Spatiotemporal Characteristics and Multiscale Driving Mechanisms of Droughts and Floods in Jiangsu Province Based on EOF and Cross-Wavelet Analyses

Atmosphere
Based on monthly meteorological observations from 57 stations in Jiangsu Province during 1961–2022, the Standardized Precipitation Evapotranspiration Index (SPEI) was calculated to characterize regional dry–wet variability. Empirical Orthogonal Function (

Transitions in diatom assemblages and pigments through dry and wet season conditions in the Red River, Hanoi (Vietnam) [PDF]

Plant Ecology and Evolution, 2019
Background and aims – Biomonitoring is an important tool for assessing river water quality, but is not routinely applied in tropical rivers. Marked hydrological changes can occur between wet and dry season conditions in the tropics.

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Spatial and Temporal Analysis of Dry and Wet Spells in the Wadi Cheliff Basin, Algeria

Atmosphere, 2021
The Mediterranean Basin, located in a transition zone between the temperate and rainy climate of central Europe and the arid climate of North Africa, is considered a major hotspot of climate change, subject to water scarcity and drought.

Performance and economic viability of protein supplementation for grazing cattle steers in the wet and dry-wet transition season

Semina: Ciências Agrárias, 2016
The objective was to evaluate performance and economic viability of protein supplementation of grazing beef cattle in the wet and dry-wet transition season. Eighty non-castrated Nellore steers, body weight of 371 ± 11.3 kg were used in the experiment.

Adjusting Nucleation Chemistry for the Atomic Layer Deposition of Antimony Selenide on Metal Oxide Surfaces

Advanced Engineering Materials, EarlyView.
The ALD precursor bis(trimethylsilyl)selenide is simultaneously a substrate surface inhibitor. It allows for the growth of Sb2Se3 in combination with tris(dimethylamido)antimony, but also silylates surface hydroxyl groups on the substrate if such hydroxyls are present.

Edible Cuttlefish Ink: Complex Chemistry, Structure, and Electrical Response

Advanced Engineering Materials, EarlyView.
An integrated approach of chemistry‐structure‐electrical properties is used to assess the potential of edible cuttlefish ink as a bio‐based conductive ink for printable electronics. Chromatography and Neutron Activation Analysis reveal a fascinating molecular and elemental diversity.

Development and evaluation of a stochastic daily rainfall model with long-term variability [PDF]

Hydrology and Earth System Sciences, 2017
The primary objective of this study is to develop a stochastic rainfall generation model that can match not only the short resolution (daily) variability but also the longer resolution (monthly to multiyear) variability of observed rainfall.

Effect of Calendering and Surface Treatment on the Thermochromic Response of Cholesteric Liquid Crystals on PET Nonwovens

Advanced Engineering Materials, EarlyView.
This study explores the influences of calendering and surface treatment during direct ink writing (DIW) of thermochromic cholesteric liquid crystal (CLC) on PET nonwovens. For the PVA‐coated nonwovens, calendering reduces pore size leading to reduced ink absorption and enhanced spreading. The NeverWet‐coated nonwovens improve thermochromic responses by
