The design and manufacture of anti-scaling surface is a prospective way to prevent scaling in oil *** this work,a novel superhydrophobic Cu^(2+)-loaded and DTPMPA-modified anodized copper oxide(S-Cu^(2+)/D-ACO)coating was fabricated by modification of 1H,1H,2H,*** valid storing of scale inhibitors at the coating surface and the interfacial release of Cu^(2+)ions contribute to enhancing the anti-scaling of the S-Cu^(2+)/D-ACO *** water contact angle of the S-Cu^(2+)/D-ACO coating is 163.03°and exhibits superhydrophobicity,which makes it difficult for CaCO_(3)to deposit at the surface of the *** will steadily lurk into the inner space,and Cu^(2+)will be loaded at the interface in the form of the DTPMPA:Cu^(2+)*** the deposition of CaCO_(3),the dynamic release of DTPMPA can be realized by transferring DTPMPA:Cu^(2+)to DTPMPA:Ca^(2+).Interestingly,the released Cu^(2+)hinders the active growth of CaCO_(3).After 48 h of scaling,the mass of CaCO_(3)scale at the S-Cu^(2+)/D-ACO coating surface is only 44.1%that of the anodized copper oxide *** excellent anti-scaling performance of the S-Cu^(2+)/D-ACO coating is determined by the synergistic effect of the DTPMPA lurking and dynamic release,as well as the Cu^(2+)inhibition at the interface of superhydrophobic coating and against CaCO_(3)*** research provides a new exploration for designing and fabricating anti-scaling superhydrophobic surface for oil field development.

chinese Medical Journal 2008年第8期121卷 687-690页

作者： GUO Li-xin PAN Qi wang Xiao-xia LI Hui ZHANG Li-na chi jia-min wang Yao Department of Endocrinology Beijing Hospital Beijing 100730 China

Background Controlling plasma glucose levels, blood pressure and lipid levels is proven to reduce the risk of vascular complications in patients with type 2 diabetes mellitus. This has prompted intensive multitherapy targeted at several macrovascular risk factors. Carotid intima-media thickness （cIMT） is a reliable measure of early atherosclerosis. We sought to determine whether a 6-month intensive mutiltherapy program resulted in better goal attainment than usual care and its effect on the development of cIMT among patients with newly diagnosed type 2 diabetes mellitus. Methods The study randomly assigned 220 patients with newly diagnosed type 2 diabetes mellitus to intensive or traditional therapy groups. The clinical parameters, such as fasting plasma glucose, total cholesterol, triglyceride, blood pressure, body weight and insulin were assessed at the baseline and after the 6-month therapy, cIMT of the patients was also obtained. Results The average levels of fasting plasma glucose, hemoglobin Alc, total cholesterol （TC） and low-density lipoprotein cholesterol （LDL-C） in the intensive group were significantly lower than those in the control group at the end of 6-month treatment. By 6 months, a higher proportion of patients in the intensive therapy group than in the control group attained goals for fasting plasma glucose （FPG）, TC, LDL-C and hemoglobin Alc. With intensive multherapy the level of carotid intima-media thickness in the intensive therapy group was lower than that in the control group （（0.88±0.26） mm vs （0.96±0.22） mm, P 〈0.01）. Conclusions The evidence from this clinical trial demonstrates that intensive glucose, lipid and blood pressure control in patients with newly diagnosed type 2 diabetes is associated with diabetic macrovascular benefits. Intensive multitherapy allows more patients to achieve aims of control and may reduce macrovascular complications and delay disease progression.

Metallic nanoparticles with excellent size controllability and high loading rate are obtained via ultrafast high temperature shock *** Bi/CNRs-15 electrode exhibits an unprecedented rate performance (237.9 mAh g-1 at 2 A g-1) at - 60 degrees C, while the energy density of the full cell can reach to 181.9 Wh kg-1 at - 40 degrees C.A novel strategy of high-rate activation is proposed to obtain high capacity and superior stability at low temperature by creating new active sites for interfacial reaction. Sodium-ion batteries have emerged as competitive substitutes for low-temperature applications due to severe capacity loss and safety concerns of lithium-ion batteries at - 20 degrees C or lower. However, the key capability of ultrafast charging at ultralow temperature for SIBs is rarely reported. Herein, a hybrid of Bi nanoparticles embedded in carbon nanorods is demonstrated as an ideal material to address this issue, which is synthesized via a high temperature shock method. Such a hybrid shows an unprecedented rate performance (237.9 mAh g-1 at 2 A g-1) at - 60 degrees C, outperforming all reported SIB anode materials. Coupled with a Na3V2(PO4)3 cathode, the energy density of the full cell can reach to 181.9 Wh kg-1 at - 40 degrees C. Based on this work, a novel strategy of high-rate activation is proposed to enhance performances of Bi-based materials in cryogenic conditions by creating new active sites for interfacial reaction under large current.

Recent advances in the combined delivery platform that integrate nano-/microscale carriers and with 3D hydrogel network for bone regeneration are *** strategies for bioactive molecules delivery involving nanoparticles, nanosheets, and microspheres, along with extra stimuli such as near-infrared light, temperature changes, ultrasonication, and inflammatory conditions, are *** prospects and challenges for the clinical translation and the development of nano-/microscale incorporated hydrogel-based delivery platform are discussed. Bioactive molecules have shown great promise for effectively regulating various bone formation processes, rendering them attractive therapeutics for bone regeneration. However, the widespread application of bioactive molecules is limited by their low accumulation and short half-lives in vivo. Hydrogels have emerged as ideal carriers to address these challenges, offering the potential to prolong retention times at lesion sites, extend half-lives in vivo and mitigate side effects, avoid burst release, and promote adsorption under physiological conditions. This review systematically summarizes the recent advances in the development of bioactive molecule-loaded hydrogels for bone regeneration, encompassing applications in cranial defect repair, femoral defect repair, periodontal bone regeneration, and bone regeneration with underlying diseases. Additionally, this review discusses the current strategies aimed at improving the release profiles of bioactive molecules through stimuli-responsive delivery, carrier-assisted delivery, and sequential delivery. Finally, this review elucidates the existing challenges and future directions of hydrogel encapsulated bioactive molecules in the field of bone regeneration.
