Advanced Science, EarlyView.The sodium hydride (NaH)‐mediated reduction of germanium dioxide yields distinct Ge structures depending on the amount of reductant, revealing the dual roles of NaH in the reduction pathways. The synthesized Ge under off‐stoichiometric conditions exhibits a porous morphology and reduced crystallinity, which effectively mitigates volume expansion during

Forecasting food prices in Central Java with the hybrid ARIMAX calendar variation model [PDF]
Songklanakarin Journal of Science and Technology (SJST)Variations in time series data that occur due to the effects of calendar factors such as holidays, seasons, or differences in the number of days in a month are referred to as calendar variations. Time series problems are not always linear or nonlinear.

Advanced Energy Materials, EarlyView.A weakly solvating ether solvent, 1,2‐dimethoxypropane (DMP), is proposed for use in localized high‐concentration electrolytes (LHCEs) for lithium metal batteries (LMBs). These DMP‐based LHCEs simultaneously suppress lithium metal corrosion and cathode degradation—two interrelated processes that accelerate calendar aging of LMBs.

Calendar Effects and Seasonality on Returns and Volatility [PDF]
SSRN Electronic Journal, 2009 This study examines the calendar effects in 55 Stock market exchange indices around the globe. The effects which are examined are the turn-of-the-Month effect, day-of-the-Week effect, Month-of the-Year effect and semi-Month effect. The methodology followed is the test hypothesis with bootstrap simulated t-statistics.

Advanced Energy Materials, EarlyView.This study introduces a multidimensional framework integrating electrical performance, cost, and life cycle assessment for 140 real and virtual battery cells. Results show that LFP offers low emissions and costs, sodium‐ion excels in resource efficiency, and pouch housings and higher energy densities effectively reduce environmental burdens.
