Mosses form a diverse land plant group in modern vegetation but have rarely showed up in the fossil record compared with vascular plants. Here, we report an extraordinarily-preserved early Miocene moss fossil from the lower Laoliangdi Formation in the Pingzhuang Coal Mine in Chifeng, Inner Mongolia Autonomous Region, northern China. Although lacking rhizoids and most reproductive organs, the well-preserved fossil allows us to assign it to Platydictya cf. jungermannioides (Amblystegiaceae) based upon its detailed gross and micro-morphology. The diagnostic characteristics include a small-sized body with slender stems bearing spirally arranged ovate-lanceolate leaves that lack costae. Leaf margins are mostly partly entire and partly dentate, a few dentate, and rarely completely entire. It represents the first fossil record of Platydictya in Asia. The specific living microenvironment of the extant P. jungermannioides enriched our understanding of the early Miocene environment that was previously based upon vascular plant fossils and sedimentary lithofacies in the area. Our early Miocene Platydictya cf. jungermannioides fossil lived in a warm and humid lush forest with a dense understory that received adequate water supplies.

Biochar is a functional and environmentally friendly material mainly made from by-products of industrial and agricultural production as raw material, which is cracked at high temperatures and slow speeds. The preparation of biochar requires the thermochemical conversion of biomass in an oxygen-restricted environment. Different raw materials and preparation processes result in biochar with different internal structures and biofunctional groups, which often have different properties. Adsorption of heavy metal pollutants is one of the main research directions for biochar application, and there are still areas that can be improved in the current research for biochar for treating heavy metal wastewater. In this study, we take the treatment of cadmium-containing wastewater as an example, walnut shell biochar (WSBC) as a carrier, iron(VI) compounds as a modifying reagent, and test the performance of cadmium-containing wastewater treatment using simulated cadmium-containing wastewater by adjusting the pyrolysis process and modification method at the same time to find the optimal experimental scheme, and give a reasonable theoretical explanation in relation to the results of the characterization tests, such as SEM, FT-IR, and so on. The characterized results show that iron(VI) compound (K2FeO4)-modified WSBC has a significant ability to remove cadmium contamination in the wastewater (remove 96.62% of cadmium in 1 minute), and its structure is different from other iron compound-modified ones. The aim of this study is to improve the efficiency of cadmium adsorption by specific types of biochar, while realizing the whole process as environmentally friendly as possible.

Sodium gluconate(SG)is reported as an electrolyte additive for rechargeable aqueous zinc *** SG addition is proposed to modulate the nucleation overpotential and plating behaviors of Zn by forming a shielding buffer layer because of the adsorption priority and large steric hindrance effect,which contributes to limited rampant Zn^(2+)diffusion and mitigated hydrogen evolution and *** the introduction of 30 mmol/L SG in 2 mol/L ZnSO_(4)electrolyte,the Zn anode harvests a reversible cycling of 1200 h at 5 mA/cm^(2)and a high average Coulombic efficiency of Zn plating/stripping(99.6%).Full cells coupling Zn anode with V_(2)O_(5)·1.6H_(2)O or polyaniline cathode far surpass the SG additivefree batteries in terms of cycle stability and rate *** work provides an inspiration for design of a high-effective and low-cost electrolyte additive towards Zn-based energy storage devices.

Situated in the geographical geometry center of China, Shaanxi has played an important role in gathering and radiating regional economy with its regional advantage as the center of the mainland since ancient times. Especially in the history of Silk Road, as then political and economic center of China, Shaanxi brought in commodities from various countries. Meanwhile, China＇s silk, porcelain, tea and other products which attracted countries along the Silk Road most were shipped from here to various countries along the Silk Road, which has laid the foundation of Shaanxi as the trade and logistics center of Silk Road.
