Control of perennial weeds based on weed biology and environmental considerations [PDF]

open access: yes, 2013
Timing, type and duration of tillage operations and cropping practices are of importance for reducing the regeneration of perennial weeds and also for minimizing the environmental impacts of such operations.

Role of the Recombination Zone in Organic Light‐Emitting Devices

open access: yesAdvanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Maize Yield, Nitrogen Use Efficiency, and Growth Parameters as Influenced by Different Tillage Systems

open access: yesInternational Journal of Agronomy
Conventional tillage is widely applied to produce food crops in Iran which has notable harmful effects on the soil and the environment. In recent years, conservation tillage has been considered by farmers as an alternative and ecofriendly method in some ...

Der Einfluss von Minimalbodenbearbeitung, Zwischenfrüchten und Kompostdüngung auf pflanzenparasitäre Nematoden im Ökolandbau [PDF]

open access: yes, 2015
Plant parasitic nematodes (PPN) can be highly damaging towards plants managed organically. In particular, broad host range PPN (Pratylenchus spp., Meloidogyne spp.) increase under long crop rotations and high weed pressure.

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.

Agrotechnical and economical alternatives for pea culture in Turda area

open access: yes, 2016
The aims of this experiment are to evaluate the yield of pea cultivated in conventional and reduced tillage and the economy of minimum tillage systems application. Soil is the primary factor determining the plants yield of a particular area. Yield of pea

Microbial Community Structure and Litter Decomposition in Stratified Soils of a Long Term Reduced Tillage Experiment [PDF]

open access: yes, 2017
The aim of the present study was to examine decomposition of plant material (maize straw, green and rooibos tea) in stratified soils of the long-term tillage experiment, established in 1999 and shifted from conventional to organic farming system in 2015.

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

open access: yesAdvanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.
