemical stability. To overcome these limitations, we designed a pH-targeted delivery system using alginate oligosaccharide-encapsulated aminated mesoporous silica (nMSN-FX-ALG). The drug release experiments indicated that
