Hydrolysis of waste office paper (WOP) into fermentable sugars is an important option of WOP utilization. In this work, the effect of major chemicals in WOP on its hydrolysis using industrial cellulase Accellerase 1000 (Genencor,Rochester, NY, USA) was investigated, and calcium carbonate (CaCO_3) was found to be the key parameter affecting the enzymatic hydrolysis efficiency of WOP. The pretreatment methods, acid washing and acid presoaking, were tested for the removal of CaCO_3 from WOP. It was found that the presoaking of sulfuric acid (H_2SO_4) in WOP was an effective way. The pretreating parameters of WOP were studied on maximizing the hydrolysis efficiency. The conversion yield of cellulose to glucose and cellobiose using the pretreated WOP reached 73.3% after 96 hours hydrolysis at the optimal conditions. The results provided the WOP utilization with a practical enzymatic hydrolysis method with industrial application potential.

As a part of R&D work for the high intensity proton linac of China Accelerator Driven Sub-critical System project, a superconducting half-wave cavity with a frequency of 162.5 MHz and an optimal beta of 0.15 (HWR015) has been developed at Institute of Modern Physics (IMP), Chinese Academy of Sciences. In this paper, the design and test results will be described in detail. We introduced a new stiffening strategy for the HWR cavity, the simulation results show that the cavity has much lower frequency sensitivity coefficient (df/dp), Lorentz force detuning coefficient (KL), and can achieve more stable mechanical properties. The performance of the HWR cavity operated in cryostat will be also reported.

Solving the reachable workspaces of spatial hyper-redundant manipulators (SHRMs) formed by serially connected parallel manipulators is an important and challenging work. This study addresses the issue on reachable workspaces and establishes a novel CAD-VBbased workspace determination system for determining the reachable workspaces of SHRMs. The reachable workspace determination of a novel (3-RPS)+(3-SPR)+(3-RPS) SHRM, a triple delta-type SHRM, and a novel (3-RRS)+(3-SPR)+(3-RRS) SHRM shows the generality and effectiveness of the proposed approach. The system proposed in this study can contribute to reachable workspace analysis for SHRMs.
