Rechargeable Aqueous Microdroplet

open access: yesThe Journal of Physical Chemistry Letters, 2014
Directional and controllable transportation of microdroplets is critical for emerging micro- and nanotechnology, in which the conventional mechanical energy generation is not applicable. This Letter shows that an aqueous microdroplet can be charged for controlled motion in electrostatic potential, which was created by differentiating pH, between two ...

Interfacial and Crystallographic Regulation of Zinc Anode via Electric Double Layer Reconstruction for Highly Stable Zn Anode

open access: yesAdvanced Functional Materials, EarlyView.
Trace amounts of perfluoro‐1‐butanesulfonyl fluoride enables the regulation of the Zn/electrolyte interface by the generated zincophilic ─SO3H groups with long hydrophobic ─CF2 tails, which adsorb strongly onto the Zn surface, displace water molecules from the inner Helmholtz plane, and reconstruct the electrical double‐layer structure.

Characteristics of groundwater circulation in typical karst trough areas:A case study of Longtan trough valley in Youyang, Chongqing

open access: yesShuiwen dizhi gongcheng dizhi
Although the southwest karst valley region of China has an abundance of groundwater resources, little is known about the variations in the karst trough valley’s groundwater types and their cycle features. Using the Chongqing Youyang Longtan trough valley

Physical Structure of the Epikarst

open access: yesActa Carsologica, 2013
Epikarst is a weathered zone of enhanced porosity on or near the surface or at the soil/bedrock contact of many karst landscapes. The epikarst is essentially the upper boundary of a karst system but is also a reaction chamber where many organics ...

Response Of The Dupi Tila Aquifer to intensive pumping in Dhaka, Bangladesh [PDF]

open access: yes, 2003
This paper focuses on the water-quantity issues facing Dhaka because of the rapid exploitation of the Dupi Tila aquifer. Dhaka is one of the world’s largest groundwater-dependent cities, relying on water withdrawn from this underlying semiconfined sand ...

Sensorized Engineered Tissues with Built‐in Thermoregulation and Nutrient Supply

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a granular hydrogel‐based tissue engineering platform that includes a closed‐loop temperature control to maintain 37°C and sustainably releases nutrients, thereby enabling cells to retain a high viability even if stored at room temperature for up to 24 h.

Battery simulation program [PDF]

open access: yes, 1971
Computer program calculates spacecraft battery energy at specific times dictated by input sequence of recharge, discharge, and no activity phases. Recharge phases are assumed during times not specified, unless batteries are fully charged.

Estimation of aquifer lower layer hydraulic conductivity values through base flow hydrograph rising limb analysis [PDF]

open access: yes, 2010
The estimation of catchment-averaged aquifer hydraulic conductivity values is usually performed through a base flow recession analysis. Relationships between the first time derivatives of the base flow and the base flow values themselves, derived for ...

A Printed Zinc‐Ion Microbattery with Extended Shelf Life and Durability for Energy Autonomous Sensors

open access: yesAdvanced Functional Materials, EarlyView.
We present a fully printed aqueous zinc‐ion microbattery (ZnIB) enabled by graphene‐decorated zinc anode and printed MnO@NC cathode using sustainable aqueous‐based ink formulations. The printed 3D electrodes ensure uniform zinc deposition, low overpotential, and long‐term stability.
