One potential way to fabricate battery-on-chip is photopatterning electrochemical energy storage materials directly on electronics through lithography, but applicable materials are primarily limited to transparent photocurable resins. The transparency of the photoresist would be sacrificed after extra addition of insoluble inorganic battery materials and conductors. Given the importance of radical polymers for their appropriate solubility, optical transparency, and radical robustness, they may have potential application in on-chip energy storage, transport, and conversion devices. Herein, an anodic photoresist is proposed by modifying the MicroChem SU8 resist with a radical polymer poly(2,2,6,6-tetramethyl-4-piperidinyl-N-oxyl methacrylate) and an ionic conductor lithium perchlorate. It can be photopatterned on silicon wafer with 10 μm scale resolution, and it exhibits charge/discharge potentials at ca. 0.68 V versus silver chloride electrode; the coulomb efficiency is regarded as nearly equaling 100%. Although the specific capacity of the photopatterned film electrode is found to be modest, 1 × 10–5mA h·cm–2, it presents 1/8 of its theoretical electron storage ability. All-solid-state half-cells with circular features 30 μm in diameter are prepared by means of overlay exposure using the as-prepared photoresist and lithium perchlorate-modified SU8 as the anodic electrode and solid electrolyte, respectively. These results suggest a promising way of using radical polymers for the integration of electrochemical energy in microelectronics.

Based on the study of self-Q-switching of a short cavity erbium-doped distributed Bragg reflector (DBR) fiber laser in time domain, the influence of pressure disturbance on the self-Q-switched output is analyzed. In the experiment, the erbium-doped DBR fiber laser (EDFL) was encapsulated with epoxy resin and curing agent to protect and sensitize the fiber. The EDFL sends out self-Q-switched laser pulses when the pump power of the 980 nm laser source is more than 110 mW. The external pressure is exerted on the DBR fiber and increased gradually from 0 g (0 N) to 120 g (1.176 N) in 10 g unit with the pump power fixed at 360 mW, and the following approximately linear changes of self-Q-switched laser pulses outputs are observed by the oscilloscope: the peak voltage of output pulses reduces from 12.59 mV to 1.883 mV; the pulse repetition rate reduces from 125.0 kHz to 66.67 kHz; and the pulse width increases from 0.4083 μs to 1.28 μs.

Abstract: Objective: To observe the clinical effect of Shengxueling (SXL) on idiopathic thrombocytopenic purpura (ITP), and study the possible mechanism.Methods: Eighty-six cases of ITP were randomly divided into two groups. The SXL group, 56 patients treated with SXL, a traditinal Chinese medicine and 30 patients administered with prednisone were taken as control. Each group took drugs for 3 months and was under follow-up observation.Results: In the SXL group, the total effective rate was 85. 71%, similar to prednisone 83. 33%(P>0. 05) for 3 months, but the total effective rate of SXL (91.07%) were obviously better than that of the control group (53. 33%) (P<0.01) for 6 months and had no obvious adverse reaction. The patients bleeding was alleviated or stopped, the general condition was improved. At the same time, blood platelet count (PLT) was increased, platelet associated immunoglobulin (PAIg) and interleukin-4 (IL-4) were markedly dropped, the level of natural killers cells activity (NKa) increased, the rate of T lymphocyte subsets gradually returned to normal level. Megakaryocyte tended to maturation on bone marrow smear after treatment. All differences above were statistically significant.Conclusion: SXL is an effective and safe medicine for ITP. Its mechanism could regulate cytoimmune, inhibit platelet antibody to reduce the destruction of platelet, increase the number of platelet, promote the division and maturation of megakaryocyte, facilitate the production and release of platelet, lower the fragility of capillary, prevent and cure hemorrhagic tendency.
