Octagon (HMX) based metalized explosive containing boron (B)/aluminum(Al) compound powder, oxidizer ammonium perchlorate(AP) and binder hydroxyl-terminated polybutadiene(HTPB) was designed and prepared. The appearance morphology of B powder, Al powder and B-Al compound powder were observed by SEM. The effects of HMX a…
The simultaneous use of linear spatial encoding magnetic fields (L‐SEMs) and nonlinear spatial encoding magnetic fields (N‐SEMs) in B1+ inhomogeneity problems is formulated and demonstrated with both simulations and experiments. Independent excitation k‐space variables for N‐SEMs are formulated for the simultaneous us…
Diamond spin centers dramatically improve measurements of magnetic-field frequency
Abstract First-principles calculations have been performed to study the intrinsic spin Hall effect (SHE) and its behavior under vertical electric field in monoclinic transition metal dichalcogenide monolayers (1T′-MX 2 with M = Mo, W and X = S, Se, Te). We find that the pristine systems exhibit nonquantized intrinsic…
Two new complexes, bis(N-(2-phenylethyl)-N-(4-fluorobenzyl)dithiocarbamato-S,S′)zinc(II) (1) and bis(N-(2-phenylethyl)-N-(4-chlorobenzyl)dithiocarbamato-S,S′)zinc(II) (2), have been synthesized and characterized by various physicochemical techniques. Structure of 1 has been determined by single crystal X-ray diffracti…
ABSTRACT The current work focuses on the influence of microstructure of different lactone‐based triblock copolymers on drug delivery, where the middle segment was δ‐valerolactone or ɛ‐caprolactone and the terminal segment was d,l‐lactide or cis‐lactide. Microspheres were fabricated from the triblocks using salicylic a…
The potential toxicity of dendrimers has surfaced after nearly 3 decades of research on dendrimers. Toxicity of cationic dendrimers is still a major hurdle in their preclinical and clinical applications. It has been reported time and again that dendrimers can induce irreversible damage to organs/tissues/cells in exper…
Vegetable oil is one of the most potential alternatives of petroleum and has become a hot issue in recent years. This review focuses on the influence of vegetable oil structure on platform compounds and polymers properties, and further systematically introduces their developments and the latest progress. Meanwhile, we…
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book provides an overview of the research status of using porphyrin-phospholipids (PoP) for biomedical applications. The conjugation of porphyrins to phospholipid side chains could form PoPs, which can sel…
CSNF-RGD can improve the biomechanical property and biocompatibility of CPC, indicating its potential application in bone tissue repair.
This chapter presents a summary of the status of research into the design, development and clinical applications of nanomaterial-antibody hybrid agents. Research into the use of nanotechnology for drug delivery and imaging has witnessed remarkable growth. Targeting of diseased cells can be achieved by surface modifica…
Carbon fibre reinforced polymer (CFRP) composites employing epoxy matrices have been recently used in a number of space applications, especially in structural components of spacecraft in low Earth orbit (LEO). However, in this region, CFRP structures are subjected to degradation by highly energetic ultraviolet radiati…
以静电纺丝聚丙烯腈（PAN）纳米纤维作为多孔支撑层，以亲水材料聚乙烯醇（PVA）和海藻酸钠（SA）为亲水表层材料，通过静电喷雾技术将亲水表层材料沉积在纳米纤维多孔基膜表面，然后将表层PVA-SA纳米串珠层通过水蒸气加湿辅助热压成膜处理在PAN基膜上软化压延形成完整的致密薄膜，最后经过戊二醛交联制备PVA-SA/PAN纳米纤维基复合滤膜.通过对加湿时间、热压温度、热压时间以及PVA-SA静电喷雾时间等成膜工艺条件和交联条件进行优化制备出结构完整的PVA-SA/PAN纳米纤维基复合滤膜.所制备的复合滤膜荷负电，它对阴离子染料具有较好的过滤效果：在0.6 MPa的操作压力下对100 mg/kg的固绿染料的渗透通量为57.1 L/（m2…
Phosphate-binding proteins (PBPs) are key proteins that belong to the bacterial ABC-type phosphate transporters. PBPs are periplasmic (or membrane-anchored) proteins that capture phosphate anions from the environment and release them to the transmembrane transporter. Recent work has suggested that PBPs have evolved fo…
The ability to fabricate MgO magnetic tunnel junction nanopillars with low RA and high TMR opens the door to new devices such as magnetic memories or nanooscillators. Here, we address the dynamic behavior of a CoFeB/MgO/CoFeB MTJ with a synthetic-antiferromagnetic pinned layer as a potential candidate for spin-transfe…
Abstract Physical fabrication of chiral metallic films usually results in singular or large‐sized chirality, restricting the optical asymmetric responses to long electromagnetic wavelengths. The chiral molecule‐induced formation of silver films prepared chemically on a copper substrate through a redox reaction is pres…
The preparation of highly active electrocatalysts with good durability and low cost for fuel cells is highly desirable but still remains a significant challenge. Here we synthesized two dimensional (2D) C3N4 nanosheets supported palladium composites (C3N4/Pd) via a simple and convenient sonochemical approach. We have…
A rapid-fire electromagnetic multirail launcher design for sequential acceleration of several projectiles is proposed. A powerful pulsed MHD system is used as the primary source of electrical energy for the launcher. Embodiments of the launcher with direct powering from the MHD system and from an MHD generator with an…
A method of synthesis of single-domain nanoparticles of (Fe 1-x Ni x )Fe 2 O 4 solid solutions of oxide ferrimagnetics (where х = 0÷1) has been developed. To suppress coagulation of particles during their synthesis, we used sodium chloride as an indifferent dispersant. After washing, the precipitate was recrystallized…
Abstract The sintering behavior of green pellets obtained from nanostructured Ce 0.8 Gd 0.2 O 1.9 submillimetric microspheres is studied in the present paper. Corresponding shrinkage rate curve shows a two‐step densification in dynamic conditions, with the presence of two successive extrema, at 1200 K and 1500 K. To f…
