Hydraulic properties of peat soils along a bulk density gradient—A meta study
Hydrological Processes, 2018 Our understanding of hydraulic properties of peat soils is limited compared with that of mineral substrates. In this study, we aimed to deduce possible alterations of hydraulic properties of peat soils following degradation resulting from peat drainage ...

Combining Step Gradients and Linear Gradients in Density [PDF]
Analytical Chemistry, 2015 Combining aqueous multiphase systems (AMPS) and magnetic levitation (MagLev) provides a method to produce hybrid gradients in apparent density. AMPS—solutions of different polymers, salts, or surfactants that spontaneously separate into immiscible but predominantly aqueous phases—offer thermodynamically stable steps in density that can be tuned by the ...

The Buoyant Behavior of Viral and Bacterial DNA in Alkaline CsCl [PDF]
, 1963 In equilibrium density gradient centrifugation, the banding polymer species is electrically neutral. The banding species for a negative polyelectrolyte with a polyanion P_(n)^(-z)n (where n is the degree of polymerization, and z the titration charge per

Metrizamide, a new density‐gradient medium [PDF]
FEBS Letters, 1975 1. Introduction Isopycnic centrifugation has proved to be an extremely versatile technique for the fractionation of biological materials. However, there are some restric- tions on its use, mainly because of the physical and chemical characteristics of the compounds used to form the density gradients.

Density-Functional-Based Determination of the CH3-CH4 Hydrogen Exchange Reaction Barrier
, 1994 Due to the overbinding that is inherent in existing {\em local} approximations to the density-functional formalism, certain reaction energies have not been accessible.

Gradient design of imprinted anode for stable Zn-ion batteries
Nature Communications, 2023 Achieving long-term stable zinc anodes at high currents/capacities remains a great challenge for practical rechargeable zinc-ion batteries. Herein, we report an imprinted gradient zinc electrode that integrates gradient conductivity and hydrophilicity ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Control of laser wake field acceleration by plasma density profile [PDF]
, 2007 We show that both the maximum energy gain and the accelerated beam quality can be efficiently controlled by the plasma density profile. Choosing a proper density gradient one can uplift the dephasing limitation.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity
FEBS Letters, EarlyView.The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.
