Dye sensitized solar cells（DSSCs） have attracted much attention over conventional semiconductor solar cells, because of their cost advantages. [1, 2] In a representative device, charge carriers are generated by monolayers of dye molecules upon solar energy absorption, subsequently injected into semiconductor photoanode, and then diffuse across the interconnecting TiO2 nanoparticles and finally are collected by the transparent conductor F doped SnO2（FTO）.1-2 Here, TiO2 nanocrystallites with titanium（IV） fluoride treatment were fabricated and studied as dye sensitized solar cells photoanode. F doping into pre-existing mesoporous TiO2 is achieved by a simple hydrolysis method. Overall photo-to-current conversion-efficiency of the device could be enhanced up to 23% due to the increase of photocurrent density, fill factor and open-circuit voltage, compared with undoped TiO2. From electrochemical impedance measurements, we deduce that the presence of F dopants enhances cell performance by improving the charge transport and retarding the recombination process in the photoanode（Fig.1）.

In the past few years, organic-inorganic hybrid trihalide perovskite CH3NH3 Pb I3 has drawn much attention of many researchers due to their attractive properties for solar cells, lasing, Light-emitting diodes. Here, the perovskite-type organic-inorganic tin compound,（c-His His）Sn I3, has been hydrothermally synthesized and characterized by elemental analysis, FT-IR spectra, thermogravimetric analysis（TGA） and single-crystal X-ray diffraction. Histidine condensed into dipeptide via hydrothermal in situ reaction, forming increasingly more stable tin complexation of cyclic dipeptides（see Figure1）. Our single-crystal X-ray studies indicate that its cell parameters at room temperature : a = 11.7539（5） ?, b = 11.8400（5） ?, c = 11.8655（4） ?, α = 60.852（2）°, β = 87.114（2）°, γ = 69.271（2）°, V = 1333.67（9） ?3, Z = 12. The successful preparation of this complexation not only enriches the catalogue of c-His His coordination polymers but also provides a valuable approach for the construction of other dipeptides coordination polymers.

Based on mobile devices as a solution for measurement faces interesting challenges, which involve poor human- computer interaction and limited computer capability. In this paper, we present the mobile sensing system （MSS） with func- tions of constructing, configuring and implementing measurement applications. MSS consists of a mobile device and a sensor probe, In the mobile device we install a pocket virtual instrument platform （PVIP）, which has object-oriented software ar- chitecture and can be configured through extensible markup language （XML） files. And these configuration files can be written to the probe. Therefore, the probe can produce the measurement of APP in the mobile device. This infrastructure has been illustrated by a sound signal acquisition task and a flexible force measurement task which are finished with an android smartphone and a probe. These examples suggest that MSS is reconfigurable, highly automatical and flexible.

MoS2 nanodots are emerging as promising semiconductor materials for optoelectronic devices. However, most of the recent attention is focused on the fabrication of MoS2 nanodots,and the survey for exciton dynamics of MoS2 nanodots remains less explored. Herein, we use femtosecond transient absorption spectroscopy to investigate the carrier dynamics of MoS2 nanodots. Our results show that defect-assisted carrier recombination processes are well consistent with the observed dynamics. The photo-excited carriers are captured by defects with at least two different capture rates via Auger scattering. Four processes are deemed to take part in the carrier relaxation. After photoexcitation, carrier cooling occurs instantly within ～0.5 ps. Then most of carriers are fast captured by the defects, and the corresponding time constant increases from ～4.9 ps to ～9.2 ps with increasing pump fluence, which may be interpreted by saturation of the defect states. Next a small quantity of carriers is captured by the other kinds of defects with a relatively slow carrier capture time within ～65 ***, the remaining small fraction of carriers relaxes via direct interband electron-hole recombination within～1 ns. Our results may lead to deep insight into the fundamentals of carrier dynamics in MoS2 nanodots, paving the way for their further applications.

Why do humans punish free riders at their own expense? This behavior represents an evolutionary puzzle in human societies. This study explores the role of exit strategies in fostering altruistic punishment within evolutionary game theory. We extend the traditional prisoner's dilemma model by incorporating exiters, players who opt out for a small payoff while nullifying their opponent's payoff, and altruistic punishers who cooperate and punish non-cooperators. Our findings indicate that in well-mixed populations, exiters destabilize defection but do not promote altruistic punishment. In social networks, however,exiters enable altruistic punishment via cyclic dominance among altruistic punishers, defectors, and exiters. Notably, this cyclic dominance is sensitive to exit payoffs; adjustments can lead to cyclic dominance of non-punishing cooperators, defectors, and exiters, or to a bi-stable state between these two types of cyclic dominance. These results highlight the nuanced impact of exiters on altruistic punishment, emphasizing the need for careful incentivization of exit behavior. While exiters can support altruistic punishment in networked populations, their effectiveness is not a panacea and is highly sensitive to exit payoffs, indicating limits to the voluntary participation mechanism.
